DIY pipe bender. Making a pipe bender for a profile pipe with your own hands with dimensions and drawings Homemade rollers for a pipe bender for a profile pipe

When performing various works with pipes, it is often necessary to bend them in a certain shape to solve certain problems. This is done using a specialized mechanical unit - a pipe bender. Next we will look at how to make a manual pipe bender for a round profile pipe do it yourself, photos, videos and drawings will simplify the task and help you avoid mistakes.

One type of simple pipe bender

Of course, you can always buy industrial version. But such equipment is quite difficult to use, and in terms of cost it cannot be called the most affordable. Therefore, as a rule, it is much more expedient to make a manual pipe bender for a profile pipe with your own hands; drawings and dimensions are presented below, so you should not have any difficulties. Various available tools will be useful for production. Such a tool is quite economical in terms of production and very functional.

So, we make the simplest pipe bender for a profile pipe with our own hands.

As a rule, in household or garage conditions make front-configuration equipment, structurally consisting of the following components:

  • 3 steel rollers;
  • drive chains;
  • rotational axes;
  • the mechanism that activates the components of the finished system;
  • steel profiles required for the construction of the main structural parts.

Before you start making a pipe bender with your own hands for a profile pipe, study photos, videos, diagrams and drawings. You should approach the selection and work (and especially their refinement or adaptation) with extreme care with drawings, since it is extremely important to achieve high precision and the correctness of the design from an engineering point of view. You can use drawings from different models of pipe benders. But it’s better to take a simpler one, the optimal solution is a front-type machine.

Diagram of a simple pipe bender

Often, pipe benders are made with their own hands using wooden or polyurethane rollers. This decision should be approached carefully, since these materials are not always able to withstand the loads you need. It is necessary to build on the strength properties of corrugated pipes.

To build a pipe bender for a profile at home with your own hands, you need drawings of a model that suits you. Below is one of the varieties of this drawing, which you can use to produce this type of equipment:

Drawing of one of the bending machine models

To understand how to properly make a pipe bender with your own hands, watch the video, drawings and description of the operating technology. It is very important to understand the technological side of the process. Typically, such equipment operates on the principle of rolling or rolling, thereby minimizing the likelihood of fracture and damage to the pipe.

The pipe is placed between the installation shafts, after which the handle is turned. The technology is extremely simple, but it makes it possible to bend products according to clearly defined parameters and, as a result, obtain the ideal part for solving the task.

Bending system based on a jack

Everything you need to build a pipe bender for a profile pipe with your own hands in a garage using available funds - dimensions, drawings and photos can be downloaded in this material. We also recommend that you watch a video on YouTube about a pipe bender with your own hands, this will allow you to clearly see the entire manufacturing process and evaluate possible difficulties in a specific case.

To create this tool you will need the following components:

  • simple jack;
  • profiles and a shelf made of durable steel (the frame will be constructed from them);
  • very strong springs;
  • 3 shafts;
  • drive chain;
  • other components (bolts and other small parts).

We make a pipe bender for a professional pipe with our own hands (photos, drawings, pictures)

It is quite simple to build this kind of mechanical system, but it is extremely important to adhere to a clear sequence of actions and accuracy. Everything must strictly comply with the drawings, otherwise the tool will bend the profile incorrectly. To build a pipe bender for a profile pipe with your own hands, you need pictures and drawings, which you can download for free in this material.

All manufacturing process is divided into several key stages:

  1. Preparing a reliable frame. For connection components Bolts and welding should be used.
  2. Installation of the rotation axis and rollers. One shaft is installed below the other two. The distance between the axes of the shafts is determined by the bending angle of the pipe. At this stage, it is important to install the elements strictly according to the drawing.
  3. The mechanical part is driven by a chain-type transmission. Its design should have 3 gears. It is not necessary to use a new chain; you can take an old one from any equipment.
  4. A handle is installed on one of the shafts, making it quite easy to rotate it with light movements without special effort. The handle is one of the key components of the mechanism for generating the required torque.

There is nothing complicated in the procedure for constructing such equipment, the main thing is to follow simple rules and drawing.

The manufacturing process involves performing next sequence actions:

  1. Install the rings, gears and bearings onto the pressure shaft. Connections are made using a keyway method. Initially, you need to draw all the named elements, then turn them into lathe. The design will have 3 shafts (2 on the sides and 1 suspended on a spring).
  2. Make holes in the rings to create grooves and threads.
  3. Make a shelf (for the production of this part a channel is used, preferably strong and massive). In the latter, also make holes and cut threads to make it possible to install the pressure shaft.
  4. Assemble components into a single system. To connect, use bolts and a welding machine. First, assemble the frame, which also serves as the legs of the unit.
  5. Hang the shelf with the pressure shaft fixed on it. At this point you will need good springs. Install the support shafts on the sides. A handle should be installed on one of the latter.
  6. At the final stage, the jack is installed on the equipment.

For a better understanding of the process, watch how a homemade pipe bender is made from a jack for a profile pipe with your own hands - video on YouTube:

From the above we conclude that making a rolling pipe bender with your own hands from scrap materials is quite simple.

But the manufacturing process is characterized by certain subtleties that should be taken into account:

  • the pressure shaft attached by means of keys must also be screwed to the shelf;
  • in the process of fixing the pressure shaft, perform the actions in the following sequence: before mounting the shaft to the shelf, it is necessary to weld nuts to it, to which the springs will cling; upon completion of installation, you need to turn the shelf over and hang it using springs of suitable strength;
  • A magnetic corner that functions as a holder is perfect for tensioning the chain;
  • the stars are twisted using dowels (to make the latter, use a Grover);
  • provide a scrolling tube on the drive handle, this will make working much more convenient and easier;
  • The installation of the jack must be carried out on a suspended platform (to make all connections, we again use ordinary bolts or welding machine where necessary).

Making a hydraulic pipe bender for a profile pipe with your own hands (drawings and video)

This page contains all the required information, after studying which you can build the simplest machine DIY pipe bender with jack (drawings, photos, videos and instructions). Many masters, especially professional level, build a unit equipped with a hydraulic drive, as this increases functionality. But, producing such equipment is somewhat more difficult in comparison with the option discussed above. It's pretty labor-intensive process. Therefore, we recommend that you watch a video that demonstrates in detail the manufacturing process of this device.

How to assemble a universal pipe bender with your own hands - watch the video:

Based on the design and drawing of this unit, we highlight the components included in its design:

  • hydraulic jack (must be designed for loads weighing over 5 tons);
  • shoe;
  • 2-3 videos;
  • durable steel channel;
  • thick steel plates and other elements.

To achieve the required bending parameters of the product on such a homemade machine, it should be placed in the shoe, secured on both sides. Then a jack is used, the lifting rod of which exerts pressure on the shaft. The latter, in turn, directly influences the fixed product, gradually performing the required bending. Once the pipe has been bent to the predetermined specifications, it can be dismantled. To do this, it is enough to turn the jacking mechanism back a little to relax the entire system.

  2. Fix the steel plate on the bottom platform where the jack will be mounted. Secure everything with bolts and install the drive handle.
  3. It is extremely important to select the appropriate rollers for the pipe. It is necessary to ensure a tight grip of the product. If you can’t find ready-made ones, you can make homemade ones. The shoe is installed under the rollers. The location of the latter relative to each other is established based on the bending radius required in a particular case.
  4. To secure the shafts with the shoe, make bolted connections. The drawing below contains all the hole parameters.

Technological aspects of the bending process

By following simple tips, you will avoid problems and mistakes during the bending process. Hydraulic units allow you to bend corrugated pipe from almost any material, including those with walls of quite significant thickness. There is a hot and cold ways bending of products.

A type of device with a jack

The easiest way is to use the cold bending method. This technology is suitable for products made of plastic materials. The peculiarity is that the corrugated pipe must first be filled with sand, salt, oil or cold water. Due to this, it is possible to significantly improve the quality of bending, eliminating damage to the product.

If you plan to bend a thick-walled pipe, you should use the hot method.

Various shafts for various types pipes

  • In a manual machine, the absence of sprockets is allowed. The device can be built on a single drive roller. The clamping screw can be replaced with a jack.
  • Use steel hooks to prevent the corrugated pipe from slipping during pattern bending.
  • If you need to achieve a large bending radius, you should use a machine equipped with 3 rollers.
  • To achieve the versatility of the device, it is worth ensuring the mobility of the thrust rollers. This will allow you to adjust the radius.

Watch the following video to understand how a budget DIY profile pipe bender works (YouTube):

For achievement maximum accuracy bending, it is recommended to use a special template. It is easy to make from wood. This solution allows you to achieve perfect accuracy even on the simplest homemade machine.

A pipe bender is used to bend profile pipes. This is a tool designed to deform profile pipes. Devices of this kind are sold ready-made or made independently. The second option is popular, since a homemade pipe bender can be made from improvised materials and it will cost tens of times less.

What is the unit for?

To bend a profile pipe, you do not need to turn to rolled metal for help or buy special tool. This can be done using two metal posts buried in the ground. However, this method has a significant drawback - the need for physical effort. The result is an inaccurately curved pipe, which is not suitable for constructing a greenhouse, arch or other products.

A pipe bender is designed to be able to produce neatly curved pipe shapes. These units are subsequently used for the construction of arches, greenhouses, ceilings, gazebos, fences, etc. If you set out to build a greenhouse at home, then you need to design a homemade pipe bender. If there are available products and tools for this, then implementing the design of the device with your own hands will not be difficult.

To make a roller pipe bender with your own hands for a profile pipe, you need to take care of the drawings. They are used to calculate the required amount of material, as well as the costs of producing a home-made unit.

The planned design of the product is applied to the drawing, which depends on the materials available.

Most craftsmen choose to manufacture front-type pipe bending machines. Such products consist of the following components:

  1. Rollers presented in the form of a round steel pipe (the number of required rollers is 3 pieces).
  2. Chain driving shafts.
  3. Axes of rotation.
  4. The mechanism that drives the device.
  5. Profiles that are used to make a base or frame.

Use as rollers soft species materials is unacceptable, as this may lead to them not withstanding high load, and will collapse. It is recommended to use metal round pipes as rollers.

It is worth noting that there are a huge number of manufacturing options for the products in question, but they all operate on the principle of rolling or rolling. It is this principle of pipe bending that makes it possible to reduce the risk of pipe bending and cracking.

A simple pipe bender has the form of a unit into which a profile pipe is inserted, after which the handle is turned, when rotated the pipe begins to move and a bend is formed. When constructing a home-made unit at home, it is important to consider that the bending parameters will depend on the design itself. The closer the pressure rollers are to each other, the smaller the angle.

The simplest pipe bending machine: what materials will be needed

The simplest homemade pipe bender, in which the bend angle is adjusted, is made using the following materials:

  1. Hydraulic jack.
  2. Metal profiles that serve as the basis for the construction of the structure.
  3. High-strength springs - 4 pcs.
  4. Metal shafts - 3 pcs.
  5. Chain.

When designing a pipe bender with adjustable bending angles, two rollers are located on the lower base, and the third is installed in the upper part. When obtaining the desired bend, you only need to rotate the handle, which will move the shaft using a chain mechanism.

To create the device shown in the photo above, there is no need to make grooves to adjust the location of the rollers, which will significantly simplify the work. To obtain such a product, you only need required material and a welding machine. The rest is the work of the master. It all depends not only on your skill in welding and grinding, but also on your imagination.

Where does the production of a pipe bender begin?

A homemade pipe bender is made by performing the following manipulations:

  1. Frame manufacturing. The lifespan of the manufactured device depends on the quality of the materials used and welds. Welding is not the only option for creating a base, as you can use a drill and bolted elements.
  2. Set the axis of rotation, as well as the shafts themselves, depending on the dimensions of the drawings. Two shafts are installed below the third. The distance between the axes of these shafts is the bending radius of the profile pipe. This needs to be taken care of even before the shafts are fixed to the base.
  3. The device will not work if the shaft is not activated. For this, a chain drive is used, which can have 3 gears. Chain drive is not mandatory element devices, since only one shaft can be driven to move the profile product through such a tool. If it is decided to equip the device with a chain mechanism, then the chain and gears are taken from the gearbox of a car or motorcycle.
  4. A special handle will help simplify the process of rotating the shafts. With the help of such a handle, a torque will be created to ultimately obtain a curved pipe.

The pipe bender device does not represent great complexity, but its creation must be taken responsibly. Make a device using a quick fix will not be difficult, but whether such a tool will be effective and reliable, it all depends on thinking through every little detail. To adjust the angle or radius of the resulting bend of the profile pipe, it is necessary to make one of the shafts adjustable. This will make it possible to obtain products of different radii, which are used not only for the construction of greenhouses, but also arches, gazebos or entrance gates.

How to make a pipe bender with your own hands: instructions

If you have an example or diagram of a pipe bender, then making the machine yourself will not be difficult. You must adhere to the appropriate sequence of actions. To make a pipe bender for a profile pipe, the following manipulations are performed:

  1. On the shaft you need to place gears, as well as bearings and rings. The production of shafts is entrusted to an experienced turner. If you plan to create all the parts yourself, then you will need three shafts, two of which are distributed on the lower base (a channel serves), and the third is suspended on springs.
  2. The corresponding holes are drilled in the rings, which are needed in order to cut the thread. This thread is needed to attach gears to the shafts.
  3. The shelf for securing the third roller is also made from a channel.
  4. All elements are distributed on the frame and combined by welding or bolted connections.
  5. The first step is to install the frame on which the corresponding structural elements are distributed.
  6. The shelf is welded perpendicularly to the base.
  7. A handle is attached to one of the shafts.
  8. Finally, to adjust the bending radius of the profile pipes, you need to install a hydraulic jack on the top shelf.

If you make a tool according to a template, then no difficulties will arise. To clarify some points, you should pay attention to the following factors:

  1. The pressure shaft located on the shelf must be additionally secured to it. It is also secured with dowels.
  2. The pressure roller is made by performing the following manipulations: a shaft is fixed to the shelf, as well as springs that are attached to pre-installed nuts. After making the shelf, it can be welded to the frame of the main device.
  3. To tension the chain, you need to use a magnetic corner. It will serve as a holder.
  4. The sprockets are fixed with dowels made from Grover.
  5. The drive handle is constructed from a steel tube.
  6. The jack is placed on a hanging shelf.

The design of the simplest homemade unit for bending profiled pipes is presented in the video below.

How to build a hydraulic pipe bender

The design of a hydraulic pipe bender with your own hands is presented in the video below.

Building a tool of this type will not be difficult if you have two 0.5 meter channels at your disposal. The base of such a device included the following elements:

  • hydraulic cylinder;
  • stops;
  • supercharger.

In addition, you should also highlight:

  1. A jack that can withstand loads of up to 5 tons.
  2. There are 2-3 rollers.
  3. Channel - 3-4 mm.
  4. Thick plates.

The principle of using such a tool is that you need to install a profiled pipe into the shoe. Use a jack to set the required bending radius. When the jack is inflated, the rod rises, pressing on the roller. After establishing the bending angle, the pipe can be removed. This type of bending device is relevant when it is necessary to bend a pipe in one place, for example, when installing a heating system.

Crossbow pipe bender: step-by-step design instructions

The crossbow bender got its name because it resembles the shape of a hand crossbow. The cost of crossbow devices is about 10 thousand rubles. To save on the purchase of such a unit, it is recommended to make it yourself.

The photo shows two options for crossbow devices for bending pipes. The first option is a factory design, and the second is a homemade machine. The difference between these two machines is significant, since the factory version is made of steel measuring no more than 2 mm, while for the homemade one, metal 3-4 mm thick was used. This means that the homemade unit was made not just to have it, but for everyday use.

Feeling the difference, every master will want to acquire crossbow pipe bender by making it yourself. The disadvantage of this version of the pipe bender is the fact that it allows you to bend the corrugated pipe at only one point. This is due to the fact that the device is equipped with a fixed shoe. This option is used for round pipes when you need to obtain a certain bending radius in one place.

To construct such a device, you need a channel and a hydraulic jack. A special shelf is made for the jack in which it is installed. In the upper working part, two rollers made of steel pipe are mounted between two channels. The distance between the rollers and the heel of the jack must be the same in order to be able to obtain even and neat bends.

Other options for rolling pipe benders

You can make a manual pipe bender using two steel plates, as well as four metal bars measuring at least 4x4 cm. The reliability of the structure will depend on the thickness of the bars. An example of another type of rolling pipe bender is shown in the photo below.

Initially, a frame is made with 3 rollers fixed on it. Two rollers are stationary and are placed on the side posts. A hole is drilled in the upper base (steel plate) and a thread is cut. This thread is needed to adjust the third movable roller. WITH reverse side installation, a handle is placed, which can be presented in the form of a wheel. When the wheel rotates, the pipe will automatically roll and bend. The bending radius is adjustable using a threaded connection.

This is not the most simple design, however, with the right approach it will serve for a long time. If you need to make the product easier, then below is a diagram with all the necessary dimensions.

Stationary pipe bender: step-by-step instructions

If you plan to make your own greenhouse from steel pipes, then you will need to acquire not just an ordinary pipe bender, but a reliable product. After all, with this approach you will need to bend more than a dozen profile pipes. To make the greenhouse design neat and beautiful, you need to use a stationary pipe bender.

Before you start making a greenhouse, you need to make sure that you have the appropriate tool for bending profile products. The following elements will be needed to construct a stationary pipe bender:

  • rod at 25;
  • 6 bearings;
  • channel.

You will also need a welding machine, which will be used to connect all the components. Step-by-step instruction making a stationary pipe bender looks like this:


When installing a profile tube of any size, you should adjust the radius of the final bend. This can be done using a jack located under the base on which one of the shafts is fixed. Having adjusted the required bending radius, the handle rotates. The result is high-quality curved tubes. The advantage of a pipe bender is the ability to bend materials of any size and diameter.

Among the disadvantages, we can only note the possibility of operation in one place. It is important to understand that such a device can be used for any need. To manufacture such a device, an investment of no more than 500 rubles will be required. You only need to buy 6 bearings, and all the other elements can be found in every craftsman’s household.

How to bend a pipe with a homemade pipe bender

Making the devices in question with your own hands is only half the battle. After this, you will still need to use the tool correctly. You can watch the video to see how to use the tool.

The methods for manufacturing manual pipe benders, which are suitable for cold bending of pipes, are discussed above. This is an option whereby the material is not subject to heating. This option can be used for plastic materials. To increase the efficiency of bending, you need to fill the inside of the product with sand or salt. Filling the internal cavity of the material with sand or salt will eliminate deformation of the pipe, as well as obtain a high-quality bend.

If the walls of the pipe are thick, then it will not be possible to bend it using a cold method. For this, a hot method is used, which involves preheating the bending point.

Note to the masters

Useful advice from experts is always popular and in demand. Based on the experience of the master, you can avoid various mistakes when carrying out the relevant work:

  1. IN hand-held devices It is not at all necessary to resort to installing a chain drive, since the design will function when only one shaft moves.
  2. To prevent the pipe from sliding off the template used to bend it, you need to use appropriate metal hooks.
  3. If you need to bend a pipe with a large radius, then three rollers are used.
  4. When designing manual machine care should be taken in advance to be able to adjust the bending radius.

The video shows another option for making a manual pipe bender with two stars. Useful thing, which does not require large economic and physical waste.

If you have a pipe bender at your disposal, you can even make money with it. After all, with its help you can not only bend a profile pipe, but also fittings, obtaining the necessary patterns. Curved reinforcement is used to make decorative elements for entrance gates, canopies, awnings, etc.

Pipe bender a device designed for bending a profile pipe with your own hands. When constructing greenhouses, greenhouses, and gazebos, it can be used to produce various radii of curvature. Such a device can not only be bought, but also quite easily made with your own hands.

Main design elements

A simple homemade pipe bender for professional pipes consists of the following parts:

  • The bed is a structure made of a channel or angle 600-700 mm long, solid or consisting of two parts hingedly connected to each other.
  • The front and rear shafts are made of durable steel and have a diameter of 40-50 mm, length - 60-80 mm. The ends of the shafts are machined to match the inner diameter of the bearings used to rotate them.
  • The central shaft is located in the middle of the structure and serves to support and bend the profile passing under it. One of its axes should protrude from the bearing.
  • Bearing races - pieces thick-walled pipes. Designed for pressing bearings into them and welding them to the frame.
  • Handle - attached to the protruding axis of the front or rear shaft.

Also often, to reduce the effort when bending a profile, a homemade pipe bender in its design contains two gears, a chain and a tension roller.

The gears are mounted on the axles of the front and rear shafts, a chain is pulled between them, fixing its tension with a roller. In this design, the handle is attached to the axis of the front or rear shaft rather than the central one.

To fasten such a device, long screws are used and with which it securely fixed on a workbench or table.

Important! The most exposed parts of a pipe bender are the shafts; they should be made of durable tool steel.

If less strong structural steels are used as a material for shafts, there is a high risk of rapid wear or breakage. In addition, such shafts will not provide high-quality pipe bending.

How to make a pipe bender with your own hands

To make a pipe bender, you need to prepare the necessary and materials, make drawings , both its individual parts and the entire assembled product. Based on these compiled graphic images the components of this device should be manufactured and assembled into a single whole.

Materials and tools

To make a pipe bender you need the following tools:

  • grinder with cutting wheel for metal;
  • drill or drilling machine;
  • hammer;
  • vice;
  • metal brush.

In addition to tools for the manufacture of such devices, you need the following materials:

  • channel 8P - about 2 meters;
  • bearings 205 – 6 pcs.;
  • shafts – 3 pcs.;
  • thick-walled pipe with an internal diameter of 52-53 mm;
  • handle with holder;
  • garage curtains;
  • car hydraulic jack.

To paint the manufactured structure you will need Oil paint , solvent.

How to make a pipe bender

You can make a reliable and simple pipe bender with your own hands in the following way:


Such a homemade pipe bender for a profile pipe with a square, rectangular or oval cross-section will allow you to minimal investment create arched structures required sizes.

How to make a hydraulic pipe bender

Using the device described above, it will not be possible to bend profile pipes at an angle of more than 50-60 degrees. For such purposes you will need hydraulic pipe bender, having a different design and principle of operation.

Making such a device yourself is quite simple. The entire assembly process consists of the following stages:

  1. To a metal plate with dimensions of two sides of 300×300 mm and a thickness of 8-10 mm 4 corners are welded length 300-350 mm.
  2. Two channels are welded to the corners with advance drilled holes for support rollers. The holes on the channels are not located in one line, but in a ladder - this allows you to change the bending angles of the pipe.
  3. A jack is installed on the slab.
  4. A “shoe” is put on the jack rod - an attachment for bending a pipe in the shape of a semicircle.
  5. The support rollers are made of durable steel and have through holes in the center - they are designed for axles.

To bend a pipe using such a device, first, support rollers are installed in the appropriate positions, then a jack with a shoe.

After this, the shoe, by lifting it with the jack rod, is installed at such a distance from the plane of the support rollers that the profile can be inserted there. Next, by lifting the shoe with the jack rod, the profile is bent at the required angle.

Making a similar pipe bender for a profile pipe with your own hands, a “shoe” and shafts best to buy rather than making it yourself.

Pipe bending methods

Since the manufacture of a profile pipe involves the use of metal of various thicknesses, when bending pipes using the methods described above homemade devices apply the following methods:

  • Cold – involves bending the profile pipe at the required angle without heating. To prevent unwanted deformations and fractures of the profile from occurring during the bending process, dry sand is poured inside it. The sand to be poured should be very fine and there should be no stones in it.
  • Hot – when bending pipes using the hot method, the profile preheated using a burner. This makes the material more flexible and eliminates fractures and deformations. The disadvantage of this method is the formation of an oxide film on the surface of the profile and the susceptibility of the product made from such a pipe to corrosion.

Important! Hot way bending used for profile pipes with great thickness walls. It should not be used for thin-walled profiles - this will increase their corrosion and create an additional risk of unwanted deformations, cracks and fractures during the bending process.

When hot bending is very it's important not to overheat metal - the color of the heated material should be rich red or crimson. Do not heat the profile to a bright white or faint red color. In the first case, the material is very overheated and the bending due to excessive softening of the metal may be too great; in the second case, on the contrary, it is weakly heated and may crack or break during bending.

Types of pipe benders

Depending on the design, type of drive, cost, everything pipe benders are divided for the following types:

  • Angle pipe bending machine – most common and the simple appearance of this tool. Used for bending pipes and profiles of various sections and diameters.
  • Manual – portable compact tool. Applicable small section.
  • Hydraulic – used for profile and round pipes of various diameters. Thanks to the smooth bending process, such equipment allows you to obtain products of the most High Quality.
  • Electric is quite bulky, complex and expensive equipment. Designed to do high-precision work. Used for production purposes.

Important! To make arches, it is better to make a manual pipe bender with your own hands, or purchase the simplest factory model.

It is not advisable to buy expensive ones for such needs. professional models electric and hydraulic pipe benders.

A real owner always has plenty various instruments, which he uses for his house and plot. And he, of course, will be able to make a pipe bender for a profile pipe with his own hands according to the dimensions and drawings that we will provide below. Such designs may be different, and we will not be able to cover them all, but the material provided will be enough for you.

Homemade pipe bender

Buy in a store or make it yourself

Profile pipe bender "Hercules"

The one you can buy in the store may have different type drive and different principle actions, but this is not always good. Firstly, to work on it you need some experience, and secondly, such devices have high cost. For these reasons, making a homemade pipe bender from scrap materials is not only profitable, but also practical, since when assembling the tool you will know the slightest nuances of its operation.

Why do you need a pipe bender?

Main elements of the machine

Today, profile pipes of different cross section is the most popular metal product. They are used to make frames and lathing, fences and railings, with their help they expand balconies and even build various architectural structures in the form of extensions or separate rooms. But sharp turns are not always used in construction - sometimes a smooth transition is needed, and in these cases you can’t do without a pipe bender. As a rule, such a machine allows you to bend a profile to an angle of 180⁰, that is, the device allows you to make a circle.

Main design elements

Principle of operation

To manufacture a particular machine design, you should look through several diagrams to determine the set of parts. The fact is that, if necessary, all the components of the units can be purchased for money, but you can also use the materials that you have on your farm and not pay anything for it. In most cases, home craftsmen opt for frontal structures, and for this you must have:

  • three metal rollers (rollers);
  • drive chain;
  • axes of rotation;
  • drive mechanism;
  • metal profiles (channels) for the frame.

Sometimes, in the absence of metal rollers, they are replaced with wooden or polyurethane ones, but... Such a rolling mechanism will not withstand long-term load, that is, the machine will serve its purpose, but not for long. Is there any point in wasting your labor for short-term benefit if, with some effort or even paying a certain amount, you can find steel rollers?

As you understand, the process of profile deformation occurs using rolling, that is, the pipe is rolled over rollers (rollers), which eliminates breaking and cracking. To roll (bend) a profile, it is inserted into the rolling line (between the rollers) and pressed from above with a screw device or a jack to the desired bending radius. Then, when the feed handle is rotated, the pipe moves and the bend runs along its entire length. It turns out that this manual drive, which is driven by muscular force, but at home such a mechanism is very convenient.

The profile is pressed using a jack

To assemble the simple pipe bender in question with your own hands, you will need:

  • jack (preferably rack and pinion type);
  • metal profiles with a shelf for horizontal and vertical frames;
  • springs made of alloy steel (they are distinguished by high strength);
  • three steel shafts with bearings;
  • drive chain (can be from a bicycle or moped);
  • gears (driver and driven);
  • Thick reinforcement for axles and drive handle.

As you can see, it is easier to make a profile bending machine with your own hands using the existing drawings, and photo and video materials only help with this. The profile bender shown in the picture is driven by a handle that rotates the shaft with the drive gear. Using a chain, rotation is transmitted to the shaft with the driven gear, and the third shaft presses the profile from above to the required bending angle. Everything is very simple.

Mechanism manufacturing process

Bending device drawings

If you are interested in how to make a profile bender, then you will have to perform a number of actions that will ensure this reliability of the mechanism, and this is:

  • production of a powerful frame assembled using welding and bolt ties;
  • according to the terms of the drawing ( terms of reference) make and install rotation axes for the rollers. There are three of them - two rolling and one clamping;
  • To rotate the rolling rollers, you need to provide a chain transmission, that is, weld (evenly) the drive and driven gears;
  • Weld a handle for rotation onto the drive gear.

Manufacturing nuances

Ready pipe bender

If you have everything in stock necessary details, then it is not difficult to make a mechanism for bending the profile. First of all, you need to take into account that all rollers must rotate on bearings - the accuracy of rotation will ensure correct rolling, without failures or breaks. The drive and driven gears must be correctly centered - a deviation from the center by at least 0.5 mm will lead to incorrect deformation (the bend will be uneven).

The pressure shaft must also be centered - the accuracy of the bending angle depends on this. It is best when the dimensions of all three shafts are the same - the rental results in the clearest. The rolling accuracy also depends on the rigidity of the clamp, so the shaft must be well fixed.

Hydraulic pipe bender

Hydraulic drive mechanism

To make a hydraulic one for a profile pipe with your own hands according to ready-made dimensions and drawings, you will have to spend a lot more labor and resources. However, it can be done and we will now look at the procedure. For assembly you will need:

  • hydraulic jack with a lifting capacity of 5 tons;
  • shoe;
  • three shafts;
  • channel for frame;
  • metal plates (thick).

To correctly bend the profile, it is inserted into the shoe and both ends are secured. After this, the jack is activated - it presses on the pressure shaft and sets the desired bending angle. After rolling, the jack is loosened several turns and the pipe is removed from the device.

The jack is attached to a metal plate using bolted connections. But in such a mechanism, the most important thing is the shafts, which must tightly grip the profile - the accuracy of bending depends on this. The shafts are fixed at the same height and gears are welded to them. The shoe is attached below the shafts, and the ratio of the shoe to the shafts determines the bending angle. Fixation occurs using bolts.

Bending Methods

Cold profile bending

If you have read all the descriptions, looked at the photos and videos, then the bending process itself is unlikely to confuse you. If you decide to make a hydraulic device, then you can bend pipes of any thickness on it - the most important thing is that the shafts (rollers) can withstand it. But I would like to mention one nuance - arching can be not only cold, but also hot. Heating usually occurs using gas welding, this is very convenient, especially since you can heat only part of the pipe, that is, the section that needs to be bent.

It can be said that cold method bending is the simplest and if you are working with a thin-walled pipe, then you do not need to heat it at all. But there can also be problems here - this is the seam. Profiles are not always made with high quality and a bad seam simply comes apart when bent. This can be avoided by heating, but not always. A low-quality pipe will remain that way and no amount of heating will help. However, if you use a profile for the frame, then small crack along the seam will not become critical in any way.

Note. Be that as it may, hot bending is still the highest quality. The hot metal turns out to be most clearly curved, without any interruptions.

Pipe bender with components

For a profile pipe, it is not at all necessary to acquire any special qualifications - ordinary care and a few recommendations from specialists are enough. In manual devices, the system consists of a drive and driven gear welded onto shafts and a clamp (a jack can be used instead of a shaft). Sometimes the profile can slip off the rolling mill and in such situations, hooks are used for fixation. For the most precise bending, the shafts must be movable.

Note. To maintain the bending radius, it is best to make cardboard or wooden template. Even if you use a simple hand pipe bender, a template will always ensure accuracy.

Conclusion

You have read an article with drawings, photos and videos about how to make profile bending with your own hands. As you can see, this is not very difficult, but you need to collect all the parts first so that the work does not stop because of the little things.

To every owner of a big garden plot or a small dacha, at least once in your life (at least) you may need a pipe bender - a device for bending a profile pipe.

For example, this could be a blank for greenhouse frame or canopy, gazebo, or any other metal structures.

Metal sales centers and other industries usually use factory-made devices, but this pleasure is far from cheap. To save your budget for more pleasant expenses, it is more profitable to make the device manually, on your own.

For this design, as they say, “you don’t need a lot of intelligence,” and there won’t be a shortage of parts either; you can actually create the drawings of a pipe bender yourself.

Pipe bender options

You can bend the pipe using the “home” method, fill the pipe with sand, heat it until red blowtorch or gas burner, then bend the pipe. This method is not recognized as a priority among craftsmen; it is labor-intensive and does not provide sufficient accuracy; creases and deformations may also appear.

To obtain a perfectly bent pipe, in compliance with the standards and given parameters, do not cause damage source material, craftsmen use specialized pipe benders in their work.

Lever-type pipe benders have become very popular. This elementary invention works on the principle of a “lever” - the force is concentrated in a certain place, and the bend merges with the shape of the template you created, which can most often be removed and replaced with another.

Most often, the kit of such structures includes a couple of additional templates for pipes of different diameters. There are units similar in design, manual pipe benders, drone or crossbow, they allow you to bend short sections of round steel pipes, subjecting them only to cold working.

Crossbow devices are very compact and are valued in the field of installation and engineering communications.

What is the job of a pipe bender?

The principle of operation is completely simple, it consists in heating the pipe, the pipe heats up red and becomes very plastic, malleable to change. Each type of pipe bender has its own range of capabilities.

The main functions are the quality of bending and the ability to bend pipes different sizes and diameter.

With the help of additional rolling devices, a bend of a larger diameter is achieved. The device operates using shafts, there are three of them in the set.

Guides and pressure. The pipe passes through moving elements, the degree of bending is set by the force of the pressure roller. If the radius of curvature finished product turned out to be small, the procedure should be repeated.

Bending a pipe according to a template

In most cases, the simplest option, suitable for absolutely all craftsmen, even beginners, is a wooden template. Boards are selected according to the thickness of the pipes being bent; be sure to leave a couple of centimeters of board space.

To prevent the profile from moving off the template during operation, a slope is left at the ends. The template is rigidly fixed to the floor or other stable surface, and a stop for the pipe is installed nearby.

The profile is inserted into the gap between the template and the stop, smoothly and carefully press on its other end, pressing the pipe against the template. A winch or lever will make the job easier.

A huge advantage of this process is cost savings and ease of execution.

Note!

Any device has disadvantages, and this method is no exception. The bending is not accurate Bad quality, and the template will be disposable (apply only to one pipe diameter).

Snail pipe bender

When stamping identical blanks in large quantities with a small radius of curvature, a snail pipe bender will become indispensable.

Its advantage is its small size and ease of operation. The disadvantage will be the limitation of the radius of curvature, but not large sizes.

Rolling pipe benders

The niche of versatility and practicality is occupied by hand-made devices - rolling pipe benders ( bending machines), on such machines you can make any bending angle.

The configuration is not particularly different from other models; they also have a base and shafts. The movable roller presses the pipe, and it is pulled through by the rotation of the drive shafts.

Note!

Pressure can be increased using a winch, levers or electric drive. However, for the production of a house, such a design is quite complex to implement.

To reproduce such a unit, a lot of turning and welding will be required. If you decide to make such a model, it will serve you for a long time and will delight you with its functionality.

How to make a pipe bender with your own hands, the question is modern world quite relevant. To make the task easier, you can find a photo of a pipe bender on the Internet to roughly understand what it should look like.

There are also many pipe bender drawings that are easy to use. After reviewing all the information and assessing your strengths and availability necessary components, calmly get to work.
