Combination shears are the most versatile type of separating equipment: they can be used to cut wide strips, long products, specialized profiles, and even punch holes in sheet blanks. The combined shear press NG 5222 is a further development of the basic model; any press shop or area at industrial or construction enterprises has similar equipment.
The passport for this equipment, which is produced by the Kuvandyk plant KPO Dolina, provides the following technical characteristics:

Overall dimensions, weight, as well as other design parameters available in the description fully comply with the requirements of GOST 7355. The manufacturer has the right to make minor changes to the design that do not lead to a deterioration in the operational capabilities of the scissors. These changes are reflected in the product passport.
Scissors model NG5222 include:
The unit is controlled using a system of levers that are kinematically connected to two control electromagnets. When the drive rods are switched into the corresponding slots, either the punch of the punching press moves or the balancer of the rolling cutting section swings. The scissors can operate in single and continuous stroke modes. It should be taken into account that, due to the absence of an engagement clutch, the stop of the slide occurs within a certain time.
The cutting tool is fastened in special grooves in the slide. Installation of the punching punch is carried out in the punch holder, while the matrix is installed on the punching table.
The scissors passport also includes a list of necessary tools and accessories, including handles for fixing the table and centering device, sets of punches and knives, a receiving tray and a number of others. A tool for cutting special rolled profiles is also available as an option.
This is how scissors work. The torque from the switched-on electric motor is transmitted by a V-belt transmission to the flywheel, which compensates for possible fluctuations in the shaft speed due to force overload of the shears. Next, using a spur gear, the movement is transmitted to the eccentric shaft, on which a connecting rod is mounted to drive the slider of the section cutting mechanism and the rod of the swinging balancer, which controls the movement of the punching press. If it is necessary to punch holes, the corresponding control electromagnet is turned on, which rotates the multi-link lever and produces a translational movement of the punch downwards, while a continuously swinging balancer is responsible for returning the punch to its uppermost position. To cut long or round rolled metal, a second electromagnet is turned on. He turns the double lever, which in turn pushes the connecting rod down. It imparts a rocking motion to the slider, and at the same time fixes the back stop, which is responsible for the accuracy of the cut, in a certain position. The shears are turned on/off using a pedal: after completing the technological operation, the operator releases the pedal and the drive stops in the required position. After this, it is possible to install the next workpiece to be processed into the working area of the scissors. There is also a push-button station for controlling the scissors when they perform the hole-punching operation.
The range of application of the equipment under consideration can be expanded by installing a non-drive modular roller conveyor type MRP. In particular, it is possible to cut rods of round or square cross-section with a length of up to 3...6 m. The supplied basic set of tools and accessories includes:
The combined lubrication system used provides for the operation of the shears both inside and outside the production premises, and there is no need to supply compressed air to the installation site of the shears. The passport contains the necessary information about installing the scissors on a permanent basis, and the conditions for their shelter from adverse atmospheric influences.
To get a consultation
Combined shear presses NG5222 with a nominal force of 40 tf with a mechanical drive are used for cutting strip, long and shaped rolled products and punching holes in sheet, strip and shaped rolled products.
Having four working zones, the shear press allows you to perform multiple operations without changing tools or in any sequence.
Combined shear presses can find their application in engineering, repair and other factories, in commercial production and repair sites, and construction organizations.
Press shears NG5222 of our production have been supplied to the Central Federal District, Northwestern Federal District, Southern Federal District, North Caucasian Federal District, Volga Federal District, Ural Federal District, Siberian Federal District and CIS countries.

Four main mechanisms and work execution:
Kinematic diagram
1 – gear shaft, 2 – flywheel, 3 – electric motor, 4 – gear wheel,
5 – connecting rod, 6 – shaft, 7 – balancer, 8 – press slide, 9 – electromagnet,
10 – slider of the strip section.
The shear press is driven from an electric motor (3) through a V-belt transmission, a flywheel (2) and a single-stage gear transmission (1, 4) to an eccentric shaft (6). The gear pair (1.4) is straight-toothed, cylindrical. The movement is transmitted to the slider (10) of the strip section through the connecting rod (5), to the slider (8) of the press for punching holes through the balancer (7) and the sinking stone. Switching on and off the actuators is carried out through a system of levers connected on one side with a connecting rod and a sinking stone, and on the other hand with electromagnets (9).
Place the switch in the position: “band strip section” or in the “hole-punching section” position.
Attach the punch and die in the corresponding slots. Then, turning the centering mechanism handle, lower the punch into the die and insert the die holder body so that a uniform gap is maintained between the die and the punch.
Attach the die holder body to the frame and check the gap again.
Depending on the thickness of the material being punched, align the puller body by loosening the nuts and locknuts, and by rotating the screws, insert the puller body with a gap of 1...2 mm from the plane of the sheet.
Tighten the nuts and locknuts. Installing the puller body skewed is not permissible.
To punch holes along the cores, use the centering mechanism. Lower the punch with the handle and align the core on the workpiece with the punch core.
To cut shaped steel, install the appropriate tool in the socket of the slider and frame. Align the stop plate to the appropriate angle (90°, 45°) along the guide lines and secure it. Install replacement clamps. Insert the rolled piece into the tool socket and align it either according to the markings or against the cutting stop of the workpieces, the size of which you have previously set. Do not cut a strip that has oil stains on its surface.
When the scoring device is operating, the gap between the knives is set by spacers under the supporting surfaces and depends on the thickness of the material being cut. The knives of the scoring device must fit snugly to the supporting surfaces, must be well secured and dry.
Blow compressed air into the frame cavity under the strip slide to remove accumulated scale or remove it with a scraper.
For safety, the shear presses are equipped with guards for all rotating parts of the scoring device and the hole-punching area.
