The movement to the slider (10) of the strip section is transmitted through the connecting rod (5), to the slider (8) of the punching press through the balance bar (7) and the sinking stone. Turning on and off the actuators is carried out through a system of levers connected on the one hand with the connecting rod and the sinking stone, and on the other hand with electromagnets (9).
Set the switch to the position: "strip section" or to the "perforating section" position.
- Hole punching:
Fix the punch and the matrix in the appropriate sockets. Then, turning the handle of the centering mechanism, lower the punch into the die and insert the die holder body so that a uniform gap between the die and the punch is maintained.
Attach the die holder body to the bed and check the gap again.
Depending on the thickness of the punched material, expose the puller body, for which loosen the nuts and locknuts, and, turning the screws, insert the puller body with a gap of 1 ... 2 mm from the sheet plane.
Tighten nuts and locknuts. Installing the puller body with a skew is not allowed.
Use the centering mechanism to punch hole punches. Lower the punch with the handle and align the punch on the workpiece with the punch core.
- Strip section:
To cut shaped steel, install the appropriate tool in the slot of the slider and bed. Align the stop plate to the appropriate angle (90°, 45°) according to the grooves of the guide and fix it. Install replacement clamps. Enter the rolled metal into the tool socket and set it either according to the markup or at the cutting stop of the workpieces, the size of which is pre-set. Do not cut a strip that has oil stains on its surface.
During the operation of the notching device, 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 notching device must fit snugly against the supporting surfaces, must be well fixed and dry.
Blow out the bed cavity under the section slider with compressed air to remove accumulated scale or remove with a scraper.

The lineup |
Combined press scissors ng5222 is a machine manufactured by the Kuvandyk Dolina plant. The company itself was founded in 1941. Since then, the company has been providing customers with high-precision equipment with excellent technical and operational characteristics.
Photo press scissors
Press scissors nv5222 are used to perform high-quality cutting of rolled products - shaped, sheet, high-quality. Also, the devices allow you to make various notches.
Combination shears may be called press shears provided they are equipped with a punch press.
The technical characteristics of the NG5222 model provide for the presence of four mechanisms that form the basis of the equipment:
- The mechanism of cutting high-quality metals;
- For cutting metal sheet;
- Hole making system;
- Grooving device.
What you need to know about similar press scissors combined models NG5222?
- All of these mechanisms are assembled in a single frame, equipped with a common drive.
- The sliders of the sheet shear use a lever mechanism for control.
- The punching mechanism of the device has two types of control - lever and pedal.
- The main technical characteristics are regulated by the state standard.
- Shear cutting is the most cost-effective way of separating rolled stock into the appropriate required blanks.
- When working with a cutter, it is important to avoid a double cut. To do this, it is required to observe a certain depth of entry of knives into the metal workpiece. It should not exceed V4 from the height of the cut section. This is especially important when processing ductile metal or workpieces that have been specially heated to a high temperature.
- To prevent the formation of cracks on the end sides of the workpieces being processed, which may be due to the brittleness of certain steel grades, the workpiece should be heated.
- The cold method cuts carbon steel, the percentage of carbon in which does not exceed 0.5 percent.
- The resulting quality of the workpiece cut is directly affected by the speed of the knife entering the metal. If cutting of carbon steel is required, higher speeds are used. Alloy steel requires more delicate cutting, so the speed is reduced.
- Based on the characteristics of processing different types of metals, it is reasonable to equip the press machine with two-speed electric motors in order to control and regulate the speed of work.
Features of the machine NG5222
Among the combined press shears on the market, the combined devices of the new generation have won the greatest popularity. Model NG5222 provides solutions to many production issues.
