Type of tensioners.

Active type of stamp. The lower part of the stamp is at the starting level of stamping. Two hydraulic cylinders press from the bottom with a force of approximately 20 bar. When the upper part of the stamp descends, it does so using hydraulic plungers, which press with a force of approximately 100 bar. The upper part of the stamp presses the metal against the lower part and, overcoming its resistance, presses the metal and the lower part of the stamp to the required depth. After that, the upper part of the stamp rises, the movement of the metal begins, and at this moment, the lower part of the stamp is lifted using hydraulic cylinders. Then the cycle repeats.

Adjustment of stamping depth. The depth is adjusted with the help of a 6 mm thick metal plate, which is slid under or out from the lower part of the stamp. The operation is done manually, by turning the handwheel.

Green arrows indicate how the metal sheet should fall. This means that after the cut, nothing should prevent the sheet from falling down onto the pallet.

The design of the shears should not hinder the finished sheet from falling down. This will allow the client to use a simple receiving table without a conveyor belt.

Active type cross-cutting shears. During stamp operation, the lower blade is in the down position and removed from the cutting area to prevent deformation of the metal around the blade during stamping. When it is necessary to make a cut, the lower blade is raised and fixed at the required level. The upper blade then makes the cut, after which the lower blade is lowered again. The cycle then repeats.

The location of the mold stamping mechanism and the metal cutting shears should be separate, but should be located as close to each other as possible.
