The combined punching shear machine is widely used in steel structure processing and production, high voltage wire tower, telecommunication tower, street lamp, advertisement, shelf, elevator, ventilation pipe and other civil facilities production enterprises; and can be used in large steel bridge, military, aerospace and other high requirements, high precision production and construction, is a kind of metal material manual shearing, cutting. And punching and processing machinery and equipment.

The combined punching machine uses overlapping two levers and sliders to drive the sliding plate with three kinds of cutting edges up and down, and the fixed edge installed on the frame to complete the cutting and blanking process. The utility model combined punching and shearing machine has the advantages of compact structure, small volume, light weight, convenient operation, can cut round and angle steel, can cut sheet metal, can also punch and cut. It is an ideal multi-functional manual shearing machine at present.

The punch head of the punch shearing machine is fixed at the lower end of the piston rod of the cylinder with the locking nut, and the lower die is supported in the mold seat fixed on the bed with the bolt. When the punch and the lower die are on time, tighten the bolts. In order to punch and cut square holes and long round holes, besides the piston rod with side plane guide, a long circular positioning groove is milled on the connecting body of the punch die to prevent the punch from turning or shifting, and other dies are installed on this station, which can also be used for bending, pipe die shearing, shutter punching, punching large holes, channel steel, I-beam, H-beam, and web punching. And so on.

The key technology of combined punching and shearing machine is mainly composed of two hydraulic workstations and five workstations.

1, punching function position: the stamping end is equipped with movable worktable, thus providing the application scope of punching. Changing the structure and shape of the stamping die can punch out the parts of various shapes needed, such as: punching the special-shaped slots and holes, sheet folding, punching shutters, can punch the flange of channel steel, I-beam.

2. Angle cutting function of angle steel: angle steel shear slice, both sides can be used. In order to reduce deformation, large angle steel is sheared, large rounded angle steel is used for movable sheet, small rounded angle steel is used for movable sheet. If the blade is not sharp, it can be turned or exchanged.

3. Section steel shearing function position: In the section steel shearing hole, with different can shear round steel, square steel, channel steel, I-beam, T-beam. It is easy and reliable to assemble and disassemble through a simple fixture.

4. Shearing Function Position: In addition to shearing sheets and strips, the angle of the angle steel or sheet can be trimmed (first, the size of the required workpiece is sheared into shape, and then the molding workpiece is placed in this position, the required angle can be sheared).

5. Mode shear work position: the die shear station can design punch with various grooves according to the shape requirements. Such as installation of rectangular, V groove. When slotting punch requires grinding, it can only repair the side and front of the punch.
