The specific contents are as follows:

[0018] 1. The square hole punch body is pinned to the stamping machine through the pin hole. During the up and down reciprocating stamping process, it contacts the metal material, causing the material to be cut, and the parts required for the dust collector equipment are stamped out. In the previous stamping process, the blank material would always be lifted up by the punch or flanging, seriously affecting the production work. Therefore, a square hole punch with a pointed surface between the punch and the material is designed. In this way, at the moment of stamping, the tip contacts the metal material first, and then the edge of the punch cuts the metal material. The difference between the tip contact and the edge cutting is almost milliseconds, which will not affect the cutting effect and product quality. In this way, there will be a cavity between the blank material and the punch, and no adsorption will occur. It will fall directly into the blanking trough, preventing the blank material from being lifted up and flanging. This solves the problems in the actual production process, improves production efficiency, reduces production costs, and ensures production safety.

[0019] 2. A demoulding assembly is provided on the top of the square hole punch body. When the workpiece is stamped on the square hole punch body, the top plate can be driven to move, so that the top plate is inserted into the mounting groove, and the fixing ring is inserted into the circular groove. When the top plate moves, the telescopic spring on the mounting seat can be compressed, and the telescopic rod can be compressed. The top plate can drive the rubber ring on the mounting seat to squeeze the mounting ring, which can buffer the movement of the top plate. After the stamping of the workpiece is completed, the telescopic spring recovers its deformation, and the top plate can be positioned to facilitate the removal of the workpiece. When the workpiece is disassembled , rotate the top plate clockwise so that the column block on the connecting block slides on the L-shaped groove, so that the mounting block slides in the mounting slide rail. When the column block moves to the corner of the L-shaped groove, the mounting block is separated from the mounting slide rail. Lift the top plate so that the top plate can be removed. When installing the top plate, insert the column block into the L-shaped groove, rotate the top plate counterclockwise so that the column block can be inserted into the L-shaped groove, and the mounting block is inserted into the mounting slide rail to complete the installation of the top plate. The demoulding assembly facilitates the demoulding of the workpiece after stamping, and facilitates the removal of the workpiece, thereby improving practicality.

[0020] 3. After the top plate is removed, the movable sleeve can be pulled to squeeze the reset spring, so that the limit block on the movable sleeve is disengaged from the limit groove on the positioning block, and the rotating rod is rotated to stagger the limit block and the limit groove, and then the mounting seat can be removed, and the telescopic spring inside the mounting seat can be replaced to avoid fatigue of the telescopic spring caused by long-term use and affecting use. When installing the mounting seat, insert the mounting seat into the connecting groove, pull the movable sleeve and rotate it to align the limit block with the limit groove, and then release the movable sleeve to engage the limit block with the limit groove under the action of the reset spring, and then limit the mounting seat to complete the installation of the mounting seat, which is convenient for users to disassemble and assemble the mounting seat and replace the telescopic spring, and avoid fatigue of the telescopic spring caused by long-term use and affecting the reset of the top plate.
