[0002] A punch refers to a metal part on a stamping die in a mechanical tool. The punch is also called a punch rod, a needle or a punch. The punch is a part installed on a stamping die for continuous blanking and stamping work. A special-shaped punch refers to a punch whose impact position is a strange shape, so that the punched hole is formed into the required type. The working process of the punch is that the stamping die applies pressure to the punch, allowing the top of the punch to perform a high-intensity impact on the inside of the processed material, so that the inside of the stamped material is punched.

[0003] After the existing special-shaped punch rods have been used for a certain period of time, their surfaces will wear out, resulting in loss. At this time, the old special-shaped punch rods need to be removed and replaced with new special-shaped punch rods for subsequent use by personnel. The existing special-shaped punch rods are more inconvenient to disassemble and assemble. Personnel may need to use tools to remove multiple bolts, nuts and other parts before they can disassemble and replace the special-shaped punch rods. During this period, the disassembly and assembly time of the special-shaped punch rods may be increased, and the disassembly and assembly efficiency of the special-shaped punch rods may be reduced.
