[0002] Stamping is a processing method that uses a press and a die to apply external force to a material, causing it to separate or undergo plastic deformation to obtain parts of the desired shape and size. The punch, as a key component in the stamping die, is in direct contact with the formed part, performing blanking and stretching of the material. During the stamping process, the punch is subjected to long-term, high-frequency impact, shearing, and frictional forces, making it prone to failure modes such as plastic deformation, fracture, adhesive wear, and abrasive wear.

[0030] The above solution is adopted as follows: Two locking blocks 203 are symmetrically fixedly installed on the top of the periphery of the plug rod 201. The tops of the two locking blocks 203 are interference-fitted into the two corresponding slots 204 opened at the bottom of the inner wall of the docking slot 202, so as to achieve a stable connection and avoid the problem of the inner cooling punch 1 and the combined connecting block 3 detaching. The combined connecting structure 2 also includes docking plates 1 205 symmetrically fixed on the top of both ends of the inner cooling punch 1. Both ends of the combined connecting block 3 are fixedly installed with docking plates 206.
