[0002] Stamping dies are special process equipment used in cold stamping to process materials (metal or non-metal) into parts (or semi-finished products). Stamping cutting dies are stamping dies with added cutting structures, which can achieve the function of cutting while stamping. They are devices that can use the force of stamping and the cutting die to cut sheet metal.

[0003] A search revealed a stamping and cutting die in patent document CN 218252393 U, which uses a hydraulic cylinder to drive the upper die downwards for stamping. Although stamping and cutting can be achieved, the hydraulic cylinder's extension and retraction are slow, which is not conducive to continuous stamping processing. Therefore, a new stamping and cutting die is proposed to optimize the above-mentioned prior art. Utility Model Content
