[0002] The stamping process is a technology that processes metal or non-metal materials into parts or semi-finished products of various shapes and sizes. During the stamping process, the mold is installed on the press. The pressure of the press causes the material to separate or plastically deform, thereby obtaining the required parts. Compared with traditional mechanical processing, the stamping process saves materials and energy, has high efficiency, does not require high technical skills from the operator, and can produce products that cannot be achieved by mechanical processing through the application of various molds. Therefore, its uses are becoming more and more extensive, and its application range in various industries is also extremely wide.

[0003] During the processing of automobile parts, some automobile parts are punched into the required shape by placing metal sheets on stamping dies through stamping devices. Stamped automobile parts have the characteristics of low manufacturing cost, high production efficiency, stable product quality, high material utilization rate, etc. The use of stamping devices can improve the efficiency of automobile parts processing.
