   Nowadays, the demand for technological transformation of existing equipment according to products and rapid production is more urgent than ever before. In these technical work processes, a certain range of "specialized special components" is very beneficial. Among these so-called specialized special components, stamping molds and deformation processing molds are still important components of automotive stamping equipment and will still determine the stamping production process.

   The research and development of automatic stamping production lines, the mechanization transformation of stamping production lines, the manufacturing of large vacuum feeding stamping machines for automotive sidewall production, and the successful entry of small vacuum feeding stamping machines into the market are all successful examples of close cooperation between the automotive industry and stamping machine production enterprises.

   Therefore, valuable technological improvements and improvements are concentrated in the automated transportation and transmission devices of automotive stamping parts, as well as in the automation of stamping equipment loading and product oriented stamping production processes. The distinction between traditional stamping and automation concepts is a prerequisite for the flexibility of the stamping production process and the product oriented configuration of stamping equipment. According to the transmission system in stamping equipment, stamping equipment can be distinguished, for example, by comparing traditional cam driven mechanical transmission with swing arm transmission. In traditional cam driven stamping equipment, the control cam for stamping stroke is designed according to the stamping requirements of the workpiece. Regardless of the complexity of the workpiece being stamped, the stamping machine tool moves according to the prescribed stroke of the cam, which results in the same amount of work hours spent on stamping simple workpieces as on stamping complex workpieces.
