At present, the materials that can be stamped are not only low-carbon steel, but also stainless steel, aluminum and aluminum alloys, copper and copper alloys, etc. These metals usually have good mechanical properties and large deformation capabilities. When stamping, these metals usually need to be heated before they can be processed, and then they need to be stamped or punched multiple times to get the desired workpiece.

[0003] In the process of continuous practice, researchers have found that these metals often suffer damage and tearing during stamping, which is usually caused by the nature of the metal itself, greatly reducing the yield rate. The use of sheet metal will only increase the error of the product and make the product unusable. Therefore, a device is needed that can punch and punch the workpiece while reducing the impact on the workpiece itself and not destroying the accuracy of the workpiece. Summary of the invention
