[0002] Sheet metal forming is a metal processing method that processes metal sheets into the desired shape under a certain temperature and pressure. The processes of sheet metal forming include shearing, stamping, bending, stretching, pressure forming, etc.

[0003] During the punching process of sheet metal, the upper and lower dies are usually used to press the sheet metal material and then punch it to prevent the sheet metal from slipping during the punching process, which affects the product quality. However, this is affected by factors such as the mold preparation accuracy and the thickness of the sheet metal. When processing some small batches of sheet metal parts, opening the mold greatly increases the processing cost. For this reason, we have designed a sheet metal edge clamping device for punching.
