[0002] Sheet metal is a comprehensive cold processing technology for thin metal plates, including shearing, punching / cutting / compounding, folding, welding, riveting, splicing, forming, etc. Its most notable feature is that the thickness of the same part is consistent. The products processed by sheet metal technology are called sheet metal parts. The sheet metal parts referred to in different industries are generally different, and are mostly used for assembly. Metal parts are products processed by sheet metal technology. We cannot live without sheet metal parts everywhere in our lives. Sheet metal parts are made by filament power winding, laser cutting, heavy processing, metal bonding, metal drawing, plasma cutting, precision welding, roll forming, metal plate bending, die forging, and water jet cutting. When sheet metal parts are processed, punching operations are required.
[0003] For punching devices for sheet metal parts on the market, after punching, most of the sheet metal parts will have burrs and uneven areas on the holes due to the effect of stamping.
