Description

A sheet metal forming mold

technical field

The utility model relates to the technical field of forming dies for sheet metal parts, in particular to a forming die for sheet metal parts.

Background technique

Sheet metal is a comprehensive cold working process for sheet metal, including shearing, punching/cutting/compositing, folding, welding, riveting, splicing, forming (such as car body), etc. Its remarkable feature is that the thickness of the same part is consistent. The products processed by the sheet metal process are called sheet metal parts. When producing sheet metal parts, molds are needed. Sheet metal forming molds generally include moving molds and fixed molds.
