The utility model relates to the technical field of stamping dies, in particular to a stamping die of a split structure automobile rear cross beam sheet piece.

Background technique

Stamping die is a special process equipment that processes materials (metal or non-metal) into parts (or semi-finished products) in cold stamping, called cold stamping die (commonly known as cold stamping die). The die installed on the press exerts pressure on the material, causing it to separate or plastically deform, so as to obtain the desired part, a pressure processing method, but the existing split structure automobile rear beam sheet metal stamping die cannot be used for the rear beam sheet. Parts are limited, which leads to the easy deviation of the rear beam sheet during the compression process, which affects the stability and reduces its stamping accuracy. To this end, we propose a stamping die for a split-structure automobile rear beam sheet.
