Description

Technical Field

[0001] This utility model relates to the field of stamping, specifically to a stamping forming apparatus for automotive parts. Background Technology

[0002] Stamping of automotive parts refers to the process of cutting a roll of steel sheet and then stamping it into the required shape in one or more passes using a die, either in a cold or hot state. The parts then undergo trimming, punching, shaping, and inspection to ultimately produce dimensionally accurate parts that meet strength standards. Different stamping dies are required for each type of part.

[0003] Patent CN220862530U describes a self-centering stamping die, including an upper die and a lower die. The upper die includes an upper die fixing seat, an upper die base, an internal forming punch, and a pair of T-shaped guide pillars. The upper die base is provided with an outline forming punch, which has a through hole. The lower die includes a lower die fixing seat. The lower die fixing seat is provided with a fixing plate. A longitudinal guide pillar is provided between the fixing plates. A movable plate is provided on the longitudinal guide pillar. A transverse guide pillar is provided between the movable plates. A lower die base is provided on the transverse guide pillar. The lower die base is provided with a forming groove. A forming hole is provided at the bottom of the forming groove. A scrap hole is provided on the lower die fixing seat.

[0004] The self-centering stamping die has a set of T-slots on its worktable for mounting the lower die holder. However, during use, it was found that the T-slot mounting of the lower die holder can be unstable. For example, after the lower die holder is tightened, it may shift along the direction of the T-slot. This can cause the upper and lower dies to shift, affecting normal stamping.
