Abstract：

For the example of an auto cover part, its stamping process was studied and six processes including drawing, trimming- piercing, trimming, second trimming-piercing, flanging-sizing, side piercing and cutting were determined. In the first process, two parts were combined and drew. The forming precision and surface quality of this combined part were improved, and its producing efficiency was increased. Then its die was designed. Triming-piercing as well as trimming processes were conducted in the same die. Second trimming-piercing, flanging-sizing, side piercing and cutting processes were set in the same die too, namely, the compound stamping die with multi-position was adopted. Therefore, it reduces the quantity of dies, and the number of forming devices and workers needed reduces accordingly. As a result, the producing efficiency is improved and its cost is saved.
