Abstract：

Traditional production of stamping part that one die can only be used for one part with defects, such as large development costs, long produce cycle, and the change of different dies for various parts leading to low efficiency in production. According to the similar characteristics of decoil blanking die of inner and outer plates of automobile engine hood parts, an universal decoil blanking die structure for multiple car models was designed and manufactured. The design keys of the blanking die were analyzed. The designed and manufactured blanking die was successfully applied to multiple projects in an enterprise. The results show that the blanking die and its structure can effectively reduce development costs and cycle of the die, and realize the continuous production without changing the die, save set-up time and further improve the productivity.
