Abstract：

The side-frame outer panel is the core outer covering parts of vehicle, which has characteristics such as complex shape，various processes, high surface quality and size precision of parts. After analyzing the stamping plans of the side-frame outer panel, the side sizing process and structure with double blank holders were put forward to solve the wrinkle and springback effectively and guarantee its quality. The design features and working principle of side sizing die mechanism with double blank holders were emphasized，and the compact and reasonable structure design of side sizing die for side-frame outer panel was accomplished. The actual production shows that the side sizing die can solve the wrinkling and springback during side sizing process, improve the forming quality and A-side quality，and reduce the design cost and development time.
