Abstract：

In order to solve the problems of low automation degree and high defect rate in the processing of automotive internal reinforcement parts, for a typical reinforcement part, the reasonable forming process scheme was formulated by analyzing the stamping process performance of parts, and according to symmetrical features of parts, the same two parts were processed in one die by taking the connection center line of two parts as symmetry axis. Furthermore, eighteen stations including blanking, bending, flanging, turning angle and side punching etc. were designed in the layout, and combined with the CAE simulation analysis of thinning rate and springback, the key points of multi-position progressive die design were described such as stiffener design, shock absorber design, wedge punching design, etc. The practice shows that the design scheme of die realizes the automatic production of automotive interior reinforcement and improves the production efficiency, and it has a strong guiding significance for the design and production of similar dies in enterprises.
