Abstract：

For the problems of crack and wrinkle existing in the stamping forming process of front beam connecting part for automobile, the stamping process scheme of front beam connecting part was optimized by CAE analysis and debugging method to ensure the successfully forming of products. Based on the comparative analysis of CAE technology and stamping products, it shows that the reasonable design of binder shape can control the local material flow uniformity in the forming process of product to ensure the quality of stamping parts, and the problem of forming crack can be effectively solved by adjusting the depth of drawing and sizing reasonably with drawing depth of 68 mm and the sizing depth of 10 mm. Therefore, the closer the parting line is to the product, the more effective it is to control the flow of sheet, and it can reduce the forming wrinkling risk, increase the material utilization rate and increase the blankholder force. Furthermore, the side wall of front beam connecting part is prone to wrinkle, which cannot be completely solved by technological means, and it is necessary to adjust the product structure to a certain extent.
