Abstract：

The Autoform simulation software has been widely used in the automotive field, but sometimes the simulation results and the actual production results are different. Therefore, in order to solve the problems of production and cost reduction for a certain type of rearview mirror reinforcement plate for commercial vehicle, the existing die was reformed combining with CAE analysis results and field experiments, and the process reforming scheme of part was determined to change from drawing to blanking. The results show that the material utilization ratio of part is increased by 47.3%, and the production problems for “hardening mark” of part and “breaking edge” of trimming edges are solved. It is finally confirmed that for multi-material flanging mild steel parts with low trimming quality requirements, the blanking process can still be considered for layout production, even if it′s not supported by the CAE simulation results.
