摘要：

Autoform仿真软件已经被广泛应用于汽车领域，但仿真结果和实际生产结果不同的情况亦有发生。以解决某型商用车后视镜加强板生产和降低成本的问题为例，在现有模具的基础上进行改造，结合CAE分析结果和现场实验，确定零件工艺整改方案由拉延成形工艺改为落料成形工艺。结果表明：该零件材料利用率提升了47.3%，并解决了零件“硬化痕”和修边刃口“崩刃”的生产问题。最终证实，针对修边质量要求不高的多料翻边软钢材质零件，在CAE模拟结果不支持落料成形工艺方案的情况下，依然可以考虑采用落料成形工艺进行排布生产。

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.
