摘要：

研究了带翻边拉深件的成形工艺，通过对零件结构的分析比较，确定了合理的成形工艺方案；采用Dynaform软件对拉深件的坯料尺寸进行估计，简化了计算过程，同时对拉深件的成形过程进行数值模拟分析，用初步的模拟结果验证了成形方案和工艺参数的合理性；设计拉深模具，通过生产试模，生产出了合格产品，对试模结果与模拟结果进行比较，得到了较好的一致性。

The forming process of the drawing part with flanging was researched, and the research results were analyzed and compared to determine the reasonable forming process scheme; the blank size of the drawing part was estimated by Dynaform software so that the calculation process was simplified, while numerical simulation analysis of the forming process for the drawing part was carried out and the rationality of the forming scheme and the process parameters were verified by preliminary simulation results; the drawing die was designed, the die was tested, and the qualified product was produced finally, the die-testing results were compared with the simulation results, and the good consistency was obtained. This method provides a practical reference value for the forming process of complex rotating drawing parts.
