摘要
设计了发动机油底壳拉深工艺,确定为2次拉深成形。进行了模具总装配分析,确定了工作过程。建立了油底壳拉深的有限元模型,对工艺过程进行了仿真。通过改进模具结构及拉深工艺,使成形性能得到了改善。
The drawing process of engine oil pan was designed. And 2 times of drawing forming were determined. The final assembly of the die was analyzed. The working process was determined. The finite element model of the oil pan drawing was established. And the process was simulated. Through improving the die structure and drawing process, the forming performance was improved.
