摘　　要： 以在成形过程中零件不出现破裂、材料变薄率最小为优化原则,对影响成形质量的因素:坯料尺寸、模具间隙、入模圆角、各工序之间的拉深深度、压边圈的形式等进行了全面分析,制定了落料、拉深、冲孔→再拉深、压方→冲孔、翻边→压筋、整形的多工步成形工艺方案。实际生产零件与模拟的结果对比分析表明,数值模拟结果与实际生产基本相符。 Based on the optimization principles, which were that the parts were not be broken in the whole forming process and the material thinning rate was minimal, the factors which affect the forming quality, such as blank size, die clearance, punch round, the depth of drawing and the shape of binder, were analyzed. The forming processes of firstly blanking, drawing and punching, secondly drawing again and square cut, and then punching and rolling, finally pressing rib and shaping were defined. By comparing the actual production part with the simulation results, it can conclude that the numerical simulation results fit with the actual production.
