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。 In the forming process does not appear part of the fracture, the minimum material thinning rate optimization principles, the impact on the forming quality of the factors: blank size, die gap, die rounding, the depth of the process between the depth of the blank holder Form, etc. conducted a comprehensive analysis of the development of the blanking, drawing, punching → redrawing, pressing side → punching, flanging → pressure tendons, plastic multi-step forming process. The comparative analysis of the actual production parts and the simulation results show that the numerical simulation results are basically in line with the actual production.
