摘　　要：基于钢杯套结构设计了杯套的挤压模具,并对杯套的挤压成型工艺参数进行分析,基于DEFORM软件进行成型方案仿真,仿真结果表明成型方案可行,锻件发生锻造折叠、裂纹等缺陷的概率低,模具可靠有效应力约为800MPa,处于合理范围之内。基于Archard磨损模型,得到单次最大磨损深度及分布区域,并进一步分析了模具磨损影响因子,得出滑移速率是影响模具磨损的最主要因素的结论,为下一步成型工艺方案的优化及模具寿命预测奠定可行性基础,并为产品生产提供理论支撑。According to the structure of the steel cup sleeve,the extrusion die of the cup sleeve is designed,and the extrusion process parameters of the cup sleeve are analyzed.The forming scheme is simulated based on DEFORM software.The simulation results show that the forming scheme is feasible,the probability of forging folding,cracks and other defects is low,and the effective stress of the die is about 800MPa,which is in a reasonable range.Based on the Archard wear model,the single maximum wear depth and distribution area are obtained,and the influence factors of die wear are further analyzed.It is concluded that the slip rate is the most important factor affecting the die wear,which lays a feasible foundation for the optimization of subsequent molding process and the prediction of die life,and provides theoretical support for product production.
