摘　　要：对现有C70型敞车枕梁下盖板冲孔冲角模具中的问题及产生问题的原因进行了分析。采用局部卸料板、聚氨酯弹簧托料、冲断斜刃、增加限位套等方式方法对模具进行了结构优化。通过批量生产验证结果表明,优化结构后的模具降低了操作人员的更换凸模的劳动强度,消除了更换凸模过程中存在的安全隐患和料边飞溅伤人现象,解决了现有模具中存在的问题,取得了良好效果,大大改善了操作人员的生产环境,并为后续此类模具设计提供了技术参考。This paper analyze the problems and causes of the existing punching hole andattacking angle die of body bolster under cover plate of C70 open wagon. Optimize die structureby methods of using local stripper plate, polyurethane spring used on holding marginal material,oblique blanking and increasing the limit set. The mass results show that the optimized reducesthe replacement of punches of labor intensity of the operators, eliminates the hidden securityrisks in the process of replacement of punches and the wounding phenomenon caused bysplashing marginal material, solves the problems of the existing die, achieves the good effect,greatly improves the production environment of operators, and provides technical reference forthe follow-up die design.
