针对杯形件温挤生产中挤压凸模寿命过低这一问题 ,从分析导致该问题的主要因素入手 ,对现行工艺中挤压凸模的润滑方式进行了改进 ,并对改进方式进行了计算机模拟分析和实验验证。结果表明 :采用改进润滑方式后 ,挤压力约降低 30 % ,挤压凸模的温升下降 15 %左右 ,从而有效地改善了凸模的工作条件 ,实现挤压凸模寿命的提高 Aiming at the problem that the extrusion punch’s life is too low in the cup extrusion production, this paper analyzes the main factors leading to this problem, and improves the lubrication mode of the extrusion punch in the current process, Computer simulation analysis and experimental verification. The results show that the extrusion pressure is reduced by about 30% and the temperature rise of the extrusion die is reduced by about 15% with the improved lubrication method, thereby effectively improving the working conditions of the punch and increasing the life of the extrusion die
