摘要：

根据某曲轴模具磨损，基于Archard磨损有限元理论，从模具磨损失效出发，针对影响模具磨损量的工艺参数，设计正交试验。采用Deform数值模拟，研究了工件初始温度、模具初始温度、工件与模具之间摩擦系数以及模具硬度对成形载荷和模具磨损的影响。优化了曲轴热模锻成形的工艺参数，综合考虑多指标因素，分析得到影响曲轴成形力和模具磨损量的最优工艺参数，即坯料初始温度为1150 ℃、模具初始温度为250 ℃、摩擦系数为0.3、模具硬度为65 HRC。

According to the wearing of one crankshaft mold and Archard wear finite element theory applied, the orthogonal experiment was designed starting point to die fracture and failure and aiming to the influence on process parameters of die wearing. The influence of initial temperature of blank and mold, friction coefficient between workpiece and its dies, and mold hardness on forming load and mold wearing were researched by numerical simulation based on Deform. The process parameters of hot die forging forming of crankshaft were optimized. Comprehensively considering the multi-index factors, the influence of optimal technological parameters on crankshaft forming force and mold wearing was obtained, that is the initial temperature of blank is 1150 ℃, initial mold temperature is 250 ℃, coefficient of friction is 0.3, and mold hardness is 65 HRC.
