摘　　要：通过分析曲臂的结构特点和工艺特性,采用了一坯两件调头锻的工艺方案,详细介绍了曲臂锻模的结构、模具各个结构的具体设计、锻模材料的选取及热处理要求。该模锻工艺每小时可以生产120个锻件,生产效率高且曲臂的锻造精度高。模具增加.了切断型槽,可以节省20%的原材料,使锻件的成本降低了15个百分点。By analyzing the structural characteristics and processing characteristics of the crank arm,the processing scheme of one blank and two turning forgings was adopted.The overall structure of forging die,the specific design of each structure of the die,the selection of forging die material and the requirement of heat treatment were introduced in detail.The process can produce 120 forgings of crank arms per hour with high production efficiency and high forging precision.The cutting groove was added to the die,which can save 20%of raw materials and reduce the cost of forgings by 15%.
