摘　　要：在冷镦生产中 ,当零件的头部变形较大时 ,通常采用大料及缩径的加工方法。使用该方法冷镦凹模寿命低。通过理论分析和大量的实验后 ,成功地采用双锥度锥形模加普通凹模的生产方式 ,生产头部变形较大的零件 ,取得了良好的效果 ,大大降低了零件的生产成本。In the cold upsetting production,when the head of the part deforms much,a big block would generally be used and the diameter reducing processing method adopted.The cold upsetting matrix's life is relatively short in this way.Through theoretical analyses and a great many of experiments,the part with the head deforming much was successfully produced by adopting the bisconical die and common matrix,and the part cost was greatly lowered.
