摘　　要：GH4169材料强度高、切削性能差,在滚压螺纹过程中,滚丝轮的使用寿命急剧下降,甚至报废,严重影响生产,且螺纹加工精度低。针对该问题进行分析,通过对加工前的滚压参数进行选择及滚坯工艺结构的确定,提高了滚丝轮的使用寿命及螺纹加工精度。The material GH4169 has high strength and poor cutting performance.In the process of rolling thread,the service life of the rolling dies drops sharply,even it is discarded,which seriously affects the production,and the thread processing accuracy is low.In order to improve the service life and thread machining accuracy of the rolling dies,the rolling parameters before machining and the technological structure of the rolling blank are selected.
