摘　　要：针对大导程滚珠丝杠副螺母内滚道难磨削技术缺陷,提出了一种冷挤压加工大导程螺母内滚道的成形方法。同时,基于切削-挤压复合理论学习基础上设计了一种新型加工螺母内滚道刀具。基于对挤压刀具设计,本文在有限元分析软件DEFORM-3D中进行了仿真加工分析。Aiming at the defects of the difficult grinding of the inner guide of the large lead ball screw nut, a forming method of the inner race of the large lead nut in cold extrusion is proposed. At the same time, based on the theory of cutting-extrusion compounding, a new type of machining nut internal rolling tool is designed. Based on the design of extrusion tool, the simulation processing analysis is carried out in the finite element analysis software DEFORM-3D.
