摘　　要：汽车差速器齿轮冷挤压成形技术的关键是冷挤压模具的设计与制造。齿轮冷挤压模具设计已得到较为广泛的研究,但制造方面较少被提及。针对冷挤压模具制造现状,提出一种高速铣削加工方案。为解决模具铣削中材料硬度高、刀具磨损和让刀量大等问题,基于DEFORM-3D仿真软件,设计单因素仿真试验进行对比分析,合理分配加工余量,并优选出切削力较小、刀具磨损程度低的切削用量。该方法为研究冷挤压类模具加工工艺提供了思路。The key to cold extrusion forming technology for automotive differential gears is the design and manufacturing of cold extrusion molds.The design of gear cold extrusion molds has been extensively studied,but manufacturing is rarely mentioned.This article proposes a high-speed milling processing plan for the current status of cold extrusion mold manufacturing.In order to solve the problems of high hardness,tool wear and large tool yield in mold milling,a single factor simulation test is designed based on DEFORM-3D simulation software.Through comparative analysis,the machining allowance is reasonably allocated,and the cutting parameters with small cutting force and low tool wear are selected.The method proposed in this article provides ideas for studying the processing technology of cold extrusion molds.
