摘　　要：传统的齿轮成形为机加工而成,极大地浪费了材料,采用挤压工艺对齿轮的关键部位进行成形,可以改善金属的流向分布.针对结合齿轮的成形过程,利用UG软件构建三维模型,使用DEFORM有限元软件对结合齿轮的温挤压成形进行数值模拟,对单工步成形和多工步成形进行模拟,分析挤压件的充填效果和应变分布.通过对预成形件的结构和参数优化,控制变量的方法获得了无缺陷、低吨位的较优成形方案,得到了较优的挤压工艺方案.Traditional gear forming is machined,which wastes a lot of materials.In this paper,the extrusion process is used to form the key parts of the gear,which can improve the metal flow distribution.Aiming at the forming process of combined gear,it uses UG software to build a three-dimensional model,uses DEFORM finite element software to simulate the warm extrusion forming of combined gear,simulates the single step forming and multi-step forming,and analyzes the filling effect and strain distribution of extrusion parts.The structure,parameters and control variables of the preform are optimized,and the defect free,low tonnage forming and better extrusion process scheme are obtained.
