摘　　要：应用楔横轧技术生产齿轮轴,生产效率、材料利用率高且强度得到提高。笔者应用Deform软件对楔横轧齿轮轴成形过程进行数值模拟研究,针对成形过程中出现的齿形不饱满和塌边现象进行了机理分析并提出了相应的模具设计和工艺参数的改进方案。数值模拟实验表明齿形不饱满和塌边现象得到了圆满解决。Application of cross wedge rolling technology production gear shaft is high efficiency, low material waste and high intensity. In this paper, numerical simulation on the process of gear shaft formed by cross wedge roiling was carried out with the help of SolidWorks and deform 3-d; To resolve the defects of disorder of tooth and edge collapse, Paper analyses the forming mechanism and designs the corresponding mold and improves process parameters. Numerical simulations show that the above defects have been satisfactorily resolved
