Considering the problems of spurgear precise plastic forming, such as high deformation resistance, poor flowability and especial hardness to fill cant of gear, technological plan was developed based on precise plastic forming technique, successive control principle and consecutive local deformation theory. Moreover, structures of the rolling preform die and the die with up and down wellrounded forcer for stamping-extrusion and bulge-extrusion combining forming were designed too.

因此本文的主要研究内容和结果如下：本文以某种直齿轮：模数m＝2，齿数z＝20，压力角α＝200，变位系数x＝0为对象，针对直齿轮精密塑性成形变形抗力大，流动性差，特别是成形中齿轮角隅部分更加难以充满问题，基于精密塑性成形技术、逐次控制原理以及连续局部变形原理提出了"直齿轮滚轧制坯－镦挤、胀挤复合精成形"的工艺方案，设计了滚轧制坯的模具结构和上下冲头带圆角的镦挤、胀挤复合精成形的模具结构。
