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。

Hexagonal bolts are usually formed with cold heading. The process is classified as open-die forging and therefore its die design is less complicated. The mushroom-like head has to be sheared into hexagonal shape and the amount of the scrap is somehow significant especially for heading with short bolts or high alloy material. There is an increasing demand in increasing the gross profit by increasing the yield of workpiece material.

六角螺栓头端通常以冷间顶铁成形製程来製造，由於冷间顶铁属於开模锻造，模具设计较容易，但需以剪缘模再对蕈状头端冲剪成为六角头，此剪缘后的废料量不容忽视，尤其对於长度较小的螺栓，或其它应用於紧扣件的高级合金而言，藉由减少废料以提高產品毛利的需求日益迫切。
