A Method by Fitting Two Points on the Curve of the Flank Profile of Trimming Dies for Bevel Gears

锥齿轮 锻件 切 边 模齿廓曲线二点拟合法

Based on the theoretical study the authors have developed a function-oriented CAD system of trimming and punching dies for panels .

基于这种设计方法，作者在UG平台开发了一套实用的 修 边 冲孔 模CAD系统。

A new type of structure of the trimming dies and the formulae for designing the cutting edge of the dies are put forward the manufacture process and the seriation of the dies are discussed .

提出新型 切 边 模结构和刃口齿形设计计算公式，论述模具制造工艺、模块翻新和模具系列化方案。

In virtue of the unreasonable structure and backward manufacture processes of the cutting edge of the die blocks the life of the former trimming dies for forged bevel gears is short and trimming quality is poor .

锥齿轮锻件原 切 边 模结构不尽合理，模块刃口加工方法落后，模具寿命低、切边质量差。
