锻模的燕尾形部位是用来装夹于模锻机上定位和固定的重要部位.我们的大中型锻模燕尾部分,过去的加工方法是:在龙门刨床上加工好毛胚后卸下机床,将模块放置于平板上,用游标高度划线尺划出如图1所示的B/2中心线和燕尾形的大端L尺寸线,划后将模块转90°划H尺寸线,然后用角度尺和圆规分别划出α角斜线及R半圆弧线,划线后再装夹于龙门刨,校正原基准面后才加工燕尾形状.如此加工方法工作效率较低,也很麻烦.为了提高生产效率减少重复装夹和减轻劳动强度,我们将锻模燕尾形的加工方法进行了改进,并设计制造了如图2所示的锻模燕尾划线卡.
Forging the dovetail parts is used to clamp the positioning and fixing of the die forging an important part of our large and medium-sized swage dovetail part of the past processing methods are: in the planer processing rough blank after the removal of machine tools, Place the module on a flatbed and draw the B / 2 centerline and the dovetail large-end L dimension line as shown in Figure 1 with the wiper height scriber and slide the module 90 ° to the H-dimension line and use Angle ruler and compasses, respectively, out of alpha angle and R semicircle arc line, scribed and then mounted on the planer, the correction of the original datum before processing dovetail shape.This method of working less efficient, but also a lot of trouble.In order to Improve production efficiency Reduce duplication of clamping and reduce labor intensity, we have forging dovetail processing methods have been improved, and designed and manufactured as shown in Figure 2 forging swage dove tail card.
