自动脱模的卷圆件弯曲模设计

Design of Bending Die for Scrolling Round Parts with Automatic Stripping

在卷圆件成形过程中,为避免成形工具与冲压件发生干涉,采用在一副成形弯曲模上连续两次成形的方法,首先当凸模下行与活动凹模上升时,将毛坯件弯成U形;然后两个凹模滑块侧向水平向内形成两侧半圆形形状,并能使冲压件进行自动脱料。

In the course of the scrolling round parts forming, adopting the method that continue forming twice in a bend mold in order to avoid intervening between tool and bender. Firstly, the blank is bended for the U shape by the moving die and punch; secondly, two scrolling rounds are formed while two dies are moving to the inside. Then a level side slide block is designed, it can make the forming part able to automatically stripping.
