Abstract

本实用新型公开了一种外法兰冲孔防变形装置,包括有切边上、下模、凹模、导柱、弹簧、切边冲头连接块和切边冲头,切边冲头的下端固定连接有防变形块,防变形块的形状与凹模的内腔形状相匹配。本实用新型结构简单,冲床带动切边上模和切边冲头向下动作,对产品进行冲裁,防变形块随之向下动作,能够有效抑制产品的收缩变形,大大提高了产品的合格率。

Description

外法兰冲孔防变形装置
技术领域
本实用新型涉及冲孔模具领域,具体是一种外法兰冲孔防变形装置。
背景技术
传统的外法兰冲孔模具没有装配切边防变形装置,外法兰一般外形皆是非圆的不规则形状,当终锻完成后,剪切飞边时因各边至圆心的热收缩比例不同,导致产品冷却后变形。
实用新型内容
本实用新型的目的是提供一种外法兰冲孔防变形装置,来抑制产品的收缩变形,以提高产品的合格率。
本实用新型的技术方案如下:
一种外法兰冲孔防变形装置,包括有切边上、下模、凹模、导柱、弹簧、切边冲头连接块和切边冲头,其特征在于:所述切边冲头的下端固定连接有防变形块,所述防变形块的形状与所述凹模的内腔形状相匹配。
所述的外法兰冲孔防变形装置,其特征在于:所述的防变形块采用金属块。
本实用新型的有益效果:
本实用新型结构简单,冲床带动切边上模和切边冲头向下动作,对产品进行冲裁,防变形块随之向下动作,能够有效抑制产品的收缩变形,大大提高了产品的合格率。
附图说明
图1为本实用新型结构示意图。
具体实施方式
参见图1,一种外法兰冲孔防变形装置,包括有切边上、下模1、2、凹模3、导柱、弹簧5、切边冲头连接块6和切边冲头7,切边冲头7的下端固定连接有防变形块4,防变形块4的形状与凹模3的内腔形状相匹配。
本实用新型中,防变形块4采用硬度好、刚性高的金属块。
