Abstract

本实用新型涉及一种U形摆动折弯模,由凸模,顶料板和凹模摆动块组成,顶料板的背部为有一定斜度的斜面,顶料板两侧设有相应的两个凹模摆动块,凹模摆动块在面向顶料板的一面的底部为突出斜面,利用顶料板背部斜面和凹模摆动块的突出斜面相互作用,使凹模向内摆动,从而使产品产生负角,消除回弹。该模具结构简单可靠,制造工艺要求不高,适用批量生产。

Description

U形摆动折弯模
技术领域
本实用新型涉及一种U形摆动折弯模。
背景技术
目前现有的技术中,制造两端为U形折弯的金属弹片,当两角角度较大时,折弯角度回弹不好控制,对于如何消除回弹的设计是我们所迫切需要的。
发明内容
本实用新型的目的在于提供一种结构简单可靠,制造工艺要求不高的U形摆动折弯模。
U形摆动折弯模,包括凸模,顶料板和凹模摆动块,顶料板的背部为有一定斜度的斜面,顶料板两侧设有相应的两个凹模摆动块,凹模摆动块在面向顶料板的一面的底部为突出斜面。
本实用新型的优点:该模具结构简单可靠,制造工艺要求不高,适用批量生产,可以应用于类似U形折弯产品,改变传统U形摆动弯曲模制造困难的现象。
附图说明
图1为本实用新型结构示意图。
具体实施方案
本实用新型的一种较佳实施例:
如图1所示,
U形摆动折弯模,由凸模(3),顶料板(1)和凹模摆动块(4)组成,顶料板(1)的背部为有一定斜度的斜面,顶料板(1)两侧设有相应的两个凹模摆动块(4),凹模摆动块(4)在面向顶料板(1)的一面的底部为突出斜面,利用顶料板(1)背部斜面和凹模摆动块(4)的突出斜面相互作用,使凹模向内摆动,从而使产品产生负角,消除回弹。
工作时,压力机滑块下移,凸模(3)接触产品(2)随之压紧顶料板(1)向下运动,当顶料板(1)底部斜面与凹模摆动块(4)斜面接触,使凹模摆动块(4)向内摆动一定角度,上模上行顶料板(1)在顶料弹簧作用下推出工件(2)并使凹模摆动块(4)回位,完成一个过程。
以上所述仅为本实用新型的较佳实施例,凡依本实用新型申请专利范围所做的均等变化与修饰,皆应属于本实用新型的涵盖范围。
