Abstract

本实用新型涉及一种C形卡具成型模具，包括模具体，所述模具体的中心设有长方体形凹坑，该凹坑的两侧壁与模具体上表面的连接处为圆弧倒角，所述凹坑内设有底部带复位弹簧的顶料块；其创新点在于：所述模具体的圆弧倒角处嵌有圆柱形滚动体。本实用新型的优点在于：通过在圆弧倒角处前圆柱形滚动体，使得板材在被冲压成C形的时候，板材的折弯部分与圆柱形滚动体滚动摩擦，板材表面不易产生毛刺，成型后的卡具表面质量高，模具体也不易磨损。

Description

一种C形卡具成型模具
技术领域
本实用新型涉及一种成型模具，特别涉及一种C形卡具成型模具。 
背景技术
C形卡具用于馈线的接地、安装，其在制造时通过C形卡具成型模具冲压成型。传统的C形卡具成型模具包括模具体，所述模具体的中心设有长方体形凹坑，该凹坑的两侧壁与模具上表面的连接处为圆弧倒角，所述凹坑内设有底部带复位弹簧的顶料块。成型时，条形板材置于模具体的上表面，在压机压头的冲压下，板材的中部被冲入凹坑内，两端沿圆弧倒角滑动，使得整个板材形成C形。该种模具的缺点是：模具体的圆弧倒角处于板材滑动摩擦，板材与模具接触处易其毛刺，影响外表质量，且模具圆弧倒角易磨损，增加的制造成本。 
发明内容
本实用新型要解决的技术问题是提供一种模具和成型的工件均不易磨损的C形卡具成型模具。 
为解决上述技术问题，本实用新型的技术方案为：一种C形卡具成型模具，包括模具体，所述模具体的中心设有长方体形凹坑，该凹坑的两侧壁与模具体上表面的连接处为圆弧倒角，所述凹坑内设有底部带复位弹簧的顶料块；其创新点在于：所述模具体的圆弧倒角处嵌有圆柱形滚动体。 
本实用新型的优点在于：通过在圆弧倒角处前圆柱形滚动体，使得板材在被冲压成C形的时候，板材的折弯部分与圆柱形滚动体滚动摩擦，板材表面不易产生毛刺，成型后的卡具表面质量高，模具体也不易磨损。 
附图说明
附图1为本实用新型C形卡具成型模具结构示意图。 
具体实施方式
如附图所示，本实用新型涉及一种模具和成型的工件均不易磨损的C形卡具成型模具，包括模具体1，该模具体1的中心设有长方体形凹坑，该凹坑的两侧壁与模具体1上表面的连接处为圆弧倒角，凹坑内设有底部带复位弹簧的顶料块2；模具体1的圆弧倒角处表面开空腔，空腔内嵌有圆柱形滚动体3。板材在被冲压成C形的时候，板材的折弯部分与圆柱形滚动体3滚动摩擦，板材表面不易产生毛刺，成型后的卡具表面质量高，模具体也不易磨损。
