Abstract

本实用新型公开了一种驱动桥半壳压型模具,包括凸模和凹模,所述的凸模的冲头的端面上固定有锥销。本实用新型在压型时能对板料进行准确定位,使成型后的驱动桥半壳的中部圆弧距端面尺寸偏差控制在±1mm内。

Description

一种驱动桥半壳压型模具
(一)技术领域
本实用新型涉及一种模具,特别涉及一种驱动桥半壳压型的模具。
(二)背景技术
驱动桥半壳是板料在中频炉加热到900多度后,由压力机压入模具成型,按照加工要求成型后无须任何机械加工,只须整形即可使用,因此对成型后的半壳尺寸精度要求较高。压型时模具圆弧部顶端首先接触到板料,由于模具圆弧段距两端的直线段尺寸不等,造成在凸模压入时板料两端进入模具的速度不等,板料沿凸模圆弧产生左右错移,无法保证半壳圆弧部位距两端的±1mm尺寸精度要求。
(三)发明内容
本实用新型要解决的技术问题是:提供一种加工出的产品尺寸精度高的驱动桥半壳压型模具。
为了解决上述技术问题,本实用新型包括凸模和凹模,所述的凸模的冲头的端面上固定有锥销。
为了板材定位后不产生错移,所述的锥销有两个。
为了不影响驱动桥半壳的质量,所述的锥销直径小于或等于10mm,锥销处在凹模之外的高度为桥壳厚度的1/3。
本实用新型在压型时能对板料进行准确定位,使成型后的驱动桥半壳的中部圆弧距端面尺寸偏差控制在±1mm内。
(四)附图说明
图1是本实用新型的主视结构示意图;
图2是图1的的左视图;
图3是本实用新型的局部放大图;
图中:1、凸模,2、锥销,3、板料,4、凹模。
(五)具体实施方式
如图1、图2所示的一种驱动桥半壳压型模具,包括凸模1和凹模4,凸模1的冲头的端面为圆弧面,在该圆弧面上固定有两个间隔开的锥销2,锥销2直径小于或等于10mm,锥销2处在凹模4之外的高度为桥壳厚度的1/3。
压型时,将板料3平放在凹模4上的入口部,凹模4对板料3进行初始定位,由凸模1压入。压入时凸模1上的锥销2首先压入板料3,对板料3定位,继续压入时板料3无法左右错移,保证了压型后半壳的尺寸精度要求。

Claims (3)

1.一种驱动桥半壳压型模具,包括凸模(1)和凹模(4),其特征在于:所述的凸模(1)的冲头的端面上固定有锥销(2)。
2.根据权利要求1所述的一种驱动桥半壳压型模具,其特征在于:所述的锥销(2)有两个。
3.根据权利要求1或2所述的一种驱动桥半壳压型模具,其特征在于:所述的锥销(2)直径小于或等于10mm,锥销(2)处在凹模(4)之外的高度为桥壳厚度的1/3。
