Description

一种拉伸模具
技术领域
本实用新型涉及一种模具,尤其涉及一种铜管加工过程中用的拉伸模具。
背景技术
现有铜管加工过程中所用的拉伸模具,包括外模和内模,所述内模为方形,这种拉伸模具内模被外模卡死,没有松动空间,在铜管拉伸过程中容易造成铜管产品直径不均衡,钢性不稳定等现象,影响产品的质量。
实用新型内容
本实用新型的目的就是针对上述情况提供一种铜管加工过程中用的拉伸模具,该模具加工出的铜管直径均衡,钢性稳定。本实用新型的目的可通过以下方案来实现:一种拉伸模具,包括外模和内模,其特征是所述内模为半球形,所述外模中部设有与半球形内模相配套使用的凹坑,内模中部设有一个喇叭形进料通道,该进料通道与外模中部的出料通道相连通。本实用新型具有结构简单,使用效果好等特点,加工出来的铜管直径均衡,钢性稳定,大大提高了产品的质量。
附图说明
图1,本实用新型结构示意图。
具体实施方式
对照图1可知,一种拉伸模具,包括外模1和内模2,其特征是所述内模为半球形,所述外模中部设有与半球形内模相配套使用的凹坑,内模中部设有一个喇叭形进料通道3,该进料通道3与外模中部的出料通道4相连通。
