Abstract

有压光弧的直线形金刚石拉丝模具，在现有的直线形金刚石拉丝模具的内孔的定径区、倒锥之间增加一个压光弧。这种有压光弧的直线形金刚石拉丝模具可以有效防止剐丝，提高金属丝的表面质量。

Description

有压光弧的直线形金刚石拉丝模具
(一)技术领域：
本实用新型属于金属线材拉拔制造领域，具体地说是一种有压光弧的直线形金刚石拉丝模具。
(二)背景技术：
拉丝模具是拉拔各种金属线材的关键工具。为了提高生产效率，现在越来越多的厂家使用高速拉丝机拉丝。高速拉丝需要用直线形金刚石拉丝模具，现有的直线形金刚石拉丝模具的内孔分为：入口、压缩工作部、定径区、倒锥、出口五个部分，其中，定径区是圆柱形，其它部分是圆锥形，各部分之间有明显的交界线。在拉丝过程中，金属丝要受到很大的拉拔力，产生变形，金属丝表面的氧化层会剥落，加之拉丝过程中加入的润滑粉、润滑液中的微小颗粒的作用，金属丝会在定径区的出口处，即：在定径区与倒锥的交界线处产生剐丝，金属丝的表面被划伤，表面质量下降。这就需要改进拉丝模具的孔型，克服这种剐丝现象。
通过对目前拉丝模具生产厂家的考察，没有发现享有、生产、使用有压光弧的直线形金刚石拉丝模具。
通过对有关技术刊物、书籍的查阅，没有发现关于有压光弧的直线形金刚石拉丝模具技术的报道、记载。
通过对现有的中国专利检索查阅，没有发现关于有压光弧的直线形金刚石拉丝模具的专利。
(三)发明内容：
本实用新型的目的是提供一种有压光弧的直线形金刚石拉丝模具。
本实用新型的技术方案是：在直线形金刚石拉丝模具的内孔的定径区3、倒锥5之间增加一个压光弧4。
与现有技术比较，有益的效果是：有压光弧的直线形金刚石拉丝模具可以有效防止剐丝，提高金属丝的表面质量。
(四)附图说明：
附图是有压光弧的直线形金刚石拉丝模具的立体中剖示意图。
(五)具体实施方式：
如附图所示，附图中标明了：入口1、压缩工作部2、定径区3、压光弧4、倒锥5、出口6。
从附图中可见：在直线形金刚石拉丝模具的内孔的定径区3、倒锥5之间增加一个压光弧4。
现有技术比较，有益的效果是：有压光弧4的直线形金刚石拉丝模具可以有效防止剐丝，提高丝的表面质量。
