Abstract

本实用新型属于机械零件的模压工具，它是一种下台阶螺母冲模的冲头，其特征是在冲杆的端面正中开有一个凹形圆槽，凹形圆槽的直径和深度与所设计螺母下台阶的直径和高度一致。用本实用新型结构的冲模冲头，能直接冲压出下台阶螺母毛坏，生产效率高，能保证螺母台阶尺寸与螺纹中心尺寸的同轴度、质量好。

Description

下台阶螺母冲模的冲头
一、技术领域
本实用新型属于模压工具，具体涉及机械零件的冲压模制工具。
二、背景技术
现有的螺母冲模只能冲压出普通平口螺母毛坯，对于带下台阶的异型螺母，其下台阶现有技术是用平口螺母毛坯，再上车床将一端进行车削而成，这种加工方法不仅生产效率低，而且加工质量差，螺母台阶尺寸与螺纹中心尺寸的同轴度难以保证，另外加工也极不方便，还浪费材料。
三、发明内容
本实用新型的目的就在于针对上述现有技术的缺陷，设计一种专门用来冲压模制下台阶螺母毛坯的冲模冲头。
本实用新型所设计的技术方案如下。
一种下台阶螺母冲模的冲头，包括有夹持头和六角冲杆，其特征是在六角冲杆的端面正中开有一个凹形圆槽，凹形圆槽的直径和深度与所设计螺母下台阶的直径和高度一致。用本实用新型结构的冲模冲头，能直接冲压出下台阶螺母毛坯，生产率高，在螺母的后加工中，勉去了上车床车削下台阶的工序，能保证螺母台阶尺寸与螺纹中心尺寸的同轴度，质量好，节约材料。
四、附图说明
图1是本实用新型冲头的结构示意图；
图2是本实用新型冲头的工作状况参考图。
在图中：1-夹持头  2-六角冲杆  3-冲头  4-成形螺坯  5-六角模  6-顶模
五、具体实施方式
下面结合附图，对本实用新型冲头的结构做更进一步的说明。
一种下台阶螺母冲模的冲头，包括有夹持头1和六角冲杆2，其特征是在六角冲杆2的端面正中开有一个凹形圆槽，凹形圆槽的直径和深度与所设计螺母下台阶的直径和高度一致。
