Abstract

本实用新型属玛瑙加工刀具,特别涉及一种用于玛瑙加工的双刃金刚石钻头,由钻杆(1)、出屑槽(3)和金刚石工作层(4)组成,钻头体(3)制成并列断面为圆形柱体,由于将原钻头为方形柱体,改为圆形柱体,去掉了棱角,金刚石工作层磨损均匀,延长了钻头寿命一倍以上。

Description

双刃金刚石钻头
技术领域
本实用新型属玛瑙加工刀具,特别涉及一种用于玛瑙加工的双刃金刚石钻头。
技术背景
目前,国家知识产权局授权一种“分刃金刚石钻头”,专利公开号CN2495400y,该钻头解决了排屑和冷却问题,但是钻头断面为方形,棱角磨损快,使用寿命低。
发明内容
本实用新型的目的在于克服上述技术不足,提供一种耐磨损、寿命长的双刃金刚石钻头。
本实用新型解决技术问题采用的技术方案是:一种由钻杆、出屑槽和金刚石工作层组成的双刃金刚石钻头,其特点是固定在钻杆上的钻头体制成并列两个断面圆形柱体。
本实用新型的有益效果是:由于将原钻头为方形柱体,改为圆形柱体,去掉了棱角,金刚石工作层磨损均匀,延长了钻头寿命一倍以上。
附图说明
以下结合附图以实施例具体说明。
图1示双刃金刚石钻头主视图。
图2示图1的俯视图。
图3示图1的左视图。
图中,1-钻杆;2-出屑槽;3-钻头体;4-金刚石工作层;
具体实施方式
参照附图,一种用于玛瑙加工钻孔的双刃金刚石钻头,由钻杆1、出屑槽2和金刚石工作层组成,它的特点是固定在钻杆1上的钻头体3制成并列两个断面为圆形柱体,钻孔时磨损均匀,延长了钻头的使用寿命。钻头体3两侧对称地设有出屑槽2,钻孔时,将切削、研磨下来的玛瑙石粉末从出屑槽2中排出孔外,减小磨擦,有利于钻头体3散热。钻头体3圆周上采用电铸沉积的方法,将超硬金刚石固定在钻头体3上,制成了金刚石工作层4,解决了加工玛瑙硬度摩氏高,钻具磨损快的问题。
双刃金刚石钻头,适用于玛瑙、玉石等坚硬物品的加工、研磨,耐磨性好,使用寿命长。
