Abstract

本实用新型公开了一种旋转冲击式锚杆钻机用的钻头,主要解决现有钻机不耐冲击的缺陷。其结构是,它包括钻头体和合金刀,钻头体切削面下部有凹槽,合金刀镶嵌在凹槽里并铜焊在一起,所述的凹槽布置形式为垂直式或前倾式。本实用新型的优点是,由于合金刀既铜焊又镶嵌在钻头体上,所以耐冲击,合金刀不会脱落。

Description

旋转冲击式锚杆钻机用的钻头
技术领域
本实用新型涉及锚杆钻机钎具,尤其涉及钻头。
背景技术
目前市场上出现了旋转冲击式锚杆钻机,但用的钎具尤其是钻头仍采用旋转式锚杆钻机的钻头。这种钻头的合金刀直接垂直铜焊在钻头体切削面上,只符合旋转切削原理,虽然耐旋转,但不耐冲击,用于旋转冲击式锚杆钻机钻孔时合金刀很容易脱落。
发明内容
本实用新型的目的是解决钻头上的合金刀耐冲击问题,设计一种旋转冲击式锚杆钻机用的钻头。
为达到上述目的,本实用新型包括钻头体和合金刀,其特征在于,钻头体切削面下部有凹槽,合金刀镶嵌在凹槽里并铜焊在一起。
凹槽的布置形式有两种:一是垂直式,一种是前倾式。
本实用新型的优点是,由于合金刀即铜焊又镶嵌在钻头体上,所以耐冲击,合金刀不会脱落。
附图说明
图1是本实用新型合金刀垂直式布置的主视图;
图2是图1的侧视图;
图3是本实用新型合金刀前倾式布置的主视图,图中未示出合金刀。
图中:1-钻头体,2-合金刀;3-凹槽。
具体实施方式
下面结合
如图1、图2和图3所示,它包括钻头体1和合金刀2,钻头体1切削面下部有凹槽3,合金刀2镶嵌在凹槽3里并铜焊在一起。凹槽3的布置形式如图1的垂直式或图3的前倾式。
