Abstract

本实用新型公开了一种用于加工钢、铁和铝合金材料的合金钻头。其具有刀柄、刀颈与刀体,刀体端部具有切削主刃,刀体周面上设置有排屑槽与螺旋型切削副刃,螺旋型切削副刃与水平方向的夹角为β,β为20°-35°,切削副刃的宽度为刀体直径的0.5倍-0.55倍。

Description

合金钻头
技术领域
本实用新型公开了一种用于加工钢、铁和铝合金材料的合金钻头。
背景技术
合金钻头用来加工普通钢、不锈钢、铁和铝合金材料的时候由于粘屑严重,钻头容屑槽堵塞,钻头容易断裂或损坏。
发明目的
本实用新型针对上述技术中钻头容易损坏的缺点,提供了一种排削好,不容易损坏的合金钻头。
实现本实用新型的技术方案如下:
合金钻头,其具有刀柄、刀颈与刀体,刀体端部具有切削主刃,刀体周面上设置有排屑槽与螺旋型切削副刃,螺旋型切削副刃与水平方向的夹角为β,β为20°-35°,切削副刃的宽度为刀体直径的0.5倍-0.55倍。
所述的主切削刃所在圆的直径为刀体直径的0.88倍-0.92倍。
采用了上述方案,合金钻头,其切削副刃与水平方向夹角比普通的钻头夹角大,切削副刃的宽度小,所以排屑槽宽,在其工作的时候排屑顺畅,钻头不容易损坏,本实用新型的优点是使合金钻头的使用寿命沿长,降低了生产成本,提高了生产效率。
附图说明
图1为本实用新型的结构示意图;
图中,1、刀柄,2、刀颈,3、刀体,4、排屑槽,5、切削副刃,6、切削主刃。
具体实施方式
如图1所示,合金钻头,其具有刀柄1、刀颈2与刀体3,刀体3端部具有切削主刃6,刀体3周面上设置有排屑槽4与螺旋型切削副刃5,螺旋型切削副刃5与水平方向的夹角为β,β为20°,切削副刃的宽度为刀体直径的0.5倍倍,主切削刃6所在圆的直径为刀体3直径的0.88倍。
