Description

高速钢铲钻刀片
技术领域
本实用新型涉及一种五金加工工具，特别是一种适合加工硬质材料的高速钢铲钻刀片。
背景技术
现有市场中麻花钻规格都较小，大规格采用整体式成本会很高且不易加工；钻尖的刃磨技术要求高，往往无法达到刃磨的技术要求，使得加工效率与质量受到影响。
发明内容
本实用新型所要解决的技术问题是克服现有技术中所存在的上述不足，而提供一种成本低，无需刃磨端齿的高速钢铲钻刀片。
本实用新型解决上述技术问题所采用的技术方案是：该高速钢铲钻刀片，包括固定部位与切削部位，特征在于固定部位包括定位槽、螺钉孔，切削部位包括修磨横刃、排屑分割槽、断屑槽、刃带、外倒角、主切削刃，高速钢铲钻刀片下端中间为定位槽，高速钢铲钻刀片中间有两个螺钉孔，螺钉孔轴线与刀片侧面垂直，主切削刃上设有排屑分割槽，高速钢铲钻刀片刃口带有修磨横刃，高速钢铲钻刀片外圆设有刃带，高速钢铲钻刀片前角面设有断屑槽，高速钢铲钻刀片钻尖处设有外倒角。
本实用新型主切削刃顶角角度为90°～150°。
本实用新型具有结构简洁，成本低，无需刃磨端齿等特点。
附图说明
图1为本实用新型实施例的主视图。
图2为图1的俯视图。
具体实施方式
参见图1、图2，本实施例高速钢铲钻刀片包括固定部位与切削部位，固定部位包括定位槽1、螺钉孔2，切削部位包括修磨横刃3、排屑分割槽4、断屑槽5、刃带6、外倒角7、主切削刃8。
高速钢铲钻刀片下端中间为定位槽1，定位槽1形状可以是长方形或其它形状，可以很好的定位在刀体上；
高速钢铲钻刀片中间有两个螺钉孔2，其轴线与刀片侧面垂直，可以更好的固定；
高速钢铲钻刀片的主切削刃8顶角角度为90°～150°，主切削刃8上设有排屑分割槽4，可以有效的进行分屑；
高速钢铲钻刀片刃口带有修磨横刃3，可减小轴向力及扭距，修磨横刃3可以是X形或H形等；
高速钢铲钻刀片外圆有刃带6；
高速钢铲钻刀片前角面带有断屑槽5，可以更有效的进行断屑；
高速钢铲钻刀片钻尖处外倒角7，提高钻尖强度，减少崩刃。
凡是本实用新型实施例技术方案和技术特征的简单变形或组合，均应认为落入本实用新型的保护范围。
