Description

铲钻刀片
技术领域
本实用新型涉及一种五金加工工具，特别是一种适用于加工软材料的硬质合金铲钻刀片。
背景技术
现有市场中硬质合金类的麻花钻规格都较小，大规格采用整体式成本会很高且不易加工；且采用焊接式的硬质合金麻花钻加工复杂，使用寿命短。
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，而提供一种能够方便装载的铲钻刀片，并且能够提高钻头使用效率和使用寿命、提高加工精度。
本实用新型解决上述技术问题所采用的技术方案是：该铲钻刀片，包括固定部位与切削部位，特征在于固定部位包括V形定位面、螺钉孔，切削部位包括主切削刃、修磨横刃、外直刃、刃带和负切削刃，V形定位面与刀体配合，铲钻刀片中间设有一个螺钉孔，主切削刃为波形刃并采用W型修磨钻尖，主切削刃带有修磨横刃，铲钻刀片外圆设有刃带，铲钻刀片两侧带有负切削刃。
本实用新型螺钉孔的轴线与刀片侧面垂直线有5°～40°的夹角。
本实用新型结构简洁，方便装卸，提高钻头使用效率、使用寿命和加工精度。
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，本实施例硬质合金铲钻刀片包括固定部位与切削部位，固定部位包括V形定位面1、螺钉孔2，切削部位包括主切削刃3、修磨横刃4、外直刃5、刃带6和负切削刃7。
⑴、刀片装夹部位为适当角度的V形定位面1，其与刀体配合可以很好的定位在刀体上；
⑵、铲钻刀片中间有一个螺钉孔2，其轴线与刀片侧面垂直线有5°～40°的夹角；
⑶、铲钻刀片的主切削刃3采用W型修磨钻尖，可增加刀具使用寿命，减小轴向力及扭距并带有修磨横刃4；
⑷、铲钻刀片外圆有刃带6；
⑸、铲钻刀片两侧带有负切削刃7，增加刃口的强度；
⑹、主切削刃3采用波形刃，增加刀具的切削锋利性与切削刃强度；
⑺、前角加大，后角加大，切削锋利。
由于采用机夹方法，使得装夹简单，铲钻刀片可根据实际需要随时替换。
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。
