Abstract

本实用新型加工清根螺纹的硬质合金刀片,切削部包括左、右切削刃,左、右切削刃间有一凸出的矩形切削部。在加工螺纹的同时进行清根,使用方便,生产效率高,同时能有效地保证加工质量。

Description

加工清根螺纹的硬质合金刀片
技术领域
本实用新型涉及一种硬质合金刀片,特别是加工螺纹的硬质合金刀片。 
背景技术
现有的加工螺纹的硬质合金刀片,如图1、2所示,切削部的左、右刃通过圆弧连接,切削出的螺纹无法清根,在一些特殊领域,如螺纹量规的加工领域,要求加工出的螺纹清根,普通的刀片无法达到使用要求,用户只能用普通螺纹刀片先加工出螺纹,然后再用自制的清根刀对加工出的螺纹清根,不但效率低下,质量也无法保证。 
实用新型内容
本实用新型旨在提供加工清根螺纹的硬质合金刀片,加工螺纹的同时进行清根,加工方便,效率高,可有效地保证加工质量。 
本实用新型的技术方案为:加工清根螺纹的硬质合金刀片,切削部包括左、右切削刃,左、右切削刃间有一凸出的矩形切削部。 
进一步的,所述硬质合金刀片呈三角形,切削部有三个。 
本实用新型在加工普通螺纹的同时进行清根,使用方便,生产效率高,同时能有效地保证加工质量。 
附图说明
图1所示为现有加工螺纹的硬质合金刀片结构示意图。 
图2所示为图1所示A部放大图。 
图3所示为本实用新型结构示意图。 
图4为图3所示的B部放大图。 
图中:1-切削部,2-左切削刃,3-右切削刃,4-矩形切削部。 
具体实施方式
如图3所示,本实用新型加工清根螺纹的硬质合金刀片,切削部1包括左、右切削刃2、3,左、右切削刃2、3间有一凸出的矩形切削部4,矩形切削部4的结构如图4所示,凸出的矩形切削部4可在加工出螺纹的同时在根部切出凹槽。 
进一步的,刀片呈三角形,切削部1有三个,可提高刀片的使用寿命。 
当然,本实用新型还可有其它多种实施例,在不背离本实用新型精神及其实质的情况下,熟悉本领域的技术人员可根据本实用新型作出各种相应的改变和变形,但这些相应的改变和变形都应属于本实用新型所附的权利要求的保护范围。 

Claims (2)

1.加工清根螺纹的硬质合金刀片,其特征在于:切削部包括左、右切削刃,左、右切削刃间有一凸出的矩形切削部。
2.根据权利要求1所述的加工清根螺纹的硬质合金刀片,其特征在于:所述硬质合金刀片呈三角形,切削部有三个。
