Description

机用丝锥
技术领域
本实用新型涉及一种机用丝锥。
背景技术
丝锥是机械加工常用的工具之一,是机械制造中用来加工零部件上需要制作螺纹的一种刃具,现有机用丝锥主要有直槽丝锥和螺旋丝锥两大类,直槽丝锥加工精度高,攻出的螺纹中径尺寸好,但切屑性能差,使用中耗力大,功效低,对难加工金属材料攻丝,易造成丝锥折断破裂;螺旋槽丝锥切削性能好,排屑流畅,但加工螺纹时定心精度低,从而使螺纹中径尺寸超差,以至于报废产品,且由于攻丝时定心度差,容易造成丝锥断裂;目前丝锥的材质为高速钢,由于该合金的价格比较高,使得丝锥的成本居高不下,提高了生产成本。
实用新型内容
本实用新型要解决的技术问题是:克服现有技术中之不足,提供一种不易折断、定心精度高以及成本低廉的机用丝锥
本实用新型解决其技术问题所采用的技术方案是:一种机用丝锥,具有攻丝头和圆柱形刀柄,所述的攻丝头和刀柄一体成型,攻丝头的侧壁上设置有2对均匀排列的高速工具钢攻丝刃,相邻两条攻丝刃之间这有排屑槽。
进一步的,所述的攻丝刃前角角度小于后角。
进一步的,所述的攻丝头长度是刀柄直径的1.8~2.2倍。
本实用新型的有益效果是:本实用新型具有良好的定心精度、切屑性能好,工作效率高,使用寿命长,成本低廉,克服了直槽丝锥和螺旋丝锥的缺点。
附图说明
下面结合附图和实施方式对本实用新型进一步说明。
图1是本实用新型的结构示意图。
图中1.攻丝头,2.刀柄,3.攻丝刃,4.排屑槽。
具体实施方式
现在结合附图对本实用新型作进一步的说明。这些附图均为简化的示意图仅以示意方式说明本实用新型的基本结构,因此其仅显示与本实用新型有关的构成。
如图1所示的一种机用丝锥,具有攻丝头1和圆柱形刀柄2,攻丝头1和刀柄2一体成型,攻丝头1的侧壁上设置有2对均匀排列的高速工具钢攻丝刃3,相邻两条攻丝刃3之间这有排屑槽4,攻丝刃3前角角度小于后角,攻丝头1长度是刀柄2直径的1.8~2.2倍。
上述实施方式只为说明本实用新型的技术构思及特点,其目的在于让熟悉此项技术的人士能够了解本实用新型的内容并加以实施,并不能以此限制本实用新型的保护范围,凡根据本实用新型精神实质所作的等效变化或修饰,都应涵盖在本实用新型的保护范围内。
