Abstract

一种下排屑的螺旋槽丝锥。包括锥柄、方头、切削齿的结构,右旋螺纹用丝锥的容屑槽的螺旋向左或左旋螺纹用丝锥的容屑槽螺旋向右。攻丝时,出屑顺畅,降低了切削负荷,丝攻不易折断,攻丝的效率和精度相对较高,同时,延长丝锥的使用寿命40%以上。

Description

一种下排屑的螺旋槽丝锥
一、技术领域:
本实用新型一种下排屑的螺旋槽丝锥,涉及的是螺纹工具设计制造技术领域,应用于螺纹加工。
二、背景技术:
目前,加工通孔螺纹时,一般采用容屑槽为直槽的丝锥,丝锥在攻丝过程中,通过挤压的方式将切割向下排挤,排屑较为困难,切屑被挤压在容屑槽内,切削负荷增大,容易折断的丝锥,很难取出,往往造成工件报废。
三、发明内容:
本实用新型的目的在于克服上述的缺陷,对现有技术加以改进,改直线的容屑槽为螺旋形的结构,达到切屑顺螺旋角排出的一种下排屑的螺旋槽丝锥。其技术是这样实现的:包括锥柄、方头、切削齿的结构,其特征在于:右旋螺纹用丝锥的容屑槽的螺旋向左或左旋螺纹用丝锥的容屑槽螺旋向右。实施该技术后的明显优点在于:首先在攻丝时,克服了上述缺陷,出屑顺畅,降低了切削负荷,丝锥不易折断,攻丝的效率提高,精度保证,同时,延长丝锥的使用寿命40%以上。
三、附图说明:
图1为本实用新型的结构示意图;
其中,1-方头、2-锥柄、3-丝锥、3-1-切削齿、4-螺旋容屑槽;
五、具体实施方法:
以下结合附图,对本实用新型作进一步描述:
见附图1,锥柄(2)的端头设有方头(1)三条左向螺旋容屑槽(4)贯通丝锥(3)的切削齿(3-1)的整体结构。
见附图1,根据尺寸设计要求,依据丝锥的一般加工工艺,经锻料、车削粗加工外形,铣方头(1),粗铣三条左向螺旋容屑槽(4),粗车丝锥(3)的切削齿(3-1)之后,丝锥被加热至1250°±10进行热处理,硬度达HRC63-66,进行粗、精磨切削齿(3-1)外径,粗、精磨左向容屑槽(4)和锥柄(2),精磨丝锥(3)的切削齿(3-1)和丝锥(3)的切削锥,经检验、包装入库。
通孔攻丝时,丝锥向下旋转,切屑沿着容屑槽(4)自然下落,在不增加切削负荷的情况下,顺利完面攻丝工作。
