Abstract

本实用新型是一种螺纹挤压丝锥，特别是一种圆顶圆底螺纹挤压丝锥，包括丝锥主体，丝锥主体的前端为攻丝段，丝段上设有攻丝螺纹，其特征在于：所述攻丝螺纹的断面成波浪形，波浪形的波峰和波谷均为圆弧形，波峰的半径为R1，波谷的半径为R2。由于丝锥螺纹的端面是圆顶圆底的螺纹，所以消除了原结构中的应力集中点，使加工时的应力得到分散，使承受的扭矩得到分解，解决了丝锥易粘料易断裂的难题，提高了丝锥的使用寿命，提升了工作效率。

Description

圆顶圆底螺纹挤压丝锥
技术领域
本实用新型是一种螺纹挤压丝锥，特别是一种圆顶圆底螺纹挤压丝锥。
背景技术
现有螺纹挤压丝锥，其攻丝部分为平顶平底螺纹，该螺纹的断面呈梯形状（见图3），梯形的顶部和底部分别存在两个尖点6，这些尖点构成了应力集中点，由于应力集中点的存在，导致丝锥易粘料易断裂，缩短了丝锥的使用寿命。
发明内容
本实用新型的目的是为了克服现有平顶平底螺纹挤压丝锥易粘料易断裂的缺陷，发明一种螺纹断面为圆顶圆底的螺纹挤压丝锥。
本实用新型的目的是按如下的方式来实现的：所述圆顶圆底螺纹挤压丝锥，包括丝锥主体，丝锥主体的前端为攻丝段，攻丝段上设有攻丝螺纹，其特征在于：所述攻丝螺纹的断面成波浪形，波浪形的波峰和波谷均为圆弧形，波峰的半径为R1，波谷的半径为R2。
本实用新型的积极效果如下：由于丝锥螺纹的端面是圆顶圆底的螺纹，所以消除了原结构中的应力集中点，使加工时的应力得到分散，使承受的扭矩得到分解，解决了丝锥易粘料易断裂的难题，提高了丝锥的使用寿命，提升了工作效率。

图3是现有丝锥的攻丝螺纹断面结构图
图中：1丝锥主体          2攻丝段           3攻丝螺纹
4波峰              5波谷             6尖点
具体实施方式
如图1图2所示，所述圆顶圆底螺纹挤压丝锥，包括丝锥主体1，丝锥主体1的前端为攻丝段2，丝段2上设有攻丝螺纹3，其特征在于：所述攻丝螺纹3的断面成波浪形，波浪形的波峰4和波谷5均为圆弧形，波峰4的半径为R1，波谷5的半径为R2。
由于丝锥螺纹的端面是圆顶圆底的螺纹，所以消除了原结构中的应力集中点，使加工时的应力得到分散，使承受的扭矩得到分解，解决了丝锥易粘料易断裂的难题，提高了丝锥的使用寿命，提升了工作效率。
