Description

一种干切锯片
技术领域
本实用新型属于切割工具技术领域,特别涉及一种干切锯片。
背景技术
小锯片在干式切割过程中与被切割材料摩擦产生大量的热量,易使钢基体变形,从而导致锯片的切割效率和使用寿命度大幅度降低。为此,人们开发出一种涡轮加强锯片,在钢基体的制造过程中,把原来平板钢基体冲压成沿中心向外辐射的波纹形状,以增加钢基体的强度,但同时也增加了钢基体的厚度,使得锯片刀头厚度也相应增加,在切割时增加了切缝阻力,降低了锯片的切割效率。
实用新型内容
本实用新型目的在于提供一种使用寿命长的干切锯片,其进一步的目的在于提供一种使用寿命长、切割效率高的干切锯片。
为达上述目的,本实用新型采用如下技术方案:一种干切锯片,包括钢基体和均设于钢基体外缘的刀头,刀头背部设有保护齿,保护齿嵌接于钢基体内。
保护齿厚度与刀头厚度相同但大于钢基体厚度。
相邻两个刀头嵌入基体内的保护齿长度不同,间隔两个刀头嵌入基体内的保护齿长度相同。
本实用新型可使用平板钢基体,每个刀头都有一部分保护齿嵌入钢基体内部,刀头和钢基体的结合强度较高,提高了锯片使用的安全性-不掉刀头;由于嵌入钢基体内部的保护齿厚度大于钢基体厚度,在切割过程中可以起到保护钢基体的作用,保证钢基体和刀头结合处不会因被切割材料的冲击变薄而使刀头提前脱落,锯片使用寿命长;长保护齿在锯片切割时保证钢基体不接触被切割工件,从而减少了因磨擦生热而使钢基体变形的可能性;本实用新型中的结构设计保证钢基体不受摩擦,在切割过程中不会夹锯,同时深入到钢基体内部的八个保护齿起到了良好的排屑作用,大大提高了切割效率,非常适合于切割研磨性较强的材料。本实用新型可以完全替代传统的涡轮加强锯片。
附图说明
图1为本实用新型结构示意图;
图2为图1的A-A剖视图。
具体实施方式
一种干切锯片,包括钢基体1和均设于钢基体1外缘的八个刀头,刀头背部设有保护齿,保护齿嵌接于钢基体1内。保护齿厚度与刀刀头厚度相同但大于钢基体厚度。相邻两个刀头2、3嵌入基体1内的保护齿2-1、3-1长度不同,间隔两个刀头2、4嵌入基体1内的保护齿2-1、4-1长度相同。
