AI Technical Summary

Technical Problem

Existing diamond saw blades suffer from damage to the saw teeth due to stress concentration and release during the cutting process.

Method used

It adopts a shallow inlet structure design, combined with the design of the first and second internal heat dissipation slots, and utilizes the attachment of diamond particles and the elastic fixation of rubber pads to enhance heat dissipation and stress gradation release. Furthermore, the substrate surface is sprayed with an anti-corrosion and friction coating to prevent loosening and extend service life.

Benefits of technology

It effectively reduces saw tooth chipping, improves cutting accuracy and quality, reduces noise, and extends saw blade life.

Abstract

本实用新型公开了一种浅水口阶段应力释放金刚石锯片，包括钢材质的锯片基体和锯片基体侧面的切割刀头，所述切割刀头外表面利用热压烧结附着金刚石颗粒，相邻切割刀头之间设置为排屑槽；所述锯片基体内部开设第一散热槽和第二散热槽，且所述第一散热槽和第二散热槽的位置相互对应，所述第一散热槽设置为条形结构，且所述第二散热槽设置为钥匙孔状结构。该浅水口阶段应力释放金刚石锯片，缩减排屑槽(即水口结构)的深度，使得锯片整体形成浅水口结构，浅水口可以提高刀头的强度(开槽深度小，刀头与基体可以更好的形成整体)，同时在锯片基体内部开设第一散热槽和第二散热槽，增强散热效果的同时利用开槽结构实现阶梯应力释放。
