Abstract

The invention discloses a laser welding diamond circular saw blade capable of continuous dry cutting, which relates to Diamond dry cutting saw blades. The present invention includes a carcass and a diamond saw head, the carcass includes the following components in weight percentage: Fe30%-40%, Co-containing alloy powder 25%-35%, Cu20%-30%, Ni8%-12% , Sn2%‑5%, the balance of Cr. The present invention is to manufacture a diamond circular saw blade capable of continuous dry cutting by improving the formula of the saw blade head and using pre-alloyed powder instead of cobalt powder combined with corrugated teeth, and adopting laser welding. It solves the problems of high-frequency welding saw blades that are prone to cutting heads and low safety performance. The design of the matrix components of the saw blade and the reasonable combination of diamonds. In addition, the use of laser welding can effectively ensure the strength of the saw blade and avoid roughness. Use to cause personal injury.

Description

technical field [0001] The present invention relates to The diamond dry cutting saw blade also relates to a manufacturing method of the diamond dry cutting saw blade. Background technique [0002] At present, domestic diamond circular saw blades mainly include pressureless sintered saw blades, hot-pressed sintered saw blades, high-frequency welded saw blades, and laser welded saw blades. At present, these saw blades have problems such as dry cutting, burning head, not sharp, low cutting efficiency, half cutting, falling head, and cracked substrate. Now many families in foreign countries use hand-held saws for sawing, and This hand-held saw is generally inconvenient to add water, and the saw blade product is required to be able to cut smoothly without adding water. [0003] The existing technical solution is to use saw blade head thinning, patterned water grooves on the blade teeth or high cobalt formula to improve the sharpness of the saw blade to achieve dry cutting. Th...
