Diamond saw blade and preparation method

Abstract

The invention discloses a diamond saw blade and a preparation method. The diamond saw blade includes a disc matrix. A plurality of cutting units are evenly arranged along the outer circumference of the matrix. The center of the matrix is provided with an axle hole. The cutting units are in the same shape, and each cutting unit includes at least two diamond cutter heads. The cross section of each diamond cutter head is U-shaped, and each diamond cutter head is mounted at the edge of the matrix in a crossing mode. The outermost side of each diamond cutter head is distributed in a circle and theinnermost side of each diamond cutter head overlaps with the upper and lower surfaces of the matrix. Through structure improvement, the stiffness of the matrix and the service life of the saw blade are improved, further, the interface bonding between diamond particles and a metal blank body is improved, thus the utilization rate of the diamond particle in the diamond saw blade is increased, so thecutting efficiency and service life are increased, and finally the high-efficiency and low-cost diamond saw blade is obtained.

Description

technical field [0001] The invention relates to a diamond saw blade and a preparation method thereof. Background technique [0002] Diamond saw blade is a cutting tool, which is widely used in the processing of hard and brittle materials such as concrete, refractory materials, stone, ceramics, etc. Diamond saw blade is mainly composed of two parts: the base body and the cutter head. Among them, the matrix is ​​the main supporting part of the bonded cutter head, and the cutter head is the part that cuts during use. The reason why the cutter head can cut is because it contains diamond particles, and the diamond particles are made of metal matrix. Wrapped in the cutter head, it frictionally cuts the processed object in the cutter head, and the cutter head will be continuously consumed during use. [0003] The thickness of the existing diamond saw blade base and cutter head is equal. In order to improve the rigidity of the saw blade, several slightly protruding ribs will be set...

AI Technical Summary

Problems solved by technology

[0003] The thickness of the existing diamond saw blade base and cutter head is equal. In order to improve the rigidity of the saw blade, several slightly protruding ribs will be set on the surface of the base. This structure increases the difficulty of the base preparation process. In addition, the saw blade The performance not only depends on the performance of the selected diamond and the metal matrix itself, but also depends on the interface between the diamond and the metal matrix. Due to the poor wettability between the diamond particles and the metal binder, the metal matrix The ability of the body to hold diamonds is low, which will cause the diamond particles in the prepared saw blades to fall off before they are worn out, resulting in a reduction in cutting efficiency and an increase in use costs
