Description

Technical Field

[0001] This utility model belongs to the technical field of metal cutting and processing tools, specifically, it relates to a U-shaped diamond cutting saw blade. Background Technology

[0002] Diamond saw blades are sawing tools widely used for cutting hard and brittle materials such as concrete, refractory materials, stone, and ceramics. A diamond saw blade mainly consists of two parts: a matrix and a cutting head. The cutting head is generally composed of a matrix alloy and a certain proportion of diamond particles. The cutting is achieved by utilizing the holding force of the matrix alloy on the diamond particles. Currently, the cutting part of diamond saw blades produced by each manufacturer is made of matrix alloy and diamond particles, and their cutting performance is roughly the same, lacking technological breakthroughs. To improve the cutting performance of diamond saw blades, a U-shaped tooth diamond cutting saw blade is proposed. Summary of the Invention

[0003] In view of this, the technical problem to be solved by this utility model is to provide a U-shaped diamond cutting saw blade, which solves the problem of weak cutting performance of existing cutting saw blades.

[0004] To solve the above-mentioned technical problems, this utility model discloses a U-shaped diamond cutting saw blade, comprising: a base; a reinforcing part is provided at the center of the base, the reinforcing part protrudes to both sides of the base, a mounting hole is provided at the center of the reinforcing part, a plurality of heat dissipation holes are provided at intervals around the periphery of the reinforcing part, a cutting part is provided at the edge of the base, a plurality of heat dissipation holes are provided at intervals between the cutting part and the reinforcing part, and a plurality of protruding U-shaped teeth are provided on both sides of the cutting part.

[0005] Furthermore, one of the aforementioned heat dissipation holes is semi-circular.

[0006] Furthermore, the aforementioned cut portion is annular, and its thickness is less than that of the substrate.

[0007] Furthermore, the aforementioned U-shaped teeth protrude from the surface of the substrate, and the centerline of the opening of the U-shaped teeth forms an angle of 5 to 20° with the centerline of the substrate.

[0008] Furthermore, the surface of the U-shaped tooth is provided with grooves with a width of micrometers, and multiple grooves are distributed at intervals on the surface of the U-shaped tooth.

[0009] Furthermore, the angle between the centerline of the aforementioned groove and the centerline of the substrate is greater than the angle between the centerline of the U-shaped tooth opening and the centerline of the substrate.

[0010] Compared with the prior art, this application can achieve the following technical effects:

[0011] This invention features a cutting section at the edge of the substrate, with U-shaped teeth on the cutting section. The cutting section and the U-shaped teeth are made of matrix alloy and diamond particles. The opening of the U-shaped teeth can accelerate chip removal efficiency, and the micron-level grooves on the surface of the U-shaped teeth can improve cutting performance, thereby improving the overall cutting performance of the substrate.

[0012] Of course, any product implementing this application does not necessarily need to achieve all of the technical effects described above at the same time. Attached Figure Description
