Description

Technical Field

[0001] This utility model belongs to the technical field of metal cutting and processing tools, specifically, it relates to a diamond rock slab 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, integrally formed by hot pressing and sintering with the matrix. The cutting of stone and other materials is achieved by utilizing the holding force of the matrix alloy on the diamond particles. Existing saw blades have a simple matrix and cutting head shape and structure, which does not improve cutting performance. To improve the cutting performance of diamond saw blades, a diamond slab cutting saw blade is provided. Summary of the Invention

[0003] In view of this, the technical problem to be solved by this utility model is to provide a diamond slab 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 diamond slab cutting saw blade, comprising: a base; a cutting part is provided on the edge of the base, and the front and back sides of the cutting part are respectively provided with convex teeth arranged in a ring array, the convex teeth are rhomboid in shape, and a groove is provided in the middle of the convex teeth, the groove is rhomboid in shape, and adjacent convex teeth are intersecting; multiple sets of heat dissipation holes are arranged in a ring array at the edge of the base, and each set of heat dissipation holes has at least two heat dissipation holes.

[0005] Furthermore, the thickness of the substrate is greater than the thickness of the cut portion.

[0006] Furthermore, the corners of the aforementioned protruding teeth facing the outer edge of the cutting part are pointed, while the corners facing the inner edge of the cutting part are rounded.

[0007] Furthermore, the aforementioned heat dissipation holes are quadrilaterals, with one pair of opposite edges having an arc-shaped profile and the other pair of opposite edges having a symmetrical, non-parallel shape.

[0008] Furthermore, the mounting holes of the aforementioned substrate have protruding reinforcing portions extending from both the front and back sides, and the reinforcing portions are in the shape of discs.

[0009] Compared with the prior art, this application can achieve the following technical effects:

[0010] The cutting part and the protruding teeth on its front and back sides of this utility model are integrally formed by hot pressing and sintering with a mold. The edges and surfaces of the protruding teeth can improve the biting force and cutting efficiency. The reinforcing part on the base can improve the stability of the base rotation. The multiple sets of heat dissipation holes on the base can accelerate the heat dissipation efficiency, thereby further improving the cutting performance of the saw blade.

[0011] 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
