Abstract
Description
Technical Field
[0001] This utility model relates to the field of diamond saw blade technology, specifically to a double-row diamond saw blade. Background Technology
[0002] In fields such as stone processing, concrete construction, and metal cutting, diamond saw blades have become indispensable cutting tools due to their high hardness and wear resistance. Currently, most diamond saw blades on the market adopt a single-row cutter head structure, meaning that only one row of diamond cutters is set along the circumference of the saw blade body. In actual use, this traditional structure, due to its unreasonable cutter head layout, fails to effectively distribute the stress generated during cutting, causing the saw blade body to directly bear a large cutting force and friction, thus leading to severe wear of the saw blade body.
[0003] Wear of the saw blade's matrix can lead to a series of serious consequences. Firstly, reduced matrix strength makes it prone to deformation or even breakage during cutting, significantly impacting the saw blade's safety and stability. Secondly, matrix wear disrupts the saw blade's overall dynamic balance, causing severe vibrations during cutting. This not only reduces cutting accuracy but also further accelerates blade wear, creating a vicious cycle and shortening the saw blade's lifespan. Furthermore, frequent replacements of saw blades that fail due to matrix wear significantly increase processing costs and downtime, reducing production efficiency.
[0004] Therefore, there is an urgent need for a diamond saw blade with an optimized structural design to effectively solve the problem of severe substrate wear in existing technologies. Utility Model Content
[0005] To address the aforementioned problems, this utility model discloses a double-row diamond saw blade.
[0006] To achieve the above objectives, this application discloses a double-row diamond saw blade, comprising: a saw blade base; and a plurality of diamond cutter head assemblies arranged circumferentially along the saw blade base; each diamond cutter head assembly includes:
[0007] First cutter head assembly;
[0008] Second cutter head assembly;
[0009] The first and second cutter head groups are arranged at intervals along the circumference of one side of the saw blade substrate, and the diamond cutter heads of the first and second cutter head groups extend toward the center of the saw blade substrate.
[0010] The first cutter head assembly is located outside the second cutter head assembly; the first cutter head assembly extends to the end of the second cutter head assembly on the other side of the saw blade base.
[0011] The first cutter head group is arranged in a staggered manner with each diamond cutter head of the second cutter head group on the other side of the saw blade base.
[0012] A U-shaped groove is provided between adjacent diamond tool tip groups.
[0013] The saw blade substrate has multiple heat dissipation holes.
[0014] In the saw blade of this application, the first and second cutter head groups are arranged circumferentially on one side of the saw blade substrate, forming a double-row cutting edge structure. Compared with the traditional single-row cutter head, this design allows the saw blade to distribute the force more evenly during cutting, effectively reducing the problem of local stress concentration at the cutter head. Secondly, the diamond cutter heads of both groups extend towards the center of the saw blade substrate. During the cutting process, the cutter head, as the main cutting component, directly contacts the material being cut, while the edge of the substrate is covered by the cutter head, avoiding direct friction and collision with the material, thereby significantly reducing the wear of the substrate and effectively maintaining the structural strength and rigidity of the substrate.

[0019] The present invention will be further illustrated below with reference to specific embodiments. It should be understood that the following specific embodiments are for illustrative purposes only and are not intended to limit the scope of the present invention. It should be noted that the terms "front," "rear," "left," "right," "up," and "down" used in the following description refer to the directions in the accompanying drawings, and the terms "inner" and "outer" refer to the directions toward or away from the geometric center of a specific component, respectively.
[0020] Example: Figure 1-4 As shown, a double-row diamond saw blade includes: a saw blade base 1; and a plurality of diamond cutter head groups 2 arranged circumferentially along the saw blade base 1; each diamond cutter head group 2 includes:
[0021] First cutter head group 21;
[0022] Second cutter head assembly 22;
[0023] The first cutter head group 21 and the second cutter head group 22 are arranged at intervals along the circumference on one side of the saw blade base 1, and the diamond cutter heads of the first cutter head group 21 and the second cutter head group 22 are both extended toward the center of the saw blade base 1.
[0024] In this embodiment, the saw blade base 1 can be made of high-strength metal (such as alloy steel) to provide a stable mounting platform for the diamond cutter head assembly. Multiple diamond cutter head assemblies 2 are evenly distributed along the circumference of the saw blade base. Each assembly includes a first cutter head assembly 21 and a second cutter head assembly 22, which are arranged at intervals on one side of the base, and the diamond cutting edges of all cutters extend towards the center of the base.
[0025] The first and second cutter head groups are alternately distributed in the circumferential direction, forming a "double-row cutting edge" structure. Compared with a single-row cutter head, the number of cutter heads participating in cutting per unit circumference increases, and the two sets of cutter heads can act on the cutting surface simultaneously, dispersing the single-point cutting stress. This allows the saw blade to withstand greater cutting resistance when cutting hard materials (such as stone and concrete), reducing the risk of cutter head breakage and achieving higher cutting strength and efficiency. The alternately arranged cutter head groups cut into the material during rotation, avoiding excessive wear of a single cutter head. At the same time, the synchronous cutting of the double-row cutting edges enhances the material crushing ability, making it particularly suitable for cutting thick plates or high-hardness materials.
[0026] The diamond cutting tip extends a considerable length towards the center of the substrate, forming a "wrap-around protection" around the substrate edges. During cutting, the cutting tip, as the front-end cutting component, directly contacts the material, while the substrate edges are covered by the cutting tip, avoiding direct friction or collision between the substrate and the material being cut, thus significantly reducing substrate wear.
[0027] In one embodiment, the first cutter head assembly 21 is located outside the second cutter head assembly 22; the first cutter head assembly 21 extends to the end of the second cutter head assembly 22 on the other side of the saw blade base 1. The first cutter head assembly 21 is located outside the second cutter head assembly 22, a positional relationship determined based on the saw blade base 1. From the radial direction of the saw blade, with the center of the saw blade base 1 as a reference, the first cutter head assembly 21 is farther from the center, while the second cutter head assembly 22 is relatively closer to the center. During the cutting process, different cutter head assemblies undertake different cutting tasks. The outer first cutter head assembly 21 may first contact the material being cut, playing a role in initial cutting and crushing, while the inner second cutter head assembly 22 can further trim and refine the cut area.
[0028] The first cutter head group 21 is offset from the diamond cutter heads of the second cutter head group 22 on the other side of the saw blade base 1. The diamond cutter heads of the first cutter head group 21 and the second cutter head group 22 are not one-to-one corresponding in the circumferential direction of the saw blade, but are staggered. This staggered arrangement allows for more even force distribution on the cutter heads during cutting, avoiding concentrated force on the same circumferential position, thereby reducing the wear rate of the cutter heads and extending their service life. Furthermore, the staggered cutter heads can perform more precise cutting of the material, improving the smoothness and finish of the cut surface. For example, after the first cutter head group 21 cuts the material once, the staggered cutter heads of the second cutter head group 22 can immediately perform a second cut on the same area, removing any remaining protrusions and making the cut surface smoother.
[0029] A U-shaped groove 3 is provided between adjacent diamond cutter head assemblies 2. The U-shaped groove provides a channel for the discharge of chips generated during cutting, preventing chips from accumulating between the cutter heads, which would increase cutting resistance or scratch the cutting surface. Cutting fluid or airflow can reach the cutter head area more efficiently through the U-shaped groove, enhancing the cooling effect and reducing wear of the cutter head caused by high temperature.
[0030] The saw blade base 1 has multiple heat dissipation holes 4. In a specific design, the multiple heat dissipation holes 4 are evenly distributed on the saw blade base 1, usually located inside the cutter head assembly or in the central area of the base. When the saw blade rotates at high speed, the air inside the heat dissipation holes is thrown out due to centrifugal force, forming an outward airflow (similar to the principle of a centrifugal pump), thereby achieving ventilation and heat dissipation.
[0031] The technical means disclosed in this utility model are not limited to those disclosed in the above embodiments, but also include technical solutions composed of any combination of the above technical features. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications are also considered within the scope of protection of this utility model.
