Description

Technical Field

[0001] This utility model belongs to the field of grinding wheel technology, specifically, it relates to a corrugated tooth grinding wheel. Background Technology

[0002] Diamond grinding wheels are made by welding diamond grinding teeth onto a metal substrate. The diamond grinding teeth are formed by cold pressing or hot pressing and sintering synthetic industrial diamonds and other metal powders, and then welding them onto a bowl-shaped metal substrate. Diamond grinding wheels are commonly used in concrete grinders to grind materials such as concrete, granite, marble, and other stones. To improve grinding efficiency, a corrugated tooth grinding wheel is available. Summary of the Invention

[0003] In view of this, the technical problem to be solved by this utility model is to provide a corrugated tooth grinding wheel, which solves the problem of low grinding efficiency of existing grinding wheels.

[0004] To solve the above-mentioned technical problems, this utility model discloses a corrugated tooth grinding wheel, comprising: a base; grinding teeth arranged in a ring array on the side of the base; a raised portion in the central region of the base, with a mounting hole in the center of the raised portion, and multiple grinding teeth at the edge of the opposite side of the raised portion on the base, the grinding surface of the grinding teeth being fan-shaped, and inclined surfaces on both sides of the grinding teeth.

[0005] Furthermore, the aforementioned substrate is provided with 15 spaced-apart grinding teeth.

[0006] Furthermore, the centerline of the chip removal groove formed between the aforementioned grinding teeth does not pass through the center of the base.

[0007] Furthermore, the inclination angle of the two inclined surfaces of the aforementioned grinding teeth ranges from 20° to 60°.

[0008] Furthermore, the thickness of the aforementioned grinding teeth is greater than the thickness of the substrate.

[0009] Compared with the prior art, this application can achieve the following technical effects: This invention features inclined surfaces on both sides of the grinding teeth, which expands the volume of the chip removal groove, facilitating chip removal and heat dissipation. The cross-sectional shape of the grinding teeth and the shape of the chip removal groove form a continuous corrugated pattern. Furthermore, the outer edge of the grinding teeth is wide while the inner edge is narrow. The centrifugal force during grinding can smoothly remove the chips, reducing the risk of chips being repeatedly ground and thus reducing the grinding performance of the grinding wheel.

[0010] 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

[0013] The following will describe in detail the implementation of this application with reference to the accompanying drawings and embodiments, so that the implementation process of how this application uses technical means to solve technical problems and achieve technical effects can be fully understood and implemented accordingly.

[0014] Please refer to Figure 1 and Figure 2 , Figure 1 This is a schematic diagram of a grinding wheel according to one embodiment of the present invention; Figure 2 This is a cross-sectional schematic diagram of the grinding wheel according to one embodiment of the present invention.

[0015] A corrugated tooth grinding wheel includes: a base 1; grinding teeth 2 arranged in a ring array on the side of the base 1; a raised portion 3 in the central region of the base 1, a mounting hole 4 in the center of the raised portion 3, and multiple grinding teeth 2 at the edge of the opposite side of the raised portion 3 on the base 1, the grinding surface of the grinding teeth 2 is fan-shaped, and inclined surfaces 5 are provided on both sides of the grinding teeth 2.

[0016] The substrate 1 has 15 spaced grinding teeth 2. As the number of grinding teeth 2 increases, the chip removal groove 6 also increases accordingly, which can greatly improve the chip removal performance.

[0017] The chip removal groove 6 formed between the grinding teeth 2 does not pass through the center of the base 1. The chips generated by the rotation of the grinding teeth 2 are diffused outward by centrifugal force, and the chip removal groove 6, which is biased towards the center of the base 1, removes chips more smoothly.

[0018] The inclination angle of the two inclined surfaces of the grinding tooth 2 ranges from 20° to 60°. If the inclination angle is too small, the chip removal effect of the ripples will be insignificant. If the inclination angle is too large, the area of ​​the grinding surface will be reduced, which will affect the grinding efficiency.

[0019] The thickness of the grinding tooth 2 is 3mm, the thickness of the base 1 is 2mm, the diameter of the base 1 is 50.5mm, and the height of the grinding wheel is 13.5mm. The grinding tooth 2 is formed by pressing a mixture of diamond abrasive, metal binder powder, etc. into a mold with a corrugated cavity by the mechanical force of a hydraulic press. Densification is achieved through mechanical interlocking and plastic deformation between particles, forming a grinding tooth 2 blank with a clear corrugated profile. The strength is then enhanced by sintering and curing. Finally, the grinding tooth is welded to the base.

[0020] The present invention sets the two sides of the grinding tooth 2 as inclined surfaces 5, which can expand the volume of the chip removal groove 6, making it easier to remove chips and dissipate heat. The cross-sectional shape of the grinding tooth 2 and the shape of the chip removal groove 6 form a continuous corrugated shape. Furthermore, the outer edge of the grinding tooth 2 is wide and the inner edge is narrow. The centrifugal force during grinding can smoothly remove the chips, reducing the possibility of chips being repeatedly ground and reducing the grinding performance of the grinding wheel.

[0021] The foregoing description illustrates and describes several preferred embodiments of the present invention. However, as previously stated, it should be understood that the present invention is not limited to the forms disclosed herein and should not be construed as excluding other embodiments. It can be used in various other combinations, modifications, and environments, and can be altered within the scope of the inventive concept described herein through the foregoing teachings or techniques or knowledge in related fields. Any modifications and variations made by those skilled in the art that do not depart from the spirit and scope of the present invention should be within the protection scope of the appended claims.
