[0031] The grinding wheel body 100 has a first surface 110 and a second surface 120, which are parallel to each other.

[0033] It can be understood that in the utility model example, the grinding wheel body 100 is mainly used for cutting materials, and the first surface 110 and the second surface 120 on the grinding wheel body 100 are parallel to each other. The first surface 110 and the second surface 120 of the grinding wheel body 100 are each provided with a convex core 200, the axis of the grinding wheel body 100 and the two convex cores 200 coincide with each other, and the grinding wheel body 100 and the two convex cores 200 are integrally formed. The two convex cores 200 are arranged in the middle part of the grinding wheel body 100, and in the process of high-speed rotation cutting of the grinding wheel body 100, the two convex cores 200 can better resist the bending stress caused by centrifugal force, thereby reducing the risk of fracture of the grinding wheel body 100 in the cutting process. On the other hand, the two convex cores 200 can increase the overall structural strength of the grinding wheel, so that it is not easy to deform when subjected to external force or impact. For the grinding wheel, increasing the overall structural strength can effectively reduce the instability caused by the thin material of the grinding wheel body 100, avoid excessive deformation or warping of the grinding wheel during use, reduce the probability of collapse of the grinding wheel body 100, and improve the safety of the grinding wheel.

[0034] In the prior art, in order to make the grinding wheel have a certain structural strength, the grinding wheel is usually not made too thin, so that more materials are needed for the manufacture of the grinding wheel, which is not conducive to reducing the cost of manufacturing the grinding wheel. In the embodiment of the utility model, the two convex cores can play a role in strengthening the structural strength, so that the grinding wheel body 100 can be thinned while ensuring a certain structural strength, reducing the materials required for manufacturing the grinding wheel, avoiding waste of materials required for manufacturing the grinding wheel, and being conducive to reducing the cost of manufacturing the grinding wheel. The grinding wheel of the embodiment of the utility model is a sheet-shaped resin cutting grinding wheel, and the grinding wheel body 100 and the two convex cores 200 are integrally formed, which can further improve the overall structural strength of the grinding wheel and ensure the safety of the grinding wheel.

[0035] Reference Figure 3 The grinding wheel of the embodiment of the utility model is symmetrical in the up-down direction, and the symmetrical grinding wheel can avoid stress concentration and uneven distribution during pressing, avoid collapse of the grinding wheel during pressing, and be conducive to improving the yield of the grinding wheel.

[0036] Reference Figure 1 And Figure 4The mounting hole 130 is provided on the grinding wheel body 100, the axis of the mounting hole 130 coincides with the axis of the grinding wheel body 100, and the mounting hole 130 penetrates the two convex cores 200. It can be understood that the mounting hole 130 is also called a center hole, and the mounting hole 130 penetrating the grinding wheel body 100 and the two convex cores 200 is used for the main shaft of the grinding equipment to pass through, so that the grinding equipment can position the grinding wheel, so that the main shaft of the grinding equipment can coincide with the axis of the grinding wheel, and ensure that the grinding equipment can stably drive the grinding wheel to rotate.

[0037] With reference to Figure 1 And Figure 4 The grinding wheel further comprises two flanges 210, the two flanges 210 are respectively arranged on the sides of the two convex cores 200 away from each other, and the axes of the two flanges 210 all coincide with the axis of the grinding wheel body 100.

On the one hand, the two flanges 210 can improve the overall structural strength of the grinding wheel, especially when rotating at high speed, the two flanges 210 can disperse and resist the stress concentration of the grinding wheel body 100 and the two convex cores 200 caused by the centrifugal force of high-speed rotation, and prevent the grinding wheel body 100 and the two convex cores 200 from being broken due to excessive stress.

[0039] As an embodiment of the present application, the thickness of the convex core 200 is greater than 0.4mm. It can be understood that the thickness of the convex core 200 needs to reach a certain value to effectively enhance the overall structural strength of the grinding wheel. In actual use, it is found that when the thickness of the convex core 200 is greater than or equal to 0.4mm, the overall structural strength of the grinding wheel can be effectively improved.

As a preferred embodiment of the present application, the ratio of the outer ring radius of the convex core 200 to the outer ring radius of the grinding wheel body 100 is 1 / 2. It can be understood that the ratio of the outer ring radius of the convex core 200 to the outer ring radius of the grinding wheel body 100 is 1 / 2, which not only ensures the structural strength of the grinding wheel body 100, but also ensures that the grinding wheel body 100 has sufficient grinding area, reduces the material required for grinding wheel manufacturing, and avoids material waste. Specifically, the outer ring radius of the convex core 200 is greater than the radius of the chuck of the clamping device in the grinding equipment.

[0041] As an embodiment of the present application, labels are attached to both convex cores 200. It can be understood that the labels print the model, specification, manufacturer and other identification information of the grinding wheel, which can help users to correctly match and identify when selecting and using the grinding wheel.

It can be understood that a chamfer 220 is provided on the end of each of the two convex cores 200 away from each other, i.e. a chamfer 220 is provided on the edge of the side of each of the two convex cores 200 away from each other, and the chamfer 220 at one end of the convex core 200 can prevent the edge of the convex core 200 from scratching the user, further improving the safety of the use of the grinding wheel.
