[0001] The utility model relates to the technical field of abrasive tools, in particular to a wear-resistant grinding wheel structure that can avoid falling off and being damaged. Background Technique

[0002] Resin abrasive tools play an important role in the industrial and construction fields. Among them, abrasive tools mainly composed of ultra-thin resin cutting grinding wheels have the advantages of low cost, high cutting efficiency, good self-sharpening property, easy processing, etc., and are widely used. The storage and use convenience of resin grinding wheels have always been problems to be solved in industrial applications. The inconsistency of solidification conditions directly leads to the forming color and grinding ratio of the grinding wheel. At the same time, how to use the grinding wheel for a long time and effectively is a problem that users need to face.

[0003] Generally, in addition to the functions of distinguishing the use scenarios of the grinding wheel and the aesthetic function, colored grinding wheels can further distinguish their curing ability. Moreover, with the development of industrial technology, the use scenarios of grinding wheels cover sunny, rainy days, etc., and the humidity changes greatly. The abrasives in the grinding wheel are prone to react with the environmental moisture, resulting in a decrease in the grinding performance of the grinding wheel, and the grinding wheel is prone to fall off, be damaged and not wear-resistant. Content of the Utility Model

[0005] To achieve the above purpose, the utility model provides the following technical solution: a wear-resistant grinding wheel structure that can avoid falling off and being damaged, including a grinding wheel body. A fixing ring is arranged at the central part of the surface of the grinding wheel body, and an anti-rust coating is sprayed on the surface of the fixing ring. This anti-rust coating can effectively isolate external water vapor and at the same time can further improve the wear resistance of the ring hole; an elastic layer is arranged outside the fixing ring, and this elastic layer can solve the problem of the anti-rust coating falling off due to strong impact; the elastic layer and the grinding wheel body are linked to each other through a linking layer, and this linking layer can effectively reduce the damage degree of the fixing ring and the grinding wheel body during use.

[0006] Preferably, the anti-rust coating is a layer of octyl plating coating, and the coating thickness of this anti-rust coating is 0.3 - 0.5 MM.

[0007] Preferably, the elastic layer is a thermoplastic polyurethane elastomer, and the elasticity of this thermoplastic polyurethane elastomer can reduce the impact force on the grinding wheel body.

[0008] Preferably, the linking layer is a reinforced fiberglass mesh, and this linking layer can effectively link the elastic layer and the grinding wheel body to avoid the phenomenon of the elastic layer falling off.

[0009] Compared with the prior art, the beneficial effects of the present utility model are as follows: The wear-resistant grinding wheel structure that can avoid falling off and being damaged adds an anti-rust coating on the fixing ring of the grinding wheel body, selects a new octyl plating coating to act on the fixing ring to replace the traditional hot-dip galvanizing process, which does not fall off and has no bubbles, and can effectively isolate external water vapor. At the same time, the octyl coating can further improve the wear-resistant performance of the ring hole; after adding the anti-rust coating, in order to solve the problem of the coating falling off due to strong impact, an elastic layer is added to the outside of the fixing ring, and the selected material is thermoplastic polyurethane elastomer, which is linked to the grinding wheel body through a linking layer, and the selected material of the linking layer is an enhanced fiberglass mesh link, which can effectively reduce the damage degree of the ring hole and the grinding wheel body during use.

[0013] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. In addition, the terms "first", "second", "third", "upper, lower, left, right", etc. are only used for descriptive purposes and cannot be understood as indicating or implying relative importance. At the same time, in the description of the present utility model, unless otherwise clearly specified and limited, the terms "connected" and "linked" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium. Based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present utility model.

[0014] The structure of a wear-resistant grinding wheel structure provided by the present utility model that can avoid falling off and being damaged is as Figure 1As shown in the figure, it includes a grinding wheel body 1. A fixing ring 11 is arranged at the central part of the surface of the grinding wheel body 1. When the grinding wheel body 1 of the present utility model is manufactured, on the basis of the original colored grinding wheel product, the curing conditions are further optimized. It is selected to slowly increase the temperature starting from a curing temperature of 90°-92°. Small molecular weight impurities are further removed. When the curing temperature reaches 150°-175°, insulation is carried out according to actual conditions to increase the resin crosslinking degree. After continuously observing until the resin is completely crosslinked, the temperature is quickly increased to about 190° for secondary crosslinking. After a period of time, forced cooling is carried out. In this way, the resistance of the grinding wheel is improved through the curing means.

[0015] Further, as Figure 2 shown, an anti-rust coating 2 is sprayed on the surface of the fixing ring 11. This anti-rust coating 2 can effectively isolate external water vapor, and at the same time can further improve the wear resistance of the ring hole. The anti-rust coating 2 is a kind of octyl plating coating layer, and the coating thickness of this anti-rust coating 2 is 0.3-0.5MM; an elastic layer 3 is arranged on the outside of the fixing ring 11. This elastic layer 3 can solve the problem that the anti-rust coating 2 falls off due to strong impact. The elastic layer 3 is a thermoplastic polyurethane elastomer. The elasticity of this thermoplastic polyurethane elastomer can reduce the impact force received by the grinding wheel body 1; the elastic layer 3 and the grinding wheel body 1 are interconnected through a linking layer 4. This linking layer 4 can effectively reduce the damage degree of the fixing ring 11 and the grinding wheel body 1 during use. The linking layer 4 is a kind of reinforced fiberglass mesh. This linking layer 4 can effectively link the elastic layer 3 and the grinding wheel body 1 to avoid the phenomenon of the elastic layer 3 falling off.

[0016] The present utility model can select an effective anti-rust coating 2 and add it to the fixing ring 11 according to different climate characteristics to strengthen its anti-corrosion function. At the same time, in order to effectively strengthen the contact strength between the grinding wheel and the grinding machine, an elastic layer 3 is added. This elastic layer 3 is a thermoplastic polyurethane elastomer, which can improve the service life of the grinding wheel.

[0017] Working principle: During use, an anti-rust coating 2 is added to the fixing ring 11 of the grinding wheel body 1. A new type of octyl plating coating is selected to act on the fixing ring 11 to replace the traditional hot-dip galvanizing process. It does not fall off and has no bubbles, and can effectively isolate external water vapor. At the same time, the octyl coating can further improve the wear resistance of the ring hole; after adding the anti-rust coating 2, in order to solve the problem that the coating falls off due to strong impact, an elastic layer 3 is added to the outside of the fixing ring 11. The selected material is a thermoplastic polyurethane elastomer, which is linked to the grinding wheel body 1 through a linking layer 4. The selected material of the linking layer 4 is a reinforced fiberglass mesh for linking, which can effectively reduce the damage degree of the ring hole and the grinding wheel body 1 during use.
