Description

Technical Field

[0001] The present application relates to the technical field of water grinding discs, and in particular to a high-strength diamond water grinding disc. Background Art

[0002] Existing diamond water grinding discs such as Figure 7 As shown, it is mainly composed of a grinding disc 1 and a grinding block 2. The grinding block is usually in a rectangular shape and is evenly hot-melted and arranged on the surface of the grinding disc. With this arrangement, when the grinding disc rotates at high speed, the grinding block needs to withstand a large circumferential resistance, which challenges the connection strength between the grinding block and the grinding disc and makes it easy to fall off. Therefore, how to enhance the connection stability between the grinding block and the grinding disc has become an urgent problem to be solved. Utility Model Content

[0003] The problem to be solved by this application is that the existing diamond water grinding disc is mainly composed of a grinding disc and a grinding block. The grinding block is a rectangular parallelepiped hot-melt on the surface of the grinding disc. However, when the grinding disc rotates at high speed, the grinding block is easily fallen off due to the large circumferential resistance.

[0004] In order to solve the above technical problems, the present application provides a high-strength diamond water grinding disc, including a grinding disc for supporting and installing and positioning. The surface of the grinding disc is evenly and spaced apart along its circumferential direction with grinding blocks for cement floor polishing operations, and a conical edge protruding outward is provided on one side of the long side in the positive rotation direction of the grinding block.

[0005] Since the water grinding disc of the present application is designed with a grinding block with a tapered edge, the circumferential resistance borne during grinding can be reduced by the grinding block with a tapered edge, thereby solving the problem that the diamond water grinding disc in the prior art is mainly composed of a grinding disc and a grinding block, and the grinding block is in a rectangular shape and hot-melted to the surface of the grinding disc. However, when the grinding disc rotates at high speed, the grinding block is easily fallen off due to the large circumferential resistance. BRIEF DESCRIPTION OF THE DRAWINGS

[0014] The following will be combined with the drawings in the embodiments of this application to clearly and completely describe the technical solutions in the embodiments of this application. Obviously, the embodiments described are only part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application. Example

[0015] This application relates to a high-strength diamond water grinding disc, such as Figure 1-2 As shown, the water grinding plate includes a grinding disc 1 for supporting and installing and positioning. The surface of the grinding disc 1 is evenly and spaced apart along its circumferential direction with grinding blocks 2 for cement floor polishing operations. In order to reduce the resistance borne by the grinding block 2 when the grinding disc 1 rotates, a conical edge 3 protruding outward and having a triangular structure is designed on the side of the long side of the grinding block 2 in the positive rotation direction. In order to evenly disperse the resistance, the conical edge 3 is preferably an isosceles triangle structure, and the length of the conical edge 3 is in the ratio of the length of the long side of the grinding block 2 to the length of the long side of the grinding block 2 is 1:1.8~2.3. In order to effectively ensure the friction strength of the grinding block 2 and increase its grinding area, the ratio of the long side of the grinding block 2 to the radius of the grinding disc 1 is 1:1.5~1.8. Example

[0016] Based on the first embodiment, Figure 3 As shown, since the grinding block 2 may rotate forward or flip along with the grinding disc 1, in order to prevent the grinding block 2 from being subjected to greater resistance when the grinding block 2 is reversed, a conical edge 3 protruding outward and having a triangular structure is symmetrically designed on one side of the long sides of both sides of the grinding block 2, so that the resistance borne by the grinding block 2 can be effectively reduced regardless of the forward or reverse rotation. Example

[0017] On the basis of embodiment 1 or 2, Figure 4 As shown, in order to further reduce the resistance that the grinding block 2 bears as the grinding disc 1 rotates, the grinding block 2 is arranged obliquely on the surface of the grinding disc 1, and the angle between it and the vertical direction is 25 to 40 degrees, preferably an angle of 30 degrees, which can be effectively arranged without interfering with the holes on the surface of the grinding disc 1. Example

[0018] On the basis of any one of embodiments 1 to 3, Figure 5 As shown, the original grinding block 2 is divided into an outer stone and an inner stone that are arranged in an interlaced manner and of equal size. The outer stone and the inner stone are arranged parallel to and at intervals on the surface of the grinding disc 1. In order to be able to continue to maintain the complete grinding surface swept by the original grinding block 2 on the cement floor with the help of the combination of the outer stone and the inner stone, the lower end of the outer stone and the upper end of the inner stone are arranged in a front-to-back overlapping manner. The overlapping part is 2% to 5% of the length of the outer stone and the inner stone, and the length ratio between the outer stone, the inner stone and the original grinding block 2 is 1:1:1.90 to 1.95. Therefore, by shortening the length of the grinding block 2, the resistance it bears can be reduced, and the same area of ​​cement floor can still be swept. Example

[0019] On the basis of any one of embodiments 1 to 4, Figure 6 As shown, in order to reduce the falling off between the root of the grinding block 2 and the grinding disc 1, an inwardly recessed groove 4 for accommodating the grinding block 2 is formed at the upper portion of the grinding disc 1 corresponding to the grinding block 2. The ratio of the depth of the groove 4 to the thickness of the grinding block 2 is 1:5 to 8, preferably 1:7 with moderate depth and better connection strength.

[0020] During use, according to the roughness and resistance of the grinding site, a certain style of diamond water grinding disc in Examples 1 to 5 is selected as needed. Among them, due to the gradual complexity of the structures of Examples 1 to 5, the processing cost is gradually increased, resulting in a corresponding increase in the cost of use. At the same time, the wear resistance of the water grinding disc is gradually improved. Among them, the water grinding disc with the characteristics of Examples 1 to 5 has the highest wear resistance and resistance strength, which can effectively prevent the grinding block 2 from falling off during use. The grinding block is cast with wear-resistant diamond particles, and the grinding mesh numbers of the water grinding disc are generally 16, 30, 50, 80, and 120 meshes.
