A diamond composite grinding disc

Abstract

This utility model discloses a diamond composite grinding disc, comprising a mounting substrate and a diamond grinding layer. Beneficial effects: The mounting substrate and the base post are integrally connected. The shear force generated during grinding is transferred to the base post through the insertion hole, and then to the mounting substrate through the base post. The base post, instead of the adhesive, bears most of the shear force, thus significantly improving its integrity and shear resistance, avoiding peeling, and enhancing stability in use. Simultaneously, the top surface of the mounting substrate is integrally connected to top fins, which expand the heat dissipation area of ​​the top surface of the mounting substrate. Part of the heat generated during grinding is transferred to the mounting substrate through the base post and dissipated outwards through the expanded top fins on the top surface of the mounting substrate, significantly improving heat dissipation performance. The base post also simultaneously increases its heat conduction area, further improving heat dissipation performance and avoiding cracking problems caused by different thermal expansion efficiencies between different materials, further enhancing stability and work efficiency in use.

Description

Technical Field

[0001] This utility model relates to the field of diamond grinding disc technology, and more specifically, to a diamond composite grinding disc. Background Technology

[0002] Diamond grinding discs are processing tools made by combining diamond as the abrasive with composite materials. They are used for grinding and can be used to process irregular shapes of materials such as stone, ceramics, glass, and floor tiles. They are suitable for stone polishing, beveling lines, and processing curved slabs and irregularly shaped stone. They can also be used for irregular processing, repair, and renovation of marble, concrete, cement floors, terrazzo, microcrystalline glass, artificial stone, floor tiles, glazed tiles, and vitrified tiles. They have strong grinding power, good durability, good softness, and good clarity and gloss, making them ideal stone grinding tools. The entire process is divided into four stages: coarse grinding, fine grinding, fine grinding, and polishing. The processed stone has a gloss of over 90°.

[0003] A search revealed application CN202123275019.1, entitled "A Grinding Disc for Diamond Composite Grinding." This application addresses the issue that existing diamond grinding discs often require stacking multiple discs for transport, making it difficult to retrieve individual discs and significantly impacting overall efficiency. By incorporating a wear-resistant layer, a corrosion-resistant layer, and a heat-insulating layer, the application proposes a method to significantly improve the grinding disc's performance when used for diamond composite grinding. The physical properties can improve the service life of the grinding disc to a certain extent, thereby significantly reducing the user's cost. However, the wear layer, corrosion-resistant layer and heat insulation layer in this application are simply stacked and fixed by adhesive. During grinding, the grinding surface is subjected to a large shear force, which can easily lead to excessive stress on the adhesive surface and delamination, affecting the safety and stability of use. At the same time, the broken pieces can be thrown out at high speed, causing injury. The heat conduction is affected by the heat insulation layer, which can easily lead to uneven thermal expansion between different materials, resulting in cracking and affecting the stability of use. Further improvements can be made.

[0005] To address the shortcomings of existing technologies, this invention provides a diamond composite grinding disc that has the advantages of stable and reliable structure, high heat dissipation efficiency, and safer use, thereby solving the problems mentioned in the background technology.

[0006] To achieve the advantages of stable and reliable structure, high heat dissipation efficiency, and safer use, the specific technical solution adopted by this utility model is as follows:

[0007] A diamond composite grinding disc includes a mounting substrate and a diamond grinding layer. The mounting substrate has a bottom post arranged on its bottom surface and a top fin on its top surface. The diamond grinding layer is bonded to the bottom of the mounting substrate. The top surface of the diamond grinding layer has an insertion hole corresponding to the bottom post position. The bottom post is inserted into the insertion hole. A fiber reinforcement layer is bonded between the diamond grinding layer and the mounting substrate.

[0008] Furthermore, both sides of the fiber reinforcement layer are fixedly bonded to the bottom surface of the mounting substrate and the top surface of the diamond grinding layer respectively by adhesive.

[0009] Furthermore, the outer wall of the bottom post and the inner wall of the insertion hole are fixedly bonded together with adhesive.

[0010] Furthermore, mounting holes are provided at the center of the mounting substrate, the fiber reinforcement layer, and the diamond grinding layer.

[0011] Furthermore, a reinforcing cylinder is integrally formed at the center of the top surface of the mounting base plate, located on the top surface of the mounting hole.

[0012] Furthermore, multiple sets of the bottom pillars are evenly arranged, and the bottom pillars and the mounting base plate are an integral structure.

[0013] Furthermore, the top fins are distributed in multiple sets at equal angles along the vertical center line of the mounting substrate, and the top fins and the mounting substrate are an integral structure.

[0014] Furthermore, the mounting substrate, fiber reinforcement layer, and diamond abrasive layer have the same diameter.

[0015] Compared with the prior art, the present invention provides a diamond composite grinding disc with the following advantages:

[0016] (1) This utility model adopts a mounting base, a bottom post, and a plug hole. The mounting base and the bottom post are integrally connected. When the diamond grinding layer is bonded and fixed to the mounting base, the bottom post is inserted into the plug hole on the top surface of the diamond grinding layer. At the same time, the diamond grinding layer and the mounting base, the plug hole and the bottom post are bonded by adhesive. The shear force generated during grinding is transmitted to the bottom post through the plug hole, and then to the mounting base through the bottom post. The bottom post bears most of the shear force instead of the adhesive, thereby significantly improving its integrity and shear resistance, avoiding peeling, and improving the stability of use. At the same time, the top surface of the mounting base is integrally connected to the top fins. The top fins expand the heat dissipation area of ​​the top surface of the mounting base. Part of the heat generated during grinding is transferred to the mounting base through the bottom post and dissipated outward through the expanded top fins on the top surface of the mounting base, which significantly improves the heat dissipation performance. The bottom post also increases the heat conduction area, further improving the heat dissipation performance and avoiding cracking caused by different thermal expansion efficiencies between different materials. This further improves the stability of use and work efficiency.

[0017] (2) The present invention adopts a fiber reinforcement layer, which is located between the mounting substrate and the diamond grinding layer. It is bonded together with the mounting substrate and the diamond grinding layer by an adhesive. When the diamond grinding layer breaks, the fiber reinforcement layer can hold the broken diamond grinding layer fragments to prevent them from flying out and injuring people, thereby improving the safety of use and further improving the stability of use.

These drawings are mainly used to illustrate the embodiments and can be used in conjunction with the relevant descriptions in the specification to explain the operating principles of the embodiments. With reference to these contents, those skilled in the art should be able to understand other possible implementation methods and the advantages of the present invention. The components in the figures are not drawn to scale, and similar component symbols are usually used to represent similar components.

[0026] According to an embodiment of the present invention, a diamond composite grinding disc is provided.

[0027] The present invention will now be further described in conjunction with the accompanying drawings and specific embodiments, such as... Figure 1-4 As shown, a diamond composite grinding disc according to an embodiment of the present invention includes a mounting substrate 1 and a diamond grinding layer 7. The mounting substrate 1 has bottom posts 4 arranged on its bottom surface. The mounting substrate 1 is made of carbon ceramic material, which has strong thermal conductivity and high strength. A top fin 6 is formed on the top surface of the mounting substrate 1. The top fin 6 has a sheet-like structure. The diamond grinding layer 7 is bonded to the bottom of the mounting substrate 1. The diamond grinding layer 7 is formed by bonding diamond and abrasive, and is a common material in the art. Insertion holes 8 are formed on the top surface of the diamond grinding layer 7 corresponding to the positions of the bottom posts 4. The number of insertion holes 8 is the same as the number of bottom posts 4. The bottom posts 4 are inserted into the insertion holes 8. A fiber reinforcement layer 5 is bonded between the diamond grinding layer 7 and the mounting substrate 1. The fiber reinforcement layer 5 is made of carbon fiber mesh. The densely distributed mesh on its surface facilitates the adhesive bonding of the mounting substrate 1 and the diamond grinding layer 7. Simultaneously, the carbon fiber mesh has high strength and is not easily broken. The mounting substrate 1 and the bottom posts 4 are integrally connected. When fixed, the base post 4 is inserted into the insertion hole 8 on the top surface of the diamond grinding layer 7. At the same time, the diamond grinding layer 7 and the mounting base 1, and the insertion hole 8 and the base post 4 are bonded together with adhesive. The shear force generated during grinding is transferred to the base post 4 through the insertion hole 8, and then to the mounting base 1 through the base post 4. The base post 4 bears most of the shear force instead of the adhesive, thereby significantly improving its integrity and shear resistance, avoiding peeling, and improving the stability of use. Meanwhile, the top fin 6 is integrally connected to the top surface of the mounting base 1. The top fin 6 expands the heat dissipation area of ​​the top surface of the mounting base 1. Part of the heat generated during grinding is transferred to the mounting base 1 through the base post 4 and dissipated outward through the expanded top fin 6 on the top surface of the mounting base 1, significantly improving the heat dissipation performance. The base post 4 also increases the heat conduction area, further improving the heat dissipation performance and avoiding cracking caused by different thermal expansion efficiencies between different materials, further improving the stability of use and working efficiency.

[0028] In one embodiment, both sides of the fiber reinforcement layer 5 are fixedly bonded to the bottom surface of the mounting substrate 1 and the top surface of the diamond grinding layer 7 respectively by adhesive. The fiber reinforcement layer 5 is located between the mounting substrate 1 and the diamond grinding layer 7, and is bonded together with the mounting substrate 1 and the diamond grinding layer 7 by adhesive. When the diamond grinding layer 7 breaks, the fiber reinforcement layer 5 can hold the broken pieces of the diamond grinding layer 7 to prevent them from flying out and injuring people, thereby improving the safety of use and further improving the stability of use.

[0029] In one embodiment, the outer wall of the base post 4 and the inner wall of the insertion hole 8 are fixedly bonded by adhesive, which expands the bonding area and improves the bonding strength and stability.

[0030] In one embodiment, mounting holes 2 are provided at the center of the mounting substrate 1, the fiber reinforcement layer 5, and the diamond grinding layer 7. The mounting holes 2 facilitate the connection and installation of a grinding machine, which is a common structure in the art.

[0031] In one embodiment, a reinforcing cylinder 3 is integrally formed at the center of the top surface of the mounting base 1, located on the top surface of the mounting hole 2. The reinforcing cylinder 3 increases the structural thickness at the mounting hole 2 location, improves the local strength, and thus reduces the problem of damage at the mounting point.

[0032] In one embodiment, multiple sets of bottom posts 4 are evenly arranged, and the bottom posts 4 and the mounting base plate 1 are an integral structure, which facilitates heat conduction, increases connection strength, and makes production more convenient.

[0033] In one embodiment, multiple sets of top fins 6 are distributed at equal angles along the vertical center line of the mounting substrate 1, and the top fins 6 and the mounting substrate 1 are an integral structure, which facilitates heat conduction, increases connection strength, and makes production more convenient.

[0034] In one embodiment, the mounting substrate 1, fiber reinforcement layer 5, and diamond abrasive layer 7 have the same diameter to avoid misalignment and improve the appearance quality of the product.

[0035] Working principle:

[0036] The mounting base 1 and the base post 4 are integrally connected. When the diamond grinding layer 7 is bonded and fixed to the mounting base 1, the base post 4 is inserted into the insertion hole 8 on the top surface of the diamond grinding layer 7. Simultaneously, the diamond grinding layer 7 and the mounting base 1, as well as the insertion hole 8 and the base post 4, are bonded together with adhesive. The shear force generated during grinding is transferred to the base post 4 through the insertion hole 8, and then to the mounting base 1 through the base post 4. The base post 4 bears most of the shear force, significantly improving its integrity and shear resistance, preventing peeling, and enhancing stability during use. Furthermore, the top surface of the mounting base 1 is integrally connected to the top fin 6, which expands the heat dissipation area of ​​the top surface of the mounting base 1. Part of the heat generated during grinding is dissipated through the top fin 6. The heat dissipation is transferred from the base column 4 to the mounting substrate 1 and dissipated outward through the top fins 6 extending from the top surface of the mounting substrate 1, significantly improving heat dissipation performance. The base column 4 also increases the heat conduction area, further improving heat dissipation performance and avoiding cracking problems caused by different thermal expansion efficiencies between different materials. This further improves the stability and efficiency of use. Meanwhile, the fiber reinforcement layer 5 is located between the mounting substrate 1 and the diamond grinding layer 7, and is bonded together with the mounting substrate 1 and the diamond grinding layer 7 by adhesive. When the diamond grinding layer 7 breaks, the fiber reinforcement layer 5 can hold the broken pieces of the diamond grinding layer 7 to prevent them from flying out and injuring people, thereby improving the safety and stability of use.
