Abstract
Description
Technical Field
[0001] This utility model relates to the field of abrasive belt technology, and in particular to a diamond abrasive belt. Background Technology
[0002] In many fields such as materials processing and machinery manufacturing, grinding is a key process to improve the surface quality and precision of workpieces, and grinding belts are widely used as an important consumable in the grinding process.
[0003] Currently, commonly available grinding belts have several shortcomings. Firstly, the abrasive in ordinary grinding belts has poor wear resistance, leading to rapid wear during prolonged grinding operations. This results in a short belt lifespan and frequent replacements, increasing production costs and reducing efficiency. Secondly, traditional grinding belts have poor adhesion to complex-shaped workpieces, making it difficult to ensure uniform grinding and causing uneven surface grinding, thus affecting the final quality of the workpiece. Furthermore, ordinary grinding belts generally have limited effectiveness on high-hardness materials (such as titanium alloys and other hard metals), failing to meet the requirements of high-precision grinding.
[0004] To overcome the shortcomings of existing grinding belts and meet the growing demand for high-precision and high-efficiency grinding, this application proposes a diamond grinding belt. Since diamond is a material with extremely high hardness and excellent wear resistance, applying diamond micropowder to the grinding belt can significantly improve its wear resistance and grinding accuracy. Utility Model Content
[0005] In view of the shortcomings of the prior art, the purpose of this utility model is to provide a diamond grinding belt, which aims to solve the technical problem that the grinding accuracy of ordinary grinding belts in the prior art needs to be improved.
[0006] To achieve the above objectives, the present invention adopts the following technical solution:
[0007] A diamond abrasive belt includes a belt body, the outer side of which is covered with a layer of diamond micro powder; the diamond micro powder layer is formed by mixing diamond micro powder with an adhesive and then adhering it to the belt body.
[0008] Furthermore, in the diamond grinding belt, the belt body includes a base fabric and a lining, and the diamond powder layer covers the base fabric.
[0009] Furthermore, in the diamond grinding belt, the base fabric is one of polyester fiber cloth, aramid fiber cloth, and glass fiber cloth.
[0010] Furthermore, in the diamond grinding belt, the liner includes an intermediate layer and an inner layer.
[0011] Furthermore, in the diamond grinding belt, the intermediate layer is rubber or foam.
[0012] Furthermore, in the diamond grinding belt, the inner layer is a fiber felt.
[0013] Furthermore, in the diamond grinding belt, the diamond powder is 2000 mesh to 5000 mesh diamond powder.
[0014] Furthermore, in the diamond grinding belt, the diamond micro powder layer is formed by mixing diamond micro powder with an adhesive and then covering the surface of the belt body by spraying, scraping, or roller coating.
[0015] Furthermore, in the diamond grinding belt, the mating interface of the base fabric is beveled.
[0016] Beneficial Effects: This utility model provides a diamond grinding belt. Compared with existing technologies, by covering the outer side of the belt body with a layer of diamond micro-powder, it can effectively improve grinding efficiency and grinding precision. Diamond micro-powder itself has high hardness and good wear resistance. Compared with the abrasive in ordinary grinding belts, it can cut materials more efficiently during the grinding process, quickly remove excess material from the workpiece surface, and significantly improve grinding efficiency and grinding precision compared with traditional grinding belts, thus making the product more in line with high grinding quality standards. Especially for hard materials, the diamond grinding belt provided by this application can provide high-precision grinding quality. Furthermore, by setting the belt body as a base cloth, intermediate layer, and liner, the impact force during grinding can be effectively buffered, reducing damage to the base cloth and micro-powder layer, and enabling the grinding belt to apply force more evenly, thereby further improving the service life and grinding effect of the grinding belt.

[0022] To make the objectives, technical solutions, and effects of this utility model clearer and more explicit, the present utility model is further described in detail below. It should be understood that the specific embodiments described herein are merely for explaining this utility model and are not intended to limit this utility model.
[0023] Please see Figure 1 and Figure 2 This utility model provides a diamond grinding belt. The accompanying drawings are for illustrative purposes only and are not proportional to actual products. The drawings only show structures relevant to the present utility model; some conventional structures are not specifically depicted. The fine dots filling the diamond micron layer 2 in the drawings are merely schematic; these dots do not actually represent diamond micron powder, as the particle size of diamond micron powder is in the micrometer range and cannot be directly observed with the naked eye.
[0024] The diamond abrasive belt includes a belt body 1, the outer side of which is covered with a diamond micro-powder layer 2; this diamond micro-powder layer is formed by mixing diamond micro-powder with an adhesive and then adhering it to the belt body. Typically, the belt body is annular.
[0025] Due to its extremely high hardness and excellent wear resistance, diamond micron powder significantly improves grinding efficiency when used as an abrasive in grinding belts. Especially when grinding hard materials, ordinary abrasives wear out quickly and have low grinding efficiency, while diamond micron powder can easily grind hard materials due to its high hardness, greatly shortening grinding time. Furthermore, its excellent wear resistance ensures that the abrasive does not easily fall off or wear during long-term use, guaranteeing the stability of grinding accuracy.
[0026] The aforementioned adhesive enables the diamond micropowder to adhere firmly to the outer side of the belt, ensuring that the micropowder will not easily fall off during the grinding process. Furthermore, the adhesive fills the gaps between the diamond micropowder particles, enhancing the integrity and stability of the diamond micropowder layer.
[0027] Preferably, the adhesive is an epoxy resin adhesive, which, when mixed with diamond micro powder, forms tight chemical bonds during the curing process, greatly enhancing the bonding force between the micro powder and the belt, ensuring that the micro powder layer can still work stably even when the grinding belt is running at high speed and under high pressure.
[0028] It should be noted that this utility model claims protection for the structure of the diamond grinding belt itself, and therefore does not limit the specific ratio of adhesive and diamond powder. In practical applications, the grinding layer formed by attaching diamond powder to the outside of the belt body with adhesive is the "diamond powder layer" referred to in this utility model.
[0029] Furthermore, the belt body 1 includes a base fabric 11 and a liner 12, with the diamond micron powder layer covering the base fabric. The base fabric bears the main tensile and frictional forces, and its high strength and abrasion resistance prevent the belt body from tearing or breaking during use. The liner serves to cushion, insulate, and protect the base fabric. In addition, the liner can distribute pressure, reduce heat transfer, and slow down the wear and aging rate of the base fabric.
[0030] Preferably, the base fabric is one of polyester fiber cloth, aramid fiber cloth, or glass fiber cloth. The base fabric is the fundamental supporting structure of the abrasive belt, and different base fabric materials can impart different properties to the abrasive belt. Polyester fiber cloth base fabric is low in cost and high in strength; aramid fiber cloth base fabric is high in strength and resistant to high temperatures; glass fiber cloth base fabric has good insulation and strong chemical stability. These properties allow the abrasive belt to be used in various scenarios, such as abrasive belts with aramid fiber cloth base fabric for grinding aerospace parts, which can withstand high temperatures and high stress; and abrasive belts with glass fiber cloth base fabric for grinding electronic components, which can avoid the effects of static electricity.
[0031] Furthermore, the liner 12 includes an intermediate layer 121 and an inner layer 122. Further configuring the liner as an intermediate and inner layer helps to further improve the cushioning effect, optimize heat dissipation performance, enhance structural stability, and protect the base fabric.
[0032] Specifically, the intermediate layer 121 is made of rubber or foam. Rubber or foam has good elasticity, which helps improve the cushioning effect and ensures uniform force application during the grinding process. During grinding, the grinding belt contacts the workpiece surface, generating impact forces due to pressure and relative motion. The rubber or foam intermediate layer acts as a buffer, effectively absorbing and dispersing these impact forces, reducing damage to the base fabric and diamond powder layer. The good flexibility of rubber or foam allows the grinding belt to better conform to the surface of workpieces of various shapes. Especially when grinding irregularly shaped workpieces, the rubber or foam can deform with the undulations of the workpiece surface, allowing the diamond powder layer to contact the workpiece evenly, ensuring uniform distribution of grinding force, avoiding localized over-grinding or under-grinding, thereby improving the grinding accuracy and surface quality of the workpiece.
[0033] Furthermore, the inner layer 122 is a fiber felt (e.g., polyester fiber felt, aramid fiber felt, glass fiber felt, etc.). The fiber felt has a soft texture and a certain degree of elasticity, which facilitates the installation of the grinding belt on the grinding equipment and also allows for a more uniform distribution of pressure when the grinding belt contacts the workpiece surface, thereby further improving the grinding accuracy.
[0034] Furthermore, the diamond micro powder is 2000 to 5000 mesh diamond micro powder. For materials with high hardness and brittle texture, such as cemented carbide and ceramics, 2000-5000 mesh micro powder can effectively cut the material while avoiding surface cracks caused by excessively large particles; for materials with low hardness and good toughness, such as non-ferrous metals like copper and aluminum, fine-grained micro powder can better control surface quality and prevent defects such as scratches and deformation during the grinding process.
[0035] Furthermore, the diamond micron powder layer is formed by mixing diamond micron powder with an adhesive and then applying it to the surface of the belt through spraying, scraping, or roller coating. These coating methods allow for effective control of parameters such as coating thickness and uniformity during operation. For example, by adjusting parameters such as spraying pressure, scraper height, and roller rotation speed, the quality of the micron powder layer can be ensured to remain stable.
[0036] Furthermore, the interface 20 between the diamond micron powder layer and the base fabric is beveled. Compared to a flat joint, the beveled joint increases the contact area at the interface. During the joining process, the adhesive can fill a larger area, making the bond between the base fabric and the interface stronger. When the grinding belt operates at high speed and is under high tension, the larger contact area can better disperse the tensile force, reduce the risk of breakage at the interface, and extend the service life of the grinding belt. In addition, the beveled joint provides a smoother interface transition, and when the grinding belt passes over the workpiece surface, there will be no significant grinding differences due to abrupt changes in thickness at the interface, ensuring the uniformity of grinding.
[0037] In practical applications, the diamond grinding layer, base fabric, intermediate layer and inner layer mentioned above can be connected together by adhesive bonding.
[0038] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. It is understood that those skilled in the art can make equivalent substitutions or modifications based on the technical solution and inventive concept of the present utility model, and all such modifications or substitutions should fall within the protection scope of the present utility model.
