Description

Technical Field

[0001] This utility model relates to the field of grinding wheels, and in particular to a high-strength heat-dissipating resin grinding wheel. Background Technology

[0002] Grinding wheels, also known as bonded abrasives, are abrasives formed by bonding ordinary abrasive grains together with a binder into a specific shape, mostly circular with a central through-hole, and possessing a certain strength. They generally consist of abrasive grains, a binder, and pores; these three parts are often referred to as the three essential elements of bonded abrasives. Based on different binders, common types include ceramic grinding wheels, resin grinding wheels, and rubber grinding wheels. Among the various types of abrasives, grinding wheels are the most widely used and extensively applied. They rotate at high speeds and can perform roughing, semi-finishing, and finishing grinding on the outer and inner diameters, planes, and various profiles of metal or non-metal workpieces.

[0003] Current resin grinding wheels generally consist of a resin wheel body structure. While their structure is simple and they can basically achieve the grinding function, their functionality is relatively limited. Resin grinding wheels have poor strength, making them prone to cracking or even instantaneous breakage during high-speed grinding. The flying fragments can cause injury to operators. Furthermore, the friction between the grinding wheel and the workpiece during grinding generates and accumulates a large amount of heat. Resin grinding wheels have poor heat dissipation, easily leading to thermal stress cracking due to excessive temperature. The large amount of grinding debris produced during grinding can easily cause clogging, affecting processing efficiency. The product quality is generally average, and the service life is short, failing to meet current needs. Therefore, it is necessary to research a new technical solution to improve current resin grinding wheels. Utility Model Content

[0004] In view of the above, this utility model addresses the shortcomings of existing technologies and its main objective is to provide a high-strength heat-dissipating resin grinding wheel. This effectively solves the problems of existing resin grinding wheels, such as limited functionality, poor strength, susceptibility to cracking or even instantaneous breakage during high-speed grinding, resulting in high-speed flying fragments that can injure operators, the generation and accumulation of heat during grinding due to friction between the grinding wheel and the workpiece, the poor heat dissipation of resin grinding wheels leading to thermal stress cracking due to excessive temperature, the accumulation of grinding debris causing blockages and affecting processing efficiency, and the generally low quality and short service life of the products.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A high-strength heat-dissipating resin grinding wheel includes a body and a mounting part. The body has spiral grooves on both sides, with two symmetrically arranged spiral grooves, each with a trapezoidal cross-section. This significantly increases the contact area between the grinding wheel and air, accelerating heat dissipation during grinding. It guides airflow along a spiral path, further facilitating heat dissipation, reducing the risk of grinding burns, and effectively removing grinding debris to prevent clogging and improve chip removal efficiency. It also enhances the grinding wheel's noise reduction effect. Multiple arc-shaped through-slots are formed along both sides of the body, evenly spaced circumferentially. These arc-shaped through-slots are not connected to the spiral grooves. The arrangement of these arc-shaped through-slots improves the grinding wheel's heat dissipation and noise reduction performance, enhancing product quality and extending its service life. The body includes a resin grinding wheel base layer, a reinforcing frame, a first flame-retardant layer, a second flame-retardant layer, and a first reinforcing layer. The second reinforcing layer is embedded in the resin grinding wheel base. This reinforcing skeleton includes a reinforcing ring and multiple reinforcing portions extending outward from the reinforcing ring. These multiple reinforcing portions are evenly spaced circumferentially on the periphery of the reinforcing ring, effectively enhancing the product's strength and impact resistance. The first and second flame-retardant layers are stacked on both sides of the resin grinding wheel base, effectively enhancing the product's flame-retardant properties and preventing damage to the grinding wheel due to excessive temperature during use. The first and second reinforcing layers are stacked on the surfaces of the first and second flame-retardant layers, effectively enhancing the product's strength, improving grinding efficiency, extending its service life, and making it more durable. The mounting part is located at the center of the main body and has mounting holes and multiple fixing holes. The mounting holes are located at the center of the main body, and the multiple fixing holes are evenly spaced circumferentially around the mounting holes, which helps to enhance the structural stability when the product is installed with external parts.

[0007] As a preferred embodiment, the cross-section of the spiral groove is an isosceles trapezoidal structure, which can efficiently capture grinding debris, facilitate better removal of grinding debris, and improve chip removal efficiency.

[0008] As a preferred embodiment, the reinforcing frame is a high-strength alloy steel plate, which has high toughness, high mechanical strength, high tensile strength, is lightweight, and has good corrosion resistance and weather resistance.

[0009] As a preferred embodiment, the first flame-retardant layer is made of white fused alumina material. White fused alumina material has high hardness and good wear resistance, high temperature resistance, corrosion resistance, oxidation resistance and insulation properties, and is environmentally friendly and safe.

[0010] As a preferred option, the second flame-retardant layer is made of white fused alumina material. White fused alumina material has high hardness and good wear resistance, high temperature resistance, corrosion resistance, oxidation resistance and insulation properties, and is environmentally friendly and safe.

[0011] As a preferred embodiment, the first reinforcing layer is a carbon fiber reinforcing layer, which has high strength, is lightweight, and has good corrosion resistance, fatigue resistance, seismic resistance, high temperature resistance, and impact resistance.

[0012] As a preferred option, the second reinforcing layer is a carbon fiber reinforcing layer. The carbon fiber reinforcing layer has high strength, is lightweight, and has good corrosion resistance, fatigue resistance, seismic resistance, high temperature resistance, and impact resistance.

[0013] As a preferred embodiment, there are five reinforcing parts, which are evenly spaced circumferentially on the side surface of the reinforcing ring.

[0014] As a preferred embodiment, there are three fixing holes, which are evenly spaced around the mounting hole.

[0015] Compared with the prior art, this utility model has obvious advantages and beneficial effects. Specifically, as can be seen from the above technical solution:

[0016] By embedding a reinforcing skeleton into the resin grinding wheel base layer, the reinforcing skeleton includes a reinforcing ring and multiple reinforcing portions extending outward from the reinforcing ring. These multiple reinforcing portions are evenly spaced circumferentially on the periphery of the reinforcing ring. Combined with a first reinforcing layer and a second reinforcing layer, the product's strength is effectively enhanced, its impact resistance is improved, and the grinding wheel breakage prevents injury to operators. Furthermore, by providing spiral grooves on both sides of the main body, with each spiral groove having a trapezoidal cross-section, the product's heat dissipation, chip removal, and noise reduction performance are effectively enhanced. By forming multiple arc-shaped through slots through both sides of the main body, with these arc-shaped through slots evenly spaced circumferentially, the heat dissipation and noise reduction performance of the grinding wheel are improved. This allows for rapid heat dissipation, prevents thermal stress cracking of the grinding wheel, prevents chip clogging during grinding, improves grinding efficiency, enhances product quality, extends product lifespan, and meets current requirements.
