Description

Technical Field

[0001] This utility model relates to the field of heat dissipation grinding wheel. Background Technology

[0002] As a grinding tool, grinding wheels play an increasingly important role in the industrial field. They are used for rough grinding, semi-finish grinding, finish grinding, grooving, and cutting of the surfaces of metal or non-metal workpieces. Because they are rotating at high speeds, they need to withstand significant impact forces, thus requiring grinding wheels to possess high strength, impact resistance, heat resistance, and corrosion resistance.

[0003] A high-heat-dissipation diamond grinding wheel, disclosed in announcement number CN207155594U, includes a recovery box, a connecting water pipe, a heat-conducting pipe, a circulating pump, a condensate storage tank, a housing, a rotating rod, a long brush, and a short brush. The recovery box is installed on the lower side of the housing, the connecting water pipe is installed on the annular side of the housing, the heat-conducting pipe is installed on the left end face of the housing, the circulating pump is fixed on the upper side of the housing, the condensate storage tank is installed on the right side of the circulating pump, and the housing is installed on the outer side of the grinding wheel body. This design solves the problem of poor heat dissipation of the original diamond grinding wheel. The rotating rod is fixed on the inner side of the support plate, the long brush is fixed on the upper side of the rotating rod, and the short brush is fixed on the inner side of the long brush.

[0004] Existing high-heat-dissipation diamond grinding wheels have the following drawbacks: While existing technologies incorporate brush cleaning, the accumulation of debris on the grinding wheel surface takes a considerable amount of time. Simply cleaning the debris cannot quickly cool the grinding wheel, resulting in poor heat dissipation.

It is connected to an external water source through a water supply pipe and sprays water onto the grinding wheel through a spray nozzle to further dissipate heat. Attached Figure Description

[0026] like Figures 1 to 4 As shown, a heat-dissipating grinding wheel includes a protective shell 1, a grinding wheel 3, a mounting frame 4, an axial fan 5, a cooling device 6, and a water supply pipe 7. The protective shell 1 has an open side and several ventilation holes 2 on both sides. The grinding wheel 3 is located inside the protective shell 1. The mounting frame 4 is fixedly connected to both sides of the protective shell 1. The axial fan 5 is located inside the mounting frame 4, which is used to mount the axial fan 5. The through holes 2 on both sides of the protective shell 1 allow for heat dissipation while preventing foreign objects from entering the protective shell 1 during grinding and colliding with the axial fan 5, causing damage. The cooling device 6 is located on the side of the mounting frame 4 away from the protective shell 1 and, in conjunction with a semiconductor cooling chip, generates cool air to simultaneously dissipate heat from both sides of the grinding wheel. A power supply device 602 is located on the outside of the mounting frame 4 and supplies power to the semiconductor device. A water supply pipe 7 is fixedly connected to the outside of the protective shell 1. Water nozzles 8 are evenly distributed on the inside of the protective shell 1. The water nozzles 8 are connected to the water supply pipe 7. One end of the water supply pipe 7 is equipped with a water source connector 12. The water nozzles 8 do not contact the grinding wheel 3. The water supply pipe 7 is connected to an external water source and the water nozzles 8 spray onto the grinding wheel 3 to further dissipate heat. Several air vents 9 are evenly distributed on the top of the protective shell 1, and drainage holes 10 are evenly distributed on the bottom of the protective shell 1. The hot air generated during the heat dissipation process of the axial fan 5 and the semiconductor cooling chip 601 is dissipated from the protective shell 1 through the air vents 9. The liquid sprayed by the water nozzles 8 dissipates from the protective shell 1 through the drainage holes 10 after dissipating heat from the grinding wheel 3. Scrapers 11 are fixedly connected to both sides of the opening of the protective shell 1. The scrapers 11 can scrape off the waste on both sides of the grinding wheel 3 during use.
