Description

Technical Field

[0001] The utility model relates to the technical field of explosion-proof grinding wheels, and particularly relates to an ultra-thin explosion-proof grinding wheel. Background Art

[0002] A grinding wheel, also known as a vitrified grinding tool, is a vitrified grinding tool in which ordinary abrasives are solidified into a certain shape (mostly circular with a through hole in the center) by a binder and have a certain strength. It generally consists of abrasive, binder and pores, and these three parts are often referred to as the three elements of a vitrified grinding tool. According to different classifications of binders, common ones include ceramic (binder) grinding wheels, resin (binder) grinding wheels, and rubber (binder) grinding wheels. The grinding wheel is the most widely used and most widely applied abrasive tool. When in use, it rotates at a high speed and can be used for rough grinding, semi-finishing and finishing of the outer circle, inner circle, plane and various profiles of metal or non-metal workpieces, as well as grooving and cutting. The characteristics of the grinding wheel are mainly determined by factors such as abrasive, grit size, binder, hardness, structure, shape and size.

[0003] When the existing grinding wheel works for a long time, a large amount of heat will be generated in the grinding wheel body. Due to poor heat dissipation, the accumulated heat not only affects the service life of the grinding wheel, but also increases the probability of explosion when the grinding wheel body rotates at a high speed. Content of the Utility Model

[0004] The main purpose of the utility model is to provide an ultra-thin explosion-proof grinding wheel to solve the problems mentioned in the background art.

[0005] To achieve the above purpose, the technical solution adopted by the utility model is as follows:

[0006] An ultra-thin explosion-proof grinding wheel includes a grinding wheel body. Spiral grooves are formed on both the front and rear surfaces of the grinding wheel body, and the spiral grooves on the front and rear surfaces are symmetrical to each other. A plurality of heat dissipation holes penetrating the grinding wheel body are formed in the spiral grooves. A thin plate-shaped strengthening support is embedded in the middle of the grinding wheel body. The strengthening support includes an outer ring and an inner ring, and support rods arranged between the outer ring and the inner ring. One end of the support rod is fixedly connected to the outer ring, and the other end of the support rod is fixedly connected to the inner ring.

[0007] Further, an annular wear-resistant body is pressed at the center of the grinding wheel body.

[0008] Further, a metal pressing ring is embedded inside the wear-resistant body, and an installation hole is provided at the center of the metal pressing ring.

[0009] Further, the material of the strengthening support is steel.

[0010] The working principle of the present utility model is as follows: When the grinding wheel body rotates at a high speed around the mounting hole, the spiral cutting grooves formed on the front and rear surfaces of the grinding wheel body and the heat dissipation holes penetrating the grinding wheel body allow air flow to pass through the heat dissipation holes along the spiral cutting grooves, continuously taking away the generated heat and improving the heat dissipation effect. Additionally, the strengthening bracket can enhance the strength of the grinding wheel body, thereby significantly extending its service life and reducing the probability of the grinding wheel body bursting.

[0011] Compared with the prior art, the present utility model has the following beneficial effects: It has good heat dissipation effect, high strength, can extend the service life of the grinding wheel, and reduce the probability of bursting when the grinding wheel rotates at a high speed.

[0017] As Figures 1-2 shown, an ultra-thin explosion-proof grinding wheel includes a grinding wheel body 3. Spiral cutting grooves 4 are formed on both the front and rear surfaces of the grinding wheel body 3, and the spiral cutting grooves 4 on the front and rear surfaces are symmetrical to each other. A plurality of heat dissipation holes 5 penetrating the grinding wheel body 3 are formed on the spiral cutting grooves 4. A thin plate-shaped strengthening bracket 6 is embedded in the center of the grinding wheel body 3. The strengthening bracket 6 includes an outer ring 61 and an inner ring 62, and support rods 63 arranged between the outer ring 61 and the inner ring 62. One end of each support rod 63 is fixedly connected to the outer ring 61, and the other end of each support rod 63 is fixedly connected to the inner ring 62.

[0018] Specifically, the material of the strengthening bracket 6 is steel.
