Description

Technical Field

[0001] This utility model relates to the technical field of abrasive wheels, specifically an abrasive wheel with multiple heat dissipation structures. Background Technology

[0002] Abrasive wheels are a common polishing tool, widely used in machining, metal surface treatment, wood processing and many other fields.

[0003] A search revealed that a typical example of an existing abrasive wheel is disclosed in publication number CN201009172Y, which describes an abrasive wheel consisting of a base, a fixing ring at the center of the base, and abrasive sheets adhered to the front of the base. A reinforcing ring, composed of two layers of fiber mesh with a diameter of 0.5-0.8 mm, is added around the back of the fixing ring on the base, and is also covered with a protective film. During the high-speed rotation of the abrasive wheel, the impact force on the abrasive sheets is greatly reduced when transmitted to the reinforcing ring, keeping the abrasive wheel fixed and balanced. Simultaneously, the addition of a fiber film to the base improves the adhesion between the reinforcing ring and the base, preventing the reinforcing ring from detaching and enhancing the stability and safety of the abrasive wheel.

[0004] In summary, existing abrasive wheels generate a large amount of heat when rotating at high speed and rubbing against the workpiece surface. If heat is not dissipated in time, the adhesive on the abrasive wheel will soften, wear will be accelerated, and the service life of the abrasive wheel will be reduced. Furthermore, the heat transferred to the workpiece may cause defects such as thermal deformation and changes in hardness on the workpiece surface, affecting the processing accuracy and quality. To address these issues, existing equipment needs to be improved. Utility Model Content

Existing abrasive wheels generate a large amount of heat during high-speed rotation and friction with the workpiece surface. If heat is not dissipated in time, the adhesive on the abrasive wheel will soften, wear will accelerate, and the service life of the abrasive wheel will be reduced. Furthermore, heat transferred to the workpiece may cause defects such as thermal deformation and changes in hardness on the workpiece surface.

[0006] Issues affecting machining accuracy and quality.

[0008] A mounting threaded cylinder is provided on the rear side of the mounting hole in the middle of the chassis, and multiple strip channels are opened at an angle on the front of the chassis. At the same time, a fan-shaped channel is opened between adjacent strip channels. A mounting component is provided on the front side of the chassis, and the mounting component is threadedly connected to the corresponding threaded hole on the chassis by mounting bolts. At the same time, a sanding cloth blade is provided on the front of the mounting component.

[0009] Preferably, the mounting assembly includes a connecting plate, and the connecting plate has multiple through holes equidistantly arranged on its outer side. At the same time, an inner positioning frame and an outer positioning frame are respectively provided in the middle and on the outer side of the front of the connecting plate.

[0010] Preferably, both the connecting plate and the chassis are made of metal, and the outer sides of the connecting plate and the chassis are coated with a heat dissipation coating, which is a mixture of alumina ceramic powder and high-temperature resistant binder.

[0011] By adopting the above technical solution, the heat absorbed by the surface of the connecting plate and the chassis can be quickly conducted away, thereby reducing the surface temperature of the abrasive cloth blades.

[0012] Preferably, the inner positioning frame is a T-shaped structure, and the through hole in the middle of the inner positioning frame is positioned corresponding to the mounting hole. At the same time, the outer side of the inner positioning frame is connected to one side of the abrasive blade by an adhesive.

[0014] Preferably, the position of the heat dissipation through hole corresponds to the middle position of the connection between the strip channel and the fan-shaped channel;

[0015] By adopting the above technical solution, the heat generated by the abrasive cloth blades during operation is dissipated through the gas flowing in the heat dissipation holes.

[0016] Compared with the prior art, the beneficial effects of this utility model are: the abrasive wheel with multiple heat dissipation structures,

[0017] To address the issues that existing abrasive wheels generate significant heat during high-speed rotation and friction with the workpiece surface, leading to softening of the abrasive wheel's adhesive, accelerated wear, and reduced wheel lifespan if not properly dissipated, and the potential for heat transfer to the workpiece causing surface defects such as thermal deformation and hardness changes, thus affecting machining accuracy and quality, this application utilizes a combination of strip-shaped channels, fan-shaped channels, and heat dissipation holes to form a heat dissipation channel. This allows air circulation, carrying away internal heat. Furthermore, a heat dissipation coating and through holes are incorporated. Through this multi-layered heat dissipation structure, the heat generated by the abrasive wheel during grinding can be quickly and effectively dissipated from multiple directions and levels, improving heat dissipation during use.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figure 1-4 This utility model provides a technical solution: a sand with multiple heat dissipation structures.

[0025] Cloth wheel, according to Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, a mounting threaded cylinder 2 is provided on the rear side of the mounting hole in the middle of the chassis 1, and multiple strip channels 3 are obliquely opened on the front of the chassis 1. At the same time, a fan-shaped channel 4 is opened between adjacent strip channels 3. A mounting component is provided on the front side of the chassis 1, and the mounting component is threadedly connected to the corresponding threaded hole 5 on the chassis 1 by mounting bolts 8. The mounting bolts 8 make the rear side of the connecting plate 6 fit and connect with the front side of the chassis 1. At the same time, the strip channels 3 and the fan-shaped channel 4 form a heat dissipation channel to improve the heat dissipation effect of the connecting plate 6 and the chassis 1. Abrasive blades 12 are provided on the front of the mounting component.

[0026] Specifically, the mounting components include a connecting plate 6, both of which are made of metal. The outer surfaces of the connecting plate 6 and the base 1 are coated with a heat-dissipating coating, which is a mixture of alumina ceramic powder and a high-temperature resistant adhesive. This coating quickly dissipates heat from the abrasive blades 12 onto the upper surfaces of the connecting plate 6 and the base 1, reducing the surface temperature of the abrasive blades 12. Multiple through holes 7 are equidistantly spaced on the outer surface of the connecting plate 6. These through holes allow heat from the abrasive blades 12 located inside the outer positioning frame 10 to dissipate, preventing the adhesive from softening at high temperatures and causing the abrasive blades 12 to detach from the outer positioning frame 10. This extends the lifespan of the abrasive wheel and reduces operating costs. Additionally, inner positioning frames 9 are located in the center and on the outer side of the front of the connecting plate 6. The outer positioning frame 10 and the inner positioning frame 9 are T-shaped structures. The through hole in the middle of the inner positioning frame 9 corresponds to the position of the mounting hole. The outer side of the inner positioning frame 9 is connected to one side of the abrasive blade 12 by adhesive. The outer positioning frame 10 is located on the front side of the through hole 7, and the inner side of the outer positioning frame 10 is connected to the other side of the abrasive blade 12 by adhesive. The front of the connecting plate 6 is provided with heat dissipation through holes 11 at equal intervals between the inner positioning frame 9 and the outer positioning frame 10. The position of the heat dissipation through holes 11 corresponds to the middle position of the connection between the strip channel 3 and the fan channel 4. The heat dissipation through holes 11 form a heat dissipation channel with the strip channel 3 and the fan channel 4, so that the heat on the abrasive blade 12 is dissipated through the airflow flowing in the heat dissipation through holes 11, thereby improving the heat dissipation effect.

[0027] In use, first attach the connecting plate 6 to the base plate 1, then rotate the mounting bolt 8 through the connecting plate 6.

[0028] The abrasive blade 12 is threaded into the corresponding threaded hole 5 on the chassis 1. Then, the two sides of the abrasive blade 12 are connected to the inner positioning frame 9 and the inner side of the outer positioning frame 10 respectively by adhesive, so that the abrasive blade 12 is fixed inside the mounting assembly. When it rotates at high speed and rubs against the workpiece surface, the heat generated on the abrasive blade 12 is discharged into the strip channel 3 and the fan channel 4 through the heat dissipation hole 11 and the through hole 7 for heat exchange. The airflow generated by the rotation enters the strip channel 3 and the fan channel 4 to dissipate the heat. The connecting plate 6 and the outer side of the chassis 1 are coated with a heat dissipation coating. Since the abrasive blade 12 is tightly connected to the connecting plate 6, and the connecting plate 6 is tightly connected to the chassis 1, the heat can be effectively transferred and the generated heat can be quickly and effectively dissipated, ensuring that the abrasive wheel and the workpiece work within a suitable temperature range.
