Description

Technical Field

[0001] The utility model relates to the technical field of grinding tools, in particular to a blade abrasive wheel. Background Art

[0002] Abrasive wheels play an important role in industrial production and are widely used in the processing of industrial products, mainly for grinding and polishing. Whether it is large-scale products such as cars, ships, and aviation equipment, or small items such as jade, shoe heels, and stainless steel products, a large number of abrasive wheels are required. Abrasive wheels belong to the category of industrial consumables and are also essential in industrial production.

[0003] An abrasive wheel is an extended product of coated abrasives, mainly used for grinding and polishing metals, especially having unique advantages in grinding and polishing thin-walled parts. However, the existing arrangement of abrasive wheels has poor effects and low efficiency under high-speed grinding conditions. After the abrasive wheel is used, there will be about 35% of the abrasive cloth remaining, resulting in low utilization rate of the abrasive cloth, and the continuous working time is only about 28 minutes. Summary of the Invention

[0004] In order to solve the problems of poor effects, low efficiency, low utilization rate of abrasive cloth blades, and short service life of the existing abrasive wheel under high-speed grinding conditions, the utility model provides a blade abrasive wheel. By providing fan-shaped abrasive cloth blades on the mounting ring surface, and partial coverage of adjacent abrasive cloth blades to form a grinding part, the grinding efficiency of the abrasive wheel is effectively improved, the utilization rate of the abrasive cloth blades is increased, and the service life of the product is extended.

[0005] In order to achieve the above purpose, the technical solution of the utility model is: a blade abrasive wheel, including a tray and abrasive cloth blades. The tray is sequentially provided with a hole ring, an annular fixing surface, and a mounting ring surface from the inside to the outside. The abrasive cloth blades are fixedly arranged on the mounting ring surface. The abrasive cloth blades are fan-shaped, and one end of the abrasive cloth blade gradually becomes narrower near the hole ring side. The abrasive cloth blades are circumferentially arranged on the mounting ring surface, and partial coverage of adjacent abrasive cloth blades forms a grinding part. The gradually narrowing end of the abrasive cloth blade is located below the adjacent abrasive cloth blade. The setting of the abrasive cloth blades significantly improves the effective utilization rate of the abrasive cloth blades during operation.

[0006] Further, the abrasive cloth blades are integrally formed.

[0007] Further, the mounting ring surface is inclined.

[0008] Further, the mounting ring surface is horizontal.

[0009] Further, the angle between the uncovered end of the abrasive cloth blade and the diameter line of the mounting ring surface is between 0° and 5°. This improves the utilization rate of the abrasive cloth blades, thereby improving the grinding efficiency and service life of the abrasive wheel.

[0010] Furthermore, the lowest height of the bottom surface of the installation toroidal surface is higher than the bottom surface height of the hole ring. When the installation toroidal surface is inclined downward, the lowest height of the bottom surface of the installation toroidal surface is higher than the bottom surface height of the hole ring, avoiding position interference between the abrasive cloth wheel and the power machine during the grinding process.

[0011] Furthermore, the annular fixing surface is an arc surface, with the inner side of the arc surface being lower and the outer side being higher.

[0012] Furthermore, the tray is a disc body made of fiberglass.

[0013] Through the above technical solutions, the beneficial effects of the present utility model are as follows:

[0014] In the present utility model, the designed fan-shaped abrasive cloth blades are gradually narrowed at one end close to the hole ring side, improving the utilization rate of the abrasive cloth blades. At the same time, the abrasive cloth blades are inclined and arranged on the installation toroidal surface, and adjacent abrasive cloth blades partially cover to form a grinding part. The angle between the uncovered end of the abrasive cloth blade and the diameter line of the installation toroidal surface is between 0° and 5°, increasing the contact area between the abrasive cloth blade and the workpiece to be ground, improving the grinding efficiency and service life of the abrasive cloth wheel, and significantly increasing the effective utilization rate of the abrasive cloth blades due to the shape setting of the abrasive cloth blades.

The abrasive cloth blades 2 are fixedly arranged on the mounting ring surface 5. The abrasive cloth blades 2 are integrally formed. The abrasive cloth blades 2 are fan-shaped rings, and one end of the abrasive cloth blades 2 gradually narrows near the side of the hole ring 3. The abrasive cloth blades 2 are circumferentially arranged on the mounting ring surface, and adjacent abrasive cloth blades 2 partially cover to form a grinding part. The gradually narrowing end of the abrasive cloth blades 2 is located below the adjacent abrasive cloth blades 2.

The contact area between the abrasive cloth blades 2 and the workpiece is increased. In the comparison between the blade abrasive cloth wheel and the louver abrasive cloth wheel, the grinding rate improvement of the blade abrasive cloth wheel relative to the louver abrasive cloth wheel is between 42% and 48%.

[0025] In this embodiment, in the comparison between the fan-shaped abrasive cloth blades 2 in this blade abrasive cloth wheel and the rectangular abrasive cloth blades of the louver abrasive cloth wheel, the utilization rate of the abrasive cloth blades of this blade abrasive cloth wheel is 30% higher than that of the louver abrasive cloth wheel.

[0026] In this embodiment, in the statistical comparison between the blade abrasive cloth wheel and the louver abrasive cloth wheel, the extended service time of the blade abrasive cloth wheel compared with the louver abrasive cloth wheel is between 33% and 37%.

[0027] In this embodiment, the outer side of the mounting ring surface 5 is inclined downward, and the lowest height of the bottom surface of the mounting ring surface 5 is higher than the bottom surface height of the hole ring 3.

[0028] As an implementable manner, the mounting ring surface 5 is horizontally arranged.
