Description

Technical Field

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

[0002] The abrasive cloth wheel plays an important role in industrial production and is widely used in the processing of industrial products, mainly for functions such as grinding and polishing. Whether it is large-scale products like automobiles, ships, and aviation equipment, or small items like jade, shoe heels, and the production of stainless steel products, a large number of abrasive cloth wheels are required. The abrasive cloth wheel belongs to the category of industrial consumables and is also a necessity in industrial production.

[0003] Existing abrasive cloth wheels are all flat abrasive cloth wheels, usually composed of a group of gauze sheets arranged in an orderly manner on a tray. The tray is mostly made of plastic or grid fiberglass. There is an installation hole in the middle of the tray. During use, it is fixed to a special tool or angle grinder through the installation hole for mechanical or manual grinding, and the rotation of the machine drives the abrasive cloth wheel to rotate at high speed. Since the grinding sand surface of the abrasive cloth wheel is flat, it is usually suitable for grinding and polishing flat surfaces and regular-shaped flat surfaces. However, during the grinding and polishing process, the contact area with the grinding material is not large, the utilization rate of the abrasive tips on the entire gauze sheet is relatively low, and the irregular shapes of the edges and corners of the material cannot be effectively ground, thus affecting the grinding efficiency. Summary of the Invention

[0004] In order to solve the problem that most existing gauze sheets are flat, resulting in a small contact area with the grinding material during grinding and polishing, a relatively low utilization rate of the abrasive tips on the entire gauze sheet, and the inability to effectively grind the irregular shapes of the edges and corners of the material, thereby affecting the grinding efficiency, the utility model proposes an abrasive cloth wheel. By setting rectangular abrasive cloth blades, three surfaces of the abrasive cloth wheel can be used to grind the workpiece, solving the problem that the conventional abrasive cloth wheel can only grind flat workpieces.

[0005] To achieve the above object, the technical solution of the utility model is: an abrasive cloth wheel, including a tray and abrasive cloth blades. The tray is sequentially provided with a hole ring, an annular fixing surface, and an installation ring surface from the inside to the outside. The installation ring surface is located on the front of the tray. Each abrasive cloth blade is rectangular and is inclined on the installation ring surface. One side of the abrasive cloth blade is located at the connection of the annular fixing surface and the installation ring surface. The abrasive cloth blade extends out of the installation ring surface, fits the outer periphery of the tray, and is fixed on the back of the tray. The abrasive cloth blades are arranged in a fan shape on the tray, and one corner of the abrasive cloth blade forms an annular protrusion on the back of the tray.

[0006] Further, the abrasive cloth blades partially overlap, forming a front grinding portion on the front side of the tray, a side grinding portion on the outer periphery of the tray, and a back grinding portion on the back side of the tray. The grinding portions on the front, side, and back enable the three surfaces of this abrasive cloth wheel to grind the workpiece, expanding the scope of use of the abrasive cloth wheel. The annular protrusion is part of the back grinding portion and is the lowest height position of the back grinding portion. When using the back grinding portion of the grinding wheel, the annular protrusion is the first part to contact the workpiece, making the back grinding portion more reasonably utilized during the process of grinding the workpiece.

[0007] Further, the tray is a disk body made of fiberglass.

[0008] Further, the annular fixing surface is an arc surface, with the inner side lower and the outer side higher.

[0009] Further, the lowest height of the grinding portion on the back is higher than the bottom surface height of the hole ring, preventing the abrasive cloth wheel from interfering with the power machine during the grinding process.

[0010] Through the above technical solutions, the beneficial effects of the present utility model are as follows:

[0011] 1. In the present utility model, on one side of the abrasive cloth blade, at the connection between the annular fixing surface and the mounting ring surface, the other side of the abrasive cloth blade extends out of the mounting ring surface and adheres to the annular protrusion and is then fixed on the back of the tray. Multiple abrasive cloth blades are arranged in a fan shape on the mounting ring surface, and each abrasive cloth blade partially overlaps to form the front, side, and back grinding portions, enabling the three surfaces of this abrasive cloth wheel to grind the workpiece, solving the problem that the conventional abrasive cloth wheel can only grind flat workpieces. When using the back grinding portion of the grinding wheel, the annular protrusion is the first part to contact the workpiece, making the back grinding portion more reasonably utilized during the process of grinding the workpiece.

[0012] 2. The side grinding portion of the abrasive cloth wheel of the present utility model can grind right-angle welds, solving the problem that only consolidated grinding wheels could grind right-angle welds in the past. At the same time, the abrasive cloth wheel of the present utility model can effectively grind and polish the groove-shaped surface of the workpiece.

[0013] 3. The exposed cloth base surface of the present utility model is bonded by an adhesive, enabling the abrasive cloth wheel to maintain good elasticity during the grinding process, reducing the vibration caused by the unevenness of the workpiece being ground, reducing the labor intensity of the operator, and since the grinding surface is a curved surface, there are gaps on both sides of the contact surface during grinding for heat dissipation, achieving a certain cooling effect and not easily burning the surface of the workpiece.

[0021] The present utility model will be further described below in conjunction with the drawings and specific embodiments:

[0022] As Figures 1 to 6 shown, this embodiment provides a sanding wheel, including a tray 1 and sanding cloth blades 2. The tray 1 is successively provided with a hole ring 3, an annular fixing surface 4 and a mounting ring surface from inside to outside. The mounting ring surface 5 is located on the front of the tray 1. Each sanding cloth blade 2 is rectangular and is inclined on the mounting ring surface 5. One side of the sanding cloth blade 2 is located at the connection of the annular fixing surface 4 and the mounting ring surface 5. The sanding cloth blade 2 extends out of the mounting ring surface 5, fits the outer periphery 6 of the tray 1 and is fixed on the back of the tray 1. The sanding cloth blades 2 are arranged in a fan shape on the tray 1. One corner of the sanding cloth blade 2 forms an annular protrusion 7 on the back of the tray 1. The sanding cloth blades 2 partially overlap, forming a front grinding part on the front of the tray 1, a side grinding part on the outer periphery 6 of the tray 1, and a back grinding part on the back of the tray 1. The annular fixing surface 4 is an arc surface, with the inner side of the arc surface being low and the outer side being high. The lowest height of the grinding part on the back is higher than the bottom surface height of the hole ring 3. The noise of this sanding wheel is reduced by 60% and the dust is reduced by 55% in the grinding test comparison with the vitrified grinding wheel.

[0023] In this embodiment, the annular protrusion 7 is a part of the back grinding part. As Figure 2 shown, one corner of multiple sanding cloth blades 2 forms an annular protrusion 7 on the back of the tray 1. When the back grinding part is in use, the part that first contacts the workpiece to be polished can reduce the loss of the back grinding part and improve the service life of the back grinding part. The height of the other corner of the sanding cloth blade 2 is higher than the annular protrusion 7 and is fixed on the back of the tray 1.

[0024] In this embodiment, the tray 1 is a tray body made of fiberglass mesh cloth.

[0025] In this embodiment, the side grinding surface is a curved surface. There are gaps on both sides of the contact surface during grinding for heat dissipation, which has a certain cooling effect, can reduce the problem that the abrasive cloth blades 2 are broken during the use of the abrasive cloth wheel. At the same time, the abrasive cloth blades 2 are adhered to the mounting ring surface 5 and the back surface of the tray 1 through an adhesive, can maintain good elasticity, and reduce the shaking caused by the unevenness of the workpiece being polished.

[0026] When encountering right-angle welds, the bottom of grooves and both sides of grooves that cannot be polished by an abrasive cloth wheel that can only be polished on one side, the utility model abrasive cloth wheel described in this patent can be used for convenient and effective polishing.

[0027] The above-described embodiments are only the preferred embodiments of the present utility model, and do not limit the scope of implementation of the present utility model. Therefore, any equivalent changes or modifications made according to the structure, features, and principles described in the scope of the present utility model patent should be included within the scope of the patent application of the present utility model.
