Description

Technical Field

[0001] The utility model relates to a plane emery cloth wheel which is easy to use and belongs to the technical field of emery cloth wheels. Background Art

[0002] Flat emery wheels play an important role in industrial production and are widely used in the processing of industrial products. They mainly play the role of grinding and polishing. They are used in large-scale applications such as automobile, ship, and aviation manufacturing, as well as small-scale applications such as jade grinding, heel grinding in shoe factories, stainless steel product manufacturing, and furniture manufacturing. Flat emery wheels belong to the category of industrial consumables and are also necessities in industrial production.

[0003] Traditional flat abrasive wheels (such as Figure 5 As shown in the figure, when the emery cloth piece 12 is attached to the base 11, the number of emery cloth pieces 12 overlapping near the axial hole 110 will be greater than the number of emery cloth pieces 12 away from the axial hole 110, resulting in the thickness of the area near the axial hole 110 being greater than the thickness of the area away from the axial hole 110. In other words, looking at the grinding surface of the plane emery cloth wheel as a whole, the thickness near the central area is greater than the thickness of the edge area. When using a plane emery cloth wheel for grinding, the edge area of ​​the plane emery cloth wheel is generally used for grinding. If the thickness near the central area is greater than the thickness of the edge area, two situations will occur. One is that during parallel grinding, the edge area of ​​the plane emery cloth wheel cannot contact the surface of the product, affecting the grinding quality; the other is that the user needs to adjust the angle of the handheld angle grinder so that the edge area of ​​the plane emery cloth wheel can contact the surface of the product, which is inconvenient to use.

[0004] Therefore, how to provide a flat emery cloth wheel that is easy to use is the research purpose of the utility model. Utility Model Content

[0005] In view of the deficiencies in the above-mentioned technology, the utility model provides an easy-to-use flat emery wheel, which is composed of an emery cloth sheet with a notched structure, and the overlapping area of ​​the emery cloth sheet close to the shaft hole is overlapped with the notched structure, thereby reducing the thickness of the area, so that the thickness of the edge area of ​​the flat emery cloth wheel is equal to or greater than the thickness of the central area, thereby making the edge area of ​​the flat emery cloth wheel able to contact the surface of the product without adjusting the angle of the angle grinder, which is more convenient for grinding.

[0011] Furthermore, one side of each group of the abrasive cloth sheets away from the base or the bottom cover is covered with an abrasive particle coating.

[0012] The beneficial effect of the utility model is that a plane grinding wheel is formed by forming a grinding cloth sheet with a notched structure, and the overlapping area of ​​the grinding cloth sheet close to the shaft hole is overlapped with the notched structure, thereby reducing the thickness of the area, so that the thickness of the edge area of ​​the plane grinding wheel is equal to or greater than the thickness of the central area, so that the edge area of ​​the plane grinding wheel can contact the surface of the product without adjusting the angle of the angle grinder, which is more convenient for grinding.
