Description

Technical Field

[0001] The utility model relates to the technical field of metal coil grinding, especially to the technical field of grinding devices. Background Art

[0002] Metal coils, as coiled materials with metal as the base material, must undergo processes such as cold rolling and cutting in their processing flow. However, these processing processes are often accompanied by the generation of a large number of burrs. The burrs are specifically manifested as tiny debris remaining on the metal surface and extremely fine metal particles adhering to it. The quantity of burrs is directly related to the quality rating of the metal coil. The more burrs there are, the lower the quality standard. To ensure that the subsequent processing and use of the metal coil are not affected, measures must be taken to remove these burrs. Common cleaning methods include using a file to carefully file the parts with burrs to eliminate the burrs; or using a whetstone and through grinding technology to also achieve the purpose of removing burrs and restoring the smoothness of the metal surface.

[0003] For example, the Chinese utility model patent with the publication number CN209350091U proposes a high-strength grinding roll that is convenient for heat dissipation, including a rotating shaft. A grinding body with multiple spiral protrusions is detachably connected to the rotating shaft. A chip discharge groove is formed between adjacent two spiral protrusions. The grinding body includes a connecting sleeve detachably connected to the rotating shaft. A grinding sleeve with left spiral protrusions and right spiral protrusions is sleeved outside the connecting sleeve. The number of right spiral protrusions is the same as that of the left spiral protrusions and the left spiral protrusions intersect with the right spiral protrusions. A heat dissipation area is formed between the connecting sleeve and the grinding sleeve, and reinforcing plates are fixed between the connecting sleeve and the grinding sleeve. Diamond abrasives are embedded on the surfaces of the left and right spiral protrusions.

[0004] The above structure grinds the surface of the metal coil through the grinding roll to achieve the purpose of removing burrs and restoring the smoothness of the metal surface. However, the service life of the grinding roll is limited and needs to be replaced frequently. When replacing the grinding roll of the above structure, the entire grinding roll needs to be replaced, resulting in high replacement costs. Moreover, the installation and disassembly during replacement are relatively troublesome, with high labor intensity and low efficiency. Summary of the Invention
