Description

Technical Field

[0001] This utility model relates to the field of louvered sanding disc technology, specifically a detachable split-type louvered sanding disc. Background Technology

[0002] Louvered abrasive discs, also known as high-strength elastic abrasive discs, are made of plastic or fiber mesh covers bonded with abrasive cloth blades. A simplified version of the traditional louvered abrasive disc, they are primarily used for grinding and polishing in industrial production and are considered industrial consumables. The base material of louvered abrasive discs includes mesh, nylon, plastic, and steel paper, with varying numbers of blades evenly distributed in a fan shape. Grit sizes range from 36# to 400#, with 60# and 80# being the most common. With an outer diameter of 4"-7", they are mounted on angle grinders or handheld electric grinders for grinding and repairing weld seams and burrs on positive edges. They are interchangeable with cymbal-shaped grinding wheels and offer advantages such as good elasticity, high efficiency, good heat dissipation, and low noise. They can replace resin cymbal-shaped grinding wheels, possessing strong elasticity, high tensile and bending strength, good self-sharpening properties, high grinding rate, and low noise. Suitable for grinding weld seams inside boxes and burrs on stamped parts, they are mainly used for grinding and polishing various stainless steel and carbon steel structural components.

[0003] For existing detachable split-type louvered grinding discs, refer to Chinese Utility Model Patent Application No. CN201520995809.2, which discloses a louvered grinding wheel for polishing. "It includes a grinding wheel body, which comprises blades, a cymbal-shaped base, and a mounting hole. The cymbal-shaped base includes a circular recess, a cap, and a positioning ring. The blades are arranged evenly in a fan shape on the edge of the cymbal-shaped base, and the bonding angle between the blades and the plane of the cymbal-shaped base is 10°~30°. The edge of the cap has a positioning ring, and the grinding wheel body has a grinding wheel hole in the center. This utility model also has the advantages of high grinding efficiency, good heat dissipation, and resistance to clogging."
