Description

Metal sheet grinds flat burnishing device Technical Field The application relates to the technical field of metal plate polishing, in particular to a metal plate polishing device. Background In the processing of sheet metal connecting pieces used for electric power towers, strict requirements are placed on structural strength and surface accuracy, and laser cutting is a mainstream blanking mode due to the advantages of high cutting accuracy, high efficiency, wide applicable materials and the like. However, in the laser cutting process, irregular burrs and slag are formed at the cut of the sheet material due to local high-temperature melting and cooling solidification, the burrs have high hardness, so that the appearance quality of the sheet metal is affected, the problems of loose fitting, reduced connection strength and the like are caused in the subsequent assembly, welding and other working procedures, and even operators are possibly scratched, and therefore, the cut sheet metal must be subjected to grinding and polishing treatment through special grinding and polishing equipment so as to remove the burrs, improve the surface smoothness and flatness, and ensure the subsequent processing quality and the use safety of products. In the prior art, the metal plate polishing mode mainly comprises manual polishing and automatic polishing, wherein the manual polishing relies on an operator to hold a polishing tool to finish operation, has the defects of low processing efficiency, unstable polishing quality and high labor intensity, is only suitable for processing small-batch and special-shape workpieces, and is widely used for automatically polishing flat plate type metal plate connecting pieces with large dosage and relatively regular shape in electric iron tower processing. The plane polishing and grinding machine is characterized in that a power system drives grinding rolls, abrasive belts and other grinding tools to rotate at a high speed, meanwhile, the metal plate is conveyed through a conveying belt, the grinding tools are in contact with the surface of the metal plate in the conveying process, burrs, oxide layers, scratches and other flaws on the surface of the metal plate are removed through the cutting action of abrasive particles, meanwhile, rough grinding and fine polishing procedures can be achieved through changing the grinding tools (such as wool polishing rolls), however, under the influence of the conveying belt, the grinding tools are only arranged above the conveying belt, only one side of the metal plate can be ground, after the one side of the metal plate is ground, the plate is turned over manually or through additional equipment, and then the other side of the metal plate is ground again, so that the overall grinding efficiency is low. In order to solve the above problems, a targeted improvement has been developed in the prior art. For example, the Chinese patent application with the application publication number of CN120244712A discloses a polishing device for surface treatment of a bearing bush plate, the device comprises a fixed base, a sealing cover, a double-polisher assembly and a matched rectifying and dust collection system, wherein a first polisher and a second polisher are arranged in the sealing cover, the two sides of the plate can be polished simultaneously through the cooperative driving of a lifting rod and a lifting ejector rod, the dust collection cover is matched with the dust collector and the double fans, polishing scraps and metal powder adhered to the surface of a polishing belt can be cleaned synchronously, and the polishing effect is guaranteed. Although the equipment is used for remarkably improving the polishing technology of the metal plates, a plurality of defects still exist to be solved when the electric iron tower connecting piece is polished, firstly, in order to avoid mutual interference of an upper polisher and a lower polisher and ensure smooth plate conveying, the scheme adopts the design of staggered arrangement of the upper polisher and the lower polisher, so that the overall polishing stroke of the equipment is remarkably increased, the polishing time of a single workpiece is prolonged, the single polishing efficiency is restrained from being improved, in addition, static electricity is generated due to high-speed friction between a grinding tool and the plates in the polishing process of the metal materials, fine metal scraps are easy to carry static electricity and are attached to the surfaces of the plates and the inner walls of assembly holes through static electricity adsorption force, and then, separate cleaning procedures are required to be additionally arranged, so that the processing cost is further increased, and the overall production efficiency is reduced. Disclosure of Invention In view of the above, the present application provides a metal plate polishing device for solving the problem that metal scraps are adsorbed in holes on the surf
