Description

Technical Field

[0001] The utility model belongs to the field of steel material processing and polishing devices, in particular to a steel material processing and polishing device. Background Art

[0002] Polishing devices are equipment used to polish and grind the surface of materials. They are widely used in the manufacturing industry to improve the surface quality and appearance of products. Common polishing tools include grinding wheels, sanding belts, sanding rollers, etc. Different polishing tools are selected according to different materials. After the steel plate is processed, it needs to be polished with a polishing device to improve the appearance and surface quality of the steel plate material, provide a smooth and bright surface, and remove the defects and roughness on the surface of the steel plate.

[0003] According to the Chinese patent application number: 202022629744.3, a device for polishing a curved surface of a steel material is disclosed, which relates to the technical field of steel surface polishing, including a main device, a lifting device, a conveying device, a polishing device and a cleaning device. The main device includes a frame and an operating table, and the upper surface of the frame is connected to the lower surface of the operating table. The lifting device includes a base and a connecting rod. The lower surfaces of the bases are welded to the upper surface of the frame. The conveying device includes a fixed block, and the inner surfaces of the fixed blocks are respectively connected to the outer surfaces of the connecting rods. The polishing device includes a chassis, and the lower surface of the chassis is connected to the upper surface of the operating table. The cleaning device includes a pillar, and the lower surface of the pillar is connected to the upper surface of the operating table. The polishing wheel is made of high-strength fiber material, which can effectively perform preliminary polishing on the steel. The polishing wheel can be disassembled and replaced. The surface of the fine polishing roller is wrapped with a layer of oily foam, which can further polish the steel.
