Description

Technical Field

[0001] The utility model relates to the technical field of polishing, in particular to a surface polishing device for metal smelting and rolling products. Background Art

[0002] Metal smelting rolled products refer to the finished products obtained after the refining and rolling processing of metals and their alloys. For example, ferrous metals mainly refer to iron and its alloys, such as steel, pig iron, iron alloys, cast iron, etc. Ferrous metal smelting usually refers to the smelting of iron ore into pig iron, or the smelting of pig iron into steel billets. Rolling processing is the process of rolling steel billets into steel plates or various steel sections, applying pressure to the metal to stretch it into a certain shape.

[0003] During the above processing, a polishing device is used. The existing polishing device does not have a dust collection function. When people use the polishing device, they cannot centrally process the dust, which easily causes dust to fly, causing harm to people's bodies and pollution to the surrounding environment. After searching, the authorization announcement number is CN 219170497 U (hereinafter referred to as: symmetry ratio file D1) utility model patent discloses a surface polishing device for ferrous metal smelting and rolling products. As an existing technology, although this device solves the problem of dust dispersion to a certain extent, it still has shortcomings during use: 1) When the workpiece is fixed, the surface of the workpiece can only be ground and polished by the polishing wheel that moves horizontally left and right, and the polishing range is limited. When part of the workpiece surface needs to be polished in the longitudinal direction, the position of the workpiece needs to be changed, which is cumbersome to operate and affects work efficiency; 2) The dust in the shell is sucked out by a hose, but the dust located at the bottom of the shell, that is, the dust located on the surface of the workpiece, is not obviously sucked out by the hose, and the dust collection capacity needs to be improved; for this reason, we design a surface polishing device for metal smelting and rolling products to solve the above technical problems.

At the same time, the device can start the first motor 15, and the first motor 15 drives the main gear 16 to rotate, thereby driving the sub-gear 14 to rotate, and then driving the base 13 to rotate, so that the workpiece itself can be driven to rotate. Combined with the lateral movement of the polishing wheel 30, the workpiece surface can be polished in all directions. The operation is simple and convenient, and the polishing effect is better, which greatly improves work efficiency.
