Description

Technical Field

[0001] The utility model relates to the technical field of polishing machines, in particular to a casting processing polishing machine. Background Art

[0002] During the casting process, some defects such as burrs and pores will appear on the surface of the casting, which will affect the appearance and mechanical properties of the casting. Polishing can effectively remove these defects and make the surface of the casting smoother. The quality of the casting surface has a great influence on the mechanical properties and service life of the casting. Polishing can improve the surface finish and flatness of the casting, reduce surface roughness and friction coefficient, thereby improving the surface quality of the casting. During the casting process, some bumps or depressions may appear on the surface of the casting. These irregular geometric shapes will affect the dimensional accuracy of the casting. Polishing can make the surface of the casting smoother, thereby improving the dimensional accuracy. The roughness and defects on the surface of the casting will accelerate the corrosion and oxidation of the casting, thereby reducing the service life of the casting. Polishing can reduce defects and roughness on the surface of castings and enhance the corrosion resistance of castings. Polishing is a very important step in the casting processing process. It can improve the surface quality and dimensional accuracy of castings, extend the service life of castings, and ensure the mechanical properties and appearance quality of castings. Existing polishing machines such as drum grinding and polishing machines are placed in a drum, and the drum rotates to make the internal grinding parts polish the castings. However, this polishing machine needs to remove the cover from the drum when loading the casting. Removing the cover is both laborious and time-consuming. After loading, the cover needs to be covered and fixed. When unloading, there is a certain space between the drum and the guide plate below. The casting will fall directly on the guide plate, which is easy to cause damage to the appearance of the casting, which is not conducive to use; for example, "Utility Model CN218285057U A polishing machine for surface treatment of metal castings. The utility model has a cover that is not separated from the drum during use, which makes it convenient to open the cover to discharge materials. At the same time, when the drum is discharging materials, the cover can guide the casting to prevent the casting from falling on the guide plate and causing damage to the appearance of the casting.
