Technical Field

[0001] The utility model relates to the technical field of grinding, in particular to a surface grinding device. Background Art

[0002] Butterfly valves are widely used in industry because of their simple structure, small size, light weight, low material consumption, small installation size, small driving torque, easy and quick operation, and good flow regulation function and closing and sealing characteristics. Its main functional component is the valve disc. Since the movement of the butterfly valve disc is wiping, the surface of the cast valve disc has a lot of burrs and oxide scales, which will cause iron filings to flow into the medium, scratch the sealing ring, and cause component damage.

[0003] During the casting process of valve discs, due to the influence of various factors such as environment, materials and process, an oxide coating is formed on the surface of the casting. This oxide coating is mainly composed of metal oxides generated by the reaction of metal with oxygen and water vapor in the atmosphere. Casting oxide scale is an important issue in many industries, and the presence of casting oxide scale will have an adverse effect on the quality of the casting. First, the oxide scale will make the surface of the casting rough, resulting in a decrease in surface finish, thereby reducing the aesthetics of the casting. Secondly, the oxide layer may destroy the complete contact between the casting and the mold, causing problems such as poor mold pouring and defects, and ultimately leading to defects such as inclusions or pores inside the casting; in addition, the oxide layer may also cause abnormal precipitation of metal elements or disordered crystal structure, resulting in a decrease in material performance.

[0004] Therefore, valve discs need to go through a grinding stage, but the traditional method of deburring and descaling is mostly manual grinding with a grinding wheel, which is inefficient and difficult to guarantee quality. Utility Model Content
