Description

Technical Field

[0001] The utility model relates to the technical field of forging polishing, and more specifically to a steel forging finishing polishing device. Background Art

[0002] Steel castings refer to parts made of cast steel, which have similar properties to cast iron, but are stronger than cast iron. Steel castings are prone to defects such as pores and inaccurate angle positioning during the casting process, and the casing may break during long-term use. One of the advantages of steel castings is the flexibility of design. Designers have the greatest freedom to design the shape and size of castings, especially parts with complex shapes and hollow sections. Steel castings can be manufactured using the unique process of core assembly.

[0003] At present, after the production of steel castings is completed, there are usually burrs on their surfaces, so a polishing device is needed to smooth their surfaces, and the polishing device can also improve the glossiness of the casting surface. Traditional polishing devices can generally only polish castings with relatively flat surfaces. However, for castings with irregular surfaces such as engine casings, traditional polishing devices are difficult to achieve rapid polishing, and it is not convenient to fully polish the inner wall of the engine casing. There are prone to polishing dead corners, which affects the polishing quality of steel castings. In view of this, we propose a steel forging finishing polishing device. Utility Model Content
