Description

Technical Field

[0001] The utility model relates to the technical field of powder metallurgy product processing, and particularly relates to a polishing device for powder metallurgy product processing. Background Technique

[0002] The metal product industry includes the manufacture of structural metal products, metal tools, containers and metal packaging containers, the manufacture of stainless steel and similar daily-use metal products, etc. Metal products are used more and more widely in various fields of industry, agriculture and people's lives. Especially powder metallurgy products are usually used to process metal fittings, and during the processing of the fittings, it is usually necessary to polish the outer surface thereof to ensure the smoothness of the outer surface of the metal product.

[0003] In the prior art, in the patent document with the publication number of CN220902894U, a surface polishing device for metal product production and processing is proposed, which relates to the technical field of metal product polishing.

The mutual cooperation of the clamping rod, the L-shaped rod and the limiting rod disclosed in the application can ensure that after the angle of the articulated frame and the position of the movable block and the polishing disc are adjusted, the articulated frame and the movable block are simultaneously limited, effectively ensuring that after the metal workpiece is limited, it will not be affected by external forces and cause the problem of deviation of the metal workpiece.
