Description

Technical Field

[0001] This utility model relates to the field of rust removal devices, specifically to a rust removal device for metal processing. Background Technology

[0002] The steel pipe rust removal machine is a combined rust removal machine for cleaning the inner and outer walls of steel pipes. It uses shot blasting to clean the rusted areas of the steel pipe, removing the oxide scale from the surface. A Chinese patent discloses a rust removal device for metal processing (authorization announcement number CN221696450 U). This patented technology, through its grinding cylinder and grinding disc, combined with a cover plate and its transparent design, prevents rust debris from splashing into the grinding cylinder during grinding, effectively limiting the debris to a specified range and facilitating subsequent collection. Simultaneously, a receiving frame and a second handle effectively catch the debris splashing into the grinding cylinder. The second handle allows for quick removal of the receiving frame from the grinding cylinder during subsequent cleaning, making the cleaning process more convenient and efficient. However, this design cannot perform rust removal on the inner surface of cylindrical rusted metal. Therefore, those skilled in the art have provided a rust removal device for metal processing to solve the problems mentioned in the background art. Utility Model Content
