Description

Technical Field

[0001] The utility model relates to the technical field of rust removal devices, in particular to a rust removal device for the outer wall of a welded pipe. Background Art

[0002] Welded steel pipe, also known as welded pipe, is a steel pipe made by welding steel plates or strips after curling and forming. It is generally fixed in length of 6 meters. The production process of welded steel pipe is simple, the production efficiency is high, and there are many varieties and specifications. During the processing of welded pipes, if anti-rust treatment is not carried out in time, rust will form on the outer wall of the welded pipe during storage, which will affect the subsequent use. When using, the rust on the outer wall of the welded pipe needs to be removed.

[0003] The rust removal device currently used, as shown in the application document with the prior art publication number CN217728293U, includes: a drive box, a three-jaw chuck and a moving mechanism, wherein a support frame is fixed to the transmission end of the moving mechanism, a rust removal mechanism for grinding and rust removal is installed on one side of the support frame, and a rust prevention mechanism for applying rust prevention oil is installed on the other side of the support frame; the grinding plate on the first rotating roller contacts the welding pipe, and grinds and removes rust on the rotating welding pipe. When grinding and removing rust on the welding pipe, according to the grinding requirements, the first rotating roller is driven to rotate by the first driving module, and the grinding plate with the corresponding roughness is rotated to face upward to grind and remove rust on the welding pipe. The grinding and rust removal can be carried out by a grinding plate with a higher roughness, and then the grinding plate with a lower roughness is switched for polishing. It can be switched flexibly and does not require manual shutdown and replacement by personnel, effectively improving the rust removal efficiency.
