AI Technical Summary
Existing roll local dent repair devices cannot achieve rapid processing after welding, resulting in low processing efficiency.
A device for repairing local dents in a rolling mill was designed. The polishing and grinding mechanism is set separately from the welding and repair components. The sliding block can move freely by the output of the moving screw, so as to achieve simultaneous polishing and grinding and welding repair.
This improved the processing efficiency of repairing localized dents in rolls and achieved simultaneous repair of products.
