Roll surfacing repair device and repair method

Abstract

The invention discloses a roll surfacing repair device and a repair method. The roll surfacing repair device comprises two bearing bases and two groups of surfacing assemblies, wherein each of the two groups of surfacing assemblies comprises a transverse guide rail, a longitudinal guide rail and a welding machine; first bearing plates are separately arranged on the transverse guide rails; the longitudinal guide rails are separately arranged on the first bearing plates; second bearing plates are arranged on the longitudinal guide rails; the welding machines are arranged on the second bearing plates; a thermal insulation cover is arranged between the two bearing bases; and roll repair is carried out by detecting before surfacing, pre-heating before welding, welding, heat treatment and processing. In this way, the roll surfacing repair device and the repair method adopt the surfacing assemblies to replace part of manual operation, so that risks are reduced; and moreover, the thermal insulation cover is especially adopted, so that the work of a welding gun is not affected, loss of heat can be reduced, energy consumption is reduced, the technical temperature of roll surfacing is ensured, and the surfacing quality is improved.

Description

technical field [0001] The invention relates to the field of roll repair, in particular to a roll surfacing repair device and repair method. Background technique [0002] The roll will have normal wear and abnormal damage during use, which will reduce the size of the roll and present irregular pits on the surface. If the size is reduced beyond the limit or the pit is too large, it will not work normally, and the roll needs to be replaced or repair. [0003] The replacement cost of the roll is relatively high, so most of them choose to repair it. The traditional roll repair method is to accumulate welding materials on the surface of the roll by manual surfacing welding, and then process it into the original size. Because the surfacing temperature of the roll is high, and repeated heating is required during surfacing, the energy consumption is large. , high labor intensity, harsh high temperature environment, easy to burn, low work efficiency, poor welding quality, need to b...
