Laser repair method for damaged parts

Abstract

The invention discloses a laser repair method for damaged parts. According to the laser repair method, a damaged roller is repaired through a laser repair device. The laser repair device comprises a roller clamping device, a frame base, a moving mechanism and a laser, wherein the moving mechanism is arranged on the frame base; the laser is arranged on the moving mechanism; a fixed upright post anda movable upright post are arranged at the left end and the right end of the frame base respectively; the roller is placed between the fixed upright post and the movable upright post; a fixed seat isconnected to the fixed upright post through a fixed connection block; and a rotatable chuck is arranged in the center of the fixed seat. According to the laser repair method disclosed by the invention, laser repair is carried out on the roller to be repaired through the laser repair device, and the laser repair device is reasonable in design, convenient to operate and reliable in positioning, andcan effectively improve the repair efficiency of roller laser repair.

Description

technical field [0001] The invention relates to a repair method, in particular to a laser repair method for damaged components. Background technique [0002] The roll is the main working part and tool for continuous plastic deformation of the metal on the rolling mill, and is an important consumable part that determines the efficiency of the rolling mill and the quality of the rolled material. The roll is an important part of the rolling mill, which uses the pressure generated by a pair or a group of rolls to roll and roll the steel. During the rolling process, due to the great working stress of the roll, and the impact of the roll on the roll, such as inclusions and edge cracks, it is easy to cause damage to the roll, such as scratches, cracks, sticking, peeling, etc. on the roll surface. Serious wear on the working surface of the roll will seriously affect the service life and machining accuracy of the roll. The damaged roll can be repaired by laser cladding. [0003] La...
