The invention discloses a laser cladding processing method with a multi-directional light beam synchronization effect, and belongs to the technical field of laser cladding. The laser cladding processing method comprises the following steps: 1) according to a portion, needing laser cladding processing, of a processed part, arranging a plurality of collimating heads on one side of a workpiece, and configuring a corresponding powder feeding nozzle for each collimating head; 2) adjusting the angle and the focal length of each collimating head, and adjusting the angle and the position of each powder feeding nozzle; and 3) performing trial processing by using a sample workpiece, spraying powder by the powder feeding nozzles, emitting laser by the collimating heads for cladding processing, and detecting the size of the sample workpiece. According to the laser cladding processing method, the positions, the angles and the powers of the collimating heads are adjusted by utilizing the multiple collimating heads to correspond to different processing positions, the multiple powder feeding nozzles are connected to the same powder feeder, and adjustment is performed by utilizing an independent pressure regulator, so that simultaneous processing of different positions of a special-shaped workpiece is adapted, and the problem that a thin workpiece is locally heated and deformed is solved.
Description
technical field [0001] The invention belongs to the technical field of laser cladding, and in particular relates to a laser cladding processing method in which multi-directional beams act synchronously. Background technique [0002] Laser cladding, also known as laser cladding or laser cladding, is a new surface modification technology. It forms a metallurgically bonded cladding layer on the surface of the base by adding cladding materials on the surface of the substrate and using a high-energy-density laser beam to fuse it together with the thin layer on the surface of the substrate. [0003] Chinese patent (CN202110087598.2) discloses a high-speed laser cladding processing method for rods and columns used in hydraulic supports, including the following steps: blanking, and retaining a certain processing allowance on the basis of the external dimensions of the finished rods and columns; Quenching and tempering, set the heat treatment quenching and tempering parameters accor...
