An ultrasonic vibration composite wire feeding device for laser wire feeding cladding forming comprises a platform moving mechanism, a laser working mechanism, a wire feeding mechanism, an ultrasonic vibration mechanism and a platform control center. The platform moving mechanism is a movable platform; the laser working mechanism comprises a laser cladding head; the laser cladding head emits laser to carry out cladding processing on a workpiece; the wire feeding mechanism comprises a wire guide pipe and a wire feeding nozzle, and a wire enters the nozzle through the wire guide pipe and then is guided out through the wire feeding nozzle; the ultrasonic vibration mechanism is arranged in the wire feeding nozzle and located on the two sides of the wire, so that the wire generates high-frequency vibration and is coupled to a molten pool generated by the laser beam. The invention further provides a method of the ultrasonic vibration composite wire feeding device for laser wire feeding cladding forming. The ultrasonic vibration and the wire feeding are combined and applied to the laser cladding forming process, the surface forming effect of a cladding layer is improved through the auxiliary effect of the ultrasonic vibration, the process quality is improved, and the manufacturing cost is reduced.
Description
technical field [0001] The invention relates to the fields of laser wire feeding cladding, laser surface modification and laser surface repair, in particular to an ultrasonic vibration composite wire feeding device and method for laser wire feeding cladding forming. Background technique [0002] Laser cladding technology is an advanced thermal processing manufacturing technology.
