Abstract

The invention discloses an electromagnetic assisted laser synchronous cladding device and method for remanufacturing metal parts. The electromagnetic assisted laser synchronous cladding device comprises a six-degree-of-freedom actuator, a laser, an electromagnetic induction heater, a powder spraying device and a workbench, wherein the working table is used for containing a workpiece to be machined, and the powder spraying device is used for spraying metal powder to the surface of the workpiece to be machined; the laser is installed at the tail end of the six-degree-of-freedom actuator, and thelaser is used for generating high-energy lasers for achieving cladding of the metal powder on the surface of the workpiece arranged on the workbench; the electromagnetic induction heater comprises aninduction coil and an induction power supply for supplying power to the induction coil, and the induction coil is made of a hollow metal tube; and cooling water is fed into the hollow metal tube forcooling, and the induction coil is arranged below the laser device and used for carrying out auxiliary cladding on the metal powder on the surface of the workpiece to generate an eddy current. According to the electromagnetic assisted laser synchronous cladding device, the structure is simple, the cladding speed is high, the powder utilization rate is high, and the applicable cladding material range is wide.

Description

technical field [0001] The invention belongs to the technical field of remanufacturing of metal parts, relates to a device for remanufacturing and repairing parts using lasers, and in particular to an electromagnetic-assisted laser synchronous cladding device and method for remanufacturing of metal parts. Background technique [0002] The remanufacturing methods of metal parts mainly include arc surfacing repair technology, thermal spray repair technology, brush plating repair technology, laser cladding repair technology, etc. When the arc surfacing repair technology is used, when the melting point and thermal conductivity of the two metals differ greatly, the welding heat-affected zone is wide, the weld quality is poor, and large welding stress and deformation are generated; when the thermal spraying method is used, the coating and the substrate are difficult. Form a metallurgical bond, easy to peel off during use. [0003] Laser cladding technology is a process that uses ...
