Description

technical field [0001] The invention relates to a freely configurable universal electric and magnetic composite field laser cladding auxiliary device and method. Background technique [0002] Laser cladding technology is to place the selected cladding layer material on the surface of the substrate by adding materials such as synchronous powder feeding method or preset powder method. After laser irradiation, the light energy absorbed by the material is converted into heat energy, so that the cladding layer The material is melted, a molten pool is formed on the surface of the workpiece, and rapidly cooled and solidified to form a surface coating that is metallurgically bonded to the base material, thereby significantly improving the surface properties of the base. [0003] However, laser cladding is a process of rapid heating and rapid cooling and solidification. The difference in thermophysical properties between the cladding material and the base material leads to a large te...

Problems solved by technology

[0004] However, the existing electric and magnetic laser cladding auxiliary devices often have a single function, poor adjustability, can only generate a specific electric and magnetic composite field, or can only generate a single electric field / magnetic field, and have poor versatility and no clamping device. Or only specific cladding parts can be simply fixed, which greatly increases the cost and time of experiment and production, and affects the progress of experiment and production

[0005] The Chinese invention patent with the patent number CN 104195541 A discloses a method and device for electric-magnetic compound field synergistic laser cladding. The generating device is too simple, it can only generate a specific electric-magnetic compound field, and the generated electric-magnetic compound field has poor adjustability, there is no clamping device, and the parts cannot be fixed, and there is no lifting and moving device, and the parts cannot be adjusted. The location of the electric-magnetic compound field

[0006] The Chinese invention patent with the patent number of CN 106567072 A discloses an electric-magnetic compound field cooperative laser cladding device supplied by a permanent magnet. The device uses a permanent magnet to provide a magnetic field, which can adjust the direction and size of the magnetic field, and the substrate can be moved. And multi-angle transformation, but because the device uses permanent magnets for magnetization, the size of the magnetic field cannot be adjusted accurately, and the type of magnetic field generated is single. Simple fixation, no clamping device, can not realize the fixation of various parts

[0007] The Chinese invention patent with the patent number CN 105714284 A discloses a method and device for ultrasonic vibration-electromagnetic stirring composite energy field assisted laser cladding. The device uses electromagnets to provide magnetic fields and is controlled by a single-chip microcomputer. The magnetic field can be adjusted more accurately , but the electromagnet uses two rectangular parallelepiped iron cores, the iron cores are separated from each other, the magnetic field lines cannot complement each other, resulting in a loss of magnetic field strength, and the fixing method of the device parts is screwed at the bottom of the parts, and the cladding needs to be fixed before cladding Parts undergo additional handling, adding time and cost
