Description

Technical Field

[0001] The present invention relates to the technical field related to laser cladding equipment, and specifically provides a metal material laser cladding equipment. Background Art

[0002] Laser cladding technology is a new surface modification technology that emerged in the 1970s with the development of high-power lasers. It refers to the rapid heating and melting of alloy powder or ceramic powder and the substrate surface under the action of a laser beam. After the beam is removed, it self-cools to form a surface coating with an extremely low dilution rate and metallurgically bonded to the substrate material, thereby significantly improving the wear resistance, corrosion resistance, heat resistance, oxidation resistance and electrical properties of the substrate surface. Laser cladding technology can greatly improve the hardness, wear resistance and corrosion resistance of the part surface. At the same time, it can also be recycled and remanufactured, saving the cost of parts and extending their service life. Laser cladding is widely used in aviation, military, petroleum, chemical industry, medical and other fields.

[0003] When the laser spray gun assembly sprays the cladding material, a large amount of fire will be generated. Workers in this environment will involuntarily look at the workpiece, causing eye discomfort. If the nozzle position is set too high, the powder will diverge greatly and the powder utilization rate will be low. If the nozzle position is too low, the nozzle will easily stick to the powder during cladding. Therefore, we need to improve the above problems. Summary of the invention

The backlight shell can be adjusted according to different workpieces so that the backlight shell can rotate in conjunction with the laser jet assembly. The extended shell inside the backlight shell can not only increase the shielding area, but also gather the area where the laser cladding is performed on the side of the metal material, so that the material sprayed by the laser jet assembly can be centered around the spraying, and the cladding material will not be wasted. In order to avoid the problem of powder sticking caused by the use position of the laser jet assembly, the cooling air pipe arranged inside the deflector plate can not only gather the sprayed material, but also meet the cooling of the laser jet assembly in the later stage, avoiding the occurrence of spraying wrinkles due to the excessive temperature of the molten pool. The cooling air pipe can be connected to an external temperature-controlled delivery pump to help cool the laser jet assembly. The cold air flow then contacts the deflector plate, allowing the gas to evenly flow back to the outside of the laser jet assembly, so that the laser jet assembly can continue to spray a relatively stable coating in the later stage, thereby increasing the stability of the cavity metal material.
