Problems solved by technology

[0003] When the existing laser cladding equipment transports the powder material, it cannot accurately transport the powder to the molten pool, which not only causes waste of alloy powder, but also has poor powder convergence, and many powders cannot directly enter the molten pool, resulting in laser cladding processing. Unstable quality

Abstract

The present invention provides a laser cladding and powder conveying device, comprising a powder bin, a powder conveying device and a nozzle; the output port of the powder bin communicates with the feed port of the powder conveying device, a hollow laser path is arranged inside the nozzle, the nozzle is provided with a plurality of through powder conveying pipes, the discharge port of the powder conveying device communicates with the powder conveying pipes, and the powder conveying device conveys powder from the powder bin to the powder conveying pipes; the laser cladding and powder conveyingdevice also comprises a powder distributing device and a gas source; the input end of the powder distributing device communicates with the discharge port of the powder conveying device, and the outputend of the powder distributing device communicates with the powder conveying pipes; and the gas source is connected with the nozzle. The powder distributing device of the present invention is capableof evenly distributing an alloy powder delivered by the powder conveying device into multiple portions, and delivering the powder portions respectively into the powder conveying pipes of the nozzle,a gas released from the gas source carries the alloy powder and delivers the alloy powder into a molten bath; and each of the powder conveying pipes sprays powder toward the central axis of the nozzle, and the convergence effect is good.

Description

technical field [0001] The invention relates to laser cladding equipment, in particular to a laser cladding powder feeding device. Background technique [0002] Laser cladding is to focus high-energy laser on the surface of alloy powder and substrate to form a molten pool and rapidly cool and solidify to form a coating with good metallurgical bonding. It can not only improve the wear resistance, corrosion resistance and oxidation resistance of the substrate surface, but also The damaged workpiece is repaired to restore the use function of the workpiece. This technology has been widely used in the field of workpiece surface treatment and parts remanufacturing repair. [0003] When the existing laser cladding equipment transports the powder material, it cannot accurately transport the powder to the molten pool, which not only causes a waste of alloy powder, but also has poor powder convergence, and many powders cannot directly enter the molten pool, resulting in laser claddin...
