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 invention provides a laser cladding powder feeding device, which includes a powder material bin, a powder material conveying device and a nozzle, the output port of the powder material bin communicates with the feed port of the powder material conveying device, and a hollow laser passage is arranged inside the nozzle , the nozzle is provided with a number of penetrating powder feeding pipes, the outlet of the powder feeding device is connected with the powder feeding pipe, and the powder feeding device transfers the powder from the powder silo to the powder feeding pipe; it also includes a powder distribution device and air source; the input end of the powder material distribution device is connected with the discharge port of the powder material conveying device, and the output end of the powder material distribution device is connected with the powder feeding pipeline; the air source is connected with the nozzle. The powder distributing device of the present invention can divide the alloy powder sent by the powder conveying device into multiple parts equally, and send them to the powder feeding pipeline on the nozzle respectively, and the gas released by the gas source carries the alloy powder and sends it into the melting pool Middle; each powder feeding pipe sprays towards the central axis of the nozzle, and its convergence effect is better.

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...
