Abstract

A method for reducing the sticky powder on the side surface of laser additive manufacturing parts. Four automatic powder switches are arranged at the outlet of the powder distributor, the recovery passage of each automatic powder switch is connected with the powder recovery cylinder, and the powder feeding passage is connected with the powder nozzle in the powder nozzle. The two rear powder feeding tubes and the two front powder feeding tubes are connected; the laser beam starts to move, and the two automatic powder switches connected with the two rear powder feeding tubes are switched to the recovery passage, which is connected with the two front powder feeding tubes. The two connected automatic powder switches are switched to the powder feeding path, and the powder is transported to the parts for solidification and deposition; the laser beam moves to the middle position of the parts, and the two automatic powder switches connected to the two rear powder feeding pipes are switched to the powder feeding path, The two automatic powder switches connected to the two front-side powder feeding pipes are switched to the recovery channel, and the powder is transported to the part for solidification and deposition; the laser beam moves to the front-side position of the part, and the single-channel cladding channel deposition ends; repeat until the desired part is formed The present invention reduces the sticky powder on the surface of the formed parts and improves the surface quality.

Description

technical field [0001] The invention belongs to the technical field of advanced manufacturing, and in particular relates to a method for reducing sticky powder on the side surface of a laser additive manufacturing part. Background technique [0002] Laser Directed Energy Deposition is a synchronous powder feeding laser additive manufacturing technology, which uses a high-energy laser beam to melt and rapidly solidify the synchronously transported metal powder in-situ metallurgically, and accumulate point by line layer by layer to form solid parts. Laser directed energy deposition has important application prospects in the fields of near-net shaping, coating and parts repair of large parts. [0003] In the laser directed energy deposition process, there are complex physical phenomena between the laser, the powder and the substrate (or forming part). Under the action of the laser beam, when the heated and partially melted powder hits the hot substrate (or forming part), it is...
