Abstract

Per perfezionare un dispositivo per il rivestimento di superfici di pezzi, comprendente un'ottica focalizzante un raggio laser su un punto focale su una superficie del pezzo e una testa di applicazione della polvere applicante una polvere di rivestimento a forma di getto di polvere sulla superficie nella regione del punto focale, in modo che con esso sia generabile un getto di polvere delimitabile il più esattamente possibile e quindi utilizzabile ottimalmente, viene proposto che la testa di applicazione della polvere presenti un separatore polvere-gas, il quale separa in polvere di rivestimento e veicolo gassoso un miscuglio di polvere di rivestimento e veicolo gassoso alimentato alla testa di applicazione della polvere, e che sia previsto un ugello che trasforma la polvere di rivestimento uscente dal separatore polvere-gas in un getto di polvere presentante una geometria definita, con riduzione del veicolo gassoso.To perfect a device for coating surfaces of pieces, comprising an optic focusing a laser beam on a focal point on a surface of the piece and a powder application head applying a powder coating of powder-shaped coating on the surface in the region of the focal point, so that with it a jet of powder that can be delimited as exactly as possible and therefore optimally usable can be generated, it is proposed that the powder application head has a dust-gas separator, which separates into powder coating and gaseous vehicle a mixture of coating powder and gaseous vehicle fed to the powder application head, and that a nozzle is provided which transforms the coating powder leaving the dust-gas separator into a jet of powder having a defined geometry, with reduction of the gaseous vehicle.
