Abstract (en)
1. A machine for the recharging of mechanical components using the "plasma" method, of the type comprising a torch (4) and a powder distributor (2), with a rotary disc (22) having a vertical axis (23) and a scraper (27) for the supply of the torch (4), the powder being removed towards the periphery of the disc (22) and flowing from there via a conduit (5, 6) to the torch (4), characterised in that the powder distributor comprises at least one gas injector (31) comprising a receiver in the form of a funnel (33) disposed below the periphery of the rotary disc (22) and rising above a diffusor (32) with a lateral gas inlet (37) and gas intake apertures (38), the shape of the diffusor (32) and the arrangement of the intake apertures (38) being such that a gas eddy is created, into which the powder is sprayed, an outlet (40) disposed at the base of the injector (31) under the diffusor (32) being connected, via the conduit (5, 6), to the torch (4).
Abstract (fr)
Cette machine comprend une torche (4) alimentée par des conduits (5, 6) depuis un distributeur de poudre (2) à disque rotatif et racleurs. Ce distributeur comporte deux injecteurs de poudre (31), à gaz, disposés au-dessous du disque rotatif et ayant leur sortie reliée à un des conduits (5, 6). L'approvisionnement en poudre est assuré au moyen de deux bocaux (12), mis en service alternativement au moyen d'un tiroir (10). La torche (4) est supportée par un ensemble mobile (3) comprenant une commande de translation horizontale (43) et une commande de translation verticale (44). Cette machine permet le rechargement par projection, ainsi que le rechargement soudé.
