Title
(EN) HIGH-PRESSURE FLUID-JET CUTTING DEVICE AND METHOD WITH ABRASIVE REMOVAL SYSTEM
(FR) MACHINE ET PROCEDE POUR LE DECOUPAGE A JET DE FLUIDE HAUTE PRESSION, AVEC DISPOSITIF D'ELIMINATION DES PARTICULES ABRASIVES
Abstract
(EN)
A fluid jet-cutting machine (10) with an abrasive particle removal device and method. In one embodiment, the fluid-jet cutting machine (10) has a nozzle (22) and a carrier assembly (21) attached to the nozzle (22) to move the nozzle along a cutting path. A high-pressure fluid source (24) and an abrasive particle source (26) are coupled to the nozzle (22) to generate an abrasive fluid-jet (28) having a fluid and a plurality of abrasive particles for cutting a work-piece. The cutting machine (10) also has a particle removal device (40) including a tank (42) aligned with the nozzle (22), a settling container (46), and a fluid transport mechanism (44) to transport fluid from the tank (42) to the settling container (46). The tank (42) includes at least one compartment (56) configured to receive the fluid and the abrasive particles of the fluid-jet (28) along at least a portion of the cutting path. Additionally, the compartment (56) is configured to control fluid flow within the compartment (56) so that the fluid-jet suspends, and maintains the suspension, of at least a substantial portion of the abrasive particles in the one compartment without additional mechanical agitation. The fluid transport mechanism (44) can include a conduit with a first end in fluid communication with the compartment (56) and a second end outside of the compartment in fluid communication with the settling container (46). In operation, a portion of the fluid with suspended abrasive particles in the compartment (56) is transported through the conduit and into the settling container (46). The abrasive particles from the transported portion of fluid settle to a lower portion of the settling container (46) while a clarified fluid is removed from the settling container (46).

L'invention concerne une machine de découpage à jet de fluide (10) équipée d'un dispositif d'élimination des particules abrasives, et un procédé correspondant. Selon une variante, la machine (10) comporte une buse (22), et un ensemble support (21) fixé à la buse (22) qui permet de déplacer ladite buse le long d'un trajet de découpe. Une source de fluide haute pression (24) et une source de particules abrasives (26) sont couplées à la buse (22), de manière à produire un jet de fluide abrasif (28) et une pluralité de particules abrasives permettant de découper une pièce à travailler. Le dispositif d'élimination des particules abrasives (40), dont est aussi équipée la machine (10), comprend un réservoir (42) aligné avec la buse (22), un récipient de décantation (46), et un mécanisme de transfert de fluide (44) acheminant le fluide du réservoir (42) au récipient de décantation (46). Le réservoir (42) comporte au moins un compartiment (56) conçu pour recevoir le fluide et les particules abrasives du jet de fluide (25), au moins le long d'une partie du trajet de découpe. Par ailleurs, ce compartiment (56) est conçu pour contrôler son flux de fluide interne, si bien que le jet de fluide met en suspension au moins une partie substantielle des particules abrasives dans le compartiment (56), et il maintient la suspension, sans agitation mécanique supplémentaire. Le mécanisme de transfert de fluide (44) peut comporter un conduit dont une première extrémité communique avec le compartiment pour l'écoulement de fluide, et dont une seconde extrémité à l'extérieur du compartiment (56) communique avec le récipient de décantation (46) pour l'écoulement de fluide. En fonctionnement, une partie du fluide du compartiment (56) renfermant des particules abrasives en suspension est transférée au récipient de décantation (46) via le conduit. Les particules abrasives de la partie transférée se décantent dans une zone inférieure du récipient de décantation (46), tandis qu'un fluide clarifié est évacué dudit récipient (46).
