Title
(DE) STRAHLFANGVORRICHTUNG FÜR EINE BEARBEITUNGSMASCHINE
(EN) JET TRAPPING DEVICE FOR A CUTTING MACHINE
(FR) DISPOSITIF DE CAPTURE POUR UNE MACHINE D'USINAGE
Abstract
(DE)
Die Erfindung betrifft eine Strahlfangvorrichtung für eine Schneidstrahl­Bearbeitungsmaschine mit einem Gehäuse (34), welches eine zum Schneidstrahl (24) weisende linienförmig ausgebildete Öffnung (31) aufweist, wobei der Schneidstrahl (24) beim Bearbeiten eines Werk­stücks (17) aus der Unterseite des Werkstücks austritt und durch die Öffnung (31) in das Gehäuse (34) eintritt, wobei die Öffnung (31) des Gehäuses (34) durch Eintrittskanten (54) ausgebildet ist, die durch zwei in einem Winkel von weniger als 900 zueinander angeordneten Flächen (34, 57; 61, 57) ausgebildet sind und die einander gegenüberliegenden Eintrittskanten (54) einen Abstand aufweisen, so dass sich die Eintritts­kanten (54) bis zum Schneidstrahl (24) erstrecken, jedoch der Schneid­strahl (24) im Wesentlichen berührungslos zwischen den beiden Ein­trittskanten (54) in das Gehäuse (34) eintritt.
(EN)
The invention relates to a jet trapping device for a jet cutter machine, comprising a housing (34), with a linear opening (31) facing the cutting jet (24), the cutting jet (24) exiting the lower side of the workpiece on machining a workpiece (17), the opening (31) in the housing (31) having entry edges (54) formed by two surfaces (34, 57; 61, 57), arranged at an angle of less than 900 to each other and the opposing entry edges (54) are at a separation such that the entry edges (54) extend to the cutting jet (24), the cutting jet (24) however essentially entering the housing (34) between the entry edges (54) without making contact.
(FR)
L'invention concerne un dispositif de capture de faisceau pour une machine d'usinage par faisceau de coupe, lequel dispositif présente un boîtier (34) pourvu d'une ouverture linéaire (31) orientée vers le faisceau de coupe (24), faisceau de coupe (24) qui, lors de l'usinage d'une pièce (17), sort de la pièce par sa face inférieure et entre dans le boîtier (34) par ladite ouverture (31). Selon cette invention, l'ouverture (31) du boîtier (34) est constituée par des bords d'entrée (54) formés par deux surfaces (34, 57 ; 61, 57) placées l'une par rapport à l'autre de manière à former un angle inférieur à 90° et les bords d'entrée opposés (54) sont placés à une certaine distance l'un de l'autre, de sorte que ces bords d'entrée (54) s'étendent en direction du faisceau de coupe (24), mais ce faisceau de coupe (24) entre dans le boîtier (34) sensiblement sans contact entre les deux bords d'entrée (54).
