Title (DE) VORRICHTUNG UND VERFAHREN ZUM BIEGEN EINES PROFILS UND GEBOGENES PROFIL
(EN) DEVICE AND METHOD FOR BENDING A PROFILE AND BENT PROFILE
(FR) DISPOSITIF ET PROCÉDÉ DE CINTRAGE D'UN PROFILÉ ET PROFILÉ CINTRÉ
Abstract:
(DE) Die Erfindung betrifft eine Vorrichtung zum Biegen eines U- oder L-Blechprofils (1) zu einer winkelförmigen insbesondere rechtwinkligen Ecke, wobei das Profil an einem bzw. beiden Längsrändern der Basisfläche (2) eine vorzugsweise rechtwinklig abgebogene randförmige Schenkelfläche (3) aufweist, deren Breite (Bs) geringer ist als die Breite der Basisfläche (BB), wobei zwei relativ zueinander bewegliche Spannejnricbtungen insbesondere zwei Spannbackenpaare vorgesehen sind, zwischen denen die beiden, die Ecke bildenden Profilbereiche (5,6) einspannbar sind und durch die das Profil zur Ecke umbiegbar ist, und dass im Bereich des Scheitelpunktes (S) der Ecke ein Stempel (8) an der Außenseite der Schenkelfläche (3) angeordnet ist, dessen Bewegungsrichtung parallel zur Knickkante (4) der Ecke derart verläuft, dass der Stempel (8) von außen auf die Schenkelfläche drückt, um.die Schenkelfläche (3) während des Abbiegens des Profils (1) zu einer einwärts gerichteten Einbuchtung (7) einzubiegen, die beim weiteren Biegen des Profils (1) zu einer einwärts gerichteten Falte (9) formbar ist. Femer betrifft die Erfindung ein entsprechendes Verfahren zum Biegen eines U- oder L-Blechprofils (1) und das Profil selber (1).
(EN) The invention relates to a device for bending a U- or L-shaped sheet profile (1), to give an angular in particular right-angular corner, wherein the profile comprises an edge-forming arm surface (3) on one or both long edges of the base surface (2), preferably bent at right angles, the width (Bs) of which is less than the width of the base surface (BB), wherein two clamping devices which move relative to each other, in particular two clamping jaw pairs are provided, between which both profile regions (5, 6) which form the corners may be clamped and the profile bent to give the corners and a die (8) is arranged on the outside of the apex surface (3) in the region of the apex (S) of the corner the direction of movement of which runs parallel to the fold edge (4) for the corner such that the die (8) presses from outside on the arm surface in order to bend the arm surface (3) during the bending of the profile (1) to give an inwards directed indentation (7) which on further bending of the profile (1) can be shaped to give an inwardly facing fold (9). The invention further relates to a corresponding method for bending a U- or L-shaped profile (1) and the corresponding profile (1).
(FR) L'invention concerne un dispositif permettant de cintrer un profilé en tôle en U ou en L pour obtenir un coin, en particulier à angle droit, le profilé présentant, sur un bord longitudinal ou sur les deux bords longitudinaux de la surface de base, une surface de branche formant un bord et pliée de préférence à angle droit, dont la largeur est inférieure à celle de la surface de base. Des dispositifs de serrage mobiles l'un par rapport à l'autre comportent en particulier deux paires de mâchoires de serrage, entre lesquelles les deux parties du profilé formant le coin peuvent être serrées et au moyen desquelles le profilé peut être cintré pour former le coin. Un tampon est placé sur la face extérieure de la surface de branche au niveau de l'apex du coin, tampon dont le sens de déplacement s'étend parallèlement à l'arête de pliage du coin, de sorte que le tampon applique une pression, de l'extérieur, sur la surface de branche afin de cintrer la surface de branche pendant le cintrage du profilé de manière à former un creux tourné vers l'intérieur, qui peut être façonné en un pli vers l'intérieur lors d'un autre cintrage du profilé. L'invention concerne également un procédé correspondant pour le cintrage d'un profilé en tôle en U ou en L et le profilé lui-même.
