(EN) METHOD FOR PRE-SHAPING SHEET METAL, AND COMPUTER PROGRAM AND DEVICE FOR CARRYING OUT THE METHOD
(FR) PROCÉDÉ POUR FAÇONNAGE PRÉALABLE DE TÔLE, ET PROGRAMME INFORMATIQUE ET DISPOSITIF POUR LA MISE EN ŒUVRE DU PROCÉDÉ
Abstract
(DE) Verfahren zur Vorformung von Metallblech (1) in Form von Bändern oder Platten mit einem flachen Querschnittsprofil zu einem kreisbogenförmigen Querschnittsprofil in einer Vorformstrecke (3) einer Anlage zur Herstellung von Schlitzrohren, wobei dem Metallblech (1) in der Vorformstrecke (3) durch Walzprofilieren in mehreren in einer Transportrichtung aufeinanderfolgenden Biegeschritten das kreisbogenförmige Querschnittsprofil aufgegeben wird, wobei das Querschnittsprofil durch schrittweises Biegen einzelner Kreisbogenabschnitte (8) jeweils von einer Außenkante des Metallblechs (1) in Richtung auf eine Mittellinie (7) erzeugt wird, derart, dass die einzelnen Kreisbogenabschnitte (8) unmittelbar aneinander angrenzen oder sich wenigstens teilweise überlappen. Die Erfindung betrifft weiterhin eine Einrichtung zur Durchführung des Verfahrens.
(EN) The invention relates to a method for pre-shaping sheet metal (1) in strip- or panel-form having a flat cross-sectional profile into a circular arc-shaped cross-sectional profile, in a pre-shaping section (3) of a plant for producing open-seam pipes, wherein the circular arc-shaped cross-sectional profile is provided to the sheet metal (1) in the pre-shaping section (3) by means of roll profiling in a plurality of successive bending steps in a transport direction, wherein the cross-sectional profile is created by step-by-step bending of individual circular arc portions (8) from an outer edge of the sheet metal (1) toward a centre line (7) such that the individual circular arc portions (8) directly adjoin one another or at least partially overlap. The invention further relates to a device for carrying out the method.
(FR) L'invention concerne un procédé pour le façonnage préalable d'une tôle (1) sous forme de bande ou de panneau ayant un profil de section transversale plat en un profil de section transversale en forme d'arc de cercle, dans une section de façonnage préalable (3) d'une installation pour la production de tuyaux à bords simplement rapprochés, le profil de section transversale en forme d'arc de cercle étant ménagé sur la tôle (1) dans la section de façonnage préalable (3) au moyen d'un profilage sur rouleaux dans une pluralité d'étapes de cintrage successives dans une direction de transport, le profil de section transversale étant créé par le cintrage étape-par-étape de parties d'arc de cercle individuelles (8) à partir d'un bord externe de la tôle (1) vers une ligne centrale (7) de telle sorte que les parties d'arc de cercle individuelles (8) sont directement adjointes mutuellement ou se chevauchent au moins partiellement. L'invention concerne en outre un dispositif pour la mise en œuvre du procédé.
