Title (EN) METHOD AND DEVICE FOR STRAIGHTENING A WORKPIECE
(FR) PROCÉDÉ ET DISPOSITIF DE REDRESSAGE D’UNE PIÈCE
(DE) VERFAHREN UND VORRICHTUNG ZUM RICHTEN EINES WERKSTÜCKS
Abstract:
(EN) The invention relates to a method for straightening a workpiece (1) having a longitudinal axis, wherein the workpiece (1) is bent out from an initial position transverse to the longitudinal axis and bent back again. In order to create advantageous straightening conditions, it is proposed that the workpiece (1), which is held on the end side in mounting heads (6), is bent out by the mounting heads (6) in directions, which change in at least predetermined angle ranges, and bent back again.
(FR) L’invention concerne un procédé de redressage d’une pièce (1) pourvue d’un axe longitudinal, la pièce (1) étant pliée vers l’extérieur perpendiculairement à l’axe longitudinal à partir d’une position initiale puis ramenée dans cette position initiale. Afin de créer des conditions de redressage avantageuses, l’invention propose que la pièce (1) maintenue, côté terminal, dans des têtes de réception (6) soit pliée vers l’extérieur au moyen des têtes de réception (6) dans des directions, variables au moins dans des plages angulaires prédéfinies puis soit ramenée dans cette position initiale.
(DE) Es wird ein Verfahren zum Richten eines Werkstücks (1) mit einer Längsachse beschrieben, wobei das Werkstück (1) aus einer Ausgangslage quer zur Längsachse ausgebogen und wieder zurückgebogen wird. Um vorteilhafte Richtbedingungen zu schaffen, wird vorgeschlagen, dass das endseitig in Aufnahmeköpfen (6) gehaltene Werkstück (1) mithilfe der Aufnahmeköpfe (6) in sich zumindest in vorgegebenen Winkelbereichen ändernden Richtungen ausgebogen und wieder zurückgebogen wird.
