Title
(DE) VERFAHREN UND VORRICHTUNG ZUM DRÜCKUMFORMEN VON WERKSTÜCKEN
(EN) METHOD AND DEVICE OF SHAPING WORKPIECES BY COMPRESSION

Abstract
(DE)
Die Erfindung betrifft ein Verfahren zum Drückumformen, insbesondere Drücken, Zylinderdrückwalzen und Projizierdrückwalzen von Werkstücken sowie eine Vorrichtung hiefür, wobei ein Werkstück (5) in einer Spanneinrichtung (23) eingespannt und rotiert und durch zumindest ein Drückwerkzeug (4) umgeformt wird. Insbesondere ist eine Laserstrahleinrichtung (8) vorgesehen, durch die das Werkstück mit einem Laserstrahl (6) beaufschlagt und erwärmt wird, um die Fließspannung zu senken und das Formänderungsvermögen zu verbessern, sowie eine Wärmebehandlung durchzuführen.
(EN)
The invention concerns a method of shaping workpieces by compression, in particular pressing, cylinder press rolling and projection press rolling, and a device for carrying out this method. A workpiece (5) is clamped in a clamping device (23), rotated, and shaped by at least one pressure tool (4). In particular, a laser beam arrangement (8) is provided by means of which a laser beam (6) acts on the workpiece which is heated in order to decrease the yield stress and improve the deformability and so that a heat treatment can be carried out.
(FR)
L'invention concerne un procédé de façonnage de pièces par compression, notamment de repoussage, de fluotournage et d'emboutissage à projection, ainsi qu'un dispositif approprié. Ledit procédé consiste à serrer une pièce (5) dans un dispositif de serrage (23), à la faire tourner et à la façonner au moyen d'au moins un outil de repoussage (4). En particulier, un système à faisceau laser (8) dirige un faisceau laser (6) sur la pièce et la réchauffe, afin de réduire la contrainte d'écoulement, d'améliorer la capacité de déformation et d'effectuer un traitement thermique.
