Abstract

Bei einer Rotationsumformmaschine (1) wird die Relativbewegung zwischen einem Werkstück und ein oder zwei Walzen (3,4) so beeinflusst, dass an den Walzen (3, 4) vorhandene Stempel (8) an ausgewählten Punkten (P0) eine Zykloidenbewegung durchführen, bei der der Flächeninhalt vorhandener Schleifen reduziert oder Schleifen ganz vermieden werden. Dadurch kann der Flankenverschleiß der Stempel (8) vermindert werden. Darüberhinaus kann die Qualität der erzeugten Werkstücke (11) verbessert werden. Ergänzend kann an der Flanke (34) des Stempels (8) eine Ausnehmung angeordnet sein, die das Schwenken des Stempels bei seiner Eintauchbewegung in das Werkstück (11) ohne erhöhten Flankendruck gestattet.
