Abstract

Die vorliegende Erfindung betrifft ein Verfahren zur Herstellung eines Blechumformbauteils aus einer Platine 1 mittels U-O Formen, wobei zunächst eine Vorform durch das U-Formen erzeugt wird und anschließend eine Endformgebung zu einer Endform durch das O-Formen durchgeführt wird. Die Erfindung ist gekennzeichnet durch folgende Verfahrensschritte:• Bereitstellen einer ebenen Platine 1,• U Formen der Platine 1 zu einer U Vorform,• Endkonturnahes Beschneiden der U Vorform,• Einlegen der U-Vorform in ein Zwischenformwerkzeug 1 und Anbiegen der abstehenden Schenkel 8, insbesondere der Enden 9 der U-Form, wobei ein Füllkörper 13 in der U-Vorform platziert ist und die Schenkel 8 den Füllkörper 13 abschnittsweise übergreifen und nach dem Anbiegen aus der Vorform herausgezogen wird, dergestalt, dass eine elastische und optional plastische Deformation der angebogenen Enden erzeugt wird,• O-Formen der so hergestellten Zwischenform 16.
