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.The present invention relates to a method for producing a sheet metal forming component from a circuit board 1 by means of U-O forming, wherein a preform is first produced by U-forming and then final shaping to a final shape is carried out by O-forming. The invention is characterized by the following process steps: • Providing a flat board 1, • U-forming the board 1 into a U preform, • Trimming the U preform close to the final contour, • Inserting the U preform into an intermediate molding tool 1 and bending the protruding legs 8, in particular the ends 9 of the U-shape, with a packing body 13 being placed in the U-shaped preform and the legs 8 overlapping the packing body 13 in sections and being pulled out of the preform after the bending, in such a way that an elastic and optionally plastic deformation of the bent ends is created, • O-shapes of the intermediate shape 16 produced in this way.
