Abstract

Die Erfindung betrifft ein Biegewerkzeug (4) für das Freiformbiegen von aus Blech zu fertigenden Werkstücken (2), mit einem Grundkörper (26), der einen Biegebereich (29) definiert, wobei im Querschnitt gesehen durch den Biegebereich (29) eine Werkzeugebene (30) verläuft. Im Biegebereich (29) ist auf einer Seite der Werkzeugebene (30) ein bezüglich des Grundkörpers (26) dazu verlagerbarer erster Werkstückstützteil (32) und auf der anderen Seite ein bezüglich des Grundkörpers (26) feststehender weiterer Werkstückstützteil (33) angeordnet bzw. ausgebildet. Ein dem Biegebereich (29) zugewendeter Endbereich (38) des ersten Werkstückstützteils (32) ist mit einer Stützkraft (F) beaufschlagt, welche der auf das zu formende Werkstück (2) einwirkenden Biegekraft (FB) entgegenwirkt oder es ist der dem Biegebereich (29) zugewendete Endbereich (38) des ersten Werkstückstützteils (32) selbsttätig entgegen der auf das zu formende Werkstück (2) einwirkenden Biegekraft (FB) rückstellbar ausgebildet.
