Abstract

Es wird ein Verfahren zum hydromechanischen Tiefziehen von Metallblech (10) beschrieben, bei dem das Blech (10) in der Trennebene zwischen einem Oberwerkzeug (5) und einem Unterwerkzeug (2), von denen eines die Formkontur aufweist, flüssigkeitsdicht eingespannt, mittels Druckgas in Umformrichtung beaufschlagt und vorgeformt und anschließend in gleicher Richtung mittels des die Formkontur aufweisenden Werkzeugs gegen ein hydraulisches Kissen in dem anderen Werkzeug endgeformt wird. Ferner ist eine Vorrichtung zur Durchführung des Verfahrens beschrieben.

Figure 00000001
A method for hydromechanical deep drawing of metal sheet (10) is described, in which the sheet (10) is clamped in a liquid-tight manner in the parting plane between an upper tool (5) and a lower tool (2), one of which has the shape contour, by means of compressed gas Forming direction acted upon and preformed and then in the same direction by means of the tool having the shape contour is finally formed against a hydraulic cushion in the other tool. Furthermore, an apparatus for performing the method is described.
