Abstract

Bei einer Presse, die einen oberen und einen unteren Drehteller (2, 3) für Werkzeuge (4, 5) aufweist, können die einzelnen Oberwerkzeuge (4) in der jeweiligen Drehstellung des oberen Drehtellers (2) mit einem Pressenstempel (6) gekuppelt werden. Um eine freie Zugänglichkeit im Bereich der Unterwerkzeuge (5) zu erhalten, sind diese jeweils für sich axial verschiebbar im unteren Drehteller (3) gelagert, wobei lediglich das in der Arbeitsstellung befindliche Unter­ werkzeug (5) im Gestell (1) abgestützt ist, während die anderen Unterwerkzeuge abgesenkt werden. For a press that has an upper and a lower one Turntable (2, 3) for tools (4, 5), the individual upper tools (4) in the respective rotary position the upper turntable (2) with a press ram (6) be coupled. To ensure free access in the area of the lower tools (5), they are each for is axially displaceable in the lower turntable (3), only the sub in the working position Tool (5) in the frame (1) is supported while the other lower tools can be lowered.
