    摘要: Eine Transfereinrichtung (11) für eine Mehrstufenpresse weist zwei parallel zueinander an einem Träger (19) gelagerte Greiferschienen (12, 13) auf, die mit dem Träger (19) entlang einer Transferkurve bewegbar sind. Die Greiferschienen (12, 13) tragen paarweise einander zugeordnete Greiferfinger (14, 15), die durch gegenläufige Bewegung der Greiferschienen (12, 13) aufeinander zu und voneinander weg bewegbar sind. Die Zustellbewegung wird durch Parallelogrammgetriebe erzeugt, die zur Lagerung und zum Antrieb der Greiferschienen (12, 13) dienen. Die Parallelogrammgetriebe sind von einer einzigen Antriebsquelle (43) her über eine Kardanwelle (41) angetrieben, die die Ausführung der Transferbewegung ermöglicht, ohne daß dabei die Relativposition der Greiferfinger (14, 15) zueinander geändert würde. Eine solche Transfereinrichtung (11) ist an einer Seite der von den Werkzeugen (5) gebildeten Reihe angeordnet und ermöglicht somit einen guten Zugang zu den Werkstücken von der jeweils anderen Seite her. Bedarfsweise kann die gesamte Transfereinrichtung (11) aus dem Werkzeugbereich entfernt werden. Dies erfolgt vorzugsweise in einer Schwenkbewegung.
