Abstract

Die Erfindung betrifft eine hydraulische Schließvorrichtung zum Querfließpressen von Werkstücken, mit zwei relativ zueinander bewegbaren und miteinander verschließbaren Matrizenhälften (22, 42) und zwei mit gleichen Geschwindigkeiten relativ zu den geschlossenen Matrizenhälften bewegbaren Preßstempeln, wobei ein erster Hydraulikkolben (16), an dem die erste Matrizenhälfte (22) angeordnet ist, in einem axial bewegbaren ersten Hydraulikzylinder (6), an dem der erste Preßstempel (20) angeordnet ist, verschiebbar lagert, und ein zweiter Kolben (36) in einem raumfesten zweiten Hydraulikzylinder (26) verschiebbar lagert. Sie ist dadurch gekennzeichnet, daß die zweite Matrizenhälfte (42) raumfest angeordnet ist, während der zweite Preßstempel (40) am zweiten Hydraulikkolben (36), der beim Querfließpressen des Werkstückes durch ein vom ersten Hydraulikkolben (16) verdrängbares Druckmittel beaufschlagbar ist, sitzt.
