Abstract

Es wird eine hydraulische Presse vorgeschlagen, in der mehrere Preßkolben (1 bis 5) angeordnet sind, die unab­ hängig voneinander und relativ zueinander beweglich an­ geordnet sind. Die mit mehreren Preßkolben (1 bis 5) ausgestattete hydraulische Presse ermöglicht während des Verpressungsvorganges eine Verdichtung von Preßtei­ len (6) aus feinkörnigen Stoffen mittels als Preßstem­ pel ausgebildeten Preßwerkzeugen, wobei das Verfahren des Verbundpressens die Kombination der Bewegungsabläu­ fe der bisher bekannten, unterschiedlichen Preßmethoden sowohl als Einzelschritt wie auch als übergreifenden Fertigungsablauf zuläßt. A hydraulic press is proposed in which several plungers (1 to 5) are arranged, the unab dependent on each other and movable relative to each other are ordered. The one with several plungers (1 to 5) equipped hydraulic press allows during the compression process a compression of pressed parts len (6) from fine-grained materials by means of a press pel trained pressing tools, the process of composite pressing, the combination of movement stagnation Fe of the previously known, different pressing methods both as a single step and as a comprehensive one Allows manufacturing process.
