Abstract

Verfahren zur Herstellung von Pressteilen, insbesondere von Schneidplatten aus Hartmetall, durch Pressen von Metallpulver und anschließendes Sintern der Presslinge, bei dem die Presslinge in einer Pulverpresse geformt werden, die eine Matrizenplatte (12), einen Oberstempel (14) und mindestens einen Unterstempel (16) aufweist, die einer Matrizenbohrung zugeordnet und von einem hydraulischen Pressenzylinder betätigbar sind, wobei den Stempeln Kraftmessvorrichtungen und Wegmessvorrichtungen zugeordnet sind zur Messung der Presskräfte während des Stempelvorschubs bis zu den Endpositionen, wobei für einen Pressling vorgegebener Geometrie und Abmessungen sowie vorgegebenen Materials der Wert für die vom Oberstempel einzubringende Energie gespeichert wird, dass ferner als zweiter Wert die vom Ober- und Unterstempel (14,16) insgesamt einzutragende Energie gespeichert wird, dass der Vorschub des Oberstempels (14) beendet wird, wenn sein Energieeintrag den vorgegebenen ersten Wert erreicht hat und der Vorschub des Unterstempels (16) nach Maßgabe des Restenergieeintrags erfolgt und beendet wird, wenn die Gesamtenergie den vorgegebenen zweiten Wert erreicht hat.
