Abstract

Verfahren zur Herstellung von Preßteilen, insbesondere von Schneidplatten aus Hartmetall durch Pressen von Metallpulver und anschließendes Sintern des Preßlings, insbesondere von Wendeschneidplatten, die eine Sitzfläche und mindestens eine annähernd parallel zur Sitzfläche verlaufende Schneidkante aufweisen, die von der Sitzfläche einen vorgegebenen Abstand hat, mit Hilfe einer eine Matrize (10) und einen Ober- (14) und einen Unterstempel (16) aufweisenden Presse, mit den Schritten:
  • Einfüllen einer vorgegebenen Menge an Metallpulver in die Matrizenbohrung, wobei der Unterstempel eine vorgegebene Einfüllposition in der Matrizenbohrung aufweist,
  • Verstellen des Unterstempels und des Oberstempels in eine vorgegebene erste bzw. zweite Position,
  • weiteres Verstellen des Unterstempels und gegebenenfalls des Oberstempels und gleichzeitiges Messen der Preßkraft mindestens des Unterstempels, wobei die Verstellung von Unterstempel bzw. Oberstempel entlang einer vorgegebenen Sollkurve für die Preßkraft erfolgt
  • Beenden der Zustellbewegung von Unterstempel und gegebenenfalls des Oberstempels, wenn ein vorgegebener Wert für die Preßkraft erreicht wird.
