Abstract

Presse zur Herstellung von Preßlingen aus Pulvermaterial mit einer auf einem in einem Pressengestell angeordneten Matrizentisch aufspannbaren Matrize, in der ein Formhohlraum mit Hinterschneidung ausgebildet ist, mindestens einem Ober- und einem Unterstempel, die mit dem Formhohlraum zusammenwirken, wobei der Formhohlraum durch mindestens einen Schieber, Querpreßstempel oder ein bewegliches Teil der Matrize begrenzt ist, welcher quer zur vertikalen Achse von Ober- und Unterstempel (Hauptpreßachse) verschiebbar ist, und im Pressengestell angebrachten Verstellantrieben für Ober- und Unterstempel und den Schieber bzw. den verschiebbaren Matrizenteil, dadurch gekennzeichnet, daß ein Sensor Ist-Zustände des Verstellantriebs für den Schieber, Querpreßstempel oder dem verschiebbaren Matrizenteil mißt, die Ist-Zustände in einer Regelvorrichtung mit einem Sollwert verglichen werden und die Regelvorrichtung den Verstellantrieb für den Schieber, den Querpreßstempel oder den verschiebbaren Matrizenteil über die Energiezufuhr zum Verstellantrieb nach Maßgabe der Differenz von Ist- und Sollzustand betätigt wird.

Figure imgaf001
A press for producing compacts of powder material having a die clampable on a die table arranged in a press frame, in which a mold cavity with an undercut is formed, at least one upper and one lower punch cooperating with the mold cavity, the mold cavity being defined by at least one slide, Querpreßstempel or a movable part of the die is limited, which is displaceable transversely to the vertical axis of upper and lower punch (Hauptpreßachse), and mounted in the press frame adjustment drives for upper and lower punch and the slide or the displaceable die part, characterized in that a Sensor actual states of the adjustment for the slide, Querpreßstempel or the displaceable die part measures, the actual conditions are compared in a control device with a target value and the control device the adjustment drive for the slide, the Querpreßstempel or verschiebb aren Matrizenteil is actuated via the power supply to the adjustment in accordance with the difference between the actual and desired state.
