Abstract

Die Erfindung betrifft ein Verfahren zur Endpositionsreglung einer Presse für maßgenaue Formkörper. Das Verfahren ist insbesondere für hydraulische Kalibrier- oder Pulverpressen vorgesehen. Während eines Pressvorgangs wird ein charakteristischer Presswert in Abhängigkeit von einem anderen charakteristischen Presswert gemessen und die Endposition des Stempels in Abhängigkeit von der Messung korrigiert. Als charakteristischer Presswert wird beispielsweise eine Presskraft an einer vorgegebenen Stempelposition s1 gemessen. Ist ein zu pressender Formkörper (20) zu dick, so ist die Presskraft an der Stempelposition s1 erhöht und der Stempel (10) wird um den Korrekturwert über eine Soll-Endposition s0 hinweg verfahren, so dass der Formkörper (20) nach dem Pressen/Kalibrieren eine Soll-Dicke aufweist. Das erfindungsgemäße Verfahren hat den Vorteil einer höheren Maßgenauigkeit.

The invention relates to a method for Endpositionsreglung a press for dimensionally accurate shaped body. The method is intended in particular for hydraulic calibration or powder presses. During a pressing operation, a characteristic pressing value is measured as a function of another characteristic pressing value and the end position of the punch is corrected as a function of the measurement. As a characteristic press value, for example, a pressing force at a predetermined punch position s 1 is measured. If a molded body (20) to be pressed is too thick, the pressing force at the punch position s 1 is increased and the punch (10) is moved beyond the setpoint end position s 0 by the correction value, so that the shaped body (20) after the Pressing / calibrating has a desired thickness. The method according to the invention has the advantage of a higher dimensional accuracy.
