Abstract
Die Erfindung bezieht sich auf ein Verfahren zur Pressparameteranpassung einer Keramik- oder Metallpulverpresse bzw. eine damit ausgestattete Keramik-oder Metallpulverpresse, wobei in einer Matrizenöffnung einer Matrize (0) mittels auf Stempelträgern (1, 2, 3, 4) getragenen Stempeln (17, 18, 7, 8) aus Pulver (P) ein Presskörper auf ein vorgegebenes Presskörpermaß (dTEnd) gepresst wird, wobei während des Pressens zum Pressen eines solchen Presskörpers ein Stellglied (29) längs einer Abfolge von Sollwerten (dsoll(t)) geregelt wird, wobei eine Einhaltung der Abfolge von Sollwerten geprüft wird und bei einer Abweichung von Sollwerten eine Nachregelung des Stellglieds (29) durchgeführt wird, wobei zum Vergleich mit den Sollwerten ein Abstand (d(t)) zwischen einem ersten Messpunkt (m1; m2) an einem Festanschlag (20; 21), welcher einen der Stempelträger (1; 2) auf einer Seite der Matrizenöffnung abstützt, und einem zweiten Messpunkt (m3; m4) an einem Festanschlag (22; 23), welcher einen der Stempelträger (3; 4) auf einer dazu gegenüberliegenden Seite der Matrizenöffnung abstützt, gemessen wird. The invention relates to a method for adjusting the press parameter of a ceramic or metal powder press or a ceramic or metal powder press equipped therewith, wherein stamps (17, FIGS. 18, 7, 8) of powder (P) a compact is pressed to a predetermined compact size (dT end ), wherein during pressing for pressing such a compact an actuator (29) along a sequence of target values (d soll (t)) in which compliance with the sequence of nominal values is checked and a readjustment of the actuator (29) is carried out in the event of a deviation from nominal values, a distance (d (t)) between a first measuring point (m1; m2 ) on a fixed stop (20; 21), which supports one of the punch carriers (1; 2) on one side of the die opening, and a second measuring point (m3; m4) on a fixed stop (22; lcher one of the punch carrier (3; 4) is supported on an opposite side of the die opening, is measured.
