Abstract

Zur Hubfrequenzsteuerung einer Schmiedemaschine (1), die einen mechanischen Hubantrieb (3) für die Hubbewegung eines Schmiedestempels (2) und eine hydraulische Antriebsverbindung (4) zwischen Hubantrieb (3) und Schmiedestempel (2) aufweist, wird die Drehzahl des Hubantriebes (3) auf eine hohe Hubfrequenz des Schmiedestempels (2) abgestimmt und zur Verringerung der Hubfrequenz der Hydraulikdruck der Antriebsverbindung (4) bei gleichbleibender Drehzahl des Antriebes (3) für periodisch aufeinanderfolgende Antriebshübe im Maße des antriebsbedingten Ansteigens abgebaut, während gleichzeitig vorzugsweise der Schmiedestempel (2) im oberen Totpunktbereich blockiert wird. Dazu ist die Antriebsverbindung (4) über ein in Abhängigkeit von der Hubbewegung betätigbares Schaltventil (23) an einem Druckspeicher (20) angeschlossen.
