Abstract (en)

Hydraulic cold pilger mill drive system regulation, using a timed proportional valve for pressurized medium supply to each hydraulic motor, is new. Regulation of a hydraulic rotary and advance drive, for a tube cold pilger mill stand, comprises regulating the pressurized hydraulic medium supply to each hydraulic motor by a proportional valve which opens for a time proportional to the travel distance of a drive mechanism moved by the motor.

Abstract (de)

Die Erfindung betrifft ein Verfahren zum Regeln eines hydraulischen Dreh- und Vorschubantriebes für ein Kaltpilgerwalzwerk zur Herstellung von Rohren in einem von einem Kurbeltrieb in Walzrichtung hin- und herbewegbaren Walzgerüst, dessen verjüngend kalibrierte Walzen mit wechselndem Drehsinn über dem Walzgut abrollen und das Rohr abhängig von der Stellung der Kurbelwelle zeitweise zum Vorschieben und Drehen freigeben, wobei das Drehen und Vorschieben des Rohres mittels den daran angreifenden Antriebsorganen zugeordneter druckmittelgeregelter Hydromotoren erfolgt, dadurch gekennzeichnet, dass die Druckmittelzufuhr jedes Hydromotors über ein Proportionalventil geregelt wird, das abhängig von dem geforderten Weg des von diesem Hydromotor bewegten Antriebsorgans für ein diesem Weg proportionales Zeitintervall geöffnet wird. <IMAGE>
