Abstract

Bei einem Verfahren zum Herstellen von Werkstücken nach dem Innenhochdruck-Umformverfahren aus einem Halbzeug mit einer Prozeßführung unter Berücksichtigung des Axialstempelweges bzw. der Axialstempelkraft für den Innendruck, wird der Umformprozeß mit einer Abhängigkeit zwischen dem zugeführten Volumenstrom und dem Axialstempweg bzw. der Axialstempelkraft geregelt.In a process for producing workpieces using the hydroforming process from a semi-finished product with a process control under consideration of the axial ram path or the axial ram force for the internal pressure the forming process with a dependency between the volume flow supplied and the Axialstempweg or the Axialstempelkraft regulated.
