Abstract

Gemäß der Erfindung werden beim Walzen von metallischen Werkstücken mit demselben wenigstens einen Werkzeug oder denselben Oberflächen der Walzen durch Einstellen unterschiedlicher Verläufe der Soll-Relativlage in unterschiedlichen Umformphasen unterschiedliche Umformungen derselben oder unterschiedlicher Werkstücke erzeugt, insbesondere durch Verringern des Abstandes der Drehachsen (A,B) während zumindest eines Teils der Umformphasc, und/oder Abweichungen beim Werkzeug von einer vorgegebenen Form durch Anpassen der Soll-Relativlage der Drehachsen der Walzen (2,3) wenigstens annähernd ausgeglichen.

Figure imgaf001
According to the invention, when rolling metallic workpieces with the same at least one tool or the same surfaces of the rolls, different deformations of the same or different workpieces are produced by setting different courses of the desired relative position in different forming phases, in particular by reducing the distance of the rotary axes (A, B). during at least part of the Umformphasc, and / or deviations in the tool of a predetermined shape by adjusting the desired relative position of the axes of rotation of the rollers (2,3) at least approximately balanced.
