Cross-wedge rolling machine and method for cross-wedge rolling

摘要

The invention relates to a cross-wedge rolling machine, comprising:– at least two rotatable in the same direction or rotating in the same sense, with the tools (20, 21, 30, 31) includes or equipped work rolls (2, 3) for shaping a between the working rolls (2, 3), which can be arranged or arranged workpiece (10.1, 10.2);– at least one drive device for driving the drive rollers (2, 3) with one or more variable parameters, in particular with a variable rotational speed (n);– at least one separating agent feed (22, 32) for the supply of the separating agent to the work rolls (2, 3) with an adjustable separating agent application (sa);– a control - and / or regulating device, which is designed for this purpose both the drive device as well as the separating agent application (sa) to control and / or regulated, whereby the control - and / or closed-loop control device the separating agent application (sa) in dependence on the one or more of the variable parameters and / or the contours of the tool controls and / or regulates.
