Abstract
Implementations of the present invention relate to a method and a corresponding device for shaping a workpiece, in which the lifting of the workpiece from the tool after a shaping process is automated. One implementation of the method relates to (a) placing the workpiece in a shaping position on a first tool of the shaping machine, (b) moving the tools of the shaping machine toward one another, (c) shaping the workpiece between the tools, (d) subsequently moving the tools away from one another, (e) identifying a triggering time when the relative motion of the tools has reached a reference position.,(f) determining a lifting time, which may be a function of the triggering time, and (g) initiating a lifting motion of the workpiece from the first tool by at least one handling device at lifting time.
