Patent ID: 8091400

Claim:
Device for forming a workpiece, which device has a forming die and a feed device by means of which a relative movement can be generated between the workpiece and the forming die, wherein the device has a frequency generating device which interacts with the feed device and by which the relative movement between the workpiece and the forming die, as generated by the feed device, can be modulated in such a way that following a forward stroke in which at least one of the workpiece and forming die pass through a first stroke travel in the feeding direction, a movement of at least one of the forming die and the workpiece can be effected in a subsequent reverse stroke, over a second stroke travel in a direction opposite to the feeding direction, characterized in that the frequency generating device modulates the feed device in such a way that at least one of the stroke travels of the forward strokes and the reverse strokes of at least two successive forming steps of the device, each being composed of a forward stroke and a reverse stroke, are different.
