The present invention relates to a device for forming, in particular for cold forming, here in particular for cold extruding, 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 the workpiece and/or the forming die pass through a first stroke travel in the feeding direction, a movement of the forming die and/or of the workpiece can be effected in a subsequent reverse stroke, over a second stroke travel in a direction opposite to the feeding direction, and to a method for forming a workpiece wherein a relative movement between the workpiece and a forming die is generated by a feed device, which relative movement between the workpiece and the forming die, produced by the feed device, is modulated in such a way that following a forward stroke in which the workpiece and/or the forming die pass through a first stroke travel, a movement of the forming die and/or of the workpiece can be effected in a subsequent reverse stroke, over a second stroke travel in a direction opposite to the feeding direction.
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.
Method for forming a workpiece wherein a relative movement between the workpiece and a forming die is generated by a feed device, which relative movement between the workpiece and the forming die, produced by the feed device, is modulated in such a way that following a forward stroke in which at least one of the workpiece and the forming die pass through a first stroke travel in the feed direction, a movement of at least one of the forming die and the workpiece, effected in a subsequent reverse stroke over a second stroke travel in a direction opposite to the feeding direction, is modulated by a frequency generating device in such a way that the stroke travels of at least one of the forward strokes and the reverse strokes of at least two successive forming steps, each being composed of a forward stroke and a reverse stroke, are different.
