The invention relates to a device (1) for forming, in particular for cold forming, here in particular for cold extruding, a workpiece (2), which device (1) has a forming die (3) and a feed device (5), by means of which a relative movement can be generated between the workpiece (2) and the forming die (3), wherein the device (1) has a frequency generating device (10) which interacts with the feed device (5), by means of which frequency generating device (10) the relative movement between the workpiece (2) and the forming die (3) as generated by the feed device (5) can be modulated in such a way that, after a forward stroke in which the workpiece (2) and/or the forming die (3) passes through a first stroke travel in the feed direction (P), in a subsequent rearward stroke, a movement of the forming die (3) and/or of the workpiece (2) by a second stroke travel can be carried out in a direction counter to the feed direction (P). It is provided according to the invention that the frequency generating device (10) modulates the feed device (5) in such a way that the stroke travels of the forward strokes and/or of the rearward strokes of at least two successive forming steps, composed in each case of a forward stroke and a rearward stroke, of the device (1) are different. The invention also relates to a corresponding method for forming a workpiece.
Device (1) for forming, a workpiece (2), which device has a forming die (3) and a feed device (5) by means of which a relative movement can be generated between the workpiece (2) and the forming die (3), wherein the device (1) has a frequency generating device (10) which interacts with the feed device (5) and by which the relative movement between the workpiece (2) and the forming die (3), as generated by the feed device (5), can be modulated in such a way that following a forward stroke in which at least one of the workpiece (2) and forming die (3) pass through a first stroke travel in the feeding direction (P), a movement of at least one of the forming die (3) and the workpiece (2) can be effected in a subsequent reverse stroke, over a second stroke travel in a direction opposite to the feeding direction (P), characterized in that the frequency generating device (10) modulates the feed device (5) 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 (1), each being composed of a forward stroke and a reverse stroke, are different.
Method for forming a workpiece (2) wherein a relative movement between the workpiece (2) and a forming die (3) is generated by a feed device (5), which relative movement between the workpiece (2) and the forming die (3), produced by the feed device (5), is modulated in such a way that following a forward stroke in which at least one of the workpiece (2) and the forming die (3) pass through a first stroke travel in the feed direction (P), a movement of at least one of the forming die (3) and the workpiece (2), effected in a subsequent reverse stroke over a second stroke travel in a direction opposite to the feeding direction (P), is modulated by a frequency generating device (10) 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.
