Abstract: A rotary swaging machine comprises a tool unit having a tool space which receives a plurality of shaping swaging tools. The swaging tools are used for processing a workpiece which can be introduced into the tool space. A front cover locking mechanism of the tool unit includes an actuation device and is provided for locking a front cover of the tool unit in a position in which the front cover at least partially covers the tool space at a tool space side. In order to change swaging tools, the front cover can be unlocked and moved into a position in which the front cover releases the tool space for removal or insertion of swaging tools at the tool space side.

Abstract: The invention relates to a device for correcting a profile bevel error, in particular the tooth alignment error of the gear (V) of a workpiece (W), wherein said device (1) comprises a clamping device (3) for the workpiece (W), a tool (4) and at least one advancing device (7, 7?) generating the relative movement between the workpiece (W) and the tool (4). The inventive device is characterized in that it comprises a guide device (10, 10?) for the tool (4) and/or for the clamping device (3) which enables to carry out the rotating movement of the tool (4) and/or clamping device around the workpiece (W) axis (X) extending in an advance direction, wherein said rotating movement acts as a compensating movement.

Abstract: The invention relates to a forming tool, in particular a kneading tool, which has a base body (12?), in which at least one forming element (21) is disposed, inclined at a first angle of inclination (?1) to a central axis (M) of the deformation tool (12), which results in the determination of an inlet chamfer (S) of the forming element (12).

Abstract: 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 an

Abstract: 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).

Abstract: A swaging machine for swaging a workpiece as it is axially fed or for recessing a workpiece when it is axially fixed and which comprises two or more dies and two or more stems for actuating said dies, die guiding means for guiding said dies, a front cover for covering said dies, and wedges extending between said stems and dies to vary the radial spacing of said dies and stems. The machine is provided with a die changing mechanism comprising a pivotally movable or displaceable die handling member, which is formed with juxtaposed chamber, which contain respective gripping means for gripping respective sets of dies, and said die handling member is pivotally movable or displaceable to a plurality of positions in which respective ones of said chambers are centered on a predetermined workpiece feeding axis.
