Device, in particular machine, for producing a wiegand wire from a wire, in particular a pulse wire, and method for operating a device

A device for producing a Wiegand wire and/or a pulse wire from a wire, comprising:

• a first clamping chuck;
• a second clamping chuck;
• a third clamping chuck;
• a first linear actuator;
• and
• a third linear actuator;
• wherein the clamping chucks are adapted to feed the wire therethrough, the wire being releasably connectable in a torsionally fixed manner to the three clamping chucks and/or connectable to the three clamping chucks in a releasable, torsionally fixed and nonpositive manner;
• wherein the clamping chucks are set apart from one another in a wire direction, the second clamping chuck being located between the first clamping chuck and the third clamping chuck in the wire direction;
• wherein the second clamping chuck is rotatably mounted to apply a torsion to a first wire section and to apply a reverse torsion to a second wire section, the first wire section being located between the first clamping chuck and the second clamping chuck, the second wire section being located between the third clamping chuck and the second clamping chuck;
• wherein the first linear actuator is adapted to control and/or regulate a distance in the wire direction between the first clamping chuck and the second clamping chuck;
• and
• wherein the second linear actuator is adapted to control and/or regulate a distance in the wire direction between the second clamping chuck and the third clamping chuck.

A Wiegand wire, wherein the Wiegand wire is produced using a device including:

• a first clamping chuck;
• a second clamping chuck;
• a third clamping chuck;
• a first linear actuator;
• and
• a third linear actuator;
• wherein the clamping chucks are adapted to feed the wire therethrough, the wire being releasably connectable in a torsionally fixed manner to the three clamping chucks and/or connectable to the three clamping chucks in a releasable, torsionally fixed and nonpositive manner;
• wherein the clamping chucks are set apart from one another in a wire direction, the second clamping chuck being located between the first clamping chuck and the third clamping chuck in the wire direction;
• wherein the second clamping chuck is rotatably mounted to apply a torsion to a first wire section and to apply a reverse torsion to a second wire section, the first wire section being located between the first clamping chuck and the second clamping chuck, the second wire section being located between the third clamping chuck and the second clamping chuck;
• wherein the first linear actuator is adapted to control and/or regulate a distance in the wire direction between the first clamping chuck and the second clamping chuck;
• and
• wherein the second linear actuator is adapted to control and/or regulate a distance in the wire direction between the second clamping chuck and the third clamping chuck;
• and/or
• wherein the Wiegand wire is produced using a method that includes:
• feeding a section of the wire to be processed through the three clamping chucks;
• operating and/or closing the clamping chucks to hold the wire by the clamping chucks in a nonpositive manner;
• rotating the second clamping chuck in an axis of rotation coaxially aligned to the wire direction;
• varying and/or enlarging a distance between the first clamping chuck and the second clamping chuck and between the third clamping chuck and the second clamping chuck;
• applying a current to the wire between at least two of the clamping chucks;
• and
• opening the clamping chucks and advancing the wire advanced so that a newly to be processed section of the wire is fed through three clamping chucks.
