Definitions

  • the invention relates to a straightener for rotating straightening of wire, with a rotating about an axis of rotation straightening, which receives a plurality of straightening devices, each having a directional nozzle comprising an inlet part, an outlet part and between the two at least one straightening unit, wherein the position of the straightening at least one straightening unit within the directional wing relative to the position of the directional nozzles adjacent straightening devices by a concentric with the axis of rotation of the straightening blade and independently of this and relative to this rotatable adjusting ring is adjustable.
  • Straightening devices for rotating wire straighten the wire as it travels at different levels to reduce or at least balance its residual stresses, ultimately resulting in as straight a wire as possible.
  • the DE 25 23 831 C3 describes a straightener with straightening wings, which although also allows during operation, the adjustment of the radial position of a central directional nozzle, for which two opposing, mutually parallel wedge-shaped surfaces are moved axially along the body of the rotor blade. Again, significant structural measures on the straightening rotor are required, which also leads to significant balancing problems due to the high centrifugal forces.
  • a straightener of the type mentioned is from the US 2 720 907 A known, in which an adjusting ring is rotatably mounted, which is axially displaced to the straightening wing on a rotation with an internal toothing on the housing meshing toothing of a sleeve connected to the adjusting ring.
  • the axial distances of straightening units are adjusted in the directional wing and adjusted via slide guides directional nozzles radially in the directional wing.
  • this straightener occur due to the axial displacements when adjusting the directional nozzles on the above already carried out balancing problems.
  • the present invention seeks to further develop such a straightening such that it can be used for particularly high speeds, wherein the balancing problems known in the prior art completely or at least largely accounts.
  • this is achieved in a straightener of the type mentioned above in that the adjusting ring is attached to the rotating straightening and connected to its own rotary drive, the position of the straightening of at least one straightening unit within the straightening blade by turning the adjusting ring is adjustable relative to the straightening.
  • the straightener according to the invention are for adjusting the radial position of the directional nozzle of the at least one straightening unit within the straightening no constructive measures used more comprising the elements which operate by axial displacement within the straightening wing, thereby the otherwise consequent considerable design effort as well as The risk of balancing problems occurring in such solutions is completely eliminated. Instead, an concentric with the rotation axis of the directional wing mounted adjusting ring is used, which leads to no balancing problems already by this arrangement, which also applies insofar as it causes the adjustment of the radial position of the directional nozzle in the directional wing only by a relative rotational movement to this.
  • the measure used according to the invention for the adjustment of the radial position of the directional nozzle within the directional wing on this concentrically mounted to use this rotatable adjusting, which must be rotated to adjust only relative to the directional wing, a remarkably simple measure that without considerable constructive Effort is feasible.
  • a concentric with the directional wing arranged adjusting ring with the fundamental advantage that no significant balancing problems are induced, not even with an adjustment of the directional nozzle during operation of the straightener leaves a clear distance to those in the known straighteners with straightening wings almost continuously recognize used, axially movable elements.
  • directional nozzle should in principle be understood to mean that all kinds of suitable straightening elements, such as (single or multi-part) straightening jaws, bushings, rollers o. ⁇ . Should be included equally.

  • the adjustment of the position of the directional nozzle of the straightening unit which is here formed by the adjusting itself within the straightening by a relative rotation of the adjusting to this, whereby the position of the directional nozzle to the non-adjustable positions of the directional nozzles of the adjacent straightening devices , At least the directional nozzles of the inlet part and outlet part, is changed.
  • the straightening a housing with a shoulder on which the adjusting ring is rotatably mounted, wherein the radial position of the straightening the at least one straightening unit via an intermediate gear through the adjusting ring during a rotational movement of the same relative to the straightening adjustable is.
  • the intermediate gear comprises a housing mounted on the shaft, parallel to the axis of rotation, which is at one end via a first gear engaged with an adjusting ring mounted on the internal teeth and meshes at its other end via a further, second gear with a rack, which the Directional nozzle, radially adjustable in their position, carries.
  • the structure of the intermediate gear in this embodiment by means of a rotary shaft provided at both ends with a gear wheel does not change its position within the directional wing even with an adjustment of the position of the directional nozzle, so that there could not be an additional balancing problem here as a result of an adjustment. Rather, this intermediate gear in the construction of the directional wing in terms of a possible imbalance can be fully compensated, without it then, even at high speed, with an adjustment during operation comes to an additional imbalance.
  • the housing is provided in one piece, preferably in the housing, axially adjacent the shoulder, a recess is formed, in which a bearing for supporting the shaft of the intermediate gear is mounted.

In this way, the adjustment of the attached in each straightening unit directional nozzle is possible in a very space-saving arrangement, although only two adjusting rings are used.
