  • the invention also relates to a straightening roller arrangement with two straightening rollers arranged one above the other, which form a curved straightening gap.
  • the invention also relates to a two-roll straightening machine and a method for straightening rotationally symmetrical workpieces to a longitudinal axis.
  • straightening machines with straightening rollers are known for rotationally symmetrical workpieces on a longitudinal axis, which are arranged on rigid, perpendicular to the continuous workpieces arranged behind one another and one above the other and bend the workpiece to be straightened in the required manner.
  • straightening rotors are known in which leveling rolls or directional nozzles are arranged on axes, which in turn rotate about the workpiece.
  • the object of the invention is achieved by a rotating about a roll axis, for straightening to a longitudinal axis rotationally symmetrical workpieces certain straightening roller with a straightening along the straightening roll axis straightening surface, which is defined by a correspondingly curved generatrix, wherein the straightening roller is characterized in that the Generating has at least one turning point.
  • a turning point is to be distinguished from a maximum or minimum of the generators, as this itself from the prior art, for example from the DE 23 57 570 A1 is known and what ultimately only a single direction of curvature of the corresponding roll surface, be it now on the one hand convex, bulbous, convex or convex or on the other hand domed or concave inside.
  • the direction of curvature changes, so that usually both a minimum and a maximum can be found and the roller itself may well have a convex and a concave surface area.
  • the straightening roller can advantageously be designed with a corrugated profile, whereby in particular thinner or high-strength materials can be directed exceptionally favorably.
  • a substantially greater deflection of the workpiece or wire to be straightened with a smaller straightening roller length and a mean straightening roller diameter can be achieved particularly well with a straightening roller contour selected in this way.
  • a corresponding increase in performance can be achieved although predetermined roll dimensions are met or exceeded, so that even existing roll levelers can be equipped with the present straightening roll and operated with increased directivity advantageous.
  • straightening roller means any rotating cylindrical device along which an elongate, rotationally symmetric workpiece can be guided in a directional direction.
  • each of the straightening surface of a straightening roller is defined by a generatrix, which is guided around the straightening roller axis of the straightening roller around.
  • a particularly preferred embodiment provides that the generator has at least two inflection points. Because of at least two such inflection points, both an entry angle and an exit angle on a straightening roller pair can advantageously be reduced in a particularly far-reaching manner with respect to a workpiece or wire to be straightened for the same or ideally greater maximum deflection of the workpiece or wire to be straightened.
  • the object of the invention is also achieved by a straightening roller arrangement with two straightening rollers arranged one above the other, in which according to the invention at least one straightening roller according to one of the features described here, in particular according to one of the features described above, is configured.
  • At least one of the two straightening rolls of the straightening roller arrangement has a generatrix with at least one point of inflection, it is possible, in particular, to advantageously direct very thin wires.
  • both straightening rollers of the straightening roller arrangement are designed as straightening rollers according to the invention according to one of the features described herein.
  • the memory effect of the respective material can be eliminated in this case particularly successfully.
  • the present straightening roller arrangement can be used particularly advantageously in a manner known per se so that pinching limits with respect to the straightening rollers can advantageously be shifted in a manner known per se.
  • the term "main passage direction" here refers essentially to the main transport direction of the workpiece in the direction of its longitudinal axis through the straightening roller arrangement.
  • the object of the invention is achieved by a straightening roller arrangement intended for straightening workpieces that are rotationally symmetrical with respect to a longitudinal axis with two straightening rollers arranged one above the other and forming a straightening gap with a directional triangle, wherein the straightening gap comprises at least two straightening triangles having.
  • the straightening gap comprises at least two straightening triangles having.
  • the inlet and outlet angles can be approximated to the straightening roller assembly, which advantageously largely on a height adjustment, possibly completely, can be dispensed with, which almost always must be made at different workpiece diameters or different straightening rolls to to achieve a required directional precision.
  • a further solution to the object of the present invention proposes a two-roll straightening machine with a straightening roller arrangement according to one of the features explained here.
  • a two-roll straightening machine can be built exceptionally compact with high straightening performance, since in particular can be dispensed with a height adjustment for straightening rollers.
  • the present two-roll straightening machine comprises in a known manner both an inlet guide and an outlet guide for workpieces.
  • guides are not directly involved in the actual bending process. However, they are so crucial that the workpieces have to be guided at a predetermined height to the straightening rollers or must be performed accordingly by the straightening rollers. Inadequate guidance of the workpieces could in the worst case, the straightening quality of the workpieces be adversely affected.
  • the invention proposes as a solution to the object presented a method for straightening rotationally symmetrical to a longitudinal axis workpieces, which is characterized in that the workpiece by one of two Guiding gap formed above the straightening rollers is guided and guided this straightening gap in the axial direction at least by two differently curved areas.
  • the term "one above the other" in the present context does not necessarily mean a vertical arrangement of both rolls, but it is sufficient if the two rolls are arranged opposite each other and can form a corresponding aiming gap.
  • the handle since in particular of the handle relatively simple, but is a vertical superimposition of the two rolls.
  • the in the FIG. 1 Straightening roller assembly 1 shown comprises an upper straightening roller 2 and a lower straightening roller 3, each about a straightening roller axis 4 and 5 in a related straightening roller 6 and 7 in a machine frame 8 of a two-roll straightening machine 9 (see in particular FIG. 3 ) are stored.
  • the machine frame 8 comprises an upper part 10 and a lower part 11, which are connected to each other by tie rods 12 (numbered here only by way of example).
  • the upper straightening roller frame 6 is on the underside of the upper part 10 and the lower straightening roller frame 7 is rotatably mounted on the upper side on the lower part 11 each about a horizontal axis of rotation 13. This allows an angle adjustment (see also FIG. 2 ) of the two straightening rollers 2 and 3 with respect to a main machine direction 14, which in the present case essentially coincides with the main passage direction 15 of a workpiece 16 to be straightened along its longitudinal axis 17.
  • the upper straightening roll 2 are set at an angle ⁇ (indicated here by the reference numeral 18) and the lower straightening roll 3 at an angle ⁇ (designated here by the reference numeral 19) relative to the main machine direction 14 about the horizontal axis of rotation 13.
