Definitions

  • the present invention relates to a leveler for straightening Richtgut, in particular of bands and parts of metal.
  • a leveler has a machine frame and an upper and a lower leveling unit.
  • Such a straightening unit has a plurality of straightening rollers, which are mounted in bearing strips. The higher the demands on the straightening result with the aim of the evenness of the straightening material, the more straightening rollers are used.
  • straightening thin material more straightening rolls are usually used with a smaller diameter than when straightening thick material using straightening rolls with a large diameter.
  • the straightening rollers both the upper and the lower, are supported by support rollers.
  • the support rollers are arranged so that in each case two adjacent in the conveying direction of the straightening support rollers cooperate with a straightening roller (see also Fig. 1 described further below).
  • the present invention is therefore based on the object to avoid the above-mentioned disadvantages as far as possible and in particular to avoid the expression of significant Stützabrow on the leveling rolls.
  • the support rollers which are arranged on a common axis of rotation, mounted in at least one support roller block and slidably disposed therewith.
  • the at least one support roller block By displacing the at least one support roller block, the entire row of support rollers of a common axis of rotation can be displaced.
  • the displacement of the support rollers take place in predetermined stages.
  • the support rollers can be moved along its axis of rotation, for example, by the amount of its width, so that the new contact area between the support roller and straightening roller directly adjoins the previous contact area.
  • the spacers are formed differently long, wherein a displacement of the support rollers or support roller blocks can be done by exchanging a longer against a shorter spacer on one side and vice versa on the other side along the axis of rotation of the support rollers.
  • the spacers have suitable dimensions.
  • the difference of the long spacer and the short spacer substantially corresponds to the width of the support rollers. This creates a gradual shift
  • the spacers on a threaded pin which is screwed into a corresponding threaded hole in the bearing strips and releasable again.
  • Other connections of the spacers with the bearing strips and / or the Stützrollenböcken are also included in the present invention.
  • the displacement of the support rollers can also take place continuously.
  • this displacement takes place by means of a motor drive.
  • the motor drive may comprise a motor and a rotating shaft rotated by the motor with an external thread extending through a bore in the at least one support roller block and may provide the external thread in at least one internal thread provided in the bore is, intervene.
  • the motor drive may comprise a motor and a rod longitudinally movable by the motor, which engages the at least one support roller block and displaces this support roller block during longitudinal movement of the rod.
  • Fig. 1 shows schematically an upper and lower straightening unit of a straightening machine (not shown) with upper and lower straightening rollers and upper and lower support rollers;
  • Figure 2 is a schematic view of a first embodiment of the straightening machine according to the invention according to arrow A of Figure 1 but with cut Stützrollenböcken ..;
  • Fig. 3 is an analogous view of a straightening machine according to the invention for
  • FIG. 4 shows a partial sectional view of a straightening machine according to the invention after gradual displacement of the support rollers with their support roller blocks;

  • Fig. 6 shows a first alternative second embodiment of the invention
  • Fig. 7 shows a second alternative embodiment of the second embodiment of the present straightening machine (lower straightening unit only).
  • FIG. 1 an upper straightening unit 3 and a lower straightening unit 5 is shown schematically in side view and in a conventional manner.
  • the upper straightening unit 3 has upper straightening rollers 7, which are arranged according to so-called “Richtwalzenannon" 8 at a predetermined distance from each other.
  • the lower straightening unit 5 has lower straightening rollers 9, which are also arranged according to the same Richtwalzen annually 8 spaced from each other. As can be seen from Fig. 1, serve the upper and lower straightening rollers 7, 9 for straightening straightening 1 1, which is moved according to the conveying direction 13 between the upper straightening unit 3 and the lower straightening unit 5 therethrough.
  • the upper straightening rollers are arranged offset by half the leveling roller pitch to the lower straightening rollers.
  • the occurring during straightening high straightening forces that can lead to an adverse curvature of the straightening rollers 7, 9 are absorbed by upper support rollers 15 and lower support rollers 17 and thus avoids a curvature at least largely or completely.
  • the upper support rollers 15 and the lower support rollers 17 are larger than the upper and lower straightening rollers 7, 9.

  • short spacers 29 and on the opposite side in Fig. 2 right, long spacers 31 are disposed between the upper and lower Stitzrollenböcken 21 and 23.
  • FIG. 3 corresponds to the view of FIG. 2, except that support impressions 33 are shown on straightening rollers 7 and 9 caused by upper and lower support rollers 15 and 17.
  • Fig. 4 the inventive displacement of the upper and lower support rollers 15 and 17 relative to the position shown in FIG. 3 is shown.
  • the short spacers 29 have been substituted for the long spacers 21 and the long spacers 31 have been substituted for the short spacers.
