Definitions

  • the present invention relates to a device for Straightening of metallic material, with a plurality of zigzag arranged straightening rollers according to the preamble of Claim 1.
  • roller straighteners devices for straightening metallic goods using rollers or rolls, also known as “roll straighteners” have been known for decades.
  • such devices have a more or less large number of straightening rollers, which in usually arranged in a zigzag pattern and located in the upper and let lower straightening rollers split.
  • To drive the individual straightening rollers are usually transfer cases provided that are driven by at least one motor and the driving force mechanically coupled to the corresponding ones Forward straightening rollers.
  • straightening devices for heavy rolling stock e.g. B. from Sheet piling
  • grooved or railroad tracks are becoming few Straightening rollers, for example two upper and three lower ones Straightening rollers used
  • thinner metallic Well like thinner sheets, a significantly higher number of Straightening rolls, for example 17, 21 or more straightening rolls are provided.
  • the present invention is therefore based on the object a device for straightening metallic goods, with a plurality of straightening rollers arranged in a zigzag shape and to create at least one transfer case, which has a simple structure, and in which the harmful Effects of negative moments largely avoided become.
  • d. H. of a freewheel becomes one too proposed simple and easy-to-use constructive solution, which is also a robust construction of the straightening device enables. It can also be an extremely space-saving Construction can be achieved.
  • both can alternatively also on some A directional switch on all drive trains with negative moments Coupling should be provided so that the occurrence the negative moments have a reduced negative impact on the drive.
  • Output strands with negative moments at least partially are divided into groups and the drivetrains each Group are mechanically coupled to a distributor wheel and at least one distributor wheel with a directional switch Coupling is provided.
  • a transfer case 30 is shown schematically.
  • the transfer case 30 serves to drive FIG. 17 Straightening rolls, a straightening roll device (not shown), as is known to the average person skilled in the art.
  • the 17 straightening rollers are driven by appropriate drive shafts with pinions 1 to 17 connected.
  • the transfer case 30 has in a housing 32 in the example three distributor wheels 20, 21 and 22 on the are rotatably mounted on axes 23, 24 and 25. All three Axes 23, 24, 25 are with corresponding teeth for mutual Engagement trained.
  • a motor (not shown) drives the drive pinion on the drive side 18, which in turn is a meshing drive pinion 19 drives. This interferes with the Distributor wheel 20, the one hand the distributor wheel 21 in meshing engagement drives and on its axis of rotation 23 also the output pinion 2 with the associated drive shaft for the drive the associated straightening roller sits.
  • the output pinion 2 meshes with it the output pinion 1, the output pinion 3 and the output pinion 5 of the corresponding straightening rollers and the driven pinion 5 also meshes with the output pinion 4 of the assigned Straightening roller.
  • Form the output pinion 1 to 5 a first group of output pinions, which over the distributor wheel 20 are driven.
  • the output pinion 9 of the associated straightening roller is in turn with the distributor wheel 21 rotatably on its axis 24 is arranged and is in engagement with the output pinions 6, 8 and 10 of the associated straightening rollers and the driven pinion 6 is in engagement with the output pinion 7 and the drive pinion 10 is in engagement with the driven pinion 11.
  • the output pinions 6 to 11 form a second Group together with the distributor wheel 21.
  • the output pinion 14 is in connection with the distributor wheel 22 and is arranged on its axis of rotation 25.
  • the Output pinion 14 is in meshing engagement with the output pinions 13, 15 and 17, the output pinion 13 in Engagement with the output gear 12 and the output gear 17 is in engagement with the output pinion 16. Form with it the output pinions 12 to 17 together with the distributor wheel 22 a third output group.
  • the feed direction of the metallic good to be straightened takes place according to arrow 36, i. that is, the first straightening roller is the one through the driven pinion 1 is driven, which is the numbering of the corresponding Connect additional straightening rollers in a zigzag shape. It follows that the output pinion 1, 3, 5, 7, 9, 11, 13, 15 and 17 of either the upper or the lower Belong to the group of straightening rollers or the output pinion 2, 4, 6, 8, 10, 12, 14 and 16 of either the bottom or the belong to the upper group of straightening rollers.
  • FIG 2 is a schematic sectional view along the line A-A of Figure 1, the transfer case 30 shown.
  • the Output pinion 1, 2, 5, 6, 9, 10, 13, 14, 17 are on corresponding Pinion shafts 51, 52, 55, 56, 59, 60, 63, 64, 67 rotatably supported, the pinion shafts in turn by means of corresponding bearing 70 are rotatably mounted.
  • the output pinions 3, 4, not shown in FIG. 7, 8, 11, 12, 15, 16 have corresponding pinion shafts.
  • the present invention thus becomes particularly advantageous minimized drive torques, since the compensation that occurs with conventional straightening roller drives the negative torques through increased, positive Torques are greatly reduced or even avoided. This leads to a significantly reduced drive power required, which is not only a correspondingly lower Dimensioning of the drive units but also too a correspondingly cheaper mode of operation Straightener leads. Or vice versa with the present Invention with the same drive power more guide power be achieved.
