Definitions

  • the present invention relates to a device for Straightening metallic material, with a majority of zigzags arranged straightening rollers.
  • roller straightening machines devices for straightening metallic material by rolling or rollers, also known as “roller straightening machines” have been known for decades.
  • such devices have a more or less large number of straightening rollers on in are usually arranged in a zigzag shape and upper and divide lower straightening rollers.
  • transfer cases To drive the individual leveling rolls are usually transfer cases provided, which 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 eg. B. from Sheet pile iron
  • grooved or railroad tracks are few Straightening rolls, for example, two upper and three lower Straightening rolls used, whereas with thinner metallic Good, as thinner sheets a considerably higher number of Straightening rolls, for example 17, 21 or more straightening rolls are provided.
  • rollers or rollers on which the straightening material is bent the most are able to draw more straightening material into the straightening machine than the other rollers can continue to transport with the same diameter and the same speed.
  • the straightening material is then pushed over these rollers with negative slip and exits at a speed from the straightening machine, which is greater than the peripheral speed D / 2 ⁇ of the rollers.
  • the present invention is therefore based on the object a device for straightening metallic material, with a plurality of zigzag arranged straightening rollers and at least one transfer case, which has a simple structure, and in which the harmful As far as possible avoided the effects of negative moments become.
  • At least one directional clutch is provided in the range of negative moments that the Emergence of negative moments reduced or completely prevented is achieved that the adversely occurring negative Slip essentially or completely avoided can.
  • some of them may alternatively be used on all output lines with negative moments a directional switched Coupling be provided so that the occurrence the negative moments have a reduced negative impact on the drive.
  • the invention is characterized Straightening device characterized in that in the area negative moments at least one decoupling device is provided, the occurrence of negative moments the Connection of the respective output strands with the transfer case separates.
  • the controller this separation by an externally influenced regulation respectively.
  • a transfer case 30 is shown schematically.
  • the transfer case 30 serves to drive 17 Straightening rollers, a straightening roller device (not shown), as known to those of ordinary skill in the art.
  • the 17 straightening rollers are via corresponding cardan shafts with output sprockets 1 to 17 connected.
  • the transfer case 30 has in a case 32 in the example case three distributor wheels 20, 21 and 22, the are rotatably mounted on axles 23, 24 and 25. All three Axes 23, 24, 25 are with corresponding serrations for mutual Intervention formed.
  • a motor (not shown) drives the drive pinion on the drive side 18, which in turn has a meshing drive pinion 19 drives. This is in engagement with the Distributor 20, on the one hand the distributor wheel 21 in tooth engagement drives and on the axis of rotation 23 and the output pinion 2 with the associated PTO shaft to the drive the associated straightening roller sits.
  • the output pinion 9 of the associated straightening roller is in turn with the distributor wheel 21 rotates on the axis thereof 24 arranged and is in engagement with the output pinions 6, 8 and 10 of the associated straightening rollers and the output pinion 6 is in engagement with the output pinion 7 and the drive pinion 10 is engaged with the output pinion 11.
  • the output pinion 6 to 11 form a second Group together with the distributor wheel 21.
  • the output pinion 14 is in communication with the distributor wheel 22 and is arranged on the axis of rotation 25.
  • the Output pinion 14 is in meshing engagement with the output pinions 13, 15 and 17, wherein the output pinion 13 in Engagement with the output gear 12 and the output pinion 17 in engagement with the output gear 16 is. To form this the output pinion 12 to 17 together with the distributor 22 a third output group.
  • the feed direction of the metallic material to be straightened (not shown) is carried out according to arrow 36, d. h. that the first straightening roller is the one through the output pinion 1 is driven, what the numbering of the corresponding connect further straightening rollers in a zigzag shape. It follows that the output pinion 1, 3, 5, 7, 9, 11, 13, 15 and 17 either the upper or the lower Belonging group of straightening rollers or the output pinion 2, 4, 6, 8, 10, 12, 14 and 16 either the lower or the belonging 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 mounted, the Ritzeiwellen turn by means of corresponding bearing 70 are rotatably mounted.
  • the output pinion 3, 4, not shown in the figure 2, 7, 8, 11, 12, 15, 16 have corresponding pinion shafts.
  • the present invention is not limited to that shown Embodiment limited. So, for example between the pinion shafts and straightening rollers Be provided with facilities that transmit a negative Avoid moments on the pinion shafts. About that In addition, these facilities can be regulated from the outside, so that an all-encompassing and externally adjustable mode of operation the transfer case is made possible.
