Definitions

  • the invention relates to a four-roll stand according to the preamble of the claim 1 and a six-roll stand according to the preamble of claim 2 as well as a method for the optional operation of the four- or six-roll stand with thin and thicker work rolls in diameter.
  • One or more roll stands can be found in a rolling mill.
  • the rolling stock is gripped by the work rolls, which are in the rolling direction turn against each other. It is due to the roll rotation of the work rolls moved forward. In the roll gap, the thickness of the rolling stock is determined by the high Pressure applied by the work rolls is reduced.
  • a four-roll stand (Quarto) has two work and two backup rolls.
  • a six-roll stand (Sexto) has two work rolls, two backup rolls and between the work rolls and intermediate rolls arranged on the support rolls.
  • the work rolls themselves have no drive, but are at best connected to each other by means of a synchronized gearbox to a possible Avoid slippage of the work rolls.
  • a quick conversion of these roll stands on thicker work rolls is neither intended nor possible because the exclusive drive of the backup rolls and the entrainment of the work rolls is not possible due to friction with thicker work rolls.
  • JP-A-62-197207 discloses a six-roll stand, where the upper and lower intermediate roll and the upper work roll are driven by spindles.
  • the engines provided to drive the spindles individually or coupled. This will be done in one Corresponding adjustment options by positioning gear wheels performed. According to this invention there is also the possibility uncouple individual spindles. A conversion of this device to thicker work rolls is not provided, however, because the exclusive drive from both work rolls not possible. A corresponding spindle was not considered.
  • the invention is therefore based on the object to propose a roll stand that allows rapid adaptation to rolling stock different strength and / or hardness allowed.
  • the invention proposes that the Back-up rolls and work rolls or intermediate rolls that can be driven via drive spindles and work rolls or back-up rolls and intermediate rolls, respectively a detachable device is assigned, which is connected to a motor.
  • This combined drive according to the invention in the four-roll or Six-roll stand allows thick work rolls to be assigned to them detachable device to connect directly to a motor, while at Use of thinner work rolls in a four-roll stand two back-up rolls, which in this case have detachable devices connected to the engine.
  • the thin work rolls are then only carried by friction from the backup rollers. Be consistent with a six-roll stand to operate the thin work rolls only the back-up rolls and / or the intermediate rolls over those assigned to them detachable devices connected to the engine while operating the thicker work rolls only the work rolls over the assigned to them detachable devices are connected to a motor.
  • roller there is a connection between the roller and the motor only then when a direct flow of force from the roller over the spindle, the releasable Device and, if necessary, an intermediate gearbox to the engine consists.
  • a roller has no connection to the motor in the sense of this definition, which is only taken over by friction from another driven roller becomes.
  • the roll stands can also be designed so that as a detachable device the hits of the drive spindles of the work rolls work themselves if these are removed from the drive pins of the work rolls. Therefor the drive spindles can telescopically enable these trigger movements be executed.
  • the thin work rolls have no drive pins and consequently the hits of the Drive spindles become ineffective. That too is that of the thin work roll assigned hits of the drive spindle released from the work roll. The drive spindles for the work rolls then run loose.
  • a uniform and cost-effective drive of all rollers can be achieved if the support and work and, if necessary, intermediate rolls of a common motor via a gear, especially via a worm gear are driven.
  • a gear especially via a worm gear
  • Adjustment devices such as step wedges on the top of the scaffold and the underside of the scaffold.
  • Thin work rolls preferably come in the roll stands according to the invention with a low-wear material, especially powder metallurgical Work rolls (high-strength HSS rolls) are used. These work rolls can, for example, according to the HIP (Hot Isostatic Pressing) process getting produced.
  • HIP Hot Isostatic Pressing
  • the worm gear 6 consists of the two middle work roll gear wheels 8, 9 and an upper and a lower Back-up roller gear 11, 12.
  • Both the support rolls 1, 2 and the work rolls 4, 5 are drive spindles, respectively 13,14,15,16 assigned to the via the worm gear 6 are connected to the motor 7.
  • the associated with the support rollers 1 and 2 Drive spindles 13, 16 each have a clutch 17, 18, which in disengaged state the flow of force between the support rollers 1, 2 and Interrupt motor 7.
  • the thin work rolls 4, 5 shown in FIG Clutches 17, 18 engaged only to drive the support rollers 1, 2, while the drive spindles assigned to the thin work rolls 4, 5 14, 15 run loose.
  • the work rolls 4, 5 shown in FIG. 1 have no drive pins the flow of force between the thin work rolls 4, 5 and the motor 7 is interrupted.
  • the four-roll stand according to FIG. 2 differs of that according to Figure 1 in that the two support rollers 1, 2 immediately above their drive spindles 13, 16 connected to a separate backup roller motor 26, 27 are. However, this difference is meaningless for the way it works.
  • the thicker work rolls 24, 25 now have drive pins 28, 29, which with the hits 19, 21 of the drive spindles 14, 15 cooperate.
  • the adhesion of the thicker work rolls 24, 25 is thus over the spindles 14, 15 and the pinion gear 6 to the motor 7, which in this embodiment only drives the work rolls 24.25.
  • the clutches 17, 18 of the drive spindles 13, 16 for the support rollers 1, 2 are disengaged so that the support rollers 1, 2 run ineffectively while the backup roller motors 26, 27 are switched off.
  • All drive spindles are in a manner known per se as cardan shafts trained to fix the offset to the gear or motor side compensate the arranged attachment points of the drive spindles.
  • the invention allows rapid adaptation to rolling stock of different types Strength and / or hardness by using the rolling stands with little effort optionally operated with both thin and thicker work rolls can be.
  • the combined drive proposed according to the invention for this purpose in the four-roll or six-roll stand allows thick work rolls connect directly to a motor while thin work rolls only carried by friction from adjacent support or intermediate rollers become.
