Definitions

  • the invention relates to a roller train with the features according to the preambles of claims 1 + 2; see for example EP-A 0 154 249.
  • Rolling mills according to the invention have the advantage that, in each embodiment, all rear stands, that is to say the drive-side stands, can remain on the machine bed when the rolls are changed in dimension. This simplifies the construction.
  • the roller axes or the centering bolts are tensioned or relaxed in a simple manner by hand using a Allen key.
  • the hydraulic bracing results in high concentricity.
  • all front stands since they are combined into one unit, can be lifted upwards, so that no space need be available for the removal on the front side. It is not necessary to loosen screw connections when changing.
  • the frictional connection of the front and rear stands results in great smoothness. Keyways in the roller axes are not required.
  • the operator-side that is, the front stand can also remain stationary. All you need is a magazine stand for each roll stand or a magazine stand for all roll stands.
  • the magazine stand picks up the newly installed rollers. It also serves to store the same. If the replacement of the rollers by means of a magazine stand is provided, then the pushing distance of the rear stands must be so large that the space required for inserting the magazine stand is available.
  • roller axles 01 are not fixed in the rear stand 02 but in the front stand 03 (operating side). All front stands 03 are permanently mounted on a common removable plate 04.
  • the torque is transmitted to the respective roller 07 and the cardan shaft 06 or individual drive 08 via hydraulic tensioning elements 09, which are integrated in the roller axis 01 and are acted upon together.
  • the axis or bore tolerances are dimensioned such that a sliding seat ensures that the rollers 07 are easily pushed on.
  • the clamping force is introduced by actuating a clamping screw 11 with pistons 12 which act on hydraulic clamping elements 09.
  • the hydraulic tension ensures an absolutely centered fit of the rollers.
  • the concentricity reaches top values. Stands 02 and 03 are also given additional stability due to the frictional connection of the roller axes, which has a positive effect on the smooth running of the system.
  • the interchangeable plate 04 on which all the front stands 03 are jointly attached, is placed on the machine bed 05, centered by bolts 13 and hydraulically clamped as described. It is actuated by clamping screws 19. Only two clamping bolts 13 are required.
  • the upper roller axes 01 and the associated lower roller axis move apart in a stand by means of a spindle gear 16, for which manual actuation 14 or a servo motor 15 is provided, into an end position, which is identified by 17 in FIG. 2.
  • the hydraulic systems in the roller axes are then relaxed via tensioning screws 11.
  • the non-positive connection is interrupted.
  • the rear stands 02 travel together to the side by means of a pushing device 18 (hydraulic cylinder), as shown in FIG. 2, so that the roller axles 01 come out of the bearing bushes 20 of the rear stands 02. As shown in FIG. 2, all front stands 03 are then free.
  • the connection of the exchangeable plate 04 to the machine bed 05 is released.
  • the removable plate can then with all front stands 03, on which the Roller axes and the rollers are removed and replaced with a prepared new stand set with new rollers.
  • the installation of the new stand set, the ready-to-use setting of the entire roller mill takes place in reverse order.
  • the removable plate is put on and clamped.
  • the rear stands then move together until the roller axles 01 are received by the bearing bushes 20. Then the rollers and bearings are braced hydraulically.
  • the rolling stand shown in FIG. 5 also has a front stand 30 and a rear stand 32. Both stands are equipped with spindle drives 30a.
  • Fig. 5 shows the roll stand in its position when changing the dimensions of the rolls.
  • the two roller axes 31 of the front stand are free.
  • the rear stand 32 is moved to the side, so that there is a space between the two stands which is so large that there is an additional space between the free roller axles 31 and the rear stand 32.
  • a magazine stand 40 is used for the change of dimensions, which carries the two new rollers 44 to be applied.
  • the magazine stand 40 has a horizontal leg 42 which is slidably seated on a track 45 of the machine bed.
  • two hollow mandrels 43 are held above, the interior of which has the same dimensions as the bearing bushes 34 installed in the rear stand 32.
  • the new rollers 44 are each slidably seated on a hollow mandrel 43. In the position shown, the roller axes are 31, bearing bushes 34 set with the same axis. From the position shown, the magazine stand 40 with the new rollers using the Pushing device 35 pushed in the direction of the arrow to the left against the front stand 30 into the position 40a shown in broken lines, where the sections 31b of the roller axes intended for storage are received by the two hollow mandrels 43. From this position, the new rollers 44 can be pushed on the sections 31a of the roller axes intended for their storage by hand.
  • the magazine stand can be pushed back into the space and lifted off with a crane.
  • the rear stand 32 is displaced against the front stand until the axle sections 31b of the roller axles are received by the bearing bushes 34.
  • the hydraulic bracing of the rollers or the bearings can then be carried out as described.
  • the magazine stand can be dimensioned so that it carries two rollers for a roll stand. But you can also provide magazine stands that carry several pairs of rollers for several stands.
  • the rear stands 32 can alternatively also be fixed and the front stands 30 can be displaced.
