Definitions

  • the invention relates to a device for the axial positioning displacement of roller bearing supports guided in stator windows of a stator pair of the stator of multi-roll stands with, in stator-fixed support frames, pivotable articulated guides about a horizontal axis lying transversely to the roll axis direction and sliding carriages guided in these, by lifting motors are drivable and have steering coupling devices for releasable connection of the sliding carriage with the roller bearing support assigned to it.
  • the Guides for the sliding carriages assigned to the roller bearing supports in a common support frame fixed to the stand, the frame plane of which is articulated parallel to the roller plane, and the coupling devices arranged on the sliding carriages consist of a clamping pliers mounted on the carriage transversely to the roller axis direction, the clamping ends of which are hook-shaped from both sides in corresponding Recesses can be introduced and removed in the roller bearing carrier.
  • This device builds relatively wide, since the inner opening width of the support frame must correspond to the width of the stator window, and it takes up the entire space behind the outer end face of the roller bearing supports outside of the stand, thereby hindering access to the roller bearing supports and the attachment of others for operation of these parts necessary equipment and units.
  • This known device can therefore be used on the operating side of a roll stand only for the axial displacement of certain groups of rolls in which such disabilities can be accepted.
  • the devices cannot be used on the drive side of the rollers, since the support frame guide and sliding carriage are located in the space required for the drive transmission elements of the roller.
  • the invention has for its object to improve the generic device so that it can be used with any desired roll group of a multi-roll stand, ie the work rolls, the intermediate rolls and possibly also the backup rolls. Regardless of whether the device is to be arranged on the operating or the drive side of the rollers.
  • both support frames together with their respective slide guides and their sliding carriages with steering Coupling are assigned to the same roller bearing bracket, it is achieved that the space behind the end faces of the roller bearing bracket, laterally outside of the roll stand for the operation of the stand, the installation of auxiliary operating devices, for. B. for the automatic operation of the roll stand or for the drive transmission elements of the rollers, for. B. articulated spindles is available.
  • the guide is mounted in a floating arrangement on a pivot axis seated in the support frame
  • the lifting motor of the sliding carriage consists of a piston-cylinder unit, the piston rod of which is pivot-mounted in the axis line of the pivot axis of the guide, and whose cylinder is radially connected to a guide sleeve of a round pin, together with a piston-cylinder unit on the piston rod of which the round pin is seated, forms the sliding carriage, the round pin being able to be inserted or removed from a cylinder recess in the facing side of the roller bearing carrier to be dispensed with, as is necessary in the known device, the coupling device with an additional, transverse to the roll axis direction steering bearing, since the rotatable in the roller bearing bracket this pivot bearing forms, with the result that the device can not only be structurally simpler, but also builds significantly shorter.
  • the support frame 2 which is designed in the form of a U-bracket, is fastened to the roller stand 1 with its U-legs 2a.
  • upper and lower guides 3 and 4 are articulated at a distance above one another and are pivotable about upper and lower axes 5 and 6.
  • the upper guide 3 hangs in the piston-cylinder unit 7 (shown in broken lines), which is articulated in a bearing 8 in the upper U-leg 2a of the support frame 2, and the lower guide 4 is provided by a piston-cylinder unit 10 supported, which is articulated in a bearing 9 in the lower U-leg 2a of the support frame 2.
  • a sliding carriage 11 or 12 see FIG.
  • the support frames 2 are arranged as a pair of support frames with frame planes running perpendicular to the roller plane, parallel to one another on the stand pair 1.
  • the Piston-cylinder units 7 and 10 are subjected to a pressure of a predetermined size, which remains essentially constant and which counterbalances the weight with respect to the dead weight of the guides 3, 4 and their sliding carriages 11, 12 and, if applicable, the weight components which result result in an additional load on the roller bearing supports 16 if these are arranged on the drive side.
  • This weight compensation is particularly important because it must be avoided that the other actuating forces applied to the rollers or the roller bearing supports, for example forces from roller bending devices, would be adversely affected by such weights.
  • the sliding carriage 11, 12 essentially consists of the piston-cylinder unit 14 on its piston rod 14a, which is seated in a coaxial guide sleeve 18, round bolts 15.
  • Radially attached to the guide sleeve 18 is the cylinder 13a of the piston-cylinder unit 13, the piston rod 13b of which is connected to a pressure nut 19 at right angles to the pivot axis 6 of the sliding carriage 11 or 12.
  • the box-shaped guide 4 or 3 is pivoted about the axis 6 in the support frame 2 and, due to the special design of the piston-cylinder unit 13 described as a sliding drive for the sliding carriage 12 or 11, represents a particularly short, compact actuator unit.
