Definitions

  • the invention relates to a roll stand with a device for the axial displacement of adjustable rolls according to the preamble of claim 1 and is thus based on DE-PS 24 40 495.
  • Roll stands of this type are designed for the opposite axial displacement of similar rolls, for example work rolls, intermediate rolls and / or back-up rolls, in order to be able to influence the rolled profile.
  • an axial displacement of the rollers is only useful from the point of view of uniformizing the roller wear.
  • the force transmission of a pair of hydraulic cylinder-piston units takes place on a chock of an axially displaceable roller via connecting members on outwardly projecting arms of the chock, in which the roller is not only supported but also axially secured and thus follows the axial displacement of the chock.
  • the device for the axial displacement of the roller is usually only provided on the operating side of the roll stand, since the drive-side chock of the roller easily follows each axial displacement.
  • each cylinder-piston unit Since the non-extendable part of each cylinder-piston unit is fixed to the side of a chock on a stand spar, but the roller with its chocks can be adjusted or changed in height to influence the thickness of the rolling stock, the outwardly projecting arms of the operator must Installation piece relative to the connecting links on the extendable parts of the cylinder-piston units to be movable in the vertical direction.
  • the outwardly projecting arms of the chock therefore have vertical strips, each of which is surrounded on both sides by counter strips of the connecting links with play.
  • the outer counter bar must be removable considering the axial expansion of a roller (DE-PS 33 31 055, Fig. 1). If the cylinder of a cylinder-piston unit is the extendable part, this cylinder can be provided on the chock side with an outer vertical surface with a vertical groove therein, into which an outwardly projecting locking bar of the chock engages. In this type of positive coupling between a height-adjustable chock and the extendable cylinder, the locking bar must be removable in its longitudinal direction to remove the roller (Fig. 3 of DE-PS 33 31 055).
  • the invention has for its object to release and restore the positive connection between a chock and an extendable part of a cylinder-piston unit of an axial displacement device from the need to do manual labor or to adjust any bolts to enable roll removal.
  • the coupling process for an upper roll or a roll of the upper set of rolls is carried out by an upward coupling stroke of the intermediate pieces by means of the pressure piston or pistons of the hydraulic bending device, whereas for a lower roll or a roll of the lower set of rolls the intermediate pieces are to be steered downwards from an elevated position .
  • the intermediate pieces remain in this position relative to the protruding parts, for example lateral claws of the chock which are provided with a coupling part (projection or recess). It is therefore recommended that the intermediate pieces can be controlled either upwards or downwards by the devices for balancing or counter-bending the roller assigned to them.
  • each cylinder-piston unit is expediently rigidly connected to an intermediate piece as a non-extendable part, the cylinder being displaceably and non-rotatably guided in the intermediate piece as an extendable part.
  • the cylinder receives a horizontal surface facing the protruding part of the chock into which a transverse groove is incorporated. In this transverse groove, a horizontal connecting bar on the chock side can be positively latched, specifically - as mentioned - for an upper roller by controlling an intermediate piece upwards and for a lower roller by controlling an intermediate piece downwards.
  • a thickened round shaft of its fixed piston rod serves to guide each cylinder, the non-rotatable securing of the cylinder being effected by its angular outer contour (claim 3).
  • the invention is explained with reference to the two axially displaceable work rolls 1 and 2, which are mounted in chocks 3 and 4 and axially secured, as shown in FIG. 3.
  • the chocks have cantilevered claws 3a, 4a and are supported on height-adjustable spacers 5 and 6.
  • These intermediate pieces are only fixed in a vertically movable manner on a column 7, as shown in FIG. 3.
  • These intermediate pieces 5, 6 lie between a two work rolls 1, 2 common pressure piston 8 of a hydraulic bending device which is driven in the lower intermediate piece 6 so that it can be acted upon twice, and the piston rod 8a of which is connected to the lower intermediate piece 5 in a tensile and compressive manner.
  • the spreading bending force exerted by the pressure piston 8 during the rolling is transmitted via the spacers 5, 6 and their flat pressure bars 9 extending over the length of the axial roller displacement to counter pressure bars 10 of the claws 3a, 4a, but with the interposition of elastic bars 11, absorb the tilting movements of the chocks 3, 4 due to roll deflections.
  • hydraulic piston-cylinder units 12 and 13 are supported by the superimposed intermediate pieces 5, 6 - following their height movements.
  • a fixed part of these units are pistons 14 which can be acted upon twice, the piston rods 15 of which, over a length 15a of reduced diameter, pass through and are clamped against a sleeve 16 with flange 17, which in turn are screwed onto the intermediate pieces 5, 6.
  • the sleeves 16 virtually form a round shaft of the piston rods 15 on which the movable part of the cylinder-piston units 12, 13, namely the two-part cylinders 18, 19, are axially guided.
  • the actual cylinder 18 forming the two pressure chambers for the fixed piston 14 of each unit 12, 13 is pot-shaped and provided with a cylinder cover 20 which is penetrated by the piston rod 15.
  • the cylinder part 18 is connected in a manner not shown to a guide part 19, the outer contour of which is an upstanding rectangle with an eccentric bore 21 for guidance on the sleeve 16. From the views in FIG. 1, left half of the drawing, and FIG. 3 it can be seen that the actual cylinder part 18 has a square configuration, the side length of which corresponds to the width of the outer rectangular guide part 19. Therefore, in Fig. 1, left half of the drawing, the protruding parts of the extension pieces 19, which have horizontal surface 19a facing the claws 3a, 4a, into each of which a transverse groove 22 is incorporated (FIG. 2).
  • a locking bar 23 engages in a form-fitting manner, which is screwed onto the laterally protruding claws 3a, 4a of the chocks.
  • This form-fitting coupling between one for axial displacement a roller extendable guide piece 19 and ultimately a chock 3 or 4 is maintained with each vertical position of the work rolls 1, 2 without relative movement, since the cylinder-piston units 12, 13 are carried by the vertically movable intermediate pieces 5, 6 and these due to the upcoming
  • the expanding bending force of the hydraulic bending device follows the movements of the chocks when the rollers are turned on.
  • the pressure space D (FIG. 2) is to be pressurized, as is known, in order to apply the spreading bending force for both work rolls 1, 2 or at least a force that keeps an upper intermediate piece 5 in contact with an upper chock 3.
  • the pressure chamber A is to be additionally pressurized in order to raise and lower the upper intermediate piece 6 to disengage the locking strips 23, which is why the piston rod 8a is also connected to the upper intermediate piece 5 in a tensile manner.
  • a stop (not shown) on the stand spar 7 determines the height of the intermediate pieces 5 and 6 in the position for changing the rollers. Conversely, a coupling process takes place after the re-installation of the rollers via the pressure chamber D, whereby the intermediate pieces 5, 6 are moved apart until the locking strips 23 enter their transverse grooves 22 at the same time and the intermediate pieces rest against their claw-side claws.
  • the invention can also be implemented for intermediate rolls or back-up rolls, but each intermediate piece must then be assigned one or at least its own pressure piston which is supported on a block which is fixed to the stand. Basically, it is not important within the scope of the invention to generate bending moments with the aid of the bending devices in the rollers, rather the bending devices serve primarily to couple and couple coupling parts by adjusting the height of the coupling parts relative to one another.
