Definitions

  • This invention relates to a multi-roll stand with two positively driven backing rolls, and two working rolls frictionally driven by the backing rolls.
  • the object of the present invention is to provide a device for roll-body correction, by means of which the roll profile can be accurately and quickly altered during the rolling operation.
  • an adjusting device is provided for the variable changing, in the direction of a deflection, of the lateral distance of the individual supporting rollers from the common axial plane of the backing rolls.
  • the height of the roll gap is varied symmetrically about the center of the path of rolling contact, over the breadth of the roll, so that as the rolled stock passes through, the most advantageous distribunied States atent tion of pressure for obtaining a rectangular cross-section of rolled stock is attained.
  • a particularly simple embodiment of the invention described is suitable for roll stands up to a breadth limited by the magnitude of the forces occurring.
  • wedge-pieces are already arranged between the bearings of the supporting rollers and the supporting bridges. These, however, serve the purpose of an axially parallel adjusting of the supporting rollers during the stoppage, and not of a change in the lateral distance in the direction of a deflection, for the correction of camber during the rolling operation.
  • wedges differing in the wedge angle are so arranged that those with the greatest angle bear in the middle of the supporting bridge, and with these are associated on both sides, wedges of a progressively diminishing angle, with the wedges being connected with piston-rods or, which are supported upon an eccentric shaft rockable by hydraulic means by way of a lever.
  • the actuation of the shifting cylinder thus yields, symmetrically about the center of the rolling path, the adjusting travels requisite for the desired deflection of the working rolls.
  • FIG. 2 is a view in vertical section, in two related planes AB and C-D of FIG. 1, through the roll stand;
  • FIG. 2a shows the roll stand in end elevation, looking in the direction of the arrow 2a in FIG. 2;
  • FIG. 3 is a view in vertical section through a roll stand with adjusting wedges
  • FIG. 4 is a view looking at FIG. 3 in the direction towards a row of wedges bearing on the supporting bridge with their adjusting means.
  • Two working rolls 1, 1' of a multi-roll stand are supported vertically against backing and driving rolls 3, 3' journalled in chocks 2, 2, with the axes of the working rolls being displaced from the vertical plane of the axes of the backing rolls.
  • the working rolls are supported by intermediate rolls 4, 4', 5, 5' on supporting rollers 6, 6, which are journalled in combs 7, 7 bearing horizontally on supporting bridges 10, 10 connecting the housings 8, 9.
  • the combs 7, 7' have a bearing contact on beams 11, 11' which extend parallel to the rolls and are anchored to the chocks 2, 2.
  • pressure-fluid cylinder-piston units 12 Between the upper and lower combs 7 and 7 are arranged pressure-fluid cylinder-piston units 12, which hold the same against their contact surfaces.
  • the hoods 20 do not extend over the entire breadth of the supporting bridge 10, but are provided only in the region of the cylinders 19.
  • the hoods 20 are therefore only slightly influenced by the bending of the supporting bridges.
  • the piston 18, by way of the lever 16 adjusts the tension rod 15 by imparting rotation thereto, whereby the latter draws the shackles 13 of the supporting bridges 10, 10" towards one another, and thus deflects the supporting bridges 10, 10.
  • This deflection is transmitted, by way of the supporting rollers 6, 6 and the intermediate rolls 4, 4, 5, 5 to the working rolls 1, 1.
  • the supporting bridges 10, 10" are provided, at the roller side, with notches 21. By the notches 21 the cross section of the supporting bridges 10' and 10' at the positions in question is reduced. By such notches the bending characteristic of the supporting bridge can be fixed to correspond to the requirements.
  • the intermediate rolls 4, 4' are journalled in rockable arms 22, 22, in which also the intermediate rolls 5, 5 are journalled in a slide block 23 slidable therein.
  • the arms 22, 22' are arranged compressed-air cylinders 24, in which, at the rear side, supporting forks 25 constituting pistons which serve for centering the bearings of the working rolls to the axial plane of the intermediate rolls 4, 4', 5, 5' are displaceable.
  • the upper arms 22 are secured by tension springs 26 to the upper chocks 2, so that even when the supporting rollers 6 are being dismantled, the intermediate rolls 4 bear against the upper backing roll.
  • a cylinder 3-7 having a piston rod 38 anchored to the chock 2.
  • the slide-piece, together with the claw is drawn back, whereby the dismantling of the working rolls 1, 1 is rendered possible.
  • pressure-fluid cylinder-piston units 39 which support the upper arms 22, and prevent the intermediate rolls 4, 5 from falling down when the working rolls 1, 1' are dismantled.
  • the position of two outer adjusting wedges 53 is variable by means of intervening layers 54 and can be fixed by means of screws 55, in order to straighten the supporting rollers 44 with their axis parallel during stoppage.
  • the inner adjusting wedges 51 are connected with piston-rods or connecting-rods 56, which are accommodated upon an eccentric shaft 57, which is journalled upon the supporting bridge 49.
  • piston-rods or connecting-rods 56 which are accommodated upon an eccentric shaft 57, which is journalled upon the supporting bridge 49.
  • levers 58 Upon the eccentric shaft are anchored levers 58, which are connected with hydraulic cylinders 59 having piston-rods 60 thereof pivoted to the supporting bridge 49.
  • the two inner ones have a greater inclination than the outer ones.
  • the ditfering inclinations of the wedges have the result that when pressure fluid is supplied to the cylinders 59, their contact surfaces designed for the bearing plates 45 extend in an arc.
  • a Inulti-roll stand comprising: roll housings, deflectable supporting bridges connecting the roll housings, two positively driven backing rolls, two working rolls frictionally driven by the backing rolls, the axes of the working rolls being displaced from the vertical plane containing the axes of the backing rolls for the horizontal supporting of the working rolls, supporting rollers journalled in the deflectable supporting bridges, intermediate rolls interposed between the working rolls and the supporting rollers to aflord horizontal support to the working rolls, means for adjusting the lateral distance of the individual supporting rollers from the plane containing the axes of the backing rolls, shackles by which the supporting bridges bear on the roll housings, tension rods accommodated in the shackles, internally screw-threaded sleeves provided in the shackles, tension rods having external right and left-hand threads at the ends thereof accommodated in the said sleeves, adjusting cylinders, pistons slidable in the adjusting cylinders, and levers secured upon the tension rods connecting the tension rods with the pistons operative upon
