Definitions

  • the invention relates to a stand for rolling or roll casting of metals and non-metallic materials, with a first, fixed support and a second, adjustable for changing a roll gap bearing housing, which housing the bearings of the rollers and from the outer area of which itself facing end faces recesses are provided for receiving the adjusting device for the roll gap.
  • the conventional way of setting a roll gap is to clamp the rolls onto the plates on the one hand or to position the rolls via a spindle or a hydraulic cylinder, clamped in a roll stand.
  • the expansion of the roll stand always affects the roll gap, which leads to increased inaccuracy.
  • Driving on solid plates offers no possibility of adjusting the roll gap during operation.
  • DE-OS 26 46 388 shows a strand guide on a casting plant with mutually opposite frame or scaffold parts connected by tie rods, in which the strand guide rollers are mounted.
  • the casting gap ie the distance between two casting rolls, is changed by inserting spacer plates and determining the distance between the bearing housings from each other. Calibrated plates are necessary for precise adjustment, which are based on the different chocks are matched. The fine adjustments usually have to be made with thin gauges. A correction of the casting gap during the operation of the casting system is completely impossible.
  • DE-OS 32 38 938 discloses a device for adjusting a gap formed by two rolls, in particular a casting gap of a roll caster for producing aluminum strips.
  • the rollers are arranged in roller bearings surrounded by bearing housings.
  • At least one of the bearing housings has, at its corner regions opposite the other bearing housing, in each case inclined surfaces at a certain angle with respect to an axis, which wedge surfaces of movable adjusting blocks bear against them. The wedges can therefore be moved in the direction vertical to the roller axes.
  • the inventor has set itself the task of creating a stand for rolling or roll casting of the type mentioned, which allows a further simplified adjustment of the roll gap for all types of stands, at least maintains the stability and with appropriately designed stands options for using electronic control and Control creates.
  • the object is achieved in that means for pivoting the second bearing housing about an axis of rotation running parallel to the axes of the rollers are arranged in the opposite recesses, means for adjusting the distance between the bearing housings and thus the roller gap are arranged in the other opposite recesses .
  • the distance between the bearing housing and thus the rollers is therefore not changed by parallel displacement of the second or upper bearing housing, but rather by its adjustable pivoting about an axis of rotation.
  • the bearing housings with the means according to the invention for adjusting the roll gap can be used in stands of all known embodiments, for example in closed stands or in stands for opening, which can also have prestressing devices.
  • Scaffolds according to DE-OS 32 38 936, which are described there for strip casting machines, have proven to be particularly advantageous. This scaffolding works according to the pretensioning principle, but with a column-less system.
  • the means for pivoting the second bearing housing about an axis of rotation parallel to the axes of the rollers are preferably configured as follows: - At least one hinge, formed from a fork, a tongue and a removable bolt mounted therein. - At least two nested cylindrical or at least two spherical slide bearings arranged on both sides, one inside the other.
  • the means for changing the spacing of the bearing housings correspond essentially to known means which have hitherto been provided on both sides of the end faces of the bearing housings.
  • interchangeable spacer plates are arranged in the corresponding cutouts, preferably corner cutouts. These plates must be slightly cambered at least on one side, because due to the different swivel positions not always a full surface Edition can arise.
  • Interchangeable gauge plates can be added for fine adjustment. Both spacer plates and gauge plates are precisely calibrated.
  • the means for changing the distance between the bearing housings, the spacer plates and / or gauge plates cannot be exchanged under load, so automated operation is not an option here.
  • non-prestressed scaffolding can also be equipped or retrofitted; however, these have the disadvantages mentioned with regard to the expansion under the action of force.
  • the means for changing the distance between the bearing housings with respect to the axis of rotation of the second bearing housings can be tangential spindles which can be rotated by hand or by machine.
  • the means for changing the distance between the bearing housings are designed as a hydraulic electronic nip control system. Like the spindle mentioned above, this can be operated automatically.
  • a hydraulic electronic roller control system is relatively complex and expensive according to the current state of the art.
  • wedges which can be displaced relative to one another in the direction of the axes of the rollers with height adjustment are arranged in the corresponding recesses in the bearing housing. It has proven to be particularly advantageous to arrange double wedges which can be displaced by a spindle with screw threads of opposite pitch, as described in DE-OS 32 38 938. Each of the two double wedges can be supported in a recess, in particular a corner recess.
  • the means for changing the distance between the bearing housings can, according to a last-mentioned variant, be flexible elements with a defined tension, which generate a counter pressure to a preload and are therefore partially pressed into the working position, depending on the selected stiffness.
  • This resilient element must be able to lift the upper roller with its bearings and the bearing housing when the preload is relieved.
  • the flexible elements which are preferably designed as spring elements, load cells or hydraulic elements, and which are interchangeable, are designed according to the preload pressure and the size of the roller force, as well as the desired adjustment range, and the characteristic curves are defined accordingly.
  • the means for changing the distance between the bearing housings can be mounted on the inlet or outlet side of the frame, the means for pivoting the second bearing housing are arranged accordingly.
  • the adjustable means for changing the distance between the bearing housings can preferably be controlled and controlled in an electronic control circuit by means of displacement sensors of the roll gap and / or strip thickness detection.
  • the stand for rolling or roll pressing is used for metals and non-metallic materials such as rubber, paper and plastics, in particular thermoplastics.
  • liquid metal can be introduced into the roll or casting gap 10 between the lower roll 12 and the upper roll 14 from the left or the right side from a nozzle, not shown.

  • the axis 58 of the spindle 60 does not run transversely to the axes 42, 44 of the rollers 12, 14, but parallel to it.
  • the spindle has two screw threads with opposite pitch, whereby the wedges 56 can be moved together or apart.
  • the base of the wedges 56 lies over the entire surface of a correspondingly designed surface of the housing 54 which is inclined at an angle ⁇ .
  • the housing 54 is on the end face closed for the double wedge with a flange 62, which are fastened to the housing by means of screws 64 and receive pins 66 on the lower side.
  • the threaded spindle 60 can be rotated by means of a manually operated ratchet 68, shown in broken lines in FIG. 2.
  • the scale 70 can be read for fine adjustment.
  • the riddle can be replaced by an electric, hydraulic or pneumatic drive of a known type. This is particularly necessary for automated control.
