Definitions

  • the invention relates to a roll stand of the type specified in the preamble of claim 1.
  • a roll stand is known in which a force element in the form of a hydraulic cylinder is arranged at a distance from the actuator to compensate for roll deflections between specially provided roll neck extensions so that a sufficiently long lever arm results.
  • the invention has for its object to design a roll stand so that a high accuracy in maintaining the roll gap can be achieved without extreme demands on the storage, in particular of the roll that can be delivered, and also in applications where the reaction forces of the rolling stock on the pair of rolls are low or are indefinite.
  • the roll journals 8 and 8 'of the deliverable roll 4 or the fixedly mounted roll 2 are each in two separate radial bearings 11, 12 and 11', 12 'captured.
  • the roller 2 is fixedly mounted with respect to the stand 1.
  • the roller 4 can be fed to the roller 2 for the purpose of adjusting the gap width 5 and is not connected to the stand 1, it is only guided laterally to prevent pendulum movements (for example by means of guides fastened to the stand on both sides of the bearing 11, not shown).
  • the roller drive is not shown for the sake of simplicity. It can be a roll stand for finish rolling plastic or metal foils etc. or e.g. a calender with coating rollers for finishing, especially coating material webs. act, so preferably for applications in which it is important to maintain a relatively narrow nip 5 with high absolute accuracy (in the range of micrometers) and with little or practically no counterforce (deformation forces) on the part of the material web on the rollers.
  • a hydraulic adjusting cylinder 13 is used as the adjusting element for adjusting the roller spacing, the cylinders of which are attached to the bearing 11 'and the piston rod of which is attached to the bearing 11. Contrary to the feed direction of the actuating cylinder 13, the other pair of bearings 12, 12 'is clamped by means of four compression springs 45, as a result of which any bearing play is permanently eliminated, so that the gap is regulated extremely precisely is also possible without the need for specially selected and therefore expensive bearings.
  • the springs 45 are positioned by two parallel guide rods 44 which extend between arms of the bearings 12, 12 'and slide in guide bores thereof.
  • a carrier 40 is also slidably guided on the guide rods 44 and held approximately in the middle between the rollers 2 and 4 between two compression springs 45.
  • a control circuit for the automatic control of the gap width is indicated only schematically and in a simplified manner with actual value line 21, control amplifier 24, setpoint input 22, control signal line 25, control valve 31, hydraulic pump 30 and hydraulic pressure line 32 to the control cylinder 13.
  • Each of these bearings 52, 52 ' is designed as a sliding shoe, formed from two supporting bodies 54 and 54', which are rigidly connected in pairs by a shield 53, 53 '. Between the bearings 11 and 11 'again extend two parallel guide rods 56, on which each bearing shoe 52, 52' is slidably guided by means of holes provided in the support bodies. Compression springs 55 are provided as force members counteracting the actuator 13, which springs, which are guided in bores of the support bodies, are clamped between the bearings 52, 52 '.
  • the support bodies 54, 54 ' are preferably provided with wear-resistant bearing surfaces, on which the spring forces are slidably transmitted to the rollers and from their pins back to the bearings 11, 11'.
  • compression springs 55 it is also possible, for example, to use one or more hydraulic pressure cylinders (with constant counterforce) or, if appropriate, massive, adjustable compression rods as particularly "hard” mechanical springs.
  • the support bodies 54, 54 ' can be provided with roller bearings instead of the sliding linings.
  • electromotive actuating spindle drives can also be used as actuators in the sense of the invention for slow-speed rollers.
