Definitions

  • the invention relates to a roller fastening for straightening roller machines with a roller bushing arranged on a straightening pin, on which the straightening roller can be clamped by means of a tension nut adjustable on the roller bushing acts conical clamping sleeves with adjacent conical surfaces, which cause a radial tensioning of the straightening roller when the clamping sleeves move axially.
  • the known roller attachment (DE 36 03 371 A1) has a hydraulically operated clamping head located at the free end of the rotatable roller axis, which is connected to a tension rod arranged in a central bore of the roller axis and supported in it, the annular piston of the clamping head being attached to the End face of the roller axis is supported and the roller sleeve receiving the straightening roller is braced against a collar on the roller axis by means of a bayonet ring which interacts with the clamping head.
  • the straightening pin is tapered at least over a partial length towards the clamping head and the inside surface of the roller bushing is provided with a corresponding cone.
  • the conical surfaces can be pressed together using the clamping head or tie rod.
  • the invention is based on the object of creating a play-free straightening roller fastening on a cylindrical straightening pin, with the simplest fastening means.
  • roller bushing cylindrically and to provide it with radial slots which are evenly distributed over the circumference and extend in the region of the straightening roller in the longitudinal direction of the roller bushing.
  • the bracing force acting between the roller sleeve and the straightening roller is simultaneously transmitted to the straightening pin of the straightening roller machine, namely in that the webs of the roller sleeve remaining between the slots move radially inwards.
  • This ensures a non-rotatable connection with the roller sleeve and the straightening roller arranged on it due to the non-positive connection of roller sleeve webs and straightening pins.
  • the present invention not only allows a secure tensioning of the straightening rollers on the straightening pins of the machines with the simplest means, it also offers the advantage of inexpensive retrofitting of older machines which are equipped with cylindrical straightening pins so that they can also be enjoyed clearance rolls built without play come. This can also significantly improve the judging results of old machines.
  • the old roller bushes can often be used, which only need to be slotted in the sense of the invention.
  • the basic idea of the present invention is that an additional fastening of the roller bushing on the straightening pin can be dispensed with in that the clamping sleeve tensioning provided for the straightening roller fastening on the roller bushing is simultaneously used. With just a single fastener, all components can be fixed.
  • a clamping nut 2 is arranged on the roller bushing 1, which pushes two conical clamping elements 7 into one another via the spacer sleeve 4, the straightening discs 5 and the spacer rings 6.
  • radial forces are exerted on the straightening roller 3 and the roller bushing 1.
  • the roller bushing 1 is slit radially several times in the region of the straightening roller (FIG. 2).
  • the webs 8 formed in this way are capable of bending and are pressed against the directional pin 9 by the radial forces generated by the clamping elements 7. This creates a frictional connection between straightening roller 3 and straightening pin 9, which clamps the roller bushing 1 in such a way that neither an additional fastening system against displacement in the axial direction nor feather keys are required to transmit the torques.
  • the side windows 5 effect the guidance of the straightening material in the axial direction in a known manner.
  • the ring piston 10 in the clamping nut 2 is pressurized by means of an electrically operated, mobile hydraulic pump via a hose.
  • the annular piston 10 presses against the spacer sleeve 4 and pushes the conical clamping elements 7 into one another via side disks 5 and spacer rings 6 against an abutment in the form of a collar on the roller bushing, so that these are spread apart.
