Definitions

  • the invention relates to a device for bracing rolling disks or rolling rings, preferably in a floating arrangement, according to the preamble of claim 1.
  • DE-OS 26 39 543 and 25 49 709 have the object of such a device in which a tie rod is inserted into the drive shaft designed as a hollow shaft.
  • a tie rod By axially stretching the tie rod, axially directed compressive stresses are generated, as a result of which the roller disk is clamped axially with its two end faces between plane-parallel surfaces.
  • the roller disc is connected to the drive shaft in a rotationally fixed manner by inserting a conical sleeve into the bore of the roller disc and under the action of the applied radial forces, the rolling ring is clamped on the drive shaft.
  • the object of the invention is to achieve the rotationally fixed bracing of the rolling rings with the drive shaft exclusively by applying axial compressive forces and axial positive locking and avoiding any radial clamping forces.
  • the rolling ring is seated on a rolling ring carrier that is flange-shaped towards the drive shaft, on the side of which facing away from the drive shaft, a support disc lies flat against the common side surfaces of the rolling ring and the rolling ring carrier, and the supporting disc is detachably connected to the rolling ring carrier and the end face of the roller ring carrier facing the drive shaft can be positively coupled to the end face of the drive shaft facing this.
  • the rolling ring may be attached to the rolling ring carrier using an adhesive connection.
  • the advantage of the two exemplary embodiments for bracing rolling disks or rolling rings is that the rolling bodies are connected to the drive shaft in a rotationally fixed manner only when pure axial forces are applied.
  • the hydraulic clamping device is used on the one hand by lengthening or stretching the tie rod to axially brace the roller body on the one hand and on the other hand to establish a positive connection via an end toothing between the roller body and drive shaft for the safe transmission of the torque from the drive shaft to the roller body.
  • the front toothing also serves to center the Roll body opposite the drive shaft.
  • the interlocking connection is formed from a two-sided front toothing, which is brought into engagement with the drive shaft at the same time as the axial clamping forces are applied by the hydraulic clamping means with additional centering of the roller body on the tie rod part.
  • Narrow rolling rings are used for cost reasons if only small caliber widths are cut on the circumference of the rolling ring according to the rolling program.
  • the outer ring part of the hydraulic tensioning unit with its end face facing the rolling ring can lie directly against the end face of the rolling body opposite this.
  • a sleeve can advantageously be rotatably seated on which the roller body and the cylinder of the clamping means are guided with radial play. This advantageously serves to protect the tie rod pin by protecting it from damage when changing the roll and making the roll change easier.
  • the hydraulic tensioning unit consists of a tensioning piston surrounding the tie rod and a tensioning cylinder, the tensioning piston being attached to the head end of the train by means of a threaded nut is anchored and the clamping cylinder is supported on its side facing away from the rolling body by means of a threaded ring on the circumference of the clamping piston.
  • the tie rod is advantageously either releasably connected with its one end engaging far into the hollow shaft, or the entire hollow shaft is fixed to its end with respect to its end.
  • roller 1 denotes a part of a stand of a roll stand, in which a set of rolls consisting of two rolls is arranged in a known manner.
  • a set of rolls consisting of two rolls is arranged in a known manner.
  • For the rolling of wire be in the intermediate and finishing lines preferably consisting of roller disks 2 or roller rings used roller sets in a cantilevered arrangement.
  • the rolling disks 2 are arranged with their peripheral surfaces opposite one another on parallel drive shafts along the rolling line. Recesses 2a forming the rolling caliber K are screwed in on the peripheral surfaces.
  • the rolling disks 2 each have a radial play S on a sleeve 4 so that they can rotate, by the sleeve 4 being supported on the free head end 5a of a tie rod 5.
  • the sleeve 4 serves as a wear part for protecting the surface of the tie rod 5, in particular when changing the roll, but the roller disks 2 could alternatively also be seated directly on the free head end 5a of the tie rod 5 with radial play S.
  • the tie rod 5 is screwed with its shaft 5b into the bore of a threaded drive shaft designed as a hollow shaft 7.
  • the shaft 5b is designed to protrude far into the hollow shaft 7.
  • the tie rod 5 can also penetrate the hollow shaft 7 up to its drive end and can be fixed there by means of a hammer head.
  • each roller disc 2 is mounted in the roll stand 1 via a slide bearing 8 and an eccentric bushing 9 for radial roll adjustment.
  • a slide bearing 8 and an eccentric bushing 9 for radial roll adjustment.
  • the hydraulic clamping means 12 consists of an annular piston 12a and an annular cylinder 12b.
  • the ring cylinder 12b rests on the side facing away from the roller disc 2 against a threaded ring 13, which can be rotated when the pressure medium 12 is introduced to elongate the tie rod 5.
  • the annular piston 12b In the direction of the longitudinal axis of the tie rod 5, the annular piston 12b has a pressure medium channel 12c with a coupling nipple 12d, which serves as a connection to a pressure medium supply line, not shown.
  • the actual pressure medium chamber 12e lies between the sealing rings 14, 15.
  • the ring cylinder 12b rests with its end face facing the roller disc 2 against the end face of the roller disc 2 facing it, while the other end face of the roller disc 2 is provided with an end-face central toothed ring 17a which has a central toothed ring 17b corresponding to the end face of the hollow shaft 7 , center the roller disc 2 on the sleeve 4 at the same time, by) introducing pressure medium into the pressure medium chamber 12e by applying pure axial forces.
  • the roller disc 2 is axially clamped plane-parallel, non-rotatably on the free head end 5a of the tie rod 5 or the sleeve 4 and, under the action of the axial forces over 5, the frontal central ring gears 17a, 17b can be positively coupled to the drive shaft 7 designed as a hollow shaft, from which the torque is also transmitted to the roller disc 2 via the positive connection. The occurrence of any radial forces in the roller disc is avoided.
  • FIG. 2 and 3 is a further embodiment 1, the use of a rolling ring 20 or a very narrow rolling ring 20a made of hard metal as part of the roller fastening shown in principle in FIG. 1 is shown as an alternative to the rolling disk 2 made of chilled cast iron according to FIG. 1.
  • 21 denotes a rolling ring carrier which has a flange-like ring surface on the drive shaft side, against which the corresponding side surface of a rolling ring 20 bears.
  • the rolling ring 20 is seated free of play or fastened by means of an adhesive connection on the outer circumference of the rolling ring carrier 21 in order to be able to absorb the rolling forces.
  • the end face of the rolling ring carrier 21 facing the hollow shaft 7 is provided with an end gear ring 27a, the teeth of which form fit in a corresponding tooth ring 27b on the opposite end face of the hollow shaft 7 under the axial force of the hydraulic clamping means 12.
  • the rolling ring carrier 21 sits on the rolling disk 2 with radial play on the sleeve 4 or directly on the free head end 5a of the tie rod 5.
  • the rolling ring 20 also has a caliber K cut on its circumference as a caliber roller.
  • Fig. 3 shows a further embodiment of the rolling ring attachment, in which a particularly narrow rolling ring 20a with smaller widths of the caliber K abuts on both sides of support rings 23 as filler pieces and otherwise between a support plate 22 detachably connected to the rolling ring carrier 21 by means of threaded bolts 22a and the flange of the rolling ring carrier 21 on the drive shaft side is set.
  • Narrow rolling rings are used for smaller caliber widths in order to save costs.
  • the rolling ring 20a is also seated on the rolling ring carrier 21 without play or is fastened to it by means of an adhesive connection.
  • the roll ring carrier 21 has also at its the hollow shaft 7 end face facing an end-side gear 27a, with a corresponding end-side sprocket 27b of the facing end side of the hollow shaft 7 a detachable form-fitting connection by: ' Figure 4 forms..
  • the threaded nut 10 is unscrewed from the free end of the tie rod 5, so that the roller disk 2 can be pushed onto the sleeve 4 as a roller body.
  • the clamping means 12, consisting of clamping piston 12a, clamping cylinder 12b and threaded ring 13 is pushed onto the sleeve 4.
  • the threaded nut 10 is again placed on the end of the tie rod 5 and screwed to it, so that the clamping means 12 with the roller disc 2 can lie firmly against the end face 17b of the drive shaft 7 and the sprockets 17a and 17b are positively coupled with one another.
  • a pressure medium supply line is then connected to the coupling nipple 12d from the outside and pressure medium is supplied to the pressure medium chamber 12e via the pressure medium channel 12c.
  • the expansion path of the tie rod 5 is adjusted and the threaded ring 13 is readjusted and brought into contact with the tension cylinder 12b with its roller-side end face.
  • the pressure medium is then released, so that a plane-parallel bracing of the roller disc 2, which is under the action of an axial force, and a fixed axial shape final connection between roller 2 and drive shaft 7 is made.
  • the pressure medium supply line is released from the coupling nipple 12d.
