Definitions

  • the invention relates to a roller straightening machine for straightening profiled rolling stock, with staggered upper and lower straightening rollers Support shafts that are mounted on the drive side and temporarily on the operator side by a adjustable support element in the direction of the directional force supported on a housing part are, on the operating side from above and below against the support shafts adjustable spindles are arranged.
  • a roll straightener of this type has become known from GB-A-2 033 802.
  • the floating bearing shafts offer the great advantage that they are freely accessible on the operator side for changing straightening rolls.
  • the invention is therefore based on the object in a straightening machine a variable support of the free, i.e. to provide operator-side ends of the support shafts, in particular the support area to be improved.
  • This object is achieved according to the invention in a generic roller straightening machine in that the support shafts facing head ends of the adjusting spindles in a yoke at least two Have support rollers.
  • the yoke assigned to the two support rollers supports the Stiffness of the roller bearings and enables one to meet the requirements completely appropriate support when the rollers are at an angle of 60 ° to each other are arranged.
  • the support rollers on the Roller bushings of the support shafts assigned a tread can preferably be provided by a race.
  • treads are advantageously shielded, for example by covering the pair of support rollers, they can be keep free from sinter.
  • the straightening machine 1 shown in Fig. 1 takes in its housing 2 above four and three offset supporting shafts below 3 or 4 on; the inlet and outlet side is also below yet another support shaft 5 (see FIG. 2) arranged.
  • the upper and lower support shafts 3, 4 and 5 are in a first Bearing 7 on the drive side 6 and at a distance from it in one second bearing 8 stored in the housing 2, which consists essentially of Side stands 9 and cross members 10 screwed to them consists.
  • Both the upper and the lower support shafts 3, 4 are driven by motors 11 and auxiliary motors 12, respectively the weaker auxiliary motor 12 in each case the lower support shafts 4 is assigned to the introduction of the target material relieving, below the working speed To enable towing speed.
  • the worm shaft 18 can be seen are continuously against the free ends of the support shafts, so that the support shafts 3, 4 on both sides during the straightening operation are supported, namely by the pitch-side bearings 7, 8 and the operator-side adjustment spindles 14 a symmetrical arrangement of these support points is achieved, which is a central feeding of the on the support shafts 3, 4 arranged straightening rollers 19 profiles 20 to be straightened enables; the transport of the profiles 20 on the feed roller table is improved.
  • FIG. 2 they are the supporting shafts 3, 4 facing head ends of the adjusting spindles 14 with a Provided yoke 21 in which two against treads 22 of the Support shafts 3, 4 support rollers 23 at an angle 24 of 60 ° to each other are stored.
  • the tread 22 will provided by a race 25, which in a conical assembly bushing 26 also supporting the straightening rollers 19 is arranged.
  • a protective hood 27 arranged hydraulic clamping nut.
  • the lower part of the frame or housing 2 of the leveler 1 takes two adjusting spindles 28, 29, which are on worm gears 30, 31 are driven by a geared motor 32 and are adjustable in height, so that the leveling on the one hand Transition to profiles of a different size and to another the roller tables of the rolling mill can be adapted.
