Definitions

  • the invention relates to a roller straightening machine for straightening profiled rolling stock, with offset top and bottom, straightening rollers supporting shafts, which are mounted on the drive side and temporarily supported on the operator side by an adjustable support element in the direction of the straightening force on a housing part.
  • Roller straightening machines with such floating bearing shafts offer the great advantage that they are freely accessible on the operator side for changing the leveling rollers.
  • the high straightening forces that occur, especially when straightening large beams lead to a bending of the supporting shafts, so that a clear straightening process is no longer possible.
  • each support shaft on the operator side with an elongated bearing journal which is provided with a support bearing which in turn is enclosed by a bearing sleeve.
  • This bearing sleeve and thus the support bearing are supported in the direction of the downward directional force by a support designed as a pivot lever, which partially surrounds the bearing sleeve with a half-shell.
  • the swivel lever is pivotally mounted on two eccentrics of an actuating shaft.
  • the eccentrics allow the pivoting lever to be adjusted between two dead center positions, namely in a vertical support position and in an expansion position which causes the half-shell to be lifted off the bearing sleeve, which allows the pivoting lever to be pivoted outwards by means of hydraulic cylinders or to move the overall support sideways.
  • the invention is therefore based on the object in a straightening machine of the type mentioned with simple means variable support of the free, i.e. provide operator-side ends of the support shafts.
  • a preferred embodiment of the invention provides that the head ends of the adjusting spindles facing the support shafts have at least two support rollers in a yoke. These enable a support that fully meets the requirements if they are arranged at an angle of 60 ° to one another.
  • the yoke assigned to the two support rollers supports the rigidity of the roller bearing.
  • the support rollers on the roller bushes of the support shafts are assigned a tread, which can preferably be provided by a race. It is thus possible in a simple manner to provide a hardened running surface for the support rollers, namely by appropriate heat treatment of the running ring or by a suitable choice of material. It is advisable to equip the support shafts with a conical mounting or roller bushing, which offers the race a better fit compared to a cylindrical mounting sleeve or bushing and also keeps the games less.
  • running surfaces are advantageously shielded, for example by covering the pair of support rollers, they can be kept free of sinter.
  • the straightening machine 1 shown in FIG. 1 accommodates four and three support shafts 3 and 4, which are offset to the bottom, in its housing 2 at the top; On the inlet and outlet sides there is also a further supporting shaft 5 (see FIG. 2).
  • the upper and lower support shafts 3, 4 and 5 are mounted in a first bearing 7 on the drive side 6 and at a distance therefrom in a second bearing 8 in the housing 2, which essentially consists of side stands 9 and cross members 10 screwed to them.
  • Both the upper and the lower support shafts 3, 4 are driven by motors 11 and auxiliary motors 12, the weaker auxiliary motor 12 each driving the lower support shafts 4 is assigned in order to enable a towing speed which is easier to introduce the leveling material and is below the working speed.
  • adjusting spindles 14 connected to the housing 2 are arranged on the operating side 13 of the straightening machine 1. These can be set continuously against the free ends of the support shafts by means of a worm drive 16 actuated by a motor 15, of which the worm wheel 17 can be seen in FIG. 1 and the worm shaft 18 in FIG. 2, so that the support shafts 3, 4 are supported on both sides during the straightening operation, namely by the pitch-side bearings 7, 8 and the operator-side adjustment spindles 14.
  • a symmetrical arrangement of these support points can be achieved, which results in a central feeding of the profiles to be straightened by the straightening rollers 3, 4 arranged on the support shafts 3, 4 20 allows; the transport of the profiles 20 on the feed roller table is thus improved.
  • the head ends of the adjusting spindles 14 facing the support shafts 3, 4 are provided with a yoke 21 in which two support rollers 23 bearing against running surfaces 22 of the support shafts 3, 4 are at an angle 24 of 60 ° are stored to each other.
  • the tread 22 is made available by a race 25 which is arranged in a conical mounting bush 26 which also carries the straightening rollers 19.
  • a hydraulic clamping nut arranged below a protective hood 27 serves to pull the mounting bushing 26 onto the supporting shafts 3, 4.
  • the lower part of the frame or housing 2 of the straightening machine 1 accommodates two adjusting spindles 28, 29 which are driven by a gear motor 32 via worm wheels 30, 31 and are adjustable in height, so that the straightening plane on the one hand when changing to profiles of another size and others can be adapted to the roller tables of the rolling mill.
  • the worm drives 16, which enable a large stroke together with a high load-bearing capacity, from above and below against the free ends of the supporting shafts 3, 4 thus ensure, despite flying support, a bilateral during straightening operation, which is also used for preloading and optimizing the gap width Support of the support shafts 3, 4, which in particular allows the straightening of large and heavy profiles 20, since the support shafts 3, 4 can only bend as little as possible. This is promoted by the transmission of the supporting force to the housing 2 via the two supporting rollers 23 arranged in the yoke 21 at an angle of 60 ° to one another.
  • the adjusting spindles 14 can quickly be sufficiently far from the running surfaces 22, i.e. move the support shafts 3, 4 away so that there is sufficient free space on the operating side 13 to replace the old with a new set of straightening rollers 19.
