Definitions

  • the invention relates to a roller straightening machine, in particular for beams with a large web height, in which the lower straightening rollers can be placed on the fly on support shafts which are axially displaceable in a bearing housing, which rests on vertical, motor-driven lifting elements, in vertical guides of a horizontally displaceable one Carriage is movable up and down, such as known from DE-A-2850397.
  • the invention has for its object to improve the generic roller straightening machine so that it can absorb the increased loads without it being necessary to dimension the supporting shafts of the straightening rollers and the bearing housing as well as the carrying slides and the stand frame which accommodate them.
  • This object is achieved in that the bearing housing receiving the support shaft of the straightening roller can be pivoted about an inclination adjustment axis running perpendicular to the support shaft axis. This creates the possibility of presetting the support shaft inclined to its horizontal axis position in accordance with the direction and size of the back pressure to be expected from the directional deformation.
  • an axial change in the position of the support shaft can be made.
  • the inclination presetting of the support shaft can, as the invention further provides, be brought about by the fact that the vertical guides of the bearing housing can be pivoted about the inclination adjustment axis.
  • the vertical guides of the bearing housing can, according to the invention, consist of pivot bearings guided therein for bearing journals which are arranged in the support slide and can be inserted into the pivot bearing and form the inclination adjustment axis, and the pivot bearings consist of a bearing bore for bearing stones having the bearing journal.
  • the vertical guides and the inclined guides for the bearing housing can also consist of parallel guide strips arranged laterally on this and extending transversely to the horizontal bearing axis plane, which bear against slightly convex, opposing bearing surfaces of guide strips arranged on the support slide.
  • the lifting elements can be driven as a function of and / or independently of one another.
  • the lifting elements consist of lifting spindles driven by a common drive shaft, of which a first is arranged in an area below the straightening rollers and a second in an area below the bearing of the supporting shaft facing away from the straightening roller
  • the first can be used according to the invention
  • Lift spindle can be switched off in the common drive via a magnetic shaft coupling, with the result that the inclination presetting can be carried out with the aid of the second lifting spindle, possibly with correction of the resulting axial displacement of the supporting shaft with the aid of a device for the axial displacement of this shaft.
  • the actuating movements of the lifting elements and the elements for the axial displacement of the supporting shafts are, according to the invention, brought about jointly via a control device connected to a manipulated variable specification computer.
  • the support shaft 1 is mounted in the bearing housing 2 in bearings 3 and 4. Outside of both bearings 3 and 4, the straightening roller is pushed onto the pin 1a, which consists of the two straightening discs 5 and the mounting bush 6 with spacer bush and clamping nut consists. These elements are held together by a hydraulic nut with a bayonet fitting, not shown, which is placed on the pin 1a from the outside.
  • the straightening disks of the straightening disks acting from above on the carrier T to be straightened of the upper, not vertically adjustable straightening rollers, which are otherwise not shown, are indicated by 8; these are also on the fly, stored directly in horizontally displaceable bearing housings without lifting elements.
  • an axial adjusting device consisting of a threaded bushing 9 with the axial bearings and a spur gear drive 10 connected to the threaded bushing engages thereon.
  • the bearing housing 2 is supported by lifting spindles 11 and 12, which are arranged in the support carriage 13, which laterally surrounds the bearing housing 2 with support walls 13a (cf. also Fig. 2).
  • the two support spindles 11 and 12 are driven together by a drive shaft 14, indicated in broken lines.
  • This drive shaft 14 can be switched off by the drive, not shown, by the electromagnet-tooth coupling 15, which is also shown in broken lines.
  • the support slide 13 is horizontally displaceable in the machine stand 16 in a manner not shown.
  • the bearing housing 2 has vertical guides 17 for a bearing block 18 on both sides.
  • a bearing pin 19 engages in the bearing bore 18a and sits firmly in the walls 13a of the support slide 13 which laterally enclose the bearing housing 2.
  • pairs of guide strips 20 are arranged on the bearing housing, on laterally projecting retaining lugs 22 transversely to the horizontal axis plane of the supporting shaft 1. These guide strips 20 rest against the associated, slightly convex bearing surfaces of corresponding guide strips 21, which are arranged laterally on the support slide 13.
  • the support shaft 1 can be moved into the provisional setting position shown in FIG. 1 by simultaneous driving of the lifting spindles 11 and 12 and then after switching off and if necessary switching on the electromagnetic tooth coupling 15 and actuating only the lifting spindle 11 or re-actuating both lifting spindles 11 and 12 together as well as introducing axial displacement corrections with the aid of the displacement device 9, 10 into a final setting position inclined to the horizontal. All necessary travel commands are issued on the basis of empirical values from control devices which are connected to a manipulated value computer.
