Definitions

  • the invention relates to a roll locking device which axially locks the axially displaceable rolls of hot rolling mills, Steckel rolling mills, heavy plate rolling mills, especially quarto stands for rolling and for transmitting the forces required for axial displacement, without hindering the vertical mobility of the rollers and in a roll change the Rollers unlocked again, wherein the drive spindle heads are held in the vertical direction on the drive side of the rollers with a drive spindle head holder.
  • the point of application of the piston / cylinder unit in a plane spaced apart from the guide plane attack level causes a damaging tilting moment of the locking plate in their leadership, which is wear-prone and in need of maintenance particularly in case of contamination and may also tend to jamming.
  • the pamphlets WO 97/27011 and US 3,208,260 describe roll locking devices for axially displaceable rolls in rolling mills.
  • FR 122 538 A1 From the FR 122 538 A1 is a dodging the chocks in the axial direction enabling device for axially fixing the rolls of rolling stands in their uprights known, with slidably guided perpendicular to the axial direction of the rolls bars. These bars fix the chocks against the uprights. At least on one side of the roller, the bars act with inclined to the roll axis wedge surfaces on the same slope provided wedge surfaces on the chocks with resilient pressure, which is generated by fixedly arranged hydraulic piston / cylinder units by moving the bolt.
  • roller locking device and the drive spindle head holder are combined to form a compact construction unit comprising a coaxially about the axial displacement cylinder rotatably arranged pivot bolt, which is pivoted in the rolling operation for locking and unlocking is swung out, wherein during the pivoting of the pivot bolt at the same time a lateral support arm, which is part of the pivot bolt, is pivoted as a support for the drive spindle head.
  • the inventive design of the pivot bolt with a laterally projecting support arm and the concentric space-saving arrangement of the pivot bolt about the displacement axis can advantageously be performed simultaneously in an axial stroke locking the rollers and holding the drive spindle head.
  • the pivot bolt forms in the closed state with the non-rotating part of a closed retaining, which receives the corresponding counterpart on the chock of the roller for the purpose of Axialfix ist.
  • the support arm for the drive spindle is then pivoted downwards in order not to hinder the vertical working range of the roller. If the pivot bolt is swung out to change the rollers, the retaining groove is in the direction of removal of the rollers open. The support arm for the drive spindle head is then pivoted and holds him vertically in position.
  • roller locking device and drive spindle head holder can not only be used for the upper drive spindle head, but this combination is basically for the lower drive spindle head conceivable and may also be useful, in which case optionally arranged below the lower drive spindle head rigid and / or lifting and lowered trained pad can be provided.
  • the combination according to the invention is particularly suitable for use on the drive side of the rollers, but can of course also on the operator side with a corresponding change be used of the pivot bolt.
  • FIG. 1 is a known roller locking device 1 with spindle holder for a drive side mounted displacement device 5 with separate work roll latch 6 and 3 spindle spindle on a removal rail (lifting rail 4).
  • FIG. 2 shows in an oblique perspective front view of a combined compact construction unit 11 of the invention according to the invention in the rolling operation, consisting of the roller locking device 10 and the drive spindle head mount.
  • the coaxial about the upper axial displacement cylinder 17 arranged pivot bolt 12 for the upper roller is pivoted by the hydraulic actuator 16 for locking the upper roller in the direction of the axis of axial displacement 30.
  • the support arm 14 for the upper drive spindle head was swiveled downwards with the same stroke of the actuating device 16.
  • the provided for later holding the lower drive spindle head raised and lowered formed support 15 is still in a lower position.
  • the combined compact construction unit 11 of Fig. 2 in the position at a roll change shows the FIG. 3 ,
  • the pivot bolt 12 of the upper roller has been swung out and at the same time pivoted in the support arm 14 for the upper drive spindle head.
  • the roller can now be removed in the removal direction 31 for changing the rollers.
  • the support 15 was raised for the lower drive spindle head, so that the lower roller can be changed after appropriate unlocking.
  • FIG. 4 In order to emphasize the positioning of the individual actuators of the combined compact construction unit 11 in a roll change, is in the FIG. 4 the construction unit 11 is shown in a sectional front view. In addition to the right in the drawing figure arranged on top of one another drive spindle heads 19, 20 are the two likewise superimposed axial displacement cylinder 17, 18 of the construction unit 11. In the Fig. 4 On the left next to the construction unit 11, the hydraulic actuator 16 of the upper drive spindle head pivot bar 12 and below the lower swing latch hydraulic actuator 23 are disposed.
  • FIGS. 5 and 6 More details are in the FIGS. 5 and 6 in which, in a perspective top view, the construction unit 11 of FIG Figures 2 or 3 and 4 are shown enlarged, refer to.
  • FIG. 5 shows the construction unit 11 with the closed by the hydraulic actuator 16 lock, wherein by the pivot bolt 12 with the non-rotating part, a closed retaining groove 22 was formed by the axial displacement in roll removal direction 31 blocks, displacements in the vertical direction, however, are free.
  • FIG. 6 is shown that by opening the lock and the retaining groove 22 has been opened so that displacements are possible in roll removal direction 31 for changing the rollers.
