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 the roll change in a 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.
  • EP 0 773 073 B1 describes a device for the axial locking of support, working and / or intermediate rolls in a roll stand or other systems with a locking characteristic, for example a CVC rolling stand, with one for support rolls on the roll stand and for Work and intermediate rollers on the bending system or roll stand fastened, a latch plate having bolt guide and arranged with a for actuating the latch plate on the roll stand or on another mounting plane hydraulic piston / cylinder unit.
  • a disadvantage of this known or a similar design is their height, which narrows the available space for the arrangement of, for example, a framework piping and / or other components.
  • a device for axially setting the rollers of rolling stands in their uprights which permits deflection of the chocks in the axial direction, with bars guided displaceably perpendicular to the axial direction of the rollers. These bars fix the chocks against the uprights.
  • 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 latch.
  • resilient pressure which is generated by fixedly arranged hydraulic piston / cylinder units by moving the latch.
  • 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.
  • the combined compact construction unit of the invention in rolling operation in a perspective oblique front view, the combined compact construction unit of Fig. 2 at roll change, the combined compact construction unit of Fig. 3 in a sectional front view, the combined compact construction unit of FIG 2 in rolling operation in a perspective plan view, the combined compact construction unit of Fig. 3 and Fig. 4 in a roll change in a perspective plan view.
  • FIG. 1 shows a known roller locking device 1 with a spindle holder for a displacement device 5 mounted on the drive side with a separate work roll lock 6 and spindle chair 3 on a removal rail (lifting rail 4).
  • FIG. 2 shows in an oblique perspective front view a combined compact construction unit 11 according to the invention in rolling operation, comprising the roller locking device 10 and the drive spindle head mounting.
  • 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.
  • FIG. 3 The combined compact construction unit 1 1 of FIG. 2 in the position during a roll change is shown in FIG 3.
  • the hydraulic actuator 16 of the pivot bolt 12 of the upper roller was swung while the support arm 14 pivoted 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 head for the lower drive spindle, so that the lower roller can be changed after appropriate unlocking.
  • the construction unit 1 1 is shown in a cut front view in FIG.
  • the hydraulic actuating device 16 of the pivoting bolt 12 for the upper drive spindle head 19 and below the hydraulic actuating device 23 for the lower pivoting bolt 13 are arranged to the left of the construction unit 11.
  • FIGS 5 and 6 Further details are shown in Figures 5 and 6, in which, in a perspective plan view, the construction unit 1 1 of Figures 2 and 3 and 4 are shown enlarged.
  • Figure 5 shows the construction unit 1 1 with the closed by the hydraulic actuator 16 lock, wherein a closed retaining groove 22 was formed by the pivot bolt 12 with the non-rotating part, by which blocks the axial displacement in roll removal direction 31, displacements in the vertical direction are free.

Abstract

Après libération du verrouillage des cylindres axialement déplaçables, par exemple lors d'un changement de cylindre, le support et/ou le blocage nécessaire des têtes de broche d'entraînement ont lieu dans des dispositifs connus au moyen de leur propre unité mécanique séparée qui est actionnée hydrauliquement et est fixée sur la base, sur le porte-cylindre ou sur les rails de démontage des cylindres. En raison de l'espace très fortement réduit sur le côté entraînement des cylindres, un appareil de déplacement des cylindres pourvu d'un dispositif de verrouillage des cylindres et un support de tête de broche d'entraînement sur le côté entraînement ne peuvent souvent être réalisés que par des constructions complexes, encombrantes et lourdes. L'invention vise à simplifier en terme de conception le verrouillage des cylindres et le support des têtes de broche d'entraînement avec des moyens appropriés peu encombrants et économiques et à permettre le verrouillage et le support du côté entraînement des cylindres dans un espace par ailleurs insuffisant. A cet effet, le dispositif de verrouillage de cylindre (10) et le support de tête de broche d'entraînement sont combinés l'un avec l'autre en une unité de construction (11) compacte contenant un verrou pivotant (12) qui est disposé rotatif coaxialement autour du cylindre de déplacement axial (17) et qui est rentré pour le verrouillage et sorti pour le déverrouillage lors du fonctionnement des cylindres. Un bras latéral d'appui (14) qui fait partie du verrou pivotant (12) est simultanément rentré comme appui pour la tête de broche d'entraînement pendant la sortie du verrou pivotant (12).
