Description

Die Erfindung betrifft eine Vorrichtung zur axialen Verriegelung von Stütz-, Arbeits- und/oder Zwischenwalzen in einem Walzgerüst oder anderen Systemen mit Verriegelungscharakteristik, beispielsweise einem CVC-Walzgerüst, mit einer für Stützwalzen am Walzenständer und für Arbeits- und Zwischenwalzen am Biegesystem oder Walzenständer befestigbaren, eine Riegelplatte aufweisenden Riegelführung sowie mit einer für die Betätigung der Riegelplatte einerseits an dieser, am Walzenständer bzw. an einer anderen Montageebene angreifbar angeordneten hydraulischen KoLben/Zylinder-Einheit.The invention relates to a device for axial Locking support, work and / or intermediate rolls in a roll stand or other systems Locking characteristic, for example one CVC roll stand, with one for support rolls on the roll stand and for work and intermediate rolls on the bending system or Fastenable roller stand, having a locking plate Bolt guide as well as with one for the actuation of the Locking plate on the one hand on this, on the roller stand or on another assembly level arranged vulnerable hydraulic piston / cylinder unit.

Vorrichtungen zur axialen Verriegelung von Stütz-, Arbeitsund/oder Zwischenwalzen in einem Walzgerüst sind seit Langem bekannt. Bei diesen hat sich eine praxisübliche Bauart herausgebildet, bei der einerseits an der Riegelplatte entsprechend einer in der Figur 1 gezeigten beispielhaften Ausführung vom Stand der Technik ein die Riegelplattenführung überragender Gabelkopf und andererseits an der Anbauebene des Walzenständers oder des Biegesystems neben der Vorrichtung ein Stützbock angebracht und zwischen diesen in einer zur Riegelplatte parallelen Ebene die Kolben/Zylinder-Einheit mit Stangenkopf und Gelenklager angelenkt ist.Devices for the axial locking of support, work and / or Intermediate rolls in a roll stand have long been known. These have a construction that is common in practice formed on the one hand on the locking plate corresponding to an example shown in FIG State-of-the-art version of the transom plate guide outstanding clevis and on the other hand at the mounting level of the Roll stand or the bending system next to the device Support bracket attached and between them in a parallel to the locking plate The piston / cylinder unit is articulated with the rod head and spherical bearing.

Von Nachteil bei dieser bekannten oder einer ähnlichen Bauart ist einerseits die Bauhöhe, welche den verfügbaren Platz zur Anordnung beispielsweise einer Gerüstverrohrung und/oder für andere Bauteile einengt.The disadvantage of this known or a similar design is on the one hand Height, which the available space for the arrangement of, for example, scaffolding piping and / or for other components.

Nachteilig ist weiterhin die Anzahl der benötigten Bauteile wie Stangenkopf mit Gelenklager, Stützbock, Zylinder mit Schwenkstange und Gelenklager, Bolzen und Sicherungselemente, Hydraulikschläuche, Spezialschrauben und Scheiben. Dies ergibt insgesamt einen vergleichsweise hohen Aufwand für Fertigung, Montage und Wartung.Another disadvantage is the number of components required, such as the rod head Spherical bearing, support bracket, cylinder with swivel rod and spherical bearing, bolt and Securing elements, hydraulic hoses, special screws and washers. This overall results in a comparatively high outlay for production, assembly and maintenance.

Und nicht zuletzt verursacht der Angriffspunkt der Kolben/Zylinder-Einheit in einer zur Führungsebene beabstandeten Angriffsebene ein schädliches Kippmoment der Riegelplatte in ihrer Führung, die dadurch insbesondere bel Anfall von Verschmutzung verschleißträchtig und wartungsbedürftig ist und äußerstenfalls auch zum Klemmen neigen kann.And last but not least, the point of attack causes the piston / cylinder unit in one a harmful overturning moment from the attack plane spaced apart from the management level the locking plate in its guide, which in particular bel pollution is susceptible to wear and tear and requires maintenance, and at most also may tend to jam.

Aus der FR-A-1 122 538 ist eine ein Ausweichen der Einbaustücke in axialer Richtung ermöglichende Vorrichtung zum axialen Festlegen der Walzen von Walzgerüsten in ihren Ständern bekannt, mit senkrecht zur Achsrichtung der Walzen verschiebbar geführten Riegeln. Durch diese Riegel werden die Einbaustücke gegenüber den Ständern festgelegt. Zumindest an einer Seite der Walze wirken die Riegel mit schräg zur Walzenachse gerichteten Keilflächen auf mit gleicher Schräge versehene Keilflächen an den Einbaustücken mit nachgiebigen Druck ein, der durch mit Druckmittel beaufschlagte Kolben von ständerfest angeordneten Hubzylindern durch Verschieben der Riegel erzeugt wird. Dadurch ist eine Sicherung beim Zubruchgehen der Walzen geschaffen, da die Keilflächen der Riegel bei übergroßen axialen Kräften der Walze an den Keilflächen der Einbaustücke abgleiten und die Riegel gegen die Kraft des Druckmittels aus dem Bereich des Einbaustückes heraus bringen. Die an der anderen Seite der Walze am Ständer angeordneten Riegel können dabei im Einbaustück vorgesehene Schlitze eingreifen oder gleichfalls durch Keilflächen ausweichbar gestaltet sein.From FR-A-1 122 538 is a dodging of the chocks in the axial direction enabling device for axially fixing the rolls of roll stands known in their stands, with perpendicular to the axial direction of the rollers led bars. With these bolts the chocks are opposite the stands. The bars act at least on one side of the roller with wedge surfaces directed obliquely to the roller axis with the same slope provided wedge surfaces on the chocks with compliant pressure, the by pressurized pistons of lifting cylinders arranged in a fixed position is generated by moving the latch. This is a backup created when the rollers break, because the wedge surfaces of the bars for oversized axial forces of the roller slide on the wedge surfaces of the chocks and the bolts against the force of the pressure medium from the area of the chock release. The one located on the other side of the roller on the stand Bolts can engage slots provided in the chock or can also be designed to be evasive by means of wedge surfaces.
