Abstract
Description
Die Erfindung bezieht sich auf ein Walzgerüst mit, jeweils beidendig in einem Getriebegehäuse parallel nebeneinander gelagerten Exzenterlagerhülsen für, in diesen, ebenfalls beidendig, gelagerte Walzentragwellen mit lageraußenseitig fliegend auf diese aufbringbaren Walzscheiben und, zwischen den Tragwellenenden angeordnete, durch eine Umfangsausnehmung der Exzenterlagerhülse hindurch mit einem Antriebsritzel kämmenden, stirnverzahnten Wellenabschnitten.The invention relates to a roll stand, both ends eccentric bearing sleeves mounted in parallel in a gearbox housing for, in both of these, also double-ended, roller supporting shafts with the outside of the bearing flying onto these attachable Rolling disks and, arranged between the support shaft ends, by a peripheral recess of the eccentric bearing sleeve with a Drive-meshing, spur-toothed shaft sections.
Walzgerüste dieser Art, bei denen die Walzscheiben und Walzarmaturen infolge der fliegenden Lagerung der Walzscheiben unter Verwendung von Exzenterlagerhülsen die Anstelleinrichtungen und die Walzarmaturen sehr gut zugänglich sind, werden in der Regel mit Walzscheiben kleinen Durchmessers ausgestattet, die bei verhältnismäßig hohen Drehzahlen mit geringen Walzkräften entsprechend geringe Breitungen des Walzgutes erzielen. Die Walzentragwellen lagern dabei in dünnwandigen, hochbelastbaren Gleitlagern. Die kleinen Durchmesser der Walzscheiben erlauben auch die Verwendung von Walzscheiben aus Hartstoffen oder Hartmetallen, die besonders formfest sind und hohe Kaliberstandzeiten aufweisen.Roll stands of this type, in which the rolling disks and rolling fittings due to the flying storage of the rolling disks using of eccentric bearing sleeves, the adjusting devices and the rolling fittings are very accessible, usually with rolling disks small diameter equipped at relatively high Speeds with low rolling forces corresponding to low spreads of the rolling stock. The roller supporting shafts are stored in thin-walled heavy-duty plain bearings. The small diameter of the Rolling disks also allow the use of rolling disks Hard materials or hard metals that are particularly dimensionally stable and high Have caliber tool life.
Ein Nachteil dieser Walzgerüste ist die, im Vergleich zu Walzgerüsten mit beidseitig der Walzscheiben gelagerten Walzentragwellen geringere Gerüststeifigkeit, die die Einsatzmöglichkeiten solcher Walzgerüste für das Präzisionswalzen stark einschränkt. A disadvantage of these roll stands is that compared to roll stands with roller support shafts mounted on both sides of the roller disks lower scaffold rigidity, which the possible uses of such Rolling stands for precision rolling are severely restricted.
Der Erfindung liegt die Aufgabe zugrunde, die Steifigkeit der gattungsgemäßen Walzgerüst so zu erhöhen, daß die Gerüste auch beim Präzisionswalzen verwendet werden können.The invention has for its object the rigidity of Generic roll stand to increase so that the stands at Precision rollers can be used.
Die Aufgabe wird dadurch gelöst, daß eine der beiden Exzenterlagerhülsen in einer, einarmigen Hebel-Schwinge angeordnet ist, die um eine, quer zur Längsmittenachse der Walzentragwelle verlaufende Achse schwenk- oder neigbar über ein elastisches, einstell- und festlegbares Stellglied gegen das Getriebegehäuse abgestützt ist.The object is achieved in that one of the two eccentric bearing sleeves is arranged in a, one-armed lever swing arm, which around one that runs transversely to the longitudinal center axis of the roller supporting shaft Axis can be swiveled or tilted using an elastic, adjustable and lockable actuator is supported against the gear housing.
Diese erfindungsgemäße Ausbildungsform des Walzgerüstes erlaubt die Einstellung einer jeweils gewünschten Steifigkeit des Walzgerüstes, wobei der geringe Einstellhub des elastischen Stellgliedes die Einstellkinematik der, von dem Exzenterlagergehäuse der Walzentragwelle bewirkten Anstellung der Walzscheiben nicht beeinträchtigt.This form of training of the rolling stand according to the invention allows the Setting a desired rigidity of the roll stand, the small adjustment stroke of the elastic actuator Adjustment kinematics of the eccentric bearing housing of the roller support shaft caused adjustment of the rolling disks not affected.
Wie die Erfindung weiter vorsieht, kann das Stellglied ein positions- und kraftregelbares Kolben-Zylinder-Aggregat sein, das neben der Einstellung der gewünschten Steifigkeit des Walzgerüstes auch über bekannte Regeleinrichtungen eine präzise Korrektur des jeweiligen Walzspalts zwischen den Walzscheiben erlaubt. Die Schwenk- bzw. Neigeachse der Hebelschwinge kann, wie die Erfindung weiter vorsieht, in Richtung der Längsmittenachse der Walzentragwelle längsverstell- und festlegbar angeordnet sein. Diese Verstellbarkeit der Längsmittenachse macht eine genaue Einstellung des von den beiden Walzscheiben gebildeten Walzkalibers auf die Walzmitte möglich. Die Hebelschwinge kann auch als einendig in das Getriebegehäuse längsverschiebbar eingespannter Federstab ausgebildet sein. Wie die Erfindung weiter vorsieht, kann die Schwenk- oder Neigeachse der Hebelschwinge bzw. des Federstabes als Exzenterlager ausgebildet sein. Diese Ausbildung erlaubt ebenfalls eine vorgespannte elastische Abstützung mit Mittenkorrektur der Neigeachse des Federstabes. As the invention further provides, the actuator can be a positionally and force-controllable piston-cylinder unit, which besides the setting of the desired rigidity of the roll stand too Precise correction of the respective via known control devices Roll gap allowed between the rolling disks. The swivel or Tilt axis of the lever rocker can, as the invention further provides longitudinally adjustable in the direction of the longitudinal center axis of the roller supporting shaft and be arranged to be fixable. This adjustability of the Longitudinal center axis makes an exact adjustment of that of the two Roll discs formed rolling caliber possible on the center of the roll. The Lever rocker can also be longitudinally displaceable as one end in the gear housing clamped spring rod be formed. As the Invention further provides the pan or tilt axis of the Lever rocker or the spring rod designed as an eccentric bearing his. This training also allows a prestressed elastic Support with center correction of the tilt axis of the spring bar.
