Abstract
Description
Die Erfindung betrifft einen ständerlosen Walzentragrahmen für zweiseitig in Lagereinbaustücken gelagerte Walzenpaare, der in einen, die Antriebsübertragungs- und Anstelleinrichtungen für die Walzen aufnehmenden, einseitig offenen Ständer ein- und ausbringbar ist.The invention relates to a stand-free roller support frame for double-sided in bearing chocks mounted roller pairs, which in one, the drive transmission and adjustment devices for the roll-receiving, one-sided open stand can be brought in and out.
Es sind zahlreiche Ausbildungsformen von Walzgerüstanordnungen bekannt geworden, bei denen Duo-Walzgerüste in, einseitig offene Ständer, sog. C-Ständer eingeschoben, arretiert und mit, in dem Ständer fest angeordneten Antriebselementen verbunden werden. Bei den Walzgerüsten handelte es sich entweder um vollständige Trägergerüste oder auch um, die Walzenpaare tragende, kassettenartige Gerüste. Die Trägergerüste sind meist mit eigenen, in ihrem Gerüst angeordneten Anstelleinrichtungen ausgestattet, die, nach Einbringen des Gerüstes in den Ständer mit entsprechenden Steuerelementen verbunden werden (vgl. DE-OS 1 527 674 und 2 907 398). Es wurde aber auch schon vorgeschlagen, die Anstelleinrichtungen nicht in dem Trägergerüst oder der Gerüst-Kassette, sondern in dem ortsfesten Ständer selbst anzuordnen, die dann mit den Lagereinbaustücken der Walzen des eingefahrenen Gerüstes bzw. der Gerüst-Kassette verbunden wurden (DE-PS 3 132 339). Numerous forms of training of mill stand arrangements have become known, in which duo mill stands in, one-sided open stands, so-called C-stands inserted, locked and with, in the stand fixedly arranged drive elements get connected. The roll stands were either complete carrier stands or around, the roller pairs carrying, cassette-like Scaffolding. The support frames are usually with their own, arranged in their scaffolding Equipped equipment, which, after the scaffolding has been brought in the stand can be connected to appropriate controls (see DE-OS 1 527 674 and 2 907 398). However, the adjustment devices have also already been proposed not in the support frame or the frame cassette, but in to arrange the stationary stand itself, which then with the bearing chocks connected to the rollers of the retracted stand or the stand cassette were (DE-PS 3 132 339).
Diese bekannten Ausbildungsformen erfordern durchweg einen erheblichen Herstellungsaufwand und ihr Betrieb ist bedienungs- und wartungsintensiv.These known forms of training consistently require considerable manufacturing effort and their operation is operation and maintenance intensive.
Der Erfindung liegt die Aufgabe zugrunde, einen ständerlosen Walzentragrahmen zu schaffen, der aus wenigen, modulartigen, mit geringem Herstellungsaufwand herzustellenden, gegeneinander austauschbaren, wenig Wartung erfordernden Bauteilen besteht.The invention has for its object a stand-free roller support frame to create the few, modular, with little manufacturing effort to be manufactured, interchangeable, requiring little maintenance Components.
Ausgehend von einem bekannten Vorschlag (EP 639 495 A2), nach dem die Walzen eines Duo-Walzenpaares eines ständerlosen Walzentragrahmens in Lagereinbaustücken lagern, die, in tragrahmenfesten Führungen gegeneinander und voneinander weg verschiebbar geführt, mittels eines, durch sie hindurchgeführten Gewindespindelpaares miteinander verbunden sind, und das Gewindespindelpaar, außenangetrieben, die Anstellbewegungen der Lagereinbaustücke bewirkt, wird dieser Aufgabe dadurch gelöst, daß der Walzentragrahmen aus einem Kastenelement mit Ein- und Ausgangs-Durchgängen, Führungen für das Walzgut und an dem Kastenelement angeordneten Halte- und Führungselementen für die Lagereinbau-Paare jeder der Duo-Walzen besteht, wobei wie die Erfindung weiter vorsieht, die beiden Lagereinbaustücke der einen, als auch der anderen Walze des Duo-Walzenpaares bei, in den Ständer eingefahrenem Walzentragrahmen, jeweils von je einer Walzenanstelleinrichtung beaufschlagbar sind. Die Halte- und Führungselemente für die Lagereinbaustück-Paare können erfindungsgemäß aus, in Bohrungen in den Lagereinbaustücken geführten Zylinderbolzenpaaren bestehen, die von, seitlich an dem Kastenelement angeordneten Kragansätzen gehalten, in den Bohrungen, stirnseitig gegen die Lagereinbaustücke federabgestützt sein. An beiden Seitenwänden des Kastenelementes können vorteilhaft Anschläge angeordnet werden, die bei in den Ständer eingefahrenem Walzentragrahmen von, in den einander gegenüberliegenden Seitenwänden des Ständers angeordneten Riegelelementen klemmbeaufschlagbar sind. An seiner, dem Ständer zugewandten Vorderseite kann der Walzentragrahmen Medienkuppelelemente aufweisen. Die Walzen des Duo-Walzenpaares können jeweils eine Kuppelbohrung für das Einführen eines Kuppelbolzen mit Polygonquerschnitt aufweisen. Die Stellbewegungen der, die Lagereinbaustücke der Walzen beaufschlagenden Anstelleinrichtungen können über meß- und festwertbeeinflußte Recheneinrichtungen steuerbar sein.Based on a known proposal (EP 639 495 A2), according to which the rollers a pair of duo-rollers of a stand-free roller support frame in bearing chocks store the, against each other in fixed guides guided displaceably away from each other by means of a guided through them Lead screw pair are connected to each other, and the lead screw pair, externally driven, the adjustment movements of the bearing chocks causes This object achieved in that the roller support frame from a box element with entry and exit passages, guides for the rolling stock and arranged on the box element holding and guiding elements for the Bearing installation pairs of each of the duo rollers consists of, as the invention continues provides for the two bearing chocks of one and the other roller the pair of duo rollers with the roller support frame retracted into the stand, can each be acted upon by a roller adjusting device. The holding and According to the invention, guide elements for the bearing insert pairs can consist of consist of pairs of cylinder bolts guided in bores in the bearing chocks, held by cantilever lugs arranged on the side of the box element, in the bores, spring-supported at the end against the bearing chocks his. Stops can advantageously be provided on both side walls of the box element be arranged with the roller support frame retracted into the stand from, arranged in the opposite side walls of the stand Bolt elements are clampable. On his, facing the stand The front of the roller support frame can have media coupling elements. The rollers of the pair of duo rollers can each have a dome bore for inserting a dome bolt with a polygonal cross-section. The Adjusting movements of the adjusting devices that act on the bearing chocks of the rollers can via measuring and fixed value-influenced computing devices be controllable.
Diese erfindungsgegenständliche Ausbildung des Walzentragrahmens führt zu einfachen, kompakten Walzmodulen mit integrierten Walzgutführungen, die mit niedrigen Kosten herzustellen sind und sich ohne Änderungen zu Mehrgerüstanordnungen zusammenstellen lassen, bei denen die Gerüstzahlen veränderbar und die einzelnen Gerüste gegeneinander austauschbar sind. Vorzugsweise können in diesen Gerüsten kleine, einkalibrige Walzen mit einfachen Lagern, deren Halterung axial spielfrei sein kann, verwendet werden. Da das Walzmodul keine eigenen Anstellvorrichtungen aufweist und seine Lagereinbaustücke von, in dem Ständer befindlichen Anstellvorrichtungen beaufschlagbar sind, lässt sich insb. bei Verwendung hydraulisch betätigten und gesteuerten Anstellvorrichtungen eine Walzgerüstanordnung zusammenstellen, bei der Walzkraftmessungen über die Hydraulik der Anstellvorrichtung, Nullen und Kalibrieren und mittels der meß- und festwertbeeinflußten Recheneinrichtungen ein Presetting der Walzen z. B. für das Präzisionswalzen ermöglichen und weiter erlaubt eine solche Anstellsteuerung die Lösung von Problemen, wie Anstellwiederholungen, Speicherung der Anstelldaten ebenso können veränderliche Überlastsicherungen vorgesehen werden. Der Polygonquerschnitt der Kuppelbohrung der Walzen und des Kuppelbolzens erlaubt dabei eine schnelle, drehfeste und ebenso schnell lösbare Kupplung der Walzen mit den Antriebsspindeln und der einfache Aufbau der Walzmodule läßt es zu, diese ggfs. im Bereich der Walzenstraße umzubauen und einzustellen.This inventive design of the roller support frame leads to simple, compact rolling modules with integrated rolling stock guides that work with can be produced at low cost and without changes to multi-scaffold arrangements let put together, where the scaffolding numbers can be changed and the individual scaffolds are interchangeable. Preferably can in these stands small, single-caliber rolls with simple bearings, the Bracket axially free of play can be used. Since the rolling module is none has its own adjusting devices and its bearing chocks from where Stand located adjustment devices can be acted upon, in particular Use hydraulically operated and controlled adjusting devices Assemble the rolling stand arrangement in which rolling force measurements are made using the Hydraulics of the adjusting device, zeroing and calibration and by means of the measuring and computing devices influenced by a fixed value presetting the rollers z. B. for that Precision rollers enable and further such an adjustment control allows Solving problems such as recurring jobs, saving the job data variable overload protection devices can also be provided. The polygon cross section the dome bore of the rollers and the dome bolt allowed thereby a quick, non-rotatable and just as quickly releasable coupling of the rollers with the drive spindles and the simple structure of the rolling modules, it allows if necessary, convert and adjust them in the area of the roller mill.

Aus Figur 5 geht das Zusammenwirken des Walzentragrahmens WTR mit dem Ständer ST hervor. Die nicht dargestellte Walzenstraße wurde vorab stillgesetzt, die Medienkupplungen gelöst und die (in Fig. 3 dargestellten) Anschläge AS und Riegelelemente RE gelöst. Anschließend wurde ein auszuwechselnder Walzentragrahmen mit Hilfe des, von der Ausziehvorrichtung AV betätigten Gerüstwechselwagens GF aus dem Ständer ST herausgezogen und abtransportiert. Anschließend fährt der, den neuen Walzentragrahmen WTR tragende Gerüstwechselwagen GW quer zur Walzrichtung in den Ständer ST in die dargestellte Position ein, in der Ständer ST und Walzentragrahmen WTR mit den erwähnten Anschlägen AS und Riegelelementen RE verriegelt und gleichzeitig (nicht dargestellt) die Medienkupplungen an der Vorderseite des Walzentragrahmens WTR mit den Versorgungsleitungen im Ständer ST verbunden werden. Mit der Einfahrbewegung werden die Kuppelbolzen BK (vgl. Fig. 4) in die Kuppelbohrungen KB der Walzen W eingebracht und nach Absenken der Schienen SCH (vgl. Fig. 3) die Anstellkolben AK der in dem Ständer ST angeordneten Anstellvorrichtungen gegen die Lagereinbaustücke LES der Walzen W bewegt. Nach Zurückfahren des Gerüstwechselwagens GW werden die Walzen W mit Hilfe der, die Lagereinbaustükke LES beaufschlagenden Anstellkolben AK der Anstellvorrichtung in ihre Nullposition eingebracht und anschließend die vorgegebene Walzspaltgröße eingestellt.FIG. 5 shows the interaction of the roll support frame WTR with the Stand ST stands out. The roller mill, not shown, was shut down in advance, the media couplings released and the stops (shown in Fig. 3) AS and Bolt elements RE released. Then a roller support frame to be replaced with the help of the scaffold changing trolley operated by the pull-out device AV GF pulled out of the stand ST and transported away. Subsequently the scaffold changing carriage carrying the new WTR roller support frame drives GW transverse to the rolling direction in the stand ST in the position shown one, in the stand ST and roller support frame WTR with the mentioned stops AS and locking elements RE locked and at the same time (not shown) the Media couplings on the front of the WTR roller support frame with the supply lines be connected in the stand ST. With the entry movement the coupling bolts BK (see FIG. 4) into the coupling bores KB of the rollers W introduced and after lowering the rails SCH (see. Fig. 3) the adjusting pistons AK of the adjusting devices arranged in the stator ST against the bearing chocks LES of the rollers W moves. After the scaffold changing vehicle has returned GW the rollers W with the help of the bearing chocks LES acting on the adjusting piston AK of the adjusting device in its zero position introduced and then set the predetermined roll gap size.
Die Ausbildung nach Figur 6 entspricht der nach Figur 5 mit der Maßgabe, daß hier der Ständer ST für den Walzentragrahmen WTR mit einem Vertikalwalzenpaar W bestimmt ist. Der, die Antriebsspindeln AS und ihren Anstellmotor AM aufnehmende Ständer ST ist hier, mit nach unten gerichteter Einfahröffnung vertikal verfahrbar an einem Tragsockel TS geführt.
