Description
Die Erfindung betrifft eine weitere Ausbildung einer Vorrichtung zum Walzenkopfwechsel in kontinuierlich arbeitenden Universal- bzw. Rohrreduzierwalziverken nach Patent 901 526, bei der die Walzenköpfe einzeln; gruppenweise oder gemeinsam aus- und einfahrbar sind. Durch die Einrichtung nach dem Hauptpatent wird bei dem gemeinsamen Aus- und Einfahren der Walzenköpfe aus den Walzgerüsten erheblich an Zeit für den Umbau gewonnen, dennoch ist es umständlich, die seitwärts herausgefahrenen Walzenköpfe mit Hilfe eines Krans einzeln zu tränsportieren und wiederum einzeln neue Walzenköpfe an die Stelle der alten zu setzen, so daß diese dann'wiederum gemeinsam eingefahren werden können.The invention relates to a further embodiment of a device for Roll head change in continuously operating universal or tube reducing mills according to patent 901 526, in which the roller heads individually; in groups or together are extendable and retractable. Through the establishment according to the main patent, the joint extension and retraction of the roll heads from the roll stands Time gained for the conversion, but it is cumbersome to drive out sideways To transport roller heads individually with the help of a crane and again individually to put new roller heads in place of the old ones, so that these then 'again together can be retracted.
Die Erfindung besteht nun. darin, die Vorrichtung nach dem Hauptpatent dadurch sehr wesentlich zu verbessern, daß ein an sich bekanntes Merkmal hinzugefügt wird, nämlich eine parallel zur Walzrichtung vierfahrbare Transportvorrichtung zur Aufnahme sämtlicher ausgebauten und einzubauenden Walzenköpfe. Durch diese Kombination ist es möglich, nicht nur schnellstens die Wafzenköpfe aus den Walzgerüsten herauszufahren bzw. sie einzufahren, sondern auch die alten Walzenköpfe schnellstens aus dem Bereich der Walzgerüste herauszubringen und neue für den Einbau in die Bereitschaftsstellung zu stellen.The invention now exists. therein, the device according to the main patent to be improved very substantially by adding a feature known per se is, namely a four-wheeled transport device parallel to the rolling direction for Acceptance of all dismantled and to be installed roller heads. Through this combination it is possible not only to move the die heads out of the roll stands as quickly as possible or retract them, but also get the old roller heads out of the area as quickly as possible of the rolling stands and new ones for installation in the ready position to deliver.
Der Betrieb kontinuierlicher Walzwerke wird dadurch wesentlich günstiger gestaltet.This makes the operation of continuous rolling mills much cheaper designed.
Der Gegenstand der Erfindung wird durch die Abbildungen veranschaulicht, und zwar beispielsweise an einem Maßwalzwerk mit sechs Walzenköpfen und zwei Walzen je Walzenkopf. Dabei bedeuten Abb. i die Ansicht, Abb. 2 und q. Draufsichten des Walzwerks mit den erfindungsgemäßen Vorrichtungen, während Abb. 3 die Seitenansicht des Wagens mit zwei Walzenköpfen zeigt.The object of the invention is illustrated by the figures, for example on a sizing mill with six roller heads and two rollers per roller head. Fig. I mean the view, Fig. 2 and q. Top views of the Rolling mill with the devices according to the invention, while Fig. 3 shows the side view of the carriage with two roller heads shows.
Der Hauptantriebsmotor i treibt über eine Kupplung 2 und ein Vorgelege 3 die Walzen 4 und 4', die sich in den hintereinanderliegenden Walzenköpfen 5 befinden. Die Walzen 4 und 4' sind mittels Klauenkupplungen 6 und 6' mit dem Betrieb verbunden. Die Fixiervorrichtungen 7 halten die Walzenköpfe in ihrer Arbeitsstellung. Nach Lösen der Kupplungen 6 und 6' der Fixiervorrichtung 7 -,verden mit Hilfe.der ortsfesten Auszieh- und Einschiebevorrichtung 8 die Walzenköpfe 5 aus dem Walzwerksbett g herausgezogen und auf den Wagen io geschoben, der in bzw., entgegen der Walzrichtung vierfahrbar zwischen den Anschlägen 14 und 14' angeordnet ist. Abb. 2 zeigt die eine, Abb.4 die andere Endstellung des Wagens. Beim Ausziehen der Walzenköpfe steht der Wagen io in der Stellung gemäß Abb. 2. Dabei sind auf dem vorderen Teil des Wagens bereits die neu einzusetzenden Walzenköpfe 5 auf die Transportflächen 13 des Wagens aufgesetzt. Nach "dein Ausziehen fährt der Wagen io in die Stellung gemäß Abb. 4.The main drive motor i drives via a clutch 2 and a countershaft 3 the rollers 4 and 4 ', which are located in the roller heads 5 lying one behind the other. The rollers 4 and 4 'are connected to the plant by means of dog clutches 6 and 6'. The fixing devices 7 hold the roller heads in their working position. To Loosen the couplings 6 and 6 'of the fixing device 7 -, verden with the help of the stationary Pull-out and push-in device 8, the roller heads 5 pulled out of the rolling mill bed g and pushed onto the wagon io, which can be moved in or against the rolling direction is arranged between the stops 14 and 14 '. Fig. 2 shows one, Fig.4 the other end position of the carriage. The carriage comes to a standstill when the roller heads are pulled out io in the position shown in Fig. 2. There are already on the front part of the carriage the new roller heads 5 to be used placed on the transport surfaces 13 of the carriage. After you have pulled out the carriage moves to the position shown in Fig. 4.
Daraufhin werden die neuen Walzenköpfe gemeinsam mit Hilfe der Vorrichtung 8 in das Walzwerksbett g eingeschoben. Der Hilfsmotor i i treibt über die Kupplung 12 das Walzwerk mit kleiner Drehzahl in der Zeit des Walzenwechsels.Thereupon the new roller heads are together with the help of the device 8 pushed into the rolling mill bed g. The auxiliary motor i i drives via the clutch 12 the rolling mill at low speed during the roll change.
