Description

Die Erfindung löst die Aufgabe, während des Stranggießens von Stahl die Abtrennung der einzelnen Walzblöcke durch eine Brennschneidmaschine vorzunehmen. Da sich der Gießstrang ständig abwärts bewegt, ist es erforderlich, daß auch die Brennschneidmaschine diese Abwärtsbewegung stetig mitmacht. Eine genaue synchrone Bewegung von Strang und Maschine ist jedoch nur schwierig zu erreichen, weil die Maschine auch den Abweichungen des Stabes von der geradlinigen senkrechten Bewegung, die beim Stranggießen unvermeidbar entstehen, folgen muß, um Klemmungen der Maschine und einen Fehlschnitt des Brenners zu vermeiden. Deshalb wird die Bewegung der Brennschneidmaschine nach der Erfindung durch den Strang selbst geführt.The invention solves the problem during the continuous casting of steel make the separation of the individual billets by a flame cutting machine. Since the cast strand is constantly moving downwards, it is necessary that the Torch cutting machine constantly participates in this downward movement. An exact synchronous However, movement of the strand and machine is difficult to achieve because the Machine also the deviations of the rod from the straight, vertical movement, which inevitably arise during continuous casting, must follow to prevent the machine from jamming and to avoid a wrong cut of the torch. Therefore the movement of the cutting machine guided according to the invention by the strand itself.

Eine Brennschneidmaschine, die allen Ungenauigkeiten der Strangbewegung Rechnung trägt, ist in der Zeichnung dargestellt.A flame cutting machine, all inaccuracies in the strand movement Is shown in the drawing.

Fig. i zeigt eine Vorderansicht der Maschine, während Fig. 2 eine Aufsicht darstellt.Fig. I shows a front view of the machine, while Fig. 2 shows a Represents supervision.

Zwei senkrecht stehende Säulen i und 2 tragen das Maschinengerüst, bestehend aus den beiden Querschienen 3 und 4, die an Traversen 5 und 6 befestigt sind, die sich an den Säulen i und 2 auf und. ab bewegen können. Auf den Traversen 3 und .1. bewegt sich hängend der Unterw alten 7 eines umgedrehten Kreuzwagensystems auf den Rollen 8, 9, io und ii. Quer zu der Bewegungsrichtung des Unterwagens 7 läuft der Oberwagen 12 auf den Rollen 13, 14, 15 und 16. An dem Oberwagen, der aus konstruktiven Gründen unter dem Unterwagen hängt, befinden sich zwei einstellbare Distanzbolzen 17 und 18, die den Oberwagen in der richtigen Stellung zu dem Strang i9 halten. In der Querrichtung wird die Kupplung durch eine Preßluftspanneinrichtung bekannter Bauart mit dem Zylinder 2o und einem Scherengestänge 2i, 22 sowie zwei Klemmbacken 23, 24 vorgenommen. An dem Oberwagen 12 befindet sich der Schneidbrenner 25, der alle Strangbewegungen mitmacht.Two vertical columns i and 2 support the machine frame, consisting of the two cross rails 3 and 4, which are attached to traverses 5 and 6 are located on pillars i and 2 on and. starting to move. On the trusses 3 and .1. moves hanging from the lower arm 7 of an upside-down cross carriage system on reels 8, 9, io and ii. Transverse to the direction of movement of the undercarriage 7 the upper carriage 12 runs on the rollers 13, 14, 15 and 16. On the upper carriage, the hanging under the undercarriage for structural reasons, there are two adjustable ones Spacer bolts 17 and 18 that keep the superstructure in the correct position on the string hold i9. In the transverse direction, the coupling is held by a compressed air clamping device known design with the cylinder 2o and a scissor linkage 2i, 22 and two Clamping jaws 23, 24 made. The cutting torch is located on the upper carriage 12 25, who goes along with all strand movements.

Im Ausführungsbeispiel ist der Brenner auf einem Support 26 aufgesetzt, der auf der Schiene 27 verschiebbar ist.In the exemplary embodiment, the burner is placed on a support 26, which can be moved on the rail 27.

Es ist selbstverständlich möglich, den Brenner statt auf eine solche einfache Vorrichtung beim Schneiden komplizierterer Teile auf ein zweites Kreuzwagensystem aufzusetzen. Ebenso ist es möglich, die Bewegung des Unterwagens 7 durch pendelndes Aufhängen der Traversen 3 und 4 und unter Verzicht auf die Lagerung auf den Rollen 8 bis ii zu ersetzen.It is of course possible to use the burner instead of one simple device when cutting more complicated parts on a second cross carriage system put on. It is also possible to control the movement of the undercarriage 7 by swinging Suspending the trusses 3 and 4 and dispensing with storage on the rollers Replace 8 through ii.

Die ganze Maschine besitzt ein in der Zeichnung nicht dargestelltes Gegengewicht, so daß sie sich leicht auf und ab bewegen läßt, wenn sie nicht mit dem Gießstrang gekuppelt ist.The whole machine has one that is not shown in the drawing Counterweight so that it can be easily moved up and down when not with it is coupled to the cast strand.
