DEUTSCHESGERMAN Die vorliegende Erfindung betrifft ein Verfahren zum Herstellen von Vormaterial für Stoßbänke durch Stranggießen von Rohrabschnitten.The present invention relates to a method for producing raw material for bumper benches Continuous casting of pipe sections. Nach dem Stand der Technik ist es bekannt, Stränge nach dem Austritt aus der Gießform zu verformen, bevor sie abgelängt werden. Gemäß der Erfindung wird der Strang in gewissen regelmäßigen Abständen im Querschnitt so eingeschnürt, daß diese Einschnürung eine spätere Kümpelung der Rohrabschnitte erübrigt. Dieses Einschnüren der Teilstücke findet also im Sinne der Erfindung bereits während des Austrittes des Rohrstranges aus der Gießvorrichtung oder unmittelbar danach mittels entsprechend angeordneter Matrizenringe kontinuierlich statt.According to the prior art, it is known to deform strands after exiting the casting mold, before they are cut to length. According to the invention, the strand is at certain regular intervals constricted in cross-section so that this constriction causes later dishing of the pipe sections unnecessary. This constriction of the sections takes place in the sense of the invention already during the exit of the pipe string from the casting device or immediately thereafter by means of appropriately arranged Die rings take place continuously. Die Einschnürung wird in Ausführung der Erfindung jeweils in Doppellänge der gewünschten Endteilstücke vorgenommen. Man erhält demgemäß an beiden Enden eingeschnürte Doppellängen. Diese werden erfindungsgemäß ihrerseits wieder in der Mitte geteilt, so daß daraus jeweils zwei Endstücke in der ao gewünschten Form und Länge entfallen.In the embodiment of the invention, the constriction is double the length of the desired end sections performed. Accordingly, constricted double lengths are obtained at both ends. These are in turn divided in the middle according to the invention, so that therefrom two end pieces in the ao desired shape and length are omitted. Der Vorteil der Erfindung liegt darin, daß, abgesehen von dem Vorteil der kontinuierlichen Arbeitsweise, der notwendige Abtrennvorgang mit der erforderlichen Einschnürarbeit gekuppelt wird, die sonst auf dem besonderen hierfür üblichen Stauch- oder Einziehpressen in getrenntem Arbeitsgang und erneuter Erwärmung vorgenommen werden muß.The advantage of the invention is that, apart from the advantage of the continuous mode of operation, the necessary separation process is coupled with the necessary constriction work, which otherwise on the special upsetting or drawing-in press used for this purpose in a separate operation and again Heating must be made. Die Zeichnung erläutert den vorbeschriebenen Vorgang beispielsweise.The drawing explains the above process, for example. Der aas der Stranggußanlage austretende Rohrstrang α wird durch die zwei- oder mehrteiligen Ringmatrizen f, die ihrerseits in an sich bekannter Weise in Pfeilrichtung bewegt bzw. druckgesteuert werden können, eingeschnürt. Die Einschnürung kann nach Erfordernissen des späteren Stoßvorganges (in der entsprechenden Stoßbank) beliebig bis zur völligen Schließung des Ringquerschnittes erfolgen. Sie erfolgt kontinuierlich in der doppelten Länge der gewünschten Endrohrhülse. Diese Doppellänge b wird in ebenfalls kontinuierlichem Verfahren durch die Vorrichtung c vom Rohrstrang abgetrennt. Die so erhaltene, an beiden Enden eingeschnürte Rohrhülse wird sodann durch die Abtrennvorrichtung d in die beiden gleich langen Endrohrhülsen e geteilt. Dieser letztere Vorgang kann Verfahren zum Herstellen The pipe string α exiting the continuous casting plant is constricted by the two-part or multi-part ring matrices f, which in turn can be moved or pressure-controlled in a manner known per se in the direction of the arrow. The constriction can take place as required by the later impact process (in the corresponding impact bench) up to the complete closure of the ring cross-section. It takes place continuously in twice the length of the desired tailpipe sleeve. This double length b is separated from the pipe string by the device c in a likewise continuous process. The pipe sleeve thus obtained, constricted at both ends, is then divided by the separating device d into the two end pipe sleeves e of the same length. This latter operation can be methods of manufacture von Vormaterial für Stoßbänkeof raw material for bumper benches durch Stranggießen von Rohrabschnittenby continuous casting of pipe sections
