Description
Es ist eine Vorrichtung bekanntgeworden, mit der geschweißte Rohre aus mit ihren Enden- stumpf aneinandergesrihweißten Röhrenstreifen derart hergestellt wenden, daß der im kontinuierlich fortbewegten, endlosen Streifen befindliche Grat bzw. Restgrat der die Streifenenden verbindenden Schweißnaht eine Schaltvorrichtung betätigt, mit der die Maßnahmen zur Erwärmung und anschließenden VerformungIt has become known a device with the welded pipes from with their Tube strips butt-welded to one another at the ends turn produced in such a way that the continuously moved, endless strip located ridge or residual ridge of the weld joining the strip ends a switching device actuated, with which the measures for heating and subsequent deformation
ίο der Schweißnaht eingeleitet werden. Die Erwärmung
kann mittels Gas oder elektrischer JSnergie
erfolgen. Die Vorrichtung zum Erwärmen wird hydraulisch, pneumatisch oder elektromagnetisch
mit den in Bewegung befindlichen Streifen gekoppelt und dann in Ausgangsstellung zurückgefahren,
während der Streifen mit der vorgewärmten Querschweißnaht die dahinter befindliche, stationär angeordnete
Verformungsvorrichtung durchläuft.
Die vorliegende Erfindung besteht darin, daß dieίο the weld seam can be initiated. The heating can take place by means of gas or electrical energy. The heating device is hydraulically, pneumatically or electromagnetically coupled to the moving strip and then moved back into the starting position, while the strip with the preheated transverse weld seam passes through the stationary deformation device located behind it.
The present invention is that the
ao Heizvorrichtung und die Verformungswerkzeuge aus paarweise angeordneten, zusammenwirkenden Einzelgliedern, z. B. einem Brennerpaar oder zwei gegenüberliegenden Induktionsspulen bzw. einem gegeneinander arbeitenden Hammerpaar oder Druckrollenpaar, bestehen, die auf einem gemeinsamen, quer über die Bandbreite bewegbaren Träger in Gratrichtung hintereinander angebracht sind. Mit dieser Vorrichtung können die Querschweißnähte nach ihrer Schweißung und Entgratung nochmais quer zur Bewegungsrichtung des Streifens fortschreitend auf Verformungstemperatur gebracht und diese vorgewärmten Stellen unmittelbar darauf verformt werden. Dabei wird die für diesen Vorgang erforderliche Wegstrecke des vorwärts bewegten Röhrenstreifens gegenüber den in der Hauptpatentanmeldung angegebenen Mitteln abgekürzt, da beide Vorgänge unmittelbar einander folgen. Außerdem ist die Erzielung einer gleichen Temperatur und Verformung über die gesamte Querschweißnahtlänge gewährleistet.ao heating device and the deformation tools from cooperating arranged in pairs Individual links, e.g. B. a pair of burners or two opposite induction coils or one mutually working pair of hammers or pressure rollers, exist on a common, across the band width movable carrier are attached one behind the other in the ridge direction. With this device, the transverse weld seams can be maize again after they have been welded and deburred progressively brought to deformation temperature transversely to the direction of movement of the strip and these preheated areas are deformed immediately afterwards. This is used for this process required distance of the tubular strip moved forward compared to that in the Main patent application is abbreviated as the two processes are directly related to each other follow. In addition, the achievement of an equal temperature and deformation over the entire Cross weld seam length guaranteed.
Ein Anwendungsbeispiel ist in Abb. 1 und 2 dargestellt. Die Vorrichtung, bestehend aus den Brennern B1 und B2 sowie zwei gegeneinander wirkenden Hämmern M1 und M2, bewegt sich quer zur Vorwärtsbewegung über den Röhrenstreifen S, der die Quernaht QN (Abb. 2) trägt. Die Brenner B1 und· B2 sind dem gegeneinander wirkenden Hammerpaaren M1 und M2 vorgeschaltet und im ganzen zu einer Einheit verbunden. Diese führt die Vorwärmung und Verformung der Querschweißnaht in kürzester Zeit völlig gleichmäßig durch.An application example is shown in Figs. 1 and 2. The device, consisting of the burners B 1 and B 2 as well as two mutually opposing hammers M 1 and M 2 , moves transversely to the forward movement over the tube strip S, which carries the transverse seam QN (Fig. 2). The burners B 1 and B 2 are connected upstream of the opposing pair of hammers M 1 and M 2 and are connected as a whole to form a unit. This carries out the preheating and deformation of the transverse weld seam in the shortest possible time completely evenly.
