Description
Die Erfindung betrifft ein Herstellungsverfahren für runde Endverschlüsse von Vierkantkammern, die aus zwei rinnenförmigen Längshälften zusammengeschweißt sind.The invention relates to a manufacturing method for round terminations of square chambers, which are welded together from two channel-shaped longitudinal halves are.
Es ist im Dampfkesselbau allgemein bekannt und häufig zur Anwendung gekommen, die Endverschlüsse von Vierkantkammern rund auszuführen, um Material und Arbeit zu sparen und um den Anschluß von normalen Rohren zu vereinfachen. Dies geschah bisher - unabhängig vom Herstellungsverfahren der Kammern selbst - durch örtliche Warmverformung (Kumpeln), erforderte aber einen erheblichen Aufwand an Arbeit und Vorrichtungen.It is well known in steam boiler construction and is often used come to execute the terminations of square chambers round to material and To save labor and to simplify the connection of normal pipes. this happened so far - regardless of the manufacturing process of the chambers themselves - by local Hot deformation (mate), but required a significant amount of work and Devices.
Demgegenüber ermöglicht es die Erfindung, die runde Ausführung der Kammerenden bereits mit dem Herstellungsvorgang der Kammern selbst in der Weise zu verbinden, daß die zum Pressen bzw. Schmieden der rinnenfärmigen Kammerhälften verwendeten Gesenke von vornherein mit zweckentsprechenden, halbzylindrisch auslaufenden Enden versehen werden, wodurch jede Mehrarbeit entfällt. Die Stirnseiten der Kammer werden dann - nach Fertigstellung der Längsschweißnähte -wie bei allen anderen Kammern mittels Rundschweiße durch flache oder gewölbte Runddeckel verschlossen, deren letztere gegebenenfalls auch als eine Art Übergangsstutzen für Anschlußrohre ausgebildet sein können. Das Verfahren kann daher mit besonderem Vorteil auch bei sogenannten Sägekammern Verwendung finden, ist aber grundsätzlich an keine bestimmte Querschnittsform gebunden. In der Zeichnung ist die Erfindung in einem Ausführungsbeispiel dargestellt.In contrast, the invention allows the round design of the Chamber ends in the same way as the chambers are manufactured to connect that for pressing or forging the gutter-shaped chamber halves used dies from the outset with appropriate, semicylindrical tapering Ends are provided, which eliminates any additional work. The front sides of the chamber are then - after completion of the longitudinal welds - as with all other chambers closed by means of circular welding through flat or curved round lids, the latter possibly also designed as a kind of transition piece for connecting pipes could be. The method can therefore also be used with particular advantage in so-called Saw chambers are used, but in principle there is no specific cross-sectional shape bound. In the drawing, the invention is shown in one embodiment.
Abb. i zeigt ein Ausführungsbeispiel der normal verwendeten Kammerenden in Vierkantform.Fig. I shows an embodiment of the normally used chamber ends in square shape.
Die erfindungsgemäße Ausführung ist in den Abb. 2 und 3 dargestellt.The embodiment according to the invention is shown in FIGS.
Abb. 2 zeigt die runden Enden mit gewölbtem Deckel und Abb. 3 einen Übergangsstutzen für Rohranschluß. Die Kammerenden 16 werden durch die Verformung im Gesenk zu runden Rohren 17, an welche gewölbte Deckel 1ä angeschweißt werden. An solchen Enden, die mit einem Anschluß versehen werden, sind die gewölbten Deckel i8 beispielsweise durch Herausziehen zu Übergangsstutzen ig ausgebildet.Fig. 2 shows the round ends with a curved lid and Fig. 3 shows one Transition piece for pipe connection. The chamber ends 16 are due to the deformation in the die to round tubes 17, to which arched covers 1ä are welded. At those ends, which are provided with a connection, are the domed covers i8 formed, for example, by pulling out to transition pieces ig.
