Description

Einrichtung zur Herstellung der Teilkammern von Wasserrohrkesseln in Wellenform. Zusatz zur Patent 373 279. Die Erfindung bezieht sich auf solche Einrichtungen zur Herstellung der Teilkammern von Wasserrohrkesseln in Wellenform, die aus einem in die Teilkammern vor dem Biegen eingeführten mehrteiligen Kern nach Patent 373 279 bestehen, und bezweckt, die Herstellung dieser Kerne ohne Beeinträchtigung ihrer Brauchbarkeit zu vereinfachen.Device for producing the sub-chambers of water tube boilers in wave form. Addendum to Patent 373,279. The invention relates to such Equipment for the production of the sub-chambers of water tube boilers in wave form, from a multi-part core introduced into the sub-chambers prior to bending Patent 373,279 exist, and the aim is to manufacture these cores without impairment to simplify their usability.

Auf der Zeichnung ist ein Ausführungsbeispiel des Erfindungsgegenstandes dargestellt, und zwar zeigt die Abbildung eine fertig gebogene Teilkammer mit Kern in einem senkrecht zu den wellenförmigen, Mantelflächen der Kanum.er gelegenen Längsschnitt.The drawing shows an embodiment of the subject matter of the invention shown, namely the figure shows a finished bent sub-chamber with a core in a longitudinal section perpendicular to the wavy, lateral surfaces of the canals.

Der Kern der Teilkammer A besteht in bekannter Weise aus einer größeren Anzahl von Platten Bi, B2, B3, welche durch den Dorn C zusammengehalten sind.The core of the sub-chamber A consists in a known manner of a larger number of plates Bi, B2, B3 which are held together by the mandrel C.

Wie aus der Zeichnung ersichtlich, sind zwischen je zwei Platten einer Wellung (z. B. Bi und B2) Zwischenlagen E angeordnet, die aus nachgiebigem Werkstoff, z. B. Pappe, bestehen. Durch die Anordnung der Zwischenlagen wird der Vorteil erreicht, daß die, durch Gießen o. dgl. hergestellten Platten an den einander zugekehrten Flächen nicht bearbeitet zu werden brauchen.As can be seen from the drawing, there is one between each two plates Corrugation (e.g. Bi and B2) intermediate layers E are arranged, which are made of flexible material, z. B. cardboard exist. The arrangement of the intermediate layers has the advantage of that the, by casting o. The like. Manufactured plates on the facing each other Surfaces do not need to be processed.

Eine Ungenauigkeit der Kernform kann. nämlich durch Fehlen der genauen Bearbeitung nicht entstehen, weil sich durch genügend starkes Anziehen des Dornes D die Zwischenlagen so stark zusammenpressen lassen, daß der richtige gegenseitige Abstand: der Platten gewahrt bleibt.An inaccuracy of the core shape can. namely due to the lack of the exact Machining does not arise because the mandrel is tightened sufficiently D let the intermediate layers press together so strongly that the correct mutual Distance: the plates are preserved.

. Die Herstellung des Kenles wird also wesentlich vereinfacht und entsprechend Verbilligt.. The production of the kenle is thus considerably simplified and cheaper accordingly.
