Patentiert im Deutschen Reiche vom 26. März 1913 ab.Patented in the German Empire on March 26, 1913.
Die Erfindung betrifft ein Verfahren und eine Vorrichtung zur Herstellung von Rohren und profilierten Hohlleisten aus Blechplatten oder -streifen mit Hilfe eines zwischen den Fertigwalzen angeordneten Domes und besteht darin, daß der Dorn beweglich angeordnet ist und der Dornkopf, welcher der Form der zu erzeugenden Hohlleisten entsprechend gestaltet und auswechselbar ist, zwecks Erzeugung einesThe invention relates to a method and a device for producing pipes and profiled hollow strips made of sheet metal plates or strips with the help of a between the Finishing rollers arranged domes and consists in that the mandrel is movably arranged and the mandrel head, which is designed to match the shape of the hollow strips to be produced and is interchangeable to produce a

Ist der Dorn fest zwischen den beiden Fertigwalzen angeordnet, so wird das zu erzeugende Profil nicht scharf ausgeprägt.

Die Entfernung wird vielmehr je nachIf the mandrel is firmly arranged between the two finishing rolls, the one to be produced will be Profile not sharply defined. In particular, it is not possible to have an absolutely reliable one Accuracy for removing the edges. or to achieve legs of the profile from each other. Rather, the distance will vary depending on

Die zur Ausführung des Verfahrens dienende Vorrichtung ist auf der Zeichnung dargestellt, und zwar zeigen: Fig. ι die Vorrichtung im teilweisen Längsschnitt, Fig. 2 den Dorn vonThe device used to carry out the process is shown in the drawing, namely show: Fig. ι the device in partial longitudinal section, Fig. 2 the mandrel of

Der Blechstreifen geht zunächst durch die beiden Vorwalzen b (Fig. 1), zwischen denen der Dorn α aufgehängt ist, und wird hier vorgebogen. Je nach der Art des Profils geht er dann durch ein oder mehrere Walzenpaare c und erhält das Endprofil zwischen den Fertigwalzen d, zwischen denen sich der Kopf e des Domes α befindet.The sheet metal strip first goes through the two pre-rollers b (Fig. 1), between which the mandrel α is suspended, and is pre-bent here. Depending on the type of profile, it then goes through one or more pairs of rollers c and receives the final profile between the finishing rollers d, between which the head e of the dome α is located.
Der Kopf e des Domes α wird, wie schon erwähnt, mehr oder weniger fest gegen die untere Fertigwalze d gedrückt, und zwar kann dies dadurch geschehen, daß die obere Walze des letzten Paares der Walzen c auf den Dorn a drückt (Fig. 3 und 4). Der Druck auf den Dorn kann durch Einstellen der letzten oberen Walze c geregelt werden, und je nach seiner Stärke wird der Druckknopf e mehr oder weniger fest gegen die untere Fertigwalze d ge- drückt, so daß ein Profil mit weiterer oder engerer Öffnung entsteht.The head e of the dome α is, as already mentioned, pressed more or less firmly against the lower finishing roller d , and this can be done by the fact that the upper roller of the last pair of rollers c presses on the mandrel a (Fig. 3 and 4). The pressure on the mandrel can be regulated by adjusting the last upper roller c , and depending on its strength, the push button e is pressed more or less firmly against the lower finishing roller d, so that a profile with a wider or narrower opening is created.
In der gezeigten Ausführungsform drückt die obere Druckwalze c mit einem Wulstring g auf eine Gleitrolle f, die in einer Aussparung der Dornstange α angeordnet ist.In the embodiment shown, the upper pressure roller c presses with a bead ring g on a sliding roller f, which is arranged in a recess in the mandrel bar α .
Fig. 5 zeigt die Fertigwalzen d mit dem dazwischen angeordneten Profilkopf e des Domes im Querschnitt. Der hier dargestellte Dorn-Fig. 5 shows the finishing rolls d with the interposed profile head e of the dome in cross section. The thorn shown here
