Description

Die Erfindung bezieht sich auf eine Vervollkommnung der Vorrichtung zum Ausbeulen und Richten von unrund gewordenen Wetterlutten, dünnwandigen Rohren u. dgl. nach Patent 387335. Durch die Erfindung wird die Bedienung der aus den beiden Druckstempeln bestehenden Vorrichtung durch Verwendung von Preßluft oder eines sonstigen Druckmittels vereinfacht. Zu diesem Zwecke ist die Vorrichtung so ausgebildet, daß einer der beiden Druckbügel den Fuß eines Preßluft- ο. dgl. Zylinders., der Stempel des anderen Bügels den Kolben des Preßluftzylinders bildet.The invention relates to an improvement of the bulging device and straightening of out-of-round weather ducts, thin-walled pipes and the like according to patent 387335. By the invention is the operation of the device consisting of the two pressure stamps through use simplified by compressed air or some other pressure medium. For this purpose, the device is designed so that one of the two pressure brackets the foot of a compressed air ο. Like. Cylinder., the stamp of the other bracket forms the piston of the compressed air cylinder.

In der Zeichnung ist ein Ausführungsbeispiel des Erfindungsgegenstandes dargestellt, und zwar zeigtThe drawing shows an embodiment of the subject matter of the invention, namely shows

Abb. ι die Vorrichtung in der Seitenansicht, währendFig. Ι the device in side view, while

Abb. 2 dieselbe im Längsschnitt erkennen ao läßt.Fig. 2 shows the same in longitudinal section ao.

Der Stempel des unteren Druckbügels f ist als Druckluftzylinder c ausgebildet, während in diesem der als Kolben α ausgebildete Stempel des oberen Druckbügels / geführt ist. »5 Der Kolben« ist mit einer in Längsrichtung' verlaufenden seitlichen Aussparung b versehen, die in Gemeinschaft mit dem Anschlagstift d im Druckzylinder c die geradlinige. Führung des Kolbens α und dessen Hubbegrenzung sichert. Mit g ist eine Dichtungsscheibe angedeutet, die vermittels der Schraube h an der unteren Stirnseite des Kolbens α befestigt ist. Das Abschlußorgan i ist mit dem Gewindestutzen k .am unteren Ende in den Zylindern eingeschraubt, während der Gewindestutzen m als Anschluß für die Schlauchleitung des Druckmittels dient. DieThe stamp of the lower pressure bracket f is designed as a compressed air cylinder c , while in this the stamp of the upper pressure bracket designed as a piston α / is guided. "5 The piston" is provided with a lateral recess b running in the longitudinal direction 'which, in common with the stop pin d in the pressure cylinder c, is the straight one. Guiding the piston α and its stroke limitation ensures. A sealing washer is indicated by g , which is attached to the lower end face of the piston α by means of the screw h. The closing element i is screwed into the cylinder with the threaded connector k. At the lower end, while the threaded connector m serves as a connection for the hose line of the pressure medium. the

Bedienung erfolgt vermittels der Handhabe «. Es steht natürlich nichts im Wege, das Abschlußorgan i auch weiter entfernt von der Vorrichtung anzuordnen, um dadurch die Bedienung der Vorrichtung in einer gewissen Entfernung von derselben vornehmen zu können.Operation takes place by means of the handle «. Of course, nothing stands in the way of arranging the closing element i further away from the device in order to be able to operate the device at a certain distance therefrom.
