PATENTAMT.PATENT OFFICE.
Nach der Erfindung sollen Metallrohre mit tiefen, in sich zurücklaufenden Rillen hergestellt werden, und zwar unter möglichst geringer Verschwächung des Metalls.According to the invention, metal pipes with deep, recessed grooves are to be produced with the least possible weakening of the metal.
Die dazu notwendige Maschineneinrichtung ist entsprechenden Änderungen unterworfen. Das Rohr A (Fig. i) wird auf die Formstücke B und C gebracht, welche z. B. auf einer Welle D mittels einer Nut achsial verschiebbar angebracht sind. Dieselben werden in einem bestimmten Abstand voneinander gehalten und mittels einer Antriebscheibe F gedreht, wodurch auch das Rohr A in drehende Bewegung kommt. Es wird nun (Fig. 3 und 4) mittels einer Rolle oder eines Druckstahles G eine tiefe Rille in das Rohr A gedrückt, während gleichzeitig die Formstücke B und C das Rohr achsial bis auf die fertige Rillenstärke zusammenpressen. Dieser Vorgang wiederholt sich fortlaufend, bis das gerillte Federrohr in der bestimmten Länge fertig ist.The machine equipment required for this is subject to corresponding changes. The pipe A (Fig. I) is placed on the fittings B and C , which z. B. are mounted axially displaceably on a shaft D by means of a groove. The same are kept at a certain distance from one another and rotated by means of a drive pulley F , whereby the pipe A also comes into rotating motion. It is now (Fig. 3 and 4) by means of a roller or a pressure steel G pressed a deep groove into the pipe A , while the fittings B and C compress the pipe axially to the finished groove thickness. This process is repeated continuously until the grooved spring tube is finished in the specified length.
Durch Anbringen von mehreren Formstücken, welche nach Herstellung der Rillen entfernt werden, kann eine große Anzahl Rillen gleichzeitig fertiggestellt werden. Es können ferner die Druckwerkzeuge während des Einrillens in um das Rohr kreisende Bewegungen versetzt werden, um eine schnellere Wirkung zu erzielen.By attaching several shaped pieces, which are removed after the grooves have been made a large number of grooves can be completed at one time. It can also sets the pressure tools in circular movements around the pipe during grooving to have a faster effect.
