Verfahren zur Herstellung loser Flanschen an Metallrohren.Method of making loose flanges on metal pipes.
Den Gegenstand der Erfindung bildet ein Verfahren, Metallrohre, die aus einem festen Block hergestellt sind, mit losen Flanschen zu versehen.The object of the invention forms a method, metal pipes, which are made of a solid Block are made with loose flanges.
Zu diesem Zwecke werden die Rohre in bekannter Weise (durch Stauchen) mit festen Flanschen α (Fig. i) versehen, und zwar so, daß das Rohr c sich außerhalb des Flansches mit einem verdickten Ende b fortsetzt. InFor this purpose, the tubes are provided in a known manner (by upsetting) with fixed flanges α (Fig. I), in such a way that the tube c continues outside the flange with a thickened end b . In
ίο diesem Zustande werden die Flanschen zweckmäßigerweise fertig bearbeitet. Hierauf wird auf der Drehbank mittels geeigneter Drehstähle der in Fig. 2 mit d bezeichnete Teil des Metalles herausgestochen, und zwar so, daß der die Trennung bewirkende Ring sich nach dem Rohrende zu erweitert. Hierdurch wird der Flansch α von dem Rohre c losgelöst und stützt sich nach außen gegen die Rohrverdickung b (Fig. 3) ab.In this state, the flanges are expediently finished. Then the part of the metal designated by d in FIG. 2 is punched out on the lathe by means of suitable turning tools, in such a way that the ring causing the separation widens towards the end of the pipe. As a result, the flange α is detached from the tube c and is supported on the outside against the tube thickening b (FIG. 3).
Das Ausstechen kann auch so erfolgen, daß die aufeinanderliegenden Stützflächen e (Fig. 3) statt eines Kegels einen flachen Ring (Fig. 4) oder eine Kugelzone (Fig. 5) bilden.The cutting out can also take place in such a way that the support surfaces e (FIG. 3) lying on top of one another form a flat ring (FIG. 4) or a spherical zone (FIG. 5) instead of a cone.
