Description
Die Erfindung betrifft ein Verfahren zum Befestigen von Anschlußstutzen an Blechbehältern. Es ist bereits bekannt, solche Stutzen mit einer verengten Bohrung zu versehen und diese nach Einstecken des Stutzens in ein Loch'des Behälters mit einem passenden konischen Dorn aufzutreiben, so daß der Stutzen durch Klemmung festsitzt. Dieses Verfahren hat den Nachteil, daß der Dorn schlagartig vorgetrieben ίο werden muß, also sehr dünnwandige Behälter verbeult werden würden. Zur Behebung dieses Nachteils wird der Dorn gemäß der Erfindung allmählich durch Einschrauben in den Stutzen vorgetrieben. Die Erfindung sei nachstehend näher beschrieben.The invention relates to a method for attaching connecting pieces to sheet metal containers. It is already known to provide such nozzles with a narrowed bore and this after Insertion of the nozzle into a hole in the container with a suitable conical mandrel to drive up so that the nozzle is tight by clamping. This procedure has the Disadvantage that the mandrel must be driven forward suddenly ίο, so very thin-walled container would be dented. To overcome this disadvantage, the mandrel according to the invention gradually advanced by screwing into the nozzle. The invention is as follows described in more detail.
Abb. ι zeigt einen Schnitt durch einen Anschlußstutzen mit äußerem Gewinde vor dem Eindrehen des Domes.Fig. Ι shows a section through a connection piece with external thread before screwing in the dome.
Abb. 2 zeigt einen Schnitt durch einen Anschlußstutzen mit äußerem Gewinde nach dem Eindrehen des Domes,Fig. 2 shows a section through a connection piece with external thread after screwing in the dome,
Abb. 3 ein Beispiel des Blechlochens,
Abb. 4 einen Schnitt durch einen Anschlußstutzen mit innerem Gewinde.
In das Blech 10 wird ein Loch 1 vom Durchmesser des Zapfens 2 gebohrt. Das Loch. 1
erhält zweckmäßig einige Nuten 3. In das Loch ι wird der Zapfen 2 gesteckt, so daß der
Flansch 4 auf dem Blech aufliegt. Nun steckt man in das Loch 5 des Stutzens 6 den mit
einer konischen Spitze versehenen Dorn 7. Der Dorn 7 ist an einer Mutter 8 (Abb. 1, 2) befestigt.
Dreht man die Mutter 8 nach unten, so druckt die konische Spitze des Domes 7 die verengte Bohrung 5 auseinander, so daß der
Zapfen 2 die Form gemäß Abb. 2 annimmt und das Blech festklemmt. Da auch die Nuten 3 vom
Zapfen 2 angefüllt werden, ist der Stutzen 6 auch gegen Drehung gesichert. Nach dieser
Operation wird die Mutter 8 mit dem Dorn 7 wieder entfernt.Fig. 3 an example of sheet metal punching,
Fig. 4 is a section through a connecting piece with an internal thread.
A hole 1 with the diameter of the pin 2 is drilled into the sheet metal 10. The hole. 1 expediently receives some grooves 3. The pin 2 is inserted into the hole ι so that the flange 4 rests on the sheet metal. The mandrel 7, which is provided with a conical tip, is now inserted into the hole 5 of the connecting piece 6. The mandrel 7 is fastened to a nut 8 (Fig. 1, 2). If the nut 8 is turned downwards, the conical tip of the dome 7 pushes the narrowed bore 5 apart, so that the pin 2 assumes the shape shown in FIG. 2 and clamps the sheet metal. Since the grooves 3 are also filled by the pin 2, the connecting piece 6 is also secured against rotation. After this operation, the nut 8 with the mandrel 7 is removed again.
Hat der Anschlußstutzen ein Innengewinde 9, so erhält der Dorn 7 ein Außengewinde, wie in Abb. 4 gezeigt.If the connecting piece has an internal thread 9, the mandrel 7 receives an external thread, such as shown in Fig. 4.
