PATENTAMT.PATENT OFFICE.
Sollen zwei Blechschüsse für konische Rohre, Stutzen, Flammrohre, Dampfkesselmantel oder ähnliche Gegenstände vermittels hydraulischer Nietmaschine (Fig. 1) zusammengenietet werden, so zeigt sich, daß, wenn zwei Nieten gedrückt sind, der Blechrand α bezw. b von der Überlappung c bezw. d (Fig. 2) zwischen zwei Nieten durch den großen Druck sich abhebt, wodurch schon sehr viele Undichtigkeiten, hauptsächlich bei Kesselmänteln, trotz noch so vorsichtigen Stemmens, vorgekommen sind.If two sheet metal sections for conical pipes, nozzles, flame pipes, boiler jacket or similar objects by means of hydraulic riveting machine (Fig. 1) are riveted together, it is shown that when two rivets are pressed, the sheet metal edge α or. b from the overlap c respectively. d (Fig. 2) stands out between two rivets due to the great pressure, which has resulted in a lot of leaks, mainly in boiler shells, despite the careful prying.
Um nun dieses zu vermeiden, hat vorstehende Erfindung den Zweck, durch die Vorsprünge e und f bezw. g und h am Stempel (Fig. 2) die Blechränder α und b von der Überlappung c und d gleichzeitig beim Drücken des Nietes i mit anzudrücken.In order to avoid this, the above invention has the purpose, respectively , through the projections e and f. g and h on the punch (Fig. 2) to press the sheet metal edges α and b from the overlap c and d at the same time when pressing the rivet i .
Bei Doppelreihennietung muß der Stempel, wenn die Nieten der zweiten Nietreihe eingezogen werden, die Form nach Fig. 3 haben.In the case of double row riveting, the punch must be drawn in when the rivets of the second row of rivets are pulled in will have the shape of FIG.
