KAISERLICHESIMPERIAL
PATENTAMT.PATENT OFFICE.
Das Verfahren besteht darin, dafs bei Herstellung von Nietarbeiten Setz- und Schliefskopf gleichzeitig an das zum Nieten umzugestaltende Eisenstabstück angeprefst werden, wodurch an Kosten und Arbeit gespart wird und das nur einmal zu erhitzende Nietenmaterial weniger an Qualität einbüfst, als wenn es zur getrennten Bildung von Setz- und Schliefskopf zweimal erhitzt werden .mufs.The method consists in the fact that the riveting head is made by setting and closing heads at the same time be pressed against the piece of iron rod to be reshaped for riveting, whereby in costs and labor is saved and the rivet material only needs to be heated once loses less quality than when it comes to the separate formation of the set head and the bed head be heated twice .mufs.
Das Verfahren wird unter Anwendung eines einfachen und billigen Hülfswerkzeuges, welches bei jeder Nietmaschine anzuwenden ist, in folgender Weise ausgeführt:The method is carried out using a simple and inexpensive auxiliary tool, which to be used with every riveting machine, carried out in the following way:
Es wird das Rundeisen kalt oder warm in' Längen geschnitten, welche den zu bildenden Nieten entsprechen, und nun das eine Ende des genügend erhitzten Nieteisenstückes mit dem neuen Werkzeug, welches »Aufsetzer« genannt werden mag, gefafst, in das Nietloch gesteckt und geprefst. Der Nietstempel b setzt sich auf den Aufsetzer c auf und prefst denselben an den zu nietenden Gegenstand, während α den einen Kopf d bildet und gleichzeitig das Material für den Kopf dl in den Aufsetzer prefst. Letzterer wird nun entfernt nnd der Kopf d1 auf gewöhnliche Weise fertig gebildet.The round bar is cut cold or warm into lengths that correspond to the rivets to be formed, and one end of the sufficiently heated piece of rivet iron is then gripped, inserted into the rivet hole and pressed with the new tool, which may be called a "setter". The riveting punch b sits down on the topper c and prefst it to the object to be riveted, while α forms one head d and at the same time prefst the material for the head d l in the topper. The latter is now removed and the head d 1 is finished in the usual way.
In der Fig. 1 der beiliegenden Zeichnung ist die einfachste Form des Aufsetzers in Verwendung stehend im Aufrifs dargestellt. Fig. 2 zeigt eine Unteransicht des Hülfswerkzeuges. Dasselbe wird vortheilhaft aus Stahl .geschmiedet und mit einer Handhabe zum Halten versehen. In der Mitte hat der Aufsetzer eine konische Bohrung, deren Cubikinhalt gleich ist jenem des zu bildenden Kopfes. Die Konicität ist nothwendig, um den Aufsetzer rasch entfernen zu können. Die obere Fläche kann, wie punktirt angedeutet, in der Form des Nietkopfes ausgebildet sein, um dem Nietstempel eine passende Druckfläche darzubieten.In Fig. 1 of the accompanying drawings, the simplest form of the Aufsetzers is in use shown standing upright. Fig. 2 shows a bottom view of the auxiliary tool. It is advantageously forged from steel and provided with a handle to hold it. In the middle of the topper has a conical hole, the cubic content of which is the same as that of the head to be formed. The taper is necessary in order to remove the impact quickly to be able to. The upper surface, as indicated by dots, can be in the shape of the rivet head be designed to present the riveting die with a suitable pressure surface.
Selbstverständlich ist das beschriebene Verfahren auch bei versenkten Nieten, wie solche in Fig. ι angedeutet sind, mit entsprechend geformten Aufsetzern anzuwenden. In diesem Falle wird die obere Fläche des Werkzeuges glatt gelassen, wodurch man den VortheiJ hat, dafs bei Nietung eines Gegenstandes, in welchem Niete mit Voll- und versenkten Köpfen vorkommen, der Nietstempel nicht gewechselt werden mufs, da man zur Herstellung der versenkten Nietköpfe bei der zweiten Pressung den Aufsetzer nur umzuwenden braucht, so dafs eine glatte Oberfläche als Stempel wirkt.It goes without saying that the method described is also applicable to countersunk rivets such as these are indicated in Fig. ι to be used with appropriately shaped attachments. In this Trap, the upper surface of the tool is left smooth, which has the advantage of that when riveting an object in which rivets with full and recessed heads it can happen that the riveting die does not have to be changed, as one is required to produce the countersunk ones The rivet head only needs to be turned over during the second pressing, so that a smooth surface acts as a stamp.
