KAISERLICHESIMPERIAL
PATENTAMT.PATENT OFFICE.
Die Erfindung bezweckt, bei Nietungen die Sicherheit der Verbindung zu erhöhen. Es werden die Nietlöcher nicht einfach cylindrisch gestaltet, dieselben werden vielmehr in den zu verbindenden Platten mit Aussparungen versehen, in welche das Material des Nietschaftes beim Nieten hineingestaucht wird. Die Aussparungen können die Form von ringförmigen Wülsten haben, oder auch in schraubenförmigen Windungen sich über die ganze Länge des Nietloches bezw. Schaftes erstrecken.The aim of the invention is to increase the security of the connection when riveting. It If the rivet holes are not simply made cylindrical, they are rather closed in the connecting plates are provided with recesses in which the material of the rivet shank is compressed when riveting. The recesses can be in the form of annular ones Have ridges, or in helical turns extending over the entire length of the Rivet holes or Extend the shaft.
Auf der Zeichnung sind derartige Nietverbindungen beispielsweise dargestellt.
' Fig. ι zeigt eine Verbindung, bei welcher der Schaft α in beiden Platten je einen ringförmigen
Wulst b aufweist.In the drawing, such rivet connections are shown, for example.
'Fig. Ι shows a connection in which the shaft α has an annular bead b in each of the two plates.
Fig. 2 zeigt dagegen eine Verbindung, bei welcher der Schaft auf seiner ganzen Länge von einem schraubenförmig gewundenen Wulst b umgeben ist.In contrast, FIG. 2 shows a connection in which the shaft is surrounded over its entire length by a helically wound bead b .
Es wird durch diese Anordnung eine Entlastung der Nietköpfe bezw. eine Erhöhung der Sicherheit der Verbindung erzieh. Bei der Anordnung der ringförmigen Vertiefungen wird eine stufenweise, bei den schraubenförmigen Windungen eine allmählich fortschreitende Vertheilung der Last über die ganze Länge des Schaftes erreicht.It is a relief of the rivet heads BEZW by this arrangement. an increase the security of the connection educate. When arranging the annular recesses becomes a gradual one, with the helical turns a gradually progressing one The load is distributed over the entire length of the shaft.
Bei der bisher gebräuchlichen Nietung mit cylindrischem Schaft wird der Gleitungswiderstand zum gröfsten Theil auf die Nietköpfe übertragen. Beim Erkalten zieht sich der Nietschaft naturgemäfs zusammen und es wird beim Ueberschreiten einer gewissen Maximalbeanspruchung der Nietkopf abspringen, wodurch die Verbindung natürlich zerstört wird. Kommt bei der neuen Nietverbindung ein Abspringen des Kopfes vor, so wird die Verbindung trotzdem nicht zerstört, da die eingestauchten Wülste oder Schraubengewinde immer noch eine gewisse Auflagefläche und somit einen erheblichen Halt bieten.In the case of riveting with a cylindrical shaft, which has been used up to now, the sliding resistance is increased for the most part transferred to the rivet heads. The rivet pulls itself when it cools down naturally together and it becomes when a certain maximum load is exceeded the rivet head pops off, which of course destroys the connection. If the new rivet connection comes off of the head, the connection is still not destroyed because the swaged-in bulges or screw threads still have a certain contact surface and thus a considerable one Offer support.
Als vortheilhaft erweist ,sich auch die vergröfserte Oberfläche des Nietschaftes, indem sie wegen der gröfseren Abkühlungsfläche eine schnellere Erkaltung des Nietes zur Folge hat.The enlarged one also proves to be advantageous Surface of the rivet shank by creating a results in faster cooling of the rivet.
