ι . Verfahren zum Bördeln eines Hohlgegenstandes, dadurch gekennzeichnet, dafs der vorstehende Rand des in ein Futter eingesetzten und mit diesem gedrehten Werkstückes mittelst sich neigender Rollen, welche am inneren Umfang des Werkstückes angeordnet sind, auf das Futter umgelegt wird.ι. Method for flanging a hollow object, characterized in that the protruding edge of the workpiece inserted into a chuck and rotated with it by means of inclined rollers, which are arranged on the inner circumference of the workpiece are placed on the feed.

2. Vorrichtung zur Ausführung des Verfahrens nach Anspruch 1., dadurch gekennzeichnet, dafs die Zapfen der Bördelrollen (I) einerseits mit einer fest angeordneten Scheibe (n), andererseits mit den Stangen (i) einer Traverse (h) gelenkig verbunden sind, welche bei ihrem durch eine Spindel (g) veranlafsten Vorgehen mittelst der Stangen (i) die Rollen und durch diese den Rand des sich2. Apparatus for carrying out the method according to claim 1, characterized in that the pins of the flanging rollers (I) are articulated on the one hand with a fixed disk (s), on the other hand with the rods (i) of a cross member (h) which in their action, initiated by a spindle (g), the rods (i) use the rollers and, through them, the edge of the itself

KAISERLICHESIMPERIAL PATENTAMT.PATENT OFFICE. Das neue Verfahren besteht darin, dafs Rollen durch ein Hebelwerk gegen den Rand des hohlen, rotirenden Metallkörpers geprefst werden, um bei ihrem zugleich bewirkten Neigen zur Seite um einen Winkel von ungefähr 45 ° den Rand des Hohlkörpers umzulegen.The new method consists in rolling against the edge by means of a lever mechanism of the hollow, rotating metal body are pressed in order to be effected at the same time Lean to the side to fold the edge of the hollow body at an angle of approximately 45 °. Wie Fig. ι zeigt, ist an der Drehbankbrille α das Futter &, in welches der zu bördelnde Körper c eingeführt ist, in gewöhnlicher Weise befestigt. Mit dieser Brille sind durch Stehbolzen d die Querhäupter e und f verbunden. Durch das Querhaupt f geht eine Schraubenspindel g, die beweglich in dem Querhaupt h gelagert ist, welches zwischen den Stehbolzen d geführt wird. Mit dem Querhaupt h sind zwei Stangen i verbunden, welche an dem einen Ende mittelst Gelenke k die Rollen I beliebiger Anzahl — hier von konischer Form —· tragen, die andererseits mittelst Gelenke m an der Scheibe η befestigt sind. Die Scheibe η ist mittelst des mit einem Bund ρ versehenen Bolzens 0 mit dem Querhaupt e verbunden, zwischen welchem und dem Bund ρ zur leichteren und schnelleren Ein- und Ausschaltung der Rollen zweckmäfsig eine Gabel q angebracht wird.As Fig. Ι shows, the chuck &, into which the body to be flanged c is inserted, is attached to the lathe goggles α in the usual way. The crossheads e and f are connected to these glasses by studs d. A screw spindle g passes through the crosshead f and is movably mounted in the crosshead h , which is guided between the stud bolts d. Two rods i are connected to the crosshead h , which at one end by means of joints k carry the rollers I of any number - here of conical shape - which, on the other hand, are fastened to the disk η by means of joints m. The disk η is connected to the crosshead e by means of the bolt 0 provided with a collar ρ , between which and the collar ρ a fork q is expediently attached for easier and faster switching on and off of the rollers. Die Wirkungsweise der Vorrichtung ist folgende. Der Hohlkörper c wird in dem Futter b befestigt, welches er so weit überragen mufs, als der Rand umgelegt werden soll. Ist dann der Hohlkörper in Drehung versetzt, so bewegt man die Spindel g vor, wobei mittelst der Stangen i durch die Rollen / der Rand r des Hohlkörpers allmälig umgelegt wird, so dafs er schliefslich die aus der Figur ersichtliche Form annimmt.The operation of the device is as follows. The hollow body c is fastened in the chuck b , which it must protrude as far as the edge is to be turned over. If the hollow body is then set in rotation, the spindle g is moved forward, with the rollers / edge r of the hollow body gradually turning over by means of the rod i , so that it finally assumes the shape shown in the figure. Fig. 2 bis 4 t zeigen einige Formen der Rollen Z; mit den Formen nach Fig! 3 und 4 kann man Rohre herstellen, deren Flantsch gleichzeitig Nu then erhält, in welche sich etwa einzulegendes Dichtungsmaterial hineinprefst.Figures 2 to 4t show some forms of the rollers Z; with the forms according to Fig! 3 and 4 you can produce tubes whose flange receives nut at the same time, into which about to be inserted sealing material is pressed. Die auf die neue Weise hergestellten Rohre werden genau centrisch gebördelt, und die umgelegte Fläche soll so eben werden, dafs zwei Rohre unmittelbar mit einander verbunden werden können und an der Verbindungsstelle vollständig dicht sind.The pipes produced in the new way are flanged exactly centrically, and the The area covered should be so level that two pipes are directly connected to one another and are completely tight at the junction.
