Abstract

The circular shape of the ring is adhered to in every stage of assembly. The ring(s) is/are in one piece and not slit. The rings are formed by upsetting until no permanent deformation occurs. The external diameter of the rings is reduced by means of physical force without the influence of temperature and without losing the circular shape.

Description

Die vorliegende Erfindung befaßt sich mit der physikalischen Möglichkeit der automati­ sierten Innenmontage von Dichtringen und anderen Ringen aus nichtelastischen Werk­ stoffen sowie den Geraten und Apparaten für deren Durchführung.The present invention deals with the physical possibility of automati internally assembled sealing rings and other rings from non-elastic works materials and the devices and apparatus for their implementation.

Bei den bisher bekannten Montagetechniken besteht die Problematik, daß der nichtelasti­ sche Dichtring oder Ring aus seiner geometrischen Kreisform so in eine eingedrückte Linie verformt wird, um in die Innennut eingefügt zu werden, daß der verformte Bereich überdehnt wird und somit sehr anfällig gegen Bruch und Beschädigungen ist.In the previously known assembly techniques, there is the problem that the non-elastic gasket ring or ring from its geometric circular shape into a pressed one Line is deformed to be inserted into the inner groove that the deformed area is overstretched and is therefore very susceptible to breakage and damage.

Bei vorliegender Erfindung wird im gesamten Montageablauf die Kreisform des Dichtrin­ ges beibehalten. Der geschlossene Kreisring wird durch ein geeignetes Werkzeug insge­ samt soweit elastisch gestaucht, bis der Außendurchmesser kleiner ist als der Innen­ durchmesser der Bohrung, durch die er geführt werden muß. Bei dieser Stauchung wird die Kreisförmigkeit des Ringes nie unterbrochen. Ein geeigneter Montagedorn nimmt den gestauchten Ring von innen her auf und klemmt ihn axial ein. Durch diese Klemmung wird die verkleinerte Geometrie infolge Stauchung beibehalten. Der Montagedorn wird nun in bekannter Technik in den entsprechenden Hohlkörper eingeführt und positioniert. In der richtigen Position wird die Klemmung gelöst und der eingeführte Ring expandiert infolge seiner Werkstoffeigenschaften in die Ursprungsgröße. Er ist somit in der Innennut gratfrei und ohne Beschädigung eingeführt. Die Klemmechanismen werden nun soweit wegge­ schwenkt, daß der Montagedorn zurückgezogen werden kann.In the present invention, the circular shape of the seal is in the entire assembly process maintained. The closed circular ring is made using a suitable tool velvet up to the point where the outside diameter is smaller than the inside diameter of the hole through which it must be passed. With this upsetting the circularity of the ring never interrupted. A suitable assembly mandrel takes the compressed ring from the inside and clamps it axially. This clamping will maintain the reduced geometry due to compression. The assembly mandrel is now in known technology introduced and positioned in the corresponding hollow body. In the correct position, the clamp is released and the inserted ring expands as a result its material properties in the original size. It is therefore free of burrs in the inner groove and introduced without damage. The clamping mechanisms are now gone as far swivels that the assembly mandrel can be withdrawn.

Die vorliegende Anmeldung bezieht sich auf die Montage einzelner Ring und auf die ge­ meinsame Montage mehrerer Ringe gleichzeitig, nach dem gleichen Prinzip.The present application relates to the assembly of individual rings and to the ge joint assembly of several rings at the same time, according to the same principle.

Entsprechende Zuführ-, Vereinzelungs- und Transporteinheiten entsprechen dem Stand der Technik und sind deshalb nicht Gegenstand dieser Anmeldung.Corresponding feed, separation and transport units correspond to the status the technology and are therefore not the subject of this application.
