Description

Die Erfindung betrifft ein Verfahren zum Befestigen eines Arbeits­ kolbens auf der Kolbenstange eines Arbeitszylinders. Es ist bekannt, nach dem Positionieren eines Arbeitskolbens oder ähnlichen Teils auf einer Kolbenstange, letztere mittels Widerstandserhitzens beid­ seitig des Kolbens stark zu erwärmen. Anschließend wird eine Druck­ kraft auf die beiden Kolbenstangenenden ausgeübt, wodurch an den Stirnflächen des Arbeitskolbens Schweißwulste entstehen, welche ihn auf der Kolbenstange verankern (Zeitschrift "The Iron Age", 18. Januar 1962, S. 80).The invention relates to a method for fastening a work piston on the piston rod of a working cylinder. It is known, after positioning a working piston or similar part a piston rod, the latter by means of resistance heating both to heat up the side of the piston. Then there is a print exerted force on the two ends of the piston rod, whereby at the End faces of the working piston form welding beads, which create it anchor on the piston rod (magazine "The Iron Age", January 18, 1962, p. 80).

Dieses Verfahren ist umständlich und teuer, da eine Einrichtung zum Widerstandsschweißen erforderlich ist.This process is cumbersome and expensive, since a device for Resistance welding is required.

Es ist die Aufgabe der Erfindung, ein Verfahren zum Befestigen eines Arbeitskolbens auf der Kolbenstange eines Arbeitszylinders der eingangs erwähnten Art zu schaffen, das dadurch besonders einfach und billig ist, daß die Wulste durch Kaltverformen hergestellt werden.
It is the object of the invention to provide a method for fastening a working piston on the piston rod of a working cylinder of the type mentioned at the outset, which is particularly simple and inexpensive in that the beads are produced by cold working.

Ein Ausführungsbeispiel der Erfindung ist in der Zeichnung dargestellt und in der nachfolgenden Beschreibung näher er­ läutert.An embodiment of the invention is in the drawing shown and in the description below he purifies.

Die einzige Figur zeigt einen Abschnitt einer Kol­ benstange mit darauf befestigtem Arbeitskolben.The only figure shows a section of a col rod with working piston attached to it.

Mit 1 ist eine Kolbenstange bezeichnet, die vor dem Befe­ stigen des Arbeitskolbens 2 überall denselben Durchmesser aufweist. Der mit einer mittigen Bohrung versehene Arbeits­ kolben 2 wird auf die Kolbenstange 1 aufgeschoben und durch radiale Zuführung von Drückrollen 3 zu beiden Seiten des Arbeitskolbens endgültig positioniert. Dieses Positionieren erfolgt anfänglich durch den parallelen Abstand der Drück­ rollen, abgestimmt auf die Kolbenlänge zu beiden Seiten des Arbeitskolbens. Durch weiteres radiales Zustellen der Drück­ rollen werden dann Wulste 5 aufgeworfen und an den Arbeits­ kolben angedrückt, der nun absolut fest und dicht auf der Kol­ benstange fixiert ist. Bei diesem Vorgang wird die Kolben­ stange in eine rotierende Bewegung versetzt. Es wäre aber selbstverständlich auch möglich, die Kolbenstange festzu­ halten und die Drückrollen mit einer Vorrichtung um die Kol­ benstange herum laufen zu lassen. 1 with a piston rod is referred to, which has the same diameter everywhere before BEFE the working piston 2 . The working piston provided with a central bore 2 is pushed onto the piston rod 1 and finally positioned by radial feeding of pressure rollers 3 on both sides of the working piston. This positioning is initially carried out by the parallel distance between the pressure rollers, matched to the piston length on both sides of the working piston. By further radial delivery of the pressure roll beads 5 are then raised and pressed against the working piston, which is now absolutely firmly and tightly fixed on the rod ben Kol. In this process, the piston rod is rotated. But it would of course also be possible to hold the piston rod firmly and to let the pressure rollers run around the rod with a device.
