Abstract

Die Erfindung betrifft ein Verfahren und eine Vorrichtung zum Drückwalzen, insbesondere zum Einformen einer Innenverzahnung. Eine etwa zylindrische, dünnwandige Vorform wird auf einem Drückfutter eingespannt und mittels mindestens einem Wälzkörper an das Drückfutter angedrückt, wobei die Vorform relativ zu dem Wälzkörper rotiert. Dabei ist vorgesehen, daß die Vorform durch eine Vielzahl von Wälzkörpern umgeformt wird, welche ringartig um die Vorform angeordnet und in einem Käfig jeweils drehbar gelagert sind.

Figure 00000001
The invention relates to a method and a device for pressure rolling, in particular for molding an internal toothing. An approximately cylindrical, thin-walled preform is clamped onto a spinning chuck and pressed onto the spinning chuck by means of at least one roller body, the preform rotating relative to the roller body. It is provided that the preform is formed by a plurality of rolling elements which are arranged in a ring around the preform and are each rotatably mounted in a cage.
