Method and forming device for producing ring-shaped formed parts

A method for producing an inner and an outer ring-shaped formed part from a blank, comprising the steps:

• cup extrusion of the blank to form a cup having a drawn-out cup base and an adjoining stepless cup wall, wherein during the cup extrusion of the blank the cup base is shaped between an end face of a first forming punch portion and a support face of an ejector, and wherein during the cup extrusion of the blank at least a part of a peripheral inner surface of the inner ring-shaped formed part is shaped by a peripheral outer surface of the first forming punch portion;
• forming of the cup wall in such a way that the formed cup wall comprises an inner ring-shaped section and an adjoining outer ring-shaped section which is partly offset in an axial direction;
• and
• separation of the outer ring-shaped section from the inner ring-shaped section and separation of the inner ring-shaped section from the drawn-out cup base, the detached outer ring-shaped section constituting the outer ring-shaped formed part and the detached inner ring-shaped section constituting the inner ring-shaped formed part.
