Abstract
A method for producing an inner and an outer ring-shaped formed part from a blank includes the step of cup extrusion of the blank to form a cup having a drawn-out cup base and an adjoining stepless cup wall and the step of forming the cup wall in such a way that the formed cup wall includes an inner ring-shaped section and an adjoining outer ring-shaped section which is partly offset in an axial direction. The method further includes the step of separating the outer ring-shaped section from the inner ring-shaped section and separating 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.
