Abstract
A method for producing a pot-shaped component from a flat blank. The method comprises the following steps: a) shaping the flat blank in at least one deep-drawing step to form a pot-shaped raw component having a substantially flat bottom area and a circumferential frame, and b) shaping the pot-shaped raw component in a tool having a conically tapered die that applies shear to the circumferential surface of the frame in the axial direction against the conically tapered die. In step b), the bottom area is clamped between an ejector and a hold-down mechanism and the conically tapered die surrounds the bottom area of the raw component radially on the outside and extends in a diameter-reducing manner in a tool stroke.
