Abstract
A method and a device for shaping sheet metal to form a main structure is described, minor structures being created in the planar sheet metal before shaping to form the main structure, which is rotationally symmetrical, for example. This method and device are particularly advantageous because they make it possible to inexpensively and precisely design shell-shaped parts for torque converters, such as a pump shell, a turbine shell or the inner ring of a pump or the inner ring of a turbine.
