Abstract (en)
[origin: EP2460599A1] The method involves sliding an un-toothed pot-shaped sheet metal part (1) on a mandrel formed with an external toothing corresponding to the internal toothing of the sheet metal part so that an outer profile is rolled on the pot-shaped sheet metal part. A completed shape of longitudinal grooves is carries out in the course of an individual press stroke. An independent claim is also included for an apparatus for manufacturing an internally-and externally-toothed pot-shaped sheet metal part.
