  • Patent number: 9186716
    Abstract: A method of producing pressed metal sheet parts in an integrated process to prepare blanks of non-uniform thickness includes the steps of heating a steel sheet blank in heating equipment to the austenite region of the steel of the sheet steel blank in question, then forming the blank into a flat semi-finished product of non-uniform thickness in forming equipment, then immediately thereafter, without any further hearting of the semi-finished product, deep drawing the semi-finished product in deep drawing equipment into a final spatially shaped part. The method may further include cooling down the final spatially shaped part either during the drawing step or immediately after the deep drawing step in a manner which causes the final spatially shaped part to develop hardening microstructure, which imparts high strength to the final shaped part with non-uniform wall thickness.
