  • Patent number: 10646911
    Abstract: A method for producing a complex sheet metal part includes clamping a border region of the metal sheet between a die ring of an upper tool part of a pressing tool and a downholder of a lower tool part of the pressing tool; moving the upper tool part further downwards thereby pulling the metal sheet over extended punch inserts of a punch of the lower tool part, thereby generating local material reserves of the metal sheet; moving the upper tool part further downwards while actively retracting the punch inserts, thereby releasing the local material reserves; and forming the metal sheet between the die and the punch using only the local material reserves.
