Latest Patents

Holger Dierolf holds a patent for a method and pressing tool designed for producing a complex formed sheet metal part with great drawing depth. This method involves clamping a border region of the metal sheet between a die ring of an upper tool part and a downholder of a lower tool part. The process includes moving the upper tool part downwards to pull the metal sheet over extended punch inserts, generating local material reserves. The upper tool part is then moved further down while actively retracting the punch inserts, releasing the local material reserves and forming the metal sheet using only these reserves.
