Abstract
This paper shows the benefits of a new draw die design. To achieve an optimized contact pressure between blankholder and blank a segment-elastic blankholder in combination with a prismatic designed draw ring can be used. In this case the blankholder pressure is very equal distributed and can be influenced locally by varying the cushion pin forces. For this a multipoint cushion system is required. Within a new press concept as shown in this paper, this multipoint cushion system can be realized by short stroke hydraulic cylinders.
