Abstract
Through the invention, a closure device for explosive forming with a connection unit movable relative to the explosive forming die between a working position on the die and a rest position is to be configured, so that the explosive forming die can be closed in simple and reliable fashion and, at the same time, the explosion forces supported. This task is solved by a closure device, in which a wedge structure is guided to move on a static holding structure and is motion-coupled to the connection unit, the resulting movement of the connection unit being directed across the movement of the wedge structure.
