Abstract
Through the invention, an ignition device for explosive forming of work pieces in a forming die, which has an ignition mechanism and an ignition tube, and in which the ignition tube guides the explosion ignited by the ignition mechanism into the work piece inserted in the forming die, is to be improved, in that it permits, in practice, an arrangement of the ignition mechanism and forming die that is easier to handle and geared toward the occurring explosion forces. This task is solved by an ignition device, in which a curved guide is provided between the ignition mechanism and the forming die.
