1. A method for explosive forming comprising:
- arranging at least one work piece in at least one die having a wall;
providing an induction element at least partially in the wall of the at least one die wherein said induction element has an ignition device formed from an ignition-free material, an electrical insulator, and wherein said electrical insulator electrically and thermally insulates said ignition device from said wall and a coil arrangement;
inductively heating the ignition device arranged in said wall with the coil arrangement; and
deforming the at least one workpiece with the induction element by igniting an explosive by means of induction during said step of inductively heating.

Abstract
With the invention, a method and device for explosive forming of work pieces, in which at least one work piece is arranged in at least one die and deformed by means of an explosive to be ignited, is to be improved, in that an ignition mechanism that is technically simple to handle, is produced with the shortest possible setup time, which permits the most precise possible ignition of the explosive with time-repeatable accuracy. This task is solved by a method and device, in which at least one work piece is arranged in at least one die and deformed by means of an explosive to be ignited, in which the explosive is ignited by means of induction.
