With the invention, it is intended to improve a method and a device for explosion forming of workpieces, wherein at least one workpiece (5) is arranged in at least one die (2) and is formed by means of an explosive agent (8) which is to be ignited, in such a way as to provide a technically easy-to-handle ignition mechanism with the shortest possible setting-up times, which ignition mechanism permits as precise an ignition of the explosive agent (8) as possible with repeatable accuracy. Said object is achieved by means of a method and a device in which at least one workpiece (5) is arranged in at least one die (2) and is formed by means of an explosive agent (8) which is to be ignited, in which the explosive agent (8) is ignited by means of induction.
L'invention concerne un procédé et un dispositif de formage par explosion de pièces, au moins une pièce (5) étant disposée dans au moins un moule (2) et y étant façonnée à l'aide d'un explosif (8) à amorcer. L'invention vise à améliorer ce procédé et ce dispositif de façon à obtenir un mécanisme d'amorçage d'un maniement techniquement simple avec un temps de préparation minimal, qui permette un amorçage de l'explosif (8) le plus précis possible avec une précision reproductible dans le temps. Elle y parvient par le fait que, pour un procédé et un dispositif selon lesquels au moins une pièce (5) est disposée dans au moins un moule (2) et y est façonnée à l'aide d'un explosif (8) à amorcer, l'explosif (8) est amorcé à l'aide d'une induction.
