Abstract: With the invention, a method and a device for explosive forming of a tubular work piece, which comprises a multipart forming die almost fully enclosing the work piece in the closed state, and in which a plug is provided in the area of at least one end of the forming die, is to be improved, in that forming of a tubular work piece is possible in a simple method that promotes fewer individual work steps and is therefore cost-effective. This task is solved by a method and a device for explosive forming, in which a seal between the forming die and the plug is formed when the plug is inserted, in which the work piece end is mounted between the forming die and deformed.

Abstract: With the invention, a device for fluid feed for explosive forming, which has a valve and an activating mechanism to activate the valve, is to be improved, so that the device permits both good filling of a die with fluid and good sealing during the explosive forming process in a technically simple design. This task is solved by a device for fluid feed for explosive forming that has a valve and an activating mechanism to activate the valve, in which the activating mechanism is arranged separate from the valve in an inactivated valve state.

Abstract: The invention relates to a device for explosive forming of workpieces, comprising an ignition chamber and an ignition mechanism, wherein an explosive agent can be ignited at an ignition location in the ignition chamber using the ignition mechanism, and an ignition chamber outlet is provided, to be improved such that the ignition mechanism has a longer service life. The aim is achieved by a device wherein an impact breaker is provided in the propagation path (37) of the detonation wave.

Abstract: With the invention, a method and a device for explosive forming of work pieces, in which at least one work piece is arranged in at least one die and there deformed by means of an explosive to be ignited, is to be improved, in that an ignition mechanism that is technically easy to handle is produced with the shortest possible setup times, 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 there by means of an explosive being ignited, in which the explosive is ignited by means of at least one energy beam.

Abstract: The invention is intended to improve a tool arrangement and method for explosive forming of a workpiece by means of gas explosion, in which the workpiece is arranged in a intake area of a moulding tool, wherein the intake area is at least partially filled with liquid and the explosion is triggered by means of ignition of an explosive gas mixture, to the effect that the tool arrangement and the method are suitable and simplified for mass production. This object is solved by means of a tool arrangement and a method for explosive forming of a workpiece by means of gas explosion, in which the workpiece is arranged in a intake area of a moulding tool, wherein the intake area is at least partially filled with liquid and the explosion is triggered by means of ignition of an explosive gas mixture, in which the explosive gas mixture is provided at least partially above the surface of the liquid before the ignition.

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.

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.

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.
