摘要： The invention relates to a closure device (1) for explosion forming having a connection device (14) opposite the explosion forming tool (5, 6) which can be moved between a working position at the tool and a resting position (18). Said closure device is made in such a manner that the explosion forming tool (5, 6) can be closed in a simple and safe way and at the same time the explosion forces can be tolerated. The problem of making such a device is solved by a closure device (1), wherein a wedge structure (10) is movably guided on a static holding structure (9) and is movably coupled to the connection device (14). The resulting movement (28) of the connection device (14) is directed transversally to the movement (27) of the wedge structure (10).

摘要： With the invention, it is intended to improve a method and a device for explosion forming of workpieces (18), wherein at least one workpiece (2) is arranged in at least one die and is formed there by means of an explosive agent (7) 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 as possible with repeatable accuracy. Said object is achieved by means of a method and a device in which at least one workpiece is arranged in at least one die and is formed there by means of an explosive agent which is to be ignited, in which the explosive agent is ignited by means of at least one beam of energy (12).

摘要： According to the invention, a method and a device for explosion forming a tubular workpiece, which comprises a multi-piece shaping tool (1) which almost completely surrounds the workpiece when in the closed state and which is provided with a stopper (10) in the region of at least one end of the shaping tool (1), may be improved such that the tubular workpiece can be shaped in a simple and economical manner requiring fewer individual working steps. The above is achieved by a method and a device for explosion forming, wherein a sealing between the forming tool (1) and the stopper (10) is formed when the stopper (10) is used. The end of the workpiece is tensed and deformed between the stopper (10) and the shaping tool (1).

摘要： The invention is intended to improve a mould arrangement (1) and a method for the explosion forming of a workpiece (12) by means of gas explosion, in which the workpiece is arranged in a receiving space (15) of a forming mould (2), the receiving space being filled at least partially with liquid (26) and the explosion being triggered by igniting an explosive gas mixture (23), to the extent that the mould arrangement and the method are simplified and suitable for mass production. This object is achieved by a mould arrangement and a method for the explosion forming of a workpiece by means of gas explosion in which the workpiece is arranged in a receiving space of a forming mould (2), wherein the receiving space is at least partially filled with liquid and the explosion is triggered by igniting an explosive gas mixture in which the exposive gas mixture is at least partially provided over the surface of the liquid (22) before the ignition.

摘要： The invention aims to improve a device for supplying fluid for explosion forming, which device has a valve (2) and an actuating mechanism (3) for actuating the valve, to the effect that the device, with a technically simple construction, permits both good filling of a mould with the fluid and good sealing during the explosion forming process. This problem is solved by a device for supplying fluid for explosion forming, which device has a valve and an actuating mechanism for actuating the valve and in which the actuating mechanism is arranged separately from the valve in an actuated state of the valve.
