Abstract: The invention is intended to improve 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 ignition of an explosive gas mixture, to the effect that the method is suitable and simplified for mass production. This object is solved by 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.

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: It shall be achieved by the invention that a workpiece for an explosion forming process, which can be inserted into a forming tool and which can be deformed from an initial shape by means of explosion forming, and the explosion forming method are improved such that a satisfactory quality of the workpiece with the desired wall thickness is achieved in a simple manner. This object is achieved by a workpiece and a respective explosion forming method in which the initial shape of the workpiece has at least in some portions a supply of material for the explosion forming process, which is pre-formed compared to adjoining portions or which is provided therewith.
