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 molding 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 molding 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.
