- the invention relates to a device and a method having the features of the preamble of claim 1 and 28, respectively.
- a tubular workpiece is filled and sealed with a liquid, mostly water.
- a liquid mostly water.
- the workpiece is widened and gradually settles on the contours of the mold surrounding the workpiece.
- relatively high forces must be applied to deform the workpiece as well as to hold the mold together over a longer period of time. To get good results, the course of forces must be precisely controlled over time.
- the hydraulic forming can also be operated by means of explosive energy.
- This widely used method uses a liquid such as e.g. Water as a transfer medium for the explosion caused by the pressure waves.
- the workpiece usually a sheet metal blank, is placed on the cavity of a mold and sunk in a water bath. In the cavity below the workpiece, a vacuum is generally generated. By introducing an explosion charge into the water bath and then igniting the sheet metal blank is pressed into the mold and thus gets its final shape.
- This method finds e.g. in shipbuilding use. It is usually used for the production of flat, to be molded from a flat board items.
- this method although it does not require any liquid, is relatively complicated to handle and time consuming to handle.
- the mold must be pre-equipped with precast parts and then the camshaft shaft threaded through the openings of the individual cams.
- the side surfaces must be accurately fitted and mounted. Supply lines for the gas must be provided as well as a spark plug. These are all time-consuming individual steps.
- the end plates or side surfaces must either be re-sealed during each forming process or provided with a sealing element. The latter, however, is a wearing part, which causes additional costs. This complicated handling has a high time and thus cost. Therefore, this method could not prevail industrially.

- the collar By the collar, the individual mold parts are enclosed in the mouthpiece assembly and held together during the explosion process.
- At least a portion of the explosive forces acting on the mold can be redirected and press the plug against a die assembly which provides access to a molding area of the mold.
- the explosion forces which drive the device apart, deflected and used to push the plug against the mouthpiece assembly and thus seal the explosion chamber.
- At least a portion of the force acting on the mold explosion forces can be deflected and press a collar in a mouthpiece assembly of the molding tool embracing position.
- an ignition tube can be moved by means of a movement path between a working position in which the ignition tube presses on a mouthpiece arrangement of the molding tool, which forms the access to a molding area of the molding tool, and a rest position spaced apart from the molding tool.
