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.

Device for explosive forming of a tube-like work piece, which includes a multipart forming die (1) almost fully enclosing the work piece in the closed state, with a forming area (7) that defines the final work piece shape, in which a plug (10) to form a seal between the forming die (1) and the plug (10) is provided in the area of at least one end of the forming die (1), and in which a nozzle arrangement (6), which has several forming die parts in the area of the access to the forming area (7) of forming die (1), is enclosed by a collar (11) in the closed state.
Explosion forming method for a tube-like work piece, in which the work piece is inserted into a multipart, opened die mold (1) and almost fully enclosed by it by closing the die mold (1), and in which a plug (10) to form a seal between the plug (10) and the die (1) is pressed on at least one opening of the work piece accessible from the outside, and in which a collar (11) in the closed die mold (1) is applied to a nozzle arrangement (6) enclosing several forming die parts, which forms the access to a forming area (7) of the forming die (1), in which the collar (11) encloses the nozzle arrangement (6).
