Definitions
- At least one punch 13 is provided in the embossing die 11 and coaxially therewith, which advantageously perforates the hollow profile 2 after the completed embossing process.
- An embossing direction of the embossing die 11 is parallel to the direction of movement of the punch 13.
- this punch 13 another work step that can also be carried out optionally, namely the punching of the hollow profile 2, is integrated into the tool 1, as a result of which the manufacturing process can also be rationalized.

Abstract
La présente invention concerne un outil (1) pour réaliser une déformation haute pression interne d'un profilé creux (2). Selon l'invention, l'outil (1) convient à la fois à la déformation du profilé creux (2) et à l'application d'une empreinte sur l'extérieur du profilé creux (2). L'outil (1) présente à cet effet une matrice d'impression (11) qui peut se déplacer transversalement à la longueur du profilé creux (2), et une matrice à trous (13) coaxiale avec la matrice d'impression (11).
