Title (EN) METHOD AND DEVICE FOR SHAPING A WORKPIECE HAVING A DRUM-TYPE PERIPHERAL WALL
(FR) PROCÉDÉ ET DISPOSITIF POUR FAÇONNER UNE PIÈCE COMPRENANT UNE PAROI PÉRIPHÉRIQUE EN FORME DE TAMBOUR
(DE) VERFAHREN UND VORRICHTUNG ZUM UMFORMEN EINES WERKSTÜCKS MIT TROMMELFÖRMIGER UMFANGSWAND
Abstract:
(EN) The invention relates to a method for shaping a workpiece (1) having a drum-type peripheral wall (2), on the inner face (3) of which an inner profile (5) featuring longitudinal ribs (6) is formed by feeding at least one profiling roll (12) to said inner face (3). According to the invention, at least one rotatably mounted profiling roll (12) is fed to an inner face (3) of the peripheral wall (2) of the workpiece (1), and said at least one profiling roll (12) rotates relative to the inner face (3) of the peripheral wall (2) such that the inner profile (5) is formed in the inner face (3) in a non-cutting manner.
(FR) L'invention concerne un procédé pour façonner une pièce (1) comprenant une paroi périphérique en forme de tambour (2), sur la face intérieure (3) de laquelle un profil intérieur (5) pourvu de nervures longitudinales (6) est façonné par le placement d'au moins un rouleau de profilage (12). Selon l'invention, au moins un rouleau de profilage (12) rotatif est placé sur une face intérieure (3) de la paroi périphérique (2) de la pièce (1) et le ou les rouleaux de profilage (12) tournent par rapport à la face intérieure (3) de la paroi périphérique (2), le profil intérieur (5) étant façonné sans copeaux.
(DE) Die Erfindung betrifft ein Verfahren zum Umformen eines Werkstückes (1) mit einer trommeiförmigen Umfangswand (2), an deren Innenseite (3) ein Innenprofil (5) mit Längsrippen (6) durch Zustellen mindestens einer Profilierungsrolle (12) eingeformt wird. Gemäß der Erfindung ist vorgesehen, dass mindestens eine drehbar gelagerte Profilierungsrolle (12) an eine Innenseite (3) der Umfangswand (2) des Werkstücks (1) zugestellt wird und die mindestens eine Profilierungsrolle (12) relativ zu der Innenseite (3) der Umfangswand (2) umläuft, wobei das Innenprofil (5) spanlos eingeformt wird.
