Abstract

Un dispositif d'étirage à froid (1) comprend une matrice d'étage avant (10) et une matrice d'étage arrière (11) disposée à l'arrière de la matrice d'étage avant (10) et comportant un degré de traitement de diamètre extérieur de 0,14 à 1,0 % qui est défini par l'expression (1). L'extrémité avant d'un tube à blanc (50), comme pièce à usiner, est pressée et insérée dans la matrice d'étage avant (10) et la matrice d'étage arrière (11). Après l'insertion, un bouchon (20) est inséré dans le tube à blanc (50) à partir de son extrémité arrière. Après insertion du bouchon (20), le tube à blanc (50) est tiré. La contrainte de traction résiduelle dans la surface périphérique extérieure du tube métallique fabriqué est réduite par ce procédé.
