Abstract

L'invention concerne un ensemble matrice d'épaississement à base de filage de pelle pour un boîtier d'un amortisseur de vilebrequin à fluide de silicone. L'ensemble matrice comprend une matrice supérieure (1), une matrice inférieure (2), un premier outil à rouleau de filage de pelle (3) et un second outil à rouleau de filage de pelle (4) montés sur un métier à filer. Les matrices supérieure et inférieure sont montées sur un arbre rotatif de la machine à filer. Une ébauche circulaire (6) pour fabriquer un boîtier d'un amortisseur de vilebrequin à fluide de silicone est placée sur la matrice inférieure et pressée au moyen de la matrice supérieure. Les premier et second outils à rouleaux de filage de pelle sont montés sur des cadres d'outil à rouleaux du métier à filer et sont disposés symétriquement sur deux côtés des matrices supérieure et inférieure. Les axes des premier et second outils à rouleau de filage de pelle forment un angle inclus de 45 degrés avec une ligne centrale des matrices supérieure et inférieure. Par agencement symétrique des deux outils à rouleau de filage de pelle sur les deux côtés des matrices, la présente invention permet une application de force uniforme sur deux côtés pendant le fonctionnement de filage de pelle, ce qui permet d'améliorer la stabilité, d'empêcher une instabilité de pièce métallique provoquée par une charge irrégulière et d'améliorer la qualité de la pièce à travailler.
