Abstract

La présente invention a trait à un outil (10) réalisé en métal fritté, tel qu'un acier rapide T15 modifié sous forme de poudre, et présentant un profil d'extrémité à lobes multiples (12) pour le poinçonnage d'évidements à lobes multiples dans des pièces, tels que dans les têtes d'éléments de fixation. L'outil (10) est homogène et contient uniquement des carbures qui sont de taille relativement petite, comprise entre 1 et 4 microns. L'invention a également trait à un procédé pour la fabrication d'un tel outil. Le procédé comprend la coupe d'une barre de métal fritté et le façonnage de la pièce coupée pour fournir un outil à lobes multiples. La pièce finale présente une densité théorique de 100 %, par opposition à la densité des pièces métalliques moulées par injection de 95 à 98 % de densité. Lors de l'utilisation de l'outil, la partie d'extrémité, grâce à son procédé de fabrication, présente une force de colonne accrue et une résistance au choc améliorée.
