Abstract

L'invention concerne un procédé de fabrication d'une pièce de boulonnerie, tel qu'une vis (10) ou un écrou, comportant une tête (12) comportant un pourtour (18) comprenant au moins un épaulement (20) s'étendant dans un plan radial. Le procédé comporte au moins les étapes de mise en forme suivantes: Cisaillage d'un fil de matière (38) de manière à obtenir une pièce de longueur déterminée, calibrage de la pièce de manière à corriger la géométrie de la pièce, ébauchage de la pièce calibrée (34), de manière à obtenir la tête de la pièce de boulonnerie, et finition de la pièce ébauchée au moyen d'un troisième poinçon (36) de manière à former une tête comportant au moins un épaulement (20), les étapes de calibrage, d'ébauchage et de finition étant réalisées uniquement par frappage à froid.
