Abstract

Une ébauche cylindrique, découpée dans un barreau d'acier, est soumise à une série d'extrusions à froid dans une presse de formage à froid à six filières et sept postes. Après qu'un voile s'étendant en travers de la cavité de l'ébauche a été éliminé par perçage, un anneau (76) est réalisé par extrusion, à l'aide d'un poinçon étagé, sur le pourtour de la face intérieure de la cavité de l'ébauche, afin d'etre utilisé comme siège d'un isolateur (84) de bougie d'allumage. Domaine d'application : fabrication de bougies d'allumage.A cylindrical blank, cut from a steel bar, is subjected to a series of cold extrusions in a cold forming press with six dies and seven stations. After a veil extending across the cavity of the blank has been removed by drilling, a ring (76) is produced by extrusion, using a stepped punch, around the periphery of the inner face. of the blank cavity, to be used as the seat of a spark plug insulator (84). Field of application: manufacture of spark plugs.
