Abstract

L'invention a trait à un procédé de laminage transversal de pièces décolletées à symétrie de rotation, de forme allongée. Elle a pour objet un procédé selon lequel, par réduction partielle du diamètre initial, la matière flue latéralement par réduction partielle de diamètre radialement en un bourrelet de volume dosé à un écartement défini axialement par l'élément à réaliser et ensuite est déplacée à l'endroit prévu par fluage axial de la matière nécessaire à la réalisation de la partie façonnée. Application : notamment à la réalisation de goujons, de blocs de commutation de transmission, de pivots sphériques.
