Abstract

L'invention concerne un procédé et un système de formation d'un ensemble de culbuteur comprenant le formage à froid d'une pièce brute métallique de manière à produire une partie d'un ensemble de culbuteur. Cette partie présente une portion tubulaire qui rentre en contact rotatif avec une tige et un bras qui se couple à une tige de culbuteur. La portion est soudée au levier de soupape pour former l'ensemble de culbuteur.
