Abstract

L'invention concerne un procédé de fabrication de crampons métalliques antidérapants pour pneumatiques constitués d'un bâtonnet en matériau dur et d'un fourreau métallique présentant un axe de révolution, ce fourreau comportant un logement pour le bâtonnet, au moins une collerette d'ancrage et une partie rétrécie de diamètre plus faible que les parties inférieure et supérieure adjacentes. Ce procédé consiste : a. à réaliser une ébauche frittée de densité d'au moins 85 % de la densité théorique comportant le logement du bâtonnet, b. à introduire le bâtonnet dans son logement avec un espace vide entre le bâtonnet et le fond du logement inférieur à 0,6 mm, c. à amener ensuite le fourreau par décolletage, en particulier dans la partie rétrécie, à sa forme définitive, en maintenant serrée la partie du fourreau entourant le bâtonnet. Application aux crampons de faible diamètre.
