Abstract

L'invention concerne un procédé de rigidification d'une coupelle inférieure (2) d'une butée de suspension de véhicule automobile, ladite coupelle présentant un zone d'appui (3) pour un ressort de suspension, ledit procédé prévoyant d'associer à ladite coupelle un insert rigide (4) présentant une couronne (4a) disposée en regard de ladite zone d'appui, ledit procédé prévoyant, préalablement à l'association de l'insert (4) à ladite coupelle, une conformation de ladite couronne dans une cavité formée entre un poinçon (5) et une matrice (6), ladite conformation étant réalisée sur une course d'écrasement de la couronne (4a) dans ladite cavité, ladite course étant agencée pour former des motifs géométriques (7) de rigidification dans ladite couronne au moyen d'empreintes (8a, 8b) réparties angulairement dans ladite cavité.The invention relates to a method of stiffening a lower cup (2) of a motor vehicle suspension stopper, said cup having a bearing zone (3) for a suspension spring, said method providing for associating with said cup a rigid insert (4) having a crown (4a) disposed facing said bearing zone, said method providing, prior to the association of the insert (4) with said cup, a conformation of said crown in a cavity formed between a punch (5) and a die (6), said conformation being carried out on a crushing stroke of the crown (4a) in said cavity, said stroke being arranged to form geometric patterns (7) for stiffening in said ring by means of impressions (8a, 8b) distributed angularly in said cavity.
