Abstract
Procédé et équipement pour fabriquer un bras coudé pour un vilebrequin soudé; en liaison avec l'extrusion de l'un ou l'autre tourillon 35, 36 une dépression 23, 27 possédant une section transversale légèrement incurvée est forgée à la presse dans la surface latérale adjacente de l'ébauche, concentriquement audit tourillon, ladite dépression s'étendant le long de la surface du tourillon suivant un angle d'au moins 60 degrés de chaque côté de la ligne reliant les centres des deux tourillons et se raccordant progressivement à la surface du tourillon; on obtient de ce fait une orientation du grain parallèle à la surface, qui améliore la résistance du vilebrequin fini
