Title
(EN) METHOD OF MAKING CONNECTING ROD
(FR) PROCEDE DE FABRICATION D'UNE BIELLE
Abstract
(EN)
A method of manufacturing a component formed of parts capable of being separated for reassembly around another component. The process starts by taking separate, e.g., rod (3, 3') and cap (5, 5') forgings and coining or forging them together prior to machining. The mating surfaces of the forgings are formed with a ridge-groove (9) or a dimple/lug-recess (12) configuration giving them a self-locating ability. After machining, the forgings are fractured along the original division to obtain two uniquely matched surfaces that need no further processing before being reassembled, e.g., to form a connecting rod for an internal combustion engine.
(FR)
L'invention a pour objet un procédé de fabrication d'un élément constitué de parties pouvant être séparées pour être ultérieurement ré-assemblées autour d'un autre élément. Ce procédé consiste à prendre des pièces forgées séparées, par exemple une bielle (3, 3') et un chapeau (5, 5') pour les forger ou les emboutir ensemble avant de les usiner. Les surfaces correspondantes des pièces forgées présentent une configuration de type arête-rainure (9) ou bosse/évidement-oeillet (12), ce qui leur permet de s'auto-positionner. Après l'usinage, les pièces forgées sont fracturées le long de leur division initiale pour donner deux pièces correspondantes uniques ne nécessitant pas d'autre traitement avant leur ré-assemblage, par exemple, pour former une bielle pour un moteur à combustion interne.
