Title (EN) MANUFACTURING OF COMPONENTS FOR VALVE MECHANISMS FOR INTERNAL COMBUSTION ENGINES
(FR) FABRICATION DE PIECES DESTINEES AUX MECANISMES DE SOUPAPES DES MOTEURS A COMBUSTION INTERNE
Abstract: front page image
(EN)A method for fabricating components such as rocker arms (4), cam followers (3) or cams for valve mechanisms for combustion engines, in which a billet of an MMC material (Metal Matrix Composite) containing 10-70 % ceramic material by volume in the form of particles or fibers is extruded into a bar (1, 2) having the cross-sectional profile of the final component (3, 4), and where separate billets for the respective components (3, 4) are obtained by cross-cutting the bar (1, 2) by means of cutting via high-speed machining, HSM.
(FR)L'invention concerne un procédé de fabrication de pièces telles que les culbuteurs (4), les galets suiveurs (3) ou les cames pour mécanismes de soupapes des moteurs à combustion. Ledit procédé consiste à extruder une billette d'un matériau composite à matrice métallique (CMM) renfermant de 10 à 70 % en volume d'un matériau céramique se présentant sous la forme de particules ou de fibres en une barre (1, 2) ayant le profil en coupe de la pièce finale (3, 4), les différentes billettes destinées à la fabrication des divers composants (3, 4) étant obtenues par le tronçonnage de ladite barre (1, 2) selon un usinage de coupe à grande vitesse.
