A METHOD AND SYSTEM FOR FORMING A CAM-ENGAGED ROCKER ARM

A method for forming a cam engaged rocker arm (10) includes a stamping process where metal is forced into die cavities to build up material in a desired area of a blank to create an intermediate article. The intermediate article is further formed by a shaving process where the built-up material and...

Zusammenfassung:	A method for forming a cam engaged rocker arm (10) includes a stamping process where metal is forced into die cavities to build up material in a desired area of a blank to create an intermediate article. The intermediate article is further formed by a shaving process where the built-up material and additional material is formed into a valve guide (40) for the rocker arm (10). L'invention concerne un procédé et un système permettant de former un culbuteur à contact de came (10). Le procédé selon l'invention comprend un processus d'estampage au cours duquel un métal est forcé vers des cavités de matrice pour accumuler de la matière dans une zone voulue d'une ébauche afin de créer un article intermédiaire. Cet article intermédiaire est soumis à un formage supplémentaire lors d'un processus de scalpage au cours duquel la matière accumulée et de la matière supplémentaire sont façonnées pour former un guide de soupape (40) pour le culbuteur (10).
