Abstract: front page image
(EN)A casting and forging process of aluminum wheel which include spokes comprise: producing a wheel spoke member by low pressure cast, heating the member to the temperature of plastic deformation, then putting the member into a forging die for high pressure cast. The process further comprise: detecting the wheel spoke member for defect, machining the member to the desired dimension by machine work, then assembling the spoke member and a responding wheel rim for a completed wheel. The invention reduces the production steps, shortens the producing time, increases the availability of mental material, cuts off 40 % cost of the final product. The further advantage is that the completed wheel has 10 % elongation and more than 250N/mm tensile strength in the central hole section.
(FR)La présente invention concerne un processus de coulée et de forgeage de roue en aluminium qui comprend des rayons. Ce processus consiste à produire un rayon de roue par coulée en basse pression, à chauffer ce rayon à la température de déformation du plastique, puis à mettre ce rayon dans un moule de forgeage en vue d'une coulée de haute pression. Ce processus consiste aussi à détecter un défaut de rayon de roue, à usiner ce rayon à la dimension souhaitée à la machine, puis à assembler ce rayon et une jante de roue correspondante en vue de former une roue complète. Cette invention réduit les étapes de production, raccourcit le temps de production, augmente la disponibilité du matériau métallique et réduit les coûts du produit final de 40 %. Un autre avantage réside dans le fait que la route terminée possède une élongation de 10 % et une résistance en tension >250N/mm dans la partie du trou central.
