Title (EN) MACHINING PROCESS FOR AUTOMOBILE OUTPUT SHAFT CASTING
(FR) PROCÉDÉ D'USINAGE POUR COULÉE D'UN ARBRE DE SORTIE D'AUTOMOBILE
(ZH) 一种汽车输出轴铸件的加工工艺
Abstract:
(EN) A machining process for an automobile output shaft casting, comprising the following steps: (1) manufacturing a mold; (2) molding by means of molding sand; (3) smelting steel into liquid steel; (4) pouring; and (5) cooling. The machining process performs pouring by using refined liquid steel, reducing the shrinkage cavities on the surface of the casting, improving the accuracy of the casting, and improving, after pouring, the strength of the casting by means of heat treatment; the invention is suitable for casting the automobile output shafts.
(FR) La présente invention concerne un procédé d'usinage pour une coulée d'arbre de sortie d'automobile, comprenant les étapes suivantes : (1) fabrication d'un moule; (2) moulage au moyen de sable de moulage; (3) fusion d'acier en acier liquide; (4) coulée; et (5) refroidissement. Le procédé d'usinage effectue la coulée en utilisant de l'acier liquide raffiné, de façon à réduire les cavités de retrait sur la surface de la pièce coulée, améliorer la précision de la coulée, et améliorer, après la coulée, la résistance de la pièce coulée au moyen d'un traitement thermique; l'invention est adaptée pour couler les arbres de sortie d'automobile.
(ZH) 一种汽车输出轴铸件的加工工艺,包括以下几个步骤:(1)制作模具;(2)型砂造型;(3)熔炼钢水;(4)浇注;(5)冷却。所述加工工艺通过采用精炼后的钢水进行浇注,减少了铸件表面的缩孔,提高了铸件的精度,浇注完成后通过热处理提高了铸件的强度,适合用于铸造汽车输出轴。
