Abstract

Se proporciona un método de fabricación para una válvula de motor hueco, mediante la cual la condición de la superficie de una superficie interna que comprende un hueco se afina y el volumen del hueco se incrementa. El método de fabricación incluye un paso de forja para obtener una parte intermedia mediante un proceso de forja, en donde la parte intermedia tiene una parte cilíndrica y una parte con forma similar a la de un paraguas asociada con un extremo axial de la porción cilíndrica; un paso de tratamiento térmico para mantener la parte intermedia a una temperatura de calentamiento determinada durante un tiempo de conservación de temperatura determinado de acuerdo con el grosor de la pared de una parte cilíndrica, para suavizar la parte intermedia; un paso giratorio para extraer la parte cilíndrica de la parte intermedia que ha sido tratada con calor en una dirección axial mediante un proceso giratorio; y un paso de encuellamiento para reducir el diámetro de la parte cilíndrica extraída en la dirección axial, mediante un proceso de extracción para formar un vástago y una parte en forma de paraguas.A manufacturing method is provided for a hollow motor valve, whereby the surface condition of an internal surface comprising a hollow is refined and the volume of the hollow is increased. The manufacturing method includes a forging step to obtain an intermediate part by a forging process, wherein the intermediate part has a cylindrical part and an umbrella-like part associated with an axial end of the cylindrical portion; a heat treatment step to maintain the intermediate part at a determined heating temperature for a temperature retention time determined according to the wall thickness of a cylindrical part, to soften the intermediate part; a rotary passage for extracting the cylindrical part of the intermediate part that has been heat treated in an axial direction by a rotary process; and an interlocking step for reducing the diameter of the extracted cylindrical part in the axial direction, by means of an extraction process to form a stem and an umbrella-shaped part.
