摘要： A forge-molding method for forming a constant velocity joint outer ring comprising a shaft and a cup formed integral with and expanding radially and outwardly from one end of the shaft is provided. The method uses an ironing die apparatus which is provided with a lower molding die, an upper molding die and an ironing punch. The lower molding die is provided with a first cavity formed to have a final degree of product accuracy with respect to the shaft and adapted to apply a final ironing process to the shaft, while the upper molding die is provided with a second cavity for restraining the outer peripheral surface of the cup. Consequently, the accuracy of concentricity between the shaft and the cup can be securely maintained in a simple manner and a sufficient degree of accuracy of the inner peripheral surface and/or the inner diameter of the cup can be effectively secured.
