摘要： An improved lower die assembly is provided which allows a given lower die in a pressing machine to be replaced with another easily and in a short period of time relative to a die holder. In the lower die assembly in which a lower die is received and securely held in a die holder, the improvement comprises: a clamp means whereby the lower die when unclamped is received in the die holder so that the lower die can be extracted from the die holder upwards and then when clamped is securely held therein; and a lift means disposed below the lower die and whereby the lower die when unclamped is raised above an upper end of the die holder.

摘要： A method of manufacturing a driver plate comprises the steps of swaging the outer peripheral portion of a disk-shaped raw material in the radial direction thereof using a swaging die so as to form the outer peripheral portion in a thick wall portion, holding the swaged material between an upper and a lower die and pressing the material through the upper and lower dies so as to form it into a dish-shaped blank, and pressing radially the thick-walled outer peripheral portion of the dish-shaped blank held between a support die disposed either on the outside or on the inside thereof and a gear tooth profile forming die so as to form gear teeth either on the radially outside or on the radially inside of the outer peripheral portion. As an alternative, gear teeth may be formed by cold rolling work or gear teeth cutting work using a gear hobbing machine or one of other gear teeth cutting machines.
