Abstract: A screwhead forming apparatus includes an operating mechanism driven to reciprocate, a male die driven by the operating mechanism to reciprocate and having a die cavity of a predetermined shape, a stationary female die, and a punch rod driven by the operating mechanism to impel the blank into the die cavity of the male die so as to forge an elongated blank. A compression spring assembly consists of a plurality of spring units which are disposed between the operating mechanism and the male die and which have different spring forces so that the spring assembly creates a successively increasing spring force to bias the male die to press against the female die after the male die is brought to contact the female die by the operating mechanism during movement of the punch rod relative to the female die. The spring units are compressed completely just before the blank is moved entirely into the die cavity of the male die so as to prevent removal of the male die from the female die.
