Abstract
PURPOSE: To manufacture the titled dies at low cost, by cutting the bottom of the ring type groove installed in the middle of the female die blank obtaining the female die and the mandrel plug, and by attaching this plug to the tip of the mandrel root of the male die.
CONSTITUTION: The male die 3 is formed from the male die blank so as to possess the mandrel root 4 lacking the bearing holder 10, and the ring type groove 7 is installed in the middle of the female die blank 5. Hereupon, the threaded hole 11 is tapped at the root 4; and the cavity 12 for forming the connecting chamber is formed in the blank 5, and a bolt hole 13 piercing the blank 5 is bored at the center of the cavity 12. The male die 3 and the blank 5 possessing the ring type groove 7 are heat treated in order to increase the hardness. The electric discharging cutter 14 is arranged on the side of cavity 12 so as to direct the electrode 15 against the bottom 17 of the groove 7; then, the bottom 17 is cut away by the electric discharge. Thus obtained mandrel plug 9 possessing the bearing holder 10 is attached to the tip of root 4 of the male die 3 with the bolt 19 forming the mandrel 6; this mandrel 6 is inserted into the open mouth 16 of the female die 8 in order to combine the male die 3 with the female die 8.
