Abstract

PURPOSE: To contrive the reduce the man-hour, the material cost, etc., by applying the wire-out electrode-discharge forming work to the blank in order to simultaneously manufacture the punch and the die.
CONSTITUTION: The blank 3 is worked to provide the screw hole 4a, the knock-pin hole 5a, and the wire insertion hole 2c, and is treated for hardening. Next, the plate 1 is set to the blank 3 using the screw 4 and the knock-pin 5. Then, the reference planes 6, 7, of the plate 2 are aligned to the reference planes of the plate 1, and the plate 2 is set to the blank 3 similarly to the plate 1 so as to sandwich the blank 3. Next, the plates 1, 2, are removed from the blank 3, and the wire or the blank is inclined by a suitable angle 9a against the moving axis of the punch in consideration of the clearance 9b, and then, the wire-cut electro-discharge forming work is applied to the blank 3. After that, the punch 8 and the die 9 are removed from the blank 3, and are set again to the plate 1 and the plate 2 respectively.
