PURPOSE:To make a press adaptable quickly to changed parts without changing dies even if the parts are changed by disposing various dies movably on a base plate and moving the various dies by a driving device which moves linearly. CONSTITUTION:A servocontrol motor 5 is operated in order to part a boring die 1 to a notching die 2 in the case of manufacturing parts of a fresh lot. A metallic plate is then inserted to the die 1 and a reference hole is bored and a notch is blanked by the die 2; further the plate is pressed by a shape blanking die. If there is a need for exchanging the blanking die, the 1st shape blanking die is transferred by a cylinder to the outside of the block and the 2nd shape blanking die 4 is moved to and fixed in the home position by a cylinder 7b, etc., then the rough material of the prescribed parts is blanked. |
