Abstract
PURPOSE: To accurately work holes, protrusions, etc. on the peripheral surface of the captioned work without giving any scores to the work itself by actuating a punch from the inner side of the work toward its outer side in the state that the entire circumference of the work is perfectly gripped.
CONSTITUTION: This press working device is mounted on the bolster 3 of a conventional press machine; a blank C' is put into the blank loading hole of a die 1 with its axial line direction being made horizontal; a rod 20 is inserted into the center of the blank C' by a cylinder 21; a locating rod 24 is inserted to the rod 20 by a cylinder 25 to fix the rod and a punch 23 is opposed to the inside surface of the blank C'. A cylinder 9 is actuated to press a gear 7 to the blank C' and grip the same by a piston 10. When in this state the press machine is operated, a ram 15 descends and abuts against a punch holder 16, causing a spring 17 to be pushed downward against a spring 17 and causing the punch 23 to act upon the inside surface of the blank C', thereby blanking a hole. The ram 15 is moved upward to reset the holder 16 to the original position, after which a rack 8 is operated to turn the gear 7 at the required angle and turn the blank C', thence next hole opening is performed.
