Abstract

PURPOSE: To prevent taking out of two plates by forming minute embossment on each blank and shifting the position of embossment formation in adjoining blanks.
CONSTITUTION: When shearing work is performed, a projection 20 of a rotating body 18 on the right can enter a concave part 16, and embossing is made when a pad 6 applies pressing force to a blank W. At this time, a projection 19 of a left side rotating bpdy 19 does not enter a concave part 17 and embossing is not made. When an upper die 5 goes up after shearing work a ratchet pawl 26 catches a pawl of a ratchet wheel 23 to rotate a rotating shaft 22 by 45°, and the projection 20 of the rotating body 19 comes to a position where it can enter the concave part 17. In the next shearing, embossing is made on the left side, facing the direction of advance, of the blank W. Thus, sheared blanks W on which the positions of embossment are deviated from each other are piled in a pallet 13. Accordingly, spaces are formed between the blanks W, and taking out of two plates can be prevented.
