Abstract

PURPOSE:To punch, cut and V-bent small-sized workpieces in a press machine by punching each small-sized workpiece leaving a part of each circumference and then V-bending each small-sized workpiece retaining it in a large-sized work. CONSTITUTION:A trimming die 47 for punching and cutting the work is fitted at the corresponding position to an upper turret and a lower turret. The trimming die 47 is composed of an upper die 51 with a punch chip 49 and a lower die 55 with a die 53. A V-bending punch 73 and a V-bending die 75 are mounted as V-bending dies at another corresponding position to the upper turret and the lower turret. Pressing is carried out by the upper and lower dies 51, 55 and prescribed small-sized workpieces 45 are punched out of a large sheet work 7 leaving a part 71 of each circumference. Then, the small-sized workpieces 45 connected with the large-sized sheet work 7 are put on a V- bending die 75 and a punch 73 is lowered to perform V-bending. Thereafter, the V-bent small-sized workpieces 45 are separated by striking from the large- sized sheet work 7.
