Abstract

PURPOSE:To obtain a folding die that can be used without changing dies according to the change of length of upper dies constituting an upper die of an upper die body attached to the lower end of the ram of a folding line, a number of intermediate blocks fitted in the lower part allowing free inversion and corner blocks attached to both ends of the group of intermediate blocks. CONSTITUTION:The longer side 3 of a work 1 the shorter side 2 of which is bent to channel-shape beforehand is held by an upper die 11 and a lower die 12, and the turnup is bent by operation of a movable die 13. Then, a ram 10 is raised once to project the work 1 by the length of stroke of a side end part 6. After holding the work 1 by lowering the ram 10 again, the work is bent to channel-shape by operating the movable die 13. In the case where the length of the work changes, number of the first intermediate blocks 16 and the second intermediate blocks 17 is increased or decreased. To reduce, for instance, the upper die 17, after inverting the two blocks 16, 17 successively or simultaneously, left and right corner blocks 15, 15 are shifted to the center by rotating a supporting rod 19 and a screw cylinder 19a.
