Abstract

PURPOSE: To let bending having arbitrary plate thickness and arbitrary serration be accomplished effectively in one process by making a lower die vertically movable and combining the auxiliary base spring-energized to an upper die.
CONSTITUTION: According to the bending width of the plate material 1 to be worked, the combination of an upper die 16 is contained in an upper die block 15 and is sucked and fixed to a magnet 17. A lower die 12 is protruded to an arbitrary height from an auxiliary base 13 by turning a knob 11 thereby moving an inclined block 10. The entire part of the lower die block 7 is moved by turning a longitudinal feed knob 9 to set the specified gap. The plate material 1 is placed on the lower die 12. When the upper die auxiliary base 20 is lowered by exerting external force to a die set 14 to hold the plate material 1 on the lower die 12, then the upper die auxiliary base 20 ascends in the block 15 while being applied with pressing force by a spring 19. Hence, the upper die 16 automatically protrudes below the auxiliary base 20 and the plate material 1 is thus bent.
