ABSTRACT:
A bending apparatus includes: an upper bending die 63U for downward bending both ends of the plate material gripped between upper and lower plates 59U and 59L provided on upper and lower frames 35U and 35L, respectively and a lower bending die 63L for upward bending both ends of the same plate material; and upper and lower bending mechanisms each including a link mechanism for moving the upper bending die or the lower bending die in both upward or downward direction, respectively. In the bending apparatus according to the present invention, since the upper and lower bending mechanisms 61U and 61L are constructed by a link mechanism, respectively, it is possible to move the upper or lower bending die 63U or 63L far away from the bending position of the plate material W.
