形状の曲げ加工品を容易に得ることができる。As described above, according to the present invention, the movable mold is displaced when the work passing through the through holes of the fixed mold and the movable mold is moved in the longitudinal direction and bent. The whole work cross-sectional shape can be bent into the shape obtained by the displacement, and further, by displacing the movable piece portion via the driving means, the work cross-sectional shape can be obtained by the displacement. Can be partially bent. As a result, the work W
The entire and a part of the cross-sectional shape can be subjected to bending in one bending step, and bent products having various shapes according to applications can be easily obtained.

きる。In the case where the movable piece portion has a conduction hole for conducting a part of the work in the cross-sectional shape, the conduction hole also serves as a part of the work conduction hole of the movable mold. Is
If the work is conducted to the conduction hole of the movable piece, a part of the work is held between the movable pieces, and the entire bending and partial bending of the work can be reliably performed.
