The bending blade 1 (1) and the bending blade 2 (2) are connected by a hinge (3) and combined with the V-groove lower mold (4). When the present invention is used in the above structure, the upper mold bending blade (6) and the present invention are matched with each other and set on a bending machine, and the material (7) is set on the present invention. (FIG. 3) Bending blade 1 (1) and bending blade 2 when upper bending blade (6) descends and touches material (7), and when upper bending blade (6) further descends.

担が少ない。According to the present invention, the bending blade 1 (1) and the bending blade 2 (2) are bent at the connection surface, so that the material (7) does not slip and the material is not bent. This eliminates the need to finish bending scratches, thus reducing man-hours and improving quality. Normally, since the bending blades (1) and (2) are flat, it is easier to clean the mold than when only the lower V-groove mold (4) is used. The life of the V-groove lower mold (4) is extended because the material (7) does not directly contact the V-groove lower mold (4). Also, if the material (7) is crushed due to an operation mistake or the like, the mold may be damaged, but the bending blade 1 (1) or the bending blade 2 (2) is located between the V-groove lower mold (4). The possibility of directly damaging the expensive V-groove lower mold (4) is low and the bending blade 1 is inexpensive.
(1) Or the bending blade 2 (2) only needs to be replaced, so that the burden is small.
