Abstract

PROBLEM TO BE SOLVED: To unnecessitate finishing for flaws caused by bending which is executed in a conventional method, to decrease a man-hour and also to improve quality by not imparting flaws caused by bending to a stock like bending at the time of using a lower die having a V shaped groove because the sliding-in of the stock is eliminated by the reason that two bending blades are bent in the connected surface. SOLUTION: This device is constituted by connecting a bending blade 1 to a bending blade 2 with a hinge 3 and combining them with a lower die 4 having a V shaped groove. At the time of using the device, the bending blade of an upper die is die matched with the device and set to a bending machine, and a stock is set on the device. When the bending blade of the upper die is lowered, brought into contact with the stock and further lowered, the bending blade 1 and the bending blade 2 are bent in the connected surface together with the stock and fixed with the lower die 4 having the V shaped groove. When forming is completed and the bending blade of the upper die is lifted, the bending blade 1 and the bending blade 2 are flatened as they were on the lower die 4 having the V shaped groove.

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.
