PURPOSE:To absorb errors in working dimension of each member and to make the production and work easy by providing plural sets of fixed wedges and mobile wedges with separation between upper and lower plates and by providing a cylinder for sliding to each mobile wedge. CONSTITUTION:The air is fed to the side of a cylinder room of each mobile wedge 33 and the mobile wedge 33 is slid and brought into contact with the inclined face of a fixed wedge 31 which is opposed respectively. When the position of an upper plate 19 is fixed as mentioned above, the position of the bottom part of a groove 25 for working supported via a supporting pin 17 is decided as well and the depth of the groove 25 is made to be decided and the bending angle of a material too is regulated. Then a bending rod is descended with respect to the die device 13 with driving a ram and the prescribed bending work is made on the material. |
