摘要： PURPOSE:To reduce a dead zone of a press machine by constituting so that an upper die holder and a lower die holder contact with each other by an inclined plane which becomes low in front. CONSTITUTION:An upper die holder 17U slides and moves correctly in the inclined direction of an inclined plane 27 against a lower die holder 17L. The first link 41 is fitted freely rockably to a yoke-shaped bearing 37 through a shaft pin 39, the tip of the first link 41 is connected to the second link 43 by a shaft pin 45, and the other end of the second link 43 is connected to the upper holder 17U by a shaft pin 47. Also, the tip of a piston rod 55 of a fluid pressure cylinder 53 which is freely rockable around a supporting shaft 51 provided on a machine base 49 of a press machine is connected to a connecting shaft pin 45 of the first link 41 and the second link 43 through the third link 57. When working is required near the side edge of a plate material, the upper face of the adjacent die which might cause an interference is lowered by operating the fluid pressure cylinder 53.

摘要： PURPOSE:To reduce the arrangement time by subjecting the plate to desired working with one side plate working machine, then approaching the other plate working machine to the above machine and subjecting the above plate to desired working with the other plate working machine. CONSTITUTION:At the time the plate working is executed to a plate W, specially, a large plate with plate working machine 3, 5 which are arranged confronting each other, the plate W is subjected to the desired working at first with one side plate working machine 3. Next, the other plate working machine 5 is approached to the one side plate working machine 3 and the plate W is unclamped from a workclamp 35 of the one side plate working machine 3. On the other hand, after clamping the plate W with a workclamp 81 of the other plate working machine 5, the part of the above plate which is not worked with the one side plate working machine 3 is subjected to desired working. In such a way, the reduction of arrangement time and the working with high accuracy are realized.

摘要： PURPOSE:To reduce the number of replacements of metallic dies and to perform the replacement simply by providing a hinge type storing part and fixed type storing part and by keeping the hinge type and fixed type separately. CONSTITUTION:When three units B, C, D of metal dies among metal dies A, B, C, D, E... arranged to a bending machine 1 are unnecessary, the hinge type A of the endmost part is slid and introduced to a hinge type storing part 7 of a metal die replacing device 5 and kept temporarily. The metal dies B-D which became unnecessary are then slid and introduced to a fixed type storing part 9 of the device 5. The hinge type A is then taken out again from the storing part 7 and set so as to adjoin the metal die E remaining at a metal die fitting part 3 of the bending machine 1. In this case the positioning of the metal die is performed based on the reference line R/L of the metal die fitting part 3. In th is way, a new metal die having a hinge type A at both ends for a box bending is combined by shorting to the prescribed width.
