The dimension from the outside of the bottom die 37 of the movable head 11 to the outside of the bottom die 37 of the fixed head 9 becomes the bottom dimension of the plate-shaped material W after bending.
The head moving motor 16 is driven to move the movable head 11 to X2
Move and position in the axial direction. Then, the material W placed on the table 19 is carried into an appropriate position on both bottom dies 37.

Next, as shown in FIG. 7A, in each of the movable head 11 and the fixed head 9, the piston rod 33 of the top die lifting / lowering cylinder 31 is shortened so that the bottom surface of the top die 29 becomes horizontal. At the same time, the piston rod 25 of the clamp beam elevating / lowering cylinder 27 is also gradually shortened, and the clamp beam 23 is lowered to a position where the bottom surface of the top die 29 sandwiches and fixes the material W between the bottom die 37 and the bottom die 37. Let it.

Next, as shown in FIG. 7B, the piston rod 45 of the bend beam driving cylinder 43 is extended, and the bend beam 39 is rotated approximately 90 ° upward from below the pass line L. At this time, the bend beam 39 on the fixed head 9 side rotates in the rotation direction a, and the bend beam 39 on the movable head 11 side rotates in the rotation direction b. As a result, the bend beam 39 pushes up a portion of the lower surface of the raw material W from the outside of each of the bottom dies 37 to each end thereof, and performs bending until it becomes vertical. Then, the two bending support bars 47 attached to the bend beam 39 rotate from the horizontal direction to the vertical direction while supporting the material W pushed up by the bend beam 39 so as not to fall down.

Thereafter, each of the bend beam 39, the clamp beam 23, and the top die 29 is returned to a predetermined position and state by the reverse operation of the above operation. By this operation, the bending support bar 47 supporting the bending rising portion of the bending workpiece S returns to the horizontal state.

When the bent workpiece S is loaded on the carriage 53 of the bent workpiece transport device 3, the unloading conveyor 13 and the loading conveyor 63 are stopped. Next, as shown in FIG. 8B, the wheel 59 is rotated by driving the truck moving motor 61 of the truck 53, and the truck 53 is moved on the rail 52 by X.
Move to the next stroke position in one direction. At this time, trolley 5
The bent workpiece S on 3 is conveyed in a state where it is supported by the support bar 69 so that the bent rising portion does not fall. When the carriage 53 has moved to the position of the next step, the drive of the carriage movement motor 61 is stopped and the carriage 53 is stopped. The bent workpiece S is now taken out of the bent workpiece transport device 3 by the operator.

When the bent workpiece S is discharged from the carriage 53, the carriage moving motor 61 is driven in the reverse direction, and the carriage 53 is returned on the rail 52 to the bent workpiece unloading position of the bending apparatus 1. Then, the process waits for the next bent workpiece S to be transported.

As described above, according to the bent work conveying system of the present embodiment, after the plate material W is bent by the bending apparatus 1, the bent work S is automatically formed without manual operation. The workpiece can be transported from the bending apparatus 1 to the next stroke position by the bending workpiece transport apparatus 3. In addition, the bent workpiece S can be transported to the next stroke position in a state where the bent rising portion is supported so as not to fall.
