Further, the operation ends of the feeding manipulator 9-2 and the discharging manipulator 9-1 are both in a vacuum chuck 17 structure. Because the workpiece 12 material to be bent is often plate-like in structure and non-magnetic. In order to ensure that the workpieces 12 of each material can be lifted by the manipulator, the operating end adopts a vacuum chuck 17 structure, so that the workpieces 12 can be lifted, and the balance of the workpieces 12 can be maintained when the workpieces 12 are lifted. The robot can move left and right and up and down, and can transfer the workpiece 12. The robot is a common structure and will not be described in detail here.
Further, a feeding table 20 is arranged beside the feeding manipulator 9-2, the feeding manipulator 9-2 grabs and moves the workpiece 12 to be bent on the feeding table 20 onto a lower template 28 on the base, and places the workpiece 12 through a positioning block 26. The movable blanking car 7 is arranged beside the blanking manipulator 9-1, and the blanking manipulator 9-1 takes down the workpiece 12 after the bending of the lower template 28 and places the workpiece on the blanking car 7. The bracket 1 is provided with a side opening for the feeding and discharging of the discharging car 7. Since the workpiece 12 after the bending is completed cannot be placed neatly, it is placed in the blanking car 7. After the bent workpiece 12 in the blanking car 7 is full, the blanking car 7 is pulled out from a side opening on the bracket 1. Further, the discharging car 7 is provided with a handle, so that the discharging car 7 can be conveniently moved.
The foregoing description is directed to the preferred embodiments of the present invention, but the embodiments are not intended to limit the scope of the invention, and all equivalent changes or modifications made under the technical spirit of the present invention should be construed to fall within the scope of the present invention.
