[0031] In the embodiment, the pushing mechanism comprises a motor 2 and a sliding frame 3. When the sliding frame 3 needs to slide, the motor 2 drives the screw rod 4 to rotate directly inside the main body 1, and the sliding frame 3 slides inside the main body 1 through the screw hole 15 and the screw rod 4. When the sliding frame 3 slides, the limiting block 16 on the sliding frame 3 is connected with the limiting groove 14 in the main body 1, and the roller 5 at the bottom of the sliding frame 3 slides in the sliding groove 13, so that the sliding frame 3 slides on the main body 1 more stably.

[0032] In the embodiment, the clamping mechanism comprises a first hydraulic cylinder 6 and a mounting piece 7. When in use, the mounting piece 7 and the clamping piece can be replaced according to the size of the workpiece to be bent. When mounting, the mounting piece 7 is mounted on the first connecting block 17 of the first hydraulic cylinder 6 through the fixing bolt 8. When the position of the mounting piece 7 is fixed, the clamping plate 9 is mounted on the mounting piece 7. When mounting, the clamping block 19 is pulled first, so that the clamping block 19 can extrude the spring 20 mounted in the mounting piece 7. Then, when the mounting block 21 on the clamping plate 9 is connected with the mounting groove 23 on the mounting piece 7, the clamping block 19 is released, and the extruded spring 20 directly pushes the clamping block 19 into the clamping hole 22 in the mounting piece 7, so that the position of the mounting piece 7 is fixed.

[0033] In the embodiment, the bending assembly comprises a hydraulic motor 10 and a second hydraulic cylinder 11.

When the workpiece is fixed and the position is controlled by the sliding frame 3, one end of the workpiece can be placed on the main rod 24 on the rotary disc 12. The second hydraulic cylinder 11 installed in the rotary disc 12 drives the second connecting block 18 to clamp one end of the workpiece. Then, the hydraulic motor 10 drives the workpiece to be bent. After bending, if it needs to be bent again, the first hydraulic cylinder 6 drives the workpiece to be released, but one end of the workpiece is fixed on the rotary disc 12. Then, the motor 2 drives the sliding frame 3 to slide a certain distance, and then the workpiece is clamped again. The second hydraulic cylinder 11 on the rotary disc 12 releases the workpiece, and then resets. The sliding frame 3 slides on the main body 1 again, so that the workpiece can be repeatedly bent in the same way.
