When the backing plate abuts against the end face of the workpiece, the clamping blocks clamp both sides of the workpiece, which can prevent the misalignment between the fins of the workpiece during bending and improve the yield rate. The first rack is provided with a detection mechanism. During detection, the pushing mechanism pushes the workpiece to one side of the first positioning mechanism. The first positioning mechanism positions the workpiece, and then the detection mechanism measures the dimensions (such as length or thickness) of the workpiece. After passing the detection, the first lifting mechanism descends, and the first positioning mechanism no longer blocks the workpiece. The pushing mechanism is started again to push the workpiece to the bending machine, thus realizing the detection and feeding processes and reducing the defective rate.

The direction from the first bending mechanism 4 to the second bending mechanism 5 is defined as the transverse direction, or in other words, the length direction of the workpiece is defined as the transverse direction, and the direction horizontally perpendicular to the transverse direction is defined as the longitudinal direction. The transverse and longitudinal directions are only defined for the convenience of description.

[0051] The bending system 10 includes a first frame 1.

The second shifting frame 51 and the second bending mounting frame 52 achieve sliding through the guide rail and guide groove. The second lifting power device 70 drives the second bending mounting frame 52 to move up and down.

The second rotating rod 57 will rotate following the second rotating shaft 54. The upper end of the second linkage frame 56 is fixed on the second rotating shaft 54. A clamping plate 571 capable of clamping the workpiece is arranged on the second rotating rod 57.

The backing plate assembly 7 includes a backing plate transverse movement frame 71 driven by the backing plate transverse movement power device 35 to move transversely on the first frame 3, a backing plate mounting frame 72 slidably arranged up and down on the backing plate transverse movement frame 71, a backing plate lifting power device 73 for driving the up and down movement of the backing plate mounting frame 72, a backing plate 74 rotatably arranged on the backing plate mounting frame 72 and capable of leaning against the workpiece, and a backing plate rotation driving device 75 for driving the rotation of the backing plate 74.

The backing plate rotation driving motor 751 can drive the rotation of the backing plate rotating shaft 721 through a gear or a synchronous belt. The up and down movement of the backing plate transverse movement frame 71 and the backing plate mounting frame 72 is realized through a guide rail and a guide groove. The backing plate lifting power device 73 can be realized through a screw nut seat, and of course, it can also be realized by the pushing of a cylinder. Two clamping blocks 76 longitudinally arranged opposite to each other for clamping both sides of the workpiece are provided on the backing plate 74, and a clamping block power device 77 for driving the two clamping blocks 76 to move relatively closer or farther away. The clamping block power device 77 can be realized through a screw rod and two nut seats with different thread directions.

[0056] On the follow-up mechanism 50, there is a second positioning mechanism 61 for positioning the workpiece and a second lifting mechanism 62 for driving the second positioning mechanism 61 to lift on one side away from the feeding system 20. The second positioning mechanism 61 positions the workpiece when the feeding system 20 feeds the workpiece to the follow-up mechanism 50. After the workpiece is bent, the second positioning mechanism 61 descends, and the workpiece can be pushed out by the feeding system 20.

On the positioning mounting frame 614, there is a pulley 616 that can slide into the inclined slot 621 when the positioning mounting frame 614 longitudinally moves. Since the inclined slot 621 is inclined downward, after the positioning mounting frame 614 slides into the lower end of the inclined slot 621, the positioning mounting frame 614 will sink.

After passing the inspection, the positioning rod moves downward, and the pusher rod 227 pushes the workpiece onto the follow-up mechanism 50.The detection structure 23 includes a movable detection rod 231 provided on the second rack 2, a fixed detection rod 232 arranged transversely opposite and spaced apart from the sliding detection rod 23, a first detector 233 provided on the sliding detection rod 231, a second detector 234 provided on the fixed detection rod 232, and a movable detection driving device 235 for driving the movement of the sliding detection rod 231.
