The electrical control system 2 is equipped with a PLC control center to regulate the coordinated operation of components such as cylinders, motors, and induction switches.

[0018] The inner liner fixing device 3 secures and installs the inner liner 7 on the device, and also positions the inner liner 7 in the height direction. The inner liner fixing device 3 includes a positioning frame 31, a positioning block lifting mechanism 32, and a positioning block 33. The positioning frame 31 is fixed to the frame 1, the positioning block lifting mechanism 32 is vertically mounted on the positioning frame 31, and the positioning block 33 is mounted on the positioning block lifting mechanism 32. The positioning block lifting mechanism 32 can be a cylinder.

The clamping and lifting mechanism 41 is vertically mounted on the frame 1, and the pressure plate 42 is mounted on the clamping and lifting mechanism 41. The clamping and lifting mechanism 41 can be a cylinder.

[0020] The heat exchanger positioning device 5 positions the heat exchanger 8 to ensure consistent length of the workpiece folds. Located on one side of the heat exchanger clamping device 4, the heat exchanger positioning device 5 includes a push plate 51, a push plate translation mechanism 52, and a base plate 53. The base plate 53 is slidably mounted on the frame 1 via guide rails. The push plate translation mechanism 52 is horizontally mounted on the base plate 53, and the push plate 51 is mounted on the push plate translation mechanism 52. The push plate translation mechanism 52 can be a cylinder, a servo electric cylinder, or similar device.

[0021] The longitudinal positioning device 9 achieves the longitudinal positioning of the heat exchanger 8. The longitudinal positioning device 9 includes a support 91 and a support translation mechanism 92. The support translation mechanism 92 is mounted on the frame 1, and the support 91 is mounted on the push plate translation mechanism 52.

[0024] (2) Place the heat exchanger 8 on the pressure plate 42 of the heat exchanger clamping device 4, with the rear end of the heat exchanger 8 resting against the backrest 91.

[0025] (3) The push plate translation mechanism 52 pushes the push plate 51, and the push plate 51 pushes the heat exchanger 8 to move laterally to the bending position; the zero point coordinate can be preset in the system, and the heat exchanger 8 can be pushed to the zero point position to stop; or a backing can be set, and the push plate 51 pushes the heat exchanger 8 to move laterally to the backing, which means that the bending position has been reached.

[0026] (4) Power is provided by clamping and lifting mechanism 41, clamping and lifting mechanism 41 lifts pressure plate 42 upward, pressure plate 42 presses heat exchanger 8 and inner liner 7 upward, so as to achieve the firm fixation of heat exchanger 8 and inner liner 7.

[0027] (5) The roller lifting mechanism 61 pushes the roller 62 upward. The roller 62 starts to push the two sides of the heat exchanger 8 along the outer wall of the inner liner 7 to the set position.
