[0023] In this embodiment, when bending the evaporator heat exchange tubes, such as Figure 1 As shown, the mounting plate 2 and the base frame 1 are parallel at this time. First, the bending mechanism is started to rotate the mounting plate 2 clockwise by 90 degrees, which facilitates the placement of the evaporator heat exchange tube between the bending plate 3 and the fixing part 5. Then, the evaporator heat exchange tube is placed on the bending plate 3. At this time, the first telescopic rod 4 is started to drive the fixing part 5 to fix the evaporator heat exchange tube placed on the bending plate 3. Then, the bending mechanism is started to rotate and bend the clamped and fixed evaporator heat exchange tube. A controller is set on one side of the device. The controller can control the operation of the whole. The specific bending angle can be controlled by the controller. The working principle of the controller is existing technology and will not be described in detail here. At the same time, before the bending of the evaporator heat exchange tube, the straightening mechanism can be started by the controller to straighten the evaporator heat exchange tube, which can improve the aesthetics and effect of the subsequent bending of the evaporator heat exchange tube. The whole device can bend the evaporator heat exchange tube and straighten the evaporator heat exchange tube before bending, which improves the effect and aesthetics of the bending of the evaporator heat exchange tube.

[0024] In a further preferred embodiment of the present invention, the pipe bending mechanism includes: a first servo motor 6 fixedly mounted on the base frame 1; and a mounting shaft 7 rotatably mounted on the base frame 1, wherein the bottom end of the mounting shaft 7 is fixedly connected to the output shaft of the first servo motor 6, and the top end of the mounting shaft 7 is fixedly connected to the bottom of the mounting plate 2.

[0025] In this embodiment, after the fixing member 5 fixes the evaporator heat exchange tube placed on the bending plate 3, the controller starts the first servo motor 6 to drive the mounting shaft 7 to rotate. The center positions of the mounting shaft 7 and the bending plate 3 are on the same vertical line. The rotating mounting shaft 7 drives the bending plate 3 to rotate, and the rotating bending plate 3 drives the evaporator heat exchange tube to bend along the bending plate 3, thereby completing the bending operation of the evaporator heat exchange tube.

[0026] In a further preferred embodiment of the present invention, the straightening mechanism includes: a placement frame 8 fixedly installed on the base frame 1; a plurality of second telescopic rods 9 disposed on the placement frame 8, and a plurality of mounting frames 10 fixedly installed on the output shafts of the plurality of second telescopic rods 9; and a plurality of straightening rollers 11 rotatably installed on the plurality of mounting frames 10, the straightening rollers 11 being used to straighten the heat exchange tubes of the evaporator.

[0027] In this embodiment, when placing the evaporator heat exchange tubes, the evaporator heat exchange tubes are first placed between the placement racks 8. Straightening rollers 11 are provided on the upper, lower, left, and right sides of the placement racks 8. According to the diameter of the evaporator heat exchange tubes, multiple second telescopic rods 9 are activated by the controller to drive the upper, lower, left, and right straightening rollers 11 on the placement racks 8 to move relative to each other. The upper and lower straightening rollers 11 contact and limit the upper and lower side walls of the evaporator heat exchange tubes, and the left and right straightening rollers 11 contact and limit the left and right sides of the evaporator heat exchange tubes. When feeding the evaporator heat exchange tubes, the evaporator heat exchange tubes can be straightened well under the action of multiple straightening rollers 11, improving the effect and aesthetics of the bending process of the evaporator heat exchange tubes.

[0028] In a further preferred embodiment of the present invention, the placement rack 8 is provided with an adjustment mechanism for adjusting the usage position of one of the mounting racks 10. The adjustment mechanism includes: a third telescopic rod 12 fixedly installed on the placement rack 8; and a connecting frame 13 fixedly installed on the output shaft of the third telescopic rod 12. The connecting frame 13 and the second telescopic rod 9 are fixedly connected.

[0029] In this embodiment, when it is necessary to adjust the position of the straightening roller 11 above the placement rack 8, the controller can be used to activate the third telescopic rod 12 to move the connecting rack 13, thereby facilitating the placement of the evaporator heat exchange tube.

[0030] In a further preferred embodiment of the present invention, the base frame 1 is provided with a clamp 14 for clamping the evaporator heat exchange tube, and the base frame 1 and the clamp 14 are provided with a feeding mechanism for feeding the evaporator heat exchange tube clamped by the clamp 14.

[0031] In this embodiment, the evaporator heat exchange tube can be clamped by the clamp 14.

[0033] In this embodiment, when using the feeding mechanism, the second servo motor 16 is started to drive the lead screw 17 to rotate. A limit rod is provided on the frame 15. The limit rod and the drive block 18 are slidably connected. The limit rod limits the drive block 18, so that the lead screw 17 stably drives the drive block 18 to move, thereby driving the clamp 14 to move and feed the clamped evaporator heat exchange tube.

[0034] In a further preferred embodiment of the present invention, an installation groove is provided on the mounting plate 2, a slide rod 19 is fixedly installed in the installation groove, and a slider 20 is fixedly installed at the bottom of the fixing member 5, and the slider 20 and the slide rod 19 are slidably connected.
