The bending angle is too large or too small, resulting in inconsistent bending effects of the air-conditioning copper tubes produced in each batch, resulting in uneven product quality. The slider 10 is moved by the handle 12 according to the scale line 14, and the position of the slider 10 is fixed with the locking screw 11, and the servo motor 4 is started. The output end of the servo motor 4 drives the connecting plate 5 to rotate, thereby rotating the rotating shaft 6 and the bending roller 7 to bend the copper tube. The rotating shaft 6 drives the electrode sheet 9 to slide in the annular groove 8. After bending to the required angle, the electrode sheet 9 generates an electrical signal when it contacts the electrode plate 13 and is transmitted to the control panel 35. The control panel 35 controls the warning light 15 to turn on and the servo motor 4 to turn off. The warning light 15 prompts the operator to complete the bending operation, thereby achieving precise adjustment of the copper tube bending angle, ensuring the consistency of the copper tube bending, and improving the processing quality of the copper tube.

[0024] See also Figure 1 、 2As shown in , 4, and 5, a fixed clamping block 16 is fixed to one end of the top side of the main board 1, and a driving motor 17 is installed on one side of the main board 1. A threaded rod 18 is installed on the output end of the driving motor 17, and a slide groove 19 is provided inside the main board 1. A dynamic clamping block 20 is slidably installed inside the slide groove 19, and a screw hole is provided inside the bottom end of the dynamic clamping block 20. One end of the threaded rod 18 passes through the screw hole and is rotatably installed on one side inner wall of the slide groove 19; during operation, since the surface of the copper tube is too smooth, the copper tube will slide during the bending process of the bending column, which will affect the bending effect of the copper tube. After the transportation is completed, the driving motor 17 is started, and the driving motor 17 drives the threaded rod 18 to rotate, which will cause the dynamic clamping block 20 to move along the slide groove 19, and together with the fixed clamping block 16, it can achieve a firm clamping of the copper tube, ensuring that the copper tube will not be displaced or shaken during the bending process, thereby ensuring the stability of the copper tube during bending.

The spring 32 is sleeved on the outer wall of the guide rod 30, and a connecting shaft 33 is rotatably installed between the movable blocks 31, and an auxiliary roller 34 is assembled on the outer wall of the connecting shaft 33; during operation, in order to ensure that the copper tube enters the bending area accurately and improves production efficiency, the conveying motor 25 is started, and its output end drives the driving wheel 26 to rotate, and drives the driven wheel 23 to rotate through the belt 27, so that the conveying roller 22 rotates, and the conveying roller 22 cooperates with the auxiliary roller 34 to smoothly deliver the copper tube into the bending area, thereby improving the bending efficiency of the copper tube. During the conveying process, if the copper tube generates pressure on the auxiliary roller 34, the movable block 31 will slide along the guide rod 30 in the rectangular groove 29, compressing the spring 32, playing an adaptive role, enhancing the stability and smoothness of the copper tube conveying, and preventing it from deflecting during the conveying process.

[0026] Working principle: When the conveying motor 25 is started, its output end drives the driving wheel 26 to rotate, and drives the driven wheel 23 to rotate through the belt 27, thereby rotating the conveying roller 22. The conveying roller 22 cooperates with the auxiliary roller 34 to smoothly deliver the copper tube into the bending area, thereby improving the bending efficiency of the copper tube.

[0027] After the conveying is completed, the driving motor 17 is started, and the driving motor 17 drives the threaded rod 18 to rotate, which causes the movable clamping block 20 to move along the slide groove 19, and together with the fixed clamping block 16, firmly clamps the copper tube to ensure that the copper tube will not be displaced or shaken during the bending process, thereby ensuring the stability of the copper tube during bending;

[0028] Move the slider 10 through the handle 12 according to the scale line 14, and fix the position of the slider 10 with the locking screw 11, start the servo motor 4, and the output end of the servo motor 4 drives the connecting plate 5 to rotate, thereby rotating the rotating shaft 6 and the bending roller 7 to bend the copper tube. The rotating shaft 6 drives the electrode sheet 9 to slide in the annular groove 8. After bending to the required angle, the electrode sheet 9 generates an electrical signal when it contacts the electrode plate 13 and transmits it to the control panel 35. The control panel 35 controls the warning light 15 to turn on and the servo motor 4 to turn off. The warning light 15 prompts the operator to complete the bending operation, thereby achieving precise adjustment of the copper tube bending angle, ensuring the consistency of the copper tube bending, and improving the processing quality of the copper tube.
