[0069] In the heating chamber 21, the temperature in the heating chamber 21 is monitored by the temperature sensor 25, the driving motor 221 and the heating wire 223 are started, the heating wire 223 is heated, and the driving motor 221 drives the vortex impeller 222 to rotate; the rotation of the heat delivery module 22 drives the air in the drainage chamber 231 to move to the middle of the vortex impeller 222 through the cooperation of the lower guide plate 241, and moves upward from the middle of the vortex impeller 222, taking away the heat of the heating wire 223 in the hollow groove 234 in the process; the heated airflow passes through the guide hole 243 after being guided by the upper guide box 242 , and passes through the heating circular hole to exchange heat with the pipeline to heat the pipeline; then the airflow flows into the reflux chamber 232 through the reflux hole 244, and returns to the drainage chamber 231 through the reflux baffle 245 and the reflux channel 233, so as to achieve uniform and rapid dispersion of the airflow, making the temperature in the heating chamber 21 more balanced; so that the temperature measured by the temperature sensor 25 is basically consistent with the temperature in the copper tube 41, which is convenient for temperature control, thereby ensuring the temperature balance of the heating pipeline, and thus improving the processing quality; the heated pipeline is insulated by the insulation sleeve 3, so that the bend maintains an appropriate temperature before processing;

[0070] Start the electric push cylinder 524 and the synchronous belt 127; the pipeline is transported to the left through the synchronous belt 127, and at the same time, the electric push cylinder 524 drives the movable support frame 523 to move horizontally under the cooperation of the second slide 521 and the third guide rail 522, and the movable support frame 523 moves horizontally to drive the fixed plate 431, the lower guide sleeve 433, the auxiliary clamping cylinder 434 and the upper guide sleeve 435 to move horizontally, thereby driving the pipeline to move to the left together with the cooperation of the synchronous belt 127; in this process, the outer diameter of the liner ring sleeve 423 is consistent with the inner diameter of the copper tube 41, and the guide spring 422 can be changed by replacing the guide spring 422 or changing the expansion and contraction amount of the guide spring 422. The inner diameter of the material spring 422 is adapted to pipes of different sizes; at the same time, the center of the material spring 422 is always consistent with the center of the copper pipe 41 through the inner lining ring 423 outside the material spring 422; thus, the cooperation between the material spring 422 and the inner lining ring 423 facilitates the pipe to be concentric with the copper pipe 41; and when the pipe moves to the left, the material spring 422 is driven to vibrate slightly, thereby cleaning the dust outside the pipe; the dust moves to the outside of the copper pipe 41 through the material spring 422, the inner lining ring 423 and the heating round hole, thereby preventing the dust from accumulating in the copper pipe 41;

[0071] Then the auxiliary clamping cylinder 434 drives the lower die 535 to move upward, so that the movable plate 533 and the lower die 535 no longer clamp the pipe; the electric push cylinder 524 drives the movable support frame 523 to reset, so that the pipe to be bent moves to the left side of the upper die 534 and the lower die 535; then the auxiliary clamping cylinder 434 is started again to clamp the pipe through the upper guide sleeve 435 and the lower guide sleeve 433; at this time, the support spring 144 is located in the pipe at the bending die module 53, so as to support the inner pipe and prevent the pipe from being deformed during the bending process;

[0072] When bending the pipe, the upper guide sleeve 435 is driven by the auxiliary clamping cylinder 434 to cooperate with the lower guide sleeve 433 to clamp the pipe, so as to prevent the pipe from rotating with the rotating disk 515, thereby ensuring the bending accuracy;

[0073] The rotating motor 512 drives the second gear 514 to rotate through the first gear 513, and the second gear 514 drives the rotating disk 515 and the fixed support frame 516 to rotate, thereby driving the movable support frame 523 to rotate through the second slide 521 and the third guide rail 522; so that the upper mold 534, the lower mold 535 and the bending rod 546 on the movable support frame 523 for bending are moved to the angle where the pipe is to be bent;

The bending rod 546 drives the pipe to bend in cooperation with the bending groove 536 between the upper die 534 and the lower die 535, so as to realize the bending of the pipe. In this process, the supporting spring 144 is used to support the pipe in order to prevent the pipe from being deformed. After the bending process, the cooling pipe 71, the vortex tube 73 and the cooling nozzle 72 are used to spray cold air onto the bent pipe to accelerate the cooling and shaping of the pipe.

[0075] After shaping is completed, the release cylinder 531 drives the two moving plates 533 to move vertically under the guidance of the fourth guide rail 532, thereby driving the upper mold 534 and the lower mold 535 to move in opposite directions, so that the upper mold 534 and the lower mold 535 are separated from the shaped pipe, which facilitates the movement of the bent pipe;

[0076] After one pipe bending is completed, the reset cylinder 134 drives the first slide 133 to move rightward under the limiting action of the second guide rail 132, thereby driving the magnetic suspension sleeve 141 to move rightward through the first slide 133 and the pressing sleeve 135, and the magnetic suspension sleeve 141 drives the core rod 142 to move rightward, thereby driving the support spring 144 to move rightward through the connecting steel bar 143, so that the support spring 144 located at the bending position moves rightward to the position to be bent; repeat this operation until the bending is completed; then move the support spring 144 to the position to be bent, and clamp the pipe to be bent through the upper guide sleeve 435 and the lower guide sleeve 433, and start the cutting cylinder 61 to drive the cutter 62 to cut the bent pipe.
