[0033] 4. Heating and flanging:

[0034] (1) Place the pipe on the supporting heating structure of the heating transformer by means of a truss manipulator;

[0035] (2) The heating cylinder starts to pull the second support platform, so that the heaters at both ends press and heat the two ends of the pipe. The two ends of the pipe are heated and the heating cylinder continues to squeeze until the two ends of the pipe are flared;

[0036] (3) After the set time is reached, the heating cylinder pushes away from the second support platform, and the heaters at both ends are separated from the pipeline;

[0037] 4. Cooling and shaping:

[0038] (1) The pipe is transferred from the heating and deforming machine to the supporting shaping structure of the shaping and cooling machine by a truss manipulator;

[0039] (2) The end face pressing cylinder is started to press the two end faces of the pipe with the fixed flanges at both ends;

[0040] (3) Water is poured into the water tank through the water inlet, and the water covers the pipes for cooling. After cooling and shaping for a set time, the water is discharged from the water outlet;

[0041] (4) The end face pressing cylinder returns to the origin, the forming flange is separated from the two end faces of the pipe, and the truss manipulator transfers the pipe from the forming cooling machine to the finished product area. The pipe in the finished product area is finally placed in the pipe drying oven for drying.

[0042] Among them, in step 4 and step 5, the specific steps of the truss manipulator moving the pipeline are as follows:

[0049] First, manually adjust the heating and forming machine and the shaping and cooling machine according to the size and length of the pipeline, so that the center of the heater or the shaping flange is aligned with the center of the pipeline, which is convenient for the subsequent fully automatic heating and flanging and cooling and shaping. During heating and flanging, the heater is continuously heated and pressed on both ends of the pipeline through the heating cylinder, and the heating and flanging of both ends of the pipeline can be achieved in one process, which improves work efficiency.

Direct cooling after automatic shaping is adopted, and there is no need for manual assembly and fastening of flanges. Truss manipulators are used to automatically transfer workpieces between all processes, which is highly efficient and requires less manual work. The specific beneficial effects are as follows:

[0052] 1. Adjust the position of the first support platform on the first track according to the length of the pipeline so that the heaters at both ends are close to the pipeline. After determining the position of the heater, fix the slider to the first track with bolts. The first track and the first support platform are set to adjust the position of the heater. When heating and flanging, the two ends of the pipeline soften and the length of the pipeline becomes shorter. Therefore, the second support platform is pulled by the heating cylinder so that the heating structures at both ends continuously press the two ends of the pipeline, and the flanging effect of both ends of the pipeline is achieved in one process.

[0053] 2. According to the different sizes of pipelines, the positioning plate of the center positioning adjustment seat is driven by the motor screw to move up and down, and the center of the heater or positioning flange is aligned with the center of the pipeline.

[0054] 3. Adjust the position of the third support platform on the third track according to the length of the pipeline, so that the shaping structures at both ends are close to the pipeline. After determining the position of the heater, fix the slider on the third track with bolts. The third track and the third support platform are set to adjust the position of the shaping structure. The end face clamping cylinder makes the shaping flanges at both ends continuously press the two ends of the pipeline, and the compression effect of both ends of the pipeline is achieved in one process. The shaped pipeline is cooled in the water tank, the cooling time is short, and the efficiency is greatly improved.

[0055] 4. The rotation of the x-axis motor drives the x-axis conveyor belt to rotate, and drives one of the x-axis sliders to slide on the x-axis track, thereby moving the position of the pipe fixture in the x-axis direction. Similarly, the rotation of the y-axis motor drives the y-axis conveyor belt to rotate, and drives the y-axis slider to slide on the y-axis track, thereby moving the position of the pipe fixture in the y-axis direction. Thus, the pipe fixture can be moved to the specified position on the xy plane. The rotation of the z-axis motor drives the gear to rotate, and the gear and the rack on the z-axis of the truss cooperate to enable the z-axis of the truss to drive the pipe fixture up and down. The cooperation of the z-axis track and the z-axis slider improves the stability of the z-axis of the truss. BRIEF DESCRIPTION OF THE DRAWINGS

3. A flanging shaping method using the heating flanging shaping device as claimed in claim 1 or 2, characterized in that:

1. Heating deformation machine position debugging: (1) Place the pipe on the supporting heating structure of the heating transformer; (2) Adjust the position of the center positioning adjustment seat to align the center of the heater with the center of the pipe; (3) moving the first support platform on the first track according to the length of the pipeline so that both ends of the pipeline are close to the heater, and fixing the position of the first slider by bolts to fix the first support platform; 2. Position debugging of the shaping cooling machine: (1) Place the pipe on the supporting structure of the shaping cooler; (2) Adjust the position of the center positioning adjustment seat to align the center of the fixed flange with the center of the pipeline; (3) Move the third support platform on the third track according to the length of the pipeline so that both ends of the pipeline are close to the fixed flange, and fix the position of the third slider by bolts to fix the third support platform; 3. Heating and flanging: (1) Place the pipe on the supporting heating structure of the heating transformer by using the truss manipulator; (2) The heating cylinder starts to pull the second support platform, so that the heaters at both ends press and heat the two ends of the pipe. The heating cylinder continuously squeezes the two ends of the pipe while heating them until the two ends of the pipe are flared; (3) When the set time is reached, the heating cylinder pushes away from the second support platform, and the heaters at both ends are separated from the pipeline; 4. Cooling and shaping: (1) The pipe is transferred from the heating and deforming machine to the supporting shaping structure of the shaping and cooling machine through the truss manipulator; (2) The end face pressing cylinder is started to press the two end faces of the pipe with the fixed flanges at both ends; (3) Water is poured into the water tank through the water inlet, and the water covers the pipe for cooling. After cooling and shaping for a set time, the water is discharged from the water outlet; (4) The end face pressing cylinder returns to the origin, the forming flange is separated from the two end faces of the pipe, and the truss manipulator transfers the pipe from the forming cooling machine to the finished product area. The pipe in the finished product area is finally placed in the pipe drying oven for drying; Among them, in step 3 and step 4, the specific steps of the truss manipulator moving the pipeline are as follows: (1) The pipe clamp moves to the specified position along the x-axis and y-axis driven by the x-axis moving component and the y-axis moving component; (2) The rotation of the z-axis motor drives the gear to rotate. The gear cooperates with the rack of the truss z-axis to move the truss z-axis downward, so that the pipe clamp moves near the pipe; (3) The double cylinder is started to clamp the pipe; (4) The z-axis motor rotates in the opposite direction to move the pipe clamp upward and moves to the next designated position through the x-axis moving component; (5) The z-axis motor rotates to move the pipe clamp downward. After the movement stops, the double-cylinder cylinder returns to its original position to release the clamp and place the pipe in the specified position; (6) The z-axis motor rotates in the opposite direction to move the pipe clamp upward, and steps (1) to (5) are repeated until all pipes are moved.
