The fixed block 25 leaves the above-mentioned slide groove 28 for a movement cycle. During this cycle, the circular plate 52 is driven to rotate, so that the pipe that has been flanging is rotated, and the new unprocessed pipe moves to the position corresponding to the heating block 69 and the flanging block 68, and the processed pipe can be replaced by the new unprocessed pipe by the staff. This process is repeated to achieve the purpose of quickly replacing the pipe. The operation is simple, and the flanging efficiency of the pipe is significantly improved.

During the downward movement of the annular plate 39, the lifting plate 43 and the piston plate 42 are driven downward, and the external air is sucked into the cooling box 41 through the air inlet pipe 44. During the upward movement of the annular plate 39, the piston plate 42 is driven upward, and the air is pushed out of the cooling box 41 through the air outlet pipe 45. After the air enters the folding pipe 48 through the air outlet pipe 45, it flows through the folding pipe 48 and enters the air collecting box 49. At the same time, the solenoid valve 411 corresponding to the processed pipe is started, and the air is ejected through the cooling pipe 410, thereby achieving the purpose of cooling the processed pipe, so that the cooling rate of the pipe can be improved to avoid scalding the staff.
