A positioning mechanism 8 is arranged on the fixed seat 2, and a punching mechanism 9 is arranged on the bracket 6.

[0022] Please refer to Figure 1 , Figure 2 , Figure 3, the positioning mechanism 8 includes a driving motor 81. The bottom of the inner wall of the fixed seat 2 is fixedly connected with the driving motor 81. The upper end of the output end of the driving motor 81 is fixedly connected with a screw rod 82. A screw sleeve 83 is threadedly connected to the outside of the screw rod 82. The top of the screw sleeve 83 is fixedly connected with a connecting frame 84. A pressing wheel 85 is hinged inside the connecting frame 84. A connecting bar 86 is fixedly connected to the outside of the screw sleeve 83. A guide rod 87 is slidably sleeved inside the connecting bar 86. The guide rod 87 is fixedly connected with the fixed seat 2. By designing the guide rod 87, the movement of the connecting bar 86 can be guided. The outside of the pressing wheel 85 contacts with a pulley 88. The number of pulleys 88 is two. The two pulleys 88 are symmetrically distributed on the outside of the pressing wheel 85. By designing the pulley 88, the pulley 88 will deflect when being extruded. The outside of the pulley 88 is hinged with a connecting rod 89. The connecting rod 89 is fixedly connected with the hinge rod 3. By designing the positioning mechanism 8, it is convenient to accurately position the pipeline 5.

[0023] Please refer to Figure 1 , Figure 2 , Figure 4 , the punching mechanism 9 includes a rotating motor 91. The top of the bracket 6 is fixedly connected with the rotating motor 91. The output end of the rotating motor 91 is rotatably connected with the bracket 6. The lower end of the output end of the rotating motor 91 is fixedly connected with a square rod 92. A connecting sleeve 93 is slidably sleeved on the outside of the square rod 92. A square groove 94 is opened inside the connecting sleeve 93. The square rod 92 is slidably sleeved inside the square groove 94.

[0024] The specific implementation process of the present utility model is as follows: When in use, first place the pipeline 5 inside the fixed seat 2, and then start the driving motor 81. The output end of the driving motor 81 drives the screw rod 82 to rotate, so that the screw sleeve 83 makes a threaded movement. The screw sleeve 83 drives the connecting bar 86 to slide along the guide rod 87. At the same time, the screw sleeve 83 drives the connecting frame 84 and the pressing wheel 85 to move downward. The pressing wheel 85 presses down the pulley 88. The pulley 88 drives the connecting rod 89 and the hinge rod 3 to deflect. The hinge rod 3 drives the clamping block 4 to deflect so that the clamping block 4 contacts with the pipeline 5, and then the pipeline 5 can be clamped and positioned. Since the two clamping blocks 4 deflect synchronously, the centering clamping of the pipeline 5 can be realized, so that the pipeline 5 can be aligned with the hot punch 96, thus avoiding the inaccurate positioning from affecting the punching effect.

[0025] After positioning is completed, the output end of the hydraulic cylinder 7 drives the pressing block 10 and the pressing rod 98 to move downward. The pressing rod 98 drives the support ring 97 and the connecting sleeve 93 to move downward. The connecting sleeve 93 slides along the square rod 92, causing the hot punch 96 to move downward. At the same time, the output end of the rotating motor 91 drives the square rod 92 to rotate, thereby enabling the connecting sleeve 93 and the hot punch 96 to rotate. The hot punch 96 can rotate and press downward into the interior of the pipe 5. When the hot punch 96 contacts the pipe 5, the pipe 5 can be heated and flared. While flaring, the hot punch 96 can also rotate, enabling the hot punch 96 to enter the interior of the pipe 5 more smoothly and improving the flaring efficiency.
