The limiting mechanism 200 is installed beside the fin loading position 110 and has a first limiting plane 211, and the first limiting plane 211 is used for limiting the fin 10 located at the fin loading position 110. Therefore, when the worker places the fin 10 at the fin loading position 110, the first limiting plane 211 abuts against the fin 10, so as to limit one side of the fin 10, and the fin 10 is accurately positioned at the fin loading position 110. The tube threading device comprises a tube pushing mechanism 310 and a tube threading platform 320 which are both mounted on the frame 100. The first transfer mechanism 400 is attached to the rack 100 and has a position-restricting clamp groove 421 for clamping the tubular 20. The first transfer mechanism 400 grips the pipe 20 through the position-limiting clamp groove 421, and simultaneously limits the pipe 20 in the position-limiting clamp groove 421, so as to accurately position the position of the pipe 20. The first transfer mechanism 400 is used for moving the pipe 20 located at the pipe loading position 120 to the pipe pushing mechanism 310, so as to automatically load the pipe 20.

The heat exchanger pipe penetrating machine provided by the invention realizes automatic feeding and automatic blanking through the first transfer mechanism 400 and the second transfer mechanism 500, and the pipe penetrating device does not need to be stopped, so that the pipe penetrating device can continuously penetrate pipes.

In some embodiments, referring to fig. 2 and 4, the limiting mechanism 200 includes a material blocking member 210 installed on the frame 100, the material blocking member 210 is located at the end of the incoming direction of the fin 10, and the material blocking member 210 has a first limiting plane 211. The X direction in fig. 2 is the incoming direction of the fin 10. The fin 10 can be manually placed on the fin loading position 110, and the fin 10 is pushed to abut against the first limiting plane 211, so that positioning is realized.

Specifically, referring to fig. 4, the first limiting plane 211 of the material blocking member 210 has an avoiding hole 212, and the avoiding hole 212 can accommodate the pipe 20, so that when the fin 10 is positioned on the fin loading position 110, a small amount of pipe 20 which is pre-penetrated can enter the avoiding hole 212, and it is ensured that the first limiting plane 211 can directly abut against the fin 10 to limit the fin 10, rather than the first limiting plane 211 abutting against the small amount of pipe 20 which is pre-penetrated and protrudes out of the fin 10.

Specifically, referring to fig. 4, the limiting mechanism 200 further includes a material blocking driving member 220 installed on the frame 100, the material blocking driving member 220 is connected to the material blocking member 210, and is used for driving the material blocking member 210 to translate along the material feeding direction of the fins 10, so as to adjust the specific position of the first limiting plane 211, so as to position the fins 10 at different positions, and further meet the processing and positioning requirements of the fins 10 of different specifications.

The Y direction shown in fig. 2 is the machine direction. The pushing member 230 pushes the fin 10 to move from the first station 111 to the second station 112, and the fin 10 is grabbed and placed on the tube penetrating platform 320 by the second transferring mechanism 500 at the second station 112.

Thus, the tube pushing fixture 311 clamps and drives the tube 20 to move toward the tube penetrating platform 320, so that the tube 20 penetrates the fin 10 on the tube penetrating platform 320, and the tube penetrating operation is completed.

Specifically, the tube penetrating device further comprises a tube penetrating guide rail 330 mounted on the frame 100, and the tube pushing clamp 311 is slidably mounted on the tube penetrating guide rail 330.
