A fixed sleeve 42 for fixing the composite finned tube is slidably connected to the upper end of the fixed seat 4. A rotating base 5 is rotatably connected to the inner side of the installation seat 2. An adapter groove 51 is opened at the front end of the rotating base 5. A loading mold 6 is fixed to the adapter groove 51 by fixing bolts. The loading mold 6 has a ring structure and a grinding ring 61 is fixed to the inner side. A drive assembly for driving the rotating base 5 to rotate is provided at the upper end of the installation seat 2. A hydraulic cylinder 32 is fixed on the equipment frame 3, and a top plate 31 is fixed to the output end of the hydraulic cylinder 32.

[0019] The drive assembly includes a servo motor 21, a driven gear 52, and a gear belt 23. The servo motor 21 is fixed to the upper end of the mounting base 2, and a drive gear 22 is fixed to the output end of the servo motor 21. The driven gear 52 is fixed to the outside of the rotating base 5 and aligned with the drive gear 22. The gear belt 23 is installed between the drive gear 22 and the driven gear 52. A mounting groove 28 is provided on the mounting base 2 at a position corresponding to the rotating base 5. The outside of the mounting base 2, aligned with the mounting groove 28, is fixed by fixing bolts. There is a back plate 26, on which a guide post 27 is fixed. The end of the guide post 27 is located inside the loading mold 6, and its diameter is adapted to the inner diameter of the main pipe of the composite finned tube. The inner diameter of the grinding ring 61 is adapted to the outer diameter of the base tube of the composite finned tube. The inner diameter of the loading mold 6 is larger than the maximum diameter of the composite finned tube. When the composite finned tube is inserted into the loading mold 6, its guide post 27 will be inserted into the main pipe of the composite finned tube, which can achieve the purpose of guidance, increase the support strength of the end of the composite finned tube, and reduce the risk of vibration.

[0020] A cooling water pipe 24 is fixed on the mounting base 2, and a nozzle 25 is fixed at the end of the cooling water pipe 24. The nozzle 25 is aligned with the grinding ring 61.

When fixing the composite finned tube, the composite finned tube is first placed into the fixed sleeve 42, and then the cover 43 is snapped and fixed. Finally, the composite finned tube is fixed in the fixed sleeve 42 by locking the locking bolts 44. Secondly, when the hydraulic cylinder 32 pushes the end of the composite finned tube, the slide rail 41 is used to limit the movement of the composite finned tube to ensure that it can only move horizontally.

[0022] Working principle: First, connect the entire device to an external power source. Then, fix the composite finned tube into the fixed sleeve 42. Simultaneously, drive the drive gear 22 to rotate using the servo motor 21. Furthermore, drive the rotating base 5 and loading mold 6 to rotate using the driven gear 52 and gear belt 23. Finally, push the hydraulic cylinder 32 to insert the composite finned tube into the loading mold 6. At this time, the base tube of the composite finned tube will pass through the annular grinding disc, and the fins will be ground on the surface of the annular grinding disc to achieve the purpose of stripping the head. The overall operation is relatively simple and greatly improves work efficiency.
