The bottom of the spray pipe 6 is provided with a liquid spraying port 61. The bottom of the oil receiving box 4 is connected to a liquid supply box 3. The liquid supply box 3 has a feeding channel 31 and a discharging channel 32 respectively opened on both sides. The ends of the feeding channel 31 and the discharging channel 32 are respectively connected to a liquid inlet connector 34 and a liquid outlet connector 35.

[0024] It also includes a U-shaped piston sleeve 36 disposed at the tail end of the liquid supply box 3, with the two ends of the U-shaped piston sleeve 36 respectively inserted into the feed channel 31 and the discharge channel 32.

[0025] During use, a cooling mechanism is provided for the lubricating and cooling oil of the thread rolling machine through the liquid supply box 3, oil receiving box 4, spray pipe 6, and U-shaped piston sleeve 36. This integrates cooling, filtration, and pumping, realizing the circulation supply and recovery of coolant, significantly improving cooling efficiency, reducing the accumulation of heat on the thread rolling template during processing, thereby protecting the machine from overheating damage and extending its service life.

[0026] The inlet connector 34 is equipped with a first check valve 37, the U-shaped piston sleeve 36 is provided with a second check valve 38 at one end of the feed channel 31, and the outlet connector 35 is equipped with a third check valve 39.

[0027] To remove foreign matter retained in the lubricating oil, for example, such as Figures 1-3 As shown, the present invention also includes a filter sleeve 310 mounted on the end of the U-shaped piston sleeve 36 away from the liquid supply box 3 via a flange, a metal filter screen 311 connected to one end of the filter sleeve 310, and a rejection end cap 312 threadedly connected to the bottom of the filter sleeve 310.

[0028] During use, foreign matter remaining in the filter sleeve 310 is discharged to the outside by unscrewing the discharge end cap 312.

[0029] To aid in cooling, for example, such as Figures 2-3 As shown, the present invention also includes an airflow channel 313 in the middle of the liquid supply box 3, a fan 314 with the same airflow direction installed at both ends of the airflow channel 313, a heat dissipation fin 315 horizontally arranged inside the airflow channel 313, and the heat dissipation fin 315 being welded to the liquid supply box 3 on both sides.

[0030] During use, the fan 314 operates, allowing air to quickly pass through the heat dissipation fins 315 in the airflow channel 313 inside the liquid supply box 3, thereby cooling the liquid supply box 3 and thus achieving auxiliary cooling of the lubricating oil.
