[0027] like Figures 1 to 5 As shown, this utility model provides a multi-station cold heading machine for forming drill tail wire, including: a main structure 1, which includes a cold heading machine body 11, a filter screen 12 and a drain tank 13; The filter structure 2 includes an inlet pipe 21, a filter cylinder 22, a ball valve 23, an outlet pipe 24, a filter screen cylinder 25, a drive motor 26, and a cleaning brush 28. The inlet pipe 21 is fixedly connected to the inside of one side surface of the cold heading machine body 11, and the inside of the inlet pipe 21 is connected to the inside of the drain tank 13. The circulating cooling structure 3 includes a coolant circulating pump 31, a first connecting pipe 32, a liquid storage tank 34, a fixing plate 36, a diversion pipe 37, and a spray pipe 38. The spray pipe 38 is provided in multiple sets. The coolant circulating pump 31 is installed on the outer surface of one side of the cold heading machine body 11. The lower end of the first connecting pipe 32 is connected to the inside of the liquid outlet pipe 24.

[0028] The filter screen 12 is fixedly connected to the surfaces of both sides inside the cold heading machine body 11, and the drain trough 13 is opened inside the cold heading machine body 11, with the filter screen 12 located at the upper end of the drain trough 13.

[0029] The cold heading machine body 11 can perform cold heading of the drill tail wire, and the filter screen 12 can perform preliminary filtration of the coolant after use. The filtered coolant will flow into the interior of the drain tank 13 through the filter screen 12. The filtration of the filter screen 12 can prevent large particles of debris from entering the interior of the drain tank 13.

[0030] The cold heading machine body 11 has a discharge port 14 inside one side surface, and a discharge plate 15 is fixedly connected to the outer surface of one side surface of the cold heading machine body 11, with the position of the discharge plate 15 corresponding to the position of the discharge port 14.

[0031] After processing, the workpiece will move towards the discharge port 14 on the upper surface of the filter screen plate 12 by its own gravity, and finally be discharged outward through the discharge port 14 and the discharge plate 15.

[0032] The filter cylinder 22 is fixedly connected to one end of the inlet pipe 21, and the interior of the filter cylinder 22 is connected to the interior of the inlet pipe 21. The ball valve 23 is installed inside the lower end of the inlet pipe 21, and the outlet pipe 24 is connected to the interior of the filter cylinder 22.

[0033] The coolant inside the drain tank 13 can be introduced into the filter cylinder 22 through the inlet pipe 21. Impurities inside the coolant will settle downwards inside the filter cylinder 22 due to their own gravity and collect at the lower end of the filter cylinder 22. After opening the ball valve 23, the impurities at the lower end of the filter cylinder 22 can be discharged outwards.

[0034] The filter cylinder 25 is installed inside the filter cylinder 22, and the outer surface of the filter cylinder 25 is attached to the inner surface of the filter cylinder 22. A connecting port is opened on one side of the filter cylinder 25, and the position of the connecting port corresponds to the position inside the liquid inlet pipe 21.

[0035] The filter cylinder 25 can perform secondary filtration of the coolant, which can prevent impurities from flowing into the interior of the outlet pipe 24 with the coolant. The outer surface of the filter cylinder 25 and the inner surface of the filter cylinder 22 are sealed together by a rubber sealing ring to prevent the coolant from flowing out from the gap without filtration.

[0036] The drive motor 26 is mounted on the upper surface of the filter cartridge 22. A connecting shaft 27 is fixedly connected to the output shaft of the drive motor 26, and the upper end of the connecting shaft 27 is connected to the internal bearing on the upper surface of the filter cartridge 22. The cleaning brush 28 is fixedly connected to the outer surface of the connecting shaft 27.

[0037] By starting the drive motor 26, the connecting shaft 27 and the cleaning brush 28 can be rotated. The connection between the connecting shaft 27 and the bearing inside the upper surface of the filter cartridge 22 can effectively improve the stability of the connecting shaft 27 and the cleaning brush 28 during rotation.

[0038] The cleaning brush 28 has bristles on the surface near the filter cylinder 25, and the bristles are attached to the inner surface of the filter cylinder 25.

[0039] The rotation of the cleaning brush 28 allows the bristles to clean the inside of the filter cylinder 25, effectively reducing the likelihood of clogging.

[0040] The upper end of the first connecting pipe 32 is connected to the interior of one side surface of the coolant circulation pump 31, and the interior of the upper surface of the coolant circulation pump 31 is connected to the second connecting pipe 33, and the upper end of the second connecting pipe 33 is connected to the interior of the liquid storage tank 34.

[0041] After the coolant circulation pump 31 is started, the coolant filtered inside the filter cartridge 22 can be drawn into the coolant circulation pump 31 through the first connecting pipe 32. After entering the coolant circulation pump 31, the coolant exchanges heat with the external cold air through the air-cooled fins inside the coolant circulation pump 31, reducing the coolant temperature from 60-70℃ after processing to 25-30℃, and then flows back to the inside of the storage tank 34 through the second connecting pipe 33.

[0042] The liquid storage tank 34 is fixedly connected to one side of the upper surface of the cold heading machine body 11. The liquid inlet 35 is fixedly connected to the inside of the upper surface of the liquid storage tank 34, and the inside of the liquid inlet 35 is connected to the inside of the liquid storage tank 34. A liquid pump is installed inside the liquid storage tank 34.

[0043] The inlet 35 allows operators to easily add coolant to the reservoir 34, and the upper surface of the inlet 35 is equipped with a sealing cap to prevent external dust and impurities from entering the reservoir 34.

[0044] The fixed plate 36 is fixedly connected to the surface of one side inside the cold heading machine body 11. The two ends of the diversion pipe 37 are fixedly connected to the inner surface of the fixed plate 36. The inside of the diversion pipe 37 is connected to the liquid pump inside the liquid storage tank 34. Multiple sets of spray pipes 38 are respectively connected to the inside of the diversion pipe 37.

[0045] The coolant inside the storage tank 34 is pumped by a pump to the inside of the distribution pipe 37, and then sprayed out through multiple sets of spray pipes 38 to cool the workpiece.

[0046] The working principle and usage process of this utility model are as follows: During use, the main body 11 of the cold heading machine performs cold heading of the drill tail wire. During processing, the pump inside the liquid storage tank 34 delivers the coolant to the distribution pipe 37, and then sprays it out through multiple sets of spray pipes 38 to cool the processing mechanism and the workpiece. After use, the coolant is first filtered by the filter screen plate 12 and then enters the drain tank 13. It then flows into the filter cylinder 22 of the filter structure 2 through the inlet pipe 21 and is filtered a second time by the filter screen cylinder 25. The filtered coolant enters the coolant circulation pump 31 for cooling through the outlet pipe 24 and the first connecting pipe 32. Finally, it flows back to the liquid storage tank 34 through the second connecting pipe 33 to achieve recycling. At the same time, the drive motor 26 can be started to drive the connecting shaft 27 and the cleaning brush 28 to rotate, cleaning the inner surface of the filter screen cylinder 25 to prevent clogging. The impurities deposited in the filter cylinder 22 can be discharged by opening the ball valve 23.

[0047] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
