[0026] Please refer to Figures 1 to 4 , and now a cooling mechanism for a wire drawing device provided by the present utility model will be described. A cooling mechanism for a wire drawing device includes a cooling tank 1, a ventilation and exhaust assembly 2, an oil injection ring 3, an oil collecting sleeve seat 4, and an oil storage tank 5. A lower concave oil collecting cavity 11 for accommodating cooling oil is provided at the bottom of the cooling tank 1. The ventilation and exhaust assembly 2 is connected to the top of the cooling tank 1 and is used to supply cold air into the cooling tank 1. An inlet guide wheel 12, a sinking guide wheel 13, and an outlet guide wheel 14 for guiding the metal wire 6 are rotatably connected in the cooling tank 1. The sinking guide wheel 13 is located in the oil collecting cavity 11 and is used to guide the metal wire 6 to immerse in the cooling oil. The oil injection ring 3 is disposed in the cooling tank 1 and is used to spray cooling oil onto the outer periphery of the metal wire 6. The oil collecting sleeve seat 4 is disposed in the cooling tank 1, and an oil blocking hole 41 for the metal wire 6 to pass through and for removing the cooling oil on the outer periphery of the metal wire 6 is provided on the oil collecting sleeve seat 4.
[0027] A cooling mechanism for wire drawing equipment provided in this embodiment, compared with the prior art, utilizes the air supply and exhaust assembly 2 disposed above the cooling box 1 to cool the metal wire 6 inside the cooling box 1 by air cooling. The oil liquid in the oil storage tank 5 is sent to the oil injection ring 3 to achieve liquid cooling and temperature reduction on the surface of the metal wire 6. The oil collecting cavity 11 is used to collect the oil liquid. The sinking guide wheel 13 guides the metal wire 6 into the oil liquid for further temperature reduction, and then the oil liquid on the surface of the metal wire 6 is removed by the oil collecting sleeve seat 4 provided with oil blocking holes 41. The air supply and exhaust assembly 2 further volatilizes the oil liquid on the surface of the metal wire 6. The above structure can effectively cool the metal wire 6, ensuring the forming quality of the product. By connecting the oil collecting cavity 11 and the oil storage tank 5, the reuse of the oil liquid is realized, reducing the operation cost of the equipment.
[0028] In a possible implementation manner, please refer to Figures 1 to 4 , the air supply and exhaust assembly 2 includes an air supply fan 21 and an exhaust fan 22. The air supply fan 21 is connected to the top of the cooling box 1 and is arranged corresponding to the outlet guide wheel 14 up and down. The air supply fan 21 is used to blow cold air into the cooling box 1 to cool the metal wire 6. The exhaust fan 22 is connected to the top of the cooling box 1 and is arranged corresponding to the inlet guide wheel 12 up and down. The exhaust fan 22 is used to suck out the air flow inside the cooling box 1.
[0029] In this embodiment, the air supply and exhaust assembly 2 uses the air supply fan 21 to supply cold air into the cooling box 1, and uses the cold air to take away the heat on the surface of the metal wire 6. The exhaust fan 22 then extracts the gas with a certain temperature inside the cooling box 1 to achieve the balance of the internal air pressure of the cooling box 1. Under the action of the air supply fan 21 and the exhaust fan 22, the low-temperature air flow forms an effective temperature reduction effect on the surface of the metal wire 6.
[0030] Specifically, the exhaust fan 22 is located above the inlet guide wheel 12, and the air supply fan 21 is located above the outlet guide wheel 14. The air flow first cools the metal wire 6 near the outlet side of the cooling box 1, ensuring that the metal wire 6 about to be sent out of the cooling box 1 is fully cooled. Then, the gas with a certain temperature flows towards the inlet side of the cooling box 1 to achieve the preliminary temperature reduction of the relatively hot metal wire 6 just entering the cooling box 1.
[0031] In some embodiments, please refer to Figures 1 to 4 , the top of the air supply fan 21 is connected with a cooling unit 23 and a filtering unit 24. The cooling unit 23 is located between the filtering unit 24 and the air supply fan 21. The cooling unit 23 is used to cool the external air flow to form cold air. The filtering unit 24 provided on the top of the cooling box 1 can effectively filter the external gas. Then, the cooling unit 23 cools the air flow to form cold air with a lower temperature and sends it into the cooling box 1. By blowing the cold air onto the surface of the metal wire 6, an air cooling effect is formed, which has a good temperature reduction effect on the metal wire 6.
[0032] In a possible implementation, refer to Figures 1 to 4 , the oil injection ring 3 is located between the inlet guide wheel 12 and the sinking guide wheel 13, the oil collecting sleeve seat 4 is located between the sinking guide wheel 13 and the outlet guide wheel 14, and a cooling heat exchange plate 51 is provided in the oil storage tank 5. The oil injection ring 3 is located between the inlet guide wheel 12 and the sinking guide wheel 13, and can spray oil to cool the wire 6 that has just entered the cooling tank 1. Then, the sinking guide wheel 13 guides the wire 6 into the oil collecting cavity 11, and the wire 6 is comprehensively cooled by the cooling oil. The oil collecting sleeve seat 4 is located between the sinking guide wheel 13 and the outlet guide wheel 14. After the wire 6 moves out of the oil collecting cavity 11, the oil collecting sleeve seat 4 uses the oil blocking holes 41 to clean the cooling oil on the surface of the wire 6, ensuring the cleanliness of the surface of the wire 6.
[0033] In this embodiment, the cooling heat exchange plate 51 in the oil storage tank 5 can cool down the oil liquid inside it, so that the cooling oil is cooled and flows back into the oil injection ring 3 for liquid cooling of the subsequent wire 6.
[0034] Specifically, the cooling heat exchange plate 51 is provided with a heat exchange tube extending in a serpentine shape. Both ends of the heat exchange tube extend outside the cooling tank 1. One end of the heat exchange tube is connected to the cooling water, and the other end is connected to the drain pipe. The cooling heat exchange plate 51 can effectively cool down the cooling oil.
[0035] In some embodiments, refer to Figures 1 to 4 , the oil blocking hole 41 is a tapered hole. The oil blocking hole 41 has a small diameter end 42 arranged close to the outlet guide wheel 14 and a large diameter end 43 arranged close to the sinking guide wheel 13. The large diameter end 43 of the oil blocking hole 41 is arranged on the side close to the sinking guide wheel 13, and the small diameter end 42 is arranged on the side close to the outlet guide wheel 14. The wire 6 moves from the large diameter end 43 to the small diameter end 42 of the oil blocking hole 41, gradually cleaning the cooling oil on the surface of the wire 6, so that the cooling oil flows down along the wire 6 into the oil storage cavity.
[0036] In some embodiments, refer to Figures 1 to 4 , two oil collecting sleeve seats 4 are provided between the sinking guide wheel 13 and the outlet guide wheel 14. The two oil collecting sleeve seats 4 are arranged at intervals along the direction of the wire 6. Two oil collecting sleeve seats 4 are provided, and the two oil collecting sleeve seats 4 are sleeved on different positions of the wire 6, and can process the cooling oil on the surface of the wire 6 twice, fully cleaning the cooling oil on the surface of the wire 6.
[0037] In a possible implementation, refer to Figures 1 to 4 , a diversion seat 7 is further provided in the cooling tank 1 between the air supply fan 21 and the exhaust fan 22. The diversion seat 7 extends along the axial direction of the sinking guide wheel 13, and the longitudinal section of the diversion seat 7 is a cone with a larger upper part and a smaller lower part.
[0038] In this embodiment, the diversion base 7 is provided to guide the cold air entering the cooling box 1, so that it fully contacts the metal wire 6, realizing effective cooling of the metal wire 6. The diversion base 7 is a conical structure with a larger upper part and a smaller lower part. The air flow sent by the air supply fan 21 flows from the diversion base 7 to the outlet side and then to the inlet side of the cooling box 1, achieving full contact with the metal wire 6, ensuring that the metal wire 6 about to be sent into the cooling box 1 contacts the air flow with the lowest temperature, and enabling the metal wire 6 to achieve the optimal cooling effect.
[0039] In a possible implementation manner, please refer to Figures 1 to 4 , an oil injection nozzle 31 inclined downward toward the axis is provided on the inner circumference of the oil injection ring 3. A limiting ring 32 for the metal wire 6 to pass through is provided in the middle of the oil injection ring 3. A connecting rod 33 extending radially and connected to the oil injection ring 3 is provided on the outer circumference of the limiting ring 32.
[0040] In this embodiment, the oil injection nozzle 31 provided inside the oil injection ring 3 can spray the cooling oil onto the outer peripheral wall of the metal wire 6. The limiting ring 32 inside the oil injection ring 3 can guide and limit the metal wire 6, so that the metal wire 6 is stably located at the axis position of the oil injection ring 3, and then the outer peripheral wall of the metal wire 6 is uniformly cooled through the oil injection nozzle 31.
[0041] In some embodiments, please refer to Figures 1 to 4 , a filter screen 15 is provided in the oil collecting chamber 11. A plurality of filter screens 15 are provided at intervals in the up and down directions. The storage tank 5 is communicated with the bottom of the oil collecting chamber 11. The filter screen 15 in the oil collecting chamber 11 can fully filter the cooling oil that has contacted the metal wire 6 material, ensuring the purity of the cooling oil. A liquid pump 53 is provided between the storage tank 5 and the cooling box 1. Under the action of the liquid pump 53, the cooling oil is sent from the oil collecting chamber 11 to the storage tank 5, realizing full reuse of the cooling oil. A flow valve 52 is also provided between the storage tank 5 and the oil injection ring 3, facilitating control of the flow rate of the cooling oil and convenient for control and adjustment.
[0042] In a possible implementation manner, please refer to Figures 1 to 4 , an inlet wheel set 16 and an outlet wheel set 17 are respectively provided inside the cooling box 1. An oil filtering ring 18 adjacent to the outlet wheel set 17 is provided on the inner side wall of the cooling box 1. A flexible oil absorbing pad 19 is provided on the inner circumference of the oil filtering ring 18. The inlet wheel set 16 and the outlet wheel set 17 provided inside the cooling box 1 can effectively traction the metal wire 6, so that the metal wire 6 moves orderly from the inlet side to the outlet side of the cooling box 1. The flexible oil absorbing pad 19 on the inner peripheral wall of the oil filtering ring 18 can adsorb a small amount of residual cooling oil on the surface of the metal wire 6, ensuring the cleanliness of the outer wall of the metal wire 6.
[0043] The above cooling mechanism for a wire drawing device can air-cool the wire 6 inside the cooling box 1 by arranging an air supply and exhaust component 2 above the cooling box 1. The oil liquid in the oil storage tank 5 is sent to the oil injection ring 3 to achieve liquid cooling and temperature reduction of the surface of the wire 6. The oil collecting cavity 11 is used to collect the oil liquid. The sinking guide wheel 13 guides the wire 6 into the oil liquid for further temperature reduction, and then the oil liquid on the surface of the wire 6 is removed by using the oil collecting sleeve seat 4 provided with oil blocking holes 41. The air supply and exhaust component 2 further volatilizes the oil liquid on the surface of the wire 6. The above structure can effectively cool the wire 6, ensure the forming quality of the product, realize the recycling of the oil liquid by connecting the oil collecting cavity 11 and the oil storage tank 5, and reduce the operation cost of the equipment.
