Description

Technical Field

[0001] This invention relates to the field of wire drawing equipment technology, and in particular to a cooling device, equipment and process for drawing irregularly shaped copper wires. Background Technology

[0002] For large-section cables formed by stranding, multiple single copper wires with irregular (non-circular) cross-sections need to be stranded together. Common irregular copper wires are similar to triangular copper wires. The small ends of multiple copper wires are located on the inside, and the large ends are located on the outside. Finally, they are stranded together to form a large-section cable with a circular cross-section.

[0003] The irregularly shaped copper wire is also manufactured by drawing using a wire drawing machine. During the drawing process, the size of the copper wire gradually decreases, and some scratches and debris will be generated on the surface of the copper wire. Finally, steam cleaning is required to avoid oxidation of the wire surface and achieve a high degree of cleanliness of the wire surface.

[0004] Existing copper wire drawing cooling structures employ a single cooling pool. The steam-cleaned copper wire directly enters the bottom cooling pool and comes into contact with cooling water, achieving cooling while removing some residual metal debris from the surface. However, for irregularly shaped copper wires, the steam cleaning and cooling process can easily cause them to vibrate or sway within the cooling pipes, resulting in more residual debris on their surface. A single cooling structure cannot effectively remove this residual metal debris. Furthermore, the thickness of irregularly shaped wires differs between the center and edges, making it impossible to achieve gradient cooling with a single structure. If the cooling rate is too fast, the edges will shrink first, leading to thermal stress within the wire, causing distortion and affecting the quality of the finished product. Summary of the Invention

[0005] To address the aforementioned problems, this invention provides a cooling device, equipment, and process for drawing irregularly shaped copper wire. This invention can perform multi-stage gradient cooling to reduce the temperature of irregularly shaped copper wire after steam cleaning, ensuring the quality and relative smoothness of the surface of the irregularly shaped copper wire, and ensuring the normal and efficient operation of subsequent processing and winding.

[0006] To solve the above problems, the technical solution adopted by the present invention is as follows:

[0007] A cooling device for drawing irregularly shaped copper wire includes a cooling structure located below a steam cleaning device. The cooling structure contains a guide wheel assembly for the irregularly shaped copper wire to pass through. The cooling structure includes a first cooling filter body and a second cooling filter body. The first cooling filter body is located between the second cooling filter body and the steam cleaning device. The first cooling filter body includes a first cooling chamber and a first coolant circulation assembly. The second cooling filter body contains a second coolant circulation assembly, which includes a serpentine heat exchanger located inside the second cooling filter body and a circulation body located outside the second cooling filter body. The second cooling filter body also contains a coolant flushing assembly communicating with the circulation body. Both the first and second coolant circulation assemblies have built-in filter structures.

[0008] Preferably, the first cooling filter body further includes a settling protrusion located at the bottom of the first cooling chamber, the settling protrusion having a predetermined vertical height.

[0009] Preferably, the first coolant circulation assembly includes a circulation pipe, a portion of which extends to the outside of the first cooling chamber and is fitted with a first heat exchange structure, and a first filter assembly is disposed inside the circulation pipe.

[0010] Preferably, the first cooling filter body further includes a cleaning component located in the first cooling chamber. The cleaning component has an annular cleaning opening inside. The first end of the circulation pipe is connected to the bottom of the first cooling chamber, and the second end is connected to the cleaning opening.

[0011] Preferably, the cleaning component has a hollow interior with a tightening area, a first upward-opening guide area at the upper end of the tightening area, a second downward-opening guide area at the lower end, and a guide plate fixed to the outside of the first guide area.

[0012] Preferably, the serpentine heat exchanger includes a tubular cooling body, a serpentine heat exchange tube fixed to the outside of the cooling body, a liquid inlet connector at the first end of the serpentine heat exchange tube, and a liquid outlet connector at the second end.

[0013] Preferably, the circulation body includes an extraction pipe with a built-in second filter assembly. The first end of the extraction pipe is connected to the bottom of the second cooling filter body, and the second end is connected to the liquid inlet connector. The circulation body also includes a return pipe connected in series with a second heat exchange structure. The first end of the return pipe is connected to the liquid outlet connector, and the second end is connected to the coolant flushing assembly.

[0014] Preferably, an upwardly inclined drying device is also provided on the outside of the second cooling filter body, and the bottom edge of the guide wheel assembly is located below the bottom of the drying device.

[0015] A cooling device for drawing irregular copper wire includes the aforementioned cooling device for drawing irregular copper wire, and further includes a winding structure and an unwinding structure. A temperature detection component one is provided at the bottom of the first cooling filter body and electrically connected to it. A temperature detection component two is provided at the bottom of the serpentine heat exchange device and electrically connected to it. A temperature detection component three is provided on the side of the coolant flushing component near the guide wheel assembly. The temperature detection component three is electrically connected to the winding structure and the unwinding structure.

[0016] A cooling process for drawing irregularly shaped copper wire, using the aforementioned cooling equipment, includes the following steps: S1. When temperature detection component one detects a temperature exceeding a first set range, the cooling effect of the first cooling filter body is increased; when temperature detection component one detects a temperature below the first set range, the cooling effect of the first cooling filter body is decreased; S2. When temperature detection component two detects a temperature exceeding a second set range, the cooling effect of the serpentine heat exchanger is increased; when temperature detection component two detects a temperature below the second set range, the cooling effect of the serpentine heat exchanger is decreased; S3.

[0017] The beneficial effects of this invention are as follows:

[0018] Compared with existing technologies, the above structural design allows for the removal of residual debris and impurities from the surface of the shaped copper wire after steam cleaning. The wire then sequentially enters the first and second cooling filter bodies for multi-stage gradient cooling, ensuring stability during the cooling process. The cooling liquid circulation component not only achieves cooling but also allows for the targeted collection of metal impurities in the cooling liquid through the filtration structure. This minimizes residual metal debris and other impurities in the first and second cooling filter bodies, ensuring a relatively smooth surface for the shaped copper wire and facilitating efficient and normal subsequent processing and winding. Furthermore, it effectively guides and collects the distilled cooling liquid, preventing oxidation of the shaped copper wire surface and guaranteeing the quality of the final product.

Detailed Implementation

[0029] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0030] To address the problems mentioned in the background art, see Appendix Figure 1 - Appendix Figure 6A special-shaped copper wire drawing and cooling device includes a cooling structure located below a steam cleaning device 100. Inside the cooling structure is a guide wheel assembly 400 through which the special-shaped copper wire 700 passes. The drawn copper wire passes through the steam cleaning device 100 and the cooling structure in sequence, and finally passes around the guide wheel assembly 400 to be transported to the outside. After being cleaned by steam in the steam cleaning device 100, it undergoes gradient cooling in the cooling structure, and finally is dried and wound into a roll.

[0031] The steam cleaning device 100 described above forms a cleaning chamber 110 inside, and a cleaning base 120 and a cleaning sleeve 130 are provided inside the cleaning chamber 110. The cleaning sleeve 130 is connected to a steam pipe. By spraying high-temperature steam into the cleaning sleeve 130, the irregular copper wire 700 inside the cleaning sleeve 130 is cleaned by steam. The above is the prior art and will not be described in detail here.

[0032] Specifically, the cooling structure includes a first cooling filter body 200 and a second cooling filter body 500. The first cooling filter body 200 is located between the second cooling filter body 500 and the steam cleaning device 100. The first cooling filter body 200 and the second cooling filter body 500 can be located at different positions to perform gradient cooling on the shaped copper wire 700, controlling the shaped copper wire 700 to cool from a high temperature state to a room temperature state, so as to meet the needs of subsequent processing and winding.

[0033] The first cooling and filtering body 200 includes a first cooling chamber 220 and a first coolant circulation assembly 240. The first cooling chamber 220 can accommodate distilled water droplets flowing in from the steam cleaning device 100 above. At the same time, the first coolant circulation assembly 240 can control the directional circulation of distilled water in the first cooling chamber 220 to achieve cooling and filtration of the distilled water, reduce the temperature in the first cooling chamber 220, achieve one-stage cooling of the shaped copper wire 700, and achieve directional collection of metal debris in the first cooling chamber 220 to reduce impurities in the distilled water and prevent the shaped copper wire 700 from being squeezed and rubbed during subsequent cooling and winding.

[0034] The steam cleaning device 100, the first cooling filter body 200, and the second cooling filter body 500 are arranged vertically from top to bottom. During the process described above, the steam in the steam cleaning device 100 cools and forms droplets after encountering the cooler metal structure on the outside. The gradually increasing liquid flows downward along the channel through which the shaped copper wire 700 moves, forming distilled cooling water in the first cooling filter body 200 and the second cooling filter body 500, respectively. The distilled cooling water contains few impurities, which prevents the shaped copper wire 700 from being oxidized. At the same time, it can achieve efficient guidance and discharge and efficient utilization of the distilled cooling water.

[0035] It should be noted that the outer sides of the steam cleaning device 100, the first cooling filter body 200, and the second cooling filter body 500 are enclosed structures. In order to show the internal structure more clearly, this application has hidden the outer enclosed structure.

[0036] A second coolant circulation assembly is provided inside the second cooling filter body 500. The second coolant circulation assembly includes a serpentine heat exchange device 300 located inside the second cooling filter body 500 and a circulation body located outside the second cooling filter body 500. A coolant flushing assembly 530 connected to the circulation body is also provided inside the second cooling filter body 500. Through the above structural design, the temperature of the environment inside the second cooling filter body 500 can be reduced. The irregular copper wire 700 passes through the guide wheel assembly 400 and is located at the bottom of the second cooling filter body 500, directly contacting the distilled cooling water to achieve the second stage of cooling of the irregular copper wire 700. Finally, the irregular copper wire 700 passes through the coolant flushing assembly 530, and the coolant flushing assembly 530 sprays out a cooler cooling liquid to achieve the third stage of cooling of the irregular copper wire 700.

[0037] The cooling liquid in the second cooling filter body 500 is drawn into the serpentine heat exchanger 300 to cool and exchange heat with the environment around the serpentine heat exchanger 300. The cooling liquid discharged from the serpentine heat exchanger 300 can be further cooled by the external circulation body and finally sprayed out from the coolant flushing component 530 to achieve the final cooling and temperature reduction of the irregular copper wire 700, thus achieving gradient cooling.

[0038] Through the above structural design, the serpentine heat exchanger 300 can also perform non-contact cooling of the shaped copper wire 700. By reducing the ambient temperature, the temperature inside the serpentine heat exchanger 300 can be reduced, directly exchanging heat between the shaped copper wire 700 and the distilled cooling water flowing downwards within the serpentine heat exchanger 300. A refined cooling transition is achieved between the first and second stage cooling, enabling more precise and stable gradient cooling. This avoids excessively large temperature differences in the shaped copper wire 700, which could lead to an excessively fast cooling rate, thus ensuring the final quality of the shaped copper wire 700.

[0039] It should be noted that there is cooling liquid flowing downwards on the inner wall of the serpentine heat exchanger 300. When more cooling liquid enters from above, the volume of cooling liquid filling the serpentine heat exchanger 300 is larger. The irregular copper wire 700 is in a non-contact state with the inner wall of the serpentine heat exchanger 300, avoiding wear during contact. The above-mentioned cooling can directly cool the cooling liquid inside the serpentine heat exchanger 300 and indirectly cool the irregular copper wire 700 inside the serpentine heat exchanger 300.

[0040] Both the first coolant circulation assembly 240 and the second coolant circulation assembly have built-in filter structures. Both the first coolant circulation assembly 240 and the second coolant circulation assembly control the directional circulation flow of the corresponding distilled cooling water. Through the filter structure, metal debris can be intercepted and filtered in the directional circulation flow of distilled cooling water, thereby minimizing the amount of metal debris and other impurities remaining in the first cooling filter body 200 and the second cooling filter body 500, ensuring the relative smoothness of the surface of the shaped copper wire 700, and ensuring the normal progress of subsequent processing and winding.

[0041] In summary, through the above structural design, the irregularly shaped copper wire 700, after being steam-cleaned by the steam cleaning device 100, can remove residual debris and impurities from its surface. It then sequentially enters the first cooling filter body 200 and the second cooling filter body 500 for multi-stage gradient cooling, ensuring stability during the cooling process. The cooling liquid circulation component achieves cooling while simultaneously using the filtration structure to collect and concentrate metallic impurities in the cooling liquid, minimizing residual metal debris and other impurities in the first and second cooling filter bodies 200 and 500. This ensures a relatively smooth surface for the irregularly shaped copper wire 700, guaranteeing the smooth operation of subsequent processing and winding. Furthermore, it effectively guides and collects the distilled cooling liquid, preventing oxidation of the irregularly shaped copper wire 700 and ensuring the quality of the final product.

[0042] Specifically, the first cooling filter body 200 also includes a settling protrusion 230 located at the bottom of the first cooling chamber 220. The settling protrusion 230 has a predetermined vertical height. Through the above structural design, a certain interception height can be formed at the bottom of the first cooling chamber 220, which can accommodate and collect the distilled cooling water flowing in from the steam cleaning device 100. The distilled cooling water can be collected and settled within a certain interception height, and can also be drawn and collected by the first coolant circulation component 240 on the outside, thus minimizing the transfer of metal debris to the second cooling filter body 500. At the same time, the certain interception height can accommodate more cooling liquid. The increase in cooling liquid can reduce temperature fluctuations within the first cooling filter body 200, achieving more stable gradient cooling and ensuring product quality.

[0043] The settling protrusion 230 here includes an intercepting sleeve 231 and an adjusting element 232. The intercepting sleeve 231 is a lockable telescopic element. The height of the intercepting sleeve 231 can be adjusted by rotating the adjusting element 232. The overall height of the settling protrusion 230 can be adjusted according to the size of the irregular copper wire 700 and the needs of the production process, thereby adjusting the amount of cooling distilled water contained in the first cooling filter body 200 to meet the needs of different production processes.

[0044] Specifically, the first coolant circulation assembly 240 includes a circulation pipe 241, which has a built-in water pump to achieve unidirectional circulation of coolant. The circulation pipe 241 extends to the outside of the first cooling chamber 220 and is fitted with a first heat exchange structure 242. A first filter assembly 243 is installed inside the circulation pipe 241. The first heat exchange structure 242 can be selected as heat exchange fins with a certain heat exchange and cooling effect. The first filter assembly 243 is selected as a detachable filter assembly, which can be disassembled and replaced periodically to meet the requirements of continuous and efficient heat exchange and cooling effect.

[0045] The first cooling filter body 200 also includes a cleaning component 210 located in the first cooling chamber 220. The cleaning component 210 has an annular cleaning opening inside. The first end of the circulation pipe 241 is connected to the bottom of the first cooling chamber 220, and the second end is connected to the cleaning opening.

[0046] Through the above structural design, the cooling liquid containing metal debris and impurities at the bottom of the first cooling chamber 220 can be extracted through the circulation pipe 241, the metal debris can be filtered through the first filter assembly 243, and the cooling liquid can be cooled through the first heat exchange structure 242. Finally, the cooled liquid is sprayed out from the annular cleaning opening. The shaped copper wire 700 passes through the cleaning opening, and the sprayed cooling liquid can directly cool the shaped copper wire 700 for the first time. At the same time, it can also wash away the metal debris and impurities remaining on the surface of the shaped copper wire 700, reducing the amount of metal debris that subsequently enters the second cooling filter body 500.

[0047] A tightening area 212 is hollowly provided inside the cleaning component 210. A first guide area 213 that opens upward is provided at the upper end of the tightening area 212, and a second guide area 211 that opens downward is provided at the lower end. A guide plate 214 is fixed on the outside of the first guide area 213.

[0048] Within the tightening area 212, an elastic tightening ring can be fixed. The tightening ring is located below the aforementioned cleaning opening. Most of the liquid sprayed from the cleaning opening flows upward, opposite to the conveying direction of the shaped copper wire 700, achieving efficient scouring and cooling of the surface of the shaped copper wire 700. At the same time, it can discharge metal impurities upward, passing through the outer guide plate 214 and falling into the outer first cooling chamber 220, minimizing the downward movement of metal impurities along the moving path of the shaped copper wire 700. Simultaneously, a small portion of the cooling liquid flows downward along the second guide area 211. The cooling liquid flows outward at an angle along the bottom of the second guide area 211, guiding a small portion of the cooling liquid to flow outward, deviating from the moving path of the shaped copper wire 700, similarly minimizing the downward movement of metal impurities along the moving path of the shaped copper wire 700.

[0049] Specifically, the serpentine heat exchanger 300 includes a tubular cooling body 330, with a serpentine heat exchange tube 340 fixed to the outside of the cooling body 330. The serpentine heat exchange tube 340 has an inlet connector 310 at its first end and an outlet connector 320 at its second end. The cooling liquid in the second cooling filter body 500 has a relatively low temperature. By introducing the cooling liquid in the second cooling filter body 500 into the serpentine heat exchange tube 340 through the inlet connector 310 and discharging it from the outlet connector 320, the cooling liquid flows directionally within the serpentine heat exchange tube 340, thereby cooling the higher-temperature cooling liquid in the cooling body 330 and the shaped copper wire 700. This achieves gradient cooling and enables a cooling transition between the first cooling filter body 200 and the second cooling filter body 500, preventing the temperature drop rate from being too high and affecting the quality of the finished shaped copper wire 700.

[0050] Specifically, the circulation body includes an extraction pipe 510 with a built-in second filter assembly 511. The first end of the extraction pipe 510 is connected to the bottom of the second cooling filter body 500, and the second end is connected to the liquid inlet connector 310. The circulation body also includes a return pipe 520 connected in series with a second heat exchange structure 521. The first end of the return pipe 520 is connected to the liquid outlet connector 320, and the second end is connected to the coolant flushing assembly 530.

[0051] In the extraction pipe 510 and the return pipe 520, a circulation pump can be installed individually or in both to control the directional flow of the cooling liquid. The cooling liquid flows according to the attached... Figure 2 The arrow indicates the direction of the flow. The cooling liquid at the bottom of the second cooling filter body 500 first achieves heat exchange and cooling within the serpentine heat exchange device 300, and then enters the second heat exchange structure 521 to dissipate heat and cool the cooling liquid. The second heat exchange structure 521 can be a cooling structure with variable cooling effect, such as a separate oil cooling structure. The temperature of the cooling liquid passing through the second heat exchange structure 521 is controlled to be lower than the temperature of the cooling liquid inside the second cooling filter body 500. Finally, the cooling liquid with the lowest temperature is sprayed out from the cooling liquid flushing component 530 to achieve the final flushing and cooling of the irregular copper wire 700.

[0052] Through the above structural design, the cooling liquid can be cooled in a gradient manner. The second filter component 511 is also a detachable filter structure, which can filter out metal impurities and ensure that the lowest temperature cooling liquid sprayed from the coolant flushing component 530 is absolutely pure and free of impurities, ensuring that the surface of the irregular copper wire 700 is clean and free of impurities after cooling.

[0053] The coolant with the lowest temperature is sprayed out from the coolant flushing component 530, which mixes and cools the coolant on the left side of the second cooling filter body 500. At the same time, the liquid dripping from the serpentine heat exchanger 300 can raise the temperature of the coolant on the right side of the second cooling filter body 500. The coolant in the second cooling filter body 500 gradually decreases in temperature from right to left, which can better perform gradient cooling of the irregular copper wire 700. At the same time, the liquid in the second cooling filter body 500 can achieve efficient heat transfer, maintaining the overall temperature in the second cooling filter body 500 within a relatively suitable and stable range, thus achieving efficient and stable cooling.

[0054] An upwardly inclined drying device 600 is also provided on the outside of the second cooling filter body 500. The bottom edge of the guide wheel assembly 400 is located below the bottom of the drying device 600. A drying connector 610 is provided at the bottom of the drying device 600. Drying gas can be introduced into the drying device 600 through the drying connector 610 to dry the irregular copper wire 700. The bottom of the drying device 600 is connected to the second cooling filter body 500 and is in a liquid-sealed state. The drying gas flows outward synchronously with the irregular copper wire 700 to the other side to achieve synchronous drying.

[0055] The guide wheel assembly 400 can guide and bend the irregular copper wire 700, control the irregular copper wire 700 to be at the bottom, and immerse the irregular copper wire 700 at the bottom of the second cooling filter body 500 to achieve efficient cooling.

[0056] See attached document Figure 7 A special-shaped copper wire drawing and cooling device includes the above-mentioned special-shaped copper wire drawing and cooling device, and further includes a winding structure 820 and an unwinding structure 810. The conveying speed of the special-shaped copper wire 700 can be adjusted by controlling the unwinding structure 810 and the winding structure 820 to achieve stable drive control.

[0057] A temperature detection component 910 is installed at the bottom of the first cooling filter body 200 and electrically connected thereto. The temperature is detected by the temperature detection component 910 and the cooling rate of the first cooling filter body 200 is adjusted according to the temperature feedback result. A temperature detection component 920 is installed at the bottom of the serpentine heat exchanger 300 and electrically connected thereto. The temperature is detected by the temperature detection component 920 and the cooling rate of the serpentine heat exchanger 300 is adjusted according to the temperature feedback result. A temperature detection component 930 is installed on the side of the coolant flushing component 530 near the guide wheel assembly 400. The temperature detection component 930 is electrically connected to the winding structure 820 and the unwinding structure 810. The temperature is detected by the temperature detection component 930 and the winding rate of the unwinding structure 810 and the winding structure 820 is adjusted according to the temperature feedback result.

[0058] Through the above structural design, the cooling rate of each part and the winding speed of the shaped copper wire 700 can be controlled according to the detection results, ensuring that the shaped copper wire 700 can achieve gradient cooling within the predetermined temperature range, thus meeting the needs of the predetermined production process.

[0059] The temperature detection component mentioned above is a non-contact temperature detection element, which can detect the temperature state of the irregular copper wire 700 surface and obtain the cooling result of the irregular copper wire 700. Based on the detection result, the cooling rate and driving rate are adjusted and controlled. The temperature detection element mentioned above uses an existing temperature detection structure, which is existing technology and will not be described in detail here.

[0060] The invention will be further explained below with reference to specific cooling processes.

[0061] See attached document Figure 8 A process for cooling shaped copper wire drawing, using the aforementioned shaped copper wire drawing and cooling equipment, includes the following steps:

[0062] S1. When the temperature detection component 910 detects a temperature exceeding the first set range, the cooling effect of the first cooling filter body 200 is improved; when the temperature detection component 910 detects a temperature below the first set range, the cooling effect of the first cooling filter body 200 is reduced.

[0063] S2. When the temperature detected by temperature detection component 2 920 exceeds the second set range, the cooling effect of the serpentine heat exchanger 300 is improved; when the temperature detected by temperature detection component 2 920 is lower than the second set range, the cooling effect of the serpentine heat exchanger 300 is reduced.

[0064] S3. When the temperature detected by the temperature detection component 3 930 exceeds the third set range, the speed of the winding structure 820 and the unwinding structure 810 is reduced. When the temperature detected by the temperature detection component 3 930 is lower than the third set range, the speed of the winding structure 820 and the unwinding structure 810 is increased.

[0065] The first, second, and third temperature settings gradually decrease to achieve gradient cooling of the shaped copper wire 700. The unwinding structure 810 and the winding structure 820 can directly control the final low-temperature scouring cooling and also adjust the overall cooling rate. After the unwinding structure 810 and the winding structure 820 are adjusted, the drive control of the first cooling filter body 200 and the second cooling filter body 500 is synchronously and adaptively adjusted to ensure that the shaped copper wire 700 is within the predetermined cooling temperature range in the first cooling filter body 200 and the second cooling filter body 500, thereby achieving staged gradient cooling and meeting the requirements of efficient and stable cooling control.

[0066] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
