Abstract
Description
Technical Field
[0001] This utility model relates to the field of copper wire production technology, and in particular to a stretching device for copper wire production and processing. Background Technology
[0002] As the core component of conductors, copper wire requires multiple stretching operations on an initial copper rod to meet specific specifications. The copper wire stretching device includes a preheating mechanism, a lubrication and cooling structure, a drawing die, and a conveying mechanism. During the multiple stretching operations within the device, the copper wire must be immersed in lubricating fluid for lubrication and cooling to reduce resistance as it passes through the drawing die and lower the risk of breakage.
[0003] Repeated immersion of copper wire in lubricating fluid for lubrication and cooling will carry copper powder generated during the stretching process into the lubricating fluid. If copper powder adheres to the surface of the copper wire during stretching, it will scratch the surface of the copper wire and increase the risk of breakage. Since the copper powder in the lubricating fluid is relatively fine and the lubricating fluid is relatively viscous, the efficiency of removing copper powder by ordinary filtration methods is relatively low. In addition, it is necessary to stop the machine frequently to clean the copper powder or replace the lubricating fluid, which makes it difficult to use for a long time at a time and has a significant impact on the stretching efficiency of copper wire. Utility Model Content
[0004] In view of this, the purpose of this utility model is to propose a stretching device for copper wire production and processing, so as to solve the problem that it is difficult to use for a long time at a time, which has a great impact on the stretching efficiency of copper wire.
[0005] To achieve the above objectives, this utility model provides a stretching device for copper wire production and processing, including a lubrication tank and a conveying part for immersing copper wire into the lubrication tank. An electromagnetic rod installed inside a lubrication tank includes a sealing sleeve coaxially fixed inside the lubrication tank and an electromagnetic coil coaxially installed inside the sealing sleeve, used to generate a strong magnetic field to drive copper powder toward the arc-shaped inner wall of the lubrication tank. The retrieval unit located inside the lubrication tank includes a retrieval ring that is coaxially slidably disposed inside the lubrication tank. The outer edge of the retrieval ring contacts the inner wall of the lubrication tank, and a filter ring groove is provided on the top of the retrieval ring. The two vertical supports on the lubrication tank are equipped with a drive component for raising and lowering the retrieval ring, thereby scraping off the copper powder adhering to the inner wall of the lubrication tank.
[0006] Preferably, the height of the sealing sleeve is greater than the level of the lubricating fluid in the lubrication tank, and the two ends of the electromagnetic coil pass through the top of the sealing sleeve and are connected to an external power source.
[0007] Preferably, a retaining ring is fixedly provided at the inner edge of the top of the retrieval ring, and the height of the retaining ring is greater than the depth of the filter ring groove.
[0008] Preferably, the filter ring groove and the outer edge of the top of the retrieval ring are provided with a chamfered surface, and the filter ring groove and the retrieval ring are coaxial.
[0009] Preferably, the driving component includes a fixed rack and a telescopic cylinder fixed vertically on a vertical support. A gear frame is fixedly provided at the output end of the telescopic cylinder. A linkage tooth is rotatably provided inside the gear frame. A guide sleeve is provided at the bottom of the vertical support. A movable rack is vertically slidably inserted inside the guide sleeve. The two sides of the tooth surface of the linkage tooth mesh with the movable rack and the fixed rack, respectively. The bottom end of the movable rack is fixedly provided at the top of the enclosure ring.
[0010] Preferably, the telescopic cylinder is radially located between the moving rack and the fixed rack, and the output end of the telescopic cylinder faces vertically downward.
[0011] Preferably, the length of the fixed rack is equal to the extension length of the telescopic cylinder, and the sum of the length of the fixed rack and the extension length of the telescopic cylinder is less than the length of the movable rack.
[0012] Preferably, the lifting distance of the movable rack is greater than the height of the lubricating fluid in the lubrication tank.
[0013] The beneficial effects of this utility model are: This invention generates a strong electromagnetic field using an electromagnetic rod. Since copper powder is a diamagnetic material, it generates induced eddy currents in an alternating magnetic field, which in turn generates a reverse magnetic field. This forms a Lorentz force that repels the magnetic field source and pushes the copper powder towards a low magnetic field region. This allows the copper powder to be pushed onto the arc-shaped inner wall of the lubrication tank in real time and accumulate there. This greatly extends the cleaning or replacement cycle of the lubricant and reduces its frequency. During cleaning, the scooping ring is slowly raised to scoop the copper powder on the inner wall of the lubrication tank into the filter ring groove and then retrieve it, making it convenient for centralized cleaning.

[0017] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments.

[0019] like Figures 1 to 3As shown, a stretching device for copper wire production and processing includes a lubrication tank 1 and a conveying section 4 for immersing copper wire into the lubrication tank 1. The lubrication tank 1 contains a lubricating fluid for lubricating and cooling the copper wire. The conveying section 4 includes two outer supports 46 fixed to the outside of the lubrication tank 1. A guide wheel 45 is provided on the top of the outer supports 46. A support frame 41 is fixed on the top of one of the outer supports 46. One end of the support frame 41 extends into the interior of the lubrication tank 1 and is located inside the lubricating fluid. Two guide wheels 42 are laterally rotatable on one side of the support frame 41, and a tensioning wheel 43 is rotatably provided on the bottom of the same side of the support frame 41. A wire drawing part is fixed on one side of the support frame 41. The drawing die 44 is vertically positioned between one of the guide rollers 42 and the tension roller 43. The copper wire passes horizontally through the interior of one of the lead rollers 45 and into the interior of the guide roller 42 next to it. Then, it goes down 90° from the top of the guide roller and into the interior of the tension roller 43. From the bottom of the tension roller 43, it goes up 180° and through the hole of the drawing die 44. Then, it goes into the other guide roller 42, goes down 90° from its surface and horizontally into the interior of the other lead roller 45. Then, it is guided to the next process. Both the tension roller 43 and the drawing die 44 are located below the surface of the lubricating fluid to improve the lubrication effect of the lubricating fluid on the copper wire.
[0020] The electromagnetic rod 2, located inside the lubrication tank 1, includes a sealing sleeve 21 coaxially fixed inside the lubrication tank 1 and an electromagnetic coil 22 coaxially located inside the sealing sleeve 21. The height of the sealing sleeve 21 is greater than the height of the lubricating fluid in the lubrication tank 1. The two ends of the electromagnetic coil 22 pass through the top of the sealing sleeve 21 and are connected to an external power source to generate a strong magnetic field. Since copper powder is a diamagnetic material, it generates induced eddy currents in the alternating magnetic field, which in turn generates a reverse magnetic field, forming a Lorentz force that repels the magnetic field source and is pushed to the low magnetic field region by the magnetic repulsion force. This is used to generate a strong magnetic field to drive the copper powder toward the arc-shaped inner wall of the lubrication tank 1.
[0021] The retrieval unit 3, located inside the lubrication tank 1, includes a retrieval ring 31 that is coaxially slidably disposed inside the lubrication tank 1. The outer edge of the retrieval ring 31 contacts the inner wall of the lubrication tank 1. A filter ring groove 32 is provided at the top of the retrieval ring 31. A retaining ring is fixedly provided at the inner edge of the top of the retrieval ring 31. The height of the retaining ring is greater than the depth of the filter ring groove 32. A chamfer is provided between the filter ring groove 32 and the outer edge of the top of the retrieval ring 31. The filter ring groove 32 and the retrieval ring 31 are coaxial.
[0022] The two vertical supports 34 on the lubrication tank 1 are equipped with a drive component 33 for driving the retrieval ring 31 to rise and fall, so as to scrape off the copper powder attached to the inner wall of the lubrication tank 1. The drive component 33 drives the retrieval ring 31 to rise and fall at a relatively slow and stable speed, so as to avoid the relative displacement speed between the retrieval ring 31 and the lubricating fluid being too large, which would cause the copper powder falling into the filter ring groove 32 to be flushed out and affect the retrieval effect.
[0023] like Figure 3 and Figure 4 As shown, the driving component 33 includes a fixed rack 332 and a telescopic cylinder 333 vertically fixed on the vertical support 34. The output end of the telescopic cylinder 333 is fixedly provided with a gear frame 334. The gear frame 334 has a rotatable linkage gear 335 inside. The bottom of the vertical support 34 is provided with a guide sleeve 336. A movable rack 331 is vertically slidably inserted inside the guide sleeve 336. The lifting distance of the movable rack 331 is greater than the liquid level of the lubricating fluid contained in the lubrication tank 1. The telescopic cylinder 333 is radially located between the movable rack 331 and the fixed rack 332. Furthermore, the output end of the telescopic cylinder 333 is vertically downward, and the two sides of the tooth surface of the linkage tooth 335 are respectively engaged with the moving rack 331 and the fixed rack 332. The bottom end of the moving rack 331 is fixedly set on the top of the enclosure ring. The length of the fixed rack 332 is equal to the telescopic length of the telescopic cylinder 333, and the sum of the length of the fixed rack 332 and the telescopic length of the telescopic cylinder 333 is less than the length of the moving rack 331. With this design, the retrieval ring 31 can be driven to rise to a greater height by only the shorter telescopic cylinder 333, thus reducing the space occupation rate of the telescopic cylinder 333.
[0024] Working principle: The electromagnetic coil 22 is always energized during copper wire stretching and copper powder retrieval. This not only drives the copper powder to the arc-shaped inner wall of the lubrication tank 1 during long-term use, reducing the amount of copper powder carried by the copper wire when repeatedly immersed in the lubricating fluid, but also allows the copper powder to concentrate and adhere to the inner wall of the lubrication tank 1. This facilitates cleaning by controlling the drive component 33 to drive the retrieval ring 31 to rise slowly and uniformly, avoiding a large relative displacement speed between the retrieval ring 31 and the lubricating fluid, which could wash out the copper powder that has fallen into the filter ring groove 32 and affect the retrieval effect. The retrieval ring 31 stops when it is completely separated from the lubricating fluid, allowing cleaning personnel to concentrate on cleaning the copper powder in the filter ring groove 32. This extends the single-use life and replacement cycle of the lubricating fluid, thereby reducing the frequency of lubricating fluid cleaning or replacement and reducing the impact of cleaning on the copper wire stretching efficiency.
