Description

Technical Field

[0001] This invention relates to an enameled wire, and more particularly to a processing technology and apparatus for ultra-fine enameled wire used in transformers. Background Technology

[0002] Currently, the processing technology for enameled wire includes sequential steps of drawing, annealing, enamel coating, and oiling. The oiling process involves applying a certain amount of lubricating oil to the surface of the enameled wire using a lubricating oil coating device. This makes the surface of the wire more lubricated and prevents scratching damage during subsequent winding and coiling processes. Based on this, existing lubricating oil coating devices mainly consist of a lubricating oil roller and a felt. In use, the lubricating oil roller first applies lubricating oil to the surface of the enameled wire by rotating, and then the felt is used to wipe the wire, removing excess lubricating oil and ensuring the lubricating oil is evenly applied to the surface.

[0003] However, the drawback of this structure is that although manufacturers can control the amount of lubricating oil applied to the enameled wire by adjusting the rotation speed of the lubricating oil roller, the amount of lubricating oil on the surface of the enameled wire after wiping with felt will differ from the predetermined amount, thus increasing the difficulty for manufacturers to adjust the amount of lubricating oil on the surface of the enameled wire. For example, when the amount of lubricating oil on the surface of the enameled wire increases, the amount of lubricating oil scraped off after the enameled wire passes through the felt also increases, and the lubricating oil remaining on the felt will affect the subsequent enameled wire, resulting in inconsistent lubricating oil application. Conversely, when the amount of lubricating oil on the surface of the enameled wire decreases, the felt is prone to completely scraping off the lubricating oil on the surface of the enameled wire, or applying the lubricating oil impregnated inside the felt back to the enameled wire. Under these limitations, it is difficult for existing lubricating oil coating devices to accurately control the amount of lubricating oil applied to the surface of the enameled wire.

[0004] The difference between transformer enameled wire and other enameled wires lies in the fact that during transformer assembly, tape needs to be wrapped around the surface of the wound transformer enameled wire. This tape is used to insulate, fix, and protect the wire, ensuring stable operation of the transformer. This necessitates that the amount of lubricating oil on the surface of the transformer enameled wire be controlled within a suitable range during the initial coating process. On the one hand, it's necessary to ensure the wire's lubricity to prevent frictional damage during processing, storage, and winding; on the other hand, it's crucial to avoid excessive lubricating oil causing the tape to fail to adhere properly.

[0005] Therefore, it is difficult for manufacturers to control the amount of lubricating oil on the surface of the enameled wire to ensure the later performance of the transformer enameled wire. Summary of the Invention

[0006] The purpose of this invention is to provide a processing technology and apparatus for ultra-fine enameled wires used in transformers. This technology improves the control over the amount of lubricating oil applied to the surface of the enameled wire.

[0007] The technical solution of this invention: A processing technology for ultra-fine enameled wire for transformers, comprising the following steps:

[0008] ① The copper wire is sequentially drawn, annealed, coated and baked to obtain an enameled wire of a specified diameter, which is called enameled wire A.

[0009] ② Coating the surface of copper wire A with lubricating oil yields enameled wire B;

[0010] ③ Pass the B enameled wire through the wiping roller, and the wiping roller wipes the lubricating oil on the surface of the B enameled wire by rotating after the B enameled wire passes through, thereby removing the excess lubricating oil on the surface of the enameled wire and obtaining the finished enameled wire.

[0011] In the aforementioned processing technology for ultra-fine enameled wire for transformers, the rotation direction of the wiping roller in step ③ is set in the same direction as the routing direction of the B enameled wire, and is used to increase the amount of lubricating oil coated on the B enameled wire after wiping.

[0012] In the aforementioned processing technology for ultra-fine enameled wire for transformers, the rotation direction of the wiping roller in step ③ is opposite to the routing direction of the B enameled wire, and is used to reduce the amount of lubricating oil coated on the B enameled wire after wiping.

[0013] The processing apparatus used in the aforementioned processing technology for ultra-fine enameled wire for transformers includes a wire drawing machine, an enameling machine, and a lubrication mechanism connected in sequence. The wire drawing machine is used to perform electrical annealing and wire drawing on copper wires. The enameling machine is used to coat and bake copper wires. The lubrication mechanism is used to coat the surface of the enameled wire with lubricating oil and wipe it.

[0014] The lubrication mechanism includes a lubricating oil tank, and a lubrication mechanism is provided inside the lubricating oil tank. An oil baffle box is provided on one side of the lubricating oil tank. A first guide wheel group, a wiping roller and a second guide wheel group are arranged sequentially inside the oil baffle box along the direction of the enameled wire. The surface of the wiping roller is covered with a cleaning sheet, and one end of the wiping roller extends to the outside of the oil baffle box and is connected to a drive motor.

[0015] In the aforementioned processing device, the first guide wheel group and the second guide wheel group have the same structure, both including multiple guide wheels arranged side by side along the length direction of the oil baffle box, and the inner side of the guide wheel is rotatably connected to the mounting shaft, and the two ends of the mounting shaft are connected to the oil baffle box.

[0016] In the aforementioned processing device, there is one wiping roller located below the enameled wire, and the top of the oil baffle box is provided with multiple wire guide ports for the enameled wire to extend into.

[0017] In the aforementioned processing device, the wiring port includes a first opening located side by side on the top of the oil baffle box and a second opening symmetrically arranged on the front and rear sides of the oil baffle box. The first opening and the second opening are interconnected. The lower end of the second opening is provided with a wiring hole, and the outer diameter of the wiring hole is larger than the width of the first opening and the second opening.

[0018] In the aforementioned processing device, the wiping roller includes an upper wiping roller and a lower wiping roller arranged side by side, with one end of the upper wiping roller and the lower wiping roller connected to each other via gears. The lower wiping roller extends to the outside of the oil baffle box and is connected to a drive motor. The oil baffle box includes a split upper box body and a lower box body. The first guide wheel group, the lower wiping roller, and the second guide wheel group are all arranged on the lower box body, and the upper wiping roller is rotatably connected to the upper box body.

[0019] In the aforementioned processing device, the first guide wheel group and the second guide wheel group are at the same height, and both the first guide wheel group and the second guide wheel group are connected to a lifting structure. The wiping roller and the first guide wheel group are staggered vertically and located on the upper and lower sides of the enameled wire, respectively. The oil baffle box includes a split upper box and a lower box. The first guide wheel group and the second guide wheel group are both set on the lower box. The wiping roller is rotatably connected to the upper box. The external gear of the wiping roller is connected to a drive motor.

[0020] In the aforementioned processing device, the lower box body has elongated holes at both ends for mounting shafts. The mounting shafts of the first guide wheel group and the second guide wheel group are connected to each other via an adjusting plate after passing through the elongated holes. The outside of the adjusting plate is fixedly connected with studs via adjusting nuts.

[0021] Compared with the prior art, the present invention has the following characteristics:

[0022] (1) By limiting the structure of the lubrication mechanism, the present invention enables the wiping roller to wipe the lubricating oil on the surface of the enameled wire by rotating. Based on this, the operator can control the contact area of ​​the enameled wire on the cleaning plate by adjusting the rotation direction and speed of the wiping roller, thereby achieving control over the amount of lubricating oil coated on the surface of the enameled wire.

[0023] (2) By defining the structure of the first guide wheel group, the wiping roller and the second guide wheel group, the working relationship between the first guide wheel group and the second guide wheel group can be used to position the wire routing position of the enameled wire, thereby ensuring the contact effect of the wiping roller on the enameled wire and the wiping stability.

[0024] (3) By setting up the oil baffle box, the oil baffle box can block the inner guide wheel, preventing the lubricating oil on the surface of the enameled wire from being thrown out to all sides with the rapid rotation of the guide wheel after it adheres to the surface of the guide wheel, thereby improving the lubrication effect.

[0025] Therefore, the present invention can improve the control effect on the amount of lubricating oil coated on the surface of enameled wire. Attached Figure Description

Detailed Implementation

[0033] The present invention will be further described below with reference to the accompanying drawings and embodiments, but this should not be construed as limiting the present invention.

[0034] Example 1. A processing method for ultra-fine enameled wire for transformers, comprising the following steps:

[0035] ① The copper wire is sequentially drawn, annealed, coated and baked to obtain an enameled wire of a specified diameter, which is called enameled wire A.

[0036] ② Coating the surface of copper wire A with lubricating oil yields enameled wire B;

[0037] ③ Pass the B enameled wire through a wiping roller with a cleaning layer on its surface. After the B enameled wire passes through, the wiping roller rotates to wipe the lubricating oil on the surface of the B enameled wire, thereby removing excess lubricating oil from the surface of the enameled wire and obtaining the finished enameled wire.

[0038] In step ③, the rotation direction of the wiping roller and the routing direction of the B enameled wire are either in the same direction or opposite. When the rotation direction of the wiping roller and the routing direction of the B enameled wire are in the same direction, the faster the rotation speed of the wiping roller, the more lubricating oil is applied to the B enameled wire after wiping, until the rotation speed of the wiping roller and the routing speed of the B enameled wire are the same. When the rotation direction of the wiping roller and the routing direction of the B enameled wire are opposite, the faster the rotation speed of the wiping roller, the less lubricating oil is applied to the B enameled wire after wiping.

[0039] In this embodiment, a wiping roller with a cleaning layer on its surface is used instead of the existing felt to wipe the enameled wire. This allows the wiping roller to adjust the contact length between the enameled wire and the cleaning layer when it passes through by changing its rotation speed, thereby controlling the wiping effect of the wiping roller on the surface of the enameled wire and achieving control over the amount of lubricating oil applied.

[0040] Example 2. Processing apparatus, configured as follows: Figure 1 and 2 As shown, it includes a wire drawing machine, an enameling machine, and a lubrication mechanism connected in sequence. The wire drawing machine is used to perform electrical annealing and wire drawing on copper wires. The enameling machine is used to coat and bake copper wires. The lubrication mechanism is used to coat the surface of the enameled wire with lubricating oil and wipe it.

[0041] The lubrication mechanism includes a lubricating oil tank 1, which houses the lubrication mechanism. An oil baffle box 2 is located on one side of the lubricating oil tank 1. Inside the oil baffle box 2, along the direction of the enameled wire, a first guide wheel assembly 3, a wiping roller 4, and a second guide wheel assembly 5 are sequentially arranged. The surface of the wiping roller 4 is covered with a cleaning sheet 6, which can be made of felt or sponge. Multiple slits are arranged side-by-side on the cleaning sheet 6 to allow the enameled wire to pass through, ensuring effective wiping after the wire passes through the center of the slits. One end of the wiping roller 4 extends to the outside of the oil baffle box 2 and is connected to a drive motor 7. The drive motor 7 can adjust its speed via a frequency converter, thereby adjusting the contact length between the cleaning sheet 6 and the enameled wire when the wire passes through.

[0042] The first guide wheel group 3 and the second guide wheel group 5 have the same structure. Both include multiple guide wheels 9 arranged side by side along the length of the oil baffle box 2. Each guide wheel 9 corresponds to an enameled wire. When in use, the guide wheel 9 rotates with the enameled wire. The inner side of the guide wheel 9 is rotatably connected to the mounting shaft 10. The two ends of the mounting shaft 10 are connected to the oil baffle box 2.

[0043] The lubrication mechanism includes a lubricating oil roller 6. The lower end of the lubricating oil roller 6 is immersed in the lubricating oil in the lubricating oil tank 1. Multiple oil grooves are arranged side by side on the surface of the lubricating oil roller. One end of the lubricating oil roller is connected to a lubrication motor via a gear transmission mechanism. The lubrication motor can adjust its own speed through a frequency converter, thereby controlling the amount of lubricating oil applied to the enameled wire.

[0044] The number of wiping rollers 4 is one and it is located below the enameled wire. The top of the oil baffle box 2 is provided with multiple wire passages 8 for the enameled wire to extend into.

[0045] The wiring port 8 includes a first opening 801 located side-by-side on the top of the oil baffle box 2 and a second opening 802 symmetrically arranged on the front and rear sides of the oil baffle box 2. The first opening 801 and the second opening 802 are interconnected. The lower end of the second opening 802 is provided with a circular wiring hole 803. The width of the first opening 801 and the second opening 802 is slightly larger than the diameter of the enameled wire. The outer diameter of the wiring hole 803 is larger than the width of the first opening 801 and the second opening 802. When the enameled wire is being routed, it passes through the middle of the wiring hole 803. The wiring hole 803 can prevent the enameled wire from contacting the side wall of the oil baffle box 2 during the route. When the lubrication device is in use, a felt sheet can be placed on the top of the oil baffle box 2 to prevent lubricating oil from splashing outward from the first opening 801.

[0046] The oil baffle box 2 has a support frame bolted to both ends of the support member, and a base connected to the bottom of the oil baffle box 2. The base and the oil baffle box 2 are nested inside and outside and connected to each other by self-tapping screws or pins. There is a gap between the base and the support frame. When cleaning, the operator can directly remove the connecting part and pull the base out from under the oil baffle box 2.

[0047] In this embodiment, lubricating oil is first applied to the surface of the enameled wire through the cooperation of the lubricating oil tank 1 and the lubrication mechanism, allowing the wire to enter the oil-retaining box 2 after being soaked in the lubricating oil. Once inside the oil-retaining box 2, the surface of the wire is wiped by the cooperation of the wiping roller 4 and the cleaning plate 6, thereby removing some of the lubricating oil. Based on this, the manufacturer can adjust the rotation speed of the wiping roller 4, thereby changing the contact length between the cleaning plate 6 and the wire and the wiping effect on the lubricating oil surface, thus achieving adjustment of the amount of lubricating oil applied to the wire surface.

[0048] During the wire routing process, the guide wheels 9 on both sides of the wiping roller 4 can guide and limit the height of the enameled wire, thereby ensuring the wiping effect of the cleaning plate 6 on the enameled wire; the cooperation between the oil baffle box 2 and the wire routing port 8 can block the inner guide wheel 9, thereby preventing the guide wheel 9 from splashing outwards as it rotates after the lubricating oil on the surface of the enameled wire adheres to it, thus ensuring the cleanliness of the surrounding environment.

[0049] Example 3. Processing apparatus, configured as follows: Figure 3 and 4 As shown, it includes a wire drawing machine, an enameling machine, and a lubrication mechanism connected in sequence. The wire drawing machine is used to perform electrical annealing and wire drawing on copper wires. The enameling machine is used to coat and bake copper wires. The lubrication mechanism is used to coat the surface of the enameled wire with lubricating oil and wipe it.

[0050] The lubrication mechanism includes a lubricating oil tank 1, which contains the lubrication mechanism. An oil baffle box 2 is provided on one side of the lubricating oil tank 1. Inside the oil baffle box 2, along the wire routing direction of the enameled wire, a first guide wheel group 3, a wiping roller 4, and a second guide wheel group 5 are arranged in sequence. The surface of the wiping roller 4 is covered with a cleaning sheet 6, which can be made of felt or sponge. One end of the wiping roller 4 extends to the outside of the oil baffle box 2 and is connected to a drive motor 7. The drive motor 7 can adjust its own speed through a frequency converter, thereby adjusting the contact length between the cleaning sheet 6 and the enameled wire when the wire passes through.

[0051] The first guide wheel group 3 and the second guide wheel group 5 have the same structure. Both include multiple guide wheels 9 arranged side by side along the length of the oil baffle box 2. Each guide wheel 9 corresponds to an enameled wire. When in use, the guide wheel 9 rotates with the enameled wire. The inner side of the guide wheel 9 is rotatably connected to the mounting shaft 10. The two ends of the mounting shaft 10 are connected to the oil baffle box 2.

[0052] The lubrication mechanism includes a lubricating oil roller 6. The lower end of the lubricating oil roller 6 is immersed in the lubricating oil in the lubricating oil tank 1. Multiple oil grooves are arranged side by side on the surface of the lubricating oil roller. One end of the lubricating oil roller is connected to a lubrication motor via a gear transmission mechanism. The lubrication motor can adjust its own speed through a frequency converter, thereby controlling the amount of lubricating oil applied to the enameled wire.

[0053] The wiping roller 4 includes an upper wiping roller 401 and a lower wiping roller 402 arranged side by side. One end of the upper wiping roller 401 and the lower wiping roller 402 are connected to each other by gears. The lower wiping roller 402 extends to the outside of the oil baffle box 2 and is connected to the drive motor 7. The oil baffle box 2 includes a split upper box and a lower box. A wire passage 8 for enameled wire to pass through is formed between the upper box and the lower box. The two ends of the upper box and the lower box are connected to each other by bolts. The first guide wheel group 3, the lower wiping roller 402 and the second guide wheel group 5 are all arranged on the lower box. The upper wiping roller 401 is rotatably connected to the upper box.

[0054] Compared to Example 2, this example symmetrically arranges the upper wiping roller 401 and the lower wiping roller 402 on the upper and lower sides of the enameled wire. This allows the cleaning plate 6 to fully adhere to the enameled wire by the mutual squeezing of the two wiping rollers, improving the wiping effect on the lubricating oil on the wire surface. Furthermore, by setting the oil baffle box 2 as a split structure, operators can first remove the upper box and allow the enameled wire to pass sequentially through the first guide wheel group 3, the lower wiping roller 402, and the second guide wheel group 5 from above during wire routing. Then, the upper box is installed on the lower box, and the gears at the ends of the upper wiping roller 401 and the lower wiping roller 402 mesh with each other, ensuring synchronous rotation during use.

The surface of the wiping roller 4 is covered with a cleaning sheet 6, which can be made of felt or sponge. Multiple U-shaped grooves for the enameled wire to pass through are arranged side by side on the cleaning sheet 6, so that the enameled wire can be wiped around by the cleaning sheet 6 after passing through the U-shaped grooves, ensuring the wiping effect. One end of the wiping roller 4 extends to the outside of the oil baffle box 2 and is connected to a drive motor 7. The drive motor 7 can adjust its own speed through a frequency converter, thereby adjusting the contact length between the cleaning sheet 6 and the enameled wire when the wire passes through.
