Description

Technical Field

[0001] The invention relates to the technical field of electromagnetic wire preparation, in particular to a corona-resistant and flame-retardant electromagnetic wire and a preparation device thereof. Background Art

[0002] Electromagnetic wire (also known as winding wire) is an insulated wire used to manufacture coils or windings in electrical products (such as motors, transformers, inductors, etc.). It is an important basic material in the fields of electricity, electronics, communications, transportation, etc., and is mainly used in motors, transformers and inverters. According to the manufacturing material, it can be divided into enameled wire and wrapped wire. The production of electromagnetic wire requires raw material preparation, wire drawing, water washing, annealing, straightening, impregnation, drying and winding. Straightening mainly uses straightening rollers or straightening wheels to apply pressure to the wire, and restore the straightness of the wire through elastic deformation.

[0003] However, the current electromagnetic wire needs to be straightened before annealing and impregnation during production. The straightening process is completed by passing the electromagnetic wire through two upper and lower rollers. Before the flat electromagnetic wire is straightened, there will be a layer of oxide film on the surface of the electromagnetic wire. If the oxide film is not pre-treated by chemical or physical means before straightening, the surface of the electromagnetic wire will become uneven, which makes it difficult to provide good conditions for subsequent straightening. The presence of the oxide film will cause the current to be concentrated in a local area, and the current transmission will not be smooth, causing local overheating and accelerating material aging. In order to avoid foreign matter on the surface of the electromagnetic wire during straightening, it will be washed with water. After washing, the electromagnetic wire is directly straightened. There will be moisture residue on its surface during washing. If it is not treated, it is easy to drip onto other workstations or pressure rollers, causing it to rust and increase the resistance to straightening. Silicone oil or other trace lubricants are not applied to the surface of the electromagnetic wire before straightening, making it difficult to reduce the friction damage caused to the electromagnetic wire during the straightening process.

[0015] The beneficial effects of the present invention are:

[0016] (1) The corona-resistant and flame-retardant electromagnetic wire and its preparation device described in the present invention have a grinding mechanism installed on the bracket and a driving mechanism installed on the straightening mechanism. The driving mechanism is connected to the grinding mechanism. When the electromagnetic wire body is straightened, one of the gears 2 drives the connecting rod to rotate. Since the fixed frame is vertically limited by the slide bar, when the gear 2 drives the connecting rod to rotate, the connecting rod drives the fixed frame to move back and forth in the horizontal direction, and then the slide bar drives the movable frame to move back and forth inside the slide slot, and finally the grinding block at the end of the rotating plate grinds the oxide film on the electromagnetic wire body.

As the electromagnetic wire body is transported, the sponge sleeve can absorb the cleaning water, which is convenient for applying silicone oil to prevent parts from rusting. When the sliding rod drives the grinding block to grind the electromagnetic wire body, the push rod moves back and forth accordingly. When the push rod collides with the outer shell, the sponge sleeve is squeezed to drain water.

[0018] (3) The corona-resistant and flame-retardant electromagnetic wire and its preparation device described in the present invention have an oiling mechanism on the outer wall of the fixed box. When the electromagnetic wire body is transported, two sponge brushes can absorb the silicone oil in the oil tank through the oil-absorbing cotton rope.

When the sliding rod drives the push rod to press the shell to extend the limit rod, the limit rod will squeeze the tooth plate, and the tooth plate will slide on the outside of the support column, thereby realizing the rotation of a gear four. Since the two gears four are engaged, the two gears four will also be driven to rotate, so that the two sponge brushes can contact the electromagnetic wire body at different positions, which is conducive to the comprehensive application of silicone oil on the electromagnetic body.

The two fixed plates 201 are both connected to a plurality of sliders 204 for sliding relative to each other at equal distances. An upper pressure roller 206 is rotatably connected between the two opposite sliders 204. The two fixed plates 201 are both threadedly connected to a plurality of screws 205 rotatably connected to the sliders 204. Both ends of the upper pressure roller 206 are keyed to a gear 2 203. The gear 1 202 on the same side is meshed with the gear 2 203. The bracket 1 is fixedly connected to a mounting plate 207 parallel to the fixed plate 201. A motor 208 is installed on the mounting plate 207. A plurality of gears 3 210 are rotatably connected between one of the fixed plates 201 and the mounting plate 207. The gear 3 210 The gears 3 210 are key-connected to the motor 208, and the gears 3 210 are located between two adjacent gears 1 202, and the gears 3 210 and the gears 1 202 are meshed with each other; the driving mechanism 3 includes a connecting rod 302, one of the gears 2 203 is fixedly connected to the connecting rod 302, and two support frames 301 are mounted on the bracket 1 by screws, one of the support frames 301 has an opening on the side, and a sliding rod 304 is slidably connected between the two support frames 301, and the sliding rod 304 is fixedly connected to the mobile frame 402, and a fixed frame 303 is vertically fixedly connected to the sliding rod 304 away from the mobile frame 402, and one end of the connecting rod 302 is embedded in the interior of the fixed frame 303;When the electromagnetic wire body 504 is pressed straight, the electromagnetic wire body 504 is inserted from the fixed box 401 between the upper pressing roller 206 and the lower pressing roller 209. The two rubber rollers 503 located on the side wall of the fixed box 401 can initially press and guide the electromagnetic wire body 504. When pressing straight, the motor 208 is started to drive one of the gears 3 210 on the outside of the mounting plate 207 to rotate. Since the gears 3 210 are engaged with each other among the multiple gears 1 202, when one of the gears 3 210 is driven, the remaining gears 1 202 and gear 3 210 are rotated. 0 will be transmitted one by one, and the rotation directions of multiple gears 1 202 are the same. Since gear 1 202 is meshed with gear 2 203, gear 1 202 drives gear 2 203 to rotate, and the directions are opposite. Then, the upper pressing roller 206 and the lower pressing roller 209 are rotated at the same time, and the electromagnetic wire body 504 between the two can be straightened, and the electromagnetic wire body 504 can be transported. When straightening, the outermost gear 2 203 will drive the connecting rod 302 to rotate. Since the fixed frame 303 on the slide bar 304 is limited in the vertical direction, One end of the connecting rod 302 is inserted into the interior of the fixed frame 303. When the connecting rod 302 rotates, the fixed frame 303 is swung back and forth in the horizontal direction, and the sliding rod 304 moves back and forth horizontally inside the support frame 301, thereby realizing that the sliding rod 304 drives the movable frame 402 to move inside the slide groove 403. Since the electromagnetic wire body 504 passes through a grinding block 406, the connecting plate 404 moves along with it when the movable frame 402 moves back and forth, and finally realizes that the grinding block 406 at the end of the rotating plate 405 oxidizes the surface of the electromagnetic wire body 504. The polished magnet wire body 504 provides excellent conditions for subsequent straightening. The oxide film polishing prevents current concentration in localized areas, ensuring smooth current transmission, preventing local overheating and reducing material aging. Furthermore, the polishing block 406 can be adjusted or replaced based on the thickness of the magnet wire body 504. Simply remove and replace the connecting plate 404. To adjust the polishing block 406 to a different diameter, simply pull out the pin 408 on the connecting plate 404 and rotate the rotating plate 405. Once selected, reinsert the pin 408 into the socket 407.

[0033] Specifically, refer to Figure 4 、 Figure 5 、 Figure 6 and Figure 7As shown, the fixed box 401 is provided with a water washing mechanism 5, and the water washing mechanism 5 includes a water pipe 501, a rubber roller 503 and an electromagnetic wire body 504. Two rubber rollers 503 are installed on the sides of the fixed box 401 relative to each other, and an electromagnetic wire body 504 is provided between the two rubber rollers 503. The electromagnetic wire body 504 is inserted into the interior of the fixed box 401, and the electromagnetic wire body 504 is inserted between the upper pressure roller 206 and the lower pressure roller 209. A water pipe 501 with an outlet opposite to the electromagnetic wire body 504 is installed on the fixed box 401, and the water pipe 501 is vertically arranged between the slide bar 304; the water washing mechanism 5 also includes a side plate 505 and a water diversion box 502, and the inner wall of the fixed box 401 is fixedly connected to the side plate 505. A water separation box 502 located at the bottom of the water pipe 501 is installed on the side plate 505, and a plurality of water leakage holes 506 are provided inside the water separation box 502; a water wiping mechanism 6 is provided inside the fixed box 401, and the water wiping mechanism 6 includes a sponge cover 601, the inner wall of the fixed box 401 is bonded with a sponge cover 601, and the end of the sponge cover 601 is fixedly connected to a shell 603, and the sponge cover 601 and the shell 603 are sleeved on the outside of the electromagnetic wire body 504; the water wiping mechanism 6 also includes a push rod 602, a limit rod 604 and a spring 605, and the side wall of the shell 603 is fixedly connected to the limit rod 604 that is slidably connected to the fixed box 401, and a spring 605 is clamped between the shell 603 and the fixed box 401. The side of the slide bar 304 is fixedly connected with a push rod 602, and the push rod 602 passes through the interior of the slide groove 403, and the end of the push rod 602 is located on the right side of the shell 603; after the oxide film on the surface of the electromagnetic wire body 504 is polished, it needs to be washed with water, and as the polished part of the electromagnetic wire body 504 is transported, it will pass through the bottom of the water diversion box 502, and the water pipe 501 will be connected to the water source to spray water into the interior of the water diversion box 502. The water diversion box 502 can discharge water from multiple leakage holes 506 to clean the electromagnetic wire body 504 to prevent foreign matter from affecting the flatness of the straightening or foreign matter from being embedded in the interior of the electromagnetic wire body 504. After washing, the electromagnetic wire body 504 will pass through the interior of the sponge cover 601, and the sponge cover 601 can clean the electromagnetic wire The moisture on the main body 504 is absorbed and wiped away to avoid affecting the application of silicone oil. When the slide rod 304 drives the movable frame 402 to move, it will also drive the push rod 602 to move back and forth at the slide groove 403. When the push rod 602 moves to the left, it will push the shell 603 to squeeze the sponge cover 601, squeeze out the moisture inside the sponge cover 601, and be more conducive to absorbing subsequent moisture. When the shell 603 is squeezed, the limit rod 604 will extend out of the fixed box 401, and the spring 1 605 is compressed. When the push rod 602 moves to the right, the spring 1 605 opens, and the limit rod 604 returns to the inside of the fixed box 401 again to realize the sponge cover 601 opening to absorb water, thereby preventing water from dripping onto the upper pressure roller 206 and the lower pressure roller 209 to cause rust, which is conducive to the application of silicone oil in the next process.

[0034] Specifically, refer to Figure 1 、 Figure 4 、 Figure 5 、 Figure 7 、 Figure 8 、 Figure 9 and Figure 10 As shown, the outer wall of the fixed box 401 is provided with an oiling mechanism 7, and the oiling mechanism 7 includes an oil tank 701. The outer wall of the fixed box 401 is installed with an oil tank 701. The side wall of the fixed box 401 is fixedly connected to a top frame 702. The bottom of the top frame 702 is rotatably connected to two gears 703. The two gears 703 are engaged with each other. The bottoms of the two gears 703 are both bonded with sponge brushes 704 with an I-shaped cross-section. The electromagnetic wire body 504 is inserted into the two Between the sponge brushes 704, the bottoms of the two sponge brushes 704 are fixedly connected with oil-absorbing cotton ropes 705; the oiling mechanism 7 also includes a support column 707, the outer wall of the fixed box 401 is fixedly connected with the support column 707, the support column 707 is a rectangular parallelepiped structure, the outer wall of the support column 707 is slidably connected with a rack 706 with an L-shaped cross-section, the rack 706 is meshed with one of the gears 703, and a spring is clamped between the rack 706 and the fixed box 401 Spring 2 708, the rack 706 is arranged opposite to the limit rod 604; the interior of the oil tank 701 is filled with silicone oil, and the oil-absorbing cotton rope 705 can absorb the silicone oil inside it into the interior of the two sponge brushes 704. After the electromagnetic wire body 504 is cleaned of water and extends to the outside of the fixed box 401, it will pass through the two sponge brushes 704. The silicone oil on the sponge brushes 704 will be smeared on the electromagnetic wire body 504, which can reduce the friction damage caused by the electromagnetic wire during the straightening process. When the push rod 602 moves to the left The extrusion limit rod 604 extends out of the outer wall of the fixed box 401. At this time, the limit rod 604 can be squeezed with the rack 706 on the outer wall of the support column 707, and the spring 2 708 is opened. Since the rack 706 is engaged with the gear 4 703, when the rack 706 is driven to move back and forth in the horizontal direction, the two gears 4 703 are rotated relative to each other, and the two sponge brushes 704 can be changed to contact the electromagnetic wire body 504 in different positions in a cycle, which is conducive to the uniform application of silicone oil and always ensures that there is silicone oil on the sponge brush 704.

[0035] When the present invention is used, first, when straightening the electromagnetic wire body 504, the electromagnetic wire body 504 is inserted from the fixed box 401 between the upper pressing roller 206 and the lower pressing roller 209. The two rubber rollers 503 located on the side wall of the fixed box 401 can initially straighten and guide the electromagnetic wire body 504. When straightening, the motor 208 is started to drive one of the gears 3 210 on the outside of the mounting plate 207 to rotate. Since the gears 3 210 are engaged with each other among the multiple gears 1 202, when one of the gears 3 210 is driven, the remaining gears 2 02 and gear three 210 will be transmitted one by one, and the rotation directions of multiple gears 1 202 are the same. Since gear 1 202 is engaged with gear 2 203, gear 1 202 drives gear 2 203 to rotate, and the directions are opposite. Then, the upper pressing roller 206 and the lower pressing roller 209 are rotated at the same time, and the electromagnetic wire body 504 between the two can be pressed straight, and the electromagnetic wire body 504 can be transported. When pressing straight, the outermost gear 203 will drive the connecting rod 302 to rotate. Since the fixed frame 303 on the slide bar 304 is vertical, the electromagnetic wire body 504 can be conveyed. The connecting rod 302 is limited in position, and one end of the connecting rod 302 is inserted into the interior of the fixed frame 303. When the connecting rod 302 rotates, the fixed frame 303 is swung back and forth in the horizontal direction, and the sliding rod 304 moves back and forth horizontally inside the support frame 301, thereby realizing that the sliding rod 304 drives the movable frame 402 to move inside the slide groove 403. Since the electromagnetic wire body 504 passes through a grinding block 406, the connecting plate 404 moves along with it when the movable frame 402 moves back and forth, and finally realizes that the grinding block 406 at the end of the rotating plate 405 is on the electromagnetic wire body 504. The oxide film is polished, and the polished electromagnetic wire body 504 can provide good conditions for subsequent straightening. After the oxide film is polished, the current will not be concentrated in a local area, the current transmission is smooth, and local overheating will not occur, reducing material aging. The polishing block 406 can be adjusted or replaced according to the thickness of the electromagnetic wire body 504. The connection plate 404 can be replaced and disassembled. If the polishing block 406 of different diameters is adjusted, it is only necessary to pull out the pin 408 on the connection plate 404 and rotate the rotating plate 405. After selection, the pin 408 is inserted into the inside of the jack 407 again.

[0036] Then, after the oxide film on the surface of the electromagnetic wire body 504 is polished, it needs to be washed with water. As the conveyed and polished part of the electromagnetic wire body 504 passes through the bottom of the water separation box 502, the water pipe 501 is connected to the water source to spray water into the interior of the water separation box 502. The water separation box 502 can discharge water from multiple leaking holes 506 to clean the electromagnetic wire body 504 to prevent foreign matter from affecting the flatness of the straightening or foreign matter from being embedded in the interior of the electromagnetic wire body 504. After washing, the electromagnetic wire body 504 will pass through the interior of the sponge cover 601. The sponge cover 601 can absorb and wipe the moisture on the electromagnetic wire body 504 to avoid affecting the application of silicone oil. When the movable frame 402 is driven to move, the push rod 602 is also driven to move back and forth in the slide groove 403. When the push rod 602 moves to the left, it pushes the shell 603 to squeeze the sponge cover 601, squeezing out the moisture inside the sponge cover 601, which is more conducive to absorbing subsequent moisture. When the shell 603 is squeezed, the limit rod 604 extends out of the fixed box 401, and the spring 1 605 is compressed. When the push rod 602 moves to the right, the spring 1 605 is opened, and the limit rod 604 returns to the inside of the fixed box 401 again to realize the sponge cover 601 opening to absorb water, thereby preventing water from dripping onto the upper pressing roller 206 and the lower pressing roller 209 to cause rust, which is conducive to applying silicone oil in the next process.

[0037] Finally, the interior of the oil tank 701 is filled with silicone oil, and the oil-absorbing cotton rope 705 can absorb the silicone oil inside it into the interior of the two sponge brushes 704. After the electromagnetic wire body 504 is cleaned of water, it is extended to the outside of the fixed box 401 and will pass through the two sponge brushes 704. The silicone oil on the sponge brushes 704 will be smeared on the electromagnetic wire body 504, which can reduce the friction damage caused by the electromagnetic wire during the straightening process. When the push rod 602 moves to the left, the limit rod 604 is squeezed out of the outer wall of the fixed box 401. At this time, the limit rod 604 can be squeezed with the rack 706 on the outer wall of the support column 707, and the spring two 708 is opened. Since the rack 706 is engaged with the gear four 703, when the rack 706 is driven to move back and forth horizontally, the two gears four 703 are rotated relative to each other, and the two sponge brushes 704 can be changed to contact the electromagnetic wire body 504 in a cycle at different positions, which is conducive to the uniform application of silicone oil and always ensures that there is silicone oil on the sponge brush 704.
