[0029] See also Figures 1 to 8 The present invention provides a technical solution: a stretching device for producing ultra-fine electromagnetic wires, such as Figure 1 As shown, it includes a base 1, a first rotating shaft 2, a second rotating shaft 3 and a third rotating shaft 4. The first rotating shaft 2 and the second rotating shaft 3 are respectively arranged on the left and right sides of the upper surface of the base 1, and the third rotating shaft 4 is arranged in the middle of the upper surface of the base 1 near the rear end. The rear ends of the first rotating shaft 2, the second rotating shaft 3 and the third rotating shaft 4 are fixedly connected to the output end of the external driving device. A bearing seat 7 is fixedly installed on the upper surface of the base 1 corresponding to the front ends of the first rotating shaft 2, the second rotating shaft 3 and the third rotating shaft 4, and the ends of the first rotating shaft 2, the second rotating shaft 3 and the third rotating shaft 4 are rotatably installed inside the bearing seat 7. A wire roller 5 is fixedly installed on the outer surfaces of the first rotating shaft 2, the second rotating shaft 3 and the third rotating shaft 4, and the outer surfaces of the first rotating shaft 2, the second rotating shaft 3 and the third rotating shaft 4 are located at A threaded ring 6 is screwed on the front end of the wire roller 5, a clamping hole 8 is provided on the front side of the bearing seat 7, and a dust cover 9 is clamped on the front end of the bearing seat 7. A polishing device 11 is fixedly installed on the upper surface of the base 1 between the first rotating shaft 2 and the second rotating shaft 3, and a U-shaped groove 12 is provided on the upper surface of the polishing device 11, and the left and right ends of the U-shaped groove 12 are open. The interior of the polishing device 11 is located at the front and rear sides of the lower end of the U-shaped groove 12 and has circular holes 13, and an electric push rod 14 is fixedly installed inside the circular hole 13, the end of the electric push rod 14 leads to the inside of the U-shaped groove 12, and a fastening ring 15 is movably installed at the end of the electric push rod 14, a spring 16 is welded on the inner wall of the fastening ring 15, and a polishing layer 17 is bonded to the end of the spring 16.

[0030] Furthermore, the outer surfaces of the first rotating shaft 2, the second rotating shaft 3 and the third rotating shaft 4 are welded with protruding teeth 201, and the protruding teeth 201 are evenly arranged in a ring shape on the outer surfaces of the first rotating shaft 2, the second rotating shaft 3 and the third rotating shaft 4, and the first rotating shaft 2, the second rotating shaft 3 and the third rotating shaft 4 have the same diameter.

[0031] Furthermore, the wire roller 5 includes a hollow column 501, a retaining ring 502, a groove 503 and a short shaft 504. Retaining rings 502 are integrally formed at both ends of the hollow column 501. A groove 503 is formed in the inner wall of the hollow column 501, and the groove 503 leads to the outer side surface of the retaining ring 502. A short shaft 504 is welded to the outer surface of one set of the retaining rings 502 near the periphery of the hollow column 501, and there is a gap between the short shaft 504 and the hollow column 501. One end of the magnet wire is wound around the outer surface of the short shaft 504 for several turns for fixation. When wire drawing is performed, wire drawing is carried out through the rotational speed difference of the three wire rollers 5.

[0032] Furthermore, there are multiple sets of grooves 503, which are evenly arranged in a ring shape on the inner wall of the hollow column 501. The shape and size of the grooves 503 are the same as those of the convex teeth 201, and the convex teeth 201 are located inside the grooves 503. Through the engagement of the convex teeth 201 and the grooves 503, the first rotating shaft 2, the second rotating shaft 3 and the third rotating shaft 4 drive the wire roller 5 to rotate.

[0033] Furthermore, four sets of card holes 8 are formed in the front side surface of each bearing seat 7, and the card holes 8 are evenly arranged in a ring shape on the front side surface of the bearing seat 7. Round shafts 10 are welded to the inner wall of the dust cover 9 corresponding to the positions of the card holes 8, and the round shafts 10 are inserted into the interior of the card holes 8. The outer surface of the round shaft 10 is coated with an anti-slip pad. The dust cover 9 is fixedly connected to the bearing seat 7 through the round shafts 10. The dust cover 9 covers the outside of the three wire rollers 5. The dust cover 9 shields the magnet wire that has been drawn and polished, preventing dust or impurities from falling on the surface of the magnet wire. Two handles are installed on the outer surface of the dust cover 9, which facilitates the disassembly of the dust cover 9.

[0034] Furthermore, the fastening ring 15 is composed of two arc-shaped plates. A U-shaped through groove is formed on the upper surface of the end of the electric push rod 14. The fastening ring 15 is located in the U-shaped through groove, and a shaft hole is formed in the front side surface of the fastening ring 15. A绞轴18 passes through the shaft hole, and both ends of the绞轴18 are rotatably connected to the inner wall of the U-shaped through groove. According to the gradually decreasing diameter of the magnet wire during wire drawing, the electric push rod 14 extends and gradually approaches each other, so that the diameter of the fastening device composed of the two fastening rings 15 becomes smaller.

[0035] Furthermore, a torsion spring is sleeved on the outer surface of the绞轴18 inside the shaft hole, and both ends of the torsion spring are fixedly connected to the two arc-shaped plates respectively. The two arc-shaped plates are fixedly formed into the fastening ring 15 through the torsion spring, and the fastening ring 15 is hinged to the electric push rod 14 through the绞轴18. The torsion spring forms an inward extrusion force between the two arc-shaped plates. The spring 16 is compressed, and the spring 16 gives a rebound force to the polishing layer 17, making it in close contact with the surface of the magnet wire and polishing the surface smooth during the movement of the magnet wire.

[0036] It should be noted that there is an unclear "绞轴" in the original text. It is recommended to check and clarify this term for a more accurate translation. Here, it is directly translated as "绞轴" for the time being.Furthermore, the electromagnetic wire passes through the wire roller 5 on the outer surface of the second rotating shaft 3, the wire roller 5 on the outer surface of the first rotating shaft 2 and the wire roller 5 on the outer surface of the third rotating shaft 4 in sequence, and the rotation speed of the third rotating shaft 4 is greater than the rotation speed of the second rotating shaft 3, and the rotation speed of the second rotating shaft 3 is greater than the rotation speed of the first rotating shaft 2.

[0037] Working principle: install the wire roller 5 with the electromagnetic wire wound on the outside on the outer surface of the second rotating shaft 3, the convex tooth 201 is meshed with the groove 503, and the threaded ring 6 is tightened to fix the wire roller 5. Pass one end of the electromagnetic wire through the polishing device 11 and then bypass the wire roller 5 on the outer surface of the second rotating shaft 2. The coil can be wound several times here. The end of the electromagnetic wire bypasses the wire roller 5 on the outer surface of the third rotating shaft 4, and is fixed after being wound several times on the outer surface of the short shaft 504. A bearing seat 7 is set at the front end of the three sets of rotating shafts, align the round shaft 10 inside the dust cover 9 with the clamping hole 8 on the front side of the bearing seat 7, and insert the round shaft 10 into the clamping hole 8. The anti-skid pad on the outer surface of the round shaft 10 increases the friction between the clamping hole 8 and the round shaft 10. The dust cover 9 is installed on the outside of the three groups of wire rollers 5, and the driving devices corresponding to the first rotating shaft 2, the second rotating shaft 3 and the third rotating shaft 4 are started, and three groups of different rotation speeds are set, wherein the rotation speed of the first rotating shaft 2 is greater than the rotation speed of the second rotating shaft 3, and less than the rotation speed of the third rotating shaft 4. Due to the different rotation speeds of the shafts, the rotation speeds of the wire rollers 5 are also different. The electromagnetic wire is stretched during the winding process, and the stretching force is always kept consistent. When the electromagnetic wire passes through the U-shaped groove 12 in the polishing device 11, it passes through the center of the fastening ring 15. The torsion spring inside the fastening ring 15 gives the spring 16 inward pressure, so that the spring 16 gives pressure to the polishing layer 17. The polishing layer 17 contacts with the outer surface of the electromagnetic wire. During the pulling process of the electromagnetic wire, the polishing layer 17 polishes its surface smoothly.

[0038] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
