The wire drawing piece 306 is fixedly mounted on the upper surface of the main mounting frame 1 , and a lower guide wheel 307 is provided on one side of the wire drawing piece 306 close to the winding roller 308 .

[0023] During operation, the aluminum wire in the present invention is led out through the drawing piece 306 in the upper drawing unit 3 and wound onto the winding roller 308, and then the aluminum wire is led out through the side limiting wheel 305 at the upper end of the winding roller 308 and enters between the limiting rings 303, and then the aluminum wire passes through the upper end of the upper guide wheel 302, and then passes through the lower side of the lower guide wheel 307 and enters the drawing piece 306 of this drawing unit 3.

[0024] As a further solution of the present invention, the lower movable part 19 is sleeved on the lower end of the winding roller 308, and a plurality of sets of embedding grooves 1902 are provided on the outer side of the upper end of the lower movable part 19. A movable baffle 1901 is rotatably installed on the upper end of the embedding groove 1902 through a torsion spring. A lower limit plate 304 is fixedly installed on the upper surface of the main mounting frame 1 at a position corresponding to the winding roller 308. A limit rod 16 is fixedly installed on the lower surface of the lower limit plate 304. The limit rod 16 is slidably connected to the lower end of the lower movable part 19.

The lower limit frame 15 is fixedly connected to the main mounting frame 1, and a reset spring 1903 is fixedly installed on the lower limit frame 15 and the lower surface of the lower movable part 19.

[0025] During operation, in a natural state, the lower movable member 19 is located between the lower limit plates 304, and the winding roller 308 rotates so that the aluminum wire is wound around the surface of the lower movable member 19 (such as Fig.10 As shown on the left side, the movable baffle 1901 can only rotate downward when it is in a horizontal state. When the upper movable member 21 presses down to apply pressure to the lower movable member 19, it can squeeze the movable baffle 1901, so that the movable baffle 1901 rotates into the embedded groove 1902, and the upper movable member 21 pushes the lower movable member 19 to move downward, so that the upper movable member 21 moves between the aluminum wires wrapped around the outer side of the lower movable member 19 (such as Fig.10 As shown in the middle, the upper movable member 21 starts to move upward due to the disappearance of pressure, and the squeezing effect of the upper movable member 21 on the lower movable member 19 disappears. The movable baffle 1901 returns to a horizontal state under the action of the torsion spring, and the lower movable member 19 moves upward to move the aluminum wire and the upper movable member 21 upward synchronously, so that the aluminum wire wound on the lower movable member 19 moves up to above the movable baffle 1901 (as shown in the middle). Fig.10As shown on the right side), avoid the aluminum wire from accumulating at the bottom of the lower movable part 19.

[0026] As a further solution of the present invention, the upper movable part 21 is also sleeved on the outside of the winding roller 308 and its lower surface is in contact with the upper surface of the lower movable part 19. A positioning rod 20 is fixedly installed on the upper end of the upper movable part 21, and an upper connecting plate 8 is fixedly installed on the upper end of the positioning rod 20. A connecting rod 9 is fixedly installed on the lower surface of the upper connecting plate 8 at a position corresponding to the position between the wire drawing units 3, and the lower end of the connecting rod 9 extends into the main mounting frame 1.

[0027] During operation, the upper connecting plate 8 can drive multiple groups of upper movable parts 21 to move downward synchronously, so that multiple groups of wire drawing units 3 can operate synchronously.

[0028] As a further solution of the present invention, the transmission assembly includes: A lower connecting plate 13, the lower connecting plate 13 is fixedly mounted on the lower surface of the connecting rod 9, and an inner compression spring 14 is arranged between the upper surface of the lower connecting plate 13 and the main mounting frame 1; The swing member 22 is arranged at both ends of the lower connecting plate 13 and is rotatably connected to the main mounting frame 1. The middle position of the swing member 22 is the rotation axis and the two ends are respectively provided with a counterweight end 2201 and a curved plate 2202. The counterweight end 2201 can drive the swing member 22 to rotate under the action of gravity, and after the rotation, the lower connecting plate 13 can be pressed down by the counterweight end 2201. The curved plate 2202 is a curved arc plate with an opening downward. The upper surface of the curved plate 2202 is in contact with a telescopic rod 2203. The upper end of the telescopic rod 2203 is rotatably connected to the fixed seat 18. The fixed seat 18 is fixedly installed in the main mounting frame 1.

The toggle rod 23 is fixedly mounted on the upper end of the side connecting plate 7 , and the rotation of the toggle rod 23 can drive the telescopic rod 2203 to rotate away from the curved plate 2202 .

[0029] During operation, the side connecting plate 7 of the present invention rotates to drive the toggle rod 23 to rotate. When the toggle rod 23 rotates to the telescopic rod 2203 position, the toggle rod 23 makes the telescopic rod 2203 move away from the curved plate 2202, and the interference effect of the telescopic rod 2203 on the swing member 22 disappears. At this time, the swing member 22 rotates to the left under the action of the counterweight end 2201, so that the counterweight end 2201 is pressed on the surface of the lower connecting plate 13, thereby causing the lower connecting plate 13 to move downward. The lower connecting plate 13 moves downward and drives the upper connecting plate 8 downward through the connecting rod 9. The upper connecting plate 8 moves downward and drives the upper movable member 21 downward through the positioning rod 20. When the toggle rod 23 rotates away from the telescopic rod 2203, the telescopic rod 2203 automatically rotates back to the vertical state, and the lower end of the telescopic rod 2203 again contacts the upper surface of the curved plate 2202. The swing member 22 rotates to make the counterweight end 2201 move up and away from the lower connecting plate 13, so that the upper movable member 19 automatically moves up under the inner compression spring 14.

[0030] A limiting groove 201 is provided on the upper surface of the winding drum 2, and the limiting grooves 201 are distributed in a circle on the winding drum 2. A rotating rod 203 is rotatably installed in the limiting groove 201, and a support frame 4 is threadedly connected to the rotating rod 203.

A gear box 11 is arranged in the main mounting frame 1, and the gears in the gear box 11 can drive multiple groups of winding rollers 308 to rotate.

[0031] During operation, the aluminum wire is wound on the surface of the support frame 4, and the diameter of the circular ring formed by the support frame 4 can be adjusted by rotating the lower bevel gear 204. The lower bevel gear 204 rotates forward, driving the upper bevel gear 202 to rotate reversely, so that through the interaction between the rotating rod 203 and the support frame 4, the distance between the support frames 4 is increased, the winding diameter is increased, and the reverse rotation of the lower bevel gear 204 makes the support frames 4 approach each other.

[0032] A wire drawing process for large-size enameled round aluminum wires for power transformers, the specific steps of the wire drawing process are as follows: Step 1: The aluminum wire is wound through the wire drawing unit 3 in sequence, and the end of the aluminum wire is wound and fixed on the surface of the support frame 4 on the winding reel 2; Step 2: The aluminum wire is continuously pulled from the wire drawing unit 3 to the winding reel 2 by rotating the winding reel 2 to complete the drawing of the aluminum wire. The drawn aluminum wire is wound around the bottom of the support frame 4. Step 3: When the winding reel 2 rotates to wind up the aluminum wire, the support frame 4 is uniformly lowered through the interaction between the threaded member 6 and the lower positioning plate 5, so that the aluminum wire can be evenly wound around the surface of the support frame 4; Step 4: Every time the winding disk 2 rotates one circle, the telescopic rod 2203 can be pushed to rotate by the toggle rod 23, and the interference effect of the telescopic rod 2203 on the swing member 22 disappears. The swing member 22 rotates to make the counterweight end 2201 descend, and the downward movement of the counterweight end 2201 drives the upper movable member 21 to move downward; Step 5: The upper movable member 21 moves downward to squeeze the lower movable member 19, so that the lower end of the upper movable member 21 moves to the position of the lower limit plate 304, and then the aluminum wire wound at the lower end of the winding roller 308 is pushed to the outer side of the upper movable member 21 by moving the lower movable member 19 upward.
