Description

Technical Field

[0001] The present invention relates to the technical field of wire drawing equipment, and specifically to a wire drawing equipment and process for large-sized enameled round aluminum wire suitable for power transformers. Background Art

[0002] The pulley type wire drawing machine is a common aluminum wire drawing equipment. During the processing, the winding equipment of the aluminum wire rotates, causing the aluminum wire to pass through multiple groups of pulley traction equipment to gradually complete the wire drawing of the aluminum wire.

[0003] Most of the winding equipment of the above-mentioned pulley type wire drawing machine winds the aluminum wire by rotation, causing the aluminum wire to wind around the surface of the winding equipment. However, during the winding process, as the length of the drawn aluminum wire increases, the aluminum wire begins to repeatedly wind around the surface of the winding equipment. This not only makes the wound aluminum wires cross and disordered and difficult to disassemble quickly, but also when the aluminum wire winds around the surface of the winding equipment, the winding diameter on the surface of the winding equipment will gradually increase during the winding of the latter section of the aluminum wire (as shown on the left side), which means that when the winding equipment rotates by the same angle, the traction length of the latter section of the aluminum wire after wire drawing is greater than that of the former section, and the wire drawing time of the latter section of the aluminum wire between the pulley wire drawing machines is relatively shorter, which may cause insufficient wire drawing time for the latter section of the aluminum wire and damage to the processing quality. Figure 11 As shown on the left side, this makes the traction length of the latter section of the aluminum wire after wire drawing greater than that of the former section when the winding equipment rotates by the same angle, and the wire drawing time of the latter section of the aluminum wire between the pulley wire drawing machines is relatively shorter, which may cause insufficient wire drawing time for the latter section of the aluminum wire and damage to the processing quality. Summary of the Invention

[0004] The technical problem of the present invention is to provide a wire drawing equipment and process for large-sized enameled round aluminum wire suitable for power transformers, so that the aluminum wire can be evenly and staggeredly wound by the rotating and descending winding disc, ensuring the flat surface of the wound aluminum wire and making the traction speeds of the former and latter sections of the wire drawing process consistent.

[0005] To achieve the above object, the present invention provides the following technical solution: A wire drawing equipment for large-sized enameled round aluminum wire suitable for power transformers, including a main mounting frame and an aluminum wire. A winding disc and multiple groups of equally spaced wire drawing units are arranged on the main mounting frame. The aluminum wire passes through multiple groups of wire drawing units in sequence and then winds around the winding disc. An adjusting component is arranged between the winding disc and the wire drawing units, and the adjusting component includes:

[0006] A moving component, which is arranged at the lower end of the winding disc and can drive the winding disc to rotate while driving the winding disc to move downward at a uniform speed;

[0007] A pushing component, which includes a lower movable part and an upper movable part. Winding rollers are arranged in each wire drawing unit. The lower movable part and the upper movable part are slidably connected outside the winding rollers. The upper movable part is arranged at the upper end of the lower movable part and can push the lower movable part to slide downward. The aluminum wire can wind around the surfaces of the upper movable part and the lower movable part;

[0008] The transmission assembly is arranged between the upper movable part and the winding disc, and the transmission assembly can regularly press down the lower movable part when the winding disc rotates.

[0009] As a further solution of the present invention, the moving assembly includes a side connecting plate, a threaded member and a lower positioning plate. The lower positioning plate is arranged at the lower end of the main mounting frame. The lower positioning plate is threadedly connected with the threaded member. The upper end of the side connecting plate is rotatably connected to the lower surface of the winding disc, and the lower end is fixedly connected with the threaded member. A gear ring is fixedly installed at the upper end of the side connecting plate. A driving gear is rotatably connected to the lower surface of the winding disc. The driving gear meshes with the gear ring.

[0010] As a further solution of the present invention, the wire drawing unit includes:

[0011] A winding roller is rotatably connected to the main mounting frame and its lower end extends into the main mounting frame. A side limiting wheel is rotatably arranged on one side of the upper end of the winding roller;

[0012] An upper guide wheel is arranged above the winding roller. An upper mounting frame is fixedly installed on the upper surface of the main mounting frame. A plurality of upper traction frames are fixedly installed on the upper mounting frame. A limiting ring is fixedly installed on the upper traction frame. The axis of the limiting ring coincides with that of the winding roller. The upper guide wheel is rotatably connected between the upper traction frames;

[0013] A wire drawing piece is fixedly installed on the upper surface of the main mounting frame. A lower guide wheel is arranged on one side of the wire drawing piece close to the winding roller.

[0014] As a further solution of the present invention, the lower movable part is sleeved on the lower end of the winding roller. A plurality of embedding grooves are opened on the outer side of the upper end of the lower movable part. An activity baffle is rotatably installed at the upper end of the embedding groove through a torsion spring. A lower limiting plate is fixedly installed on the upper surface of the main mounting frame corresponding to the position of the winding roller. A limiting rod is fixedly installed on the lower surface of the lower limiting plate. The limiting rod is slidably connected with the lower end of the lower movable part. The lower end of the limiting rod is embedded into the main mounting frame and a lower limiting frame is fixedly installed. The lower limiting frame is fixedly connected with the main mounting frame. A reset spring is fixedly installed between the lower limiting frame and the lower surface of the lower movable part.

[0015] As a further solution of the present invention, the upper movable part is also sleeved outside the winding roller and its lower surface abuts against the upper surface of the lower movable part. A positioning rod is fixedly installed at the upper end of the upper movable part. An upper connecting plate is fixedly installed at the upper end of the positioning rod. A connecting rod is fixedly installed on the lower surface of the upper connecting plate corresponding to the position between the wire drawing units. The lower end of the connecting rod extends into the main mounting frame.

[0016] As a further solution of the present invention, the transmission assembly includes:

[0017] A lower connecting plate, which is fixedly installed on the lower surface of the connecting rod. An inner compression spring is arranged between the upper surface of the lower connecting plate and the main mounting frame;

[0018] A swinging member, which is arranged at both ends of the lower connecting plate and is rotatably connected to the main mounting frame. The middle position of the swinging member is the rotation axis, and a counterweight end and a curved plate are respectively arranged at both ends. The counterweight end can drive the swinging member to rotate under the action of gravity, and after rotation, it can press down the lower connecting plate through the counterweight end. The curved plate is a curved arc plate with an opening downward. The upper surface of the curved plate abuts against a telescopic rod, and the upper end of the telescopic rod is rotatably connected to a fixed seat. The fixed seat is fixedly installed in the main mounting frame. When the telescopic rod abuts against the upper surface of the curved plate, the position of the curved plate can be lower than that of the counterweight end;

[0019] A dial rod, which is fixedly installed at the upper end of the side connecting plate. The rotation of the dial rod can drive the telescopic rod to rotate away from the curved plate.

[0020] As a further solution of the present invention, a limiting groove is formed on the upper surface of the winding disc. The limiting grooves are circumferentially distributed on the winding disc. Rotating rods are rotatably installed in the limiting grooves. Support frames are threadedly connected to the rotating rods. One end of each rotating rod is fixedly installed with an upper bevel gear. A lower bevel gear is rotatably installed on the lower surface of the winding disc. The lower bevel gear meshes with the upper bevel gear. A gear box is arranged in the main mounting frame, and the gears in the gear box can drive multiple winding rollers to rotate.

[0021] A wire drawing process suitable for large-sized enameled round aluminum wire of power transformers. The specific steps of this wire drawing process are as follows:

[0022] Step 1: The aluminum wire is sequentially wound through the wire drawing unit, and the end of the aluminum wire is wound and fixed on the surface of the support frame on the winding disc;

[0023] Step 2: The winding disc rotates to continuously pull the aluminum wire through the wire drawing unit and wind it onto the winding disc to complete the wire drawing of the aluminum wire. The drawn aluminum wire is wound at the bottom of the support frame;

[0024] Step 3: When the winding disc rotates to wind the aluminum wire, the support frame descends uniformly under the interaction of the threaded member and the lower positioning plate, so that the aluminum wire can be evenly wound on the surface of the support frame;

[0025] Step 4: Every time the winding disc rotates one circle, it can push the telescopic rod to rotate through the dial rod. The abutting action of the telescopic rod on the swinging member disappears. The swinging member rotates to make the counterweight end descend, and the downward movement of the counterweight end drives the upper movable member to descend;

[0026] Step Five: The upper movable part moves downward to press the lower movable part, so that the lower end of the upper movable part moves to the position of the lower limit plate, and then the lower movable part moves upward to push the aluminum wire wound around the lower end of the winding roller to the outer side position of the upper movable part.

[0027] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0028] While the reel rotates to wind the aluminum wire, the winding reel moves downward at a constant speed under the action of the moving component, so that the aluminum wire can be spirally wound on the winding reel, avoiding the repeated winding of the aluminum wire at the same position, making the aluminum wire wound on the support frame stagger from each other, ensuring that the length of the aluminum wire that can be wound in one turn of the winding reel in the front section and the rear section of the aluminum wire drawing process remains the same, so that the aluminum wire drawing processing time in the front section and the rear section is kept the same, ensuring the quality of the aluminum wire processing, and at the same time avoiding the trouble that the wound aluminum wires are intertwined with each other and difficult to unload;

[0029] In the present invention, through the transmission component, the winding reel can move downward periodically during the downward movement process. Through the reciprocating movement of the upper movable part and the lower movable part, the aluminum wire wound on the surface of the lower movable part can be pushed to the outer side of the upper movable part at the upper end, so as to be able to periodically clear the aluminum wire wound on the surface of the lower movable part, avoiding the problem that the aluminum wire may accumulate at the bottom of the winding roller due to the too fast introduction of the aluminum wire into the wire drawing unit, and further avoiding the possibility that the continuous flow of the aluminum wire is blocked due to the entanglement of the aluminum wires with each other.

DETAILED DESCRIPTION

[0044] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0045] See also Figures 1 - 12The present invention provides a technical solution: a large-size enameled round aluminum wire drawing device suitable for power transformers, comprising a main mounting frame 1 and an aluminum wire, the main mounting frame 1 is provided with a winding drum 2 and a plurality of equally spaced drawing units 3, the aluminum wire is wound on the winding drum 2 after passing through the plurality of drawing units 3 in sequence, an adjusting component is provided between the winding drum 2 and the drawing unit 3, and the adjusting component comprises:

[0046] A moving assembly, which is arranged at the lower end of the winding drum 2, and can drive the winding drum 2 to move downward at a uniform speed while driving the winding drum 2 to rotate;

[0047] The pusher assembly includes a lower movable member 19 and an upper movable member 21. A winding roller 308 is provided in each wire drawing unit 3. The lower movable member 19 and the upper movable member 21 are slidably connected to the outside of the winding roller 308. The upper movable member 21 is provided at the upper end of the lower movable member 19 and can push the lower movable member 19 to slide downward. The aluminum wire can be wound on the surface of the upper movable member 21 and the lower movable member 19.

[0048] The transmission assembly is arranged between the upper movable member 21 and the winding disk 2 , and the transmission assembly can regularly press down the lower movable member 19 when the winding disk 2 rotates.

[0049] During operation, the aluminum wire in the present invention passes through the wire drawing unit 3 in sequence and is then fixed on the winding drum 2. The winding drum 2 is rotated to pull the aluminum wire toward the winding drum 2. During the pulling process, the wire drawing unit 3 gradually completes the wire drawing of the aluminum wire, so that the aluminum wire gradually becomes thinner, and the thinned aluminum wire is wound on the winding drum 2. While the winding drum 2 rotates to wind the aluminum wire, the winding drum 2 moves downward at a uniform speed under the action of the moving component, so that the aluminum wire can be spirally wound on the winding drum 2, avoiding repeated winding of the aluminum wire at the same position, so that the aluminum wires wound on the support frame 4 can be staggered with each other (such as Figure 11 As shown on the right side), the length of aluminum wire that can be wound up by the winding drum 2 in the front and rear sections of the aluminum wire drawing process is kept consistent after one rotation, so that the length of the aluminum wire drawing process in the front and rear sections is kept consistent, ensuring the quality of the aluminum wire processing, while also avoiding the trouble of the wound aluminum wires being entangled with each other and difficult to unload. In the present invention, the transmission component is used to enable the winding drum 2 to move downward periodically during the downward movement, and the upper movable member 21 and the lower movable member 19 are moved up and down reciprocatingly to push the aluminum wire wound on the surface of the lower movable member 19 to the surface of the upper movable member 21 (as shown in FIG. Figure 10 As shown), the aluminum wire wrapped around the surface of the lower movable part 19 can be cleared at regular intervals to avoid the problem of the aluminum wire being introduced into the wire drawing unit 3 too quickly and possibly accumulating at the bottom of the winding roller 308, thereby avoiding the possibility of the aluminum wire being entangled with each other and hindering the continuous flow of the aluminum wire.

[0050] As a further solution of the present invention, the moving component includes a side connecting plate 7, a threaded member 6 and a lower positioning plate 5. The lower positioning plate 5 is arranged at the lower end of the main mounting frame 1. The lower positioning plate 5 is threadedly connected with the threaded member 6. The upper end of the side connecting plate 7 is rotatably connected to the lower surface of the winding disc 2, and the lower end is fixedly connected with the threaded member 6. A gear ring 12 is fixedly installed at the upper end of the side connecting plate 7. A driving gear 17 is rotatably connected to the lower surface of the winding disc 2. The driving gear 17 meshes with the gear ring 12.

[0051] During operation, the motor drives the driving gear 17 to rotate. The rotation of the driving gear 17 interacts with the gear ring 12, thereby driving the side connecting plate 7 to drive the threaded member 6 to rotate. The rotation of the threaded member 6 interacts with the lower positioning plate 5, thereby driving the threaded member 6 to move downward. The downward movement of the threaded member 6 drives the winding disc 2 to gradually move downward while rotating.

[0052] As a further solution of the present invention, the wire drawing unit 3 includes:

[0053] A winding roller 308, which is rotatably connected to the main mounting frame 1 and the lower end extends into the main mounting frame 1. A side limiting wheel 305 is rotatably arranged on one side of the upper end of the winding roller 308;

[0054] An upper guide wheel 302, which is arranged above the winding roller 308. An upper mounting frame 10 is fixedly installed on the upper surface of the main mounting frame 1. A plurality of upper traction frames 301 are fixedly installed on the upper mounting frame 10. A limiting ring 303 is fixedly installed on the upper traction frame 301. The axis of the limiting ring 303 coincides with that of the winding roller 308. The upper guide wheel 302 is rotatably connected between the upper traction frames 301;

[0055] A wire drawing piece 306, which is fixedly installed on the upper surface of the main mounting frame 1. A lower guide wheel 307 is arranged on one side of the wire drawing piece 306 close to the winding roller 308.

[0056] During operation, in the present invention, the aluminum wire is led out by the wire drawing piece 306 in the upper wire drawing unit 3 and wound around the winding roller 308. 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. 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 wire drawing piece 306 of this wire drawing unit 3.

[0057] As a further solution of the present invention, the lower movable member 19 is sleeved on the lower end of the winding roller 308. A plurality of sets of embedding grooves 1902 are provided on the outer side of the upper end of the lower movable member 19. An activity baffle 1901 is rotatably installed at 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 corresponding to the position of 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 member 19. The lower end of the limit rod 16 is embedded in the main mounting frame 1 and a lower limit frame 15 is fixedly installed. The lower limit frame 15 is fixedly connected to the main mounting frame 1. A return spring 1903 is fixedly installed between the lower limit frame 15 and the lower surface of the lower movable member 19.

[0058] During operation, in the natural state, the lower movable member 19 is located between the lower limit plates 304. When the winding roller 308 rotates, the aluminum wire is wound on the surface of the lower movable member 19 (as shown on the left side), and the activity baffle 1901 can only rotate downward when it is in the horizontal state. When the upper movable member 21 presses down to apply pressure to the lower movable member 19, the activity baffle 1901 can be squeezed, so that the activity baffle 1901 rotates into the embedding groove 1902. 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 wound outside the lower movable member 19 (as shown in the middle), and then the upper movable member 21 starts to move upward when the pressure disappears. Then the squeezing effect of the upper movable member 21 on the lower movable member 19 disappears. The activity baffle 1901 returns to the horizontal state under the action of the torsion spring. The lower movable member 19 moves upward to synchronously move the aluminum wire and the upper movable member 21 upward, so that the aluminum wire wound on the lower movable member 19 moves upward above the activity baffle 1901 (as shown on the right side), avoiding the accumulation of aluminum wire at the bottom of the lower movable member 19. Figure 10 During operation, in the natural state, the lower movable member 19 is located between the lower limit plates 304. When the winding roller 308 rotates, the aluminum wire is wound on the surface of the lower movable member 19 (as shown on the left side), and the activity baffle 1901 can only rotate downward when it is in the horizontal state. When the upper movable member 21 presses down to apply pressure to the lower movable member 19, the activity baffle 1901 can be squeezed, so that the activity baffle 1901 rotates into the embedding groove 1902. 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 wound outside the lower movable member 19 (as shown in the middle), and then the upper movable member 21 starts to move upward when the pressure disappears. Then the squeezing effect of the upper movable member 21 on the lower movable member 19 disappears. The activity baffle 1901 returns to the horizontal state under the action of the torsion spring. The lower movable member 19 moves upward to synchronously move the aluminum wire and the upper movable member 21 upward, so that the aluminum wire wound on the lower movable member 19 moves upward above the activity baffle 1901 (as shown on the right side), avoiding the accumulation of aluminum wire at the bottom of the lower movable member 19. Figure 10 During operation, in the natural state, the lower movable member 19 is located between the lower limit plates 304. When the winding roller 308 rotates, the aluminum wire is wound on the surface of the lower movable member 19 (as shown on the left side), and the activity baffle 1901 can only rotate downward when it is in the horizontal state. When the upper movable member 21 presses down to apply pressure to the lower movable member 19, the activity baffle 1901 can be squeezed, so that the activity baffle 1901 rotates into the embedding groove 1902. 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 wound outside the lower movable member 19 (as shown in the middle), and then the upper movable member 21 starts to move upward when the pressure disappears. Then the squeezing effect of the upper movable member 21 on the lower movable member 19 disappears. The activity baffle 1901 returns to the horizontal state under the action of the torsion spring. The lower movable member 19 moves upward to synchronously move the aluminum wire and the upper movable member 21 upward, so that the aluminum wire wound on the lower movable member 19 moves upward above the activity baffle 1901 (as shown on the right side), avoiding the accumulation of aluminum wire at the bottom of the lower movable member 19. Figure 10 During operation, in the natural state, the lower movable member 19 is located between the lower limit plates 304. When the winding roller 308 rotates, the aluminum wire is wound on the surface of the lower movable member 19 (as shown on the left side), and the activity baffle 1901 can only rotate downward when it is in the horizontal state. When the upper movable member 21 presses down to apply pressure to the lower movable member 19, the activity baffle 1901 can be squeezed, so that the activity baffle 1901 rotates into the embedding groove 1902. 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 wound outside the lower movable member 19 (as shown in the middle), and then the upper movable member 21 starts to move upward when the pressure disappears. Then the squeezing effect of the upper movable member 21 on the lower movable member 19 disappears. The activity baffle 1901 returns to the horizontal state under the action of the torsion spring. The lower movable member 19 moves upward to synchronously move the aluminum wire and the upper movable member 21 upward, so that the aluminum wire wound on the lower movable member 19 moves upward above the activity baffle 1901 (as shown on the right side), avoiding the accumulation of aluminum wire at the bottom of the lower movable member 19.

[0059] As a further solution of the present invention, the upper movable member 21 is also sleeved outside the winding roller 308 and its lower surface abuts against the upper surface of the lower movable member 19. A positioning rod 20 is fixedly installed at the upper end of the upper movable member 21. An upper connecting plate 8 is fixedly installed at 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 corresponding to the position between the wire drawing units 3. The lower end of the connecting rod 9 extends into the main mounting frame 1.

[0060] During operation, the upper connecting plate 8 can drive a plurality of upper movable members 21 to move downward synchronously, so that a plurality of wire drawing units 3 can operate synchronously.

[0061] As a further solution of the present invention, the transmission assembly includes:

[0062] A lower connecting plate 13, the lower connecting plate 13 is fixedly installed on the lower surface of the connecting rod 9. An internal compression spring 14 is arranged between the upper surface of the lower connecting plate 13 and the main mounting frame 1;

[0063] The swing member 22 is provided 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 a counterweight end 2201 and a curved plate 2202 are respectively provided at both ends. The counterweight end 2201 can drive the swing member 22 to rotate under the action of gravity, and after rotation, it can press down the lower connecting plate 13 through the counterweight end 2201. The curved plate 2202 is a curved arc plate with an opening downward, and a telescopic rod 2203 abuts against the upper surface of the curved plate 2202. The upper end of the telescopic rod 2203 is rotatably connected to the fixed seat 18, and the fixed seat 18 is fixedly installed in the main mounting frame 1. When the telescopic rod 2203 abuts against the upper surface of the curved plate 2202, the position of the curved plate 2202 can be lower than that of the counterweight end 2201;

[0064] The toggle rod 23 is fixedly installed at the upper end of the side connecting plate 7. The rotation of the toggle rod 23 can drive the telescopic rod 2203 to rotate away from the curved plate 2202.

[0065] During operation, in the present invention, the side connecting plate 7 rotates to drive the toggle rod 23 to rotate. When the toggle rod 23 rotates to the position of the telescopic rod 2203, the toggle rod 23 causes the telescopic rod 2203 to move away from the curved plate 2202, and the abutting action of the telescopic rod 2203 on the swing member 22 disappears. At this time, under the action of the counterweight end 2201, the swing member 22 rotates to the left, so that the counterweight end 2201 presses on the surface of the lower connecting plate 13, thereby causing the lower connecting plate 13 to move downward. The downward movement of the lower connecting plate 13 drives the upper connecting plate 8 to move downward through the connecting rod 9, and the downward movement of the upper connecting plate 8 drives the upper movable member 21 to move downward through the positioning rod 20. When the toggle rod 23 rotates away from the telescopic rod 2203, the telescopic rod 2203 automatically rotates and resets to restore the vertical state, and the lower end of the telescopic rod 2203 abuts against the upper surface of the curved plate 2202 again. The rotation of the swing member 22 causes the counterweight end 2201 to move upward away from the lower connecting plate 13, so that the upper movable member 19 automatically moves upward under the action of the inner compression spring 14.

[0066] A limiting groove 201 is formed on the upper surface of the winding disc 2. The limiting grooves 201 are circumferentially distributed on the winding disc 2. Rotating rods 203 are rotatably installed in the limiting grooves 201. Support frames 4 are threadedly connected to the rotating rods 203. One end of the rotating rod 203 is fixedly installed with an upper bevel gear 202. A lower bevel gear 204 is rotatably installed on the lower surface of the winding disc 2.

[0067] 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.

[0068] 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:

[0069] 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;

[0070] 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.

[0071] 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;

[0072] 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;

[0073] 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.
