Description

Technical Field

[0001] This invention relates to the field of tungsten wire production and drawing technology, specifically to a wire drawing device for tungsten wire production. Background Technology

[0002] A tungsten filament drawing machine is a specialized piece of equipment used to process tungsten rods or billets into fine filaments through a drawing process. Its core principle is to gradually reduce the diameter of the tungsten material through multiple drawing and annealing processes, ultimately obtaining tungsten filaments of the desired specifications. Tungsten filaments are widely used in the lighting industry (such as incandescent lamp filaments), the electronics industry (such as vacuum tube components), medical equipment (such as X-ray tube targets), and heating elements for high-temperature furnaces due to their high melting point (3422°C), high strength, good electrical conductivity, and corrosion resistance. Most existing tungsten wire drawing devices use a fixed guide wheel structure to guide and tension the tungsten wire. This type of structure can only be manually adjusted by the operator before the wire drawing operation starts, according to the specifications of the tungsten wire. It is inconvenient to readjust it during the operation. When the tungsten wire is continuously drawn and wound, the stress state changes constantly, and the tension fluctuates frequently. When the tension increases suddenly, it is very easy for the tungsten wire to break. The broken tungsten wire deviates from the predetermined path and is easy to get stuck in the gap between the guide wheel and the frame, causing wire jamming failure, which affects the continuity of production and production efficiency. Summary of the Invention

[0006] Furthermore, the tensioning component includes a power unit, the surface of which is fixedly connected to the inner wall of the housing, a central rod fixedly connected to the output end of the power unit, the surface of which is fixedly connected to the center of the adjusting frame, a slant frame connected to the bottom of the limiting frame, a through pipe connected to the lower surface of the slant frame, an anti-overflow hole at the end of the limiting frame, and through holes at both ends of the limiting frame, with two rotating rods rotatably connected to the inner wall of the through holes.

[0007] Furthermore, the output end of the power unit passes through the limiting frame and extends into the interior of the limiting frame, the end of the limiting frame extends to the outer end of the housing, the overflow hole is located inside the housing, and a valve pipe is provided at the bottom of the inclined frame, and the valve pipe is located inside the housing.

[0008] Furthermore, there are two inclined frames, which are connected by a through pipe and are located below the grooved wheel. There are two grooved wheels and two rollers, with the two rollers located at the ends of the two grooved wheels that are close to each other. The adjustment frame is inclined.

[0009] Furthermore, the anti-jamming component includes a support plate, the end of which is fixedly connected to the end of the housing, and a driver is mounted on the top of the support plate, the output end of which is fixedly connected to the bottom of the disc.

[0010] Furthermore, the support plate is located below the limiting frame, the cylindrical slide rod is located at the end of the limiting frame and corresponds to the through hole, and there is a distance between the cylindrical slide rod and the end of the limiting frame.

[0011] Furthermore, the adjusting component includes a threaded rod, the end of which is fixedly connected to the output end of the drive device, the surface of which is threadedly connected to the inner wall of the movable frame, a positioning rod rotatably connected to the inner wall of the anti-detachment frame, a positioning hole being provided at the end of the anti-detachment frame, and an anti-jamming rod rotatably connected to the inner wall of the positioning hole.

[0012] Furthermore, the end of the mounting rod is fixedly connected to the surface of the fixing plate. The mounting rod and the threaded rod are symmetrically arranged through the movable frame. The positioning rod is located below the anti-detachment frame. The top of the positioning rod contacts the bottom of the tungsten wire. There are four anti-jamming rotating rods. The four anti-jamming rotating rods are arranged in two groups, and each group has two rods. The two groups of anti-jamming rotating rods are symmetrically arranged with the positioning rod as the center.

[0013] The present invention has the following beneficial effects: This invention is equipped with a circulating cooling system consisting of a water tank, a water pump, water pipes, a spray pipe, a bend, and an overflow hole. The water pump delivers coolant from the water tank to the water pipes, and the spray pipes directly spray the intermediate die head and the internal tungsten wire to cool them down. At the same time, the bend sends coolant into the limiting frame to cool the tungsten wire in the tensioning section simultaneously. Excess coolant in the tank flows back to the water tank through the overflow hole. In conjunction with the anti-overflow hole, the inclined frame, and the through pipe on the limiting frame to drain the accumulated liquid, this invention not only achieves the recycling of coolant and reduces resource waste, but also continuously removes the high frictional temperature generated during the tungsten wire drawing process, preventing the tungsten wire from becoming brittle, deformed, or experiencing performance degradation due to high temperatures.

[0014] The tensioning component of this invention consists of a limiting frame, a power unit, an adjusting frame, rollers, grooved wheels, and a rotating rod. It can adjust the tension of the tungsten wire in real time. The power unit drives the central rod to rotate the inclined adjusting frame, causing the two sets of grooved wheels to shift synchronously, squeezing or releasing the tungsten wire. This allows for flexible adjustment of the wire drawing tension. When the tension is insufficient, the tungsten wire is tightened to ensure the accuracy of wire drawing. When the tension is too high, it is appropriately loosened to prevent the tungsten wire from breaking due to tension. At the same time, the rotating rod in the through hole isolates and protects the passing tungsten wire, reducing direct friction between the tungsten wire and the hard inner wall of the limiting frame, further reducing the occurrence of tungsten wire wear and breakage.

[0015] The anti-jamming component of this invention includes a support plate, a driver, a disc, and a cylindrical slide rod. Tungsten wire is wound around the surface of the cylindrical slide rod and travels through it. The driver drives the disc and the cylindrical slide rod to rotate synchronously with the tungsten wire conveying direction. On the one hand, it provides support and guidance for the tungsten wire in the bending and turning sections, buffering the pulling force caused by the change of the tungsten wire angle. On the other hand, the position limit of the cylindrical slide rod, combined with the gap reserved between it and the end of the limit frame, prevents the tungsten wire from getting stuck in the gap of the box and the limit frame during the displacement and turning process, ensuring the smooth tungsten wire conveying line.

[0016] The adjustment component of this invention relies on a mounting rod, a threaded rod, a movable frame, an anti-detachment frame, a positioning rod, and an anti-jamming rod to complete the lateral displacement adjustment. The driving device drives the threaded rod to rotate, drives the movable frame to slide smoothly along the mounting rod, and then drives the anti-detachment frame to move laterally. The positioning rod supports the tungsten wire, and with the help of two sets of symmetrically arranged anti-jamming rods, it provides all-round protection. This not only promotes the tungsten wire to be evenly spread on the surface of the winding device, preventing the tungsten wire from piling up and overlapping, and making the winding roll neatly arranged, but also avoids hard friction between the tungsten wire and the anti-detachment frame and the inner wall of the positioning hole.

[0020] A water tank 3 is provided at one end of the housing 1. A drain valve is provided on the surface of the water tank 3. A water pump 12 is installed on the surface of the water tank 3. The inlet of the water pump 12 is connected to the lower surface of the water tank 3. A water pipe 13 is connected to the outlet of the water pump 12. A spray pipe 14 is connected to the surface of the water pipe 13. A bend pipe 15 is connected to the surface of the water pipe 13. A fixing plate 9 is fixedly connected to the end of the housing 1 away from the water tank 3. A drive device 11 is fixedly connected to the surface of the fixing plate 9. A winding device 10 is installed on the surface of the fixing plate 9. An unwinding device 7 is installed inside the housing 1. The inner wall of the body 1 is provided with an overflow hole 8. The body 1 is connected to the water tank 3 through the overflow hole 8. The top of the body 1 is hinged with an inspection door 2. The end of the water pipe 13 away from the water pump 12 extends into the interior of the body 1. The spray pipe 14 is located above the intermediate mold head 6. When the water pump 12 starts to work, it will transfer the coolant in the water tank 3 to the water pipe 13. The spray pipe 14 will spray the coolant on the intermediate mold head 6 to cool the tungsten wire 5. The coolant in the body 1 will flow back to the water tank 3 through the overflow hole 8 to avoid the overflow of too much coolant.

[0021] The tensioning component 16 includes a power unit 21. The surface of the power unit 21 is fixedly connected to the inner wall of the housing 1. A center rod 26 is fixedly connected to the output end of the power unit 21. The surface of the center rod 26 is fixedly connected to the center of the adjusting frame 22. The bottom of the limiting frame 20 is connected to an inclined frame 25. The lower surface of the inclined frame 25 is connected to a through pipe 27. An anti-overflow hole 29 is provided at the end of the limiting frame 20. Through holes 24 are provided at both ends of the limiting frame 20. Two rotating rods 30 are rotatably connected to the inner wall of the through holes 24.

[0022] The output end of the power unit 21 passes through the limiting frame 20 and extends into the interior of the limiting frame 20. The end of the limiting frame 20 extends to the outer end of the housing 1. The overflow hole 29 is located inside the housing 1. A valve pipe is provided at the bottom of the inclined frame 25, and the valve pipe is located inside the housing 1. When the tungsten wire 5 enters the interior of the limiting frame 20, the worker needs to pass the tungsten wire 5 through the two grooved wheels 28 in sequence. (The positional relationship between the tungsten wire 5 and the grooved wheels 28 is shown in the figure.) Figure 6 The tungsten wire 5 is limited by the grooved wheel 28. Two rotating rods 30 are set inside the through hole 24, and the tungsten wire 5 is located at the end of the two rotating rods 30 that are close to each other. The rotating rods 30 protect the tungsten wire and prevent it from breaking due to friction with the limiting frame 20. When the tension of the tungsten wire 5 needs to be adjusted, the power device 21 is started to drive the adjusting frame 22 to rotate. The grooved wheel 28 located in the housing 1 will move downward, and the grooved wheel 28 located at the outer end of the housing 1 will tilt upward. At this time, the two grooved wheels 28 will squeeze the tungsten wire 5 to increase the tension of the tungsten wire 5 during the wire drawing operation. When the tension of the tungsten wire 5 is high, the power device 21 is started to drive the adjusting frame 22 to start to reverse. At this time, the grooved wheel 28 will loosen with the movement of the adjusting frame 22 and the tungsten wire 5 to prevent the tungsten wire 5 from breaking due to excessive tension.

[0023] There are two inclined frames 25, which are connected by a through pipe 27. The inclined frames 25 are located below the grooved wheel 28. There are two grooved wheels 28 and two rollers 23. The two rollers 23 are located at the ends of the two grooved wheels 28 that are close to each other. The adjustment frame 22 is inclined.

[0024] The anti-jamming component 17 includes a support plate 40, the end of which is fixedly connected to the end of the housing 1, and a driver 42 is mounted on the top of the support plate 40. The output end of the driver 42 is fixedly connected to the bottom of the disc 41.

[0025] The support plate 40 is located below the limiting frame 20, and the cylindrical slide rod 43 is located at the end of the limiting frame 20 and corresponds to the through hole 24. The cylindrical slide rod 43 is provided with a distance from the end of the limiting frame 20.

[0026] The adjusting component 18 includes a threaded rod 51, the end of which is fixedly connected to the output end of the drive device 11. The surface of the threaded rod 51 is threadedly connected to the inner wall of the movable frame 52. A positioning rod 55 is rotatably connected to the inner wall of the anti-detachment frame 53. A positioning hole 56 is provided at the end of the anti-detachment frame 53, and an anti-jamming rod 54 is rotatably connected to the inner wall of the positioning hole 56. The movable frame 52 moves with the threaded rod 51 under the limit of the mounting rod 50. The tungsten wire 5 is located inside the anti-detachment frame 53 and contacts the positioning rod 55. When the movable frame 52 moves, it pushes the tungsten wire 5 to move through the anti-detachment frame 53. When the winding device 10 winds the tungsten wire 5... During winding, the anti-detachment frame 53 pushes the tungsten wire 5 to move, so that the tungsten wire 5 can be laid flat on the surface of the winding device 10, avoiding the tungsten wire 5 from gathering together during winding. An anti-jamming rotating rod 54 is provided at the end of the anti-detachment frame 53. The anti-jamming rotating rod 54 is used to protect the tungsten wire 5, preventing the tungsten wire 5 from rubbing against the surface of the anti-detachment frame 53 due to the change in angle when the anti-detachment frame 53 moves. When the anti-detachment frame 53 moves, it will pull the tungsten wire 5 to change the angle at the cylindrical slide rod 43. The cylindrical slide rod 43 is used to limit the tungsten wire 5, preventing the tungsten wire 5 from getting stuck in the box 1 or the limiting frame 20 when the anti-detachment frame 53 moves.

[0027] The end of the mounting rod 50 is fixedly connected to the surface of the fixing plate 9. The mounting rod 50 and the threaded rod 51 are symmetrically arranged through the movable frame 52. The positioning rod 55 is located below the anti-detachment frame 53. The top of the positioning rod 55 contacts the bottom of the tungsten wire 5. There are four anti-jamming rotating rods 54. The four anti-jamming rotating rods 54 are set in two groups, and each group has two rods. The two groups of anti-jamming rotating rods 54 are symmetrically arranged with the positioning rod 55 as the center.

[0028] In use, after the worker opens the inspection door 2, the tungsten wire 5 is installed sequentially in the drawing die frame 4 and the intermediate die head 6. The frame containing the tungsten wire is placed on the surface of the unwinding device 7, and the winding frame is placed on the surface of the winding device 10. When the drawing die frame 4 and the intermediate die head 6 begin operation, the unwinding device 7 rotates to release the tungsten wire 5, preventing it from breaking due to excessive tension. The winding device 10 then winds up the drawn tungsten wire 5. When the water pump 12 starts operating, it pumps water... The coolant in box 3 is transferred to water pipe 13. Spray pipe 14 sprays the coolant onto the intermediate die head 6 to cool the tungsten wire 5. The coolant in box 1 flows back to water tank 3 through overflow hole 8 to prevent overflow. Before the winding device 10, the worker needs to pass the tungsten wire 5 through the limiting frame 20. When the tungsten wire 5 enters the limiting frame 20, the worker needs to pass the tungsten wire 5 through the two grooved wheels 28 in sequence. (The positional relationship between the tungsten wire 5 and the grooved wheels 28 is shown in the figure.) Figure 6The tungsten wire 5 is limited by the grooved wheel 28. Two rotating rods 30 are installed inside the through hole 24, with the tungsten wire 5 located at the ends of the two rotating rods 30 close to each other. The rotating rods 30 protect the tungsten wire, preventing it from breaking due to friction with the limiting frame 20. When the tension of the tungsten wire 5 needs to be adjusted, the power device 21 is activated to rotate the adjusting frame 22. The grooved wheel 28 in the housing 1 moves downward, while the grooved wheel 28 at the outer end of the housing 1 tilts upward. At this time, the two grooved wheels 28 compress the tungsten wire 5, increasing its tension during the wire drawing process. The tension of the tungsten wire 5 is adjusted according to the specified tension. The starting power unit 21 drives the adjusting frame 22 to start reversing. At this time, the grooved wheel 28 will loosen with the movement of the adjusting frame 22 and the tungsten wire 5, so as to avoid the tungsten wire 5 from breaking due to excessive tension. The adjusting frame 22 is used to adaptively adjust the tension of the tungsten wire 5, thereby improving the stability of the tungsten wire 5 during the wire drawing operation. Meanwhile, the bending pipe 15 will spray coolant into the limiting frame 20, and use the coolant to cool the tungsten wire 5 in the limiting frame 20. An overflow hole 29 is provided at the end of the limiting frame 20. The coolant in the limiting frame 20 will be discharged into the interior of the housing 1 through the overflow hole 29, so as to avoid the coolant in the limiting frame 20 from overflowing and being wasted.

[0029] After the tungsten wire 5 passes through the limiting frame 20, it needs to be wound around the surface of the cylindrical slide bar 43. At this time, the driver 42 is activated to drive the disc 41 and the cylindrical slide bar 43 to rotate in the direction of movement of the tungsten wire 5. The cylindrical slide bar 43 supports and limits the tungsten wire 5. When the driving device 11 drives the threaded rod 51 to rotate, the moving frame 52 will move with the threaded rod 51 under the limitation of the mounting rod 50. The tungsten wire 5 is located inside the anti-detachment frame 53 and contacts the positioning rod 55. When the moving frame 52 moves, it will push the tungsten wire 5 to move through the anti-detachment frame 53. When the winding device 10 winds the tungsten wire 5, the anti-detachment frame 53 will push the tungsten wire 5 to move. The movement allows the tungsten wire 5 to be laid flat on the surface of the winding device 10, preventing the tungsten wire 5 from gathering together during winding. An anti-jamming rod 54 is provided at the end of the anti-detachment frame 53 to protect the tungsten wire 5 and prevent the tungsten wire 5 from rubbing against the surface of the anti-detachment frame 53 due to angle changes when the anti-detachment frame 53 moves. When the anti-detachment frame 53 moves, it will pull the tungsten wire 5 to change its angle at the cylindrical slide rod 43. The cylindrical slide rod 43 is used to limit the tungsten wire 5 and prevent the tungsten wire 5 from getting stuck in the box 1 or the limiting frame 20 when the anti-detachment frame 53 moves, thus improving the stability of the tungsten wire 5 during wire drawing operations.
