AI Technical Summary
In existing high-speed continuous drawing equipment for prestressed steel wire, the intense friction between the steel wire and the drawing die leads to increased energy consumption, accelerated die wear, and affects the surface quality of the steel wire. At the same time, friction and deformation heat cause the die temperature to rise, which in turn accelerates die wear.
The system employs a lubricant spraying system and a coolant spraying system. The friction wheel drives the gear to rotate, so that the lubricant can be evenly covered on the surface of the steel wire. The telescopic mechanism enables intermittent spraying. Combined with the oscillation of the cooling water jacket, the coolant coverage area is increased, energy consumption is reduced, and mold wear is slowed down.
It effectively reduced energy consumption, slowed down the wear of drawing dies, improved the surface quality of steel wire and production continuity, and reduced the cost of using the equipment.

Description
Technical Field
[0001] This invention relates to the field of steel wire drawing equipment technology, and in particular to a high-speed continuous drawing equipment for prestressed steel wire. Background Technology
[0002] The high-speed continuous drawing equipment for prestressed steel wire is an intelligent production line designed for the efficient processing of metal wires. Through the synergy of a multi-level dynamic tension control system and high-frequency pulse lubrication technology, it achieves precise deformation control of the steel wire during high-speed movement. The equipment integrates an adaptive speed matching algorithm, which can automatically adjust the drawing rate and annealing process parameters according to material characteristics, ensuring continuous production and product consistency. Its core advantage lies in breaking through the capacity bottleneck of traditional processes, significantly improving wire strength and surface quality, while reducing energy consumption and material loss. This equipment is widely used in high-end manufacturing fields such as bridge cables and prestressed concrete components, effectively meeting the demand for large-scale, high-quality supply of high-performance steel wire materials in infrastructure construction, and promoting the upgrading of the metal products processing industry towards intelligence and green development.
[0003] In actual use, existing devices generate severe friction between the steel wire and the drawing die, which not only increases energy consumption but also leads to accelerated die wear and affects the surface quality of the steel wire. Furthermore, under the influence of friction and deformation heat, the temperature of the drawing die rises rapidly, causing the die material to soften and accelerating die wear. Therefore, a high-speed continuous drawing device for prestressed steel wire is proposed. Summary of the Invention
[0004] The purpose of this invention is to solve the problems in the prior art, where there is severe friction between the steel wire and the drawing die, which not only increases energy consumption but also leads to accelerated die wear and affects the surface quality of the steel wire. Furthermore, under the action of friction and deformation heat, the temperature of the drawing die will rise rapidly, resulting in softening of the die material and accelerating die wear. Therefore, this invention proposes a high-speed continuous drawing device for prestressed steel wire.
[0005] To achieve the above objectives, the present invention adopts the following technical solution:
[0006] A high-speed continuous drawing device for prestressed steel wire includes a transmission housing. A drawing die is fixedly connected to the upper part of the transmission housing. A grinding wheel is fixedly connected to both sides of the drawing die. A reciprocating housing is fixedly connected inside the drawing die. A friction wheel is provided at the lower part of the reciprocating housing. A third transmission wheel is fixedly connected to the friction wheel. A second transmission belt is driven by the third transmission wheel. A fourth transmission wheel is driven by the second transmission belt. A third gear is fixedly connected to the fourth transmission wheel. The third gear is meshed with a gear groove. The gear groove is slidably connected to the reciprocating housing. A nozzle is fixedly connected to the lower part of the gear groove. A lubricating fluid pipe is fixedly connected to the upper part of the nozzle. A telescopic mechanism is provided on one side of the nozzle. A movable baffle is provided on one side of the telescopic mechanism.
[0007] During the wire drawing process, the wire moves rapidly inside the drawing die. The friction caused by this movement drives the friction wheel to rotate, which in turn drives the third gear. This rotation of the third gear causes the meshing gear groove to reciprocate, which in turn drives the nozzle at the bottom to reciprocate along the wire's path, ensuring the lubricant evenly covers the wire surface. During lubricant spraying, a telescopic mechanism drives a movable baffle to extend and retract within the nozzle, resulting in intermittent lubricant spraying. Only half of the third gear surface has teeth, while the gear groove has teeth of the same module on both the upper and lower sides. The rotation of the third gear drives the gear groove to reciprocate. The transmission housing uses a high-strength aluminum alloy frame and stainless steel panel composite structure. The top is bolted to the drawing die assembly. The drawing die contains a diamond-coated core. The die nozzle uses a double-layer ceramic nozzle design: an outer zirconium oxide wear-resistant layer and an inner tungsten carbide flow-guiding layer. O-rings on both sides allow for modular replacement.
[0008] The above technical solution further includes:
[0009] The telescopic mechanism includes a third motor located on one side of the nozzle, and a telescopic component is provided at the output end of the third motor.
[0010] The telescopic assembly includes a second eccentric shaft at the output end of a third motor, a rotating plate rotatably connected to the second eccentric shaft, and a movable baffle rotatably connected to the rotating plate. The movable baffle is slidably connected to the nozzle, and when the movable baffle is fully inserted into the nozzle, it can seal the inside of the nozzle, thereby preventing the lubricant from flowing out.
[0011] The transmission housing is equipped with a first motor at both ends, and the output end of the first motor is equipped with a pay-off drum and a take-up drum. The pay-off drum uses a magnetic powder brake to achieve constant tension control, and the take-up drum is equipped with a torque motor to achieve adaptive take-up of the winding diameter.
[0012] The transmission housing contains a second motor, and the output end of the second motor is equipped with a wheel. There are multiple wheels, which are respectively arranged on the moving path of the steel wire. The wheels have grooves inside, and the steel wire can be driven within the grooves. The second motor is driven by a planetary reducer. The surface of the wheel is machined with polyurethane grooves, and a pressure sensor is installed at the bottom of the groove to monitor the contact force of the steel wire in real time.
[0013] The rotating wheel principle states that a first transmission wheel is fixedly connected to one side of the second motor, the first transmission wheel is driven by a first transmission belt, the first transmission belt is driven by a second transmission wheel, and the second transmission wheel is fixedly connected to a first gear.
[0014] The first gear is rotatably connected to the swing housing, and the swing housing is fixedly connected to the upper part of the transmission housing.
[0015] The first gear is meshed with a second gear, the second gear is fixedly connected to a first eccentric shaft, the first eccentric shaft is slidably connected to a swinging component, and the lower part of the swinging component is rotatably connected to a swinging housing.
[0016] The bottom of the swing component is fixedly connected to a connector, and the connector is fixedly connected to a cooling water jacket. The cooling water jacket adopts a split copper alloy structure, with a spiral turbulent flow channel inside. A vortex flow meter is installed at the water inlet, and a temperature sensor is configured at the water outlet to form a closed-loop control.
[0017] The present invention has the following beneficial effects:
[0018] 1. In this invention, the steel wire moves at high speed inside the drawing die during the drawing process. The movement of the drawing die drives the friction wheel to rotate, which in turn drives the third gear to rotate. The rotation of the third gear drives the meshing gear groove to move back and forth, thereby driving the nozzle to move back and forth along the steel wire's movement path inside the drawing die. This effectively improves the lubricant coverage. Furthermore, by injecting lubricant into the steel wire inside the drawing die, the surface of the steel wire can be covered with lubricant before friction occurs, further reducing energy consumption and slowing down the wear of the drawing die. During the lubricant injection process, the telescopic mechanism can drive the movable baffle to move back and forth inside the nozzle, thus allowing the lubricant to be injected intermittently. This effectively saves the amount of lubricant injected while ensuring the lubrication and cooling effect, thereby reducing the cost of using the device.
[0019] 2. In this invention, the steel wire can be limited by the rotating wheel connected by rotation during the wire drawing process. The rotation of the wheel can drive the first gear to rotate, and the rotation of the first gear can drive the connecting piece to swing back and forth, thereby driving the cooling water jacket to swing back and forth, thus effectively increasing the spray area of the coolant and improving the coverage effect of the coolant during the wire drawing process, ensuring that the steel wire is cooled in time during the drawing process.

[0027] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.
[0028] Example 1
[0029] like Figures 1-6As shown, a high-speed continuous drawing device for prestressed steel wire includes a transmission housing 1. A drawing die 7 is fixedly connected to the upper part of the transmission housing 1. Abrasive openings 18 are fixedly connected to both sides of the drawing die 7. A reciprocating housing 19 is fixedly connected inside the drawing die 7. A friction wheel 21 is provided at the lower part of the reciprocating housing 19. A third transmission wheel 24 is fixedly connected to the friction wheel 21. A second transmission belt 25 is driven by the third transmission wheel 24. A fourth transmission wheel 26 is driven by the second transmission belt 25. A third gear 27 is fixedly connected to the fourth transmission wheel 26. A gear groove 23 is meshed with the third gear 27. The gear groove 23 is slidably connected to the reciprocating housing 19. A nozzle 22 is fixedly connected to the lower part of the gear groove 23. A lubricating fluid pipe 20 is fixedly connected to the upper part of the nozzle 22. A telescopic mechanism is provided on one side of the nozzle 22. A movable baffle 31 is provided on one side of the telescopic mechanism.
[0030] During the wire drawing process, the wire moves rapidly inside the drawing die 7. As the wire moves, friction causes the friction wheel 21 to rotate, which in turn drives the third gear 27 to rotate. The rotation of the third gear 27 drives the meshing gear groove 23 to move back and forth, which in turn drives the nozzle 22 at the bottom to move back and forth along the wire's movement path, so that the lubricant evenly covers the surface of the wire. During the lubricant spraying process, the telescopic mechanism drives the movable baffle 31 to move back and forth inside the nozzle 22, so that the lubricant is sprayed intermittently. Only half of the surface of the third gear 27 is provided with teeth, while the upper and lower sides of the gear groove 23 are provided with teeth of the same module. When the third gear 27 rotates, it can drive the gear groove 23 to move back and forth.
[0031] The telescopic mechanism includes a third motor 28 located on one side of the nozzle 22. The output end of the third motor 28 is provided with a telescopic component. The telescopic component includes a second eccentric shaft 29 located at the output end of the third motor 28. The second eccentric shaft 29 is rotatably connected to a rotating plate 30. The rotating plate 30 is rotatably connected to a movable baffle 31. The movable baffle 31 is slidably connected to the nozzle 22. When the movable baffle 31 is fully inserted into the nozzle 22, it can seal the inside of the nozzle 22, thereby preventing the lubricant from flowing out.
[0032] In this embodiment, the steel wire moves at high speed inside the drawing die 7 during the drawing process. During the movement of the drawing die 7, the friction wheel 21 can be driven to rotate under the action of friction. The rotation of the friction wheel 21 drives the fixedly connected third transmission wheel 24 to rotate. The rotation of the third transmission wheel 24 drives the fourth transmission wheel 26, which is connected by the second transmission belt 25, to rotate. The rotation of the fourth transmission wheel 26 drives the fixedly connected third gear 27 to rotate. The rotation of the third gear 27 drives the meshing gear groove 23 to move back and forth, thereby driving the nozzle 22 to move back and forth along the steel wire movement path inside the drawing die 7. Lubricating fluid is delivered to the nozzle 22 through the lubricating fluid pipe 20, which can make the lubricating fluid evenly cover the surface of the steel wire, effectively improving the lubricating fluid coverage effect. Moreover, by injecting lubricating fluid into the steel wire inside the drawing die 7, the surface of the steel wire can be covered with lubricating fluid before friction occurs, further reducing energy consumption and slowing down the wear of the drawing die 7.
[0033] During the lubricant dispensing process, the third motor 28 drives the second eccentric shaft 29 to rotate. The rotation of the second eccentric shaft 29 drives the rotating plate 30 to rotate. The rotation of the rotating plate 30 drives the movable baffle 31 to move back and forth inside the nozzle 22, thereby enabling the lubricant to be dispensed intermittently. This effectively saves the amount of lubricant dispensed while ensuring the lubrication and cooling effect, thus reducing the cost of using the device.
[0034] Example 2
[0035] like Figures 1-6 As shown, a first motor 2 is provided at both ends of the transmission housing 1. A wire feeding drum 3 and a wire taking drum 4 are provided at the output end of the first motor 2. A second motor 11 is provided inside the transmission housing 1. A rotating wheel 5 is provided at the output end of the second motor 11. There are multiple rotating wheels 5, which are respectively set on the moving path of the steel wire. The rotating wheel 5 has a groove inside, and the steel wire can be driven in the groove. A first transmission wheel 8 is fixedly connected to one side of the second motor 11. The first transmission wheel 8 is driven by a first transmission belt 9. The first transmission belt 9 is driven by a second transmission wheel 10. The second transmission wheel 10 is fixedly connected to a first gear 12.
[0036] The first gear 12 is rotatably connected to the swing housing 6. The swing housing 6 is fixedly connected to the upper part of the transmission housing 1. The first gear 12 is meshed with the second gear 13. The second gear 13 is fixedly connected to the first eccentric shaft 14. The first eccentric shaft 14 is slidably connected to the swing member 15. The swing housing 6 is rotatably connected to the lower part of the swing member 15. The bottom of the swing member 15 is fixedly connected to the connector 16. The connector 16 is fixedly connected to the cooling water jacket 17.
[0037] In this embodiment, during the wire drawing process, the second motor 11 drives the rotating wheel 5 to rotate, thereby limiting the wire. The rotation of the rotating wheel 5 synchronously drives the fixedly connected first transmission wheel 8 to rotate, which in turn drives the first transmission belt 9 to rotate. The rotation of the first transmission belt 9 drives the second transmission wheel 10 to rotate, which in turn drives the fixedly connected first gear 12 to rotate. The rotation of the first gear 12 drives the meshing second gear 13 to rotate, which in turn drives the fixedly connected first eccentric shaft 14 to rotate. The rotation of the first eccentric shaft 14 drives the slidingly connected swing member 15 to reciprocate. The reciprocating movement of the swing member 15 drives the fixedly connected connector 16 to swing back and forth, which in turn drives the cooling water jacket 17 to swing back and forth, thereby effectively increasing the spray area of the coolant and improving the coolant coverage during the wire drawing process, ensuring that the wire is cooled in time during the drawing process.
