Technical Field
[0001] This invention relates to the field of steel wire production technology, and in particular to an automatic wiping device for a hot-dip galvanizing production line for steel wire. Background Technology
[0002] Hot-dip galvanizing of steel wire is a common process for metal surface anti-corrosion treatment. Its production process typically includes pickling, fluxing, drying, zinc immersion, and wiping / cooling. Among these, the wiping process is crucial in determining the amount of zinc on the steel wire and the surface quality of the coating. After the steel wire is drawn from the zinc bath, excess zinc liquid needs to be removed from its surface using a wiping device, and the thickness and uniformity of the coating must be controlled.
[0003] In the prior art, for example, Chinese Patent Publication No. CN201169613Y discloses a wiping device for hot-dip galvanizing steel wire. This device uses an electromagnetic induction coil to generate an alternating magnetic field around the steel wire, inducing a current on the zinc layer surface. The interaction between the alternating magnetic field and the induced current generates a Lorentz force, which presses the zinc liquid around the zinc layer surface, causing the zinc liquid to flow back, thereby reducing the thickness of the galvanized layer. However, this prior art only addresses the problem of zinc layer thickness control and does not address the suppression of vibration during steel wire operation. Another example is Chinese Patent Publication No. CN205046185U, which discloses a vibration damping device for galvanized steel strip. This device uses several electromagnetic induction devices staggered on both sides of the strip to effectively reduce the vibration of the steel strip through electromagnetic repulsion. However, this prior art mainly addresses the vibration control of the strip and does not address the double-layer limiting structure of the steel wire during the hot-dip galvanizing process.
[0004] However, existing hot-dip galvanizing production lines for steel wire mainly have the following technical problems in actual operation:
[0005] Excessive vibration during wire movement leads to coating misalignment: During high-speed operation, especially when vertically drawn from the zinc bath, the wire is highly susceptible to vibration due to fluctuations in traction force or fluid resistance. Existing production lines often lack effective, multi-stage stabilization devices, or rely solely on simple mechanical stops. These stops come into contact with the coating on the wire surface, causing the coating to thin upon contact and affecting production quality.
[0006] Meanwhile, the shaking will cause the steel wire to become unstable when passing through the wiping area, resulting in uneven force around the steel wire. This will eventually lead to uneven galvanized layer thickness (causing eccentricity) or bamboo-like ripples on the surface, which will seriously affect product quality.
[0007] Therefore, developing an automatic wiping device for hot-dip galvanizing production lines that can effectively reduce wire vibration (especially by using a double-layer anti-vibration system combining contact and non-contact methods), reduce guide wear, and facilitate quick adjustment, disassembly, and maintenance is a technical problem that urgently needs to be solved in this field. Summary of the Invention
[0008] To achieve the above objectives, the present invention employs the following technical solution: an automatic wiping device for a hot-dip galvanizing production line for steel wire, comprising: a primary limiting component, disposed at the zinc pot outlet, for contact-type limiting of the drawn steel wire; a secondary limiting component, disposed downstream of the primary limiting component, for non-contact-type limiting of the steel wire; and a wiping component, disposed downstream of the secondary limiting component, for wiping the steel wire.
[0009] In a preferred embodiment, the primary limiting component includes a rear plate, a zinc pot, a spring, a limiting telescopic rod, and clamping semicircular blocks. A zinc pot is fixedly installed at the bottom of the rear plate. Springs are fixedly installed on opposite sides of the inner wall of the zinc pot, and limiting telescopic rods are fixedly installed on opposite sides of the inner wall of the zinc pot. Clamping semicircular blocks are fixedly installed at opposite ends of the two limiting telescopic rods and the two springs. A steel wire passes through the interior of the two clamping semicircular blocks to limit their movement and reduce vibration during movement. A cooling mechanism is also provided at the top of the rear plate to cool the steel wire after it passes through the guide roller, accelerating the solidification of the zinc liquid. A thickness control device is also provided at the top of the rear plate to monitor the coating thickness on the surface of the steel wire in real time and adjust the pressure of the wiping component according to the thickness.
[0010] In a preferred embodiment, a guide assembly is fixedly installed on the top of the rear plate. The guide assembly includes a guide roller and a fixing cylinder. The fixing cylinder is installed on the top of the rear plate, and a limit telescopic rod is fixedly installed on the top of the rear plate.
[0011] In a preferred embodiment, a second spring is fixedly installed on the top of the rear plate, and a movable cylinder is fixedly installed on one end of the second spring and the limiting telescopic rod, with a block installed on the outer surface of the movable cylinder.
[0012] In a preferred embodiment, two grooves are provided on the inner walls of both the movable cylinder and the fixed cylinder, and the guide roller is movably embedded inside the fixed cylinder and the second spring.
[0013] In a preferred embodiment, the secondary limiting component includes two vertical bars, multiple limiting rods and a second magnet; two vertical bars are fixedly installed on the top of the rear plate, multiple limiting rods are fixedly installed on the opposite side of the two vertical bars, and a second magnet is fixedly installed on the outer surface of the multiple limiting rods.
[0014] In a preferred embodiment, a slider is slidably connected to the outer surface of a plurality of the limiting rods, and an electric push rod is fixedly installed on one side of one of the vertical bars, with the output end of the electric push rod fixedly installed on one side of the slider.
[0015] In a preferred embodiment, a first magnet is fixedly installed at the bottom of the slider. The first magnet and the second magnet are arranged opposite each other on both sides of the steel wire. The steel wire passes between the first magnet and the second magnet to limit its movement and further reduce vibration. The wiping assembly includes multiple U-shaped blocks. Multiple U-shaped blocks are arranged on the top of the rear plate. The multiple U-shaped blocks are evenly divided into two groups. One group of U-shaped blocks has a threaded rod embedded inside, and the other group of U-shaped blocks has a short rod movably embedded inside. The bottom ends of the multiple threaded rods are rotatably mounted with a locking block through a bearing. The multiple U-shaped blocks are fixedly installed on the top of the locking block.
[0016] In a preferred embodiment, a long strip is fixedly installed on one side of another set of U-shaped blocks, a threaded rod is threadedly embedded in the top of the rear plate, a limiting rod is movably embedded in the top of the rear plate, and the threaded rod is installed on one side of the long strip through a bearing.
[0017] In a preferred embodiment, the limiting rod is fixedly installed on one side of the long strip, and a wiping ring is detachably installed inside the multiple U-shaped blocks. The multiple wiping rings are on opposite sides, and multiple locking holes are opened on the outer surface of the multiple U-shaped blocks.
[0018] Compared with the prior art, the advantages and positive effects of the present invention are as follows:
[0019] 1. In this embodiment of the invention, the steel wire is first fed out from inside the zinc pot. The steel wire passes through the inside of two clamping semicircular blocks and is then fed out from inside the zinc pot. At this time, the two clamping semicircular blocks clamp and limit the steel wire under the cooperation of the limiting telescopic rod and the spring, which can reduce the vibration of the steel wire when it is fed out from inside the zinc pot. At this time, the steel wire passes over the upper surface of the guide roller. The guide roller is mounted on the rear plate through bearings and can rotate with the movement of the steel wire, reducing the wear of the steel wire and preventing the zinc on the surface of the steel wire from being worn away. The guide roller guides and limits the steel wire, preventing the steel wire from deviating at an angle after being fed out, so that the steel wire is in a straight line. When the steel wire passes over the opposing surfaces of the second magnet and the first magnet, the first magnet and the second magnet attract or repel each other, which reduces the vibration of the steel wire when passing through. By setting a double-layer anti-vibration structure, the subsequent wiping effect is better, the vibration is reduced, and the wiping thickness is more uniform. The steel wire passes through the middle of two wiping rings, which merge into a circle to wipe the zinc off the surface of the steel wire before proceeding to the next process.
[0020] 2. In this embodiment of the invention, an electric push rod is activated by an external power source to push the slider to slide on the outer surface of the limiting rod one, thereby moving the first magnet at the bottom. The distance between the first magnet and the second magnet can be adjusted to accommodate steel wires of different thicknesses. This allows for limiting the movement of steel wires of varying thicknesses, preventing vibration. The second magnet and the first magnet are positioned so that the wire is limited without contact, further reducing vibration. By rotating the threaded rod two, the long strip moves back and forth under the limitation of the limiting rod two, thereby moving one set of wiping rings. This facilitates placing the steel wire between the two wiping rings. Simultaneously, rotating the threaded rod one, under the limitation of the short rod, moves the bottom locking block. The bottom of the locking block has two locking rods that engage with two locking holes, allowing for the installation and removal of the wiping rings. The two wiping rings merge to form a circle. To accommodate steel wires of different thicknesses, wiping rings of different sizes can be replaced, resulting in higher efficiency.
[0021] 3. In this embodiment of the invention, by pulling the block to move the movable cylinder to one side, the guide roller can be disassembled for replacement and surface cleaning. The limit telescopic rod two and the spring two limit the movable cylinder, which facilitates the installation of the guide roller. The guide roller has protrusions on both sides, which are embedded in the grooves inside the spring two and the fixed cylinder to limit the guide roller and prevent unnecessary rotation after the guide roller is installed inside, thus reducing its wear.
[0022] In this invention, after the steel wire is drawn out of the zinc pot, it first passes through a primary limiting assembly (elastic clamping semicircular blocks). With the cooperation of a spring and a limiting telescopic rod, the two clamping semicircular blocks apply a moderate radial clamping force to the steel wire, eliminating initial vibration during lead-out and providing initial guidance. Simultaneously, due to the elastic clamping, the clamping force can be adaptively adjusted according to changes in the steel wire's diameter, preventing plating wear due to excessive clamping force. After passing through the primary limiting assembly, the vibration amplitude of the steel wire is initially suppressed. At this point, the steel wire is guided and limited by the guide roller, further reducing its sway. Subsequently, the steel wire enters the secondary limiting assembly (a first magnet and a second magnet). Under the stabilizing effect of the primary limiting assembly, the steel wire enters the magnetic limiting area with a smaller vibration amplitude. Here, the magnetic field formed by the first and second magnets applies a non-contact constraint force to the steel wire, further suppressing its radial vibration. In this invention, the relative arrangement of the first and second magnets can be achieved in one of the following two ways: Method 1: The first and second magnets have the same magnetic pole (e.g., both are N poles). In this case, a repulsive force field is generated between the two magnets. When the steel wire passes between the two magnets, if the steel wire deviates to one side, the repulsive force pushes the steel wire to the other side, thereby suppressing its radial vibration. The advantage of this arrangement is its rapid response and short response time. Method 2: The first and second magnets have opposite magnetic poles (e.g., one is an N pole and the other is an S pole). In this case, an attractive force field is generated between the two magnets. The attractive field exerts an inward constraint force on the steel wire, keeping it in the center of the magnetic field. The advantage of this arrangement is its good stability and uniform constraint force. Since the magnetic limit does not contact the steel wire, mechanical contact avoids wear on the coating. Finally, the steel wire passes through the wiping assembly, where two wiping rings close to form a circle, wiping the zinc liquid on the surface of the steel wire to remove excess zinc liquid and control the coating thickness. Through the synergistic effect of the two-layer limit, the first-level limit eliminates the initial jitter and creates stable conditions for the second-level limit. Under stable conditions, the second-level limit further suppresses the running jitter, so that the steel wire is in a stable position when passing through the wiping component, the coating thickness is uniform, and the product quality is significantly improved.

[0033] 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 of ordinary skill in the art without creative effort are within the scope of protection of the present invention.
[0034] Example 1: A primary limiting component is installed at the zinc pot outlet to provide contact-type limiting for the outgoing steel wire; a secondary limiting component is installed downstream of the primary limiting component to provide non-contact limiting for the steel wire; and a wiping component is installed downstream of the secondary limiting component to wipe the steel wire.
[0035] To further understand, the steel wire 107 is first sent out from the inside of the zinc pot 102. The steel wire 107 passes through the inside of the two clamping semicircular blocks 106 and is sent out from the inside of the zinc pot 102. At this time, the two clamping semicircular blocks 106 clamp and limit the steel wire 107 under the cooperation of the limiting telescopic rod 105 and the spring 104, which can reduce the shaking of the steel wire 107 when it is sent out from the inside of the zinc pot 102.
[0036] Example 2:
[0037] like Figures 1 to 6 As shown, the primary limiting assembly includes a rear plate 101, a zinc pot 102, a spring 104, a limiting telescopic rod 105, and a clamping semicircular block 106. The zinc pot 102 is fixedly installed at the bottom of the rear plate 101. Springs 104 are fixedly installed on opposite sides of the inner wall of the zinc pot 102. Limiting telescopic rods 105 are fixedly installed on opposite sides of the inner wall of the zinc pot 102. Clamping semicircular blocks 106 are fixedly installed at opposite ends of the two limiting telescopic rods 105 and the two springs 104. A steel wire 107 passes through the interior of the two clamping semicircular blocks 106 to limit its movement and reduce the vibration of the steel wire 107 during movement. A cooling mechanism 2 is also provided at the top of the rear plate 101 to cool the steel wire after passing through the guide roller and accelerate the solidification of the zinc liquid. A thickness control device 3 is also provided at the top of the rear plate 101 to monitor the coating thickness on the surface of the steel wire in real time and adjust the pressure of the wiping assembly according to the thickness.
[0038] To further understand, by setting a primary limiting assembly consisting of a spring-104, a limiting telescopic rod-105, and a clamping semicircular block-106 at the outlet of the zinc pot 102, the elastic cooperation between the spring-104 and the limiting telescopic rod-105 enables the two clamping semicircular blocks-106 to apply a moderate radial clamping force to the steel wire 107.
[0039] The positive effects of this design are as follows: Elimination of initial vibration: It effectively eliminates the initial vibration when the steel wire 107 is led out of the zinc pot 102, providing a stable initial guide for the steel wire 107. Adaptive adjustment and protective coating: Due to the use of an elastic clamping structure, the clamping force can be adaptively adjusted according to the diameter change of the steel wire 107. This not only enhances the versatility of the device but also avoids the problem of wear on the surface coating of the steel wire 107 due to excessive clamping force.
[0040] The cooling mechanism 2 provided on the top of the rear plate 101 is used to cool the steel wire 107 after passing through the guide roller 112.
[0041] Its positive effects are as follows: by setting a cooling mechanism 2 on the top of the rear plate 101, the steel wire 107 immediately enters the forced cooling stage after leaving the zinc pot 102 and passing through the guide roller. Since the solidification time of the hot-dip galvanized layer is greatly shortened, the "sag" phenomenon of zinc liquid under gravity and the "zinc streaks" defect caused by the slight movement of the steel wire 107 are effectively suppressed, and the smoothness of the surface of the steel wire 107 is significantly improved.
[0042] The controlled cooling rate provided by the cooling mechanism 2 helps to refine the grain structure on the zinc layer surface, enhance the density and adhesion of the coating, thereby improving the corrosion resistance of the steel wire 107 and making it less prone to coating peeling during subsequent bending or drawing processes.
[0043] Through the active cooling mechanism 2, the complete solidification point of the molten zinc on the surface of the steel wire 107 is advanced. This not only reduces the risk of heat damage to subsequent take-up equipment, but also allows for increased production line speed within a limited factory space, thereby improving overall production efficiency.
[0044] The thickness control device 3 installed on the top of the rear plate 101 enables real-time monitoring of the coating thickness on the surface of the steel wire 107.
[0045] Its positive effect is that a dynamic feedback loop is formed between the thickness control device 3 and the wiping assembly. The thickness control device 3 can capture the micron-level fluctuations in the coating thickness of the steel wire 107 in real time and automatically transmit electrical signals to the actuator to adjust the pressure of the wiping assembly. This closed-loop control replaces traditional manual observation and adjustment, eliminates human experience errors, and ensures a high degree of consistency in coating thickness.
[0046] During high-speed production, the positional drift of the steel wire 107 can easily lead to uneven coating thickness (i.e., eccentricity). The thickness control device 3, through real-time monitoring of the circumferential thickness, can guide the wiping assembly to quickly compensate for pressure deviations, ensuring uniform coating distribution in the circumferential direction of the steel wire 107, and greatly reducing the defect rate.
[0047] By precisely adjusting the thickness control device 3, the coating thickness can be stably controlled within the range slightly above the lower limit of the process requirements, avoiding excessive consumption of zinc liquid (ultra-thick coating) due to insufficient wiping. In large-scale continuous production, this can save enterprises a significant amount of zinc ingot raw material costs, resulting in significant economic benefits.
[0048] Example 3:
[0049] like Figures 1 to 6As shown, two vertical bars 114 are fixedly installed on the top of the rear plate 101. Multiple limiting rods 116 are fixedly installed on the opposite side of the two vertical bars 114. Second magnets 118 are fixedly installed on the outer surface of the multiple limiting rods 116. Slider 1171 is slidably connected to the outer surface of the multiple limiting rods 116. An electric push rod 115 is fixedly installed on one side of one of the vertical bars 114. The output end of the electric push rod 115 is fixedly installed on one side of the slider 1171. A first magnet 117 is fixedly installed at the bottom of the slider 1171. A steel wire 107 passes through the opposite surface of the first magnet 117 and the second magnet 118 to limit their movement.
[0050] To further understand, by activating the electric push rod 115 through an external power source, the slider 1171 is pushed to slide on the outer surface of the limiting rod 116, thereby driving the first magnet 117 at the bottom to move. The distance between the first magnet 117 and the second magnet 118 can be adjusted to accommodate steel wires 107 of different thicknesses. The wires 107 of different thicknesses can be limited to prevent them from shaking. By setting the second magnet 118 and the first magnet 117 together, the wires 107 can be limited without contacting each other, thus reducing their shaking.
[0051] Cooling mechanism 2 is located on top of the rear plate 101, between the guide roller 112 and the secondary limiting assembly. Cooling mechanism 2 includes a wind box, a fan, and a duct. The fan is installed inside the wind box, the air inlet of the duct is connected to the fan, and the air outlet of the duct faces the steel wire 107. After the fan starts, cold air is blown onto the steel wire 107 through the duct, cooling the steel wire 107, accelerating the solidification of the zinc liquid, and improving...
[0052] Coating quality. The technical parameters of cooling mechanism 2 are as follows: Fan power: 0.5-2 kW
[0053] Wind speed: 5-20 m / s, cooling temperature: room temperature to -20℃.
[0054] Example 4:
[0055] like Figures 1 to 6As shown, the top of the rear plate 101 is provided with multiple U-shaped blocks 119, which are divided into two groups. One group of U-shaped blocks 119 has a threaded rod 120 threaded inside, and the other group of U-shaped blocks 119 has a short rod 121 movably embedded inside. The bottom of the multiple threaded rods 120 is rotatably mounted with a locking block through a bearing. The multiple U-shaped blocks 119 are fixedly mounted on the top of the locking block. A long strip 126 is fixedly mounted on one side of the other group of U-shaped blocks 119. The top of the rear plate 101 has a threaded rod 124 threaded inside, and a limiting rod 125 movably embedded on the top of the rear plate 101. The threaded rod 124 is mounted on one side of the long strip 126 through a bearing, and the limiting rod 125 is fixedly mounted on one side of the long strip 126. Wiping rings 122 are detachably installed inside the multiple U-shaped blocks 119, and the multiple wiping rings 122 are on opposite sides. Multiple locking holes 123 are opened on the outer surface of the multiple U-shaped blocks 119.
[0056] To further understand, by rotating the threaded rod 124, the long strip 126 moves back and forth under the limitation of the limiting rod 125, thereby driving one set of wiping rings 122 to move. This allows the steel wire 107 to be easily placed between the two wiping rings 122. Simultaneously, rotating the threaded rod 120, under the limitation of the short rod 121, moves the bottom locking block. The bottom of the locking block has two locking rods that respectively engage with the two locking holes 123, allowing the wiping rings 122 to be installed and removed. The two wiping rings 122 merge to form a circle. To accommodate steel wires 107 of different thicknesses, wiping rings 122 of different sizes can be replaced, resulting in higher efficiency.
[0057] Working principle: During use, the steel wire 107 is first fed out from inside the zinc pot 102. The steel wire 107 passes through the inside of two clamping semicircular blocks 106 and is then fed out of the zinc pot 102. At this time, the cooperation of the limiting telescopic rod 105 and the spring 104 causes the two clamping semicircular blocks 106 to clamp and limit the steel wire 107, reducing the vibration of the steel wire 107 as it is fed out of the zinc pot 102.
[0058] The formula for calculating the clamping force is:
[0059] in, The clamping force is the resultant radial clamping force exerted by the two clamping semicircles on the steel wire. The spring constant of spring one ranges from 100 to 500 N / m. The compression of spring one is denoted as 0.005-0.02 m.
[0060] At this time, the steel wire 107 passes over the upper surface of the guide roller 112. The guide roller 112 is mounted on the rear plate 101 by bearings and can rotate with the movement of the steel wire 107, reducing the wear of the steel wire 107 and preventing the zinc on the surface of the steel wire 107 from being worn away. The guide roller 112 guides and limits the steel wire 107 to prevent the steel wire 107 from deviating in angle after being sent out, so that the steel wire 107 is in a straight line. After passing through the guide roller 112, the steel wire 107 is cooled by the cooling mechanism 2. When the steel wire 107 passes over the opposing surfaces of the second magnet 118 and the first magnet 117, the first magnet 117 and the second magnet 118 attract or repel each other, which further reduces the vibration of the steel wire 107 when passing through. By setting up a double-layer anti-vibration structure, the subsequent wiping effect is better, the vibration is reduced, and the wiping thickness is more uniform. The steel wire passes through the middle of two wiping rings 122, which merge into a circle to wipe the zinc on the surface of the steel wire before proceeding to the next process.
[0061] By pulling the block 111, the movable cylinder 110 can be moved to one side, allowing the guide roller 112 to be disassembled for replacement and surface cleaning. The limit telescopic rod 109 and spring 108 limit the movable cylinder 110, facilitating the installation of the guide roller 112. The guide roller 112 has protrusions on both sides, which are embedded in the grooves 1081 inside the spring 108 and the fixed cylinder 113 to limit the guide roller 112, preventing unnecessary rotation after installation and reducing wear.
[0062] The electric push rod 115 is activated by an external power source to push the slider 1171 to slide on the outer surface of the limiting rod 116, thereby driving the first magnet 117 at the bottom to move. The distance between the first magnet 117 and the second magnet 118 can be adjusted to accommodate steel wires 107 of different thicknesses. The wires 107 of different thicknesses can be limited to prevent them from shaking. By setting the second magnet 118 and the first magnet 117 together, the wires 107 can be limited without contacting each other, thus reducing their shaking.
[0063] By rotating the threaded rod 124, the long strip 126 moves back and forth under the limitation of the limiting rod 125, thereby driving one set of wiping rings 122 to move. This allows the steel wire 107 to be easily placed between the two wiping rings 122. Simultaneously, rotating the threaded rod 120, under the limitation of the short rod 121, moves the bottom locking block. The bottom of the locking block has two locking rods that respectively engage with the two locking holes 123, allowing the wiping rings 122 to be installed and removed. The two wiping rings 122 merge to form a circle. To accommodate steel wires 107 of different thicknesses, wiping rings 122 of different sizes can be replaced, resulting in higher efficiency.
[0064] The following experimental data were obtained under the following test conditions: zinc pot temperature maintained at 450℃-460℃, steel wire diameter 2.0mm, and operating speed 100m / min. 100 samples were randomly selected from each test group for testing, and the test methods referenced relevant national industry standards for galvanized steel wire.
