Description

Technical Field

[0001] This invention relates to the field of steel wire surface treatment equipment technology, and in particular to a continuous hot-dip galvanizing forming device for multi-specification steel wires. Background Technology

[0002] Hot-dip galvanizing is one of the core processes for corrosion protection of steel wire. It involves immersing the steel wire in molten zinc to form a zinc coating on its surface, thereby improving its corrosion resistance and service life. Current continuous hot-dip galvanizing equipment for steel wire has the following shortcomings in actual production: First, the guiding and wire-passing structures are mostly of fixed aperture, which can only accommodate steel wires of a single or small range of diameters. When changing product specifications, the entire guiding mold must be replaced, resulting in low changeover efficiency and high production costs. Second, the tension adjustment capability during steel wire conveying is poor, easily leading to slack and shaking, resulting in defects such as uneven coating thickness and incomplete coating. Third, the depth of steel wire immersion in zinc liquid is mostly fixed, making it impossible to flexibly adjust the immersion time according to steel wire specifications and wire feeding speed, making it difficult to adapt to the production needs of different coating thicknesses. Fourth, local temperature differences easily occur in the zinc liquid inside the galvanizing tank, with poor temperature consistency between the zinc liquid near and away from the heating zone, affecting the quality of coating crystallization. Fifth, the means of controlling the coating thickness after galvanizing are limited, mostly using a single wiping structure, resulting in insufficient surface homogenization of the coating, easily leading to problems such as zinc nodules and uneven thickness, ultimately affecting the quality of the finished product. Summary of the Invention

The inner side of the flexible wiping block is provided with an arc-shaped fitting surface to adapt to the surface of steel wires of different diameters, and the rear end of the flexible wiping block is provided with an elastic compression spring.

[0013] The beneficial effects of the present invention are: (1) Strong adaptability to multiple specifications: The diameter guide component driven by the worm gear can be adjusted synchronously to form the wire passage diameter by multiple guide petals. Combined with the multiple annular wire passage grooves on the dip-plating pressure roller, it can quickly adapt to the production of steel wires of different diameter specifications without changing the core mold, greatly improving the changeover efficiency and reducing the production auxiliary cost.

[0014] (2) Stable and reliable conveying tension: The counterweight adaptive tensioning component is adopted. The tensioning swing arm is driven by the gravity of the counterweight to compensate for the tension fluctuation during the steel wire conveying process in real time, ensuring that the steel wire is always in a stable tension state and avoiding problems such as uneven coating thickness and wire deviation caused by uneven tension. At the same time, different tension requirements can be adapted by replacing counterweights of different weights or adjusting the hinge hole position.

[0015] (3) The immersion depth is flexible and adjustable: the immersion pressure roller is driven to move up and down by the screw lifting structure, which can accurately adjust the depth of the steel wire immersed in the zinc liquid, thereby controlling the immersion time of the steel wire, adapting to different coating thickness requirements and different wire feeding speeds in production scenarios. The adjustment process is stable and precise, and has good self-locking properties.

[0016] (4) Uniform zinc bath temperature: The zinc bath is equipped with a flow guide and temperature equalization component. The zinc bath is driven to circulate by a centrifugal impeller. The vertical guide plate forms a directional flow channel, so that the temperature and composition of the zinc bath are uniform throughout the zinc bath, eliminating local temperature differences and improving the crystallization quality and adhesion of the coating.

[0017] (5) Uniform and controllable coating quality: After plating, the coating thickness control component and the coating homogenization component are set in sequence. The flexible wiping block can adapt to the steel wire surface, scrape off excess zinc liquid and initially control the coating thickness. Then, the rotating ceramic roller rolls the coating to homogenize it, eliminate zinc nodules and zinc marks, and make the coating thickness more uniform and the surface smoother.

[0018] (6) High efficiency and stability of cooling and shaping: The air-cooled cooling and shaping structure is adopted, with multiple sets of air nozzles surrounding the steel wire to uniformly cool the steel wire after plating, so that the zinc coating can quickly crystallize and shape, avoid damage to the coating during subsequent transportation, and ensure the stability of the appearance and performance of the finished product.

Detailed Implementation

[0028] like Figures 1 to 8 As shown, the specific embodiment adopts the following technical solution: a multi-specification steel wire continuous hot-dip galvanizing forming device, including a frame 1, a left support frame 2, a variable diameter guide component 3, an adaptive tensioning component 4, a galvanizing pool 5, an immersion depth adjustment component 6, a flow guiding and temperature equalization component, a right support frame 7, a coating thickness control component 8, a coating homogenization component 9, and a cooling and shaping component 10.

[0029] The frame 1 serves as an integral load-bearing foundation, constructed from welded steel profiles, with a horizontal mounting surface on its upper surface. A left support frame 2 is bolted to the left side of the upper surface of the frame 1, and a right support frame 7 is bolted to the right side. The left and right support frames 2 and 7 respectively support the functional components on the inlet and outlet sides. An adaptive tensioning assembly 4 and a galvanizing tank 5 are fixedly connected to the middle of the upper surface of the frame 1. The adaptive tensioning assembly 4, located to the left of the galvanizing tank 5, is used to adjust the tension of the incoming steel wire. The galvanizing tank 5 is an open-topped tank structure filled with molten zinc, serving as the work station for hot-dip galvanizing the steel wire. Along the wire feeding direction, the upper surface of the right support frame 7 is sequentially equipped with a coating thickness control assembly 8, a coating homogenization assembly 9, and a cooling and shaping assembly 10, which sequentially complete the post-plating coating thickness control, surface homogenization, and cooling and shaping operations. The upper left side of the galvanizing tank 5 is provided with an immersion depth adjustment component 6, which is used to control the depth of the steel wire immersed in the zinc liquid; the interior of the galvanizing tank 5 is provided with a flow guiding and temperature equalization component, which is used to drive the zinc liquid to circulate and ensure uniform temperature in the tank.

[0030] like Figure 2 As shown, the variable diameter guide assembly 3 includes a variable diameter guide assembly housing 31, a fixing ring 32, gears 33, guide petals 34, a worm gear 35, internal gears 36, a worm 37, a first handwheel 38, and a first bearing 39. The variable diameter guide assembly housing 31 is a cylindrical shell, fixedly connected to the side wall of the left support frame 2 via a flange structure, with its axis aligned with the wire feeding direction. A fixing ring 32 is fixedly connected to the cavity of the variable diameter guide assembly housing 31, and the fixing ring 32 is coaxially arranged with the housing. Several gears 33 are hinged in a circular array on the side wall of the fixing ring 32. In this embodiment, eight sets of gears 33 are provided. A guide petal 34 is fixedly connected to the end face of each gear 33. The guide petal 34 has an arc-shaped petal structure, and multiple sets of guide petals 34 surround to form a central wire-passing hole for the wire to pass through. A worm gear 35 is movably connected to the cavity of the variable diameter guide assembly housing 31 via a rotary support. An internal gear 36 is integrally formed on the inner wall of the worm gear 35. The internal gear 36 meshes with all gears 33 simultaneously. When the worm gear 35 rotates, it can synchronously drive all gears 33 to rotate via the internal gear 36, thereby causing the guide flap 34 to swing synchronously, realizing the expansion and contraction of the central through-hole diameter. A worm 37 is movably connected to the upper end of the variable diameter guide assembly housing 31 via a first bearing 39. The worm 37 meshes with the external teeth of the worm gear 35. A first handwheel 38 is fixedly connected to the side end of the worm 37 extending out of the housing. During operation, rotating the first handwheel 38 drives the worm 37 to rotate. The worm 37 and the worm wheel 35 mesh and drive the worm wheel 35 to rotate. Then, through the transmission of the internal gear 36 and the gear 33, all guide petals 34 open and close synchronously, thereby adjusting the wire guide hole diameter to adapt to steel wires of different diameters. Moreover, the worm wheel and worm gear structure has a self-locking characteristic, and the hole diameter can remain stable after adjustment.

[0031] like Figure 3 As shown, the adaptive tensioning assembly 4 includes a support arm 41, a tensioning swing arm 42, adjustment holes 43, a first guide pulley 44, a hanger 45, and a counterweight 46. The support arm 41 is vertically fixed to the upper surface of the frame 1; the tensioning swing arm 42 is a long strip-shaped arm, with the first guide pulley 44 rotatably connected to its left end, and a steel wire passing through the groove of the first guide pulley 44; the hanger 45 is fixedly connected to the right end of the tensioning swing arm 42, and the counterweight 46 is suspended on the hanger 45. The counterweight 46 can be replaced with different weight specifications according to the tension requirements. A row of adjustment holes 43 is provided along the length of the arm at the middle position of the tensioning swing arm 42. The tensioning swing arm 42 is hinged to the upper end of the support arm 41 through the corresponding adjustment holes 43 by a pin, forming a lever structure. During operation, the weight of the counterweight 46 causes the tensioning swing arm 42 to swing clockwise around the hinge point, thereby applying tension to the steel wire through the first guide pulley 44. When the tension of the steel wire fluctuates, the tensioning swing arm 42 can adaptively swing slightly to compensate for the tension change in real time, ensuring that the steel wire is always in a stable tension state. Changing the position of the adjustment hole 43 of the hinge can adjust the lever arm ratio and further expand the tension adjustment range.

[0032] like Figure 4As shown, the immersion depth adjustment assembly 6 includes an immersion depth adjustment assembly bracket 61, bushings 62, lifting rods 63, guide rods 64, lead screws 65, a second handwheel 66, a second bearing 67, mounting plates 68, immersion pressure rollers 69, and an annular wire guide groove 610. The immersion depth adjustment assembly bracket 61 is a portal frame structure, fixedly connected to the upper left side of the galvanizing tank 5, spanning across the top of the galvanizing tank 5. Bushings 62 are slidably connected to the front and rear columns of the immersion depth adjustment assembly bracket 61, and a horizontally arranged lifting rod 63 is fixedly connected between the two bushings 62. Vertically downward mounting plates 68 are fixedly connected to both sides of the lower end of the lifting rod 63, and an immersion pressure roller 69 is movably connected between the two mounting plates 68 through the second bearing 67. The immersion pressure roller 69 is horizontally arranged and its axis is perpendicular to the wire feeding direction. The outer cylindrical surface of the immersion roller 69 is provided with several annular wire guide grooves 610, each with a different diameter to accommodate steel wires of different specifications and prevent the steel wire from shifting left or right during feeding. A vertically arranged lead screw 65 is movably connected to one column inside the immersion depth adjustment component bracket 61 via a second bearing 67. A second handwheel 66 is fixedly connected to the top of the lead screw 65. A vertically arranged guide rod 64 is fixedly connected to the other column inside the immersion depth adjustment component bracket 61. One end of the lifting rod 63 is threadedly connected to the lead screw 65 via a nut, and the other end is slidably connected to the guide rod 64 via a sliding sleeve. During operation, rotating the second handwheel 66 drives the lead screw 65 to rotate, which in turn drives the lifting rod 63 to move up and down along the guide rod 64 via threaded transmission, thereby raising and lowering the immersion roller 69 and adjusting the depth of the steel wire pressed into the zinc bath, thus controlling the immersion time. The lead screw transmission has a self-locking capability, ensuring a stable immersion depth after adjustment.

[0033] like Figure 5As shown, the flow guiding and temperature equalization assembly includes a vertical flow guide plate 701, a first motor 702, a rotating shaft 703, a second guide pulley 704, a connecting hole 705, and a centrifugal impeller 706. The vertical flow guide plate 701 is fixedly connected to the middle of the interior of the galvanizing tank 5, dividing the interior of the galvanizing tank 5 into left and right chambers. The second guide pulley 704 is rotatably connected to the top of the vertical flow guide plate 701 to support the steel wire's deflection. A connecting hole 705 is provided at the bottom of the vertical flow guide plate 701, connecting the bottoms of the left and right chambers. A vertically arranged rotating shaft 703 is movably connected to the bottom surface of the interior of the galvanizing tank 5 via a second bearing 67. Several centrifugal impellers 706 are fixedly connected axially to the rotating shaft 703. The first motor 702 is fixedly connected to the bottom surface of the outer side of the galvanizing tank 5, and the output end of the first motor 702 is fixedly connected to the lower end of the rotating shaft 703. During operation, the first motor 702 drives the rotating shaft 703 to rotate the centrifugal impeller 706, which drives the zinc liquid in one side chamber to flow upward. The zinc liquid passes over the vertical guide plate 701 at the top and enters the other side chamber, and then flows back through the bottom connecting hole 705, forming a directional circulation channel. This ensures that the temperature and composition of the zinc liquid in the pool are mixed evenly, eliminates local temperature differences, and ensures a consistent immersion environment.

[0034] like Figure 6 As shown, the coating thickness control component 8 includes a coating thickness control component housing 81, an annular seat 82, and flexible wiping blocks 83. The coating thickness control component housing 81 is fixedly connected to the right support frame 7; the annular seat 82 is fixedly connected to the coating thickness control component housing 81, and the annular seat 82 is coaxial with the wire feeding direction; several flexible wiping blocks 83 are connected in a circular array in the annular seat 82, and in this embodiment, three sets of flexible wiping blocks 83 are provided. The flexible wiping blocks 83 are made of high-temperature resistant and wear-resistant graphite felt material, and multiple flexible wiping blocks 83 surround to form a variable diameter wire passage hole. The inner side of the flexible wiping block 83 is provided with an arc-shaped contact surface, which can adaptively fit the surface of steel wires of different diameter specifications; and the rear end of the flexible wiping block 83 is provided with an elastic compression spring, which can continuously apply a compression force to the surface of the steel wire. When the coated steel wire passes through the center, the flexible wiping block 83 scrapes off the excess zinc liquid on the surface of the steel wire, initially controlling the coating thickness, and can adapt to changes in the diameter of the steel wire within a certain range.

[0035] like Figure 7As shown, the plating homogenization component 9 includes a plating homogenization component housing 91, a homogenization rotating seat 92, a third bearing 93, cylindrical ceramic rollers 94, a first gear 95, a second gear 96, and a second motor 97. The plating homogenization component housing 91 is fixedly connected to the right support frame 7. The homogenization rotating seat 92 is movably connected to the cavity of the plating homogenization component housing 91 through two sets of third bearings 93. The homogenization rotating seat 92 has a cylindrical structure and is coaxial with the wire feeding direction. Several inclined cylindrical ceramic rollers 94 are connected in a circular array on the inner wall of the homogenization rotating seat 92. The axis of the ceramic rollers forms a certain angle with the wire feeding axis, and all the ceramic rollers enclose a channel for the steel wire to pass through. A first gear 95 is fixedly connected to the middle of the outer surface of the homogenizing rotating seat 92; a second motor 97 is fixedly connected to the bottom of the cavity of the coating homogenizing component cover 91; a second gear 96 is fixedly connected to the output end of the second motor 97, and the second gear 96 meshes with the first gear 95. During operation, the second motor 97 drives the homogenizing rotating seat 92 to rotate around its axis through gear transmission, causing the internal cylindrical ceramic rollers 94 to revolve around the steel wire. At the same time, the rollers themselves can rotate, rolling and homogenizing the zinc coating on the surface of the steel wire, rolling the initially controlled coating evenly, eliminating defects such as zinc nodules and zinc flow marks, and improving the surface smoothness and thickness consistency of the coating.

[0036] like Figure 8 As shown, the cooling and shaping assembly 10 includes a cooling and shaping chamber 101, an air cooler 102, an air duct 103, and air nozzles 104. The cooling and shaping chamber 101 is a horizontal cylindrical cavity, fixedly connected to the rightmost end of the right support frame 7. An air cooler 102 is fixedly connected to the top of the cooling and shaping chamber 101 to generate cooling airflow. Several air nozzles 104 are fixedly connected to the inner wall of the cooling and shaping chamber 101, evenly arranged circumferentially with their outlets facing the central steel wire. The air nozzles 104 are connected to the outlet of the air cooler 102 via the air duct 103. During operation, the cooling airflow generated by the air cooler 102 is delivered to each air nozzle 104 via the air duct 103, blowing evenly onto the surface of the steel wire from all sides, causing the high-temperature zinc plating to cool, crystallize, and solidify rapidly, preventing adhesion and scratches during subsequent winding, and ensuring the quality of the finished plating.

[0037] The usage state of this invention is as follows: the steel wire to be galvanized enters from the left side, first passes through the center wire hole of the variable diameter guide assembly 3, and the opening and closing degree of the guide flap 34 is adjusted by rotating the first handwheel 38 according to the diameter of the steel wire, so that the guide structure is accurately adapted to the steel wire specification and ensures the wire feeding is centered; then the steel wire passes around the first guide pulley 44 of the adaptive tensioning assembly 4 and is kept in a stable tension state under the action of the counterweight 46.

[0038] After being tensioned, the steel wire enters the galvanizing bath 5 above and is pressed into the zinc liquid by the immersion pressure roller 69 of the immersion depth adjustment component 6. The height of the immersion pressure roller 69 is adjusted by rotating the second handwheel 66 according to production needs, thereby controlling the immersion depth and immersion time of the steel wire in the zinc liquid. After being turned by the second guide pulley 704 in the zinc liquid, the steel wire is led out upward. The flow guiding and temperature equalization component inside the galvanizing bath 5 continuously drives the zinc liquid circulation to ensure uniform temperature in the bath.

[0039] After being drawn out of the galvanizing bath 5, the galvanized steel wire first enters the coating thickness control component 8, where a flexible wiping block 83 scrapes off excess zinc liquid from the surface, initially controlling the coating thickness. Then it enters the coating homogenization component 9, where rotating cylindrical ceramic rollers 94 roll and homogenize the coating, improving coating uniformity and surface quality. Finally, the steel wire enters the cooling and shaping component 10, where it is rapidly cooled and shaped by a surrounding air-cooling system. After completing the entire hot-dip galvanizing forming process, the wire exits from the right side.
