Description

TECHNICAL FIELD

[0001] The present application belongs to the field of hot-dip galvanizing, in particular to a double-shaft linkage galvanizing machine device. BACKGROUND

[0002] In recent years, with the rapid development of national infrastructure and urban construction, especially in the decoration and beautification of bridge construction and urban curtain wall, the demand for galvanized rectangular steel pipes has increased dramatically. In particular, the demand for rectangular hot-dip galvanized pipes has increased year by year due to their thin thickness and light weight. The existing steel pipe hot-dip galvanizing enterprises cannot meet the market demand for rectangular steel pipes.

[0003] In the production of hot-dip galvanized rectangular pipes, in order to improve production efficiency, multiple steel pipes are usually placed in the zinc pot at the same time, and then drawn out of the zinc pot at the same time. Since the steel pipe is a hollow pipe structure, its sinking speed is slow after entering the zinc pot. In order to improve the sinking efficiency, a push rod is usually used to press down the steel pipe. When producing steel pipes with small outer diameter or low wall thickness, pressing down the middle or one end of the steel pipe with the push rod will cause the steel pipe to bend, affecting the production quality. SUMMARY

[0004] Therefore, the present application aims to provide a double-shaft linkage galvanizing machine device to solve the problem of low efficiency of natural immersion of steel pipes in the zinc pot in the prior art, and the problem of easy bending of steel pipes when using a push rod to press down.

[0005] To achieve the above-mentioned purposes, the technical scheme of the present application is as follows:

[0021] Compared with the prior art, the dual-axis linkage galvanizing machine device of the present invention has the following beneficial effects:

[0022] (1) The dual-axis linkage galvanizing machine device of the present invention clamps the steel pipe and presses the steel pipe into the zinc material through the material transfer mechanism, which can increase the speed at which the steel pipe sinks into the molten zinc material, so as to improve the galvanizing efficiency. Moreover, through the pressing of the material transfer mechanism, the pressing pressure and speed of multiple steel pipes are the same during production, which can prevent the steel pipe from deforming and ensure the consistency of production quality. Furthermore, the galvanized steel pipe in the molten zinc material can be retrieved through the material transfer mechanism to cooperate with the work of the upper drawing mechanism, reducing the investment of other equipment and reducing equipment costs.

[0023] (2) The dual-axis linkage galvanizing machine device of the present invention has multiple clamping units arranged along the axial direction of the steel pipe. The execution end of each clamping unit can clamp to the periphery of the steel pipe. By setting multiple clamping units to apply pressure to the periphery of the steel pipe in sections, it is possible to prevent the steel pipe from being pressed into an arc-shaped structure when pressing the periphery of the steel pipe, so as to meet the requirements of various working conditions and meet the galvanizing requirements of thin-walled square and rectangular tubes.

[0024] (3) In the dual-axis linkage galvanizing machine device of the present invention, the upper end of the clamping rod is eccentrically installed to the execution end of the rotating component so that when the rotating component drives the clamping rod to rotate, the steel pipe clamping structure is opened and closed. A first guide bevel is provided at the inlet end of the clamping slot to facilitate guiding the outer periphery of the steel pipe to the clamping slot, reducing the influence of the motion tolerance of the transmission component on the clamping operation and improving the reliability of the device clamping.

[0025] (4) The dual-axis linkage galvanizing machine device of the present invention has a detachable limit plate installed at the lower end of the clamping rod. The purpose of setting the limit plate is to facilitate the adjustment of the size of the clamping slot. When changing production specifications, only the limit plate needs to be replaced to adjust the size of the clamping slot to be adapted, thereby improving the convenience of maintenance.

[0026] (5) The dual-axis linkage galvanizing machine device of the present invention has a steel pipe hanging in the hanging structure. By adjusting the relative height of different hanging structures, the relative tilt angle of the steel pipe in the zinc pot can be adjusted so as to match the upward pulling mechanism and meet the working conditions of the upward pulling mechanism. Furthermore, a third guide bevel is provided at the inlet end of each hanging groove to facilitate the outer side of the steel pipe to slide into the hanging structure. Attached Figure Description

Those skilled in the art will understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0042] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0043] like Figures 1-9 As shown, a dual-shaft linkage galvanizing machine includes a zinc pot 1, a material conveying mechanism, an upward guiding mechanism, and a material limiting component 2. The zinc pot 1 is filled with molten zinc. The material limiting component 2 is installed inside the zinc pot 1 to limit the relative position of steel pipes 3 within the zinc pot 1. A material conveying mechanism is provided on one side of the zinc pot 1. The material conveyor is a prior art chain conveyor, capable of stacking the steel pipes 3 to be galvanized at equal intervals on one side of the zinc pot 1. Without a chain conveyor, the steel pipes 3 to be galvanized need to be manually stacked at equal intervals so that the material conveying mechanism can transport them. A material transfer mechanism 4 is provided on the zinc pot 1, and an upward guiding mechanism is provided on one side of the material transfer mechanism 4. The upward guiding mechanism is a prior art magnetic suction roller, such as the traction component recorded in application number CN2025110789252, invention titled "Hot-dip Galvanizing Device for Thin-walled Square Tubes." Its structural principle will not be elaborated here. The material transfer mechanism 4 is used to transfer the steel pipes 3 to the zinc pot 1... The steel pipe 3 is transferred to the lower part of the upward drawing mechanism. The upward drawing mechanism can magnetically attract the galvanized steel pipe 3 and draw it out of the zinc pot 1. The execution end of the material transfer mechanism 4 can clamp the outer periphery of the steel pipe 3 to be galvanized on the material conveying mechanism and press the steel pipe 3 into the molten zinc material, and then release it onto the material limiting component 2. The execution end of the material transfer mechanism 4 can adjust the relative position of the steel pipe 3 on the material limiting component 2, and can cooperate with the upward drawing mechanism to draw the galvanized steel pipe 3 out of the zinc pot 1. By clamping the steel pipe 3 and pressing it into the zinc material, the speed at which the steel pipe 3 sinks into the molten zinc material can be increased, so as to improve the galvanizing efficiency. Moreover, by pressing multiple steel pipes 3 during production, the pressure and speed of pressing are the same, which can prevent the shape of the steel pipe 3 from being deformed and ensure the consistency of production quality. The material transfer mechanism 4 can also scoop up the galvanized steel pipe 3 in the molten zinc material to cooperate with the work of the upward drawing mechanism, reducing the investment of other equipment and reducing equipment costs.

[0044] The material transfer mechanism 4 includes multiple clamping units arranged along the axial direction of the steel pipe 3. The actuating end of each clamping unit can clamp to the periphery of the steel pipe 3. By setting multiple clamping units to apply pressure to the periphery of the steel pipe 3 in sections, pressure is applied to the periphery of the steel pipe 3 to prevent the steel pipe 3 from being pressed into an arc-shaped structure when pressing the periphery of the steel pipe 3. To meet the needs of various working conditions and the galvanizing requirements of thin-walled square and rectangular tubes, multiple clamping units move synchronously via a transmission assembly 41 to improve their synchronization. Each clamping unit includes a rotating assembly 42, a lifting assembly 43, and multiple clamping rods 44. The clamping rods 44 are arranged parallel to each other, with one end of each rod connected to the rotating assembly 42. The rotating assembly 42 is mounted on the lifting assembly 43, which is mounted on the transmission assembly 41. Adjacent clamping rods 44 are used to clamp the steel pipe 3. The rotating assembly 42 drives the multiple clamping rods 44 to rotate synchronously, and the lifting assembly 43 drives each clamping rod 44 to rise and fall relative to the zinc pot 1. Figure 4 and Figure 5 As shown, the two clamping rods 44 form the clamping structure of the steel pipe 3. In this embodiment, four clamping rods 44 are provided, which can clamp three square and rectangular tubes at the same time to improve work efficiency.

[0045] like Figure 4 As shown, each clamping rod 44 has a clamping slot 441 on one side of its lower end. The inner contour of the clamping slot 441 is adapted to the outer contour of the steel pipe 3. The upper end of the clamping rod 44 is eccentrically installed to the execution end of the rotating component 42 so that the clamping structure of the steel pipe 3 can be opened and closed when the rotating component 42 drives the clamping rod 44 to rotate. A first guide bevel 442 is provided at the inlet end of the clamping slot 441 to facilitate the guidance of the outer periphery of the steel pipe 3 to the clamping slot 441, reduce the influence of the motion tolerance of the transmission components on the clamping operation, and improve the reliability of the device clamping.

[0046] A limiting plate 443 can be detachably installed at the lower end of the clamping rod 44. A clamping slot 441 is provided on one side of the limiting plate 443. The purpose of setting the limiting plate 443 is to facilitate the adjustment of the size of the clamping slot 441. When changing production specifications, only the limiting plate 443 needs to be replaced to adjust the size of the clamping slot 441 that needs to be adapted, thereby improving the convenience of maintenance. A second guide bevel 444 is provided on one or both sides of the lower end of the limiting plate 443.

[0047] like Figure 4 and Figure 6As shown, each clamping rod 44 has a hanging groove 445 on one or both sides, and two adjacent hanging grooves 445 facing each other constitute the hanging structure of the steel pipe 3. The hanging structure is used to limit the relative position of the steel pipe 3 in the zinc pot 1, and the hanging groove 445 is located above the clamping groove 441. The width of the hanging structure is slightly larger than the outer size of the steel pipe 3, so that the outer part of the steel pipe 3 is hung in the hanging structure. By adjusting the relative height of different hanging structures, the relative tilt angle of the steel pipe 3 in the zinc pot 1 can be adjusted to match the upward pulling mechanism to meet the working requirements of the upward pulling mechanism. In addition, a third guide bevel 446 is provided at the inlet end of each hanging groove 445 to facilitate the outer part of the steel pipe 3 to slide into the hanging structure.

[0048] like Figure 7 and Figure 8 As shown, the rotating assembly 42 includes multiple rotating shafts 421 arranged parallel to each other. A clamping rod 44 is eccentrically mounted at one end of each rotating shaft 421, and the other end of each rotating shaft 421 is rotatably connected to a housing 422. A first gear 423 is fixedly sleeved around the periphery of each rotating shaft 421, with adjacent first gears 423 meshing to achieve synchronous rotation of the multiple rotating shafts 421. A first central shaft 425 is rotatably arranged inside the housing 422. One end of the first central shaft 425 is fixedly connected to one end of any rotating shaft 421, or a second gear is fixedly sleeved around the periphery of the first central shaft 425. The second gear meshes with any one of the first gears 423, enabling the first central shaft 425 to synchronously drive the rotation of the multiple rotating shafts 421. A third gear 425 is provided at the other end of the first central shaft 425. 26. The third gear 426 meshes with the first rack 428. One end of the first rack 428 is installed to the actuator of the first linear module 427. The first linear module 427 is a linear motor or hydraulic push rod of the prior art. The first linear module 427 is installed on the first housing 424. The outer periphery of the first central shaft 425 is rotatably connected to the inner ring of the first housing 424. The outer periphery of the first housing 424 is installed on the lifting assembly 43. The movable end of the first linear module 427 can drive the first rack 428 to move linearly along the axial direction. The linearly moving first rack 428 can drive the third gear 426 to rotate, thereby realizing the rotation of the first central shaft 425. That is, the first linear module 427 can drive the rotating shaft 421 to rotate, thereby realizing the opening and closing of the clamping structure and the hanging structure. It requires less power and is easy to control.

[0049] The lifting assembly 43 includes a first motor 431, a fourth gear 432, a second rack 434, and a second housing 433. The first motor 431 is fixedly mounted on the second housing 433. The fourth gear 432 is mounted on the movable end of the first motor 431. The second rack 434 is arranged around the periphery of the first housing 431. The periphery of the fourth gear 432 meshes with one side of the second rack 434. A first slider is provided on the outer wall of the first housing 434, and a first slide rail 435 is provided on the inner wall of the second housing 433. One side of the first slider is slidably connected to the periphery of the first slide rail 435. The second rack 434 and the first slide rail 435 are arranged parallel to each other. The second housing 433 is installed on the transmission assembly 41. The first motor 431 is a servo motor of the prior art. The rotation of the first motor 431 can drive the fourth gear 432 to rotate. The fourth gear 432 meshes with the second rack 434, and the first slider slides relative to the first slide rail 435. This realizes the lifting and lowering of the first housing 424 relative to the second housing 433 driven by the first motor 431, thereby realizing the lifting and lowering of multiple clamping rods 44 in the zinc pot 1 to meet the pressing or lifting action of the steel pipe 3.

[0050] like Figure 7 and Figure 9As shown, the transmission assembly 41 includes a frame 411, a second motor 412, a second central shaft 413, and a slide plate 414. The frame 411 is installed outside the zinc pot 1. The second motor 412 is mounted on the frame 411. The second central shaft 413 is mounted on the movable end of the second motor 412. A slide plate 414 is provided on one side of each second housing 433, and a second slider is mounted on one side of the slide plate 414. A slide table 415 corresponding to the slide plate 414 is provided on the frame 411, and a second slide rail 416 is provided on the slide table 415. One side of the second slider is slidably connected to the periphery of the second slide rail 416. A third rack 417 is slidably mounted on the slide table 415. One side of the slide plate 414 is hinged to one end of the third rack 417. One side of the third rack 417 meshes with the periphery of a fifth gear. The fifth gear is sleeved on the periphery of the second central shaft 413. The second motor 412 is a prior art power motor. Machine 412 can drive multiple clamping units to move synchronously via the second central shaft 413. In this embodiment, two clamping units are arranged along the axial direction of the steel pipe 3. The rotation of the second central shaft 413 can drive two slide plates 414 to slide relative to each other on the slide table 415. Each slide plate 414 is equipped with a clamping unit to reduce the use of power components, reduce equipment costs, and facilitate maintenance. The third rack 417 is hinged to the slide table 415 to reduce the impact of production part tolerances on the device. Two sets of support wheels are rotatably arranged on the second slide table 415. The third rack 417 is located between the two sets of support wheels. Each set of support wheels includes multiple support wheel bodies 418, and the periphery of each support wheel body 418 is fixedly connected to one side of the third rack 417. The two sets of support wheels can limit the sliding trajectory of the third rack 417 and ensure that the third rack 417 can mesh with the fifth gear.

[0051] like Figure 9 As shown, each second housing 433 is provided with a corresponding retractable cantilever 45, and one end of each retractable cantilever 45 is hinged to the second housing 433, and the other end of the retractable cantilever 45 is hinged to the frame 411. The retractable cantilever 45 is used to connect signal lines or pneumatic or hydraulic media pipelines. The retractable cantilever 45 includes at least two arms 451, which are hinged to each other. One end of the arm 451 at the end is hinged to the second housing 433, and one end of the arm 451 at the beginning is hinged to the frame 411. When the first linear module 427 selects a hydraulic push rod as the linear motion power, the hydraulic pipes can be connected in series through the retractable cantilever 45 to prevent the hydraulic pipes from being scattered on the frame 411, which could pose a safety hazard.

[0052] like Figure 2 and Figure 3As shown, multiple material limiting components 2 are arranged along the axial direction of the steel pipe 3 inside the zinc pot 1. The multiple material limiting components 2 are used to limit the relative position of the steel pipe 3 inside the zinc pot 1, and each material limiting component 2 is a U-shaped structure. The outer wall of the U-shaped structure of the material limiting component 2 can be attached to the groove wall of the zinc pot 1, and the bottom inner wall of the U-shaped structure is provided with a limiting groove 21. The number of limiting grooves 21 is at least as many as the number of steel pipes 3 clamped by a single clamping unit, so as to ensure that the periphery of each steel pipe 3 can be limited to the limiting groove 21. The inlet end of the limiting groove 21 is provided with a fourth guide bevel 22 to guide and ensure that the periphery of the steel pipe 3 enters the limiting groove 21.

[0053] A mounting platform 23 is provided on the upper end of the outer wall of the U-shaped structure of the material limiting component 2. The lower end of the mounting platform 23 is attached to the upper side wall of the zinc pot 1. A locking interface 24 is provided on one side of the mounting platform 23. A support rod is sleeved inside the locking interface 24. The outer periphery of the support rod is fixedly connected to the outer periphery of the zinc pot 1. An adjusting nut is locked on each side of the locking interface 24. The inner thread of the adjusting nut is connected to the outer periphery of the support rod. The support rod is used to limit the relative position of the material limiting component 2 in the zinc pot 1. By setting the mounting platform 23, the material limiting component 2 can be installed with rough positioning so that the relative positions of multiple material limiting components 2 can be adjusted during the initial installation. After the adjustment is completed, the relative positions of multiple material limiting components 2 can be fixed by the support rod to prevent the material limiting components 2 from moving during the production process, which would affect the production efficiency and production quality.

[0054] The process of the material transfer mechanism clamping the steel pipe:

[0055] Galvanized steel pipes 3 are stacked at equal intervals on the material conveying mechanism, either mechanically or manually. The second motor 412 drives the second central shaft 413 and the fifth gear to rotate, thereby enabling the third rack 417 to move linearly between the two sets of support wheels. The linearly moving third rack 417 drives the slide plate 414 to slide on the slide table 415, thereby enabling the lifting component 43, the rotating component 42, and multiple clamping rods 44 to be transferred from the zinc pot 1 to the material conveying mechanism. After the second motor 412 rotates a set number of times, it drives the slide plate 414 to move into position. The first linear module 427 in the rotating component 42 drives the first rack 428 to move. The first rack 428 drives the third gear 426, the first central shaft 425, and multiple rotating shafts 421 to rotate synchronously. After the first rack 428 has traveled a set distance and driven the rotating shaft 421 to rotate into position, the clamping structure... When the lifting assembly 43 is opened, it drives the rotating assembly 42 and multiple clamping structures to descend to the set position. The first linear module 427 is reset. At this time, each clamping structure holds a steel pipe 3. After the lifting assembly 43 raises the rotating assembly 42 and multiple clamping structures, the transmission assembly 41 is reset. At this time, the steel pipe 3 is above the zinc pot 1. The lifting assembly 43 drives the rotating assembly 42 and multiple clamping structures to slowly descend to the set position. The descent process is the clamping structure pressing the steel pipe 3 in the zinc liquid. After the steel pipe 3 is above the limiting groove 21, the first linear module 427 moves to control the clamping structure to open. The steel pipe 3 falls into the limiting groove 21 under the guidance of gravity and the fourth guide bevel 22.

[0056] The process of the material transfer mechanism retrieving the galvanized steel pipe:

[0057] The lifting component 43 drives the rotating component 42 and multiple clamping structures to descend to the set position. The first linear module 427 controls the hanging structure to close. At this time, the outer periphery of the steel pipe 3 is located between the two clamping rods 44. The lifting component 43 drives the rotating component 42 and multiple clamping structures to rise. As the hanging structure is raised and guided by the third guide bevel 446, the outer periphery of the galvanized steel pipe 3 gradually falls into the hanging structure. By adjusting different hanging structures through different lifting components 43, the galvanized steel pipe 3 is positioned at a set angle in the zinc pot 1 to match the lead-out angle of the upper guide mechanism.
