Description

Technical Field

[0001] The present invention relates to the technical field of transfer devices, and particularly to a special-shaped pipe galvanizing processing device and method. Background Art

[0002] Galvanizing of special-shaped pipes is an important process to improve their corrosion resistance and extend their service life. By means of hot-dip galvanizing or electroplating, a zinc layer is attached to the surface of the special-shaped pipe. Hot-dip galvanizing is to immerse the special-shaped pipe into molten zinc liquid to form a zinc-iron alloy layer. In the hot-dip galvanizing process, in order to ensure that the special-shaped pipe can fully react with the molten zinc liquid and form a high-quality zinc-iron alloy layer, the preliminary pretreatment work is crucial. First, the special-shaped pipe needs to be degreased to remove the oil and impurities on the surface. This can be achieved by chemical degreasing method, immersing the special-shaped pipe in a degreasing solution containing alkaline substances such as sodium hydroxide and sodium carbonate, and decomposing the oil through chemical reactions and detaching it from the pipe surface. Then, pickling and rust removal are carried out. The pipe is soaked in dilute hydrochloric acid or dilute sulfuric acid to remove the rust and scale on the surface, exposing the fresh metal matrix on the pipe surface. After pickling, water washing and fluxing treatment are required. The fluxing solution usually contains ammonium chloride and zinc chloride, which can form a protective film on the pipe surface, prevent re-oxidation, and promote the combination of zinc liquid and the pipe. Electroplating is to deposit zinc ions on the surface of the special-shaped pipe by electrolysis, which can significantly improve the corrosion resistance, resist the erosion of the external environment, and reduce the chance of rusting; enhance the aesthetics, making the surface of the special-shaped pipe smoother and flatter; improve the mechanical properties, to a certain extent, improve the hardness and wear resistance of the pipe, and is widely used in the construction field, such as building steel structures, curtain wall frames, etc.; in mechanical manufacturing, it can be used as components and transmission devices; it is also used in the transportation industry to manufacture certain parts of automobiles and trains, meeting the requirements for the durability and aesthetics of special-shaped pipes in different scenarios.

[0003] Currently, special-shaped pipes have many depressions, corners and irregular shapes. When hot-dip galvanizing is carried out, when the zinc liquid flows through these parts, the flow rate will significantly slow down, and it is easy to accumulate in these places, forming a relatively thick zinc layer. If the zinc liquid accumulates too thickly, the coating structure will be uneven, and internal stress may be generated, resulting in cracks in the coating. Therefore, a special-shaped pipe galvanizing processing device and method are proposed. Summary of the Invention

[0019] S2. Galvanizing treatment: Clamp both ends of the special-shaped pipe above the galvanizing tank through the support assembly.

Detailed implementation mode

[0037] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0038] Embodiment 1

[0039] Please refer to Figure 1 - Figure 11 , the present invention provides a technical solution: a special-shaped pipe galvanizing processing device, including a mounting plate 1, a galvanizing box 2 is arranged on the side of the mounting plate 1, a support frame 3 is fixedly installed at the bottom of the galvanizing box 2, a first motor 4 is fixedly installed on the side of the mounting plate 1, a water inlet pipe 5 is communicated with the side of the galvanizing box 2, a water outlet pipe 6 is communicated with the bottom of the galvanizing box 2, a galvanizing component 10 and a shaking component 20 are arranged on the side of the mounting plate 1, the galvanizing component 10 and the shaking component 20 are used in cooperation, and a supporting component 30 is arranged above the galvanizing box 2;

[0040] The galvanizing component 10 is used to drive the special-shaped pipe to immerse into the galvanizing box 2;

[0041] The shaking component 20 is used to shake off the excess zinc liquid on the special-shaped pipe;

[0042] The supporting component 30 is used to clamp the special-shaped pipe.

[0043] As a further limitation of the galvanizing component 10 of the present invention, please refer to Figure 1 - Figure 4, the galvanizing component 10 includes a drive shaft 101 rotatably connected to the side of the mounting plate 1. A drive gear 102 is fixedly sleeved on the outer side of the drive shaft 101. A wedge groove plate 103 is fixedly connected to the side of the mounting plate 1. A rack plate 104 is slidably mounted on the side of the mounting plate 1. A wedge block 105 is fixedly connected to the side of the rack plate 104. The wedge block 105 is slidably connected inside the wedge groove plate 103. The drive gear 102 is in meshing transmission with the rack plate 104. An installation frame 209 is fixedly connected to the rack plate 104. A second motor 208 is fixedly connected to the installation frame 209. When the drive shaft 101 drives the drive gear 102 to rotate, the rack plate 104 meshing with the drive gear 102 will slide linearly along a specific direction, meeting the requirement of the component for linear motion in practical applications. The meshing transmission has a high transmission efficiency, which can effectively reduce the loss of energy during transmission, ensuring that power can be stably and efficiently transmitted from the drive shaft 101 to the rack plate 104, making the operation of the entire galvanizing component 10 smoother.

[0044] The specific implementation manner of this embodiment is as follows: The operator clamps the wall of the special-shaped pipe inside the support component 30. Then, the prepared zinc liquid is slowly poured into the galvanizing tank 2. The first motor 4 is started, and the output shaft of the first motor 4 starts to rotate, driving the connected drive shaft 101 to rotate synchronously. The drive gear 102 on the outer side of the drive shaft 101 rotates with the rotation of the drive shaft 101. An effective meshing transmission relationship is formed between the drive gear 102 and the rack plate 104. Under this transmission effect, the rack plate 104 starts to move downward, thereby driving the special-shaped pipe clamped in the support component 30 to gradually immerse into the zinc liquid inside the galvanizing tank 2 and start galvanizing.

[0045] Embodiment 2

[0046] Please refer to Figure 3 - Figure 5 , the present invention provides a technical solution: a special-shaped pipe galvanizing processing device, and the present invention makes corresponding improvements to the technical problems mentioned in the background art.

[0047] As a further limitation of the jitter component 20 of the present invention, the jitter component 20 includes a rotating shaft 201 rotatably connected to the side of the rack plate 104. The output shaft of the second motor 208 penetrates the inside of the mounting frame 209, and the rotating shaft 201 is fixedly connected to the end of the output shaft of the second motor 208. A rotating gear 202 is fixedly sleeved on the outside of the rotating shaft 201. A sliding ring 203 is slidably arranged on the side of the rack plate 104. A limiting groove 204 is opened on the side of the rack plate 104. A limiting block 205 is fixedly connected to the side of the sliding ring 203. The limiting block 205 is slidably engaged with the limiting groove 204. A plurality of teeth 206 are fixedly connected to the inner wall of the sliding ring 203. The rotating gear 202 is meshed with the plurality of teeth 206 for transmission. A prolonging plate 207 is also fixedly connected to the side of the rack plate 104. The second motor 208 drives the rotating shaft 201 to rotate. The rotating shaft 201 drives the rotating gear 202 to rotate. The rotating gear 202 is meshed with the teeth 206 on the inner wall of the sliding ring 203 for transmission. The forward and reverse rotations of the second motor 208 convert the circular motion into the reciprocating motion of the sliding ring 203 on the rack plate 104. Due to the sliding engagement between the limiting block 205 and the limiting groove 204, it is ensured that the sliding ring 203 can only slide stably along the rack plate 104. It can make the galvanized liquid adhere to the surface of the workpiece more evenly, avoid local accumulation or formation of flow marks of the galvanized liquid, thereby improving the quality and effect of galvanizing, making the galvanized layer of the workpiece more uniform and dense, and enhancing the corrosion resistance of the workpiece.

[0048] A plurality of threaded holes 301 are provided at the bottom of the prolonging plate 207. A support block 302 is detachably installed at the bottom of the prolonging plate 207. A bolt 303 is threadedly connected between the support block 302 and the prolonging plate 207. A sliding block 304 is fixedly connected to the bottom of the support block 302. A fixed block 305 is arranged at the bottom of the sliding block 304. The sliding block 304 is slidably connected to the inside of the fixed block 305. A track column 306 is fixedly connected to the side of the fixed block 305. A track groove 307 is opened on the side of the rack plate 104. The track column 306 is slidably connected to the inside of the track groove 307. An L-shaped block 308 is fixedly connected to the side of the fixed block 305. By changing the moving speed and position of the track column 306 in the track groove 307, the frequency and amplitude of jitter can be flexibly adjusted.

[0049] The specific implementation manner of this embodiment is as follows: Start the second motor 208, and the second motor 208 drives the rotating shaft 201 and the rotating gear 202 outside it to rotate synchronously. The rotating gear 202 forms intermittent meshing with the teeth 206 on the inner wall of the sliding ring 203, thereby driving the support assembly 30 to move horizontally. At the same time, the track column 306 on the side of the fixed block 305 slides in the track groove 307. Due to the setting of the track groove 307, during the process of the L-shaped block 308 driving the support assembly 30 to move horizontally, the track column 306 and the track groove 307 are slidingly engaged, and the sliding block 304 slides and engages inside the fixed block 305, enabling the support assembly 30 to achieve slight up-and-down shaking. This shaking helps to shake off the residual zinc liquid on the special-shaped pipe;

[0050] It should be noted that the reciprocating distance of the sliding ring 203 is relatively small and will not get stuck with the mounting frame 209.

[0051] Embodiment Three

[0052] Please refer to Figures 6 - 10 , the present invention provides a technical solution: a special-shaped pipe galvanizing processing device, and the present invention makes corresponding improvements to the technical problems mentioned in the background art.

[0053] As a further limitation of the support assembly 30 of the present invention, the support assembly 30 includes a support column 309 arranged on the side of the L-shaped block 308. A fixed disk 310 is fixedly sleeved outside the support column 309. A plurality of connecting columns 317 are also fixedly connected to the side of the L-shaped block 308. The ends of the plurality of connecting columns 317 are connected to a connecting disk 319. A rotating frame 311 is fixedly connected to the side of the connecting disk 319. A T-shaped plate 312 is slidably connected to the side of the rotating frame 311. An arc-shaped groove 313 is opened on the side of the fixed disk 310.

[0054] A moving column 314 is fixedly connected to the side of the T-shaped plate 312. The moving column 314 is slidably engaged with the inside of the arc-shaped groove 313. A limit disk 315 is connected to the end of the moving column 314. A sliding notch 316 is opened on the side of the rotating frame 311. The moving column 314 is slidably engaged with the sliding notch 316. A third motor 318 is fixedly installed inside the L-shaped block 308. The output shaft of the third motor 318 is fixedly connected to the end of the support column 309. Clamping from the outside may leave marks, imprints and other damages on the surface of the pipe body, affecting its surface finish and aesthetics, while clamping from the inside can avoid direct contact with the outer surface of the special-shaped pipe and will not damage its appearance. The sliding fit of the moving column 314 in the sliding notch 316 increases the flexibility of the structure. It allows the T-shaped plate 312 to move freely within a certain range, so as to adapt to different pipe diameters and pipe openings;

[0055] Only the moving column 314 on the side of the T-shaped plate 312 is slidably engaged with the arc-shaped groove 313 on the side of the fixed disk 310.

[0056] The specific implementation method of this embodiment is as follows: Before galvanizing, preliminary preparation work needs to be carried out. First, the T-shaped plate 312 is clamped at the pipe orifice of the special-shaped pipe. Subsequently, the third motor 318 is started. After the third motor 318 is started, its output shaft quickly starts to rotate, driving the supporting column 309 connected thereto to rotate synchronously, and then driving the fixed disk 310 to rotate. As the fixed disk 310 rotates, the moving column 314 installed on its side starts to slide in the arc-shaped groove 313. Under the acting force of the moving column 314 sliding along the arc-shaped groove 313, the T-shaped plate 312 originally located inside the rotating frame 311 is driven to protrude outward. The protruding T-shaped plate 312 firmly abuts against the inner wall of the special-shaped pipe, ensuring that the special-shaped pipe can maintain a stable state during the subsequent galvanizing process, so as to obtain a uniform and high-quality galvanizing effect;

[0057] It should be noted that the end of the T-shaped plate 312 is made of a high-friction material, which can better extrude the wall of the special-shaped pipe.

[0058] A method for galvanizing a special-shaped pipe specifically includes the following steps:

[0059] S1. Pretreatment module: Equipped with an acid pickling tank, a solvent cleaning device, and a preheating furnace, which are used to remove oil stains, oxide scales, and rust on the surface of the pipe, and improve the processing adaptability of the material through preheating treatment;

[0060] S2. Galvanizing treatment: The two ends of the special-shaped pipe are clamped above the galvanizing tank 2 through the supporting component 30. The servo motor drives the special-shaped pipe to immerse into the interior of the galvanizing tank 2 through the galvanizing component 10, and then drives the special-shaped pipe to shake through the shaking component 20 to drop the excess zinc liquid;

[0061] S3. Post-galvanizing treatment and inspection: When cooling the special-shaped pipe, first air-cool it to below 200 °C, then water-cool it to room temperature for stabilization, and then remove the zinc nodules through polishing.

[0062] It should be noted that in this article, relational terms such as first and second are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any actual relationship or order between these entities or operations. Moreover, the term "comprising", "including" or any other variant thereof is intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements not only includes those elements, but also includes other elements not expressly listed, or also includes elements inherent to such process, method, article or device.

[0063] Although embodiments of the present invention have been shown and described, it will be understood by those of ordinary skill in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
