Description

Technical Field

[0001] This invention relates to the field of PE gas pipe processing technology, and in particular to a heat treatment device for PE gas pipe processing. Background Technology

[0002] PE gas pipes are gas transmission pipelines made of polyethylene. They have advantages such as corrosion resistance, good flexibility, and long service life, and are widely used in the gas transmission field. Heat treatment is an important process in the manufacturing of PE gas pipes. Heat treatment can eliminate internal stress in the pipe material and improve its mechanical properties and stability.

[0003] Currently, existing PE gas pipe heat treatment devices suffer from uneven heating during use, which can easily lead to localized overheating or underheating of the pipe, affecting the heat treatment effect. Summary of the Invention

[0004] This application discloses a heat treatment device for processing PE gas pipes to solve the problem of uneven heating in the prior art.

[0005] To solve the above problems, the present invention adopts the following technical solution:

[0006] A heat treatment apparatus for processing PE gas pipes, comprising:

[0007] Heat treatment chamber, used for heat treatment of pipes;

[0008] Rotating mechanisms are provided on both sides of the heat treatment chamber. These mechanisms can be used to clamp the pipe and rotate it so that the pipe is heated evenly in the heat treatment chamber.

[0009] The technical solution adopted in this invention can achieve the following beneficial effects:

[0010] This invention provides the necessary temperature environment for pipe heat treatment through a heat treatment chamber, causing physical or chemical changes in the pipe under specific temperature conditions to meet usage requirements. The rotating mechanism of this invention has the functions of clamping and rotating the pipe. By driving the pipe to rotate through the rotating mechanism, all parts of the pipe surface can fully contact the heat in the heat treatment chamber, avoiding local overheating or undercooling, thus ensuring uniform heating of the pipe, improving heat treatment quality, and making the pipe performance more stable and consistent. Uniform heating also helps reduce pipe deformation caused by uneven temperature, thereby improving the processing accuracy of the pipe and making its dimensions more in line with standard requirements, which is beneficial for subsequent connection and use. Furthermore, the clamping function of the rotating mechanism can adapt to pipes of different diameters. By adjusting the clamping force and rotation parameters, various specifications of pipes can be heat treated, increasing the applicability of the device. The rotating mechanism allows one section of the pipe to rotate in the heat treatment chamber, achieving uniform heating of the pipe and avoiding local overheating or underheating, which would affect the heat treatment effect.

[0027] To make the objectives, technical solutions, and advantages of this invention clearer, the technical solutions of this invention will be described in detail below. Obviously, the described embodiments are merely some embodiments of this invention, and not all embodiments. Based on the embodiments of this invention, all other implementation methods obtained by those skilled in the art without creative effort are within the scope of protection of this invention.

[0028] The terms "first," "second," "third," etc., used in the specification and claims of this application are used to distinguish similar objects and not to describe a specific order or sequence. It should be understood that such data can be interchanged where appropriate so that embodiments of this application can be implemented in orders other than those illustrated or described herein, and the objects distinguished by "first," "second," "third," etc., are generally of the same class and the number of objects is not limited; for example, a first object can be one or more. Furthermore, in the specification and claims, "and / or" indicates at least one of the connected objects, and the character " / " generally indicates that the preceding and following objects are in an "or" relationship.

[0029] The inventive concept of this application is described here:

[0030] During practical use, the inventors discovered several shortcomings of existing PE gas pipe heat treatment devices. First, during the heating process, the high-temperature region of the pipe near the heating point heats up too quickly, while the low-temperature region heats up insufficiently, easily leading to localized overheating or underheating. This uneven heating results in significant inconsistencies in the internal structure and properties of the pipe after heat treatment, greatly reducing product quality and reliability. Second, PE gas pipes come in various sizes, and existing heat treatment devices require recalibration when handling different types, making them cumbersome. Furthermore, cooling is necessary after heat treatment, but current methods typically involve natural cooling, which is slow and uneven, reducing production efficiency and affecting pipe quality.

[0031] Based on this, the inventor provides a heat treatment device for processing PE gas pipes, which can achieve uniform heating of PE gas pipes, avoid local overheating or undercooling, improve heat treatment quality, and make the performance of PE gas pipes more stable and consistent. It can also be adjusted according to different sizes of PE gas pipes, so that the heat treatment device can adapt to different sizes of PE gas pipes without recalibrating the heat treatment device, which is simple and convenient. In addition, it can uniformly cool the PE gas pipes after heat treatment, which improves production efficiency and reduces quality risks.

[0032] The following is in conjunction with the appendix Figures 1 to 9 The present application provides a detailed description of a heat treatment apparatus for processing PE gas pipes through specific embodiments and application scenarios.

[0033] Reference Figure 1 and Figure 2 A heat treatment device for processing PE gas pipes includes: a heat treatment box 100 and a rotating mechanism 200;

[0034] Specifically, refer to Figure 1and Figure 2 The heat treatment apparatus also includes a base 10, and the heat treatment box 100 and the rotating mechanism 200 are all mounted on the base 10.

[0035] The heat treatment chamber 100 is used for heat treatment of pipes;

[0036] It should be noted that the pipe used in this embodiment is a PE gas pipe, and the same applies below.

[0037] Specifically, refer to Figure 1 and Figure 2 A boss is installed in the middle of the top of the base 10, and the heat treatment box 100 is installed on the boss. The heat treatment box 100 provides the required temperature environment for the heat treatment of the pipe, so that the pipe undergoes physical or chemical changes under specific temperature conditions to meet the usage requirements.

[0038] The heat treatment chamber 100 is equipped with a rotating mechanism 200 on both sides. The rotating mechanism 200 can be used to clamp the pipe and rotate the pipe so that the pipe is heated evenly in the heat treatment chamber 100.

[0039] Specifically, there are two sets of rotating mechanisms 200, located on both sides of the heat treatment box 100, and both sets of rotating mechanisms 200 are located on the top of the base 10; the rotating mechanism 200 has the function of clamping and rotating the tube.

[0040] By rotating the pipe through the rotating mechanism 200, all parts of the pipe surface can fully contact the heat in the heat treatment chamber 100, avoiding local overheating or undercooling. This ensures uniform heating of the pipe, improves the quality of heat treatment, and makes the performance of the pipe more stable and consistent. Uniform heating also helps reduce pipe deformation caused by uneven temperature, thereby improving the processing accuracy of the pipe and making its dimensions more in line with standard requirements. This is beneficial for subsequent connection and use. Furthermore, the clamping function of the rotating mechanism 200 can adapt to pipes of different diameters. By adjusting the clamping force and rotation parameters, it can perform heat treatment on pipes of various specifications, increasing the applicability of the device.

[0041] Among them, reference Figure 2 , Figure 3 and Figure 8 In this embodiment, an inlet and an outlet are respectively provided on both sides of the heat treatment box 100, and a reflector 110 is installed inside the heat treatment box 100. Multiple heating tubes 120 are installed inside the reflector 110.

[0042] Specifically, refer to Figure 2 , Figure 3 and Figure 8Two sets of rotating mechanisms 200 are located at the inlet and outlet of the heat treatment chamber 100, respectively. Rubber curtains 130 are provided at both the inlet and outlet of the heat treatment chamber 100. By providing rubber curtains 130, the heat overflow in the heat treatment chamber 100 is reduced, thereby improving the heat treatment effect. A reflector 110 is installed on the inner top of the heat treatment chamber 100 and is arc-shaped. Multiple heating tubes 120 are evenly installed inside the reflector 110 through an arc-shaped connecting frame.

[0043] The pipe enters the heat treatment chamber 100 through the inlet and exits the heat treatment chamber 100 through the outlet of the reflector 110.

[0044] Specifically, the pipe enters the heat treatment chamber 100 from the inlet, passes through the heating area formed by the reflector 110 and the heating tube 120, and is then output from the outlet of the heat treatment chamber 100.

[0045] The inlet and outlet of the heat treatment chamber 100 allow the pipes to continuously enter and exit the heat treatment chamber 100. With the clamping and conveying function of the rotating mechanism 200, a section of the pipe is heated, and after heat treatment, the heated section is conveyed so that the subsequent sections of the pipe awaiting heat treatment can enter the heat treatment chamber 100 for heat treatment. This enables a "feed-heating-discharge" assembly line operation, avoiding the waiting time of traditional batch processing and greatly improving production efficiency. The specific structure and working principle of the reflector 110 and the heating tube 120 are common knowledge, so they will not be described in detail here.

[0046] The reflector 110 is used to evenly irradiate the heat generated by the heating tube 120 onto the tube.

[0047] Specifically, the heating tube 120 generates heat as a heat source, while the reflector 110 guides and evenly distributes the heat on the surface of the tube. The design of the reflector 110 can reflect and concentrate the heat generated by the heating tube 120, preventing the heat from spreading randomly in all directions and making the heat more concentrated on the surface of the tube. At the same time, in conjunction with the rotating mechanism 200 to drive the tube to rotate, it achieves the dual guarantee of "uniform heat irradiation + tube rotation heating", completely solving the problem of local temperature difference and ensuring the overall performance of the tube is consistent. The reflector 110 reduces the loss of heat to the non-working area of ​​the heat treatment box 100, and in conjunction with the rubber curtain 130, it allows more of the energy generated by the heating tube 120 to be used for heating the tube, improving the heat utilization efficiency.

[0048] The heat treatment chamber 100, through the combined design of reflector 110, heating tube 120 and rubber curtain 130, provides a stable heat source while maximizing heat utilization efficiency and heating uniformity. Together with the rotating mechanism 200, it forms a complete heat treatment process of "uniform heating + continuous conveying", further optimizing the practicality, energy saving and production efficiency of the device.

[0049] Reference Figure 1 and Figure 2 In this embodiment, the heat treatment apparatus further includes a first conveying mechanism 300 and a second conveying mechanism 400. The first conveying mechanism 300 and the second conveying mechanism 400 have the same structure. The first conveying mechanism 300 is close to the inlet of the heat treatment box 100, and the second conveying mechanism 400 is close to the outlet of the heat treatment box 100. Both the first conveying mechanism 300 and the second conveying mechanism 400 are used to convey pipes.

[0050] Specifically, the base 10 is located between the first conveying mechanism 300 and the second conveying mechanism 400; the first conveying mechanism 300 is responsible for feeding the pipes to be processed into the inlet of the heat treatment chamber 100, and the second conveying mechanism 400 is responsible for sending the heat-treated pipes out from the outlet; by having the first conveying mechanism 300 near the inlet of the heat treatment chamber 100 and the second conveying mechanism 400 near the outlet of the heat treatment chamber 100, a continuous layout of "inlet conveying - heat treatment - outlet conveying" is formed, realizing fully automated conveying, greatly reducing the waiting time between processes, and significantly improving production efficiency; the first conveying mechanism 300 and The second conveying mechanism 400 has the same structure, which facilitates standardized design, manufacturing and installation, reduces the types of parts, and at the same time, the unified structure allows maintenance personnel to master only one maintenance method, reducing the complexity and cost of equipment maintenance. The first conveying mechanism 300 and the second conveying mechanism 400 can be connected with the upstream and downstream production equipment (such as pipe feeding racks and finished product collection devices) to form a large-scale production line. By adjusting the conveying speed, it can also be matched with the heating efficiency of the heat treatment box 100 and the rotation speed of the rotating mechanism 200, flexibly adapting to different production needs and improving the adaptability and scalability of the device in industrial production.

[0051] Reference Figure 1 , Figure 2 and Figure 9 The first conveying mechanism 300 and the second conveying mechanism 400 can be roller conveyors. Specifically, the first conveying mechanism 300 includes a first conveyor frame 320, on which a plurality of first rollers 330 are rotatably connected. The plurality of first rollers 330 are connected to each other by a gear chain (not shown in the figure), and one of the first rollers 330 is driven by a motor. The second conveying mechanism 400 includes a second conveyor frame 410, on which a plurality of second rollers 420 are rotatably connected. The plurality of second rollers 420 are connected to each other by a gear chain (not shown in the figure), and one of the second rollers 420 is driven by a motor. The working principles of the first conveying mechanism 300 and the second conveying mechanism 400 are common knowledge, and therefore will not be described in detail here.

[0052] Reference Figure 1, Figure 2 and Figure 9 In this embodiment, limit components 310 are connected to both sides of the width direction of the first conveying mechanism 300. The limit components 310 are used to limit the pipe material during the conveying process.

[0053] Specifically, there are two sets of limiting components 310, which are located on both sides of the width direction of the first conveying mechanism 300. By limiting the rolling deviation of the pipe during the conveying process, the limiting components 310 ensure that the pipe moves stably along the preset path, ensuring that the pipe can be accurately aligned with the inlet of the heat treatment box 100, smoothly enter the box and be accurately clamped by the rotating mechanism 200. This avoids problems such as jamming and docking failure caused by pipe deviation, ensuring a smooth connection of the "conveying-heat treatment" link, and preventing the pipe from colliding with the edge of the first conveyor frame 320 or other components during the conveying process, protecting the appearance and structural integrity of the pipe. Furthermore, the automatic constraint function of the limiting components 310 reduces the necessity of manually adjusting the position of the pipe, making the conveying process more fully automated.

[0054] Reference Figure 9 In this embodiment, the limiting component 310 includes a second telescopic member 311 and a limiting plate 312;

[0055] The second telescopic member 311 is connected to the first conveying mechanism 300, and a limit plate 312 is connected to the telescopic end of the second telescopic member 311.

[0056] Specifically, the second telescopic member 311 is a cylinder, a hydraulic cylinder or an electric cylinder. In this embodiment, the second telescopic member 311 is preferably a cylinder. Its specific structure and working principle are common knowledge, so they will not be described in detail here. The limiting plate 312 is located above the first roller 330, and the length direction of the limiting plate 312 is the same as the length direction of the first conveyor frame 320.

[0057] The two sets of limiting components 310 also include mounting plates 313 symmetrically installed on both sides of the first conveyor frame 320 in the width direction. A second telescopic member 311 is installed on the side of the mounting plate 313 away from the first roller 330. The second telescopic member 311 is horizontally arranged. The telescopic end of the second telescopic member 311 passes through the mounting plate 313 and is connected to the limiting plate 312. The telescopic end of the second telescopic member 311 is slidably connected to the mounting plate 313. At least one guide rod 314 is slidably arranged on the mounting plate 313 and is parallel to the second telescopic member 311. Specifically, there are two guide rods 314, which are symmetrically arranged on both sides of the second telescopic member 311. One end of the guide rod 314 is connected to the limiting plate 312. The setting of the guide rod 314 makes the movement of the limiting plate 312 more stable.

[0058] The second telescopic component 311 is used to adjust according to different pipe sizes so that the limiting plate 312 can limit the pipe during the conveying process.

[0059] Specifically, the second telescopic member 311 is adjusted to accommodate pipes of different diameters. The limiting plate 312 directly contacts the side of the pipe (or maintains a small gap) to constrain the rolling deviation of the pipe during transportation. An elastic pad (not shown in the figure) can be set on the opposite side of the two limiting plates 312 to reduce hard contact and friction with the surface of the pipe during limiting, avoid scratching the outer surface of the pipe, and ensure the appearance quality of the product.

[0060] Reference Figure 2 , Figures 4 to 7 In this embodiment, the rotating mechanism 200 includes a driving component 210 and a clamping component 220;

[0061] The drive assembly 210 is connected to multiple clamping assemblies 220;

[0062] The drive assembly 210 is used to drive multiple clamping assemblies 220 to rotate, so as to rotate the pipe;

[0063] Specifically, the drive component 210 serves as a power source, responsible for driving the multiple clamping components 220 connected to it to rotate as a whole, thereby achieving the rotation of the pipe through the rotation of the clamping components 220.

[0064] The clamping assembly 220 can be used to clamp the pipe.

[0065] Specifically, the clamping assembly 220 directly contacts the pipe, serving to clamp and fix the pipe, ensuring that the pipe does not loosen or shift during rotation.

[0066] Reference Figure 5 and Figure 7 In this embodiment, the drive assembly 210 includes an external gear ring 211, a gear 212, and a limiting part 213;

[0067] Gears 212 are meshed on both sides of the lower part of the external gear ring 211. At least one side of the lower part of the external gear ring 211 is provided with a limiting part 213. Multiple clamping components 220 are connected to the interior of the external gear ring 211 along its circumference.

[0068] Specifically, when gear 212 rotates, it drives the outer gear ring 211 to rotate through meshing. The rotation of the outer gear ring 211 synchronously drives the multiple clamping components 220 connected inside it to rotate, ultimately realizing the rotation of the pipe. The limiting part 213 constrains the movement trajectory of the outer gear ring 211 during its rotation, ensuring the stability of the rotation trajectory.

[0069] In some embodiments, a limiting portion 213 is provided on one lower side of the external gear ring 211.

[0070] In some embodiments, the lower two sides of the external gear ring 211 are provided with limiting portions 213, and this embodiment adopts such a structure.

[0071] Reference Figure 1 , Figure 5 and Figure 7 The drive assembly 210 also includes a motor support mounted on the top of the base 10. A drive component 214 is mounted on the motor support. The drive component 214 is preferably a servo motor. The output end of the drive component 214 is connected to a transmission shaft 215. The transmission shaft 215 is connected to a gear 212, so that the drive component 214 can drive the gear 212 to rotate through the transmission shaft 215. The two sides of the gear 212 can be rotatably connected to the first mounting bracket 216. The first mounting bracket 216 is mounted on the top of the base 10 and supports the gear 212. The transmission shaft 215 passes through the first mounting bracket 216 and is rotatably connected to the first mounting bracket 216. In this embodiment, there are two drive components 214.

[0072] Gear 212 is used to drive the external gear ring 211 to rotate, and to drive multiple clamping assemblies 220 to rotate;

[0073] Specifically, in a set of drive components 210, by driving one gear 212 to rotate, the outer gear ring 211 rotates, and the other gear 212 follows. The meshing transmission structure of the outer gear ring 211 and the gear 212 has higher transmission accuracy and less power loss compared with belt, chain and other transmission methods, and can realize uniform rotation of the pipe.

[0074] The limiting part 213 is used to limit the rotation of the external gear ring 211 so that the external gear ring 211 rotates smoothly.

[0075] Specifically, by limiting the rotation trajectory of the external gear ring 211 through the limiting part 213, the external gear ring 211 can be prevented from shaking or shifting due to uneven force, ensuring that the heating time of each part of the pipe is consistent and further improving the heating uniformity.

[0076] Reference Figure 4 , Figure 5 and Figure 7The limiting part 213 includes a limiting groove 2131 formed on the side of the outer gear ring 211. The limiting groove 2131 is arranged in a ring shape. Multiple sliding wheels 2132 are slidably connected in the lower part of the limiting groove 2131. In this embodiment, there are 3 sliding wheels 2132. The connecting shaft of the sliding wheel 2132 is rotatably connected to the second mounting bracket 2133. The second mounting bracket 2133 is connected to the top of the base 10. The sliding wheel 2132 is supported by the second mounting bracket 2133. The sliding engagement between the sliding wheel 2132 and the limiting groove 2131 limits the rotation of the outer gear ring 211, thereby improving the stability of the rotation of the outer gear ring 211.

[0077] Reference Figure 2 , Figures 4 to 6 In this embodiment, the clamping assembly 220 includes a first telescopic member 221, a clamping plate 222, and a rolling part 223;

[0078] The first telescopic member 221 is connected to the inside of the outer gear ring 211. A clamping plate 222 is connected to the telescopic end of the first telescopic member 221. A rolling part 223 is elastically connected inside the clamping plate 222.

[0079] Specifically, the first telescopic member 221 is a cylinder, a hydraulic cylinder, or an electric cylinder. In this embodiment, the first telescopic member 221 is preferably an electric cylinder. Its specific structure and working principle are common knowledge, so they will not be described in detail here. The clamping plate 222 can be arranged in an arc shape, and a rubber pad (not shown in the figure) is provided on the side of the clamping plate 222 away from the first telescopic member 221. This increases the clamping force of the clamping plate 222 while avoiding hard contact between the clamping plate 222 and the surface of the pipe, thus preventing damage to the surface of the pipe.

[0080] The first telescopic component 221 is used to adjust according to different pipe sizes so that the clamping plate 222 can clamp the pipe.

[0081] Specifically, the first telescopic member 221 is adjusted to accommodate pipes of different diameters, ensuring that the clamping plate 222 can stably clamp the pipe.

[0082] The rolling part 223 is used to improve the stability of pipe transportation.

[0083] Specifically, when the pipe needs to be transported, the first telescopic member 221 can retract slightly, so that the clamping plate 222 separates from the pipe. The rolling part 223 extends out of the moving groove 2231 under the elastic action and contacts the surface of the pipe, which facilitates the transport of the pipe and improves the stability of the pipe transport. Moreover, due to the elastic connection, when the clamping plate 222 clamps the pipe, the rolling part 223 retracts into the clamping plate 222, which can reduce the hard contact with the surface of the pipe during clamping, reduce the risk of scratches, indentations and other damage, and ensure the appearance and structural integrity of the pipe.

[0084] Reference Figure 6 In this embodiment, the rolling part 223 includes a moving groove 2231, a connecting plate 2232, and a rolling element 2233;

[0085] A movable groove 2231 is provided on the clamping plate 222, and a connecting plate 2232 is slidably arranged in the movable groove 2231. Multiple rolling elements 2233 are rotatably connected to the connecting plate 2232.

[0086] Specifically, the connecting plate 2232 can be arc-shaped. Through the sliding cooperation between the connecting plate 2232 and the moving groove 2231, the rolling element 2233 can extend or retract into the moving groove 2231. The arc-shaped surface of the connecting plate 2232 can match the arc-shaped surface of the clamping plate 222, that is, the connecting plate 2232 is always in the moving groove 2231 and will not completely detach from the moving groove 2231; the rolling element 2233 is preferably a ball bearing.

[0087] Reference Figure 6 The telescopic end of the first telescopic member 221 has a sliding groove 224 that communicates with the moving groove 2231. A slider 225 is slidably disposed in the sliding groove 224. A connecting rod 226 is installed on the slider 225. The other end of the connecting rod 226 is connected to the connecting plate 2232. An elastic element 227 is sleeved on the outer surface of the connecting rod 226 between the slider 225 and the inner wall of the sliding groove 224. The elastic element 227 is preferably a spring. The setting of the elastic element 227 allows the connecting plate 2232 to slide in the moving groove 2231.

[0088] Rolling element 2233 is used to improve the stability of pipe transportation.

[0089] Specifically, when the pipe needs to be clamped, the extension of the first telescopic member 221 causes the clamping plate 222 to clamp the pipe. Under the action of the elastic member 227, the rolling member 2233 retracts into the moving groove 2231. When the pipe needs to be transported, the retraction of the first telescopic member 221 causes the clamping plate 222 to separate from the pipe. Under the action of the elastic member 227, the rolling member 2233 extends out of the moving groove 2231 to achieve rolling support with the pipe and improve the stability of the pipe during transport.

[0090] Reference Figure 7 In this embodiment, a plurality of cooling elements 230 are connected circumferentially inside the external gear ring 211 located at the outlet of the heat treatment chamber 100. The cooling elements 230 are used to cool the heat-treated pipe.

[0091] Specifically, the cooling component 230 is preferably a fan, the specific structure and working principle of which are common knowledge and will not be described in detail here. The cooling component 230 rotates synchronously with the external gear ring 211 to uniformly cool the pipe, which can avoid problems such as uneven internal stress and deformation caused by localized excessively fast or slow cooling of the pipe. Combined with the rotation of the pipe itself, it further improves the uniformity of cooling, reduces quality defects such as cracking and bending, and the process of heating and cooling the pipe is continuous, avoiding temperature fluctuations in intermediate transfer links, ensuring the continuity and stability of the heat treatment process, and helping the pipe to obtain the expected mechanical properties.

[0092] Reference Figure 2 , Figure 5 and Figure 7 In this embodiment, four clamping components 220 are connected circumferentially inside the outer gear ring 211 located at the inlet of the heat treatment chamber 100, and two clamping components 220 and two cooling components 230 are connected circumferentially inside the outer gear ring 211 located at the outlet of the heat treatment chamber 100. The clamping components 220 and the cooling components 230 are arranged alternately.

[0093] In this embodiment, an electrical control cabinet is provided on one side of the base 10. The electrical control cabinet contains various electrical components, system programs, operation panels, etc., which control the entire device to perform actions according to a predetermined program, process various sensors and signal sources, and output corresponding program instructions. Operators can input the data of the pipe into the system program through an external touch screen. At the same time, external indicator lights and alarm lights display the operating status of the device, and external buttons can pause or stop the operation of the device.

[0094] Working principle: In use, depending on the diameter of the pipe, the distance of the limiting plate 312 is adjusted by the second telescopic member 311. The pipe is conveyed by the first conveying mechanism 300. After the pipe passes through the external gear ring 211 at the inlet of the heat treatment box 100, it enters the heat treatment box 100. The first conveying mechanism 300 stops conveying. The extension of the first telescopic member 221 causes the clamping plate 222 to clamp the pipe. Under the action of the elastic member 227, the rolling member 2233 retracts into the moving groove 2231. The drive member 214 drives the transmission shaft 215 to rotate, thereby driving the gear 212 to rotate, which in turn drives the external gear ring 211 to rotate. Thus, the clamping plate 222 drives the pipe to rotate, so that all parts of the pipe surface can fully contact the heat inside the heat treatment box 100.

[0095] After a section of pipe in the heat treatment chamber 100 undergoes heat treatment, the retraction of the first telescopic member 221 separates the clamping plate 222 from the pipe. Under the action of the elastic member 227, the rolling member 2233 extends out of the moving groove 2231 to achieve rolling support with the pipe. The first conveying mechanism 300 continues to convey the pipe. The heat-treated section of the pipe exits from the outlet of the heat treatment chamber 100, passes through the external gear ring 211 at the outlet of the heat treatment chamber 100, and enters the second conveying mechanism 400. Then, the first telescopic member 221 at the inlet of the heat treatment chamber 100 extends, causing the clamping plate 222 to clamp the pipe. The first telescopic member 223 at the outlet of the heat treatment chamber 100 extends. The telescopic component 221 extends, causing the rolling component 2233 to contact the pipe, while the clamping plate 222 does not contact the pipe. Then, the drive component 214 at the inlet of the heat treatment chamber 100 drives the transmission shaft 215 to rotate, ultimately causing the pipe to rotate. The drive component 214 at the outlet of the heat treatment chamber 100 is not activated, while the cooling component 230 is activated. During the rotation of the pipe, one section undergoes heat treatment in the heat treatment chamber 100, while the other section undergoes uniform cooling in the external gear ring 211 at the outlet of the heat treatment chamber 100, so that heat treatment and cooling are carried out simultaneously. Then, this step is repeated until the last section of the pipe undergoes heat treatment in the heat treatment chamber 100.

[0096] When the last section of the pipe is heat-treated in the heat treatment chamber 100, the first telescopic member 221 at the outlet of the heat treatment chamber 100 extends, causing the clamping plate 222 to clamp the pipe. The drive member 214 drives the transmission shaft 215 to rotate, thereby driving the gear 212 to rotate, which in turn drives the external gear ring 211 to rotate. This causes the pipe to rotate through the clamping plate 222, making the heat treatment of the pipe uniform. At the same time, the cooling member 230 is activated to cool the section of the pipe after heat treatment. During the cooling process, the position of the cooling member 230 is changed by the retraction and extension of the first telescopic member 221 at regular intervals, thereby achieving uniform cooling. After the heat treatment is completed, the first telescopic member 221 at the outlet of the heat treatment chamber 100 retracts, causing the clamping plate 222 to separate from the pipe. Under the action of the elastic member 227, the rolling member 2233 extends out of the moving groove 2231 to achieve rolling support with the pipe. Then, the second conveying mechanism 400 conveys the pipe.

[0097] When the last section of heat-treated pipe enters the external gear ring 211 at the outlet of the heat treatment chamber 100, the second conveying mechanism 400 stops conveying, the first telescopic member 221 at the outlet of the heat treatment chamber 100 extends, so that the rolling member 2233 contacts the pipe, and the clamping plate 222 does not contact the pipe. Then, the drive member 214 at the outlet of the heat treatment chamber 100 drives the transmission shaft 215 to rotate, thereby driving the gear 212 to rotate, which in turn drives the external gear ring 211 to rotate, thereby driving the cooling member 230 to rotate, so as to uniformly cool the pipe. After the cooling is completed, the second conveying mechanism 400 starts to convey the pipe.
