Abstract
Description
Technical Field
[0001] This invention relates to the field of processing technology, and specifically to a multi-roll plate rolling machine for processing tank bodies of oil tankers. Background Technology
[0002] Multi-roll plate bending machines, used for processing tanker truck bodies, are core metal sheet forming equipment. Through the coordinated movement of multiple working rollers, driven by hydraulic or mechanical force, the metal sheet required for the tanker truck body undergoes multiple continuous bending processes, resulting in permanent plastic deformation and ultimately forming a cylindrical or curved tank structure that meets the requirements. These machines typically feature adjustable functions, allowing for adaptation to different tank sizes by adjusting the roller position and spacing. Some also integrate pre-bending mechanisms to pre-process the metal sheet ends, avoiding straight edge residue and significantly improving the rolling accuracy, efficiency, and sealing performance of the tank. They are widely used in the processing of tanks for pressure vessels such as tanker trucks.
[0003] Existing multi-roll plate bending machines for processing oil tanker bodies typically operate at room temperature (which changes naturally with ambient temperature) when performing multiple continuous bending plastic deformations on metal plates. At room temperature, the plasticity of the metal plate is poor and its deformation resistance is high. During the multiple continuous bending process, the internal stress of the metal plate is difficult to be fully released, which can easily lead to defects such as cracks, creases, and edge warping. It may also cause problems such as uneven thickness of the metal plate and excessive springback. As the core pressure vessel for storing and transporting flammable and explosive hazardous materials such as fuel, the sealing performance, structural strength, and pressure resistance of oil tanker bodies are directly related to transportation safety. If the above defects exist, it may cause safety accidents such as leakage and rupture. Summary of the Invention
[0004] To address the aforementioned shortcomings of existing technologies, this invention provides a multi-roll plate bending machine for processing tanker bodies of oil tankers. This machine effectively solves the problems of poor plasticity and high deformation resistance of metal plates at room temperature, and the difficulty in fully releasing internal stress during multiple continuous bending processes, which easily leads to defects such as cracks, creases, and edge warping.

A scale detector is fixedly connected to the upper surface of the second fixing strip near the sliding hole, and the scale detector is electrically connected to the controller.
[0010] Preferably, the two integral heating components include hollow plates respectively fixedly connected to one side of the first fixing strip and the second fixing strip. Each of the two hollow plates has a plurality of spray holes arranged in a rectangular array on the side facing the first fixing strip and the second fixing strip. Each of the two hollow plates is fixedly connected to an electrically controlled air intake valve, which is electrically connected to a controller. The output end of the electrically controlled air intake valve is interconnected with the spray holes.

[0011] Preferably, the two power rods are rotatably connected between two opposite pads, the two vibration components are located between the two power rods, the temperature difference heating component is located between the two vibration components, the porous cleaning rod is rotatably connected between the two pads, and the porous cleaning rod is close to the power rod away from the multi-roll plate bending machine, and the output end of the porous cleaning rod is fixedly connected to a connecting pipe.
[0012] Preferably, the vibration assembly includes a rotating rod rotatably connected to the opposite surfaces of two pads. The other end of the rotating rod near the drive assembly is fixedly connected to the power shaft. A counterweight column is fixedly connected to the other side of the rotating rod.

[0013] The technical solution provided by this invention has the following advantages compared with the known prior art: 1. By using the fixed clamping component and the movable clamping component in the detection conveying mechanism, the thickness of metal plates of different thicknesses can be clamped and detected. The fixed clamping component, being fixed to the movable frame, acts as the "base" for the metal plate. The lifting female structure in the fixed clamping component, in conjunction with the lifting sub-structure in the movable clamping component, allows the movable clamping component to move closer to and further away from the fixed clamping component, thus clamping the metal plate. A scale in the fixed clamping component, in conjunction with a scale detector in the movable clamping component, detects the distance between the fixed and movable clamping components, thereby determining the thickness of the metal plate. This thickness provides data for subsequent heating of the cut metal plate. The precise coordination of the scale and scale detector allows for real-time acquisition of metal plate thickness data, eliminating the cumbersome and costly process of setting up separate clamping and detection equipment. Furthermore, the simultaneous clamping and detection process improves operational efficiency and ensures that heating parameters are adapted to different metal plate specifications.
[0014] 2. By using an integrated heating component in the conveying mechanism in conjunction with an air heater, the metal plate is initially heated as a whole. The air heater draws in and heats outside air, and the heated air is applied to the entire metal plate through the heating component to provide conditions for further heating. The heating component evenly distributes the hot air across the entire metal plate, which can quickly achieve initial preheating of the metal plate, making the temperature of the metal plate more uniform and avoiding excessive local temperature differences that may affect the subsequent processing effect. It also lays a stable temperature foundation for the subsequent heating stage, reducing the energy consumption and time cost of subsequent heating. It can reduce the risk of deformation of the metal plate due to local overheating, thereby ensuring the quality stability and efficiency of subsequent processing of the metal plate.
[0015] 3. The vibration preheating mechanism, consisting of a power rod, a vibration component, and a temperature difference heating component, guides the metal plate between the fixed clamping component and the moving clamping component, further heats it, and strikes it during heating. The power rod, located at the beginning and end of the fixed and moving clamping components, moves the metal plate. The temperature difference heating component, situated between the two vibration components, strikes the metal plate while heating it. This temperature difference heating component achieves the goal of heating the metal plate at a high temperature in the middle and a lower temperature at the sides. The differential heating component is specifically designed to achieve a high heating temperature in the middle of the metal plate and a low temperature on both sides. This not only meets the need for greater plastic deformation in the middle area during can rolling, but also reduces the problem of uneven deformation caused by overall overheating of the metal plate. At the same time, the differential heating component is located between two vibration components, and simultaneously taps the metal plate during the heating process. This promotes the release of internal stress in the metal plate, reduces deformation resistance, and effectively reduces defects such as cracks and springback. It also allows heat to penetrate more evenly, further improving the plasticity of the metal plate and laying the foundation for the precise bending and forming of the subsequent multi-roll plate rolling machine.

Detailed Implementation
[0019] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.
[0020] The present invention will be further described below with reference to embodiments.
[0021] Example: Refer to Figures 1 to 17 A multi-roll plate rolling machine for processing tank bodies of oil tank trucks, comprising: Multi-roll plate bending machine 1; The inspection conveying mechanism 2 includes a movable frame 21 located on the side of the multi-roll plate bending machine 1. The upper end face of the movable frame 21 is provided with a fixed clamping component 22 and a movable clamping component 26 from bottom to top. A metal plate 100 is clamped between the fixed clamping component 22 and the movable clamping component 26. The fixed clamping component 22 is provided with a driving component 23 and a linkage component 24. The fixed clamping component 22 and the movable clamping component 26 are both provided with an integral heating component 28 on one side. The vibration preheating mechanism 3 has two components, and the two vibration preheating mechanisms 3 are respectively located on the opposite sides of the fixed clamping assembly 22 and the movable clamping assembly 26. Each vibration preheating mechanism 3 includes two power rods 31, two vibration components 32, a temperature difference heating component 33, and a porous cleaning rod 34, which are arranged on the side of the linkage assembly 24 facing the overall heating assembly 28.
[0022] The movable clamping component 26, located above the fixed clamping component 22 in the detection and conveying mechanism 2, moves closer to the fixed clamping component 22 to clamp the metal plate 100 between them. As the movable clamping component 26 moves closer to or further away from the fixed clamping component 22, different spacing specifications are formed, thereby clamping metal plates 100 of different thicknesses according to the spacing. The movement of the movable clamping component 26 towards or away from the fixed clamping component 22 is powered by the drive component 23 located in the fixed clamping component 22, which in turn drives the linkage component 24 located in the movable clamping component 26 to move closer to or further away from the drive component 23. As the drive component 23 moves, it also drives the movable clamping component 26 to move synchronously, thereby achieving the clamping of metal plates 100 of different thicknesses.
[0023] Reference Figure 1 , Figures 5 to 7 A magnet 211 is fixedly connected to the bottom of the moving frame 21 facing the multi-roll plate rolling machine 1, and the magnet 211 is magnetically connected to the multi-roll plate rolling machine 1. A controller is provided on the side of the moving frame 21. The fixed clamping assembly 22 includes two first hollow fixing blocks 221 fixedly connected to both sides of the upper end face of the movable frame 21 along the length direction. Each first hollow fixing block 221 has a lifting female structure 222 on both sides along the length direction. Each lifting female structure 222 includes a first mounting block 2221 fixedly connected to the side of the first hollow fixing block 221. A motor 2222 is fixedly connected to the center of the first mounting block 2221, and the motor 2222 is electrically connected to the controller. A threaded rod 2223 is fixedly connected to the output end of the motor 2222.
[0024] By using the magnetic connection between magnet 211 and multi-roll plate bending machine 1, the movable frame 21 is fixed in multi-roll plate bending machine 1. This achieves the purpose of preheating when multi-roll plate bending machine 1 needs to bend metal plates 100 with high counterweight requirements, such as oil tanker bodies, to produce permanent plastic deformation. When multi-roll plate bending machine 1 is used to bend metal plates 100 with ordinary low requirements to produce permanent plastic deformation, the movable frame 21 can be detached from multi-roll plate bending machine 1.
[0025] Reference Figures 6 to 7 Two first hollow fixing blocks 221 are fixedly connected to one side of each block along their length direction by a first fixing strip 223, and a scale 224 is fixedly connected to the side of the first fixing strip 223 facing the movable clamping assembly 26. The drive assembly 23 includes a dual-head motor 231 fixedly connected inside one of the first hollow fixed blocks 221. Both output ends of the dual-head motor 231 are fixedly connected to shafts 232, and the shafts 232 are fixedly connected to multiple face gears 233.
[0026] The linkage component 24 includes two power shafts 243 rotatably connected to the side of the first fixed bar 223 facing the pad block 25. Two vibration shafts 242 and one cleaning shaft 241 are rotatably connected between the two power shafts 243. The ends of the power shafts 243, vibration shafts 242 and cleaning shafts 241 facing the dual-head motor 231 are all fixedly connected with bevel gears 244. The number and position of the bevel gears 244 and the face gears 233 correspond one-to-one and they mesh with each other.
[0027] The distance between the movable clamping component 26 and the first hollow fixed block 221 is measured using a scale 224. This distance is used to represent the thickness of the metal plate 100 clamped between the fixed clamping component 22 and the movable clamping component 26, so as to control the heating temperature change of the overall heating component 28 and the temperature difference heating component 33 based on the detected thickness of the current metal plate 100.
[0028] Reference Figure 4 , Figures 8 to 11The movable clamping assembly 26 includes two second hollow fixing blocks 261 slidably connected to the upper surface of the movable frame 21, and the second hollow fixing blocks 261 correspond to the first hollow fixing block 221. Each second hollow fixing block 261 has a lifting substructure 262 on both sides of its length direction. The lifting substructure 262 includes a second mounting block 2621 fixedly connected to the side of the second hollow fixing block 261. A threaded hole block 2622 is fixedly connected to the center of the second mounting block 2621, and the threaded hole block 2622 is threadedly connected to the threaded rod 2223. A second fixing strip 263 is fixedly connected to one side of each of the two second hollow fixing blocks 261 in its length direction. A sliding hole 2631 is opened on the upper surface of the second fixing strip 263 corresponding to the position of the scale 224, and the scale 224 passes through the sliding hole 2631. A scale detector 27 is fixedly connected to the upper surface of the second fixing strip 263 near the sliding hole 2631, and the scale detector 27 is electrically connected to the controller.
[0029] The lifting substructure 262 in the second hollow fixing block 261 of the movable clamping assembly 26 is used to connect with the lifting mother structure 222. The lifting mother structure 222 drives the second hollow fixing block 261 to move closer to or away from the first hollow fixing block 221 by driving the lifting substructure 262 to rise or fall. The threaded hole block 2622 in the lifting substructure 262 is threadedly connected to the threaded rod 2223. When the threaded rod 2223 rotates in both directions, the threaded hole block 2622 drives the second mounting block 2621 to move accordingly. The movement of the second mounting block 2621 will further drive the second hollow fixing block 261 to move closer to or away from the first hollow fixing block 221.
[0030] Reference Figures 8 to 9 The two integral heating components 28 include hollow plates 281 respectively fixedly connected to one side of the first fixing bar 223 and the second fixing bar 263. Each hollow plate 281 has a plurality of spray holes 284 in a rectangular array on the side facing the first fixing bar 223 and the second fixing bar 263. Each hollow plate 281 is fixedly connected to an electrically controlled air intake valve 282, which is electrically connected to a controller. The output end of the electrically controlled air intake valve 282 is connected to the spray holes 284, and the input end of the electrically controlled air intake valve 282 is fixedly connected to a delivery pipe 283. Each of the opposite sides of the two first fixing bars 223 and the second fixing bar 263 is fixedly connected to a pad 25.
[0031] The metal plate 100 sandwiched between the second hollow fixing block 261 and the first hollow fixing block 221 is heated as a whole using the nozzle 284 in the overall heating assembly 28 (the heating temperature at this time is low temperature heating).
[0032] Reference Figures 12 to 15Two power rods 31 are rotatably connected between two opposite pads 25. Two vibration components 32 are located between the two power rods 31. A temperature difference heating component 33 is located between the two vibration components 32. A porous cleaning rod 34 is rotatably connected between the two pads 25. The porous cleaning rod 34 is close to the power rod 31 that is away from the multi-roll plate rolling machine 1. The output end of the porous cleaning rod 34 is fixedly connected to a connecting pipe 341.
[0033] The power shaft 243 located in the first hollow fixed block 221 drives the corresponding power rod 31 to rotate, while the cleaning shaft 241 of the first hollow fixed block 221 drives the corresponding porous cleaning rod 34 to rotate, and the vibration shaft 242 of the first hollow fixed block 221 drives the corresponding vibration component 32 to rotate.
[0034] Reference Figures 13 to 16 The vibration component 32 includes a rotating rod 321 rotatably connected to the opposite faces of two pads 25. The other end of the rotating rod 321 near the drive component 23 is fixedly connected to the power shaft 243. A counterweight column 322 is fixedly connected to the other side of the rotating rod 321. Multiple resonance structures 324 and buffer structures 323 are alternately arranged between the two counterweight columns 322. The resonance structure 324 includes a hollow outer column 3241 fixedly connected to the other side of the counterweight column 322. Multiple resonance plates 3242 are fixedly connected to the inner circumferential surface of the hollow outer column 3241 in a ring array. The other end of each resonance plate 3242 is fixedly connected to a hollow inner column 3243. Multiple first collision protrusions 3244 are fixedly connected to the inner circumferential surface of the hollow inner column 3243 in a ring array. Multiple collision balls 325 are placed inside the hollow inner column 3243. The buffer structure 323 includes two fixed covers 3231 fixedly connected to the opposite faces of two hollow outer columns 3241. Multiple elastic tubes 3232 are fixedly connected in a ring array on the inner circumferential surface of the two fixed covers 3231, and each elastic tube 3232 is filled with gas. The other end of each elastic tube 3232 is fixedly connected to a central disk 3233, and a connecting rod 3234 is fixedly connected to the opposite face of the central disk 3233.
[0035] The rotating rod 321 in the vibration assembly 32 is used to achieve a rotational connection with the pad block 25. The rotating rod 321 in the vibration assembly 32 located in the first hollow fixed block 221 is fixedly connected to the corresponding vibration shaft 242, so that the power rod 31 located in the first hollow fixed block 221 drives the corresponding rotating rod 321 to rotate. The rotation of the rotating rod 321 will further drive the counterweight column 322, multiple resonance structures 324 and buffer structures 323 to rotate. Since the rotation of multiple resonance structures 324 and buffer structures 323 is located between the counterweight column 322, the counterweight column 322 stabilizes the vibration frequency when the multiple resonance structures 324 and buffer structures 323 are clamped with the metal plate 100.
[0036] Reference Figure 12 , Figure 17 The temperature difference heating component 33 includes a heat insulation box 331 fixedly connected between two adjacent pads 25. Two ceramic blocks 332 and a mesh roller 333 are fixedly connected along the length of the heat insulation box 331. Heating rods are provided inside both the ceramic blocks 332 and the mesh roller 333. The heating rod inside the mesh roller 333 has a higher power than the heating rod inside the ceramic blocks 332, and the heating rod is electrically connected to the controller.
[0037] The ceramic block 332 and the mesh roller 333 in the temperature difference heating component 33 are used to heat the metal plate 100 passing through it. The mesh roller 333 heats the middle position of the metal plate 100, while the ceramic block 332 heats the two sides of the metal plate 100, so that the temperature entering the center of the metal plate 100 is greater than the temperature of the two sides.
[0038] Reference Figures 1 to 2 It also includes a conveying mechanism 4, which includes a vacuum cleaner 41 and an air heater 43 fixedly connected to the bottom of the movable frame 21. Both the vacuum cleaner 41 and the air heater 43 are electrically connected to the controller. A three-way valve 42 is fixedly connected to the side of the movable frame 21 facing the conveying pipe 283. The output end of the vacuum cleaner 41 is fixedly connected to the output pipe 411. The other end of the output pipe 411 is connected to the input end of the three-way valve 42. Both output ends of the three-way valve 42 are fixedly connected to the branch pipe 421. The other end of the branch pipe 421 is fixedly connected to the connecting pipe 341. The output end of the air heater 43 is fixedly connected to a diversion valve, and the other end of the delivery pipe 283 is connected to the two output ends of the diversion valve.
[0039] The suction power generated by the vacuum cleaner 41 is transmitted to the three-way valve 42 through the output pipe 411 of the vacuum cleaner 41, and then transmitted to the connecting pipe 341 through the diversion of the three-way valve 42. In turn, the connecting pipe 341 transmits the suction power to the porous cleaning rod 34 located in the first hollow fixing block 221 and the second hollow fixing block 261 respectively.
[0040] The specific operating principle of this embodiment is as follows: Step 1: First, the operator pushes the movable frame 21 to the side of the multi-roll plate bending machine 1, so that the magnet 211 at the bottom of the movable frame 21 is attached to the outer wall of the multi-roll plate bending machine 1 to fix the detection conveying mechanism 2 and ensure that the subsequent metal plate 100 conveying path is aligned with the feed port of the multi-roll plate bending machine 1.
[0041] Then, the operator starts the motors 2222 (a total of 4, located on both sides of the length of the two first hollow fixed blocks 221) of the lifting female structure 222 in the fixed clamping assembly 22 through the controller, so that the motors 2222 drive the threaded rods 2223 to rotate clockwise. Since the threaded rods 2223 are threadedly engaged with the threaded hole block 2622 of the lifting substructure 262 in the moving clamping assembly 26, the second hollow fixed block 261 is driven to move away from the first hollow fixed block 221 along the slide rail on the upper end face of the moving frame 21 until the distance between the fixed clamping assembly 22 and the moving clamping assembly 26 reaches the maximum value. At this time, the operator places the metal plate 100 to be processed on the upper surface of the first fixing bar 223 of the fixing clamping assembly 22, and the processing start end of the metal plate 100 (the end that needs to enter the multi-roll plate rolling machine 1 first) faces the multi-roll plate rolling machine 1. At this time, the lower surface of the metal plate 100 contacts the outer surface of the power rod 31, vibration assembly 32, temperature difference heating assembly 33 and porous cleaning rod 34 on the first fixing bar 223 to ensure uniform force during subsequent conveying. Then, the controller controls the motor 2222 to drive the threaded rod 2223 to rotate counterclockwise, so that the second hollow fixing block 261 moves closer to the first hollow fixing block 221 until the power rod 31, vibration assembly 32, temperature difference heating assembly 33 and porous cleaning rod 34 on the lower surface of the second fixing bar 263 are in contact with the upper surface of the metal plate 100. Then the motor 2222 stops rotating, thereby completing the clamping of the metal plate 100. At this time, the scale 224 on the side of the first fixing strip 223 passes through the sliding hole 2631 of the second fixing strip 263. The scale detector 27 (such as a laser displacement sensor) on the second fixing strip 263 automatically reads the real-time spacing data on the scale 224. This data is the actual thickness of the metal plate 100 (such as a detection value of 9.8mm). The data is transmitted to the controller in real time and stored as the basis for subsequent heating power adjustment.
[0042] Special Note: The reason why motor 2222 stops rotating in reverse is: The controller confirms that the clamping force of the metal plate 100 has reached a preset threshold (e.g., 500N) through the current feedback of the motor 2222. The motor 2222 then stops working to avoid the metal plate 100 slipping due to insufficient clamping force or the metal plate 100 being damaged due to excessive clamping force.
[0043] Step 2: After the metal plate 100 is clamped, the controller activates the air heater 43 to draw in outside air and complete the filtration and heating (the heating temperature is preset according to the material of the plate, such as 180℃ for carbon steel and 200℃ for stainless steel). The heated air is split into two paths by the diversion valve at the output end of the air heater 43, and is respectively delivered to two delivery pipes 283 that are fixedly connected to the input end of the electrically controlled air intake valve 282 of the overall heating assembly 28. The controller adjusts the opening of the electrically controlled air intake valve 282 (increases the opening for thick plates and decreases the opening for thin plates) according to the actual thickness data of the metal plate 100 detected by the scale detector 27 in the early stage, controls the flow rate of hot air delivery, and ensures heating uniformity. The hot air enters through the electrically controlled air intake valve 282 and is respectively fixed to the first fixed strip 22. 3. Inside the hollow plate 281 on one side of the second fixed bar 263, after being fully diffused and evenly distributed within the hollow plate 281, the air is sprayed synchronously and comprehensively onto the upper and lower surfaces of the metal plate 100 through multiple spray holes 284 opened in a rectangular array facing the metal plate 100. During the entire process of pre-treatment of the metal plate 100 in the sequence of "power rod 31 → porous cleaning rod 34 → vibration assembly 32 → temperature difference heating assembly 33 → another vibration assembly 32 → another power rod 31", the overall heating assembly 28 continuously sprays hot air to keep the overall temperature of the metal plate 100 stable at the preset preheating temperature, initially improving the plasticity of the plate and laying a uniform temperature foundation for the subsequent temperature difference heating and stress release stages, until the metal plate 100 is about to enter the multi-roll plate rolling machine 1 and then shut off.
[0044] Special Note: The air heater 43 mainly consists of a housing, an air filter module, a heating element, an airflow channel, and a temperature control and connection interface. The filter module has a built-in metal filter or non-woven filter material that can intercept dust, impurities, and other particulate matter in the outside air. The heating element uses an electric heating wire or a PTC ceramic heating element and is electrically connected to the controller. It can receive controller commands to adjust the heating power according to the material and thickness of the plate. The airflow channel ensures smooth airflow. Together with the air intake structure at the input end and the diverter valve connection interface at the output end, the outside air is drawn in, first passes through the filter module to remove impurities, and then flows through the heating element to be heated to the preset temperature, ultimately realizing the function of filtering and heating the drawn outside air.
[0045] At the same time, the controller activates the drive assembly 23 inside the fixed clamping assembly 22, namely the dual-head motor 231 inside the first hollow fixed block 221, so that the two output ends of the dual-head motor 231 drive the shaft 232 to rotate synchronously. Because the multiple face gears 233 on the shaft 232 (corresponding to the power shaft 243, vibration shaft 242, and cleaning shaft 241) mesh with the bevel gears 244 at one end of each shaft in the linkage assembly 24, the power is transmitted to the power shaft 243, vibration shaft 242, and cleaning shaft 241, so that they rotate synchronously.
[0046] Step 3: When the power shaft 243 on the side of the first hollow fixed block 221 drives the corresponding power rod 31 to rotate, the outer surface of the power rod 31 comes into frictional contact with the lower surface of the metal plate 100, thereby driving the metal plate 100 to move towards the multi-roll plate rolling machine 1. At this time, the power rod 31 corresponding to the power rod 31 of the second hollow fixed block 261 and the first hollow fixed block 221 is forced to rotate due to the friction generated by the movement of the metal plate 100, which helps the metal plate 100 to maintain stable conveying.
[0047] As the metal plate 100 moves toward the multi-roll plate rolling machine 1, it moves to the position of the porous cleaning rod 34. At the same time, the cleaning shaft 241 of the first hollow fixing block 221 drives the porous cleaning rod 34 to rotate, and the vacuum cleaner 41 is also started simultaneously. This causes the negative pressure generated by the vacuum cleaner 41 to be transmitted to the interior of the porous cleaning rod 34 through the output pipe 411, the three-way valve 42, the branch pipe 421 and the connecting pipe 341. The porous cleaning rod 34 sucks the dust, iron filings and other impurities on the surface of the metal plate 100 into the vacuum cleaner 41 through multiple holes, thus completing the cleaning of the surface of the metal plate 100. During this process, the porous cleaning rod 34 of the second hollow fixing block 261 is forced to rotate due to the movement of the metal plate 100, thus completing the cleaning of the upper surface.
[0048] After the metal plate 100 is cleaned, it enters the first vibration component 32 (the vibration component 32 near the porous cleaning rod 34). As the vibration shaft 242 of the first hollow fixed block 221 drives the rotating rod 321 of the vibration component 32 to rotate, the rotating rod 321 drives the counterweight column 322 to rotate synchronously, thereby driving the resonance structure 324 and the buffer structure 323 set between the counterweight columns 322 to rotate.
[0049] When the resonant structure 324 rotates, the hollow outer column 3241 drives the hollow inner column 3243 to rotate through the resonant plate 3242. The collision ball 325 inside the hollow inner column 3243 continuously collides with the first collision protrusion 3244 on the inner circumferential surface, generating high-frequency vibration. The vibration is transmitted to the lower surface of the metal plate 100 through the hollow outer column 3241. The elastic tube 3232 (filled with compressed air) in the buffer structure 323 buffers the vibration impact through elastic deformation, preventing the resonant structure 324 from damaging the metal plate 100 due to excessive vibration. Since the vibration component 32 on the side of the first hollow fixed block 221 is actively driven by the vibration shaft 242, the power is greater than that of the passively rotating vibration component 32 on the side of the second hollow fixed block 261. The vibration frequencies on the upper and lower surfaces of the metal plate 100 are inconsistent (50Hz on the lower surface and 30Hz on the upper surface), which initially releases the initial stress inside the metal plate 100.
[0050] When the metal plate 100 passes through the first vibration component 32, it enters the area of the temperature difference heating component 33. The controller adjusts the power of the heating rod in the temperature difference heating component 33 based on the previously detected thickness data of the metal plate 100. Because two ceramic blocks 332 (with internal heating rod power set to 2kW) are located on both sides of the metal plate 100 in the heat insulation box 331 of the temperature difference heating component 33, and a mesh roller 333 (with internal heating rod power set to 4kW) is located in the middle of the metal plate 100, the temperature difference heating effect of the metal plate 100 with a high heating temperature in the middle (e.g., 250℃) and a low heating temperature on both sides (e.g., 180℃) is achieved. This is suitable for the requirement of greater plastic deformation in the middle area when rolling the tank body of the oil tanker. At the same time, the vibration components 32 on both sides (the first vibration component 32 and the subsequent second vibration component 32) continuously vibrate and strike the heated metal plate 100, releasing the thermal stress generated during the heating process of the metal plate 100 through vibration, and preventing the metal plate 100 from cracking due to thermal stress concentration.
[0051] After passing through the temperature difference heating component 33, the metal plate 100 enters the second vibration component 32 (near the side of the multi-roll plate bending machine 1). The working principle of the vibration component 32 is the same as that of the first vibration component 32. It is actively driven by the vibration shaft 242 on the side of the first hollow fixed block 221 to generate high-frequency vibration, which releases the deep stress on the heated metal plate 100 and further improves the plasticity of the metal plate 100, preparing for the bending and forming of the subsequent multi-roll plate bending machine 1. During this process, the second vibration component 32 on the side of the second hollow fixed block 261 still moves and rotates passively with the metal plate 100 to complete the stress release on the upper surface. After the metal plate 100 completes stress release, it enters the position of the second power rod 31 on the side close to the multi-roll plate rolling machine 1. The power rod 31 on the side of the first hollow fixed block 221 rotates actively, and the power rod 31 on the side of the second hollow fixed block 261 rotates passively. Together, they smoothly transport the pre-treated metal plate 100 to the feed port of the multi-roll plate rolling machine 1. The multi-roll plate rolling machine 1 performs multiple continuous bending on the metal plate 100, and finally rolls it into the cylindrical or arc-shaped structure required for the tanker tank body.
[0052] When the metal plate 100 is completely conveyed to the multi-roll plate rolling machine 1, the controller sequentially shuts down the dual-head motor 231, motor 2222, vacuum cleaner 41 and air heater 43. Motor 2222 drives the threaded rod 2223 to rotate clockwise, causing the second hollow fixing block 261 to move away from the first hollow fixing block 221 and return to the initial spacing, waiting for the next batch of metal plates 100 to be processed. If no further processing is required, the moving frame 21 can be separated from the multi-roll plate rolling machine 1 to complete the equipment reset.
