Description

Technical Field

[0001] This application relates to the field of shipbuilding technology, and more specifically, to a plate processing control system and a plate processing method. Background Technology

[0002] In shipbuilding, after sections undergo hot processing such as bulkhead welding, section assembly, and excess material cutting, the bulkheads and other structural components will exhibit varying degrees of hot processing deformation (including large-area wrinkles, dents, bulges, etc.). These deformations need to be corrected later through operations such as heat straightening and mechanical cold bending. However, these corrective operations can easily lead to damage and deformation of the paint coating and surrounding iron outfitting components, and may even affect the positioning of the precision base.

[0003] In the current environment of significantly improved production efficiency and precision, the need to reduce the negative impact of hot working on ships or marine engineering is becoming increasingly urgent. While deformation can be reduced through extended stress release and overall preheating of the base material during the cutting and assembly stage, this is not feasible during the section assembly and slipway stage due to the size of the sections and the construction schedule. Summary of the Invention

[0004] The purpose of this application is to provide a plate processing control system and a plate processing method. The plate processing control system of this application uses a track-type flow loop to transport a pre-temperature medium to regulate the plate temperature, reduce temperature difference and temperature gradient, reduce thermal stress and deformation, and improve the quality of shipbuilding.

[0005] In the first aspect, a sheet metal processing control system is provided for welding or cutting sheet metal. The weld seam or cutting line is collectively referred to as the construction line, and the sheet metal on both sides of the construction line is referred to as the first sheet metal surface and the second sheet metal surface.

[0006] The sheet metal processing control system includes a first track, a second track, a medium source device, and a processing device. The first track is attached to the surface of the first sheet metal and extends along the construction line, with a first flow loop within it. The second track is attached to the surface of the second sheet metal and extends along the construction line, with a second flow loop within it. The medium source device is connected to both the first and second flow loops, and is used to supply a medium at a predetermined temperature to both loops. The processing device is equipped with a device for welding or cutting along the construction line. The processing device includes a first and second traveling wheels, with the first traveling wheel moving along the first track and the second traveling wheel moving along the second track.

[0007] In one feasible embodiment, the sheet metal processing control system further includes: several temperature sensors disposed on the first and second sheet metal surfaces on both sides of the construction line; and a control module electrically connected to the temperature sensors and the medium source device; wherein the control module adjusts the temperature of the medium supplied by the medium source device to the first and second flow loops based on the temperature signals received from the temperature sensors.

[0008] In one feasible scheme, several temperature sensors are divided into two groups; the first group of temperature sensors is set on the surface of the first plate on both sides of the first track; the second group of temperature sensors is set on the surface of the second plate on both sides of the second track.

[0009] In one feasible embodiment, the first track includes a going pipeline and a returning pipeline, which are close to each other to form the first track; the proximal end of the going pipeline is connected to the medium outlet of the medium source device, the proximal end of the returning pipeline is connected to the medium return port of the medium source device, and the distal ends of the going pipeline and the returning pipeline are connected to form a first flow loop; the second track has the same structure as the first track.

[0010] In one feasible solution, both the outgoing and returning pipelines are provided with opposing semi-groove structures, and the outgoing and returning pipelines form an upward-opening groove structure when they are close together; the first and second traveling wheels of the processing device travel along the groove structure.

[0011] In one feasible solution, the bottom width of both the outgoing and returning conduits is greater than the top width.

[0012] In one feasible solution, a thermal insulation layer is installed between the outgoing and returning conduits.

[0013] In one feasible solution, a heat-conducting layer is provided on the bottom surface of both the outgoing and returning pipes.

[0014] Secondly, a plate processing method is also provided, which uses the aforementioned plate processing control system to perform welding operations on the plate; the plate processing method includes:

[0015] S11. The control module controls the operation of the medium source device to deliver a medium at a predetermined temperature into the first flow circuit and the second flow circuit, so as to raise the temperature of the plates on both sides of the weld seam.

[0016] S12. When the real-time temperature values ​​of the first plate surface and the second plate surface reach the first threshold by the temperature signal from the temperature sensor, the control module controls the processing device to move along the first track and the second track and weld the weld seam.

[0017] S13. During the welding process, when the control module determines that the real-time temperature value is greater than the second threshold based on the temperature signal from the temperature sensor, it controls the medium source device to output a medium with a temperature lower than the second threshold. This medium absorbs the temperature of the plate through the first flow loop and the second flow loop to reduce the plate temperature. The second threshold is greater than the first threshold.

[0018] S14. The control module determines, through the temperature signal from the temperature sensor, that when the real-time temperature values ​​of the first and second plate surfaces drop to the first threshold, the medium source device is stopped.

[0019] S15. The control module monitors the temperature of the temperature sensor in real time and repeats steps S13 to S15 until the welding is completed.

[0020] S16. After welding is completed, the control module controls the medium source device to work and deliver the medium to the first flow circuit and the second flow circuit. The temperature of the medium decreases by the first temperature gradient value after a unit time interval, so that the temperature of the plates on both sides of the weld gradually decreases to room temperature in the form of a gradient decrease.

[0021] Thirdly, a method for processing sheet metal is also provided, which uses the aforementioned sheet metal processing control system to perform cutting operations on the sheet metal; the sheet metal processing method includes:

[0022] S21. The control module controls the processing device to move along the first track and the second track so that the processing device cuts the plate along the cutting line;

[0023] S22. During the cutting process, the control module determines that the real-time temperature values ​​of the first and second plate surfaces are greater than the third threshold by using the temperature signal from the temperature sensor. When this is true, the control medium source device outputs a medium with a temperature lower than the third threshold, which absorbs the plate temperature through the first and second flow loops to reduce the plate temperature.

[0024] S23. When the control module determines that the real-time temperature values ​​of the first and second plate surfaces have dropped below the third threshold based on the temperature signal from the temperature sensor, it stops the medium source device.

[0025] S24. The control module continues to monitor the temperature of the temperature sensor and repeats steps S22 to S24 until the cutting is completed.

[0026] S25. After the cutting is completed, the control module controls the medium source device to work and deliver the medium to the first flow circuit and the second flow circuit. The temperature of the medium decreases by the second temperature gradient value after a unit time interval, so that the temperature of the plates on both sides of the cutting seam gradually decreases to room temperature in the form of a gradient decrease.

[0027] Compared with existing technologies, the beneficial effects of this application include at least the following: In the plate processing control system of this application, a first track is attached to the first plate surface on one side of the construction line, and a second track is attached to the second plate surface on the other side, with both tracks extending along the construction line. This ensures that the temperature control range is fully matched with the core area of ​​hot processing (the construction line and the plates on both sides), reducing temperature control blind spots. The medium source device delivers a medium at a predetermined temperature into the flow loop within the two tracks. Through medium circulation, it directly acts on the plates on both sides of the construction line to regulate the plate temperature on both sides of the construction line, reduce the temperature difference between the processing area and the surrounding area, control the temperature change gradient, reduce the accumulation of thermal stress, reduce and control the deformation caused by hot processing, and improve the quality of shipbuilding.

[0028] Furthermore, several temperature sensors are installed on the sheet metal surfaces on both sides of the construction line to directly collect real-time temperatures in the core heat processing areas, providing a precise data source to cover easily deformable critical areas and eliminating temperature monitoring blind spots. After receiving the sensor signals, the control module analyzes and judges the temperature. When the sheet metal temperature deviates from the preset range, it adjusts the temperature of the medium output from the medium source device to the two flow loops, achieving dynamic temperature balance on both sides of the construction line and reducing heat processing deformation caused by temperature differences from the source. The system eliminates the need for frequent manual temperature control; the control module automatically completes monitoring, judgment, and adjustment, reducing human error. A stable temperature environment, combined with the processing device moving along the track, also improves the straightness of weld seams and the flatness of cut surfaces, ensuring processing accuracy and reducing rework later. Simultaneously, the system can flexibly adjust medium parameters based on sensor signal differences to adapt to welding and cutting scenarios, eliminating the need for separate equipment configuration and improving versatility and practicality.

Detailed Implementation

[0033] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. The components of the embodiments of this application described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0034] Therefore, the following detailed description of the embodiments of this application provided in the accompanying drawings is not intended to limit the scope of the claimed application, but merely to illustrate selected embodiments of the application. All other embodiments obtained by those skilled in the art based on the embodiments of this application without inventive effort are within the scope of protection of this application.

[0035] like Figure 1 As shown, this application embodiment first provides a sheet metal processing control system for welding or cutting sheet metal. The welding seam or cutting line is collectively referred to as the construction line 03, and the sheet metal on both sides of the construction line 03 is referred to as the first sheet metal surface 01 and the second sheet metal surface 02.

[0036] The sheet metal processing control system includes a first track 1, a second track 2, a medium source device 3, and a processing device 4. The first track 1 is attached to the surface 01 of the first sheet metal and extends along the construction line 03, and a first flow loop is provided within the first track 1. The second track 2 is attached to the surface 02 of the second sheet metal and extends along the construction line 03, and a second flow loop is provided within the second track 2.

[0037] The medium source device 3 is connected to the first flow circuit and the second flow circuit respectively, and the medium source device 3 is used to supply a medium at a predetermined temperature to the first flow circuit and the second flow circuit. The processing device 4 is equipped with a device for welding or cutting the construction line 03. The processing device 4 includes a first traveling wheel 41 and a second traveling wheel 42 opposite to each other. The first traveling wheel 41 travels along the first track 1, and the second traveling wheel 42 travels along the second track 2.

[0038] In the plate processing control system of this application, the first track 1 is attached to the first plate surface 01 on one side of the construction line 03, and the second track 2 is attached to the second plate surface 02 on the other side. Both tracks extend along the construction line 03 to ensure that the temperature control range is fully matched with the core area of ​​hot processing (construction line and plates on both sides), reducing temperature control blind spots. The medium source device 3 delivers a medium at a predetermined temperature into the flow loop within the two tracks. Through medium circulation, it directly acts on the plates on both sides of the construction line to regulate the plate temperature on both sides of the construction line 03, reduce the temperature difference between the processing area and the surrounding area, control the temperature change gradient, reduce the accumulation of thermal stress, reduce and control the deformation caused by hot processing, and improve the quality of ship construction.

[0039] For example, during welding, a preheating medium can be supplied to simultaneously raise the temperature of the plates on both sides of the weld seam, reducing the temperature difference between the high-temperature welding zone and the surrounding low-temperature zone, and minimizing the accumulation of thermal stress. Similarly, during cutting, a cooling medium can be supplied to absorb the localized high temperatures generated during cutting, preventing warping of the plates caused by overheating on one side. Thus, by balancing the temperature on both sides of the construction line, heat processing deformation (such as wrinkles, dents, and bulges) is reduced from the source, eliminating the need for subsequent heat straightening or mechanical cold bending. This naturally avoids damage to paint coatings, surrounding iron outfitting components, and the impact on the positioning of the precision base during straightening operations.

[0040] In some embodiments, the medium source device 3 may include a medium circulation system for supplying a medium at a predetermined temperature to a first circulation loop and a second circulation loop and circulating the medium.

[0041] For example, a media circulation system may include a media liquid storage tank, a compressor, cooling coils, and a fan. The media liquid stored in the storage tank serves as a carrier for energy absorption and release, releasing heat in areas requiring heating and absorbing heat in areas requiring cooling. Its state is changed by the compressor, providing the core medium for energy transfer and conversion within the system. The compressor compresses the media liquid into a high-temperature, high-pressure gas through mechanical compression, thereby changing the energy state of the media liquid and providing the necessary power and conditions for subsequent energy release and heat exchange. The cooling coils serve as the operating channel for the media liquid; as the media liquid flows within the cooling coils, it completes the heat exchange process, directly adjusting the temperature by absorbing or releasing heat. The fan assists in heat exchange through airflow: on the one hand, it blows away the heat absorbed by the media liquid; on the other hand, it promotes heat exchange between the low-energy-state media liquid and the surrounding air, allowing the media liquid to absorb or release energy to raise or lower its temperature, ultimately ensuring that the media liquid smoothly enters the next heating or cooling cycle after completing energy conversion.

[0042] In some embodiments, the medium source device 3 may include two medium circulation systems, which separately control the medium circulation in the first circulation loop and the second circulation loop, thereby allowing the medium temperature in the first circulation loop and the second circulation loop to be adjusted separately.

[0043] In some embodiments, such as Figure 1 As shown, the sheet metal processing control system may further include several temperature sensors 5 and a control module 6. The temperature sensors 5 are disposed on the first sheet metal surface 01 and the second sheet metal surface 02 on both sides of the construction line 03. The control module 6 is electrically connected to the temperature sensors 5 and the medium source device 3. The control module 6 adjusts the temperature of the medium supplied by the medium source device 3 to the first and second flow loops based on the temperature signals received from the temperature sensors 5.

[0044] In this embodiment, several temperature sensors 5 installed on the first plate surface 01 and the second plate surface 02 on both sides of the construction line 03 can directly collect the real-time temperature of the core area of ​​heat processing (welding / cutting) (i.e. the plate material around the construction line 03), providing an accurate and real data source for subsequent temperature control, ensuring that the temperature control range covers the key areas that are prone to thermal deformation, and eliminating temperature monitoring blind spots.

[0045] The control module 6, electrically connected to the temperature sensor 5, can receive and analyze temperature signals in real time. When the temperature of the first plate surface 01 or the second plate surface 02 deviates from the preset range, the control module 6 directly sends a control command to the medium source device 3 to adjust the temperature of the medium supplied by the medium source device 3 to the first and second flow loops. For example, if the temperature of a plate on one side is too low during welding, the temperature of the medium in the corresponding loop can be increased to supplement heat; if the temperature of a plate on one side is too high during cutting, the temperature of the medium in the corresponding loop can be decreased to absorb heat. Ultimately, this achieves dynamic temperature balance of the plates on both sides of the construction line 03, reducing heat processing deformation caused by temperature differences from the source.

[0046] Furthermore, without the need for frequent manual temperature checks and adjustments, the control module 6 can automatically complete the entire monitoring, judgment, and control process based on the signal from the temperature sensor 5, reducing human error. Simultaneously, the temperature of the medium supplied by the medium source device 3 to the first and second flow loops, after regulation, can continuously provide a stable temperature environment for the plates on both sides of the construction line 03. Combined with the stability of the processing device 4 traveling along the track, this further improves the straightness of the weld seam and the flatness of the cut surface, ensuring the processing accuracy of the plates and indirectly reducing rework caused by accuracy deviations in later stages.

[0047] Whether it is welding operations that require maintaining the preheating temperature of the plates on both sides of construction line 03, or cutting operations that require controlling the cooling rate of the plates on both sides of construction line 03, the control module 6 can flexibly adjust the output parameters (medium temperature, delivery rate) of the medium source device 3 through the signal difference of the temperature sensor 5. This allows the same system to meet the temperature control requirements of both welding and cutting heat processing scenarios, eliminating the need to configure separate temperature control equipment for different processes and improving the system's versatility and practicality.

[0048] In some embodiments, such as Figure 1 As shown, several temperature sensors 5 are divided into two groups; the first group of temperature sensors 5 is set on the first plate surface 01 on both sides of the first track 1; the second group of temperature sensors 5 is set on the second plate surface 02 on both sides of the second track 2.

[0049] The arrangement of several temperature sensors 5 in two groups allows for precise temperature monitoring covering the first plate surface 01 and the second plate surface 02 on both sides of the first track 1 and the second track 2. This eliminates blind spots in temperature monitoring of key temperature control areas around the tracks, enabling more detailed capture of real-time temperature changes of the plates at different locations along the tracks. It accurately reflects the temperature control effect of the first and second flow loops on the surrounding plates, preventing the overheating or underheating of localized areas from being overlooked. Based on this, the control module 6 can more precisely adjust the medium parameters supplied by the medium source device to the two flow loops according to the accurate temperature signals fed back by the two sets of sensors. This further ensures the uniformity of plate temperature on both sides of the construction line 03, reducing heat processing deformation caused by localized temperature differences from the source. Simultaneously, it provides a more reliable temperature environment for the processing device to move stably along the tracks, improving the processing accuracy of welding or cutting, and enhancing the temperature control reliability and applicability of the plate processing control system in hot processing scenarios.

[0050] In some embodiments, such as Figure 2 As shown, the first track 1 may include a going pipe 101 and a returning pipe 102, which are close to each other to form the first track 1. The proximal end of the going pipe 101 is connected to the medium outlet of the medium source device 3, and the proximal end of the returning pipe 102 is connected to the medium return port of the medium source device 3. The distal ends of the going pipe 101 and the returning pipe 102 are connected to form a first flow loop.

[0051] The second track 2 has the same structure as the first track 1. The second track 2 may also include a destination pipe 101 and a return pipe 102, which are close to each other to form the second track 2. The proximal end of the destination pipe 101 is connected to another medium outlet of the medium source device 3, and the proximal end of the return pipe 102 is connected to another medium return port of the medium source device 3. The distal ends of the destination pipe 101 and the return pipe 102 are connected to form a second flow loop.

[0052] In some embodiments, such as Figure 2 As shown, both the outgoing pipe 101 and the returning pipe 102 can be provided with opposing semi-groove structures, forming an upward-opening groove structure 103 when the outgoing pipe 101 and the returning pipe 102 are close together. The first traveling wheel 41 and the second traveling wheel 42 of the processing device 4 travel along the groove structure 103.

[0053] In some embodiments, such as Figure 2 As shown, the bottom width of the outgoing pipe 101 and the return pipe 102 is greater than the top width, increasing the heat exchange area between the bottom surface of the track and the plate.

[0054] In some embodiments, such as Figure 2 As shown, a heat insulation layer 104 is provided between the outgoing pipe 101 and the returning pipe 102. Since the temperatures of the media in the outgoing pipe 101 and the returning pipe 102 will differ during the heat exchange process with the plate surface, the heat insulation layer 104 separates the outgoing pipe 101 and the returning pipe 102, reducing the waste caused by heat exchange between them.

[0055] In some embodiments, such as Figure 2 As shown, a heat-conducting layer 105 is provided on the bottom surface of both the outgoing pipe 101 and the returning pipe 102.

[0056] The thermally conductive layer 105 can be made of thermally conductive silicone. Thermally conductive silicone consists of a low thermal conductivity silicone rubber matrix and high thermal conductivity fillers (such as alumina, boron nitride, silicon carbide, silver powder, etc.). The high thermal conductivity fillers form a continuous thermally conductive network within the material, efficiently transferring heat through direct contact between filler particles and molecular vibrations (phonon conduction). Furthermore, free electrons in some fillers (such as silver powder) can further improve thermal conductivity through electron migration. The flexibility and plasticity of the silicone rubber matrix allow it to fill the tiny gaps and uneven surfaces between the welding track and the base material, reducing the presence of air layers and significantly lowering thermal resistance. In addition, those skilled in the art can further improve thermal conductivity by optimizing the type, content, particle size, and distribution of the fillers, as well as improving the interfacial bonding between the fillers and the matrix.

[0057] This application also provides a plate processing method, which uses the aforementioned plate processing control system to perform welding operations on the plate; the plate processing method includes:

[0058] S11. The control module 6 controls the operation of the medium source device 3 to deliver a medium at a predetermined temperature into the first flow circuit and the second flow circuit, so as to raise the temperature of the plates on both sides of the weld seam.

[0059] S12. When the temperature signal from the temperature sensor 5 determines that the real-time temperature values ​​of the first plate surface 01 and the second plate surface 02 have reached the first threshold, the control module 6 controls the processing device 4 to move along the first track 1 and the second track 2 and weld the weld seam.

[0060] S13. During the welding process, when the control module 6 determines that the real-time temperature value is greater than the second threshold by the temperature signal of the temperature sensor 5, the control medium source device 3 outputs a medium with a temperature lower than the second threshold, which absorbs the temperature of the plate through the first flow loop and the second flow loop to reduce the temperature of the plate; the second threshold is greater than the first threshold.

[0061] S14. The control module 6 determines, through the temperature signal from the temperature sensor 5, that when the real-time temperature values ​​of the first plate surface 01 and the second plate surface 02 drop to the first threshold, it stops the medium source device 3.

[0062] S15. The control module 6 monitors the temperature of the temperature sensor 5 in real time and repeats steps S13 to S15 until the welding is completed.

[0063] S16. After welding is completed, the control module 6 controls the medium source device 3 to work and deliver the medium to the first flow circuit and the second flow circuit. The temperature of the medium decreases by the first temperature gradient value after a unit time interval, so that the temperature of the plates on both sides of the weld gradually decreases to room temperature in the form of a gradient decrease.

[0064] This application also provides a method for processing sheet metal, which uses the aforementioned sheet metal processing control system to perform cutting operations on the sheet metal; the sheet metal processing method includes:

[0065] S21. The control module 6 controls the processing device 4 to move along the first track 1 and the second track 2, so that the processing device 4 cuts the plate along the cutting line;

[0066] S22. During the cutting process, the control module 6 determines, through the temperature signal of the temperature sensor 5, that the real-time temperature values ​​of the first plate surface 01 and the second plate surface 02 are greater than the third threshold. Then, the control medium source device 3 outputs a medium with a temperature lower than the third threshold, which absorbs the plate temperature through the first flow circuit and the second flow circuit to reduce the plate temperature.

[0067] S23. The control module 6 determines, through the temperature signal from the temperature sensor 5, that when the real-time temperature values ​​of the first plate surface 01 and the second plate surface 02 drop below the third threshold, it stops the medium source device 3.

[0068] S24. The control module 6 continues to monitor the temperature of the temperature sensor 5 and repeats steps S22 to S24 until the cutting is completed.

[0069] S25. After the cutting is completed, the control module 6 controls the medium source device 3 to work and deliver the medium to the first flow circuit and the second flow circuit. The temperature of the medium decreases by the second temperature gradient value after a unit time interval, so that the temperature of the plates on both sides of the cutting seam gradually decreases to room temperature in the form of a gradient decrease.

[0070] It should be noted that the first threshold, second threshold, third threshold, first temperature gradient value, second temperature gradient value, unit time, etc. involved in the plate processing method can be set and selected by those skilled in the art according to the actual situation, and will not be described in detail here.

[0071] Furthermore, the control module 6 determines the real-time temperature values ​​of the first plate surface 01 and the second plate surface 02 based on the temperature signals from the temperature sensors 5. This implemented temperature value can be the average of all temperature sensors 5, the average of some of the temperature sensors 5 (e.g., the average of temperature sensors 5 in a certain area), or the value of a single temperature sensor 5 at a specific location.

[0072] The above description is only a partial preferred embodiment of this application and is not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.

A method for processing sheet metal, characterized in that, Welding operations are performed on the sheet metal using the sheet metal processing control system according to any one of claims 1 to 6; the sheet metal processing method includes: S11, The control module (6) controls the working of the medium source device (3) to deliver a medium at a predetermined temperature into the first flow circuit and the second flow circuit so as to raise the temperature of the plates on both sides of the weld seam. S12. When the temperature signal from the temperature sensor (5) determines that the real-time temperature values ​​of the first plate surface (01) and the second plate surface (02) reach the first threshold, the control module (6) controls the processing device (4) to move along the first track (1) and the second track (2) and welds the weld seam. S13. During the welding process, when the control module (6) determines that the real-time temperature value is greater than the second threshold by the temperature signal of the temperature sensor (5), the control medium source device (3) outputs a medium with a temperature lower than the second threshold, which absorbs the plate temperature through the first flow loop and the second flow loop to reduce the plate temperature; the second threshold is greater than the first threshold. S14. The control module (6) determines, through the temperature signal of the temperature sensor (5), that when the real-time temperature values ​​of the first plate surface (01) and the second plate surface (02) drop to the first threshold, the medium source device (3) is stopped. S15. The control module (6) monitors the temperature of the temperature sensor (5) in real time and repeats steps S13 to S15 until the welding is completed. S16. After welding is completed, the control module (6) controls the medium source device (3) to work and deliver the medium to the first flow circuit and the second flow circuit. The temperature of the medium decreases by the first temperature gradient value after a unit time interval, so that the temperature of the plates on both sides of the weld seam gradually decreases to room temperature in the form of gradient decrease.
