Description

Technical Field

[0001] The present application relates to the technical field of aluminum profile quenching, and in particular to a method and system for optimizing the quenching time of aluminum profiles. Background Art

[0002] On the aluminum profile production line, the aluminum profiles after extrusion need to be quenched. Specifically, the specific process of the quenching treatment is: first, the aluminum profile is heated to a specific solid solution temperature, and then the aluminum profile is cooled.

[0003] Existing quenching treatment uses fixed cooling parameters and cooling time to cool aluminum profiles. Due to the significant difference in wall thickness of different areas of the aluminum profile, the use of fixed cooling parameters and cooling time will result in uneven cooling effect of the aluminum profile, that is, the cooling effect of different areas of the aluminum profile is different. For example, the thin-walled area dissipates heat quickly and has a good cooling effect, while the thick-walled area dissipates heat slowly and has a poor cooling effect. This uneven cooling effect will lead to inconsistent structural transformations in different areas of the aluminum profile, thereby forming uneven stress distribution (residual stress) inside the aluminum profile. Therefore, the existing technology has the problem that the use of fixed cooling parameters and cooling time to cool the aluminum profile will form residual stress, which will cause additional and unpredictable deformation of the aluminum profile in subsequent processing links, increase processing difficulty and scrap rate, and reduce the fatigue strength and stress corrosion resistance of the aluminum profile, thereby affecting the service life and safety of the aluminum profile.

[0004] There is no effective technical solution to the above problems. It should be noted that the above information disclosed in this section is only used to understand the background of the present invention, and therefore may contain information that does not constitute prior art. Summary of the Invention

[0005] The purpose of this application is to provide a method and system for optimizing the quenching time of aluminum profiles, which can effectively solve the problem that residual stress will be formed when cooling aluminum profiles using fixed cooling parameters and cooling time, resulting in additional and unpredictable deformation of aluminum profiles in subsequent processing links, increased processing difficulty and scrap rate, and decreased fatigue strength and stress corrosion resistance of aluminum profiles.

[0006] In a first aspect, the present application provides a method for optimizing the quenching time of an aluminum profile, which is applied to a quenching device including multiple cooling components. The method for optimizing the quenching time of an aluminum profile comprises the following steps: S1. Obtaining material type information and wall thickness distribution characteristics of the aluminum profile to be processed, and then dividing the aluminum profile to be processed into multiple quenching zones according to the wall thickness distribution characteristics, each quenching zone corresponding to at least one cooling assembly; S2. Obtain the actual temperature information of each quenching zone and determine the target temperature of all quenching zones based on the material type information; S3. For each quenching zone, obtain the target cooling parameters and target cooling time of the cooling assembly corresponding to the quenching zone based on the deviation between the actual temperature information and the target temperature, the material type information and the corresponding profile wall thickness; S4. Control the corresponding cooling components to cool the quenching area according to the target cooling parameters and the target cooling time.

[0007] The present application provides a method for optimizing the quenching time of aluminum profiles. The method first divides the aluminum profile to be processed into multiple quenching zones according to the wall thickness distribution characteristics, determines the target temperature of all quenching zones according to the material type information, and then, for each quenching zone, obtains the target cooling parameters and target cooling time of the cooling component corresponding to the quenching zone according to the deviation between the actual temperature information and the target temperature, the material type information and its corresponding profile wall thickness. Finally, the corresponding cooling component is controlled to cool the quenching zone according to the target cooling parameters and target cooling time. That is, the present application is equivalent to dynamically determining the cooling parameters and cooling time of different wall thickness zones according to the specific states of different wall thickness zones, that is, the present application uses different cooling parameters and cooling times to cool the aluminum profile in different zones. Therefore, the present application can effectively solve the problem that the use of fixed cooling parameters and cooling time to cool the aluminum profile will form residual stress, resulting in additional and unpredictable deformation of the aluminum profile in subsequent processing links, increased processing difficulty and scrap rate, and decreased fatigue strength and stress corrosion resistance of the aluminum profile, thereby effectively extending the service life of the aluminum profile and improving the safety of the aluminum profile.

[0008] In a second aspect, the present application further provides an aluminum profile quenching time optimization system, which is applied to a quenching device including multiple cooling components. The aluminum profile quenching time optimization system includes: A region division module is used to obtain material type information and wall thickness distribution characteristics of the aluminum profile to be processed, and then divide the aluminum profile to be processed into multiple quenching regions according to the wall thickness distribution characteristics, each quenching region corresponding to at least one cooling assembly; The target temperature determination module is used to obtain the actual temperature information of each quenching zone and determine the target temperature of all quenching zones according to the material type information; A cooling target confirmation module is used to obtain the target cooling parameters and target cooling time of the cooling assembly corresponding to each quenching zone based on the deviation between the actual temperature information and the target temperature, the material type information and the corresponding profile wall thickness; The quenching module is used to control the corresponding cooling components to cool the quenching area according to the target cooling parameters and the target cooling time.

[0009] The present application provides an aluminum profile quenching time optimization system, which first divides the aluminum profile to be processed into multiple quenching zones according to the wall thickness distribution characteristics, determines the target temperature of all quenching zones according to the material type information, and then, for each quenching zone, obtains the target cooling parameters and target cooling time of the cooling component corresponding to the quenching zone according to the deviation between the actual temperature information and the target temperature, the material type information and its corresponding profile wall thickness. Finally, the corresponding cooling component is controlled to cool the quenching zone according to the target cooling parameters and target cooling time. That is, the present application is equivalent to dynamically determining the cooling parameters and cooling time of different wall thickness zones according to the specific states of different wall thickness zones, that is, the present application uses different cooling parameters and cooling times to cool the aluminum profile in different zones. Therefore, the present application can effectively solve the problem that the use of fixed cooling parameters and cooling time to cool the aluminum profile will form residual stress, resulting in additional and unpredictable deformation of the aluminum profile in subsequent processing links, increased processing difficulty and scrap rate, and decreased fatigue strength and stress corrosion resistance of the aluminum profile, thereby effectively extending the service life of the aluminum profile and improving the safety of the aluminum profile.

[0010] As can be seen from the above, the present application provides a method and system for optimizing the quenching time of aluminum profiles. First, the aluminum profile to be processed is divided into multiple quenching zones according to the wall thickness distribution characteristics, and the target temperature of all quenching zones is determined according to the material type information. Then, for each quenching zone, the target cooling parameters and target cooling time of the cooling component corresponding to the quenching zone are obtained according to the deviation between the actual temperature information and the target temperature, the material type information and its corresponding profile wall thickness. Finally, the corresponding cooling component is controlled to cool the quenching zone according to the target cooling parameters and target cooling time. That is, the present application is equivalent to dynamically determining the cooling parameters and cooling time of different wall thickness zones according to the specific states of different wall thickness zones, that is, the present application uses different cooling parameters and cooling times to cool the aluminum profile in different zones. Therefore, the present application can effectively solve the problem that the use of fixed cooling parameters and cooling time to cool the aluminum profile will form residual stress, resulting in additional and unpredictable deformation of the aluminum profile in subsequent processing links, increased processing difficulty and scrap rate, and decreased fatigue strength and stress corrosion resistance of the aluminum profile, thereby effectively extending the service life of the aluminum profile and improving the safety of the aluminum profile.

[0014] The technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all of the embodiments. The components of the embodiments of the present application generally described and shown in the drawings here can be arranged and designed in various different configurations. Therefore, the following detailed description of the embodiments of the present application provided in the drawings is not intended to limit the scope of the application for protection, but merely represents the selected embodiments of the present application. Based on the embodiments of the present application, all other embodiments obtained by those skilled in the art without making creative work fall within the scope of protection of the present application.

[0015] It should be noted that similar reference numerals and letters represent similar items in the following drawings. Therefore, once an item is defined in one drawing, it does not need to be further defined or explained in subsequent drawings. At the same time, in the description of this application, the terms "first", "second", etc. are only used to distinguish the description and should not be understood as indicating or implying relative importance.

[0016] In conventional aluminum profile production lines, extruded aluminum profiles require quenching. Specifically, the quenching process involves heating the aluminum profile to a specific solution temperature and then cooling it. Existing quenching processes utilize fixed cooling parameters and times. However, due to the significant differences in wall thickness across different regions of an aluminum profile, using fixed cooling parameters and times results in uneven cooling. For example, thin-walled areas dissipate heat quickly and achieve good cooling, while thick-walled areas dissipate heat slowly and achieve poor cooling. This difference in cooling results in residual stresses within the aluminum profile after quenching. Consequently, existing technologies face the problem of using fixed cooling parameters and times to cool aluminum profiles, which can lead to additional and unpredictable deformation in subsequent processing steps, increase processing difficulty and scrap rates, and reduce the fatigue strength and stress corrosion resistance of the aluminum profile, impacting the service life and safety of the aluminum profile.

[0017] For example, consider quenching an aluminum profile with a complex cross-section and uneven wall thickness distribution (such as an I-beam or channel profile) in a quenching machine with multiple cooling components. In existing technology, the equipment sets a fixed set of cooling parameters (such as the spray flow rate and pressure of the cooling medium) and cooling time, and then cools the entire aluminum profile. In this scenario, the thin-walled areas of the aluminum profile, due to their low heat capacity and relatively large heat dissipation area, will quickly reach the target temperature and may even overcool. However, the thick-walled areas, due to their large heat capacity and relatively slow heat dissipation, will cool significantly slower, making it difficult to reach the required cooling rate or target temperature within the specified time. This difference in cooling rate and final temperature between different areas can lead to uneven shrinkage and phase transformation within the aluminum profile, resulting in significant residual stresses.

[0018] If these issues are not addressed, the residual stress within the aluminum profile will be released during subsequent machining (such as cutting, milling, and drilling), causing unpredictable warping, bending, or torsional deformation of the aluminum profile, seriously affecting machining accuracy and product dimensional stability. This will not only increase the difficulty of subsequent processing, potentially requiring additional shaping steps, but will also significantly increase scrap rates and increase production costs. Furthermore, residual stress can reduce the fatigue strength and stress corrosion resistance of the aluminum profile, making it more susceptible to fatigue crack propagation or stress corrosion cracking during long-term use or under specific environments, thereby shortening the aluminum profile's service life and posing a potential threat to its safety.

[0019] In this regard, firstly, Figure 1 As shown, the present application provides a method for optimizing the quenching time of aluminum profiles, which is applied to a quenching device including multiple cooling components. The method for optimizing the quenching time of aluminum profiles includes the following steps: S1. Obtaining material type information and wall thickness distribution characteristics of the aluminum profile to be processed, and then dividing the aluminum profile to be processed into multiple quenching zones according to the wall thickness distribution characteristics, each quenching zone corresponding to at least one cooling assembly; S2. Obtain the actual temperature information of each quenching zone and determine the target temperature of all quenching zones based on the material type information; S3. For each quenching zone, obtain the target cooling parameters and target cooling time of the cooling assembly corresponding to the quenching zone based on the deviation between the actual temperature information and the target temperature, the material type information and the corresponding profile wall thickness; S4. Control the corresponding cooling components to cool the quenching area according to the target cooling parameters and the target cooling time.

[0020] Among them, the aluminum profile quenching time optimization method provided in this embodiment is applied in a quenching equipment including multiple cooling components, which are preferably existing liquid cooling components. The multiple cooling components of this embodiment are independent of each other, that is, this embodiment can make the cooling effects of different cooling components different.

[0021] The aluminum profile to be processed in step S1 is an aluminum profile that needs to be quenched. The material type information of this embodiment is the type of the aluminum profile to be processed. Since in the aluminum profile production process, the material type is usually clearly specified in the production plan and recorded in the production management system, this embodiment can obtain the material type information of the aluminum profile to be processed by interacting with the production management system. When the type of the aluminum profile is pre-written in the barcode or RFID tag of the aluminum profile, this embodiment can obtain the material type information of the current aluminum profile to be processed by using a scanning or radio frequency identification device to read the tag before the aluminum profile enters the quenching process. The wall thickness distribution characteristics of this embodiment can reflect the wall thickness of the aluminum profile to be processed at different positions. This embodiment can obtain the wall thickness distribution characteristics of the aluminum profile to be processed by first scanning the aluminum profile with a three-dimensional scanner to obtain an accurate three-dimensional model of the aluminum profile, and then analyzing the wall thickness data of each position of the aluminum profile according to the three-dimensional model. This embodiment can also obtain the wall thickness distribution characteristics of the aluminum profile to be processed by performing non-contact measurement of the surface of the aluminum profile using equipment such as an ultrasonic thickness gauge or an eddy current thickness gauge to obtain the wall thickness data of each position. Since the wall thickness distribution characteristics of the aluminum profile may already exist in the design drawings or CAD models, this embodiment can also obtain the wall thickness distribution characteristics of the aluminum profile to be processed by directly extracting wall thickness information from these data sources (design drawings or CAD models). The specific process of step S1 for dividing the aluminum profile to be processed into multiple quenching zones based on the wall thickness distribution characteristics can be as follows: first, determine one or more wall thickness thresholds, such as a thin-wall threshold, a medium-wall threshold, and a thick-wall threshold; then, based on the wall thickness distribution characteristics, divide the area with a wall thickness less than the thin-wall threshold into a thin-wall quenching zone, divide the area with a wall thickness between the thin-wall threshold and the medium-wall threshold into a medium-wall quenching zone, and divide the area with a wall thickness greater than the thick-wall threshold into a thick-wall quenching zone. Step S1 can also utilize the existing Kmeans clustering algorithm to divide the aluminum profile to be processed into multiple quenching zones based on the wall thickness distribution characteristics. It should be understood that since each quenching zone corresponds to at least one cooling component after the quenching zone division is completed, this embodiment can achieve zoned cooling of the aluminum profile.

[0022] Step S2 can utilize existing temperature sensors or infrared imagers to measure the temperature of each quenching area to obtain the actual temperature information of each quenching area. Since different types of aluminum profiles have different chemical compositions and metallographic structures, the differences in chemical composition and metallographic structure will result in different temperatures required for different types of aluminum profiles to be reached after quenching. For example, if the temperature required after quenching is improperly set, the aluminum profile will not be able to precipitate inappropriate metallographic phases during the cooling process, thereby affecting the strength, hardness, corrosion resistance and other properties of the aluminum profile. The ultimate goal of this application is to make the cooling effect of different areas of the aluminum profile consistent, that is, the temperature of different areas of the aluminum profile after quenching is the same. Therefore, this embodiment needs to determine the target temperature of all quenching areas based on the material type information, that is, the target temperature corresponding to different quenching areas is the same. Step S2 can determine the target temperature of all quenching areas according to the material type information by querying a pre-built mapping relationship table of material type and final temperature according to the material type information. Step S2 can also determine the target temperature of all quenching areas according to the material type information by inputting the material type information into a pre-trained temperature evaluation model. The temperature evaluation model can predict the temperature that the aluminum profile needs to reach after quenching treatment based on the input material type information and output the corresponding target temperature.

[0023] The working principle of step S3 is as follows: since the deviation between the actual temperature information and the target temperature directly reflects the cooling demand of the current quenching area, the greater the deviation between the actual temperature information and the target temperature, the stronger the cooling capacity required by the current quenching area (for example, a larger cooling flow or a longer cooling time); the smaller the deviation between the actual temperature information and the target temperature, the weaker the cooling capacity required by the current quenching area (for example, a smaller cooling flow or a shorter cooling time). The material type information determines the thermophysical properties of the aluminum profile, such as thermal conductivity, specific heat capacity, etc. These thermophysical properties directly affect the cooling rate, that is, different types of aluminum profiles have different cooling rates under the same The temperature change rate under cooling conditions will vary, and the profile wall thickness will affect the cooling rate of the aluminum profile. Specifically, the quenching area with a thicker profile wall has a large heat capacity and slow heat dissipation, and requires a stronger cooling capacity or a longer cooling time to cool the quenching area to the target temperature. The quenching area with a smaller profile wall thickness has a small heat capacity and fast heat dissipation, and requires a weaker cooling capacity or a shorter cooling time to avoid overcooling of the quenching area. Therefore, step S3 needs to obtain the target cooling parameters and target cooling time of the cooling component corresponding to the quenching area based on the deviation between the actual temperature information and the target temperature, the material type information and its corresponding profile wall thickness. Specifically, taking the target cooling parameters and target cooling time for a particular quenching zone as an example, step S3 can obtain the target cooling parameters and target cooling time for the cooling assembly corresponding to the quenching zone by querying a pre-established mapping table of temperature deviation, material type, profile wall thickness, cooling parameters, and cooling time based on the deviation between the actual temperature information corresponding to the quenching zone and the target temperature, material type information, and the profile wall thickness corresponding to the quenching zone. These target cooling parameters and target cooling time refer to the optimal cooling control quantities dynamically calculated for each quenching zone based on its specific state (the deviation between the actual temperature information and the target temperature, material type information, and profile wall thickness). It should be understood that since the wall thickness distribution characteristics can reflect the wall thickness of the aluminum profile to be processed at different locations, step S3 can obtain the profile wall thickness corresponding to the quenching zone based on the wall thickness distribution characteristics.

[0024] Step S4 can be achieved by sending the target cooling parameters and target cooling time to the corresponding cooling component, so that the cooling component cools the corresponding quenching area according to the received target cooling parameters and target cooling time. The corresponding cooling component is controlled to cool the quenching area according to the target cooling parameters and target cooling time. Step S4 can be an existing technology, and its working principle will not be discussed in detail here.

[0025] As a preferred embodiment, the solution of the present application is specifically implemented as follows: 1. The wall thickness distribution characteristics of the aluminum profile to be processed are obtained through three-dimensional scanning technology, and the material type information of the aluminum profile to be processed is obtained from the production management system; 2. The aluminum profile to be processed is divided into several quenching areas according to the wall thickness distribution characteristics. For example, the parts with large differences in wall thickness in the cross section are divided into different quenching areas, and a group of independently controllable spray nozzles (cooling components) are arranged below or on the side of each quenching area; 3. After the aluminum profile enters the quenching equipment, an infrared thermal imager or a distributed temperature sensor array is used to monitor the surface temperature of each quenching area in real time; 4. Then, according to the material type information, the pre-established process is consulted. Database, determine the target temperature of all quenching areas; 5. For each quenching area, use the preset mapping table or run the control algorithm to obtain the spray flow (target cooling parameter) and spray duration (target cooling time) of the corresponding spray nozzle according to the deviation between the actual temperature information and the target temperature, the material type information and its corresponding profile wall thickness. For example, for areas where the actual temperature is much higher than the target temperature, a larger spray flow and a longer spray time may be calculated; for areas where the actual temperature is close to the target temperature, a smaller flow or a shorter time may be calculated; 6. Control the spray nozzles corresponding to each quenching area to spray cooling according to the calculated spray flow and spray duration.

[0026] The present application provides a method for optimizing the quenching time of aluminum profiles. The method first divides the aluminum profile to be processed into multiple quenching zones according to the wall thickness distribution characteristics, determines the target temperature of all quenching zones according to the material type information, and then, for each quenching zone, obtains the target cooling parameters and target cooling time of the cooling component corresponding to the quenching zone according to the deviation between the actual temperature information and the target temperature, the material type information and its corresponding profile wall thickness. Finally, the corresponding cooling component is controlled to cool the quenching zone according to the target cooling parameters and target cooling time. That is, the present application is equivalent to dynamically determining the cooling parameters and cooling time of different wall thickness zones according to the specific states of different wall thickness zones, that is, the present application uses different cooling parameters and cooling times to cool the aluminum profile in different zones. Therefore, the present application can effectively solve the problem that the use of fixed cooling parameters and cooling time to cool the aluminum profile will form residual stress, resulting in additional and unpredictable deformation of the aluminum profile in subsequent processing links, increased processing difficulty and scrap rate, and decreased fatigue strength and stress corrosion resistance of the aluminum profile, thereby effectively extending the service life of the aluminum profile and improving the safety of the aluminum profile.

[0027] In some preferred embodiments, step S3 includes: S31. For each quenching zone, query a pre-built mapping relationship table of temperature deviation, material type, profile wall thickness, cooling parameter, and cooling time based on the deviation between the actual temperature information and the target temperature, the material type information, and the corresponding profile wall thickness, to obtain a first preliminary cooling parameter and a first preliminary cooling time of the cooling assembly corresponding to the quenching zone; S32. For each quenching zone, obtain oxide layer thickness information, and then query a pre-built mapping relationship table of oxide layer thickness, cooling parameter compensation amount, and cooling time compensation amount based on the oxide layer thickness information to obtain a first cooling parameter compensation amount and a first cooling time compensation amount; S33. For each quenching zone, calculate a target cooling parameter according to the corresponding first preliminary cooling parameter and the first cooling parameter compensation amount, and calculate a target cooling time according to the corresponding first preliminary cooling time and the first cooling time compensation amount.

[0028] In step S32, the oxide layer thickness information can be obtained by measuring the thickness of the oxide layer in the quenching area using an eddy current sensor or an optical measuring device. The mapping relationship table of the oxide layer thickness, the cooling parameter compensation amount, and the cooling time compensation amount in this embodiment associates the oxide layer thickness with the compensation amount required for the cooling parameter and time. Therefore, in this embodiment, the first cooling parameter compensation amount and the first cooling time compensation amount can be obtained by querying the pre-constructed mapping relationship table of the oxide layer thickness, the cooling parameter compensation amount, and the cooling time compensation amount according to the oxide layer thickness information. These compensation amounts reflect the adjustments that need to be made to the preliminary plan due to the presence of the oxide layer. In step S33, the target cooling parameter can be calculated by directly summing or weighted summing the first preliminary cooling parameter and the first cooling parameter compensation amount. In step S33, the target cooling time can be calculated by directly summing or weighted summing the first preliminary cooling time and the first cooling time compensation amount. The oxide layer on the surface of the aluminum profile affects the heat conduction efficiency, and the difference in oxide layer thickness will cause the same cooling parameters to produce different actual cooling effects. Since this embodiment can first determine the first cooling parameter compensation amount and the first cooling time compensation amount based on the oxide layer thickness information, and then calculate the target cooling parameter based on the first preliminary cooling parameter and the first cooling parameter compensation amount, and calculate the target cooling time based on the first preliminary cooling time and the first cooling time compensation amount, the preliminary determined cooling parameter and cooling time are corrected according to the oxide layer thickness. That is, this embodiment is equivalent to obtaining the target cooling parameter and target cooling time of the cooling component corresponding to the quenching area based on the deviation between the actual temperature information and the target temperature, the material type information and its corresponding profile wall thickness, and further considering the influence of the oxide layer thickness on the cooling process. Therefore, this embodiment can make the final determined target cooling parameter and target cooling time more accurately reflect the actual cooling requirements, so as to effectively improve the accuracy and reliability of the target cooling parameter and target cooling time, thereby effectively improving the accuracy and reliability of the cooling control, effectively reducing the residual stress inside the aluminum profile and improving the quenching quality, thereby effectively reducing the deformation risk and scrap rate of subsequent processing, improving the performance of the aluminum profile and extending the service life of the aluminum profile.

[0029] In some preferred embodiments, step S33 includes: S331. For each quenching zone, obtain the cumulative operating time and historical operating data set of the corresponding cooling component, and then obtain the aging degree of the cooling component based on the cumulative operating time and historical operating data set; S332: for each quenching zone, query a pre-built mapping relationship table of aging degree, cooling parameter compensation amount, and cooling time compensation amount according to the aging degree of the cooling component to obtain a second cooling parameter compensation amount and a second cooling time compensation amount; S333. For each quenching zone, calculate the target cooling parameter according to the corresponding first preliminary cooling parameter, the first cooling parameter compensation amount and the second cooling parameter compensation amount, and calculate the target cooling time according to the corresponding first preliminary cooling time, the first cooling time compensation amount and the second cooling time compensation amount.

[0030] In this embodiment, the cumulative operating time of the corresponding cooling component can be obtained by recording the cumulative working time of each cooling component in the control system. The historical operating data set of this embodiment may include data on the flow rate, pressure, temperature, energy consumption, etc. of the cooling medium that changes over time. These data can be obtained by installing sensors at key positions of the cooling component and periodically collecting them. In this embodiment, a preset threshold, a statistical analysis method, or a machine learning model can be used for evaluation to obtain the degree of aging of the cooling component based on the cumulative operating time and the historical operating data set. For example, the degree of aging of the cooling component can be evaluated by analyzing the time range of the cumulative operating time (for example, reaching a certain time is considered aging) or the rate of change of historical data in the historical operating data set (for example, abnormal patterns such as decreased cooling efficiency, increased energy consumption, and increased parameter fluctuations). The degree of aging of the cooling component can be expressed as a numerical value or a level. In this embodiment, the degree of aging of the cooling component can also be obtained by querying a pre-built mapping relationship table of operating time, operating data set, and aging degree based on the cumulative operating time and the historical operating data set. The mapping relationship table of the degree of aging, cooling parameter compensation and cooling time compensation in this embodiment can be established through experiments, simulations or historical data analysis. The mapping relationship table establishes a corresponding relationship between the degree of aging and the cooling parameter compensation and cooling time compensation, that is, the mapping relationship table can provide corresponding cooling parameter and cooling time adjustment suggestions based on the degree of aging of the cooling component. The second cooling parameter compensation and the second cooling time compensation in this embodiment are determined based on the degree of aging of the cooling component. The second cooling parameter compensation and the second cooling time compensation are used to correct the preliminary cooling parameter and preliminary cooling time to offset the decrease in cooling efficiency caused by the aging of the cooling component. This embodiment can calculate the target cooling parameter by directly summing or weighted summing the first preliminary cooling parameter, the first cooling parameter compensation and the second cooling parameter compensation. This embodiment can calculate the target cooling time by directly summing or weighted summing the first preliminary cooling time, the first cooling time compensation and the second cooling time compensation.A cooling component that has been running for a long time may have a decrease in cooling efficiency due to aging. If the quenching area is still cooled according to the target cooling parameters and target cooling time determined based on the specific state of the quenching area and the thickness of the oxide layer, the expected cooling effect cannot be achieved, thereby affecting the quenching quality of the aluminum profile. Since this embodiment can first determine the second cooling parameter compensation amount and the second cooling time compensation amount according to the aging degree of the cooling component, and then calculate the target cooling parameter according to the first preliminary cooling parameter, the first cooling parameter compensation amount and the second cooling parameter compensation amount, and calculate the target cooling time according to the first preliminary cooling time, the first cooling time compensation amount and the second cooling time compensation amount, the cooling parameter and the target cooling time can be adjusted according to the aging degree of the cooling component. The cooling time is compensated, that is, even if the cooling efficiency of the cooling component decreases, this embodiment can enable the quenching area to achieve the expected cooling effect. Therefore, this embodiment can effectively eliminate the influence of the aging of the cooling component on the cooling effect and quenching quality, that is, this embodiment can make the final determined target cooling parameters and target cooling time more accurately reflect the actual cooling requirements, so as to further improve the accuracy and reliability of the target cooling parameters and target cooling time, thereby further improving the accuracy and reliability of cooling control, so as to further reduce the residual stress inside the aluminum profile and improve the quenching quality, thereby further reducing the deformation risk and scrap rate of subsequent processing, improving the performance of the aluminum profile and extending the service life of the aluminum profile.

[0031] In some preferred embodiments, step S332 includes: A1. For each quenching zone, calculate the second preliminary cooling parameter according to the corresponding first preliminary cooling parameter, the first cooling parameter compensation amount, and the second cooling parameter compensation amount, and calculate the target cooling time according to the corresponding first preliminary cooling time, the first cooling time compensation amount, and the second cooling time compensation amount; A2. Select the quenching area with the smallest distance from the center of the aluminum profile to be processed, and then use the second preliminary cooling parameter corresponding to the quenching area as the target cooling parameter of the quenching area; A3. Select the quenching area with the smallest distance from the center of the aluminum profile to be processed among the unselected quenching areas, and obtain the cooling parameter influence value based on the target cooling parameter and target cooling time corresponding to the selected quenching areas and the minimum distance between the selected quenching areas and the currently selected quenching area; A4. Analyze whether the cooling parameter influence amount is the same as the second preliminary cooling parameter corresponding to the currently selected quenching zone. If so, set the target cooling parameter corresponding to the currently selected quenching zone to 0. If not, calculate the target cooling parameter corresponding to the currently selected quenching zone based on all cooling parameter influence amounts and the second preliminary cooling parameter. A5. Analyze whether there is an unselected quenching area. If so, return to step A2; if not, execute step S4.

[0032] The cooling parameter influence amount of this embodiment refers to the degree of influence of the quenching area on the cooling parameter requirements of other surrounding quenching areas when the quenching area is cooled under specific cooling parameters and cooling time. This embodiment can use physical model calculation, regression analysis based on historical data or machine learning model prediction to obtain the cooling parameter influence amount according to the target cooling parameters and target cooling time corresponding to the selected quenching area and the minimum distance between the selected quenching area and the currently selected quenching area. This embodiment can also query the pre-built information about the target area according to the target cooling parameters and target cooling time corresponding to the selected quenching area and the minimum distance between the selected quenching area and the currently selected quenching area. The mapping relationship table of target cooling parameters, minimum spacing and parameter influence amounts is used to obtain the cooling parameter influence amount according to the target cooling parameters and target cooling time corresponding to the selected quenching area and the minimum distance between the selected quenching area and the currently selected quenching area. It should be understood that the currently selected quenching area in step A3 is the quenching area selected in step A2. When there are multiple quenching areas currently selected, step B3 first obtains the target cooling parameters and target cooling time corresponding to each selected quenching area and the minimum distance between the selected quenching area and the currently selected quenching area to obtain the parameter influence amount, and then the sum of all parameter influence amounts is used as the cooling parameter influence amount.

[0033] This embodiment provides a cooling parameter adjustment scheme that takes into account the cooling effects between different areas of the aluminum profile. First, the second preliminary cooling parameter and target cooling time are obtained by calculation. These parameters are preliminary results after considering temperature deviation, material type, wall thickness, oxide layer thickness and aging degree compensation. Then, iterative processing of each quenching area begins, giving priority to the quenching area closest to the center of the aluminum profile, and directly using its second preliminary cooling parameter as the target cooling parameter. This is because the central area will conduct heat with the surrounding areas and the cooling of the central area usually has a greater impact on the overall performance, so its cooling effect is prioritized. Next, the mutual influence between areas is considered, and the next unselected quenching area closest to the center of the aluminum profile is selected. The cooling parameter influence amount is calculated based on the target cooling parameters, target cooling time of the selected areas and their distance from the currently selected quenching area. This influence amount reflects the degree of influence of the cooling activity of the surrounding areas on the cooling parameter requirements of the current area. Subsequently, a determination is made as to whether the calculated cooling parameter influence is identical to the second preliminary cooling parameter corresponding to the currently selected quenching zone. If so, the cooling effect of the surrounding zones on the zone has satisfied the zone's preliminary cooling requirement, and thus the target cooling parameter for the zone can be set to 0, thereby avoiding overcooling. If not, the final target cooling parameter for the current zone is calculated based on all calculated cooling parameter influences and the current zone's second preliminary cooling parameter, thereby comprehensively considering the zone's own cooling requirement and the mutual influence of the surrounding zones. This process is repeated until all quenching zones have been processed. This embodiment, through this iterative approach and consideration of the interactions between quenching zones, fully considers the influence of the cooling activity of other zones when determining the target cooling parameter for each quenching zone. This embodiment effectively avoids the situation where, due to the failure to consider the influence of other zones when determining the target cooling parameter for each quenching zone, quenching zones that do not require cooling under the influence of other target cooling parameters are cooled. This embodiment prevents certain quenching zones from being overcooled under the influence of other quenching zones, thereby effectively avoiding the situation where, due to overcooling of some quenching zones, the cooling effect of the aluminum profile is uneven, leading to the formation of residual stresses within the aluminum profile.

[0034] In some preferred embodiments, step S4 includes: S41. Acquire cooling medium status information, and then query a pre-built mapping relationship table of medium status, parameter adjustment strategy, and time adjustment strategy based on the cooling medium status information to obtain a cooling parameter adjustment strategy and a cooling time adjustment strategy; S42. Adjust the target cooling parameter according to the cooling parameter adjustment strategy, and adjust the target cooling time according to the cooling time adjustment strategy; S43. Control the corresponding cooling component to cool the quenching area according to the target cooling parameter and the target cooling time.

[0035] The cooling medium status information of this embodiment refers to data reflecting the current physical or chemical state of the cooling medium, which may include the temperature, cleanliness, flow rate, component concentration, etc. of the cooling medium. This embodiment can use existing sensors to obtain the cooling medium status information, and the cooling medium status information can reflect the current cooling capacity of the cooling medium. The mapping relationship table of the medium status, parameter adjustment strategy and time adjustment strategy of this embodiment refers to a data table that stores the correspondence between different cooling medium states and corresponding cooling parameters and time adjustment schemes. The cooling parameter adjustment strategy of this embodiment refers to the rules or algorithms for how to correct the target cooling parameters determined based on the cooling medium status information. The cooling time adjustment strategy of this embodiment refers to the rules or algorithms for how to correct the target cooling time determined based on the cooling medium status information. These strategies can compensate for the impact of changes in the cooling medium status. For example, if the cooling medium temperature is too high, the adjustment strategy may indicate increasing the spray flow rate or extending the cooling time. Changes in the state of the cooling medium will affect the cooling effect of the cooling medium, that is, changes in the state of the cooling medium may cause the actual cooling effect of the cooling component to be inconsistent with expectations. Since this embodiment first obtains the cooling parameter adjustment strategy and the cooling time adjustment strategy based on the cooling medium state information, and then adjusts the target cooling parameters according to the cooling parameter adjustment strategy and adjusts the target cooling time according to the cooling time adjustment strategy, and finally controls the corresponding cooling component to cool the quenching area according to the adjusted target cooling parameters and target cooling time, that is, this embodiment can eliminate the influence of the cooling medium state on the cooling effect of the cooling medium by dynamically adjusting the target cooling parameters and target cooling time according to the cooling medium state information. Therefore, this embodiment can effectively avoid the situation where the actual cooling effect of the cooling component is inconsistent with expectations and the cooling effect of the aluminum profile is uneven due to the change in the cooling medium state affecting the cooling effect of the cooling medium, thereby effectively reducing the deformation risk and scrap rate of subsequent processing, improving the performance of the aluminum profile and extending the service life of the aluminum profile.

[0036] In some preferred embodiments, step S43 includes: S431. Obtain a predicted cooling rate based on the target cooling parameter, and query a pre-built mapping relationship table of material type, wall thickness, and cooling rate upper limit based on the material type information and the profile wall thickness corresponding to the quenching area to obtain a preset cooling rate upper limit; S432: When the predicted cooling rate is less than or equal to the preset cooling rate upper limit, controlling the corresponding cooling component to cool the quenching area according to the target cooling parameter and the target cooling time; S433. When the predicted cooling rate is greater than the preset cooling rate upper limit, the corrected cooling time is calculated according to the predicted cooling rate, the target cooling time and the preset cooling rate upper limit, and the pre-constructed mapping relationship table of cooling rate and cooling parameters is queried according to the preset cooling rate upper limit to obtain the corrected cooling parameters, and then the corresponding cooling component is controlled to cool the quenching area according to the corrected cooling parameters and the corrected cooling time.

[0037] The predicted cooling rate of this embodiment refers to the temperature drop rate expected to be achieved in the quenching area of ​​the aluminum profile under the current target cooling parameters. This embodiment can obtain the predicted cooling rate by querying a pre-built mapping table of cooling parameters and cooling rates based on the target cooling parameters. This embodiment can also obtain the predicted cooling rate by inputting the target cooling parameters into a pre-trained cooling rate estimation model. The cooling rate estimation model can evaluate the cooling rate based on the input cooling parameters and output the corresponding predicted cooling rate. The mapping table of material type, wall thickness, and cooling rate upper limit in this embodiment stores the cooling rate upper limit corresponding to different material type and wall thickness combinations. The preset cooling rate upper limit in this embodiment is the maximum cooling rate determined based on the specific material type and profile wall thickness. It should be understood that if the aluminum profile exceeds this rate, it may have an adverse effect on the material properties. The corrected cooling time in this embodiment refers to the cooling duration recalculated to control the actual cooling rate within a safe range when the predicted cooling rate is too high. The corrected cooling parameter in this embodiment refers to the cooling parameter re-obtained based on the preset cooling rate upper limit when the predicted cooling rate is too high to control the actual cooling rate within a safe range. Since this embodiment can analyze whether the cooling rate of the quenching area is too fast by comparing the predicted cooling rate obtained by the target cooling parameters with the preset cooling rate upper limit determined based on the material type and profile wall thickness, and first correct the cooling parameters and cooling time when the cooling rate is too fast, and then use the corrected cooling parameters and cooling time to cool the quenching area, this embodiment can effectively avoid the damage to the performance of the aluminum profile material due to the excessive cooling rate, thereby effectively improving the safety and reliability of the quenching process.

[0038] In some preferred embodiments, the cooling medium status information includes the cooling medium temperature and the cooling medium cleanliness. The cooling medium temperature of this embodiment refers to the real-time temperature value of the cooling medium, which can be obtained by using a temperature sensor. The cooling medium cleanliness of this embodiment refers to the measurement of the impurity or pollutant content in the cooling medium, which can be obtained by using a turbidity sensor, a conductivity sensor or an optical sensor. The mapping relationship table of the medium status, parameter adjustment strategy and time adjustment strategy of this embodiment associates different temperature and cleanliness combinations with corresponding cooling parameters and cooling time adjustment strategies. For example, when the temperature rises, it is necessary to increase the cooling intensity or extend the cooling time; when the cleanliness decreases, it may be necessary to reduce the flow rate to avoid blockage or consider shortening the cooling time to reduce the impact of impurities.

[0039] In some preferred embodiments, the cooling assembly is a cooling medium spray assembly, and the target cooling parameters include spray flow rate and spray pressure. The cooling medium spray assembly in this embodiment refers to a device that sprays cooling medium onto an object surface in a specific manner via nozzles. This can be achieved using a variety of nozzle types and arrangements. The spray flow rate in this embodiment directly affects the amount of heat removed per unit time, while the spray pressure affects the cooling medium's atomization, penetration, and coverage.

First, the aluminum profile to be processed is divided into multiple quenching zones according to the wall thickness distribution characteristics, and the target temperature of all quenching zones is determined according to the material type information.

Finally, the corresponding cooling component is controlled to cool the quenching zone according to the target cooling parameters and target cooling time. That is, the present application is equivalent to dynamically determining the cooling parameters and cooling time of different wall thickness zones according to the specific states of different wall thickness zones, that is, the present application uses different cooling parameters and cooling times to cool the aluminum profile in different zones. Therefore, the present application can effectively solve the problem that the use of fixed cooling parameters and cooling time to cool the aluminum profile will form residual stress, resulting in additional and unpredictable deformation of the aluminum profile in subsequent processing links, increased processing difficulty and scrap rate, and decreased fatigue strength and stress corrosion resistance of the aluminum profile, thereby effectively extending the service life of the aluminum profile and improving the safety of the aluminum profile.
