[0002] Aluminum profile production refers to the manufacturing process of forming aluminum profile products by extruding, cooling and cutting aluminum profile raw materials. It is mainly used in construction, transportation, electronics and electrical appliances and mechanical equipment.
[0003] In related technologies, during the production of aluminum profiles, the raw aluminum profiles are usually cut into specified sizes, and then the cut raw aluminum profiles are fed into an extrusion molding equipment. The extrusion molding equipment extrudes the aluminum profile products, and then the aluminum profile products are cooled down. Finally, the aluminum profile products are cut to specified lengths to complete the production of aluminum profiles.
[0004] Regarding the aforementioned technologies, when cutting aluminum profiles, the cutting point is usually measured directly on the aluminum profile after cooling and then cut at the specified length. However, due to the effects of extrusion molding, temperature, and environment, aluminum profiles often experience residual stress release, causing deformation after being cut to the specified length and stored for a certain period of time.

[0025] To make the purpose, technical solution, and advantages of this application clearer, the following description is provided in conjunction with the appendix. Figures 1 to 8 The present application will be further described in detail below with reference to embodiments. It should be understood that the specific embodiments described herein are for illustrative purposes only and are not intended to limit the scope of the application.
[0026] Reference Figure 1 This application discloses a method for producing aluminum profiles, including the following steps: Step S100: Collect the production process parameters, product composition parameters and current product temperature of the preset aluminum profile product.
[0027] Among them, aluminum profile products refer to products made from aluminum profile raw materials that are cut to a specified size, extruded and formed by extrusion equipment, and then cooled. After cooling, aluminum profile products are cut to a specified length to complete the production process.
[0028] Production process parameters refer to the process parameters of aluminum profile products during production, including extrusion speed, extrusion temperature, and cooling rate. These parameters are obtained by detecting raw data using sensors such as speed sensors, temperature sensors, and timers, and then cleaning the data. Extrusion temperature and speed affect the grain formation of aluminum profile products, while uneven cooling rates can lead to excessive thermal stress. Therefore, determining the extrusion speed, extrusion temperature, and cooling rate provides data support for subsequent analysis of how these production process parameters affect the release of residual stress.
[0029] Product composition parameters refer to the different components and their corresponding contents in aluminum profile products. Only aluminum and alloying elements such as magnesium and silicon are considered; impurity elements, such as iron, are not included. The composition content table is generated by sampling aluminum profile products and analyzing them using inductively coupled plasma optical emission spectrometry (ICP-OES). Different components have different effects on the thermal expansion of aluminum profiles. For example, excessively high contents of magnesium, silicon, and copper will reduce the coefficient of thermal expansion. Therefore, determining the product composition parameters provides data support for subsequent analysis of the specific impact of product components on product deformation.
[0030] The current product temperature refers to the temperature of the aluminum profile product before cutting, which is detected by a temperature sensor. The temperature difference between the cooled aluminum profile product and the ambient temperature will cause delayed thermal deformation of the aluminum profile product. Therefore, by determining the current product temperature, data support is provided for subsequent analysis of the specific impact of product temperature on product deformation.
[0031] Step S101: Analyze the production process parameters, product composition parameters, and current product temperature to generate a length deformation compensation coefficient.
[0032] The length deformation compensation coefficient refers to the proportion of length deformation caused by residual stress release and delayed thermal deformation in aluminum profile products. It is determined by the processing terminal after analyzing production process parameters, product composition parameters, and the current product temperature. Specific methods are detailed in [reference needed]. Figure 2 The steps.
[0033] Step S102: Collect the specified cutting length of the aluminum profile product.
[0034] The specified cutting length refers to the length that the aluminum profile product needs to be cut after cooling. The specific value is determined by the operator based on the actual needs of the aluminum profile product and entered into the processing terminal.
[0035] Step S103: Correct the specified cutting length according to the length deformation compensation coefficient to generate the actual cutting length of the aluminum profile product.
[0036] The actual cutting length refers to the cutting length after considering the release of residual stress and delayed thermal deformation of the aluminum profile. It is calculated by multiplying the length deformation compensation coefficient (calculated by the processing terminal) with the specified cutting length to obtain the deformation length. The sum of the deformation length and the specified cutting length is then calculated to obtain the actual cutting length. By adding the deformation length to the specified cutting length, it is ensured that the aluminum profile is cut to the actual cutting length and, after a certain storage period, the length of the aluminum profile meets the usage requirements.
[0037] Step S104: Cut the aluminum profile product using the preset profile cutting equipment according to the actual cutting length.
[0038] In this process, after determining the actual cutting length, the processing terminal controls the roller conveyor assembly to move the aluminum profile product toward the profile cutting equipment. The laser rangefinder detects the forward distance of the aluminum profile product. Once the forward distance equals the actual cutting length, the clamping assembly clamps and fixes the aluminum profile product, thereby controlling the profile cutting equipment to cut the aluminum profile product and obtain the required aluminum profile product.
[0039] Profile cutting equipment refers to equipment used to cut aluminum profile products, such as CNC cutting machines or laser cutting machines.
[0040] Reference Figure 2 The steps for analyzing production process parameters, product composition parameters, and current product temperature to generate a length deformation compensation coefficient include: Step S200: Collect ambient temperature and product storage time.
[0041] Among them, ambient temperature refers to the temperature within the cutting space of the aluminum profile product, which is detected by a temperature sensor and used to quantify the effect of temperature on deformation.
[0042] Product storage time refers to the time from when the aluminum profile product is cut to when it is used. It is the storage time after the aluminum profile product is cut. It is determined by the operator according to the production and usage plan and entered into the processing terminal for subsequent quantitative determination of the release ratio of residual stress.
[0043] Step S201: Calculate the difference between the current product temperature and the ambient temperature to generate the deformation effect temperature.
[0044] Among them, the deformation-affected temperature refers to the temperature value that affects the deformation of aluminum profiles, which is obtained by calculating the difference between the current product temperature and the ambient temperature at the processing terminal.
[0045] Step S202: Analyze the product composition parameters, deformation-affected temperature, and product storage time to generate the temperature-affected deformation coefficient.
[0046] Among them, the temperature-dependent deformation coefficient refers to the proportion of the influence of temperature on the deformation amplitude of aluminum profile products. It is obtained by analyzing the product composition parameters, deformation-dependent temperature, and product storage time at the processing terminal. The specific method is described in [reference needed]. Figure 3 The steps.
[0047] Step S203: Analyze the product composition parameters and the preset composition stress influence coefficient to generate the composition influence deformation coefficient.
[0048] Among them, the component stress influence coefficient refers to the proportion of the influence of different components on the stress release of aluminum profiles. For example, silicon is 0.00012 and magnesium is 0.00008. It is obtained by linear fitting of component content and deformation amplitude through orthogonal experiments.
[0049] The component influence deformation coefficient refers to the proportion of the influence of all components on the deformation range of aluminum profile products. The processing terminal finds the corresponding stress influence coefficient in the component stress influence coefficient according to the component type in the product component parameters, and then calculates the product of the component content in the product component parameters and the stress influence coefficient to obtain the influence deformation coefficient of a single component. The sum of the influence deformation coefficients of the single components is calculated to obtain the component influence deformation coefficient.
[0050] Step S204: Analyze the production process parameters and the preset process stress influence coefficient to generate the process influence deformation coefficient.
[0051] The process stress influence coefficient refers to the proportion of influence of process parameters on the stress release of aluminum profiles, including the influence of extrusion speed, and is 2.5 × 10⁻⁶. -6 The influence ratio of extrusion temperature is 1.8 × 10⁻⁶. -7 The influence ratio of cooling rate is 3.2 × 10⁻⁶. -6 .
[0052] The process influence deformation coefficient refers to the proportion of the influence of process parameters on the deformation range of aluminum profile products. It is obtained by multiplying the influence proportion of different process parameters in the process stress influence coefficient calculated by the processing terminal with the specific process parameter value in the production process parameters. The sum of the influence proportions of the single process is then calculated to obtain the process influence deformation coefficient.
[0053] Step S205: Analyze the deformation coefficients affected by temperature, composition, and process to generate a length deformation compensation coefficient.
[0054] The length deformation compensation coefficient in this step is consistent with the length deformation compensation coefficient in step S101. It is obtained by the processing terminal after analyzing the deformation coefficient affected by temperature, composition, and process. The specific method is as follows: Figure 6 The steps.
[0055] Reference Figure 3 The steps for analyzing product composition parameters, deformation-affected temperature, and product storage time to generate the temperature-affected deformation coefficient include: Step S300: Analyze the product composition parameters to determine the actual coefficient of thermal expansion of the aluminum profile product.
[0056] The actual coefficient of thermal expansion refers to the coefficient of thermal expansion of aluminum profile products, that is, the relative change in length of aluminum profile products caused by a unit temperature change. It reflects the deformation characteristics of aluminum profile products with temperature, and is obtained by analyzing the product composition parameters at the processing terminal. Specific methods are detailed in [reference needed]. Figure 4Compared to a fixed coefficient of thermal expansion, the coefficient of thermal expansion obtained through component parameter analysis can eliminate the influence of different components on the coefficient of thermal expansion, further improving the accuracy of subsequent calculations on the proportion of temperature effect on deformation.
[0057] Step S301: Analyze the product storage time to determine the deformation attenuation coefficient.
[0058] The deformation attenuation coefficient refers to the coefficient that reduces the temperature deformation amplitude of aluminum profile products due to storage time. Its value ranges from 0 to 1 and is obtained by analyzing the product's storage time using the processing terminal. Specific methods are detailed in [reference needed]. Figure 5 The steps involve fitting the residual stress release pattern using the deformation attenuation coefficient, converting the influence of temperature on deformation into a dynamic form, and avoiding the staticization of the temperature influence, which would lead to over-calculation of the temperature's effect on deformation.
[0059] Step S302: Calculate the product of the deformation-affected temperature, the actual thermal expansion coefficient, and the deformation attenuation coefficient to generate the temperature-affected deformation coefficient.
[0060] In this step, the temperature-affected deformation coefficient is consistent with that in step S202. The processing terminal calculates the product of the deformation-affected temperature and the actual thermal expansion coefficient to obtain the degree of influence of static temperature change on deformation. Then, it is multiplied by the deformation attenuation coefficient to convert the static temperature influence into a dynamic temperature influence, thus ensuring the accuracy of the temperature-affected deformation coefficient.
[0061] Reference Figure 4 The steps for analyzing product composition parameters to determine the actual coefficient of thermal expansion of aluminum profiles include: Step S400: Determine the components that affect expansion and their actual content based on the product composition parameters.
[0062] Among them, the components that affect the expansion coefficient are the components in aluminum profile products that affect the expansion coefficient, including magnesium, silicon, copper, etc. They are identified and retrieved by the processing terminal from the product component parameters. The specific identification criteria are determined by the operator. For example, the change in the expansion coefficient caused by the change in a unit component must be greater than the preset change threshold.
[0063] The actual content of a component refers to the content of the component that affects the coefficient of thermal expansion. After determining the component that affects the expansion, the content of this type of component is identified in the product component parameters.
[0064] By identifying the components that affect expansion and their actual content, we can provide data support for subsequent corrections to a fixed coefficient of thermal expansion.
[0065] Step S401: Find the corresponding component expansion correction coefficient in the preset component expansion relationship based on the component that affects expansion.
[0066] Among them, the component expansion relationship refers to the correspondence between different components and component expansion correction coefficients. For example, silicon is 0.12, magnesium is 0.08, and copper is 0.05. This is obtained by operators through orthogonal experiments, and a mapping table is formed to correspond the components one-to-one with the component expansion correction coefficients.
[0067] The component expansion correction factor refers to the correction ratio of the coefficient of thermal expansion per unit content of a component. It is obtained by the processing terminal by looking up the component that affects expansion in the mapping table corresponding to the component expansion relationship.
[0068] Step S402: Analyze the actual content of the components and the component expansion correction coefficient to determine the thermal expansion correction coefficient.
[0069] Among them, the thermal expansion correction coefficient refers to the correction ratio of the thermal expansion coefficient based on the composition of the aluminum profile product. The actual content of the composition and the composition expansion correction coefficient are calculated by the processing terminal to obtain the actual influence of the aluminum profile product composition on the thermal expansion coefficient. The total influence is obtained by summing the influence levels, and then the difference between 1 and the total influence level is calculated to obtain the thermal expansion correction coefficient.
[0070] Step S403: Calculate the product of the thermal expansion correction coefficient and the preset reference thermal expansion coefficient to generate the actual thermal expansion coefficient.
[0071] In this step, the actual thermal expansion coefficient is consistent with that in step S300. It is obtained by multiplying the thermal expansion correction coefficient and the preset reference thermal expansion coefficient by the processing terminal. The reference thermal expansion coefficient is corrected by the thermal expansion correction coefficient to take into account the influence of the composition of the aluminum profile product on the thermal expansion coefficient, thereby ensuring the accuracy of the actual thermal expansion coefficient.
[0072] Reference Figure 5 The steps for analyzing product storage time to determine the deformation attenuation coefficient include: Step S500: Substitute the product storage time into the preset deformation attenuation formula for calculation to generate the deformation attenuation intensity.
[0073] Among them, the deformation attenuation formula refers to the formula that quantifies the relationship between deformation attenuation intensity and time, reflecting the law of residual stress release. In the embodiments of this application, the logarithmic function after time plus 1 is used as the deformation attenuation formula. The use of the logarithmic function conforms to the law that the deformation attenuation intensity decreases with time.
[0074] Deformation attenuation strength refers to a coefficient that quantifies the deformation attenuation law of aluminum profile products after storage time. It is calculated by the processing terminal by substituting the product storage time into the deformation attenuation formula. The deformation attenuation strength decreases with time. The deformation attenuation strength quantifies this decreasing law and provides data support for subsequent calculation of the attenuation ratio after storage time.
[0075] Step S501: Calculate the product of deformation attenuation intensity and preset intensity adjustment factor to generate time-affected attenuation coefficient.
[0076] The strength adjustment factor refers to the specific adjustment coefficient of the deformation attenuation ratio according to the law of deformation attenuation decreasing with time. The law of deformation attenuation strength decreasing with time is specifically mapped to the ratio of deformation attenuation of aluminum profile products after changing with time. In this embodiment, 0.005 is used as an example.
[0077] The time-dependent attenuation coefficient refers to the specific impact of storage time on the deformation attenuation ratio, which is obtained by calculating the product of deformation attenuation intensity and intensity adjustment factor by the processing terminal.
[0078] Step S502: Calculate the difference between the preset reference attenuation coefficient and the time-affected attenuation coefficient to generate the deformation attenuation coefficient.
[0079] In this step, the deformation attenuation coefficient is the same as that in step S301. It is obtained by the processing terminal calculating the difference between the reference attenuation coefficient and the time-affected attenuation coefficient, thereby quantifying the temperature deformation amplitude attenuation ratio of the aluminum profile product. The final deformation attenuation coefficient is obtained by subtracting the attenuation ratio from the initial ratio.
[0080] The reference attenuation coefficient refers to the attenuation coefficient of the temperature deformation amplitude of aluminum profile products after cooling. Theoretically, it is 1, which is the temperature deformation amplitude attenuation coefficient when there is no attenuation.
[0081] Reference Figure 6 The steps for analyzing the deformation coefficients affected by temperature, composition, and process to generate the length deformation compensation coefficient include: Step S600: Integrate the deformation coefficients affected by temperature, composition, and process to generate a deformation coefficient with multiple overlapping effects.
[0082] Among them, the deformation coefficient influenced by multiple overlapping factors refers to the comprehensive influence coefficient of temperature, composition, and process on the deformation range of aluminum profile products. It reflects the proportion of change in the deformation range of aluminum profile products from the production process to storage. It is obtained by integrating the deformation coefficients affected by temperature, composition, and process at the processing terminal. The specific method is described in [reference needed]. Figure 7The steps involve assessing the deformation coefficient by considering the overlapping effects of multiple factors. This not only evaluates the deformation range of aluminum profile products from a single-dimensional perspective but also analyzes the additional effects under the combined influence of single-dimensional data through the coupling effect, thereby ensuring the accuracy of the deformation coefficient influenced by the overlapping effects of multiple factors.
[0083] Step S601: Collect the required storage time for aluminum profile products.
[0084] The required storage time refers to the time that aluminum profiles need to be stored after being cut to a specified length. This specific time is determined by the operator based on the production and usage plans and input into the processing terminal. The longer the required storage time, the more residual stress is released, and correspondingly, the greater the deformation of the aluminum profile. Defining the required storage time provides data support for subsequently quantifying the deformation range of specific aluminum profiles corresponding to the release of residual stress.
[0085] Step S602: Analyze the required storage time to determine the residual stress release ratio.
[0086] The residual stress release ratio refers to the proportion of stress released from the aluminum profile product parameters within the required storage time. This ratio is determined by the processing terminal after analyzing the required storage time. Specific methods are detailed in [reference needed]. Figure 8 The more residual stress is released, the greater the deformation amplitude. Therefore, the proportion of residual stress release can be defined as the proportion of deformation amplitude, and the maximum proportional value of the deformation amplitude of aluminum profile can be determined by the proportion of residual stress release.
[0087] Step S603: Calculate the product of the deformation coefficient and the residual stress release ratio caused by the overlapping effects of multiple factors to generate the length deformation compensation coefficient.
[0088] In this step, the length deformation compensation coefficient is the same as that in step S205. It is obtained by the processing terminal by multiplying the deformation coefficient affected by multiple factors and the residual stress release ratio. The influence coefficient on the deformation amplitude of the aluminum profile product is determined by the deformation coefficient affected by multiple factors, and the proportion of the deformation amplitude of the aluminum profile product is determined by the residual stress release ratio. The product of the influence coefficient and the proportion value is then calculated to obtain the proportion of the deformation amplitude of the final aluminum profile product, which is the length deformation compensation coefficient.
[0089] Reference Figure 7 The steps for integrating the deformation coefficients affected by temperature, composition, and process to generate a multi-factor overlapping influence coefficient include: Step S700: Calculate the sum of the deformation coefficients affected by temperature, composition, and process to generate the basic overlap coefficient.
[0090] Among them, the basic overlap influence coefficient refers to the influence coefficient of temperature, composition and process on the deformation range of aluminum profile products from the perspective of only one dimension influence. It is obtained by the sum of the temperature influence deformation coefficient, composition influence deformation coefficient and process influence deformation coefficient calculated by the processing terminal.
[0091] Step S701: Calculate the product of the temperature-induced deformation coefficient, the process-induced deformation coefficient, and the preset temperature-process coupling coefficient to generate the temperature-process coupling influence coefficient.
[0092] Among them, the temperature-process coupling coefficient refers to the coefficient that quantifies the intensity of the additional influence of temperature and process on the deformation amplitude. In this embodiment, 0.3 is used as an example. It is determined by the operator through orthogonal experiments and linear regression analysis. The process determines the total amount of residual stress, while the temperature determines the stress release rate and proportion. The coupling effect of the two is reflected in the fact that the greater the residual stress generated by the process, the greater the influence of temperature on deformation.
[0093] The temperature-process coupling influence coefficient refers to the additional influence coefficient of temperature and process on the deformation amplitude of aluminum profile products. It is obtained by multiplying the temperature-influenced deformation coefficient, the process-influenced deformation coefficient, and the temperature-process coupling coefficient calculated by the processing terminal. By using the temperature-process coupling influence coefficient, the additional influence of the coupling effect of process and temperature on the deformation amplitude is considered, ensuring the accuracy of the multi-factor overlapping influence coefficient.
[0094] Step S702: Calculate the product of the component-influence deformation coefficient, the process-influence deformation coefficient, and the preset component-process coupling coefficient to generate the component-process coupling influence coefficient.
[0095] Among them, the component-process coupling coefficient refers to the coefficient that quantifies the intensity of the additional influence of the component and process on the deformation amplitude. In this embodiment, 0.25 is used as an example. It is determined by the operator through orthogonal experiments and linear regression analysis. The component determines the difficulty of stress release, and the process determines whether the difficulty of stress release is reduced. The coupling effect of the two is reflected in the fact that the more the process matches the component, the lower the difficulty of stress release and the greater the deformation.
[0096] The composition-process coupling influence coefficient refers to the additional influence coefficient of composition and process on the deformation range of aluminum profile products. It is obtained by multiplying the composition-influence deformation coefficient, the process-influence deformation coefficient, and the composition-process coupling coefficient by the processing terminal. By considering the additional influence of process and composition coupling effect on deformation range, the accuracy of the multi-factor overlapping influence coefficient is ensured.
[0097] Step S703: Calculate the sum of the basic overlap influence coefficient, the temperature process coupling influence coefficient, and the composition process coupling influence coefficient to generate the multi-factor overlap influence coefficient.
[0098] In this step, the multi-factor overlap influence coefficient is consistent with the multi-factor overlap influence coefficient in step S600. It is obtained by the sum of the basic overlap influence coefficient, the temperature process coupling influence coefficient, and the composition process coupling influence coefficient calculated by the processing terminal. Through the multi-factor overlap influence coefficient, not only is the individual influence of single-dimensional factors on the deformation amplitude quantified, but also the additional influence of dimensional factors with coupling effects on the deformation amplitude is quantified, thereby ensuring the accuracy of the multi-factor overlap influence coefficient.
[0099] Reference Figure 8 The steps for analyzing the required storage time to determine the residual stress release ratio include: Step S800: Substitute the required storage time into the preset stress attenuation model for calculation to generate the stress release ratio affected by time.
[0100] The stress attenuation model is a model that describes the change in the proportion of stress release over time, and its specific expression is as follows: .
[0101] in, The stress release ratio is affected by time. 24 represents the required storage time, and 24 is the characteristic time constant. The stress decay model uses an exponential function to reflect the law that during stress release, the initial release rate is rapid, and the release gradually stabilizes in the later stages.
[0102] The time-dependent stress release ratio refers to the proportion of stress release caused by storage time, which is calculated by the processing terminal by substituting the required storage time into the stress attenuation model.
[0103] Step S801: Calculate the product of the time-affected stress release ratio and the preset stress release ratio threshold to generate the residual stress release ratio.
[0104] The stress release ratio threshold refers to the maximum ratio of stress release after storage for a sufficient period of time; in this embodiment, 0.92 is used as an example.
[0105] The residual stress release ratio in this step is consistent with the residual stress release ratio in step S602.
