In order to improve the quality of the aluminum section, the cutting saw blade can be non-disassembled and ground to improve the sharpness of the saw blade, thereby effectively improving the quality of the aluminum section.

[0004] However, there are still the following problems in the prior art:

[0005] In the prior art, aluminum profiles are not classified according to the ratio of the front and rear surface areas of the aluminum rods after being extruded into aluminum profiles, and different adjustment strategies are not adopted for aluminum profiles that are prone to surface shrinkage and bending due to temperature changes and aluminum profiles that are not prone to surface shrinkage and bending due to temperature changes, resulting in poor processing quality of aluminum profiles. Summary of the invention

[0006] To this end, the present invention provides a high-strength aluminum profile processing system to overcome the problem in the prior art that the aluminum profiles are not classified according to the ratio of the front and rear surface areas of the aluminum rods extruded into the aluminum profiles, and different adjustment strategies are not adopted for the aluminum profiles that are prone to surface shrinkage and bending due to temperature changes and the aluminum profiles that are not prone to surface shrinkage and bending due to temperature changes, resulting in poor aluminum profile processing quality.

[0007] To achieve the above object, the present invention provides a high-strength aluminum profile processing system, comprising:

[0008] An extrusion mechanism, including an oven for flame-spraying the aluminum rods, and an extruder for extruding the flame-sprayed aluminum rods into aluminum profiles;

[0009] The traction mechanism comprises a clamp for clamping the aluminum profile and a traction component connected to the clamp for pulling the clamp to move;

[0010] The detection module includes a first image acquisition unit disposed at an inlet side of the extruder for acquiring an image of the aluminum rod and a second image acquisition unit disposed at an outlet side of the extruder for acquiring an image of the aluminum profile;

[0011] A host computer, which is connected to the extrusion mechanism, the traction mechanism and the detection module respectively, and includes an analysis unit and a control unit, wherein the analysis unit is used to obtain a surface area ratio of the aluminum profile to the aluminum bar according to the aluminum bar image and the aluminum profile image, and classify the extrusion deformation category according to the surface area ratio;

[0012] The control unit is used to select an adjustment strategy for the aluminum profile according to the extrusion deformation type, including:

[0013] Dividing the aluminum profile into several segments, identifying the number of segments with deformation and the average curvature of the deformed segments, calculating deformation characterization parameters, and adjusting the stretching distance and stretching speed of the traction component according to the deformation characterization parameters;

[0014] Or, identify the maximum horizontal angle between the surface of the aluminum profile and the horizontal plane and the average vertical angle between the corresponding planes at both ends of the aluminum profile and the vertical plane, and determine whether to control the traction mechanism to perform a corrective action, wherein the corrective action includes controlling the traction mechanism to stretch the aluminum profile until the maximum horizontal angle between the surface of the aluminum profile and the horizontal plane meets a predetermined corrective threshold.

[0015] Furthermore, the analysis unit compares the surface area ratio of the aluminum profile with a preset surface area ratio comparison threshold.

[0016] If the surface area ratio of the aluminum profile is greater than the preset surface area ratio comparison threshold, the analysis unit classifies the extrusion deformation category of the aluminum profile as a strong extrusion deformation category;

[0017] If the surface area ratio of the aluminum profile is less than or equal to the preset surface area ratio comparison threshold, the analysis unit classifies the extrusion deformation category of the aluminum profile as a weak extrusion deformation category.

[0018] Furthermore, the control unit is used to select an adjustment strategy for the aluminum profile according to the type of extrusion deformation of the aluminum profile.

[0019] If the extrusion deformation category of the aluminum profile is a strong extrusion deformation category, the control unit divides the aluminum profile into a plurality of segments, identifies the number of segments with deformation and the average curvature of the deformed segments, calculates deformation characterization parameters, and adjusts the stretching distance and stretching speed of the traction component according to the deformation characterization parameters;

[0020] If the extrusion deformation category of the aluminum profile is a weak extrusion deformation category, the control unit identifies the maximum horizontal angle between the surface of the aluminum profile and the horizontal plane and the average vertical angle between the corresponding planes at both ends of the aluminum profile and the vertical plane, and determines whether to control the traction mechanism to perform a corrective action, wherein the corrective action includes controlling the traction mechanism to stretch the aluminum profile until the maximum horizontal angle between the surface of the aluminum profile and the horizontal plane meets a predetermined corrective threshold.

[0021] Furthermore, the control unit identifies whether the aluminum profile segment is deformed, including:

[0022] The control unit extracts the inner image of the aluminum profile segment contour and compares it with the standard sample image to determine whether there is deformation.

[0023] Furthermore, the control unit calculates the deformation characterization parameter according to formula (1):

[0024]

[0025] In formula (1), D represents the curvature distribution coefficient, n represents the number of segments with deformation, ρi represents the average curvature of the i-th segment, ρ0 represents the preset average curvature threshold, and n0 represents the preset threshold of the number of segments with deformation.

[0026] Further, the control unit adjusts the stretching distance of the traction component according to the deformation characterization parameter, wherein the deformation characterization parameter is positively correlated with the stretching distance of the traction component.

[0027] Further, the control unit adjusts the stretching speed of the traction component according to the deformation characterization parameter, wherein the deformation characterization parameter is negatively correlated with the stretching speed of the traction component.

[0028] Furthermore, the control unit compares the maximum horizontal angle between the aluminum profile surface and the horizontal plane with a preset horizontal angle comparison threshold, and compares the average vertical angle between the corresponding planes at both ends of the aluminum profile and the vertical plane with a preset vertical angle comparison threshold.

[0029] If the maximum horizontal angle between the aluminum profile surface and the horizontal plane is greater than the preset horizontal angle comparison threshold, or the average vertical angle between the corresponding planes at both ends of the aluminum profile and the vertical plane is greater than the preset vertical angle comparison threshold, the control unit determines to control the traction mechanism to perform the corrective action.

[0030] Furthermore, the control unit divides the aluminum profile into a plurality of sections, wherein the length of each section is the same.

[0031] Furthermore, the control unit compares the maximum horizontal angle between the aluminum profile surface and the horizontal plane with a predetermined correction threshold value. If the maximum horizontal angle between the aluminum profile surface and the horizontal plane is less than the predetermined correction threshold value, the control unit determines to stop performing the correction action.

[0032] Compared with the prior art, the present invention uses an extrusion mechanism to perform flame spraying on an aluminum rod and extrude the aluminum rod into an aluminum profile, a detection module obtains an image of the aluminum rod and an image of the aluminum profile, an analysis unit divides the extrusion deformation category according to the surface area ratio of the aluminum profile to the aluminum rod, and a control unit selects an adjustment strategy for the aluminum profile according to the extrusion deformation category, including calculating deformation characterization parameters, adjusting the stretching distance and stretching speed of the traction component, or identifying the maximum horizontal angle between the surface of the aluminum profile and the horizontal plane and the average vertical angle between the corresponding planes at both ends of the aluminum profile and the vertical plane, and judging whether to control the traction mechanism to perform a corrective action. The present invention classifies aluminum profiles according to whether the aluminum profiles are prone to surface shrinkage and bending, and adopts different processing strategies to improve the processing quality of aluminum profiles.

[0033] In particular, the analysis unit of the present invention obtains the surface area ratio of the aluminum profile to the aluminum rod based on the image of the aluminum rod and the image of the aluminum profile, and divides the extrusion deformation category according to the surface area ratio. The aluminum profile is subjected to high temperature and high pressure processing in the extruder, and thus becomes thermoplastic during the extrusion process, causing the crystal structure of the aluminum to change. When the aluminum profile enters the factory environment at normal temperature, the outer layer temperature is relatively low while the interior is still in a high temperature state, resulting in the outer layer being constrained and shrinking, which in turn causes bending. Since the block aluminum profile has a large thickness, the distribution of thermal stress inside and on the surface may be relatively uniform. Therefore, during rapid cooling, there may be less deformation and shrinkage. Compared with the block aluminum profile, the sheet aluminum profile has a larger surface area and a smaller thickness, and is cooled faster, which may cause the surface to be more susceptible to shrinkage and bending. By obtaining the surface area ratio, the shrinkage and bending state of the aluminum profile can be characterized to a certain extent, and different adjustment strategies can be provided for subsequent aluminum profiles. A more appropriate adjustment strategy can be selected to improve the quality of the aluminum profile.

[0034] In particular, the control unit of the present invention adjusts the stretching distance and stretching speed of the traction component according to the deformation characterization parameter. The number of deformed segments in the aluminum profile and the average curvature of the deformed segments are important parameters that characterize the degree of shrinkage and bending of the aluminum profile. When the number of deformed segments in the aluminum profile is large and the average curvature of the deformed segments is large, the degree of shrinkage and bending of the aluminum profile is higher. At this time, the stretching distance should be adjusted to be larger to restore the aluminum profile to a non-shrinkage and bending state. In addition, when stretching an aluminum profile with a large degree of shrinkage and bending, stress concentration may occur in specific parts of the aluminum profile, increasing the risk of material fracture. Therefore, the stretching speed should be slowed down to reduce the possibility of stress concentration, so that the stress is more evenly distributed in the entire structure of the aluminum profile to improve the quality of the aluminum profile.

[0035] In particular, the control unit of the present invention identifies the maximum horizontal angle between the surface of the aluminum profile and the horizontal plane and the average vertical angle between the corresponding planes at both ends of the aluminum profile and the vertical plane, and determines whether to control the traction mechanism to perform corrective action. Since the block aluminum profile has a large thickness, the distribution of thermal stress inside and on the surface may be relatively uniform. Therefore, when it is cooled rapidly, there may be less deformation and shrinkage. In actual conditions, the aluminum profile may have a small degree of bending. Performing corrective action on the aluminum profile by the traction mechanism can improve the quality of the aluminum profile. BRIEF DESCRIPTION OF THE DRAWINGS

[0049] Dividing the aluminum profile into several segments, identifying the number of segments with deformation and the average curvature of the deformed segments, calculating deformation characterization parameters, and adjusting the stretching distance and stretching speed of the traction component according to the deformation characterization parameters;

[0050] Or, identify the maximum horizontal angle between the surface of the aluminum profile and the horizontal plane and the average vertical angle between the corresponding planes at both ends of the aluminum profile and the vertical plane, and determine whether to control the traction mechanism to perform a corrective action, wherein the corrective action includes controlling the traction mechanism to stretch the aluminum profile until the maximum horizontal angle between the surface of the aluminum profile and the horizontal plane meets a predetermined corrective threshold.

[0051] Specifically, the present invention does not limit the specific structure of the extrusion mechanism. The temperature range of the oven is 300°C-500°C. The extruder can extrude the aluminum rod into aluminum profiles of various shapes and specifications. This is the prior art and will not be described in detail.

[0052] Specifically, the present invention does not limit the specific structure of the traction mechanism. The clamp can stably clamp the aluminum profile, and the traction component can move according to a preset motion trajectory. This is the prior art and will not be described in detail.

The images of the aluminum rod and the aluminum profile are acquired by the industrial CCD camera, and the contours of the aluminum rod and the aluminum profile are extracted by image analysis software. The surface area of ​​the aluminum rod and the aluminum profile is calculated. The image analysis software can be ImageJ or MATLAB, which is a prior art and will not be described in detail.

[0054] Specifically, the present invention does not limit the specific structure of the host computer. The analysis unit and the control unit can be composed of logic components or a combination of logic components. The logic components include a field programmable processor, a computer or a microprocessor in a computer. This is a prior art and will not be repeated here.

[0055] Specifically, the analysis unit compares the surface area ratio of the aluminum profile with a preset surface area ratio comparison threshold.

[0056] If the surface area ratio of the aluminum profile is greater than the preset surface area ratio comparison threshold, the analysis unit classifies the extrusion deformation category of the aluminum profile as a strong extrusion deformation category;

[0057] If the surface area ratio of the aluminum profile is less than or equal to the preset surface area ratio comparison threshold, the analysis unit classifies the extrusion deformation category of the aluminum profile as a weak extrusion deformation category.

[0058] In this embodiment, the preset surface area ratio comparison threshold value B0 is obtained in advance through experiments. A number of aluminum bars are extruded into aluminum profiles of various shapes through an extruder, and the shrinkage ratio of the aluminum profile is calculated. When the shrinkage ratio of the aluminum profile is greater than 1%, the ratio of the surface area of ​​the aluminum profile after extrusion to the surface area of ​​the aluminum bar before extrusion is obtained, and the average value is Be. Assume B0=a×Be, a is the surface area coefficient, 0.9<a<1.1.

[0059] Specifically, the analysis unit of the present invention obtains the surface area ratio of the aluminum profile and the aluminum rod based on the image of the aluminum rod and the image of the aluminum profile, and divides the extrusion deformation category according to the surface area ratio. The aluminum profile is subjected to high temperature and high pressure processing in the extruder, and thus becomes thermoplastic during the extrusion process, causing the crystal structure of the aluminum to change. When the aluminum profile enters the factory environment at normal temperature, the outer layer temperature is relatively low while the inner layer is still in a high temperature state, resulting in the outer layer being constrained and shrinking, which in turn causes bending. Since the block aluminum profile has a large thickness, the distribution of thermal stress inside and on the surface may be relatively uniform. Therefore, during rapid cooling, there may be less deformation and shrinkage. Compared with the block aluminum profile, the sheet aluminum profile has a larger surface area and a smaller thickness. It is cooled faster, which may cause the surface to be more prone to shrinkage and bending. By obtaining the surface area ratio, the shrinkage and bending state of the aluminum profile can be characterized to a certain extent, and different adjustment strategies can be provided for subsequent aluminum profiles. A more appropriate adjustment strategy can be selected to improve the quality of the aluminum profile.

[0060] Specifically, the control unit is used to select an adjustment strategy for the aluminum profile according to the type of extrusion deformation of the aluminum profile.

[0061] If the extrusion deformation category of the aluminum profile is a strong extrusion deformation category, the control unit divides the aluminum profile into a plurality of segments, identifies the number of segments with deformation and the average curvature of the deformed segments, calculates deformation characterization parameters, and adjusts the stretching distance and stretching speed of the traction component according to the deformation characterization parameters;

[0062] If the extrusion deformation category of the aluminum profile is a weak extrusion deformation category, the control unit identifies the maximum horizontal angle between the surface of the aluminum profile and the horizontal plane and the average vertical angle between the corresponding planes at both ends of the aluminum profile and the vertical plane, and determines whether to control the traction mechanism to perform a corrective action, wherein the corrective action includes controlling the traction mechanism to stretch the aluminum profile until the maximum horizontal angle between the surface of the aluminum profile and the horizontal plane meets a predetermined corrective threshold.

[0063] Specifically, the control unit identifies whether the aluminum profile segment is deformed, including:

[0064] The control unit extracts the inner image of the aluminum profile segment contour and compares it with the standard sample image to determine whether there is deformation.

[0065] Specifically, there is no specific limitation on the image processing algorithm for determining whether an object is deformed. For example, a feature point detection and matching algorithm can be used to extract feature points in an image and then compare the differences between these feature points and a standard sample image to determine whether the object is deformed. This is a prior art and will not be described in detail.

[0066] Specifically, the control unit calculates the deformation characterization parameter according to formula (1):

[0067]

[0068] In formula (1), D represents the curvature distribution coefficient, n represents the number of segments with deformation, ρi represents the average curvature of the i-th segment, ρ0 represents the preset average curvature threshold, and n0 represents the preset threshold of the number of segments with deformation.

[0069] In this embodiment, the aluminum profile is divided into m segments, n0 is selected in the range of [0.1m, 0.2m], n0 is an integer, ρ0 is obtained in advance from the experiment, and the average curvature of the deformation segment of the aluminum profile with a shrinkage ratio of 1%-2% is obtained in advance. The average value ρa is calculated, and ρ0=b×ρa, b is the curvature coefficient, 0.9<b<1.1.

[0070] Specifically, the control unit adjusts the stretching distance of the traction component according to the deformation characterization parameter, wherein the deformation characterization parameter is positively correlated with the stretching distance of the traction component.

[0071] In this embodiment, optionally,

[0072] 1<D<1.5, the stretching distance of the traction component L1=L0+△L1;

[0073] 1.5≤D<2, the stretching distance of the traction component L2=L0+△L2;

[0074] 2≤D, the stretching distance of the traction component L3=L0+△L3;

[0075] L0 is the initial stretching distance, which is 1% of the length of the aluminum profile, △L1 is the first stretching distance adjustment parameter, △L2 is the second stretching distance adjustment parameter, △L3 is the third stretching distance adjustment parameter, L0<△L1<△L2<△L3<3L0.

[0076] Specifically, the control unit adjusts the stretching speed of the traction component according to the deformation characterization parameter, wherein the deformation characterization parameter is negatively correlated with the stretching speed of the traction component.

[0077] In this embodiment, optionally,

[0078] 1<D<1.5, the stretching speed of the traction component V1=V0-△V1;

[0079] 1.5≤D<2, the stretching speed of the traction component V2=V0-△V2;

[0080] 2≤D, the stretching speed of the traction component V3=V0-△V3;

[0081] V0 is the initial stretching speed, △V1 is the first stretching speed adjustment parameter, △V2 is the second stretching speed adjustment parameter, △V3 is the third stretching speed adjustment parameter, 0.1V0<△V1<△V2<△V3<0.3V0.

[0082] Specifically, the control unit of the present invention adjusts the stretching distance and stretching speed of the traction component according to the deformation characterization parameter. The number of deformed segments in the aluminum profile and the average curvature of the deformed segments are important parameters that characterize the degree of shrinkage and bending of the aluminum profile. When the number of deformed segments in the aluminum profile is large and the average curvature of the deformed segments is large, the degree of shrinkage and bending of the aluminum profile is higher. At this time, the stretching distance should be adjusted to be larger to restore the aluminum profile to a non-shrinkage and bending state. In addition, when stretching an aluminum profile with a large degree of shrinkage and bending, stress concentration may occur in specific parts of the aluminum profile, increasing the risk of material fracture. Therefore, the stretching speed should be slowed down to reduce the possibility of stress concentration, so that the stress is more evenly distributed in the entire structure of the aluminum profile to improve the quality of the aluminum profile.

[0083] Specifically, the control unit compares the maximum horizontal angle between the aluminum profile surface and the horizontal plane with a preset horizontal angle comparison threshold, and compares the average vertical angle between the corresponding planes at both ends of the aluminum profile and the vertical plane with a preset vertical angle comparison threshold.

[0084] If the maximum horizontal angle between the aluminum profile surface and the horizontal plane is greater than the preset horizontal angle comparison threshold, or the average vertical angle between the corresponding planes at both ends of the aluminum profile and the vertical plane is greater than the preset vertical angle comparison threshold, the control unit determines to control the traction mechanism to perform the corrective action.

[0085] In this embodiment, the preset horizontal angle comparison threshold is selected within the range of [3°, 5°], and the preset vertical angle comparison threshold is selected within the range of [1°, 3°].

[0086] Specifically, the control unit divides the aluminum profile into a plurality of segments, wherein the length of each segment is the same.

[0087] Specifically, the control unit compares the maximum horizontal angle between the aluminum profile surface and the horizontal plane with a predetermined correction threshold. If the maximum horizontal angle between the aluminum profile surface and the horizontal plane is less than the predetermined correction threshold, the control unit determines to stop performing the correction action.

[0088] In this embodiment, the predetermined correction threshold is selected within the range of [1°, 2°].

[0089] Specifically, in this embodiment, the corrective action is that the control unit controls the traction component to move a preset distance in the direction of a preset trajectory every preset time, the preset time is selected within the range of [20s, 30s], the preset trajectory direction is the direction of horizontally stretching the aluminum profile, and the preset distance is selected within the range of [2cm, 5cm].

[0090] Specifically, the control unit of the present invention identifies the maximum horizontal angle between the surface of the aluminum profile and the horizontal plane and the average vertical angle between the corresponding planes at both ends of the aluminum profile and the vertical plane, and determines whether to control the traction mechanism to perform corrective action. Since the block aluminum profile has a large thickness, the distribution of thermal stress inside and on the surface may be relatively uniform. Therefore, there may be less deformation and shrinkage during rapid cooling. In actual conditions, the aluminum profile may be slightly bent. Performing corrective action on the aluminum profile through the traction mechanism can improve the quality of the aluminum profile.

[0091] So far, the technical solutions of the present invention have been described in conjunction with the preferred embodiments shown in the accompanying drawings. However, it is easy for those skilled in the art to understand that the protection scope of the present invention is obviously not limited to these specific embodiments. Without departing from the principle of the present invention, those skilled in the art can make equivalent changes or substitutions to the relevant technical features, and the technical solutions after these changes or substitutions will fall within the protection scope of the present invention.
