Multi-curved special-shaped aluminum veneer deformation control construction process

Abstract

This invention discloses a construction process for controlling the deformation of multi-curved irregular-shaped aluminum panels. The first pre-assembly ensures the aluminum panel processing accuracy meets requirements; the second pre-assembly controls the deformation and angular deviation of the assembled aluminum panel units; and the third pre-assembly ensures the qualified connection between multiple aluminum panel units. These three pre-assembly processes ensure the processing accuracy of the aluminum panels and guarantee a high rate of qualified aluminum panels leaving the factory. A shaping plate serves as a benchmark for controlling interface dimensions, allowing for timely detection of deformation in aluminum panel units. The shaping plate also reduces deformation during subsequent processes. During the spraying process, when the aluminum panel is suspended on one side, it will not deform due to its own weight. Under spraying and baking conditions, the deformation of the aluminum panel is also greatly reduced. Through the combined effect of the three pre-assembly processes and the shaping plate, the final finished aluminum panel can achieve the preset shape.

Description

Technical Field

[0001] This invention relates to the field of aluminum panel processing technology, specifically to a construction process for controlling the deformation of multi-curved irregular-shaped aluminum panels. Background Technology

[0002] Building curtain walls are a common form of exterior wall design in existing buildings. Aluminum panels, as a curtain wall material with low cost, light weight, and good corrosion resistance, are increasingly used in various types of buildings. The application of aluminum panels in buildings with relatively standard exterior wall shapes is a very mature technology. However, in irregularly shaped curtain walls, due to their relatively low cost, more and more projects are using them. But, because aluminum panels themselves are in multi-curved shapes, multiple deformations such as surface processing deviations, welding deformation, high-temperature spraying deformation, and deformation due to their own weight or stacking during transportation can lead to a high rate of defective products, often making it difficult to achieve the desired design effect. Summary of the Invention

[0003] Therefore, the technical problem to be solved by the present invention is that the processing of multi-curved irregular aluminum panels in the prior art is prone to deformation and the final product is difficult to achieve the preset shape effect, so as to provide a construction process for controlling the deformation of multi-curved irregular aluminum panels.

[0004] To solve the above-mentioned technical problems, the technical solution of the present invention is as follows:

[0005] A construction process for controlling deformation of multi-curved irregular-shaped aluminum panels includes the following steps:

[0006] S1: Produce multiple wooden molds with corresponding shapes based on the designed aluminum plate model drawing;

[0007] S2: The aluminum plates are bent one by one using the multiple wooden molds mentioned in step S1;

[0008] S3: Perform the first pre-assembly of each aluminum plate after bending in step S2;

[0009] S4: Assemble and weld the multiple aluminum plates that passed the first pre-assembly in step S3 into an aluminum plate unit;

[0010] S5: Perform a second pre-assembly of the aluminum plate units that have been assembled and welded in step S4;

[0011] S6: A shaping plate is set on the cross-section of the aluminum plate unit that has passed the second pre-assembly in step S5;

[0012] S7: Angle brackets and back ribs are provided on the aluminum plate unit with the shaping plate set in step S6;

[0013] S8: Perform a third pre-assembly of the polished aluminum plate unit from step S7.

[0014] S9: Polish, pickle, and spray the aluminum plate units that have passed the third pre-assembly in step S8, and then inspect and accept them.

[0015] Furthermore, in step S1, the aluminum plate model needs to be disassembled piece by piece according to the designed aluminum plate splicing shape, and then based on the disassembled model... Figure 1 One is to produce wooden molds with corresponding shapes and curvatures.

[0016] Furthermore, in step S3, if misalignment or inaccurate splicing is found between adjacent aluminum plates in the first pre-assembly, it indicates that the bending of an aluminum plate is unsuccessful and needs to be repeated according to step S2 until the first pre-assembly is qualified.

[0017] Furthermore, in step S4, after all the aluminum plates have passed the first pre-assembly, all the aluminum plates are assembled into aluminum plate units, and spot welding is used to fix the individual aluminum plates together.

[0018] Furthermore, in step S5, the assembled aluminum plate unit is pre-assembled a second time to confirm whether the splicing angle between individual aluminum plates on the aluminum plate unit is qualified. If it is not qualified, the assembly and spot welding are repeated according to step S4 until the second pre-assembly is qualified.

[0019] Furthermore, in step S6, the shaping plate is welded to both ends and the middle of the aluminum plate unit after the second pre-assembly is qualified.

[0020] Furthermore, in step S6, after the welding and installation of the shaping plate is completed, the joint between two adjacent aluminum plates on the aluminum plate unit is fully welded and fixed, and then the weld is ground.

[0021] Furthermore, multiple aluminum plate units are provided, and the multiple aluminum plate units are bolted together by a keel frame.

[0022] Furthermore, the shaping plate is provided with keel holes suitable for inserting the keel frame.

[0023] Furthermore, in step S8, multiple aluminum plate units bolted together by a keel frame are pre-assembled for the third time.

[0024] The technical solution of this invention has the following advantages:

[0025] 1. The deformation control construction process for multi-curved irregular aluminum panels provided by this invention ensures that the aluminum panel processing accuracy meets requirements through a first pre-assembly process. A second pre-assembly process controls the deformation and angular deviation of the assembled aluminum panel units. A third pre-assembly process ensures the qualified connection between multiple aluminum panel units. These three additional pre-assembly processes ensure the processing accuracy of the aluminum panel at each step, guaranteeing a high factory pass rate. By setting a shaping plate, it can serve as a benchmark for controlling interface dimensions, allowing for timely detection of deformation in aluminum panel units. Furthermore, the fixing effect of the shaping plate reduces deformation during subsequent processes. During the spraying process, when the aluminum panel is suspended on one side, it will not deform due to its own weight. Under spraying and baking conditions, the deformation of the aluminum panel is also greatly reduced. Through the combined effect of the three pre-assembly processes and the shaping plate, the final finished aluminum panel can achieve the preset shape effect.

[0026] 2. In the multi-curved irregular aluminum single panel deformation control construction process provided by the present invention, in step S1, the aluminum panel model needs to be disassembled one by one according to the designed aluminum panel splicing shape, and then according to the disassembled model... Figure 1 A wooden mold with the corresponding shape and curvature is produced. This setup allows the aluminum sheet to be broken down into the required shape and processed one by one, simplifying the processing and improving efficiency.

[0027] 3. The deformation control construction process for multi-curved irregular aluminum panels provided by this invention, in step S3, if misalignment or inability to accurately splice adjacent aluminum panels during the first pre-assembly is found, it indicates that the bending of an aluminum panel has failed, and it needs to be bent again according to step S2 until the first pre-assembly is qualified. This setting can ensure the bending accuracy of the aluminum panel, ensure that the cross-section of the aluminum panel is consistent with the design dimensions, improve the subsequent aluminum panel splicing accuracy, and reduce the amount of rework.

[0028] 4. The deformation control construction process for multi-curved irregular aluminum panels provided by this invention, in step S4, after all aluminum panels have passed the first pre-assembly, all aluminum panels are assembled into aluminum panel units, and spot welding is used to fix the individual aluminum panels together. This setup, using spot welding to initially connect and fix the aluminum panel units, compared to the existing technology which uses full welding directly after assembly, facilitates control and adjustment after angular deviations occur in the assembled aluminum panel units, ensuring the shape accuracy of the aluminum panel units and reducing subsequent rework.

[0029] 5. The deformation control construction process for multi-curved irregular aluminum single panels provided by this invention includes a second pre-assembly of the assembled aluminum panel unit in step S5 to confirm whether the splicing angle between individual aluminum panels on the unit is qualified. If not, the assembly and spot welding are repeated according to step S4 until the second pre-assembly is qualified. This setup ensures the accuracy of the bending degree of the aluminum panel unit and ensures that the cross-sectional shape of the aluminum panel unit is consistent with the design shape, thereby ensuring that the final product is consistent with the preset shape.

[0030] 6. The deformation control construction process for multi-curved irregular aluminum panels provided by this invention includes, in step S6, welding shaping plates to both ends and the middle of the aluminum panel unit after the second pre-assembly is qualified. This arrangement ensures that the dimensions of the aluminum panel unit are consistent with the design requirements and that the end cross-sectional dimensions of each aluminum panel unit are consistent. Therefore, after the aluminum panel unit is hoisted, there will be no misalignment of the aluminum panel lines due to inconsistent cross-sectional dimensions between adjacent aluminum panel units.

[0031] 7. The deformation control construction process for multi-curved irregular aluminum panels provided by this invention, in step S6, after the welding and installation of the shaping plate is completed, the joint between two adjacent aluminum plates on the aluminum plate unit is fully welded and fixed, and then the weld is ground. This arrangement, performing full welding and fixing after assembly and shaping plate installation, ensures that the aluminum plate will not deform due to high temperatures during welding.

[0032] 8. The deformation control construction process for multi-curved irregular aluminum panels provided by this invention includes a third pre-assembly in step S8, where multiple aluminum panel units bolted together by a keel frame are assembled. This arrangement ensures the consistency between the finished aluminum panel assembled from multiple aluminum panel units and the preset shape, guaranteeing that the finished aluminum panel achieves the preset shape effect.

[0037] The technical solution of the present invention will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0040] Furthermore, the technical features involved in the different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0041] like Figure 1 The deformation control construction process for multi-curved irregular aluminum panels shown includes the following steps:

[0042] S1: Produce multiple wooden molds with corresponding shapes based on the designed aluminum plate model drawing;

[0043] S2: The aluminum plates are bent one by one using the multiple wooden molds mentioned in step S1;

[0044] S3: Perform the first pre-assembly of each aluminum plate after bending in step S2;

[0045] S4: Assemble and weld the multiple aluminum plates that passed the first pre-assembly in step S3 into an aluminum plate unit;

[0046] S5: Perform a second pre-assembly of the aluminum plate units that have been assembled and welded in step S4;

[0047] S6: A shaping plate is set on the cross-section of the aluminum plate unit that has passed the second pre-assembly in step S5;

[0048] S7: Angle brackets and back ribs are provided on the aluminum plate unit with the shaping plate set in step S6;

[0049] S8: Perform a third pre-assembly of the polished aluminum plate unit from step S7.

[0050] S9: Polish, pickle, and spray the aluminum plate units that have passed the third pre-assembly in step S8, and then inspect and accept them.

[0051] This multi-curved, irregularly shaped aluminum panel deformation control construction process uses three steps: a first pre-assembly to ensure the aluminum panel processing accuracy meets requirements; a second pre-assembly to control the deformation and angular deviation of the assembled aluminum panel units; and a third pre-assembly to ensure the connection between multiple aluminum panel units is qualified. These three additional pre-assembly steps ensure the processing accuracy of the aluminum panel at each step, guaranteeing a high rate of qualified aluminum panels leaving the factory. By setting up a shaping plate 1, it can serve as a benchmark for controlling interface dimensions, allowing for timely detection of deformation in aluminum panel units. Simultaneously, the fixing effect of the shaping plate 1 reduces deformation during subsequent processes. During the spraying process, when the aluminum panel is suspended on one side, it will not deform due to its own weight. Under spraying and baking conditions, the deformation of the aluminum panel is also greatly reduced. Through the combined effect of the three pre-assembly steps and the shaping plate 1, the final finished aluminum panel can achieve the preset shape effect.

[0052] In step S1, the model drawing of the aluminum plate must first be verified. Then, according to the designed splicing shape of the aluminum plate, it needs to be disassembled one by one to process the aluminum plate in batches. Finally, based on the disassembled model... Figure 1 A wooden mold with the corresponding shape and curvature is produced. This setup allows the aluminum sheet to be broken down into the required shape and processed one by one, simplifying the processing and improving efficiency.

[0053] After completing step S1, the aluminum plate raw material is fed and unloaded, followed by step S2.

[0054] In step S3, if misalignment or inaccurate splicing is found between adjacent aluminum plates in the first pre-assembly, it indicates that the bending of an aluminum plate was unsuccessful, and it needs to be bent again according to step S2 until the first pre-assembly is qualified. This setting can ensure the bending accuracy of the aluminum plates, ensure that the cross-section of the aluminum plates is consistent with the design dimensions, improve the subsequent aluminum plate splicing accuracy, and reduce the amount of rework.

[0055] In step S4, after all aluminum plates pass the initial pre-assembly, they are assembled into aluminum plate units, and spot-welded to fix the individual aluminum plates together. This setup, using spot welding for initial connection and fixation of the aluminum plate units, is more efficient than the existing technology that uses full welding after assembly. Spot welding allows for easier control and adjustment if angular deviations occur in the assembled aluminum plate units, ensuring the shape accuracy of the units and reducing subsequent rework.

[0056] In step S5, the assembled aluminum plate units undergo a second pre-assembly to confirm whether the splicing angle between individual aluminum plates on the unit is acceptable. If not, the assembly and spot welding are repeated according to step S4 until the second pre-assembly is successful. This setup ensures the accuracy of the bending of the aluminum plate units and guarantees that the cross-sectional shape of the aluminum plate units matches the design shape, thus ensuring that the final product matches the preset shape.

[0057] In step S6, shaping plates 1 are welded to both ends and the middle of the aluminum plate unit after the second pre-assembly is qualified. This setting ensures that the size of the aluminum plate unit is consistent with the design requirements, and also ensures that the end cross-sectional dimensions of each aluminum plate unit are consistent. After the aluminum plate unit is hoisted, there will be no misalignment of the aluminum plate lines due to inconsistent cross-sectional dimensions between adjacent aluminum plate units.

[0058] In step S6, after the welding and installation of the shaping plate 1 are completed, the joint between two adjacent aluminum plates on the aluminum plate unit is fully welded and fixed, and then the weld is ground. This setting, which involves fully welding and fixing after the assembly and installation of the shaping plate 1, ensures that the aluminum plates will not deform due to high temperatures during welding.

[0059] In this embodiment, multiple aluminum plate units are provided, and these units are bolted together by a keel frame. Specifically, the shaping plate 1 has keel holes 2 suitable for the keel frame to pass through. In step S8, the multiple aluminum plate units bolted together by the keel frame are pre-assembled for the third time. This arrangement ensures that the finished aluminum plate assembled from multiple aluminum plate units conforms to the preset shape, guaranteeing that the finished aluminum plate achieves the preset shape effect.

[0060] In summary, this multi-curved irregular aluminum panel deformation control construction process ensures the aluminum panel processing accuracy meets requirements through the first pre-assembly. The second pre-assembly process controls the deformation and angular deviation of the assembled aluminum panel units. The third pre-assembly process ensures the qualified connection between multiple aluminum panel units. These three additional pre-assembly processes ensure the processing accuracy of the aluminum panel at each step, guaranteeing the factory pass rate. By setting up the shaping plate 1, it can serve as a benchmark for controlling the interface dimensions, allowing for timely detection of deformation in aluminum panel units. Furthermore, the fixing effect of the shaping plate 1 reduces deformation during subsequent processes. During the spraying process, when the aluminum panel is suspended on one side, it will not deform due to its own weight. Under spraying and baking conditions, the deformation of the aluminum panel is also greatly reduced. Through the combined effect of the three pre-assembly processes and the shaping plate 1, the final finished aluminum panel can achieve the preset shape effect.

[0061] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the scope of protection of this invention.
