[0044] In order to solve the technical problem of low installation efficiency of existing hyperbolic suspended ceiling, the present application provides a hyperbolic suspended ceiling method based on a modular unit, which can be executed by software and / or hardware device. For example, please refer to Figure 1 , Figure 1 A flowchart of a hyperbolic suspended ceiling method based on a modular unit provided by the embodiments of the present application is shown, which includes the following steps:

[0045] S101, obtain a three-dimensional model of a hyperbolic suspended ceiling, and split the three-dimensional model of the hyperbolic suspended ceiling into a plurality of standardized hyperbolic modular units. Specifically, in the embodiments of the present application, a three-dimensional modeling software and a parameterization algorithm are used to generate a three-dimensional model of a hyperbolic suspended ceiling, and the three-dimensional model of the hyperbolic suspended ceiling is split into a plurality of standardized hyperbolic modular units. The shapes and areas of the plurality of standardized hyperbolic modular units are similar, and can be formed by the same mold stamping, the different hyperbolic modular units can be changed by a gap, the unit contour can be controlled, and different sizes of hyperbolic modular units can be made by the same mold.

[0046] S102, extract the profile curve data of each hyperbolic module unit, and plan the machining path of the tool based on the profile curve data of each hyperbolic module unit. Specifically, in the embodiment of the application, after the three-dimensional model of the hyperbolic ceiling is divided into a plurality of standardized hyperbolic module units, the edge profile curve of each unit can be extracted through the operator component in the parametric modeling software, then the tool path is planned based on the extracted profile curve data of each hyperbolic module unit, and the surface engraving path is generated through the numerical control machine tool. Finally, the process is layered, the lower knife point is set through the operator component to avoid the lower knife at the sharp corner, and the cutting depth gradient is controlled, for example, 3mm plate is processed in 2 layers.

[0047] S103, adjust the curvature of the stamping die according to the three-dimensional model of the hyperbolic module unit, and stamp the aluminum material through the stamping die after adjusting the curvature to make a plurality of splicable hyperbolic aluminum plates. Specifically, in the embodiment of the application, by adjusting the curvature of the stamping die, the aluminum plate can accurately meet the requirements of the hyperbolic module unit design, ensuring that the shape and structure of the finished product meet the design standards, avoiding errors in the manufacturing process, and the die after adjusting the curvature can batch produce hyperbolic aluminum plates with consistent shape, effectively improving the production efficiency of the hyperbolic aluminum plate, reducing manual intervention and errors, and making the splicable hyperbolic aluminum plate, making the subsequent process of splicing into a hyperbolic ceiling more convenient.

[0048] S104, cut each hyperbolic aluminum plate according to the planned tool machining path, and weld each cut hyperbolic aluminum plate into a cavity structure. Specifically, in the embodiment of the application, the planning of the tool machining path enables each aluminum plate to be cut according to accurate size and shape, reducing cutting errors. By welding the cut aluminum plate into a cavity structure, the stability and carrying capacity of the overall structure of the hyperbolic aluminum plate can be effectively improved.

[0049] S105, fix each hyperbolic aluminum plate welded into a cavity structure through a keel assembly, and splice the fixed hyperbolic aluminum plates to form a spliced hyperbolic ceiling. Specifically, in the embodiment of the application, the keel assembly provides reliable support and fixation for the hyperbolic aluminum plate, ensuring accurate docking and structural stability between each hyperbolic aluminum plate, and avoiding loosening or deformation of the hyperbolic ceiling.

[0050] As an embodiment, please refer to Figure 2 , Figure 2 A flowchart of a method for segmenting standardized hyperbolic module units is provided in the embodiment of the application, S101, a three-dimensional model of a hyperbolic ceiling is obtained, and the three-dimensional model of the hyperbolic ceiling is divided into a plurality of standardized hyperbolic module units, specifically including:

[0051] S1011, construct a three-dimensional model of the hyperbolic ceiling according to the architectural drawing, and locally fine-tune the surface control points of the constructed three-dimensional model of the hyperbolic ceiling. Specifically, in the embodiment of the present application, first, an initial hyperbolic ceiling model can be created according to the architectural drawing and the architectural scheme model, and then the hyperbolic ceiling model can be optimized, the surface control points in the high-curvature area can be locally fine-tuned, and the overall curvature is ensured to be smooth. Through the fine-tuning of the surface control points, the present application can accurately control the shape of the ceiling surface, ensure that it is completely consistent with the architectural design requirements, and avoid errors in the construction process.

[0052] S1012, preset the segmentation number of the three-dimensional model of the locally fine-tuned hyperbolic ceiling, and divide the three-dimensional model of the hyperbolic ceiling into a plurality of standardized surface blocks according to the preset segmentation number. Specifically, in the embodiment of the present application, according to the size limitation of the production equipment and the requirement of the facade effect, the segmentation number of the three-dimensional model of the locally fine-tuned hyperbolic ceiling is preset first, the UV interval is divided according to the preset modulus size through the mathematical component in the parametric modeling software, the surface of the hyperbolic ceiling is divided into uniform UV surface, and the division size of the optimal surface block is obtained. The present application divides the complex surface into a plurality of standardized blocks, so that the manufacturing and installation of each block are more convenient, and through the preset segmentation number of the three-dimensional model of the locally fine-tuned hyperbolic ceiling, the size and shape of each surface block can be ensured to be consistent, which is helpful for subsequent processing and splicing, and avoids the mismatching problem caused by large size deviation.

[0053] S1013, extract the segmentation line of each surface block in the three-dimensional model of the hyperbolic ceiling, and offset the segmentation line of each surface block to obtain the joint between each surface block in the three-dimensional model of the hyperbolic ceiling. Specifically, in the embodiment of the present application, the program in the parametric modeling software is used to extract the surface structure line, and the structure line is used as the block grid line; the program in the parametric modeling software is used to offset the grid line to obtain the joint between the surface blocks. Through the preset segmentation number, the present application can ensure that the size and shape of each surface block are consistent or similar, and avoid the mismatching problem caused by size deviation. The joint design formed after the offset processing can effectively reduce the misconnection problem caused by installation errors, and ensure the smooth progress of the splicing process.

[0054] S1014, based on the joint between each surface block in the three-dimensional model of the hyperbolic ceiling, divide each surface block into a plurality of standardized hyperbolic modulus units. Specifically, in the embodiment of the present application, the area of the divided hyperbolic modulus unit can be calculated first, then the boundary coordinates of the hyperbolic modulus unit are extracted, and then the types of the surface blocks are counted to select the optimal standard hyperbolic block. The present application divides the entire hyperbolic ceiling into standardized units, each unit can use the same manufacturing process and technology, which reduces material waste, simplifies production steps, and thus reduces manufacturing cost.

[0055] As an implementation form, based on the seams between the curved surface panels in the three-dimensional model of the hyperbolic suspended ceiling, the curved surface panels are divided into a plurality of standardized hyperbolic modular units, and then the method further comprises: presetting a gap error threshold of each standardized hyperbolic modular unit, and calculating a gap error value of each standardized hyperbolic modular unit; if the calculated gap error value of each standardized hyperbolic modular unit is greater than or equal to the preset gap error threshold, the three-dimensional model of the hyperbolic suspended ceiling is re-divided to obtain a standardized hyperbolic modular unit with a gap error value less than the preset gap error threshold. Specifically, in the embodiment of the present application, after the curved surface panels are divided into a plurality of standardized hyperbolic modular units, the gap error values between the four edges of each non-standardized hyperbolic modular unit and the standardized hyperbolic modular unit can be calculated, and if the calculated gap error value of each standardized hyperbolic modular unit is greater than or equal to the preset gap error threshold, the three-dimensional model of the hyperbolic suspended ceiling is re-divided, for example, the preset gap error threshold is 5mm, if there is an error value exceeding 5mm, the three-dimensional model of the hyperbolic suspended ceiling is re-divided until a standardized hyperbolic modular unit with a gap error value less than the preset gap error threshold is obtained. By presetting the gap error threshold and calculating the error, the present application ensures that the gap error of each hyperbolic unit does not exceed the preset range, thereby ensuring the assembly quality of the hyperbolic suspended ceiling.

[0056] As an implementation form, S105, the curved aluminum plates welded into a cavity structure are fixed by the keel assembly, and the fixed curved aluminum plates are spliced to form a spliced hyperbolic suspended ceiling, specifically comprising:

[0057] S1051, the curved aluminum plates welded into a cavity structure are fixed into aluminum plate units by the connecting piece, and each aluminum plate unit is fixed on the aluminum keel frame by the fixing piece. Specifically, in the embodiment of the present application, the blocking side plate can be completely welded and fixed with the hyperbolic aluminum plate as an aluminum plate unit, and the aluminum plate unit is fixed on the aluminum keel frame by the fixing piece, so that each aluminum plate unit is not easy to produce deviation or looseness after installation.

[0058] S1052, the plug-in base is arranged on each aluminum keel frame, and the aluminum plate units are spliced by the plug-in base to form a spliced hyperbolic suspended ceiling. Specifically, in the embodiment of the present application, at least two plug-in bases can be arranged on each aluminum keel frame, and the aluminum plate units are installed in close contact by the plug-in base, and finally, a spliced hyperbolic suspended ceiling is formed.

[0059] As an implementation form, after the three-dimensional model of the hyperbolic suspended ceiling is split into a plurality of standardized hyperbolic module units, and before the profile curve data of each hyperbolic module unit is extracted, the method further comprises: configuring geometric constraints according to the size of each hyperbolic module unit in the three-dimensional model of the hyperbolic suspended ceiling, and configuring a cutting tool according to the material of the hyperbolic suspended ceiling. Specifically, in the embodiment of the present application, geometric constraints of the maximum machining size, the minimum detail size, the minimum curvature radius and the clippable size of each hyperbolic module unit can be set first, which can ensure that the shape, size and relative position of each unit strictly meet the design requirements. Secondly, the cutting tool is configured according to the material of the hyperbolic suspended ceiling, for example, if the hyperbolic suspended ceiling is an aluminum single plate, a double-edge spiral milling cutter can be selected, the rotating speed can be configured as 12000 rpm, and the feed can be configured as 2 m / min. By configuring the geometric constraints and the cutting tool of the hyperbolic module unit in advance, the present application can realize higher degree of automation in the production process, and the size of each hyperbolic module unit and the configuration of the cutting tool can be transmitted to the numerical control machine tool or the automatic production equipment in a digital manner, greatly reducing manual intervention.

[0060] As an implementation form, the geometric constraints are configured according to the size of each hyperbolic module unit in the three-dimensional model of the hyperbolic suspended ceiling, and the cutting tool is configured according to the material of the hyperbolic suspended ceiling, comprising:

[0061] The maximum machining size of each hyperbolic module unit in the three-dimensional model of the hyperbolic suspended ceiling is configured to be less than or equal to the size of the table surface of the numerical control machine tool. Specifically, in the embodiment of the present application, the numerical control machine tool has a fixed table surface size, and it cannot be machined beyond the range, therefore, the maximum machining size of each hyperbolic module unit can be configured to be less than or equal to the size of the table surface of the numerical control machine tool, for example, if the numerical control machine tool is 1200x2400mm, the maximum machining size of each hyperbolic module unit is configured to be less than or equal to 1200x2400mm.

[0062] The minimum detail size of each hyperbolic module unit in the three-dimensional model of the hyperbolic suspended ceiling is configured to be greater than or equal to the size of the tool diameter. Specifically, in the embodiment of the present application, the tool diameter limits its minimum machining capability. If the detail is smaller than the tool diameter, it may not be machined at all, or it may be cut by mistake. Therefore, the minimum detail size of each hyperbolic module unit can be configured to be greater than or equal to the size of the tool diameter, for example, if the tool diameter is 6mm, the maximum machining size of each hyperbolic module unit is configured to be less than or equal to 6.5nm.

[0063] The minimum curvature radius size of each hyperbolic modulus unit in the three-dimensional model of the hyperbolic suspended ceiling is configured to be greater than or equal to the size of the tool radius. Specifically, in the embodiment of the present application, if the curvature radius is less than the tool radius, the tool cannot accurately fit the curved surface, which will cause cutting to be out of place or interference and collision. Therefore, the minimum curvature radius size of each hyperbolic modulus unit can be configured to be greater than or equal to the size of the tool radius, for example, the tool diameter is 6mm, and the minimum curvature radius size of each hyperbolic modulus unit is configured to be greater than or equal to 3nm.
