Description

Technical Field

[0001] This invention relates to the field of bulk material conveying technology, and in particular to a method and apparatus for manufacturing a torsion-connected chute. Background Technology

[0002] In existing technologies, bulk material conveying often relies on multiple conveyors, and connecting chutes are transfer devices used to connect adjacent conveyors. The transfer method between two conveyors can be categorized based on the angle between them, such as parallel transfer, perpendicular transfer, obtuse-angle transfer, and acute-angle transfer. When the transfer method is perpendicular or parallel, since the cross-sectional shape and direction of the upstream conveyor's outlet and the downstream conveyor's inlet are consistent, the outlet cross-section of the connecting chute between adjacent upstream and downstream conveyors only needs to be aligned with the inlet cross-section direction. In this case, the fabrication and installation of the connecting chute are relatively convenient.

[0003] However, when the transfer is at an obtuse or acute angle, in order to ensure that the bulk material is transferred to the downstream conveyor in the correct orientation and to ensure that the shape and direction of the chute opening do not conflict with the pipe inlet of the downstream conveyor and the pipe outlet of the upstream conveyor, it is often necessary to rebuild a pipe inlet on the downstream conveyor with a shape and direction corresponding to the chute outlet section, and rebuild a pipe outlet on the upstream conveyor with a shape and direction corresponding to the chute inlet section. Alternatively, a large amount of manpower and resources may be spent readjusting the angle between adjacent conveyors. As a result, the installation of the connecting chute requires a lot of time and cost, is difficult to install, and has low installation efficiency.

[0004] While existing technologies include methods for designing chutes in a "square-to-round + round-to-square" configuration—where the inlet section is square-to-round to match the shape and orientation of the upstream conveyor's outlet section, and the outlet section is round-to-square to match the shape and orientation of the downstream conveyor's inlet section—and the inlet and outlet sections are connected by an intermediate circular pipe for transition, this method results in a complex chute structure, high manufacturing difficulty, and high raw material consumption, leading to high production costs and consequently low efficiency in manufacturing connecting chutes.

[0005] In summary, the existing methods for manufacturing connecting pipes are difficult and costly, resulting in low efficiency in manufacturing connecting pipes and high difficulty in installing connecting pipes, which in turn leads to low installation efficiency. Summary of the Invention

[0006] One object of the present invention is to provide a method for manufacturing a torsion connecting duct, thereby solving the problems of high difficulty and cost in manufacturing connecting ducts in the prior art, resulting in low efficiency in manufacturing connecting ducts and high difficulty in installing connecting ducts, thus leading to low installation efficiency. Another object of the present invention is to provide an apparatus for manufacturing a torsion connecting duct. A further object of the present invention is to provide a computer device. A still other object of the present invention is to provide a readable medium.

[0007] To achieve the above objectives, one aspect of the present invention discloses a method for manufacturing a torsion-connected chute, the method comprising:

[0011] Optional, further including:

[0012] Before connecting each vertex of the preset first chute inlet cross-section model to the two nearest vertices of the preset second chute inlet cross-section model to obtain the torsional connection chute frame model.

[0013] Based on the outlet of the upstream conveyor of the target, multiple vertices of the chute inlet section are determined, and the first chute inlet section model is formed based on the multiple vertices of the chute inlet section.

[0014] Based on the inlet of the target downstream conveyor, multiple vertices of the chute outlet section are determined, and a second chute outlet section model is formed based on the multiple vertices of the chute outlet section.

[0015] Optionally, the step of forming the first chute inlet cross-section model based on multiple vertices of the chute inlet cross-section includes:

[0016] A three-dimensional coordinate system is constructed with the center of the chute inlet section as the origin.

[0017] The first chute inlet cross-section model is constructed based on the coordinates of multiple vertices of the chute inlet cross-section in a three-dimensional coordinate system;

[0018] Correspondingly, the formation of the second chute outlet cross-section model based on multiple vertices of the chute outlet cross-section includes:

[0020] Optionally, the step of connecting each vertex of the preset first chute inlet cross-section model to the two closest vertices in the preset second chute inlet cross-section model to obtain a torsion-connected chute frame model includes:

[0021] Select a first starting vertex from the vertices of the first chute inlet cross-section model, and determine the vertex of the second chute inlet cross-section model that is closest to the first starting vertex as the second starting vertex;

[0022] Using the first starting vertex as the first selected vertex and the second starting vertex as the second selected vertex, a misaligned connection operation is performed. The misaligned connection operation includes:

[0023] Based on the first selected vertex, determine the first target vertex in the first chute cross-section model that is adjacent to the first target vertex in the preset target direction, connect the second selected vertex and the first target vertex, and based on the second selected vertex, determine the second target vertex in the second chute cross-section model that is adjacent to the second target vertex in the target direction, connect the second target vertex and the first target vertex.

[0024] Using the first target vertex as the first selected vertex and the second target vertex as the second selected vertex, the misaligned connection operation is repeated until the first starting vertex is connected to the second starting vertex, thus obtaining the torsion connection chute frame model.

[0025] Optionally, selecting the first starting vertex from the vertices of the first chute orifice cross-section model includes:

[0026] The center of the second chute inlet cross-section model is taken as the starting reference point;

[0027] The vertex furthest from the starting reference point among the vertices of the first chute inlet cross-section model is determined as the first starting vertex.

[0028] Optionally, filling the torsion-connected chute frame model to obtain the torsion-connected chute peripheral substrate model includes:

[0029] The boundary is filled with the connecting lines formed by the edges and all vertices of the first and second chute cross-section models to obtain the outer substrate model of the torsion connection chute.

[0030] Optionally, the step of encapsulating the outer substrate model of the torsion-connected chute to obtain the final model of the torsion-connected chute includes:

[0031] Each substrate in the outer substrate model of the torsion connection chute is thickened to obtain the first intermediate model;

[0032] A flange model corresponding to the first chute inlet cross-section model is constructed at the first intermediate model to obtain the second intermediate model;

[0033] A liner model corresponding to the inner surface of each substrate in the second intermediate model is constructed to obtain the final model of the torsion connection chute.

[0034] Optionally, the step of constructing a liner model corresponding to the inner surface of each substrate in the second intermediate model to obtain the final model of the torsion connection chute includes:

[0035] A liner model of a predetermined thickness is formed using the inner surface of each substrate as a reference surface; wherein the size of the liner model is smaller than the size of the corresponding substrate.

[0036] To achieve the above objectives, another aspect of the present invention discloses a torsion connection chute manufacturing apparatus, comprising:

[0037] The torsion connection chute frame model construction module is used to connect each vertex of the preset first chute inlet cross-section model to the two closest vertices in the preset second chute inlet cross-section model to obtain the torsion connection chute frame model.

[0038] A module for constructing a model of the outer substrate of a torsion-connected chute is used to fill the frame model of the torsion-connected chute to obtain a model of the outer substrate of the torsion-connected chute.

[0039] The final model construction module for the torsion connection chute is used to encapsulate the peripheral substrate model of the torsion connection chute to obtain the final model of the torsion connection chute, so as to manufacture the torsion connection chute based on the final model of the torsion connection chute.

[0042] The present invention provides a method and apparatus for manufacturing a torsion-connected chute. By connecting each vertex of a preset first chute inlet cross-section model to the two closest vertices of a preset second chute inlet cross-section model, a torsion-connected chute frame model is obtained. This ensures that the edges connecting the vertices in the frame do not conflict, and that the shape and direction of the inlet cross-section of the torsion-connected chute constructed based on the frame model in subsequent steps are consistent with the shape and direction of the outlet cross-section of the upstream conveyor corresponding to the first chute inlet cross-section model, and that the shape and direction of the outlet cross-section of the torsion-connected chute are consistent with the shape and direction of the inlet cross-section of the downstream conveyor corresponding to the second chute inlet cross-section model. This reduces the installation difficulty of the manufactured connecting chute and ensures that the surfaces formed by the edges of the frame in the model, excluding the inlet and outlet cross-sections, are consistent. The simple triangular shape simplifies the design of the chute structure, reduces the amount of raw materials required for chute fabrication, and thus lowers the difficulty and cost of manufacturing the connecting chute. Filling the torsion connecting chute frame model yields the outer substrate model of the torsion connecting chute, making the model more clear and accurate for subsequent torsion connecting chute fabrication steps, further reducing the difficulty and increasing the speed of connecting chute fabrication. Encapsulating the outer substrate model of the torsion connecting chute yields the final torsion connecting chute model. Fabricating the torsion connecting chute based on this final model allows for further refinement of the connecting chute model according to actual manufacturing needs, making the torsion connecting chute fabricated based on the model more likely to meet design intent, further reducing the difficulty of connecting chute fabrication. In summary, the torsion connecting chute fabrication method and apparatus provided by this invention can reduce the difficulty and cost of connecting chute fabrication, thereby improving the efficiency of connecting chute fabrication, and can also reduce the installation difficulty of the fabricated connecting chute, thereby improving the installation efficiency of the connecting chute.

[0051] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. 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.

[0053] The terms “include,” “including,” “have,” “contain,” etc., used in this article are all open-ended terms, meaning that they include but are not limited to.

[0054] The term "and / or" as used herein includes any or all of the things mentioned.

[0055] It should be noted that the acquisition, storage, use, and processing of data in the technical solution of this invention all comply with the relevant provisions of national laws and regulations.

[0056] This invention discloses a method for manufacturing a torsion-connected chute, such as... Figure 1 As shown, the method specifically includes the following steps:

[0057] S101: Connect each vertex of the preset first chute inlet cross-section model to the two vertices closest to each other in the preset second chute inlet cross-section model to obtain a torsion connection chute frame model.

[0058] S102: Fill the torsion connection chute frame model to obtain the torsion connection chute peripheral substrate model.

[0059] S103: The outer substrate model of the torsion connection chute is encapsulated to obtain the final model of the torsion connection chute, and the torsion connection chute is fabricated based on the final model of the torsion connection chute.

[0060] The present invention provides a method and apparatus for manufacturing a torsion-connected chute. By connecting each vertex of a preset first chute inlet cross-section model to the two closest vertices of a preset second chute inlet cross-section model, a torsion-connected chute frame model is obtained. This ensures that the edges connecting the vertices in the frame do not conflict, and that the shape and direction of the inlet cross-section of the torsion-connected chute constructed based on the frame model in subsequent steps are consistent with the shape and direction of the outlet cross-section of the upstream conveyor corresponding to the first chute inlet cross-section model, and that the shape and direction of the outlet cross-section of the torsion-connected chute are consistent with the shape and direction of the inlet cross-section of the downstream conveyor corresponding to the second chute inlet cross-section model. This reduces the installation difficulty of the manufactured connecting chute and ensures that the surfaces formed by the edges of the frame in the model, excluding the inlet and outlet cross-sections, are consistent. The simple triangular shape simplifies the design of the chute structure, reduces the amount of raw materials required for chute fabrication, and thus lowers the difficulty and cost of manufacturing the connecting chute. Filling the torsion connecting chute frame model yields the outer substrate model of the torsion connecting chute, making the model more clear and accurate for subsequent torsion connecting chute fabrication steps, further reducing the difficulty and increasing the speed of connecting chute fabrication. Encapsulating the outer substrate model of the torsion connecting chute yields the final torsion connecting chute model. Fabricating the torsion connecting chute based on this final model allows for further refinement of the connecting chute model according to actual manufacturing needs, making the torsion connecting chute fabricated based on the model more likely to meet design intent, further reducing the difficulty of connecting chute fabrication. In summary, the torsion connecting chute fabrication method and apparatus provided by this invention can reduce the difficulty and cost of connecting chute fabrication, thereby improving the efficiency of connecting chute fabrication, and can also reduce the installation difficulty of the fabricated connecting chute, thereby improving the installation efficiency of the connecting chute.

[0061] In an optional implementation, it further includes:

[0062] Before connecting each vertex of the preset first chute inlet cross-section model to the two nearest vertices of the preset second chute inlet cross-section model to obtain the torsional connection chute frame model.

[0063] Based on the outlet of the upstream conveyor of the target, multiple vertices of the chute inlet section are determined, and the first chute inlet section model is formed based on the multiple vertices of the chute inlet section.

[0064] Based on the inlet of the target downstream conveyor, multiple vertices of the chute outlet section are determined, and a second chute outlet section model is formed based on the multiple vertices of the chute outlet section.

[0065] For example, determining multiple vertices of the chute inlet section based on the outlet of the upstream conveyor can be achieved, but is not limited to, determining the vertex positions and relative positions of the cross-section at the outlet of the upstream conveyor through methods such as manual surveying, sensor surveying, or modeling software sampling simulation. These positions and relative positions are then used as the positions and relative positions of the multiple vertices of the chute inlet section. Preferably, the multiple vertices of the chute inlet section can be determined by simulating the outlet of the upstream conveyor using modeling tools such as SolidWorks and CAD. It should be noted that the specific implementation method for determining multiple vertices of the chute inlet section based on the outlet of the upstream conveyor can be determined by those skilled in the art according to the actual situation. The above description is merely an example and does not constitute a limitation.

[0066] For example, determining multiple vertices of the chute outlet cross-section based on the inlet of the target downstream conveyor can be achieved, but is not limited to, determining the vertex positions and relative positions of the cross-section at the inlet of the target downstream conveyor through methods such as manual surveying, sensor surveying, and modeling software sampling simulation. These positions and relative positions are then used as the positions and relative positions of the multiple vertices of the chute outlet cross-section. Preferably, the multiple vertices of the chute outlet cross-section can be determined by simulating the inlet of the downstream conveyor using modeling tools such as SolidWorks and CAD. It should be noted that the specific implementation method for determining multiple vertices of the chute outlet cross-section based on the inlet of the target downstream conveyor can be determined by those skilled in the art according to the actual situation. The above description is merely an example and does not constitute a limitation.

[0067] For example, such as Figure 2 As shown, vertices p1, p2, p3, and p4 are multiple vertices of the chute inlet section determined based on the outlet of the upstream conveyor of the target, while vertices p5, p6, p7, and p8 are multiple vertices of the chute outlet section determined based on the inlet of the downstream conveyor of the target.

[0068] For example, the outlet of the target upstream conveyor may be, but is not limited to, the head funnel outlet of the target upstream conveyor.

[0069] For example, the inlet of the target downstream conveyor can be, but is not limited to, the feed chute opening of the target downstream conveyor.

[0070] By taking the above steps, the accuracy of the relative positional relationship between multiple vertices of the determined chute inlet section and multiple vertices of the determined chute outlet section can be improved, thereby making the determined first chute inlet section model and second chute inlet section model more accurate, which in turn improves the accuracy of the final model of the torsion connection chute determined in subsequent steps, and thus makes the torsion connection chute constructed based on the final model more in line with the design expectations.

[0071] In an optional implementation, the step of forming the first chute inlet cross-section model based on the plurality of vertices of the chute inlet cross-section includes:

[0072] A three-dimensional coordinate system is constructed with the center of the chute inlet section as the origin.

[0073] The first chute inlet cross-section model is constructed based on the coordinates of multiple vertices of the chute inlet cross-section in a three-dimensional coordinate system;

[0074] Correspondingly, the formation of the second chute outlet cross-section model based on multiple vertices of the chute outlet cross-section includes:

[0075] The second chute outlet cross-section model is constructed based on the coordinates of multiple vertices of the chute outlet cross-section in a three-dimensional coordinate system.

[0076] For example, the center can be, but is not limited to, the center of mass, the center of gravity, or the centroid, and is preferably the centroid.

[0077] For example, the positive directions of the x-axis, y-axis, and z-axis of the three-dimensional coordinate system can be determined by those skilled in the art based on actual conditions. This embodiment of the invention does not impose any limitations on this; however, the x-axis, y-axis, and z-axis must be perpendicular to each other. Preferably, the x-axis and y-axis can be parallel to the chute inlet section to facilitate the determination of the coordinates from vertex p1 to vertex p8 and subsequent processing based on these coordinates.

[0078] For example, after determining a three-dimensional coordinate system in which the x-axis and y-axis are parallel to the inlet section of the chute, it is possible to obtain, as follows: Figure 2 The coordinates of vertices p1 to p8 are shown below:

[0079] Chute inlet cross section:

[0080] p1(-262, 342, 0)

[0081] p2(262, 342, 0)

[0082] p3(262, -342, 0)

[0083] p4(-262, -342, 0)

[0084] Chute outlet cross section:

[0085] p5(920, -538, -2445)

[0086] p6(1407, -1025, -2321)

[0087] p7(1025, -1407, -2321)

[0088] p8(538, -920, -2445)

[0089] For example, constructing the first chute inlet cross-section model based on the coordinates of multiple vertices of the chute inlet cross-section in a three-dimensional coordinate system can be, but is not limited to, based on the shape of the outlet of the actual upstream conveyor. The multiple vertices of the chute inlet cross-section are sequentially connected based on the aforementioned coordinates and modified according to actual needs to construct the first chute inlet cross-section model. For example, the first chute inlet cross-section model can be constructed using modeling tools such as SolidWorks and CAD. It should be noted that the specific implementation method for constructing the first chute inlet cross-section model based on the coordinates of multiple vertices of the chute inlet cross-section in a three-dimensional coordinate system can be determined by those skilled in the art based on the actual situation. The above description is merely an example and does not constitute a limitation.

[0090] For example, constructing the second chute outlet cross-sectional model based on the coordinates of multiple vertices of the chute outlet cross-section in a three-dimensional coordinate system can be, but is not limited to, based on the shape of the inlet of the actual downstream conveyor. The multiple vertices of the chute outlet cross-section are sequentially connected based on the aforementioned coordinates and modified according to actual needs to construct the second chute outlet cross-sectional model. For example, the second chute outlet cross-sectional model can be constructed using modeling tools such as SolidWorks and CAD. It should be noted that the specific implementation method for constructing the second chute outlet cross-sectional model based on the coordinates of multiple vertices of the chute outlet cross-section in a three-dimensional coordinate system can be determined by those skilled in the art based on the actual situation. The above description is merely an example and does not constitute a limitation.

[0091] Through the above steps, the positional information of the vertices required to construct the chute inlet cross-section can be quantified into accurate coordinates. This enables more accurate, faster, and more convenient positioning when constructing the chute inlet cross-section model, thereby indirectly reducing the difficulty of manufacturing connecting chutes, improving the speed and accuracy of manufacturing connecting chutes, and ultimately indirectly improving the efficiency of manufacturing connecting chutes.

[0092] In an optional implementation, the step of connecting each vertex of a preset first chute inlet cross-section model to the two closest vertices of a preset second chute inlet cross-section model to obtain a torsion-connected chute frame model includes:

[0093] Select a first starting vertex from the vertices of the first chute inlet cross-section model, and determine the vertex of the second chute inlet cross-section model that is closest to the first starting vertex as the second starting vertex;

[0094] Using the first starting vertex as the first selected vertex and the second starting vertex as the second selected vertex, a misaligned connection operation is performed. The misaligned connection operation includes:

[0095] Based on the first selected vertex, determine the first target vertex in the first chute cross-section model that is adjacent to the first target vertex in the preset target direction, connect the second selected vertex and the first target vertex, and based on the second selected vertex, determine the second target vertex in the second chute cross-section model that is adjacent to the second target vertex in the target direction, connect the second target vertex and the first target vertex.

[0096] Using the first target vertex as the first selected vertex and the second target vertex as the second selected vertex, the misaligned connection operation is repeated until the first starting vertex is connected to the second starting vertex, thus obtaining the torsion connection chute frame model.

[0097] For example, the target direction can be, but is not limited to, circumferential, such as counterclockwise circumferential and clockwise circumferential, preferably counterclockwise circumferential.

[0098] For example, such as Figure 3 As shown, if the first starting vertex is vertex p1, then the vertex closest to the first starting vertex in the second chute cross-section model is p5, and vertex p5 is the second starting vertex.

[0099] For example, such as Figure 3 As shown, the misaligned connection operation has the following examples:

[0100] When the first starting vertex is determined to be vertex p1 and the second starting vertex to be vertex p5, vertex p1 is selected as the first vertex and vertex p5 as the second vertex. At this point, the first target vertex adjacent to vertex p1 in the clockwise circumferential direction (assuming the target direction is this direction) is p2, so vertex p5 and vertex p2 are connected. The second target vertex adjacent to vertex p5 in the clockwise circumferential direction is p6, so vertex p6 and vertex p2 are connected. Then, vertex p2 is selected as the first vertex and vertex p6 as the second vertex, and the staggered connection operation continues until vertex p1 is connected to vertex p5, ending the loop of the staggered connection operation as follows: Figure 3The torsion connection chute frame model is shown. The principle behind subsequent misaligned connection operations is the same as described above, and will not be repeated here. It should be noted that the specific implementation method of the misaligned connection operation can be determined by those skilled in the art based on the actual situation; the above description is merely an example and does not constitute a limitation.

[0101] Corresponding to the example of the misaligned connection operation above, the misaligned connection operation can also be understood as follows:

[0102] like Figure 3 As shown, starting from vertices p1 and p5 respectively, the following two vertex sequences are defined for the first and second chute inlet cross-section models in a clockwise circumferential direction:

[0103] The order of the vertices of the first chute inlet section is: p1→p2→p3→p4;

[0104] The order of the vertices of the second chute inlet section is: p5→p6→p7→p8;

[0105] Among them, p1 corresponds to p5, p2 corresponds to p6, p3 corresponds to p7 and p4 corresponds to p8.

[0106] Based on the above order and correspondence, vertices p1 and p5, p5 and p2, p2 and p6, p6 and p3, p3 and p7, p7 and p4, p4 and p8, and p8 and p1 are connected by straight lines in a staggered manner, thus obtaining the torsion connection chute frame model.

[0107] The above steps can improve the speed of building the framework model and reduce the probability of errors during the model building process. A simple and feasible framework model building scheme is provided, which can reduce the difficulty and procedures of building the framework model. This eliminates the need for workers to worry about potential conflicts between the edges of the framework during model building. Furthermore, the framework formed by the above steps can minimize the wall area of ​​the connecting pipes formed in subsequent steps and make them simple and easy to manufacture, thereby indirectly reducing the difficulty and cost of manufacturing connecting pipes and improving the efficiency of manufacturing connecting pipes.

[0108] In one alternative implementation, such as Figure 4 As shown, selecting the first starting vertex from the vertices of the first chute outlet cross-section model includes the following steps:

[0109] S401: Take the center of the second chute outlet cross-section model as the starting reference point.

[0110] S402: Determine the vertex of the first chute cross-section model that is farthest from the starting reference point as the first starting vertex.

[0111] For example, the center can be, but is not limited to, the center of mass, the center of gravity, or the centroid, and is preferably the centroid.

[0112] For example, determining the vertex furthest from the starting reference point among the vertices of the first chute outlet cross-section model as the first starting vertex can be achieved, but is not limited to, by automatic calculation using modeling software or by calculation based on coordinates. It should be noted that the specific implementation of step S402 can be determined by those skilled in the art based on actual circumstances; the above description is merely an example and does not constitute a limitation.

[0113] By using steps S401 and S402, a suitable first starting vertex can be selected based on relevant geometric principles and properties, thereby reducing the difficulty of determining the connection of the chute frame model in subsequent steps. This further improves the speed and efficiency of establishing the torsion connection chute frame model, and indirectly improves the efficiency of making torsion connection chute based on the model in subsequent steps.

[0114] In an optional implementation, filling the torsion-connected chute frame model to obtain the torsion-connected chute peripheral substrate model includes:

[0115] The boundary is filled with the connecting lines formed by the edges and all vertices of the first and second chute cross-section models to obtain the outer substrate model of the torsion connection chute.

[0116] For example, by Figure 3 The torsion connection chute frame model shown can determine the connecting lines formed between all vertices, including: line p1-p5, line p5-p2, line p2-p6, line p6-p3, line p3-p7, line p7-p4, line p4-p8, and line p8-p1.

[0117] The edges of the first chute inlet cross-section model include: lines p1-p2, p2-p3, p3-p4, and p4-p1. The edges of the second chute inlet cross-section model include: lines p5-p6, p6-p7, p7-p8, and p8-p5.

[0118] For example, the filling with the lines formed by connecting each edge and all vertices of the first and second chute inlet cross-section models as boundaries can be understood as, but is not limited to, filling all surfaces (the pipe wall surfaces) of the frame model except for the chute inlet cross-section.

[0119] For example, the color used for filling can be, but is not limited to, black, gray, or blue.

[0120] It should be noted that the specific implementation method of filling with the lines formed by connecting each edge and all vertices of the first and second chute cross-section models as boundaries, as well as the color used for filling, can be determined by those skilled in the art based on the actual situation. The above description is only an example and does not constitute a limitation.

[0121] By following the steps above, the accuracy of the infill frame model can be improved, and the probability of mistakenly filling the chute inlet section can be reduced. This will improve the accuracy and correctness of the final torsion connection chute model obtained in subsequent steps, and thus improve the accuracy of the connection chute fabrication based on the final model.

[0122] In one alternative implementation, such as Figure 5 As shown, the process of encapsulating the outer substrate model of the torsion connection chute to obtain the final model of the torsion connection chute includes the following steps:

[0123] S501: Thicken each substrate in the outer substrate model of the torsion connection chute to obtain the first intermediate model.

[0124] S502: Construct a flange model corresponding to the first chute opening cross-section model at the first intermediate model to obtain the second intermediate model.

[0125] S503: Construct a liner model corresponding to the inner surface of each substrate of the second intermediate model to obtain the final model of the torsion connection chute.

[0126] For example, each substrate is specifically each substrate constituting the sidewall of the chute in the torsion connection chute peripheral substrate model.

[0127] For example, the thickening of each substrate in the outer substrate model of the torsion connection chute can be achieved through corresponding functions in existing modeling software, but not limited to.

[0128] For example, the direction of the thickening can be, but is not limited to, thickening outward or thickening inward, with thickening outward being preferred.

[0129] For example, the thickness of the substrate after the thickening treatment (the wall thickness of the twisted connection chute) can be, but is not limited to, 5 mm to 16 mm, preferably 8 mm.

[0130] It should be noted that the specific implementation of step S501 can be determined by those skilled in the art based on the actual situation. The above description is only an example and does not constitute a limitation.

[0131] For example, constructing a flange model corresponding to the first chute opening cross-section model in the first intermediate model can be achieved using, but is not limited to, the corresponding function in existing modeling software. The flange model can be constructed by, but is not limited to, using any three vertices from the multiple vertices of the first chute opening cross-section model to form a reference surface, and using this reference surface as the sketch reference surface. It should be noted that the specific implementation of step S502 can be determined by those skilled in the art based on actual circumstances; the above description is merely an example and does not constitute a limitation.

[0132] Through steps S501 to S503, the model of the torsion connection chute can be further improved, so that each component and corresponding connection relationship in the torsion connection chute model is as complete as possible. This makes it easier for the torsion connection chute made based on the model to meet the design intent. Furthermore, making the torsion connection chute based on a more complete model can effectively reduce the difficulty of making the torsion connection chute and increase the production speed.

[0133] In an optional implementation, the step of constructing a liner model corresponding to the inner surface of each substrate of the second intermediate model to obtain the final model of the torsion connection chute includes:

[0134] A liner model of a predetermined thickness is formed using the inner surface of each substrate as a reference surface; wherein the size of the liner model is smaller than the size of the corresponding substrate.

[0135] For example, the preset thickness can be, but is not limited to, 5mm to 50mm, preferably 20mm.

[0136] For example, the step of forming a liner model with a preset thickness using the inner surface of each substrate as a reference plane can be, but is not limited to, using the inner surface of each substrate as a reference plane, offsetting each edge of that surface inward by a certain dimension to obtain a sketch of the liner outline, and then stretching the liner model towards the pipe axis based on the sketch of the liner outline and the preset thickness. The above operations can be implemented using, but are not limited to, corresponding functions in existing modeling software. In actual manufacturing of torsion connection chutes, the liner can also be formed by dividing wear-resistant steel or ceramic sheets into blocks of a certain size, and then fully covering the inner wall of the chute with the divided products. It should be noted that the specific implementation of forming a liner model with a preset thickness using the inner surface of each substrate as a reference plane can be determined by those skilled in the art based on the actual situation; the above description is merely an example and does not constitute a limitation.

[0137] By following the above steps, the liner model can be prevented from overlapping with the base plate model and flange model in the second intermediate model, thereby reducing the probability of errors in the final model of the torsion connection chute and improving the accuracy of the torsion connection chute manufactured based on the final model of the torsion connection chute.

[0138] Based on the same principle, this invention discloses a torsion connection chute manufacturing device 600, such as... Figure 6 As shown, the torsion connection chute manufacturing apparatus 600 includes:

[0139] The torsion connection chute frame model construction module 601 is used to connect each vertex of the preset first chute inlet cross-section model to the two closest vertices in the preset second chute inlet cross-section model to obtain the torsion connection chute frame model.

[0140] The outer substrate model construction module 602 for twisted connection chute is used to fill the frame model of the twisted connection chute to obtain the outer substrate model of the twisted connection chute.

[0141] The final model construction module 603 for twisted connection chute is used to encapsulate the outer substrate model of the twisted connection chute to obtain the final model of the twisted connection chute, so as to manufacture the twisted connection chute based on the final model of the twisted connection chute.

[0142] In an optional implementation, a chute orifice cross-section model forming module is also included, for:

[0143] Before connecting each vertex of the preset first chute inlet cross-section model to the two nearest vertices of the preset second chute inlet cross-section model to obtain the torsional connection chute frame model.

[0144] Based on the outlet of the upstream conveyor of the target, multiple vertices of the chute inlet section are determined, and the first chute inlet section model is formed based on the multiple vertices of the chute inlet section.

[0145] Based on the inlet of the target downstream conveyor, multiple vertices of the chute outlet section are determined, and a second chute outlet section model is formed based on the multiple vertices of the chute outlet section.

[0150] The second chute outlet cross-section model is constructed based on the coordinates of multiple vertices of the chute outlet cross-section in a three-dimensional coordinate system.

[0151] In an optional implementation, the torsion connection chute frame model building module is used for:

[0152] Select a first starting vertex from the vertices of the first chute inlet cross-section model, and determine the vertex of the second chute inlet cross-section model that is closest to the first starting vertex as the second starting vertex;

[0153] Using the first starting vertex as the first selected vertex and the second starting vertex as the second selected vertex, a misaligned connection operation is performed. The misaligned connection operation includes:

[0154] Based on the first selected vertex, determine the first target vertex in the first chute cross-section model that is adjacent to the first target vertex in the preset target direction, connect the second selected vertex and the first target vertex, and based on the second selected vertex, determine the second target vertex in the second chute cross-section model that is adjacent to the second target vertex in the target direction, connect the second target vertex and the first target vertex.

[0155] Using the first target vertex as the first selected vertex and the second target vertex as the second selected vertex, the misaligned connection operation is repeated until the first starting vertex is connected to the second starting vertex, thus obtaining the torsion connection chute frame model.

[0156] In an optional implementation, the torsion connection chute frame model building module is used for:

[0157] The center of the second chute inlet cross-section model is taken as the starting reference point;

[0158] The vertex furthest from the starting reference point among the vertices of the first chute inlet cross-section model is determined as the first starting vertex.

[0159] In an optional implementation, the torsion connection chute peripheral substrate model building module is used for:

[0160] The boundary is filled with the connecting lines formed by the edges and all vertices of the first and second chute cross-section models to obtain the outer substrate model of the torsion connection chute.

[0162] Each substrate in the outer substrate model of the torsion connection chute is thickened to obtain the first intermediate model;

[0163] A flange model corresponding to the first chute inlet cross-section model is constructed at the first intermediate model to obtain the second intermediate model;
