Description

Technical Field

[0001] The invention relates to the technical field of steel structure modeling building production, in particular to a production method of a small-section bending-torsion member. Background Art

[0002] With the development of modern technology, in order to show a visual impact to tourists, more and more architectural designs tend to have the angular beauty of rectangular bending moments. Therefore, there are more small-section rectangular tubes in the external supports of the shaped buildings.

[0003] In the prior art, the production of small-section rectangular tubes has a long production cycle and high production cost. Patent application number CN104259273A discloses a method for processing bending and torsion components of steel structure engineering, and the steps are as follows: 1) making a top bending device for rectangular-section steel components; 2) adjusting the positions of three limit seats; 3) placing the rectangular-section steel component to be bent between the top bending seat and the three limit seats; 4) using a jack to bend the rectangular-section steel component to be bent; 5) making a steel structure component twisting device; 6) adjusting the positions of the left support, the middle support and the right support on the guide rail; 7) placing the bent rectangular-section steel component in the bayonet on the left support, the middle support and the right support and fixing it.

[0004] The disclosed patent uses a jack to bend the rectangular section to make a twisting device for steel structure components to improve the accuracy of manufacturing rectangular cross-section pipe fittings. However, due to the large number of small-section rectangular tubes and the overlap of points on the precise coordinate drawings, it is difficult to distinguish the specific coordinates of each edge on the conventional coordinate point drawings, and the production process of a single bending torque is complicated. The disclosed patent cannot reduce the production steps of multiple bending and twisting components, resulting in low production efficiency and the expression method of the coordinate point drawings of small-section components.

[0042] The technical solution of the present invention will be further described below with reference to the accompanying drawings and through specific implementation methods.

[0043] Example 1, as Figures 1 to 3 As shown, a method for producing a small-section bending-torsion member includes the following steps:

[0044] Step L1: Prepare a pre-processing drawing of the bending-torsion component and a coordinate point diagram of the bending-torsion component;

[0045] Step L2: performing a first processing on the bending-torsion member body according to the bending-torsion member pre-processing drawing to obtain a bending-torsion member rough-processing member;

[0046] Step L3: constructing a bending-torsion member frame according to the bending-torsion member coordinate point diagram;

[0047] Step L4: According to the bending-torsion member coordinate point diagram, the bending-torsion member rough-machined member is subjected to a second processing through the bending-torsion member jig to form a bending-torsion member 1.

[0048] In this embodiment, the method of the present application can achieve rapid and efficient production of each bending-torsion member 1, and the preparation of the bending-torsion member pre-processing drawing and the bending-torsion member coordinate point diagram can achieve overall control of the required bending-torsion member, which can simplify the steps of manufacturing the bending-torsion member 1.

[0049] In step 11, the specific steps of preparing the bending-torsion member coordinate point diagram and the bending-torsion member pre-processing diagram include:

[0050] L11: Determine the parameters of the bending-torsion member 1 to be produced;

[0051] L12: Modeling and marking the bending-torsion member 1 according to the parameters;

[0052] L13: Printing a drawing of the bending-torsion component 1 in L12 to form a pre-processing drawing of the bending-torsion component;

[0053] L14: Mark the production coordinates of the bending-torsion member 1 in L13 and print the drawing to form the bending-torsion member coordinate point diagram.

[0054] In step 111, the specific parameter is the actual length of the small-section rectangular tube required for the desired bending-torsion member 1. Both the production marking and installation marking of the desired length of the small-section rectangular tube are marked on the tube. The production marking specifically refers to the location where bending is required (i.e., the bending position marking), the degree of bending (the bending degree marking), and the direction of bending (the bending direction marking). The installation marking specifically refers to the bending-torsion member installation direction marking and the bending-torsion member installation connection marking. These parameters are marked on the corresponding locations of the bending-torsion member 1 to serve as markers for subsequent processing. The parameters are set in advance based on the actual needs of the bending-torsion member 1, and then the bending-torsion member 1 is modeled based on these parameters. Assuming that the desired bending-torsion member 1 requires a 20m long small-section rectangular tube, to achieve accurate modeling, the actual small-section rectangular tube length and the length of the small-section rectangular tube in the drawing are modeled in Rhino software at a ratio of 1:10. Therefore, a 2000mm long small-section rectangular tube is drawn in the drawing and marked accordingly based on the determined parameters to obtain the corresponding bending-torsion member 1. The bending-torsion member 1 modeled by Rhino software is printed to form a detailed drawing that can guide processing, that is, the bending-torsion member pre-processing drawing can be obtained.

[0055] Because a small-cross-section rectangular tube is used, the rough-finished bending-torsion component obtained by only performing the first treatment will not be dimensionally consistent with the desired bending-torsion component 1. Furthermore, directly subjecting the obtained bending-torsion component body to flame or external force treatment will easily cause cross-sectional deformation of the bending-torsion component. Therefore, a professional manufacturer must first perform the first treatment on the bending-torsion component body according to the bending-torsion component pre-processing drawing, and then perform the second treatment on the rough-finished bending-torsion component to obtain the desired bending-torsion component 1. At this time, in order to improve the production efficiency of the bending-torsion component 1, the rough-finished bending-torsion component must be marked with production coordinates. The specific process of producing coordinate marking is to first determine the three-dimensional coordinates (X-axis direction, Y-axis direction and Z-axis direction) of the rough-processed component of the bending and torsion component, wherein the X-axis is the length direction of the bending and torsion component 1, the Y-axis is the width direction of the bending and torsion component 1, and the Z-axis is the bending depth of the bending and torsion component 1 in the vertical direction; then, in order to improve the production efficiency of the bending and torsion component 1, when the coordinates of the rough-processed component of the bending and torsion component are marked, the X-axis adopts equidistant marking, which can be specifically 500mm, and the Y-axis spacing marking is carried out using the maximum width of the required bending and torsion component 1 on the Y-axis. The Z-axis sets the corresponding Z-axis height according to the bending degree of each X-axis marking point; finally, the rough-processed component of the bending and torsion component after coordinate marking is printed as a drawing to form a coordinate point diagram of the bending and torsion component for guiding processing. Conventional coordinate point drawings use a single number to express the coordinate corresponding to the size of a certain position in the component. When the cross-section of the bending-torsion component is very small, the lines in the bending-torsion component drawings overlap, the numbers are not distinguished, and it is difficult to distinguish. Therefore, the four edges of the rough-processed bending-torsion component described in this application are marked with different letters to distinguish them, that is, A, B, C, and D are used to mark the four edges of the bending-torsion component 1 counterclockwise.

[0056] In order to make the bending and torsion member 1 more accurate, the coordinate markings of the rough-processed bending and torsion member are made by using edge letters plus numbers of each coordinate as the coordinate markings of the rough-processed bending and torsion member. The overlapping lines and indistinguishable coordinate points in the drawings do not affect the production of the member, and the processing operation is convenient. In this application, the production coordinate system of the bending and torsion member 1 is consistent with the order of its installation direction. Therefore, when marking the bending and torsion member 1, each bending and torsion member 1 is marked with breakpoint coordinates according to its X-axis, Y-axis, and Z-axis. The coordinates in the X-axis direction are marked with a coordinate point at intervals of 500mm. The initial position of the bending and torsion member 1 is marked as (01) until the last position (max) of the bending and torsion member 1. Here, the intervals of the X-axis are divided into equal intervals. As Figure 2 and Figure 3As shown, each bending and torsion member 1 must be marked with the installation direction and the bending and torsion member installation connection mark. Assuming that a building requires 30 meters of bending and torsion members, for ease of transportation, the 30-meter bending and torsion members are divided into a 17-meter first bending and torsion member 1-1 and a 13-meter second bending and torsion member 1-2, which are then manufactured separately. After completion, they are then assembled on-site to form the required bending and torsion members. To facilitate on-site installation, the first bending and torsion member 1-1 and the second bending and torsion member 1-2 need to be marked for installation to facilitate installation. As shown in the figure, the coordinate points on the first bending and torsion member 1-1 and the second bending and torsion member 1-2 are evenly spaced on the X-axis. During on-site installation, it is only necessary to align the Amax end of the first bending and torsion member 1-1 with the A01 end of the adjacent second bending and torsion member 1-2. At this time, when the first bending and torsion member 1-1 and the adjacent second bending and torsion member 1-2 are aligned, the edges with the same letters should be aligned. The total bending and twisting member that may be required for actual construction needs may be longer, and it may be necessary to connect multiple bending and twisting members 1 to meet the requirements. The connection method of two adjacent bending and twisting members can be simple to install on site according to the installation direction mark and the bending and twisting member installation connection mark. Of course, when making multiple bending and twisting members 1, make good serial number marks, put the multiple bending and twisting members 1 that are connected together together, and mark them according to the serial number, such as Figure 2 and Figure 3 The markings on the first bending-torsion member 1-1 and the second bending-torsion member 1-2 can avoid installation errors during on-site installation.

[0057] In step L2, the specific steps of forming the bending-torsion member body are:

[0058] L21: According to the required unfolded length of the bending and torsion member, the small-section rectangular tube is cut or butted to obtain the small-section rectangular tube body;

[0059] L22: The small-section rectangular tube body is subjected to installation marking and processing marking to form the bending-torsion member body.

[0060] In this embodiment, in step 121, it is assumed that the unfolded length of the first bending-torsion member 1-1 to be manufactured needs to be 17m. At this time, the small-section rectangular tubes available on the market will be cut or butt-welded to obtain small-section rectangular tube bodies of the same length; in step 122, the small-section rectangular tube bodies are marked for installation mainly to facilitate on-site installation.

[0061] In step L2, the first treatment of the bending-torsion member body is specifically to perform cold bending or hot bending pre-processing on the treatment mark of the bending-torsion member body to obtain the bending-torsion member rough-processed member. In this embodiment, directly using flame and external force to adjust the bending-torsion member body with a very small bending degree is prone to bending of the small-section rectangular tube of the bending-torsion member body. Therefore, a professional manufacturer is required to use an arc machine to perform single-direction or multi-direction cold bending according to the bending-torsion member pre-processing drawing to obtain the bending-torsion member rough-processed member. For some bending-torsion member bodies with larger bending arcs, it is necessary to use a cold-bending arc top bending machine to process the bending-torsion member body according to the drawing, so as to obtain the bending-torsion member rough-processed member corresponding to the bending-torsion member pre-processing drawing. The chord length and height of the bending-torsion member rough-processed member in its four directions are consistent with the bending-torsion member pre-processing drawing.

[0062] In the step L3, the bending-torsion member cradle is constructed according to the bending-torsion member coordinate point diagram to facilitate the formation of the bending-torsion member 1. The specific process of constructing the bending-torsion member cradle is as follows: L31: setting a cradle support base 2, and the cradle support base 2 can be adjusted according to the size of the required bending-torsion member 1; L32: setting at least two rows of support plate groups on the cradle support base 2; L33: setting a support rod 4 between two adjacent support plate groups, and the first axial end of the support rod 4 is connected to a support plate 3 in the first row of support plate groups, and the second axial end is connected to the corresponding support plate 3 in the second row of support plate groups. The two rows of support plate groups can build a bending-torsion member 1, and the cradles required for multiple bending-torsion members 1 can be combined. Two adjacent support plate groups can be shared to improve the reuse rate of the bending-torsion member cradle and reduce the production efficiency of the bending-torsion member 1. Mark the different bending-torsion members 1 required for the same building, and then build the cradle corresponding to the required bending-torsion member 1. For example Figure 1 As shown, the bending and torsion members 1 and 5 can be the bending and torsion members required for the same building. It is only necessary to adjust the height of the support rod 4 from the tire frame support base 2 according to the vertical bending degree of the corresponding bending and torsion member. During on-site assembly, it can be installed according to the installation markings.

[0063] In the step L32, the two adjacent support plates in each row of the support plate group are arranged at equal intervals to achieve the reuse of the bending-torsion member frame. It is only necessary to control the distance from the support rod 4 to the frame support base (i.e., the coordinate of the Z axis) according to the bending-torsion member coordinate point diagram to limit the rough-processed components of the bending-torsion member to facilitate the formation of the bending-torsion member 1.

[0064] In step L4, the second processing of the rough-machined bending and torsion member specifically includes the following steps:

[0065] L41: placing the rough-processed bending-torsion member on the bending-torsion member jig according to the bending-torsion member coordinate point diagram;

[0066] L42: flame heating the bending-torsion member at corresponding positions according to the bending-torsion member coordinate point diagram;

[0067] L43: Welding the pressure plate in place after heating;

[0068] L44: Repeat L42 to L43 until the entire bending-torsion member 1 is processed at the processing mark;

[0069] L45: Leave the entire bending-torsion member on the bending-torsion member stand for a period of time;

[0070] L46: Finally, transplant the end identification and component number of the bending-torsion component into the rectangular tube of the bending-torsion component 1.

[0071] In this embodiment, according to the bending and torsion member coordinate diagram, the rough-finished bending and torsion member is processed using the bending and torsion member jig to form the bending and torsion member 1. The rough-finished bending and torsion member is heated using a flame at the marked locations on the jig. Then, using an external force tool such as a ziplock, the heated rough-finished bending and torsion member is aligned with the coordinates marked on the jig. A plate is spot-welded above the rough-finished bending and torsion member to secure it to the jig. This localized heating relieves internal stress within the rectangular tube of the rough-finished bending and torsion member, resulting in a highly precise bending and torsion member 1. In the first step, all rough-finished bending and torsion member components required for the same bending and torsion member 1 are placed on the jig according to their port numbers, arranged in ascending order. In the second step, the rough-finished bending and torsion member is flame-heated at the marked locations according to the bending and torsion member coordinate diagram to form a preliminary bending and torsion member. After heating, a pressure plate is welded to the upper end of the preliminary bending and torsion member. This allows the heated portion of the preliminary bending and torsion member to dissipate heat within the pressure plate, achieving the bending and torsion degree required by the bending and torsion member coordinate diagram. The third step is to repeat the steps L42 to L43 until the entire preliminary bending-torsion member 1 is processed according to the bending-torsion member coordinate point diagram. The fourth step is to place the entire bending-torsion member 1 on the bending-torsion member frame for a period of time, generally six to seven hours, so that it can be formed to obtain a complete bending-torsion member 1. The fifth step is to use a paint pen to mark directly on the outer wall of the small-section rectangular tube for the convenience of the operator to check during the production process. However, after a whole bending-torsion member 1 is made, the end mark of each bending-torsion member 1 and the number of each bending-torsion member 1 need to be transplanted to the inside of the rectangular tube of the bending-torsion member 1 for easy search during use and to avoid the end mark and member number mark of the bending-torsion member being worn out, which affects the use of the bending-torsion member 1. Due to engineering needs, part of the second bending-torsion member segment may be bent 180 degrees, but the other second bending-torsion member segment adjacent to it can still be welded within the error range.

[0072] In the present application, the bending-torsion member frames of multiple bending-torsion members 1 can be combined together, so multiple bending-torsion members 1 can be processed simultaneously according to the bending-torsion member pre-processing drawing and the bending-torsion member coordinate point diagram. As long as the same bending-torsion member required for the construction is segmented into multiple bending-torsion members 1 during the processing and transportation process, and then these bending-torsion members 1 are transported to the construction site for splicing, it is only necessary to classify and mark these multiple bending-torsion members 1 during production, and do the following: Figure 2 and Figure 3 In this application, each bending and torsion member 1 and its corresponding tire frame can be marked with a capital number to prevent errors in processing.

[0073] Example 2, a bending-torsion member tire frame, in the production method of the bending-torsion member 1 in Example 1, the bending-torsion member tire frame includes

[0074] The tire frame base 2 is in contact with the ground;

[0075] At least two rows of support plate groups, each comprising a plurality of support plates 3 arranged in an interval, the bottoms of each support plate 3 being connected to the tire frame base 2;

[0076] The support rod 4 is arranged between two adjacent rows of support plate groups and is used to support the bending-torsion member 1, and the first axial end of the support rod 4 is connected to a support plate 3 in the first row of support plate groups, and the second axial end is connected to the corresponding support plate 3 in the second row of support plate groups.

[0077] In this embodiment, the manufactured bending-torsion member tire frame can be reused, reducing the manufacturing process of the bending-torsion member 1. The tire frame base 2 is in contact with the ground and can be connected to the ground by screws to avoid unstable installation when installing the third bending-torsion member segment. The two rows of support plate groups can fix one bending-torsion member 1. If the tire frames of multiple bending-torsion members 1 are placed together, the installation of the tire frames of multiple bending-torsion members 1 can be simplified. The distances between the support rods and the tire frame base 2 are all different, and are all set according to the bending-torsion member coordinate point diagram. For places where the bending-torsion member 1 is bent too much, the support rods 4 need to be at a greater distance from the tire frame base 2.

[0078] In order to reduce the construction process of the bending-torsion member frame, the plate spacing between two adjacent support plates 3 in each row of the support plate group is the same, and the distance between the corresponding support plates 3 in two adjacent rows of support plate groups is set according to the required maximum width of the bending-torsion member 1. In this way, for different roots of bending-torsion members 1, there is no need to remove the support plates 3. It is only necessary to set the support rods 4 of different heights according to the bending-torsion member coordinate point diagram, so as to maximize the use of the bending-torsion member frame to manufacture bending-torsion members 1 with different bending and torsion degrees.
