Furthermore, large space structures require a large amount of tubular materials.

If the pre-formed tube plates are manufactured in orbit via rocket transport, it would require building molding molds in space and completing welding in space, further increasing manufacturing difficulty and costs.

Detailed Implementation

[0070] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0071] Method Example 1:

[0072] like Figures 1 to 5 As shown, a first embodiment of the on-orbit composite molding method for tubular profiles of the present invention, which combines ground and space features, includes the following steps:

[0073] S1: Using equipment on the ground to bend the sheet metal into pipes;

[0074] S2: Weld or interlock the two broken edges of the pipe fitting after bending to form a closed pipe fitting profile.

[0075] S3: Use equipment to flatten all pipe profiles to form flat material with a gap at least at one end;

[0076] S4: Connect the ends of each flat material in batches and wind them into multiple rolls;

[0077] S5: Stack all rolls of material within the launch vehicle's carrying space and secure them.

[0078] S6: Use a launch vehicle to transport all rolls of material to the designated space in space;

[0079] S7: Using equipment in space to straighten all rolled materials and restore them to flat materials;

[0080] S8: Use equipment to reconstruct the flat material into the required pipe fitting profile;

[0081] S9: Stack all pipe fittings and profiles.

[0082] This method involves first molding the required tubular profiles on the ground using relevant equipment. Then, the tubular profiles are flattened into flat materials with at least one slit at one end. These flat materials are then stacked on the ground within the launch vehicle's payload space. After the rolls are transported to the designated space in space, the flat materials are restored to the required tubular profiles in space. Pre-molding the tubular profiles on the ground eliminates the need for complex processes such as building molding molds and performing welding in space, significantly reducing manufacturing difficulty and costs. Flattening the tubular profiles into flat materials with at least one slit at one end greatly saves launch space, allowing for the transport of more flat materials in a single trip. Further winding the flat materials into multiple rolls solves the problem of space occupation due to the length of the tubular profiles, further saving space. Finally, restoring the flat materials to the required tubular profiles in space allows for immediate use. Essentially, on-orbit manufacturing only requires simple restoration equipment, reducing manufacturing difficulty and costs while ensuring that manufacturing does not negatively impact the space environment.

[0083] In this embodiment, a device is used to pressurize fluid through the gap at the end of the flat material to reshape it into the desired pipe profile. This method, which utilizes pressurized fluid injected through the gap at the end of the flat material to reshape it into the desired pipe profile, is convenient and reliable to operate.

[0084] In this embodiment, a device can also be used to extend through the gap at the end of the flat material to bulge and reshape it into the desired pipe profile. This method, which uses bulging to reshape the flat material into the desired pipe profile, is convenient and reliable.

[0085] In this embodiment, equipment is also used to extrude the flat material from its narrow edge to restore it to the desired pipe profile. This method, which uses extrusion to restore the flat material to the desired pipe profile, is convenient and reliable.

[0086] In this embodiment, the wide edge of the flat material is also stretched and shaped using equipment to restore the flat material to the desired pipe profile. This method, which uses a stretching and shaping technique to restore the flat material to the desired pipe profile, is convenient and reliable.

[0087] like Figure 6 As shown, a second embodiment of the on-orbit composite molding method for the tubular profiles of the present invention, which combines ground and space features, includes the following steps:

[0088] S1: Using equipment on the ground to bend the sheet metal into pipes;

[0089] S2: Weld or interlock the two broken edges of the pipe fitting after bending to form a closed pipe fitting profile.

[0090] S3: Use equipment to flatten all pipe profiles to form flat material with a gap at least at one end;

[0091] S4: Stack the flat materials from bottom to top in batches to form multiple bundles of material;

[0092] S5: Stack all materials within the launch vehicle's payload space and secure them.

[0093] S6: Use a launch vehicle to transport all the materials to the designated space in space;

[0094] S7: Use equipment to restore all the flat materials in each bundle of stacked materials into the required pipe profiles;

[0095] S8: Stack all pipe fittings and profiles.

[0096] This method involves first molding the required tubular profiles on the ground using relevant equipment. Then, the tubular profiles are flattened into flat materials with at least one slit at one end. These flat materials are then stacked on the ground within the launch vehicle's payload space. After the roll material is transported to the designated space in space, the flat materials are restored to the required tubular profiles in space. Pre-molding the tubular profiles on the ground eliminates the need for complex processes such as building molding molds and performing welding in space, significantly reducing manufacturing difficulty and costs. Flattening the tubular profiles into flat materials with at least one slit at one end saves considerable space, allowing for the transport of more flat materials in a single trip. Finally, restoring the flat materials to the required tubular profiles in space enables them to be used immediately. This means that on-orbit manufacturing only requires simple restoration equipment, reducing manufacturing difficulty and costs while ensuring that manufacturing does not negatively impact the space environment.

[0097] Device Example 1:

[0098] like Figure 7 and Figure 8As shown, a first embodiment of the forming apparatus of the present invention for realizing the above-mentioned on-orbit composite forming method of tubular profiles in both ground and space includes a machine base 1. The machine base 1 is equipped with a positioning mechanism 2 for positioning both ends of a flat material. The machine base 1 is also equipped with a pressure fluid mechanism 3 connected to the positioning mechanism 2, which pressurizes the flat material through the gaps at the ends of the flat material to restore it to the desired tubular profile. In this structure, the machine base 1 serves as the mounting base for the positioning mechanism 2 and the pressure fluid mechanism 3. The positioning mechanism 2 positions the flat material, and then the pressure fluid mechanism 3 is activated, pressing pressure fluid through the gaps at the ends of the flat material to restore it to the desired tubular profile. Its structure is simple and reliable.

[0099] In this embodiment, the positioning mechanism 2 includes two positioning platforms 21 and two elastic sealing sleeves 22. Both positioning platforms 21 are mounted on the machine base 1. The two elastic sealing sleeves 22 are fixed to the corresponding positioning platforms 21 and sealed to the flat material port. The pressure fluid mechanism 3 connects to one positioning platform 21 and pressurizes the gap in the flat material port at that end with pressure fluid. In this structure, the elastic sealing sleeves 22 are fixed to the positioning platforms 21, and the elastic sealing sleeves 22 deform as the flat material expands, ensuring sealing and pressure. Its structure is simple and ingenious.

[0100] In this embodiment, the pressure fluid mechanism 3 includes a hydraulic cylinder 31 and a pressure pipe 32. The hydraulic cylinder 31 is mounted on the machine base 1, and one end of the pressure pipe 32 is connected to the hydraulic cylinder 31, while the other end is connected to the positioning table 21, which presses high-pressure oil into the gap of the flat material port at that end. Liquid filling makes its operation convenient and reliable.

[0101] Device Example 2:

[0102] like Figure 9 and Figure 10 As shown, this invention provides a second embodiment of the forming apparatus for implementing the above-mentioned on-orbit composite forming method for tubular profiles in both ground and space. This forming apparatus is essentially the same as that in Embodiment 1, except that: in this embodiment, the pressure fluid mechanism 3 includes a cylinder 33 and a pressure pipe 32. The cylinder 33 is mounted on the machine base 1, and one end of the pressure pipe 32 is connected to the cylinder 33, while the other end is connected to the positioning table 21, which pressurizes high-pressure gas into the gap at the flat material port. Gas filling provides convenient and reliable operation.

[0103] Device Example 3:

[0104] like Figure 11 and Figure 12As shown, this invention provides a third embodiment of the forming apparatus for implementing the above-mentioned on-orbit composite forming method for tubular profiles in both ground and space. This forming apparatus is essentially the same as that in Embodiment 1, except that: the forming apparatus in this embodiment includes a machine base 1, on which a positioning mechanism 2 for positioning the flat material is provided, and a tube expansion mechanism 4 for extruding the flat material through the gap at the end of the flat material to expand and reshape it into the desired tubular profile. In this structure, the machine base 1 serves as the mounting base for the positioning mechanism 2 and the tube expansion mechanism 4. The tube expansion mechanism 4 directly extrudes the flat material through the gap at the end of the flat material to expand and reshape it into the desired tubular profile, resulting in a simple and reliable structure.

[0105] In this embodiment, the positioning mechanism 2 includes a positioning platform 21, on which a groove 211 for placing the flat material is provided. The groove 211 is used to place the flat material to form a positioning, which is then expanded by the subsequent tube expansion mechanism 4.

[0106] In this embodiment, the width of the groove 211 matches the width of the flat material, and the bottom of the groove 211 has an arc-shaped structure. This arc-shaped structure facilitates the reduction of the flat material into the required tubular profile during the bulging process.

[0107] In this embodiment, the tube expansion mechanism 4 includes a mounting platform 41, an expansion column 42, and a driving component 43. Both the mounting platform 41 and the driving component 43 are mounted on the machine base 1. The expansion column 42 is movably mounted on the mounting platform 41. The driving component 43 is connected to the expansion column 42 and drives the expansion column 42 to move on the mounting platform 41, squeezing it through the gap at the flat material's end to perform expansion and shape the flat material back into the desired tube profile. In this structure, the expansion column 42 passes through the mounting platform 41 and can move linearly along it. The driving component 43 drives the expansion column 42 to move, thereby squeezing the expansion column 42 through the gap at the flat material's end for expansion. Its structure is simple and reliable.

[0108] In this embodiment, the bulging column 42 is configured as a cone structure at one end near the flat material. The end of the cone structure facilitates rapid insertion from the gap at the port of the flat material for bulging.

[0109] Device Example 4:

[0110] like Figure 13 As shown, this invention provides a fourth embodiment of the forming apparatus for implementing the above-mentioned on-orbit composite forming method for tubular profiles in both ground and space. This forming apparatus is essentially the same as that in Embodiment 1, except that: the forming apparatus in this embodiment includes a machine base 1, on which multiple gantry frames 5 are mounted. Each gantry frame 5 is equipped with an extrusion mechanism 6 for extruding the narrow edges of the flat material to restore it to the desired tubular profile. In this structure, the machine base 1 serves as the mounting base for the gantry frames 5, and the gantry frames 5 serve as the mounting base for the extrusion mechanism 6. The extrusion mechanism 6 extrudes the narrow edges of the flat material to restore it to the desired tubular profile. This structure is simple and reliable.

[0111] In this embodiment, the extrusion mechanism 6 includes a pair of extrusion bars 61 for extruding the narrow edge of the flat material. An extrusion drive cylinder 62 is mounted on each extrusion bar 61 and is installed on a corresponding gantry frame 5. In this structure, the extrusion bars 61, driven by the extrusion drive cylinder 62, extrude the narrow edge of the flat material, causing the flat material to gradually revert to the desired tubular profile.

[0112] In this embodiment, the contact surface between the extrusion strip 61 and the flat material is set as an arc-shaped surface. The arc-shaped surface allows the narrow edge to gradually form an arc-shaped edge as it widens under extrusion pressure, ensuring the quality of the pipe profile restoration.

[0113] In this embodiment, a pair of shaping strips 7 are also included for shaping the wide edges of the flat material during extrusion. The upper shaping strip 7 is mounted on the corresponding gantry 5 via a lifting cylinder 71, and the lower shaping strip 7 is mounted on the machine base 1. In this structure, the upper and lower shaping strips 7 are used to shape the upper and lower wide edges of the flat material during bulging to ensure the quality of the pipe profile restoration.

[0114] In this embodiment, the contact surface between the shaping strip 7 and the flat material is set as an arc-shaped surface. Similarly, the arc-shaped surface allows the wide edge to gradually form an arc-shaped edge during shaping, ensuring the quality of the pipe profile restoration.

[0115] Device Example 5:

[0116] like Figure 14 and Figure 15 As shown, this invention provides a fifth embodiment of the forming apparatus for implementing the above-mentioned on-orbit composite forming method for tubular profiles in both ground and space. This forming apparatus is essentially the same as that in Embodiment 1, except that: the forming apparatus in this embodiment includes a machine base 1, on which multiple gantry frames 5 are mounted. A forming mechanism 8, extending into the flat material and stretching its wide edges to restore the flat material to the desired tubular profile, is installed on the gantry frames 5. A fixing mechanism 9, extending into the flat material and fixing it, is also installed on the machine base 1. In this structure, the machine base 1 serves as the mounting base for the gantry frames 5 and the fixing mechanism 9, and the gantry frames 5 serve as the mounting base for the forming mechanism 8. The flat material is fixed by the fixing mechanism 9, and the forming mechanism 8 extends into the flat material and stretches its wide edges to restore it to the desired tubular profile. This structure is simple and reliable.

[0117] In this embodiment, the forming mechanism 8 includes a forming drive cylinder 81 and a forming rod 82. The forming drive cylinder 81 is mounted on the gantry frame 5, and the forming rod 82 extends into the flat material and is detachably connected to the forming drive cylinder 81. In this structure, the forming rod 82 is first extended into the flat material, and then the forming rod 82 is connected to the forming drive cylinder 81. The forming drive cylinder 81 is activated to drive the forming rod 82 to form the wide side of the flat material. Its structure is simple and ingenious.

[0118] In this embodiment, the fixing mechanism 9 includes a fixing seat 91 and a fixing rod 92. The fixing seat 91 is mounted on the machine base 1, and the fixing rod 92 extends into the flat material and is detachably connected to the fixing seat 91. In this structure, the fixing rod 92 extends into the flat material and is connected to the fixing seat 91. When the forming rod 82 moves, the fixing rod 92 also forms a forming force on the other wide side of the flat material, ensuring rapid expansion and forming.
