Abstract
Description
Technical Field
[0001] This application relates to the field of aluminum profile structures, and in particular to a high-strength shaped aluminum profile and its processing technology. Background Technology
[0002] There are many applications for aluminum profiles. For example, aluminum profiles are used for connection and fixation, acting as connecting arms; aluminum profiles can be used for support, serving as aluminum profile slides to support slides; aluminum profiles can be used as door and window frames to fix transparent glass.
[0003] When aluminum profiles are used for support, their support height mainly depends on the cross-sectional height of the aluminum profile. The support height varies for different objects being supported, and it may even be necessary to make temporary adjustments to the support height based on the actual application scenario of the supported object. Generally, rigid shims are used as compensation for the support height. However, the rigid shims must be customized to accurately compensate for the support height. In other words, the non-adjustable support height of the aluminum profiles used for support will greatly reduce the applicable range of the supported objects.
[0004] Therefore, this application provides a high-strength shaped aluminum profile with adjustable cross-sectional dimensions to adapt to actual application scenarios, thereby expanding the application range of shaped aluminum profiles. Summary of the Invention
[0005] In order to achieve adjustable dimensions of aluminum profiles, this application provides a high-strength special-shaped aluminum profile and its processing technology.
[0006] This application provides a high-strength shaped aluminum profile, which adopts the following technical solution:
[0007] A high-strength shaped aluminum profile includes a core, two sets of limiting guide members, two sets of support members, two first adjustment components, and two second adjustment components. Each set of limiting guide members includes two symmetrically arranged guide members about the core axis. The four limiting guide members are evenly distributed around the core axis. Each limiting guide member has two first mating inclined surfaces. The first adjustment components are used to adjust and fix the radial position of the two limiting guide members in the same set relative to the core. Each set of support members includes two symmetrically arranged support members about the core axis. The support members are located within the circumferential gap between adjacent limiting guide members. The radial distance between the support member and the core is greater than the radial distance between the limiting guide member and the core. Each support member has two second mating inclined surfaces. The second mating inclined surfaces of the support members fit against the first mating inclined surfaces of adjacent limiting guide members, with the outer right-angled surface of the support member serving as the support surface. The second adjustment components are used to adjust and fix the radial position of the two support members in the same set relative to the core.
[0008] The above technical solution involves first determining the required cross-sectional dimensions and preset side lengths of the shaped aluminum profile based on the actual application scenario. Then, the radial distance between the limiting guide component and the core axis is calculated based on the preset side length of the aluminum profile. Next, the first adjustment component is used to adjust and fix the radial positions of the two limiting guide components relative to the core. After the limiting guide components are fixed, the second adjustment component is used to adjust the radial positions of the two support components relative to the core until the second mating inclined surface of the support component fits against the first mating inclined surface of the limiting guide component. Finally, the second adjustment component fixes the support component, completing the assembly of the shaped aluminum profile.
[0009] By setting up a core, a first adjustment component, a second adjustment component, a limiting force guide, and a support component, the core serves as the foundation, and the first and second adjustment components serve as the connecting structure, so that the limiting force guide and the support component can be adjusted and fixed separately. By adjusting the radial position of the limiting force guide and the support component, the cross-sectional dimensions of the overall irregular aluminum profile can be adjusted, thereby making adaptive adjustments according to the actual application scenario and thus improving the application range of the irregular aluminum profile.
[0010] Secondly, the first mating inclined surface of the limiting guide and the second mating inclined surface of the support are in contact, which can improve the mating rigidity between the two. When the shaped aluminum profile is compressed, the upper and lower support will apply vertical opposing pressure to the limiting guide located in the middle. This vertical opposing pressure is partially converted into two horizontally separated force components through the cooperation of the first and second mating inclined surfaces, so as to force the two horizontally arranged limiting guides to move away from each other. The first adjustment component, as the connecting structure between the core and the limiting guide, can transmit the two horizontally separated force components, so that the two horizontally separated force components cancel each other out, thereby indirectly improving the compressive strength of the shaped aluminum profile.
[0011] Optionally, one side of the support member can be designated as the mounting groove surface, and the mounting groove surfaces of two adjacent support members can be combined to form a mounting groove.
[0012] Optionally, the first adjustment assembly includes two first screws, which extend radially along the core. The first screws of the two first adjustment assemblies are staggered along the axial direction of the core. One end of the first screw is rotatably engaged with the limiting force guide, and the other end of the first screw is threadedly engaged with the core.
[0013] Optionally, the second adjustment assembly includes two second screws that extend radially along the core. The second screws of the two second adjustment assemblies are staggered along the axial direction of the core. One end of the second screw is rotatably engaged with the support member, and the other end of the second screw is threadedly engaged with the core.
[0014] Optionally, the inner wall of the limiting guide member is integrally formed with two first ribs, and one side of the first rib is integrally formed with a first one-way tooth. The limiting guide member is provided with multiple first punching slits, which divide the limiting guide member into an axially arranged first deformable section and a first fixed section. The first adjusting component includes two first elastic rods, which extend radially along the core. The first elastic rods of the two first adjusting components are arranged in a staggered manner along the axial direction of the core. One end of the first elastic rod is connected to the core, and the other end of the first elastic rod is provided with a second one-way tooth and a first clearance notch. The second one-way tooth meshes with the first one-way tooth. When the limiting guide member moves radially towards the core, the second one-way tooth and the first one-way tooth elastically clearance each other. When the limiting guide member moves radially away from the core, the second one-way tooth and the first one-way tooth mesh with each other to prevent the limiting guide member from moving. The displacement of the force guide component; the inner wall of the support component is integrally formed with two second ribs, and one side of the second rib is integrally formed with a third one-way tooth. The support component is provided with multiple second punching slits, which divide the support component into a second deformable section and a second fixed section arranged axially. The second adjustment component includes two second elastic rods, which extend radially along the core. The second elastic rods of the two second adjustment components are arranged in a staggered manner along the core. One end of the second elastic rod is connected to the core, and the other end of the second elastic rod is provided with a fourth one-way tooth and a second clearance notch. The fourth one-way tooth and the third one-way tooth mesh with each other. When the support component moves radially in the direction close to the core, the fourth one-way tooth and the third one-way tooth elastically avoid each other. When the support component moves radially in the direction away from the core, the fourth one-way tooth and the third one-way tooth mesh with each other to prevent the displacement of the support component.
[0015] Optionally, one side of the limiting guide member is provided with a first oblong hole extending along its own length, through which the first elastic rod passes; when the limiting guide member needs to move radially towards the core, the second one-way tooth of the first elastic rod engages with the first one-way tooth located in the first easily deformable section; when the limiting guide member has moved radially, the core moves axially relative to the limiting guide member, so that the second one-way tooth of the first elastic rod engages with the first one-way tooth located in the first fixed section; one side of the support member is provided with a second oblong hole extending along its own length, through which the second elastic rod passes; when the support member needs to move radially towards the core, the fourth one-way tooth of the second elastic rod engages with the third one-way tooth located in the second easily deformable section; when the support member has moved radially, the core moves axially relative to the support member, so that the fourth one-way tooth of the second elastic rod engages with the third one-way tooth located in the second fixed section.
[0016] Optionally, it also includes steel strands. The core is a hollow tube structure with multiple through holes running radially through it. The two first elastic rods of the first adjusting component are offset along the axial direction of the core, and the two second elastic rods of the second adjusting component are offset along the axial direction of the core. The ends of the first and second elastic rods are inserted into the through holes. Each end of the first and second elastic rods has a wire hole. The wire holes are located at different axial and circumferential positions within the core cavity. The steel strands pass through each wire hole sequentially along the axial direction of the core. Anchors are provided at both ends of the core. The anchors include anchor seats fixed to the ends of the core. The anchor seats have conical holes, and multiple clamping pieces are provided in the conical holes. The inner arc surfaces of the clamping pieces have protruding teeth, and each clamping piece is used to enclose and tighten the steel strands.
[0017] Optionally, the inner wall of the limiting force guide is integrally formed with a T-shaped first reinforcing rib, which supports the first screw; the inner wall of the support is integrally formed with a T-shaped second reinforcing rib, which supports the second screw.
[0018] This application provides a processing technology for high-strength shaped aluminum profiles, which adopts the following technical solution:
[0019] A processing technology for high-strength shaped aluminum profiles includes the following steps: S1, forming a limiting guide and a support; S2, assembling the shaped aluminum profile: installing a first screw on the limiting guide, engaging the other end of the first screw with the core, calculating the radial distance between the limiting guide and the core axis according to the preset side length of the aluminum profile, rotating the first screw, which drives the limiting guide to move radially toward the core until the position of the limiting guide is adjusted, then installing a second screw on the support, engaging the other end of the second screw with the core, rotating the second screw, which drives the support to move radially toward the core until the second mating inclined surface of the support fits against the first mating inclined surface of the limiting guide, thus completing the assembly of the shaped aluminum profile.
[0020] In summary, this application includes at least one of the following beneficial technical effects:

Detailed Implementation
[0035] The following is in conjunction with the appendix Figure 1 -Appendix Figure 12 This application will be described in further detail.
[0036] Example 1
[0037] Example 1 discloses a high-strength irregular-shaped aluminum profile, such as Figure 1 , Figure 2 , Figure 3 As shown, the high-strength shaped aluminum profile includes a core 1, two sets of limiting and guiding force components 2, two sets of supporting components 3, two first adjustment components and two second adjustment components, wherein the core 1 is a solid rod, and the axis of the core 1 is the axis of the shaped aluminum profile.
[0038] like Figure 2 , Figure 3 As shown, a set of limiting force guides 2 includes two limiting force guides 2 symmetrically arranged around the axis of the core 1. The limiting force guides 2 extend along the axial direction of the core 1. The two limiting force guides 2 in one set are horizontally symmetrical, and the two limiting force guides 2 in the other set are vertically symmetrical, so that the four limiting force guides 2 are evenly arranged around the axis of the core 1. The limiting force guides 2 have two first mating inclined surfaces 21. The shortest distance between the two first mating inclined surfaces 21 gradually increases in the radial direction away from the core 1.
[0039] like Figure 2 , Figure 3 , Figure 4As shown, the first adjustment component is used to adjust and fix the radial position of the two limiting guide members 2 in the same group relative to the core 1. The first adjustment component plays a connecting and fixing role. Therefore, in order to ensure the connection effect, the distribution position of the first adjustment component is optimized. The first adjustment component is distributed in three locations, respectively at both ends and the middle of the core 1. The first adjustment component includes two first screws 51, which extend radially along the core 1. The two first screws 51 in the same group are collinear, while the first screws 51 of two adjacent first adjustment components are staggered along the axial direction of the core 1.
[0040] One end of the first screw 51 is rotatably engaged with the limiting guide member 2, and the other end of the first screw 51 is threadedly engaged with the first threaded hole 511 that radially penetrates the core 1. Specifically, the limiting guide member 2 has a first through hole 22 through it on the side closer to the core 1, and a first recessed groove 23 is formed on the side of the limiting guide member 2 away from the core 1. The first screw 51 passes through the groove wall of the first recessed groove 23 and the first through hole 22 in sequence. The screw head of the first screw 51 is located in the first recessed groove 23. The first screw 51 is threaded with a first nut 512. The first nut 512 and the screw head of the first screw 51 are located on both sides of the groove wall of the first recessed groove 23, so that the first screw 51 and the limiting guide member 2 are axially limited and engaged.
[0041] Furthermore, the inner wall of the limiting guide component 2 is integrally formed with a T-shaped first reinforcing rib 24, which supports the first screw 51.
[0042] like Figure 2 , Figure 3 , Figure 4 As shown, the two sets of support members 3 include two support members 3 symmetrically arranged with the axis of the core 1. The support members 3 extend along the axial direction of the core 1. The support members 3 are located in the circumferential gap between two adjacent limiting force guide members 2. The radial distance between the support member 3 and the core 1 is greater than the radial distance between the limiting force guide member 2 and the core 1. The support member 3 has two second mating inclined surfaces 31. The shortest distance between the two second mating inclined surfaces 31 gradually increases in the radial direction away from the core 1. The second mating inclined surface 31 of the support member 3 is in contact with the first mating inclined surface 21 of the adjacent limiting force guide member 2.
[0043] The outer right-angled surface of the support member 3 is designated as the support surface 32, which serves as the outer surface of the irregular aluminum profile. Furthermore, one side of the support member 3 is designated as the mounting groove surface 33, and the mounting groove surfaces 33 of two adjacent support members 3 are combined to form a mounting groove, which is suitable for applications where glass edges of door and window frames are fitted together.
[0044] like Figure 2 , Figure 4As shown, the second adjustment assembly is used to adjust and fix the radial position of the two support members 3 in the same group relative to the core 1. The second adjustment assembly plays a connecting and fixing role. Therefore, in order to ensure the connection effect, the distribution position of the second adjustment assembly is optimized. The second adjustment assembly is distributed in three locations, located at both ends and the middle of the core 1. The second adjustment assembly includes two second screws 61, which extend radially along the core 1. The two second screws 61 in the same group are collinear, while the second screws 61 of adjacent second adjustment assemblies are staggered along the axial direction of the core 1.
[0045] like Figure 2 , Figure 3 As shown, one end of the second screw 61 is rotatably engaged with the support member 3, and the other end of the second screw 61 is threadedly engaged with the second threaded hole 611 that radially penetrates the core 1. Specifically, a second through hole 35 is provided on the side of the support member 3 near the core 1, and a second recessed groove 34 is formed on the side of the support member 3 away from the core 1. The second screw 61 passes through the groove wall of the second recessed groove 34 and the second through hole 35 in sequence. The screw head of the second screw 61 is located in the second recessed groove 34. A second nut 612 is threaded onto the second screw 61. The second nut 612 and the screw head of the second screw 61 are located on both sides of the groove wall of the second recessed groove 34, so that the second screw 61 and the support member 3 are axially limited and engaged.
[0046] Furthermore, the inner wall of the limiting guide component 2 is integrally formed with a T-shaped second reinforcing rib 36, which supports the second screw 61.
[0047] To improve strength, in other embodiments, the profile thickness of the limiting force guide 2 and the support 3 can be further increased.
[0048] Example 1 also discloses a processing technology for high-strength shaped aluminum profiles, including the following steps:
[0049] S1. Processing and forming of limiting force guide 2 and support 3: including the following steps: S11. Material inspection; S12. Heat treatment; S13. Extrusion forming of limiting force guide 2 and support 3; S14. Finished product sawing.
[0050] S2. Assembly of irregular aluminum profiles: Based on the actual application scenario, determine the cross-sectional dimensions and preset side lengths of the irregular aluminum profile to be adjusted. Install the first screw 51 on the limiting guide 2, and mate the other end of the first screw 51 with the core 1. Calculate the radial distance between the limiting guide 2 and the axis of the core 1 based on the preset side length of the aluminum profile. Rotate the first screw 51, which will cause the limiting guide 2 to move radially toward the core 1 until the position of the limiting guide 2 is adjusted. Then, install the second screw 61 on the support 3, and mate the other end of the second screw 61 with the core 1. Rotate the second screw 61, which will cause the support 3 to move radially toward the core 1 until the second mating inclined surface 31 of the support 3 fits against the first mating inclined surface 21 of the limiting guide 2, thus completing the assembly of the irregular aluminum profile.
[0051] The implementation principle of Example 1 is as follows: by setting up a core 1, a first adjustment component, a second adjustment component, a limiting force guide 2, and a support 3, the core 1 serves as the foundation, and the first and second adjustment components serve as the connecting structure, so as to adjust and fix the limiting force guide 2 and the support 3 respectively. By adjusting the radial position of the limiting force guide 2 and the support 3, the cross-sectional dimensions of the overall irregular aluminum profile can be adjusted, so as to make adaptive adjustments according to the actual application scenario, thereby improving the application range of the irregular aluminum profile.
[0052] Secondly, the first mating inclined surface 21 of the limiting guide member 2 and the second mating inclined surface 31 of the support member 3 are in contact with each other, which can improve the mating rigidity between the two. When the shaped aluminum profile is compressed, the upper and lower support members 3 will apply vertical opposing pressure to the limiting guide member 2 located in the middle. This vertical opposing pressure is partially converted into two horizontally separated force components through the cooperation of the first mating inclined surface 21 and the second mating inclined surface 31, so as to force the two horizontally arranged limiting guide members 2 to move away from each other. The first adjustment component, as the connecting structure between the core 1 and the limiting guide member 2, can transmit the two horizontally separated force components, so that the two horizontally separated force components cancel each other out, thereby indirectly improving the compressive strength of the shaped aluminum profile.
[0053] Example 2
[0054] The difference between Example 2 and Example 1 is that, as Figure 5 , Figure 6 As shown, the inner wall of the limiting force guide 2 is integrally formed with two first ribs 25. The first ribs 25 are inclinedly extended in the direction away from the core 1. One side of the first rib 25 is integrally formed with a first one-way tooth 251, and the tip of the first one-way tooth 251 faces the core 1.
[0055] like Figure 7As shown, the limiting force guide 2 is provided with multiple first punching slots 20. The first punching slots 20 penetrate the first mating inclined surface 21, the first rib plate 25 and the first one-way tooth 251. The first punching slots 20 divide the limiting force guide 2 into multiple first deformable segments 201 and multiple first fixed segments 202 arranged axially (the area between two adjacent first punching slots 20 is the first deformable segment 201, and the area between two adjacent first punching slots 20 is the first fixed segment 202).
[0056] like Figure 5 , Figure 6 , Figure 7 , Figure 8 As shown, the distribution position of the first adjustment component in this embodiment is consistent with that in Embodiment 1. The first adjustment component includes two first elastic rods 52. The first elastic rods 52 extend radially along the core 1. The two first elastic rods 52 in the same group are arranged collinearly. The first elastic rods 52 of the two first adjustment components are staggered along the axial direction of the core 1. One end of the first elastic rod 52 is fixedly connected to the core 1, such as by welding. One side of the limiting guide member 2 is provided with a first waist-shaped hole 203 extending along its own length direction. The first waist-shaped hole 203 allows the first elastic rod 52 to pass through. The other end of the first elastic rod 52 is provided with a second one-way tooth 521 and a first clearance notch 522. The two rows of second one-way teeth 521 are respectively located on both sides of the first elastic rod 52. The tips of the second one-way teeth 521 face away from the direction of the core 1. The first clearance notch 522 facilitates the elastic deformation of the two rows of second one-way teeth 521 towards each other.
[0057] The second one-way tooth 521 engages with the first one-way tooth 251.
[0058] like Figure 5 , Figure 9 As shown, the inner wall of the support member 3 is integrally formed with two second ribs 37. The second ribs 37 are inclinedly extended in the direction away from the core 1. A third one-way tooth 38 is integrally formed on one side of the second ribs 37, and the tip of the third one-way tooth 38 faces the core 1.
[0059] like Figure 10 As shown, the support member 3 is provided with multiple second punching slots 30. The second punching slots 30 penetrate the second mating inclined surface 31, the second rib plate 37 and the third one-way tooth 38. The second punching slots 30 divide the support member 3 into multiple second deformable sections 301 and multiple second fixed sections 302 arranged axially (the area between two adjacent second punching slots 30 is the second deformable section 301, and the area between two adjacent second punching slots 30 is the second fixed section 302).
[0060] like Figure 5 , Figure 9 , Figure 10As shown, the distribution position of the second adjustment component in this embodiment is consistent with that in Embodiment 1. The second adjustment component includes two second elastic rods 62, which extend radially along the core 1. The two second elastic rods 62 in the same group are arranged collinearly, and the second elastic rods 62 of adjacent second adjustment components are staggered along the axial direction of the core 1. One end of the second elastic rod 62 is fixedly connected to the core 1, such as by welding. One side of the support member 3 is provided with a second waist-shaped hole 303 extending along its own length direction, through which the second elastic rod 62 passes. The other end of the second elastic rod 62 is provided with a fourth one-way tooth 621 and a second clearance notch 622. The two rows of fourth one-way teeth 621 are located on both sides of the second elastic rod 62, with the tips of the fourth one-way teeth 621 facing away from the core 1. The second clearance notch 622 facilitates the elastic deformation of the two rows of fourth one-way teeth 621 towards each other.
[0061] The fourth unidirectional tooth 621 meshes with the third unidirectional tooth 38.
[0062] When assembling the irregular aluminum profile, the first elastic rod 52 passes through the first waist-shaped hole 203 of the limiting guide member 2, that is, the second one-way tooth 521 is located in the inner cavity of the limiting guide member 2. At this time, the first elastic rod 52 is located in the first deformable section 201 of the limiting guide member 2. Then the limiting guide member 2 moves radially in the direction close to the core 1. The second one-way tooth 521 of the first elastic rod 52 engages with the first one-way tooth 251 located in the first deformable section 201. The second one-way tooth 521 and the first one-way tooth 251 elastically avoid each other, that is, the limiting guide member 2 can move radially normally. After the limiting guide member 2 moves to the correct position, the second one-way tooth 521 of the first elastic rod 52 meshes with one of the first one-way teeth 251 located in the first deformable section 201.
[0063] Then, the support member 3 is installed. The second elastic rod 62 passes through the second oblong hole 303 of the support member 3, that is, the fourth one-way tooth 621 is located in the inner cavity of the support member 3. At this time, the second elastic rod 62 is located in the second deformable section 301 of the support member 3. Then, the support member 3 moves radially in the direction close to the core 1. The fourth one-way tooth 621 of the second elastic rod 62 engages with the third one-way tooth 38 located in the second deformable section 301. The fourth one-way tooth 621 and the third one-way tooth 38 elastically avoid each other, that is, the support member 3 can move radially normally. After the support member 3 moves to the correct position (the second mating inclined surface 31 is in contact with the first mating inclined surface 21), the fourth one-way tooth 621 of the second elastic rod 62 meshes with one of the third one-way teeth 38 located in the second deformable section 301.
[0064] Finally, the core 1 moves axially a certain distance relative to the support member 3 and the limiting guide member 2, so that the second one-way tooth 521 of the first elastic rod 52 engages with the first one-way tooth 251 located in the first fixed section 202, and the fourth one-way tooth 621 of the second elastic rod 62 engages with the third one-way tooth 38 located in the second fixed section 302.
[0065] The implementation principle of Example 2 is as follows: through the cooperation of the first one-way tooth 251 and the second one-way tooth 521, as well as the cooperation of the third one-way tooth 38 and the fourth one-way tooth 621, the radial position adjustment of the limiting guide member 2 and the support member 3 relative to the core 1 is more convenient, the overall installation steps are fewer, and it is convenient and quick.
[0066] Secondly, since the first one-way tooth 251, the second one-way tooth 521, the third one-way tooth 38, and the fourth one-way tooth 621 are all one-way teeth, the limiting guide 2 and the support 3 cannot radially detach from the core 1 after installation, thereby improving the overall structural stability. For example, when the limiting guide 2 is subjected to an external force and moves radially away from the core 1 (the external force can be lateral pressure), the second one-way tooth 521 and the first one-way tooth 251 mesh with each other to prevent the displacement of the limiting guide 2; when the support 3 is subjected to an external force and moves radially away from the core 1, the fourth one-way tooth 621 and the third one-way tooth 38 mesh with each other to prevent the displacement of the support 3. Furthermore, under the action of lateral pressure, due to the guiding force of the first mating inclined surface 21 and the second mating inclined surface 31, the limiting guide 2 will be forced to make slight displacement, resulting in a tighter meshing between the one-way teeth, thereby reducing the generation of mating gaps.
[0067] Example 3
[0068] The difference between Example 3 and Example 2 is that, as Figure 11 , Figure 12 As shown, the shaped aluminum profile also includes steel strands 7. The two first elastic rods 52 of the first adjusting component are offset along the axial direction of the core 1, and the two second elastic rods 62 of the second adjusting component are offset along the axial direction of the core 1, which is not the collinear arrangement in Embodiment 2.
[0069] The core 1 is a hollow tube structure, and multiple through holes 11 are radially penetrating the core 1. Each through hole 11 corresponds to a first elastic rod 52 and a second elastic rod 62, respectively.
[0070] The ends of the first elastic rod 52 and the second elastic rod 62 are both inserted into the through hole 11. Each end of the first elastic rod 52 and the second elastic rod 62 has a wire hole 53. Each wire hole 53 is located at a different axial position and a different circumferential position in the inner cavity of the core 1. The steel strand 7 passes through each wire hole 53 in sequence along the axial direction of the core 1.
[0071] Anchors are provided at both ends of the core 1. The anchors include anchor seats 71 fixed to the ends of the core 1. The anchor seats 71 have tapered holes 72. Multiple clamping pieces 73 are provided in the tapered holes 72. The inner arc surface of the clamping pieces 73 has protruding teeth. Each clamping piece 73 is used to enclose and tighten the steel strand 7.
[0072] Before assembling the irregular aluminum profile, the first elastic rod 52 and the second elastic rod 62 are respectively inserted into the corresponding through holes 11. At this time, the wire holes 53 of the first elastic rod 52 and the second elastic rod 62 are located in the inner cavity of the core 1. Then, the steel strand 7 is sequentially passed through the wire holes 53 of each first elastic rod 52 and each second elastic rod 62 along the axial direction of the core 1. Both ends of the steel strand 7 are located on the outside of the core 1. Then, the auxiliary tooling tube 10 is slid into the inner cavity of the core 1. The end of the auxiliary tooling tube 10 is pointed while the steel strand 7 is in a relaxed state. In this way, the pointed end of the auxiliary tooling tube 10 will push away the steel strand 7. At the same time, the steel strand 7 also needs to be... The steel strand 7 is arranged to avoid interference with the insertion of the auxiliary tooling tube 10. Then, the first elastic rod 52 and the second elastic rod 62 are ensured to abut against the outer circumferential surface of the auxiliary tooling tube 10. The auxiliary tooling tube 10 restricts the radial inward movement of the first elastic rod 52 and the second elastic rod 62. Then, the radially moving limiting guide member 2 and support member 3 are installed in place. Since the auxiliary tooling tube 10 restricts the radial inward movement of the first elastic rod 52 and the second elastic rod 62, the elastic force of the first one-way tooth 251 and the third one-way tooth 38 cannot force the first elastic rod 52 and the second elastic rod 62 to move radially inward, thus ensuring the normal installation of the limiting guide member 2 and the support member 3.
[0073] After the limiting guide 2 and the support 3 are radially installed in place, the auxiliary tooling tube 10 is removed. At this time, the first elastic rod 52 and the second elastic rod 62 have space to move radially inward. Then, anchor seats 71 are installed at both ends of the core 1. The steel strand 7 passes through the conical hole 72 of the anchor seat 71. Then, the steel strand 7 is tensioned by a hydraulic jack. The steel strand 7 is elastically stretched, and the steel strand 7 will drive the first elastic rod 52 and the second elastic rod 62 to move radially inward, so that the limiting guide 2 and the support 3 are more closely attached. Then, the end of the steel strand 7 is released. During the elastic retraction of the steel strand 7, the steel strand 7 will drive the clamp 73 to wedge more tightly into the conical hole 72. Multiple clamps 73 approach each other to tightly bite the steel strand 7, thereby preventing further elastic retraction of the steel strand 7 and fixing the steel strand 7, so that the steel strand 7 is in a taut state. Finally, the excess part of the steel strand 7 is cut off.
[0074] First, the elasticity of the steel strand 7 will serve as the internal stress of the shaped aluminum profile, thereby improving the rigidity and strength of the overall structure. Second, the steel strand 7 will drive the first elastic rod 52 and the second elastic rod 62 to move radially inward, which not only makes the limiting guide 2 and the support 3 fit together more closely, but also makes the meshing of each one-way tooth tighter, thereby reducing the generation of assembly gaps.
[0075] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
