Embodiment 1
[0057] figure 1 As shown, it is a preferred embodiment provided by the present application. In this embodiment, it includes four body helical layers stacked in sequence, namely the first body helical layer 1, the second body helical layer 2, and the second body helical layer. The diameters of the three body helices 3 and the fourth body helices 4, the first body helices 1, the second body helices 2, the third body helices 3 and the fourth body helices 4 gradually decrease toward the central axis, At the same time, the column walls of the first somatic layer 1, the second somatic helical layer 2, the third somatic helical layer 3 and the fourth somatic helical layer 4 are all concave-convex and wavy;
[0058] From Figure 3-Figure 4 It can be seen that when the body helical layer is not bulging, it is a cylindrical structure. When it is bulging, the column wall of the body helical layer bends to form a wave shape, and the increase in the axial bending degree leads to local cur...
Embodiment 2
[0064] It can be seen from Example 1 that the present application not only has a relatively large improvement in structure, but also has unique features in the manufacturing process. Specifically, the manufacturing process in Example 1 is specifically described. figure 2 For the overall flow chart of the manufacturing process,
[0065] Step 1: Assemble the first body helix 1, place the first helical reinforcing tube 5 inside the first body helix 1, and cling to the inner wall of the first body helix 1, at this time the first body helix 1 is Cylindrical structure, the contact between the first helical reinforcing tube 5 and the first body helical layer 1 is fixed by welding. When welding, spot welding is used for positioning first, and then seam welding is used for fixing. The first helical reinforcing tube 5 and the first The body spiral layer 1 forms a weld 8 shown in 3a near the weld; image 3 The shown 3b is a schematic diagram of the structure manufactured according to t...
