[0036] The outer tube body 10 and the outer tube bottom 16 are welded by laser welding. The inner tube body 20 or the outer tube body is gourd-shaped. The outer tube bottom 16 is roughly cylindrical and is provided with a vacuum hole 160 connected to the vacuum layer 30, and a sealing material groove 162 located outside the vacuum hole 160 and containing a sealing material. The sealing material groove 162 is convexly arranged toward the inner tube bottom 24.

[0037] During processing, the outer tube body 10 is formed first, the inner tube processing piece 200 is initially formed, and then the soft material model 40 is set inside the outer tube body 10, the inner tube processing piece 200 is inserted into the inside of the soft material model 40, and the inner and outer tube mouths are welded to form the connecting part 14, and the welded inner and outer tube bodies and the soft material model 40 are put into the mold together. The inner tube body 20 expands outwards under the internal water pressure, and the outside is formed by the soft material model 40, the outer tube body 10 and the mold, so that the inner tube processing piece 200 forms the same shape as the soft material model 40, the outer tube body 10, and the mold, that is, a shape with convex ends and concave in the middle, thereby forming the inner tube body 20.

[0038] The outer tube body 10 is placed into the mold by a metal through tube, and the two ends are sealed. Pressurized water is pressed into the interior of the metal through tube from the lower end. The interior of the metal through tube expands outward under the pressure until it fits the mold, forming a shape with convex ends and a concave middle. The mold is separated left and right, and the outer tube body 10 is taken out of the mold. The mouth of the outer tube is then rotated and pressed into shape by a machine, and the bottom of the outer tube is then rotated and pressed into shape by a machine, and the bottom of the mouth is cut neatly.

[0039] The outer tube bottom 16 is formed by drawing a metal sheet, and the mouth is cut neatly.

[0040] The inner tube processing part 200 is placed into the mold by a metal through pipe, and the two ends are sealed. Water under pressure is pressed into the metal tube from the lower end. The inside of the metal tube expands outwards under pressure until it fits the shape of the mold. The mold is separated from left to right, and the inner tube processing part 200 is taken out of the mold. The mouth of the inner tube is then pressed and formed by a machine rotation, and the bottom of the inner tube is then pressed and formed by a machine rotation, and the bottom of the mouth is cut neatly. The inner tube transition bottom 204 is formed by drawing and forming a metal sheet, and the mouth is cut neatly.

[0041] The inner tube body is butted with the inner tube transition bottom 204 and then welded into one. The soft material model 40 is inserted into the outer tube from the lower part of the outer tube with a larger opening, and the mouth of the model is lower than the mouth of the outer tube, leaving a certain distance, and the model is close to the inner wall of the outer tube. The welded inner tube is inserted into the inner part of the outer tube and the model assembly from the lower part with a larger opening, and the inner tube and the outer tube mouth are welded at the interference fit flat mouth. The inner and outer tubes and the soft material model with the mouth welded are put into the mold together, and pressurized water is pressed into the mouth of the inner tube. The inner tube expands outwards under the action of the internal pressure water to fit the shape of the soft material model. The outer part of the soft material model is the outer tube body, and the outer layer is the mold, that is, the inner tube body expands outwards under the action of the internal pressure water. Under the action of the external pressure mold, the outer tube and the model, it fits into the concave and convex shape of the model. The mold is separated from left to right, and the inner and outer tube bodies after molding are taken out, and the soft material model is taken out from the bottom opening position respectively. In this way, the inner tube body has the same shape of convex at both ends and concave in the middle as the outer tube body, and then the outer tube body is butt-welded with the bottom of the outer tube. When the inner tube body is formed, the gap between the inner tube processing part 200 and the outer tube is filled with the mold to prevent the inner and outer tubes from contacting each other.
