Embodiment 1
[0057] The specific implementation of this embodiment is as follows:
[0058] Such as figure 1 As shown in -4, it is a half-section structural diagram and a left-view structural schematic diagram of the structure of the closing cylinder 100 provided in this embodiment. Specifically, the closing cylinder 100 is a thin-walled high-strength aluminum alloy cylinder structure with variable wall thickness, including The structure in which the radial dimension gradually increases from the mouth of the cylinder to the bottom of the cylinder forms the inner wall 106 of the cylinder and the outer wall 105 of the cylinder, and a gradually changing thickness 107 with a gradually enlarged wall thickness is formed between the inner wall 106 of the cylinder and the outer wall 105 of the cylinder; A small hole 104 can be provided through the bottom of the cylinder body and the inner cylinder cavity 101, that is, a small hole 104 is formed between the bottom of the inner cylinder 103 and the b...
Embodiment 2
[0067] The high-strength, toughness, corrosion-resistant heat treatment process for the variable-wall-thickness thin-wall aluminum alloy closing cylinder 100 provided in this embodiment includes the following steps:
[0068] Step A: Anti-deformation heat treatment tooling 200 design
[0069] According to the shape and size of the variable wall thickness thin-walled aluminum alloy closing cylinder 100, the anti-deformation heat treatment tool 200 is designed. The tooling is designed as a double-layer sieve plate structure, including an upper fixed plate 202 and a lower fixed plate 205. The distance between the two fixed plates is longer than the height of the closing cylinder 100. Three steel rods are used between the two fixed plates, namely Fixed rod 201 is welded and fixed. The lower fixed plate 205 is evenly distributed with inverted cone-shaped holes at the bottom of the fixed closing cylinder 100, that is, the inverted frustum-shaped holes, and the upper fixed plate 202 ...
Embodiment 3
[0105] This embodiment provides a variable-wall-thickness thin-wall aluminum alloy closing cylinder 100 high-strength corrosion-resistant heat treatment process and anti-deformation tooling, including the following steps:
[0106] The first step is the design of anti-deformation heat treatment tooling 200. The distance between the upper fixed plate 202 and the lower fixed plate 205 is 20mm higher than that of the variable-wall thin-walled high-strength aluminum alloy closing cylinder 100; the upper diameter 2041 of the inverted frustum-shaped hole of the lower fixed plate 205 is larger than the bottom diameter of the cylinder 1mm, the diameter of the lower opening 2042 is 1mm smaller than the diameter of the bottom of the cylinder; the diameter of the first through hole of the upper fixed plate 202 is the same as the inner diameter of the cylinder mouth; the diameter of the hollow T-shaped support pin 203 fixed rod 201 is 0.6 smaller than the first through hole mm; the inner d...
