Barrel-shaped laminated pressure-resistant device for deep sea diving and forming process thereof

Abstract

The invention belongs to the technical field of bathyscaphe, and relates to a barrel-shaped laminated pressure-resistant device for deep sea diving and a forming process of the barrel-shaped laminatedpressure-resistant device. The device is a closed barrel-shaped structure formed by fastening an upper end cover cap, an upper end connecting cover, an upper end clamping groove cover, a barrel-shaped laminated pressure-resistant shell, a lower end clamping groove cover and a lower end clamping plate cover in sequence; and the plurality of single-layer shells are made into a laminated shell through a die-free internal pressure bulging method. The barrel-shaped structure is adopted, so that the pressure-resistant shell has the good bearing capacity, the design difficulty of materials is reduced by adopting a laminated structure, the manufacturing cost is reduced by adopting a die-free forming method, and the pressure resistance of the shell is improved.

Description

technical field [0001] The invention belongs to the technical field of deep-sea submersibles, and relates to a deep-sea submersible pressure-resistant device and a forming method, more specifically, to a barrel-shaped laminated pressure-resistant device for deep-sea diving and a forming process thereof. Background technique [0002] Ocean engineering equipment is an important basis for human development, utilization and protection of the ocean, and it is also an important part of my country's strategic emerging industries and high-end equipment manufacturing. Submersibles are very important equipment in ocean exploration and deep sea research, and play a pivotal role. The pressure shell is an important part of the submersible, and the pressure shell can ensure the safety of the internal equipment and the safety of the staff during the submersion of the submersible.

AI Technical Summary

Problems solved by technology

[0003] At present, the existing technology has the following defects: 1. The traditional pressure hull is a single-layer structure, and the material design needs to meet the mechanical and service requirements at the same time. The design is difficult, the mechanical properties of the material are not fully utilized, and the internal stress cannot be effectively released during work, resulting in Decreased carrying capacity

2. The traditional processing method is: molding, the outer contour surface is mostly melon petal or arc surface

During welding, the welding residual stress is large, it is not easy to penetrate, and the forming accuracy is low

In the process of compression molding, the mold opening cost is high, the cycle is long, the manufacturing difficulty is high, and the surface quality is low
