A barrel-shaped laminated pressure-resistant device for deep-sea diving and its forming process

Abstract

The invention belongs to the technical field of deep-sea submersibles, and relates to a barrel-shaped laminated pressure-resistant device for deep-sea diving and its forming process. , the lower card slot cover, and the lower card plate cover are sequentially fastened by screws to form a closed barrel-shaped structure; through the non-mold inflatable method, multiple single-layer shells are turned into laminated shells; the invention uses a barrel-shaped structure to make The pressure-resistant shell has good load-bearing capacity. The laminated structure is used to reduce the design difficulty of the material, and the moldless forming method is adopted to reduce the manufacturing cost and improve the pressure-resistant capacity of the shell.

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. [0003] The current existing technology has the following defects: 1. The traditional pressure hull is a sing...

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
