Seal head manufacture process of nuclear submarine hyperbaric oxygen chamber

Abstract

The invention relates to a seal head manufacture process of a nuclear submarine hyperbaric oxygen chamber, comprising the following steps of: cutting, welding, pre-stamping, thermal spinning and thermal treatment. By adopting the process route of the invention to manufacture a seal head of the nuclear submarine hyperbaric oxygen chamber, a scratching phenomenon in a manufacturing process and a surface microcrack phenomenon generated during thermal processing can be effectively prevented, and the generation of defective products can be reduced; and in addition, the whole processing time of the seal head is shortened by 2 / 5, the cost is saved by 1-4, the energy resource is saved, the carbon emission amount is reduced directly or indirectly, and the dimensional control precision on the seal head is improved at the same time, therefore, the invention facilitates to fill in a gap on batch production of the seal heads in China under the premise of the foreign technopoly on manufacturing the seal head of the nuclear submarine hyperbaric oxygen chamber.

Description

technical field [0001] The invention relates to a head manufacturing process, in particular to a head manufacturing process for a nuclear submarine hyperbaric oxygen chamber. Background technique [0002] As a high-end military facility, nuclear submarines have pivotal strategic significance. The emergence and upgrading of Chinese nuclear submarines has enabled China's national power to rapidly increase. Because of the strategic position of nuclear submarines and the absolute need for safety, there are very strict control requirements for the overall manufacturing of nuclear submarines and the manufacture of their components. The hyperbaric oxygen chamber of the nuclear submarine provides life support for the submariners, which further reflects its importance. One of the most important components in the hyperbaric oxygen chamber of a nuclear submarine is the head, a component of the hyperbaric oxygen chamber. [0003] For these heads, the general processing method is hot s...

AI Technical Summary

Problems solved by technology

However, because it is a military facility, foreign countries are not open to related technologies. Domestic military enterprises adopt the processing method of hot stamping, which makes it difficult to control the dimensional accuracy requirements of the head, which also affects the surface quality of the head. The manufacturing cost is high and the manufacturing efficiency is low.
