Embodiment Construction

[0013] Now, the present invention will be described in further detail in conjunction with preferred embodiments.

[0014] The present invention is a head manufacturing process for a hyperbaric oxygen chamber of a nuclear submarine, comprising the following steps:

[0015] 1) Place a mat to prevent scratching the steel plate under the steel plate material, cut the steel plate material into discs;

[0016] 2) Weld the cut discs, after welding, the weld seam is polished on both sides to be flush with the steel plate, and the weld seam is polished on both sides;

[0017] 3) Pre-stamping the wafer;

[0018] 4) Clean the pre-stamped semi-finished wafers, heat evenly at a temperature of 750°C to 850°C for 15 minutes, and then start to rotate and pressurize for no more than 30 minutes to form a head;

[0019] 5) After the hot spinning in step 4) is completed, the surface of the head is cleaned and solution heat treatment is performed.

[0020] Appropriate protective measures should...

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...
