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
The present invention relates to a kind of end socket manufacturing process, especially a kind of end socket manufacturing process of nuclear submarine hyperbaric oxygen chamber.
Background technology
Nuclear submarine has its very important strategic importance as high-end military installations, and the appearance of Chinese nuclear submarine and upgrading make the national power of China be able to fast lifting.Just because of the strategic position of nuclear submarine and to the absolute demand of safety has this very strict control requirement for the integral body manufacturing of nuclear submarine and the manufacturing of parts thereof.The hyperbaric oxygen chamber of nuclear submarine makes more that again for submarine person provides life support its importance is embodied.And the most always one of parts are exactly the part of hyperbaric oxygen chamber---end socket in the hyperbaric oxygen chamber of nuclear submarine.
For these end sockets, the general processing method that adopts is drop stamping, does suitable heat treatment then, but end socket dimensional accuracy, surface quality, inherent quality of materials are all had very high requirement, because the end socket wall thickness is all thicker, the equipment of making end socket is also needed corresponding ability.The specification of general end socket is EHA2540*44 or EHA2740*44, and its material is an austenitic stainless steel.But owing to be military installations, all open to correlation technique abroad, domestic military enterprise adopts the processing method of drop stamping, is difficult to control well the dimension precision requirement of end socket, and is also influential to the end socket surface quality, the manufacturing cost height, and it is low to make efficient.
Summary of the invention
The technical problem to be solved in the present invention is: a kind of production efficiency that can improve end socket is proposed, and the end socket manufacturing process of lower-cost nuclear submarine hyperbaric oxygen chamber.
The technical solution adopted in the present invention is: a kind of end socket manufacturing process of nuclear submarine hyperbaric oxygen chamber may further comprise the steps:
1) under steel plate materials, places the underbed that prevents to scratch steel plate, steel plate materials is cut, cut into disk;
2) disk with well cutting welds, and the two-sided polishing of welding back weld seam flushes with steel plate, and the butt welded seam twin polishing;
3) disk is carried out pre-punching;
4) pre-punching is good semi-finished product disk cleans up, and thermally equivalent begins rotation pressurization and is no more than 30 minutes and forms end socket after 15 minutes under 750 ℃～850 ℃ temperature;
5) after etc. the hot spinning in the step 4) is finished, end socket is carried out carrying out solution heat treatment after the surface clean.
Further specifically, the solid solubility temperature of the solution heat treatment in the step 5) of the present invention is 1060 ℃, and solution time is 60 minutes.
The invention has the beneficial effects as follows: adopt process route of the present invention, the end socket of making the nuclear submarine hyperbaric oxygen chamber can effectively prevent to scratch phenomenon in the manufacture process, and effectively prevents to occur in the hot-working crizzle phenomenon, reduces the generation of defective products; And shorten 2/5 the process time that can make whole end socket, cost savings 1/4, reduce the generation of defective products, energy savings, directly or indirectly reduce the carbon emission amount, improved size Control precision simultaneously, filled up abroad the blank that domestic batch process under the precondition of the technical monopoly of the end socket of making the nuclear submarine hyperbaric oxygen chamber is made end socket.
The specific embodiment
The present invention is further detailed explanation in conjunction with the preferred embodiments now.
The present invention is a kind of end socket manufacturing process of nuclear submarine hyperbaric oxygen chamber, may further comprise the steps:
1) under steel plate materials, places the underbed that prevents to scratch steel plate, steel plate materials is cut, cut into disk;
2) disk with well cutting welds, and the two-sided polishing of welding back weld seam flushes with steel plate, and the butt welded seam twin polishing;
3) disk is carried out pre-punching;
4) pre-punching is good semi-finished product disk cleans up, and thermally equivalent begins rotation pressurization and is no more than 30 minutes and forms end socket after 15 minutes under 750 ℃～850 ℃ temperature;
5) after etc. the hot spinning in the step 4) is finished, end socket is carried out carrying out solution heat treatment after the surface clean.
Need adopt suitable safeguard procedures during cutting, prevent that material from scratching in cutting process.Therefore below steel plate, place and prevent the underbed that scratches.
Described step 2) in the blanking scope of the two-sided 0.8cm of disk is carried out radioactivity polishing outward, with prevent and reduce end socket in spinning process scuffing and the material that causes because material surface is coarse ftracture.
Just the specific embodiment of the present invention of describing in the above specification, various not illustrating is construed as limiting flesh and blood of the present invention, the person of an ordinary skill in the technical field after having read specification can to before the described specific embodiment make an amendment or be out of shape, and do not deviate from essence of an invention and scope.
Claims (2)
1. the end socket manufacturing process of a nuclear submarine hyperbaric oxygen chamber is characterized in that may further comprise the steps:
1) under steel plate materials, places the underbed that prevents to scratch steel plate, steel plate materials is cut, cut into disk;
2) disk with well cutting welds, and the two-sided polishing of welding back weld seam flushes with steel plate, and the butt welded seam twin polishing;
3) disk is carried out pre-punching;
4) pre-punching is good semi-finished product disk cleans up, and thermally equivalent begins rotation pressurization and is no more than 30 minutes and forms end socket after 15 minutes under 750 ℃～850 ℃ temperature;
5) after etc. the hot spinning in the step 4) is finished, end socket is carried out carrying out solution heat treatment after the surface clean.
2. the end socket manufacturing process of nuclear submarine hyperbaric oxygen chamber as claimed in claim 1 is characterized in that: the solid solubility temperature of the solution heat treatment in the described step 5) is 1060 ℃, and solution time is 60 minutes.
