Description

technical field

[0001] The invention relates to the technical field of metal material processing and forming, in particular to a method and device for deep drawing and forming of revolving body parts. Background technique

[0002] Pressure vessels, as airtight equipment carrying a certain pressure, have strict requirements on airtightness and pressure resistance. Common pressure vessels include metal pressure vessels, non-metal pressure vessels, and metal-lined composite pressure vessels. The common structure of the metal-lined composite material pressure vessel is a thin-walled rotary body. The thick-walled small-volume structure in the thin-walled rotary body is mainly formed by integral machining of half parts and then welded. The thin-walled large-volume structure is mainly formed by spinning or A method of deep drawing and then welding.

[0003] Stainless steel has become a common material for metal linings due to its excellent corrosion resistance, high temperature ox...
