Abstract
The invention discloses an aluminium alloy seamless liner applied in the field of pressure vessel. The barrel of the aluminium alloy seamless liner is circular, the tail part thereof is an elliptical curved surface, the shoulder thereof is an elliptical curved surface, the bottle neck thereof is on the central axis of the liner barrel and is seamlessly and smoothly connected with the elliptical curved surface shoulder, and the bottle neck is provided with a connected screw thread and a sealing structure. The production technology of the aluminium alloy seamless liner is as follows: the barrel of the liner and the inner elliptical curved surface of the tail part are shaped by stamping and stretching, and the liner shoulder and the bottle neck are formed by that a tubular part is subjected to positive rotation closing and derotation closing; the blank of the liner is a 6061 aluminium alloy panel; and after the liner is shaped by spinning closing, solid solution and manual aging heat treatment are carried out, the inner surface of the liner is subjected to anode oxidation treatment so as to improve the anti-corrosion capability. The invention has large volume, high strength, strong anti-corrosion capability, seamless and smooth surface and good consistency.
Description
Technical field:
The present invention relates to a kind of big external diameter in pressurized container field, big volume, high strength and seamless inner bag of anticorrosion aluminium and production technology thereof of being applied to.
Background technique:
At present, be widely used in the inner bag of industries such as fire-fighting, mine, chemical industry, metallurgy, oil, electric power, medical treatment, explosion-proof, Aero-Space, most ofly be welding or little external diameter, little volume, inner bag that anti-corrosion capacity is low.Though welding inner bag external diameter is big, volume is big, weld strength is low, specific elongation is low, and surperficial conformity is poor.What the now can be made seamless inner bag all is little external diameter, little volume seal container basically, the seamless inner bag or the blank out of big external diameter, big volume.Trace it to its cause, big external diameter, the big seamless inner bag complex manufacturing of volume, the cylindrical member moulding is its bottleneck that is difficult to realize with closing up.If the inner bag internal surface does not improve the processing of anti-corrosion capacity, so in use, if the source of the gas poor quality will cause inner bag that the danger that is corroded is arranged, corrosion will badly influence the safe operation and the working life of container.Therefore, developing a kind of aluminium alloy seamless inner bag and production technology thereof is the new problem that needs to be resolved hurrily.
Summary of the invention:
The purpose of this invention is to provide a kind of aluminium alloy seamless inner bag and production technology thereof, this inner bag volume is big, the intensity height, and anti-corrosion capacity is strong after the internal surface anodizing, and seamless surface is smooth, high conformity.
The object of the present invention is achieved like this: a kind of band mounting structure gas cylinder, whole device is made up of cylinder valve, counter flange dish, gas cylinder, and the hard-wired counter flange dish that can be used for gas cylinder is set between gas cylinder and cylinder valve.
Main points of the present invention are its structure and working principle.Its working principle is: inner bag is by the plate stamping drawing and forming, its internal diameter is guaranteed by drawing die, oval calotte is guaranteed by die face in the afterbody, and the outer oval calotte of afterbody is guaranteed that by numerical control program inside and outside oval calotte of shoulder and mouth thickness guarantee by the closing in numerical control program.Inner bag shoulder and afterbody and cylindrical shell turnover transition region all adopt the design of wall thickness progressive additive, avoid producing stress in the turnover transition region and concentrate, and influence the overall performance of pressurized container.The invention has the advantages that and broken through big external diameter, the production difficult point of the big seamless inner bag of volume, creatively select for use and have good plasticity, 6061 aluminum alloy plate materials of corrosion resistance and cold-workability are raw material, obtain cylindrical member through punching stretch repeatedly, on large-sized numerical control closing in machine earlier with dextrorotation closing in method undergauge to certain diameter, obtain mouth with derotation closing in method again, solved the difficult problem that the major diameter cylindrical member could not close up or produce the mouth crackle, then the inner bag inwall is carried out anodizing, for the pressurized container field provides a kind of big volume, corrosion-resistant, smooth seamless aluminum alloy inner bag.
Aluminium alloy seamless inner bag and production technology thereof compared with prior art, it is big to have a volume, the intensity height, anti-corrosion capacity is strong, seamless surface is smooth, advantages such as high conformity will be widely used in the pressurized container field.
Description of drawings:
The present invention is described in detail below in conjunction with accompanying drawing and example.
Fig. 1 is a structural representation of the present invention.
With reference to accompanying drawing, a kind of aluminium alloy seamless inner bag, the cylindrical shell 1 of aluminium alloy seamless inner bag are circular, afterbody 2 is an oval calotte, shoulder 3 is an oval calotte, bottle neck 4 on inner bag cylindrical shell central axis and with the 3 smooth seamless links of oval calotte shoulder, there are connecting thread and sealing configuration in bottle neck 4 places; The production technology of aluminium alloy seamless inner bag is, oval calottes are through punching stretch forming in the cylindrical shell 1 of inner bag and the afterbody 2, and inner bag shoulder 3 and bottle neck 4 are closed up through dextrorotation+derotation by cylindrical member and make; The blank of inner bag is 6061 aluminum alloy plate materials; Carry out solid solution+artificial aging heat treatment after the moulding of interior gallbladder channel spinning closing-in, the internal surface of inner bag improves anti-corrosion capacity through anodizing.
Claims (4)
