Description
Technical field
The utility model relates to a kind of in light weight, wall thickness that is applied to aerospace field, erosion resisting the is seamless spherical tank of aluminum alloy.
Background technology
At present, be widely used in the tank in fields such as aerospace, most of for welding tank.Welding tank weld strength is low, stretch ratio is low, and surperficial conformability is poor, has potential safety hazard.What the now can be made seamless tank all is cylindricality basically, but cylindricality tank space availability ratio is low, Heavy Weight.
Summary of the invention
The utility model purpose provides a kind of in light weight, and space availability ratio is high, does not have stress concentration and distortion, stretch ratio height, the spherical tank of the seamless aluminum alloy that seamless surface is smooth.
The present invention realizes through following technical scheme: the spherical tank of a kind of seamless aluminum alloy; Comprise cylindrical shell; Cylindrical shell is spherical, on the two ends of same central axis of cylindrical shell, is respectively equipped with afterbody and case mouth II, and shoulder and case mouth I; Smooth seamless link between cylindrical shell, afterbody and the case mouth II, smooth seamless link between cylindrical shell, shoulder and the case mouth I.
The spherical tank of above-mentioned seamless aluminum alloy, described afterbody is processed round surface, and described shoulder is processed round surface.
The spherical tank of above-mentioned seamless aluminum alloy, case mouth I is provided with connecting thread and hermetically-sealed construction, and case mouth II is provided with butt flange.
The spherical tank of above-mentioned seamless aluminum alloy, cylindrical shell, afterbody, shoulder, case mouth I and case mouth II are 6061 aluminum alloy plate materials.
The manufacture craft of the utility model is: sheet material is through operation such as heat treatment → stretching → closing in → solid solution aging → fine limit work and the spherical tank of the formula that finally is integrally formed.Tank is by the plate stamping drawing and forming, and its inner chamber is guaranteed that by drawing die round surface is guaranteed by die face in the afterbody, and outer round surface of afterbody and mouth shape are guaranteed that by numerical control program round surface and mouth thickness guarantee by the closing in numerical control program in the shoulder.Tank shoulder and afterbody and spheroid turnover transitional region all adopt the design of wall thickness progressive additive, avoid producing stress concentration in the turnover transitional region, influence the overall performance of tank.
The beneficial effect of the utility model is: the utility model has been broken the unproductive record of the spherical tank of seamless aluminum alloy; Creatively selecting 6061 aluminum alloy plate materials with good plasticity, corrosion stability and cold-workability for use is raw material; Obtain tubular through punching stretch repeatedly; The closing in method obtains mouth on large-sized numerical control closing in machine, then the tank inwall is carried out anodic oxidation treatment, is the pressure container field provides a kind of in light weight, wall thickness, erosion resisting the is seamless spherical tank of aluminum alloy.The utility model is spherical, and the space availability ratio of tank is high.Owing to be structure as a whole, reduced welding sequence, also just reduced the weight of tank.Advantages such as the utility model is compared with welding technique, has in light weightly, wall thickness, does not exist stress concentration and distortion, stretch ratio high, and seamless surface is smooth, anticorrosive will be widely used in the aerospace field.
