Abstract
The utility model relates to a thin-walled spherical seal head with an extra-large diameter and without folded edges. The thin-walled spherical seal head comprises a tip circle, arc-shaped claws are sequentially welded on the outer side wall of the tip circle to form a first belt, and arc-shaped claws are sequentially welded on the outer side of the first belt to form a second belt. The thin-walled spherical seal head is subjected to cold press molding, a claw forming mode is adopted for the seal head with the extra-large diameter, a three-belt machining scheme is adopted due to limitation of lengths of steel plates, and accordingly the forming technique for the spherical seal head without the folded edges and with the extra-large outer diameter of phi 17596X8 and the like is implemented.
Description
Technical field
The utility model relates to the technology of spherical tank end socket processing in the metal manufacture field, is specifically related to a kind of super-large diameter thin-walled without flanging spherical tank end socket.
Background technology
The spherical tank end socket mostly is middle-size and small-size structure, adopt heat treatment and rotary pressure technology moulding, but because sheet material is thinner, all be a difficult problem for moulding, cutting, the group equity of major diameter spherical tank, at present also not for the machine-shaping technology without the super-large diameter thin-walled vessel head of flanging external diameter φ 17596 * 8.
Summary of the invention
The utility model in the prior art to without large problem such as flanging external diameter φ 17596 * 8 seal head molding difficulty such as spherical tank such as super-large diameter such as grade, provide a kind of super-large diameter thin-walled without flanging spherical tank end socket.
Technical scheme: a kind of super-large diameter thin-walled comprises tip circle without flanging spherical tank end socket, is welded with successively arc melon lobe at the tip circle lateral wall, forms the ground floor endless belt, is welded with successively arc melon lobe in the first endless belt outside, forms the second endless belt.
Described tip circle is spherical cap structure.
In the butt weld of each melon lobe of tip circle and ground floor endless belt, in ground floor endless belt and the butt weld of second layer endless belt, in the butt weld of adjacent each melon lobe, along being welded with brace panel with the butt seam vertical direction.
Model gap≤5mm before the butt welding of adjacent melon lobe.
Beneficial effect: 1, the utility model cold isostatic compaction moulding, adopt the molding mode of melon lobe for large diameter end socket, owing to the processing schemes of minutes three bands are taked in the restriction of steel plate length, thereby realized without flanging external diameter φ 17596 * 8 technology such as seal head molding such as spherical tank such as super-large diameter such as grade.
2, strictly control the model gap of every melon lobe, guarantee model gap≤5mm, make special-purpose cutting model and cutting tool, guarantee that product is indeformable when cutting.Group guarantees that to taking special-purpose group to frock the whole group of thin-walled vessel head is to moulding.
3 the utlity model has simple in structure, the easy advantage of processing, work efficiency is high, and is effective, is beneficial to very much promotion and implementation.
Description of drawings
Figure l is the utility model surface structure scheme drawing.
Number in the figure 1 is tip circle, and 2 is the ground floor endless belt, and 3 is second layer endless belt, and 4 is brace panel.
The specific embodiment
Embodiment one: referring to Fig. 1, a kind of super-large diameter thin-walled belongs to 17596 * 8 end sockets such as spherical tank such as super-large diameter such as grade without flanging external diameter φ without flanging spherical tank end socket.For large diameter end socket like this, adopted the molding mode of melon lobe.Comprise spherical cap structure tip circle 1, be welded with successively arc melon lobe at the tip circle lateral wall, form ground floor endless belt 2, be welded with successively arc melon lobe in the first endless belt outside, form the second endless belt 3; Between tip circle and melon lobe, on the lateral surface between the adjacent melon lobe, along being welded with brace panel 4 with the butt seam vertical direction.
For large diameter end socket, because sheet material is thinner, moulding, cutting, group equity all are difficult problems, and the utility model is piled up several melon lobes when compacting melon lobe and beaten a drum, the model gap of strict control melon lobe, the model gap≤5mm before the butt welding of adjacent melon lobe.Make melon lobe cutting anti-deformation tool during cutting, the control cutting deformation, group to the time we take group to supporting tool, finally finished the integral manufacturing of end socket.
Claims (4)
1. a super-large diameter thin-walled is characterized in that without flanging spherical tank end socket: comprise tip circle, be welded with successively arc melon lobe at the tip circle lateral wall, form the ground floor endless belt, be welded with successively arc melon lobe in the first endless belt outside, form the second endless belt.
2. super-large diameter thin-walled according to claim 1 is characterized in that without flanging spherical tank end socket: described tip circle is spherical cap structure.
3. super-large diameter thin-walled according to claim 1 is without flanging spherical tank end socket, it is characterized in that: in the butt weld of each melon lobe of tip circle and ground floor endless belt, in ground floor endless belt and the butt weld of second layer endless belt, in the butt weld of adjacent each melon lobe, along being welded with brace panel with the butt seam vertical direction.
4. super-large diameter thin-walled according to claim 1 is characterized in that without flanging spherical tank end socket: the model gap≤5mm before the butt welding of adjacent melon lobe.
