Description
Technical field
The present invention relates to a kind of pressure vessel field, the manufacturing method of specifically a kind of skirt Basic annular plate.
Background technology
For a long time, vertical or tower pressure vessel skirt Basic annular plate is all evenly distributed with U-shaped breach, to install base
Plinth bolt, 1000~5000mm of Basic annular plate inside and outside circle diameter range, 10~60mm of plate thickness, U-shaped breach design requirement machinery add
Work surface roughness, 40~200mm of length, 20~100mm of width；After usual Basic annular plate uses sectionally smooth join, with basic spiral shell
The anchor slab of bolt（Alternatively referred to as model）And template closed assembly, draw hole line, with bore circular hole；Added again using machine or gas cutting reconditioning is gone
Except U-shaped breach remainder, gas cutting interplanar distance is uneven difficult with end slope, surface irregularity, polishing, and pressure is caused to be held
Device skirt Basic annular plate U-shaped breach roughness requirements are excessively high, manufacturing expense is high, surface quality is poor, design structure and manufacturing technology
Fall behind.
Invention content
The purpose of the present invention is to solve the above-mentioned problems of the prior art, and then provide a kind of skirt Basic annular plate
Manufacturing method, efficiently solve previous skirt Basic annular plate U-shaped breach design structure and manufacturing technology method be backward, manufacture
The problem of costly, poor product quality..
The purpose of the present invention is what is be achieved through the following technical solutions：
A kind of manufacturing method of skirt Basic annular plate, step are a, 1 full page blanking of Basic annular plate, and disposable numerical control gas cutting
Go out U-shaped breach, is with brill circular hole area on the inside of U-shaped breach, outside is not rounded porose area, and the inner arc of U-shaped breach 2 is a diameter of
60mm；B, it will be cut into the Basic annular plate 1 and model and template concentric closed assembly of U-shaped breach, the good Basic annular plate of gas cutting is folded
It is placed on the top；C, be subject to the U-shaped breach inner arc center of circle, U-shaped breach passed through using 60 drill bits of φ, lower section model or
With the brill 56 circular hole centers of circle φ and stroke nest in template；D, match and bore 56 circular holes of φ, then dismantle each plate of closed assembly.
Further, in step a, Basic annular plate is segmented blanking, and when blanking, disposable gas cutting went out U-shaped breach, was divided
Each section of also splicing groove of the cutting for welding, is ensured the tolerance of U-shaped breach morpheme size when splicing by setting-out, will divided
Each section is welded into complete Basic annular plate in a ring.
The beneficial effects of the invention are as follows：By using technical scheme of the present invention, product quality be improved significantly, manufacture
Expense is substantially reduced.Technology is novel, practical, advanced, reliable；Design structure and manufacturing technology are optimized, saves and draws hole
The manufacturing expenses such as line, Basic annular plate drilling and gas cutting reconditioning, and U notch quality is significantly improved, the more advanced conjunction of technique
Reason, production efficiency improve about 1/4, are suitble to the design of the bearing devices skirt Basic annular plates such as pressure vessel, nuclear energy equipment and manufacture enterprise
Industry application.
Description of the drawings
Fig. 1 is the structural diagram of the present invention.
Fig. 2 is the enlarged structure schematic diagram of the U-shaped notch of the present invention.
Specific implementation mode
Below in conjunction with attached drawing, the present invention is described in further detail：The present embodiment is being with technical solution of the present invention
Under the premise of implemented, give detailed embodiment, but protection scope of the present invention is not limited to following embodiments.
As depicted in figs. 1 and 2, a kind of manufacturing method of skirt Basic annular plate involved by the present embodiment, step be,
A, 1 full page blanking of Basic annular plate, and disposable numerical control gas cutting goes out U-shaped breach 2,2 inside of U-shaped breach is with brill circular hole area 4, outside
For not rounded porose area 5, and a diameter of 60mm of inner arc of U-shaped breach 2；B, the Basic annular plate 1 and sample of U-shaped breach 2 will be cut into
Plate and template concentric closed assembly, the good Basic annular plate 1 of gas cutting overlay the top；C, it is with the U-shaped breach inner arc center of circle
Standard passes through U-shaped breach using 60 drill bits of φ, with the brill 56 circular hole centers of circle φ and stroke nest on the model of lower section or template；D, it is aligned
Nest position is drawn with 56 circular holes of φ are bored, then dismantles each plate of closed assembly, ensures that the hole site that partition board is bored is corresponding.
In step a, for Basic annular plate 1 with 1/4 segmentation blanking, when blanking, disposable numerical control gas cutting went out U-shaped breach 2, was divided
Each section of also splicing groove 6 of the cutting for welding, ensure the tolerance of 2 morpheme size of U-shaped breach when splicing by setting-out, will
Each section is divided to be welded into complete Basic annular plate 1 in a ring.
All segmentation weld seams are along ring flat-plate circumference uniform distribution.
Cancel the 2 center of arc's circular diameter tolerance of U-shaped breach and 2 center of arc of adjacent U-shaped breach that existing design requires
Extremely away from tolerance（- 2 ,+2）；Or it is suitably amplified to（- 3 ,+3）, because the present invention is using 1 automatic gas cutting U-shaped breach of Basic annular plate,
The a diameter of 60mm of inner arc, to with 56 circular holes of φ model, template cooperation install because be with Basic annular plate 1
It is carried out on the basis of the U-shaped breach circular arc that numerical control gas cutting goes out with boring, 2 center of arc of adjacent U-shaped breach can suitably be amplified to away from tolerance
（- 3 ,+3）.
2 surface roughness of U-shaped breach is optimized for numerical control gas cutting surface 3, using numerical control gas cutting in blanking disposably by U-shaped
2 gas cutting of notch shapes, more smooth compared to the surface of manual cutting；
Setting-out inspection is carried out when splicing each section of ring flat-plate, ensures 2 center of arc's circular diameter tolerance of U-shaped breach and adjacent U-shaped breach 2
Center of arc is away from tolerance；
Anchor bolt circular hole with each part for boring closed assembly on the basis of the circular arc after numerical control gas cutting.
The foregoing is only a preferred embodiment of the present invention, these specific implementation modes are all based on the present invention
Different realization methods under general idea, and scope of protection of the present invention is not limited thereto, it is any to be familiar with the art
Technical staff in the technical scope disclosed by the present invention, the change or replacement that can be readily occurred in, should all cover the present invention
Within protection domain.Therefore, the scope of protection of the invention shall be subject to the scope of protection specified in the patent claim.
