Abstract
The invention discloses a processing and welding process of a large end socket, which comprises the following steps of (1) processing a flap mould; (2) stamping and forming the flaps; (3) manufacturing a welding groove of the petal, and assembling and welding; and after assembling and welding, making a smooth curve between the petal bus and the head vertex, manufacturing a processing die of the top circular plate according to the smooth curve, stamping the top circular plate under the processing die, processing a welding groove, and welding the top circular plate and the petals. The process has simple operation steps, can eliminate shape mutation near the splicing welding line, and the welded seal head is beautiful and has good stress.
Description
Technical field
The present invention relates to a kind of processing, pressurising welding field of metal, particularly a kind of processing welding technique of large-sized end enclosure.
Background technology
At present, because end socket is the crucial pressure-containing parts of pressure vessel, the quality of end socket directly affects the use of container, thus can not as traditional small-sized end socket, direct pressurising be welded for large-sized end enclosure, but the assembling splicing of merotomizing is welded.The traditional handicraft of traditional large-sized end enclosure is: 1, the drawing respectively of each limb and tip circle plate, and 2, each limb assembly welding is become the part of end socket, 3, the splicing welding joint between welding limb and the tip circle plate.The shape of tip circle plate stamping and forming and limb drawing are to coordinate mutually in traditional handicraft, but because each limb assembly welding is when becoming end socket a part of, weld heating and residual stress when making drawing discharge to some extent, produce in welding and the cooling procedure and expand with heat and contract with cold, cause welding deformation to be difficult to control, these factors have caused the change of limb shape, and then be easy to generate the shape sudden change near making the splicing welding joint of limb and tip circle plate, not only influence attractive in appearance, and the local stress of shape sudden change place is increased, do not possess the requirement of using plant equipment after the assembling, influence the use or the service life of end socket.
Summary of the invention
The present invention has overcome deficiency of the prior art, and the processing welding technique that a kind of operating procedure is simple, can eliminate near the large-sized end enclosure of the shape sudden change of splicing welding joint is provided.
In order to solve the problems of the technologies described above, the present invention is achieved by the following technical solutions:
A kind of processing welding technique of large-sized end enclosure may further comprise the steps:
(1) processing limb mould;
(2) limb drawing;
(3) make the bevel for welding of limb, and assemble welding;
Key is: smooth curve is made in described step (3) back between limb bus and end socket summit, according to the processing mold of smooth curve making tip circle plate, the drawing under processing mold of tip circle plate, processing bevel for welding, welding tip circle plate and limb.
The present invention is all right: the described smooth curve of doing between limb bus and end socket summit is rule at first the limb button being placed on the platform, mark the center line circle of groove between straight flange end, limb and the tip circle plate at inner surface, outside from the center line circle of groove between limb and the tip circle plate, increase radius and make concentric circles, concentric circles is done three at least; On same bus, measure each concentric circles then to distance between the flat surface, and measure at least four buses simultaneously, by at each bus on each concentric circles to the mean value of distance between the flat surface, the bus of doing 1: 1 amplifies sample, and makes the end socket summit on bus amplification sample; Amplify between sample and the end socket summit at bus at last and make smooth curve.The described processing mold of making the tip circle plate according to smooth curve for according to smooth curve and after considering springback capacity as the model of tip circle plate bus, and according to model processing tip circle board mold.
Compared with prior art, the invention has the beneficial effects as follows: this technology is after limb assembling welding is finished, employing is being made smooth curve between limb bus and end socket summit, make the processing mold of tip circle plate according to smooth curve, the tip circle plate under processing mold, can well eliminate after the drawing since in the weld heating process sudden change of the shape of limb cause inharmonious with it, thereby eliminated near limb and the tip circle plate splicing welding joint shape sudden change.

The specific embodiment
Below in conjunction with the accompanying drawing and the specific embodiment the present invention is described in further detail:
Showing end socket as Fig. 4 mainly is to be welded by limb 1 and 2 splicings of tip circle plate, and its concrete welding procedure is as follows:
Because the sodium-cooled fast reactor container is non-standard container, (1) at first we process limb 1 mould according to the specific requirement of sodium-cooled fast reactor container, and determine springback capacity by the engineer testing of limb 1 springback capacity, repair mould according to the springback capacity of determining again.(2) the bevel for welding between each limb 1 difference drawing (3) processing limb 1, carry out the part that each limb 1 assembling is welded into end socket, as shown in Figure 3.(4) part button of the end socket finished of assembling welding is placed on the platform and rules, mark the straight flange end at inner surface, the center line of groove circle between limb 1 and the tip circle plate 2, outside from the center line circle of groove between limb 1 and the tip circle plate 2, every increase 100mm radius is made a concentric circles, at least three concentric circles, on same bus, measure each concentric circles then to the distance between the flat surface, measure minimum four buses symmetrically, press at each bus on each concentric circles to the mean value of distance between the flat surface, the bus of doing 1: 1 amplifies sample, and makes the end socket summit on bus amplification sample.Between bus amplification sample and end socket summit, make smooth curve, proofread and correct smooth curve, and, as the model of tip circle plate 2 buses, process tip circle plate 2 moulds behind the consideration springback capacity according to model based on the smooth curve after proofreading and correct with the CAD mapping.Utilize tip circle plate 2 mould drawing tip circle plates 2 at last, the processing bevel for welding, assembling, the splicing welding joint between welding limb 1 and the tip circle plate 2 is finished the processing welding of whole end socket.
