Brief description
Accompanying drawing is used to provide a further understanding of the present invention, and constitutes the part of description, with following tool
Body embodiment is used for explaining the present invention together, but is not construed as limiting the invention.
A kind of flow chart of specific embodiment of manufacture method of the u rib unit that Fig. 1 provides for the present invention；
The flow chart of the manufacture method another kind specific embodiment of the u rib unit that Fig. 2 provides for the present invention.
Specific embodiment
Below in conjunction with accompanying drawing, the specific embodiment of the present invention is described in detail.It should be appreciated that this place is retouched
The specific embodiment stated is merely to illustrate and explains the present invention, is not limited to the present invention.
Refer to Fig. 1 and Fig. 2, a kind of stream of specific embodiment of manufacture method of the u rib unit that Fig. 1 provides for the present invention
Cheng Tu；The flow chart of the manufacture method another kind specific embodiment of the u rib unit that Fig. 2 provides for the present invention.
In a kind of specific embodiment, the invention provides a kind of manufacture method of u rib unit, walk including following
Rapid:
Fixing base plate；
U rib is positioned on described base plate；
From the angle seam crossing between u rib and described base plate described in described u rib interior welds；
From the angle seam crossing between u rib and described base plate described in described u rib outside weldings.
The above-mentioned steps of this manufacture method can be launched simultaneously, successively carries out, and can assemble u rib, while welding u
Rib is it is also possible to carry out interior weldering and outside weld, outside weld is relatively interior to be welded with the delayed of a few minutes simultaneously.
This manufacture method not only completes assembling and the welding process of whole u rib and base plate in a station, can also be simultaneously
Assembled and welded, compared with the manufacture method needing multiple stations in prior art, substantially increased work efficiency；Simultaneously
Also eliminate tack weld in this manufacture method, decrease one procedure, both reduced manufacturing cost, eliminate by tack welding again
The potential safety hazard that the defect of seam causes, improves the welding quality of u rib unit, makes u rib and base plate define the higher u of steadiness
Rib unit.
In further embodiment, further include steps of during fixing base plate
Step s11, described base plate is placed on work platformses；
Step s12, is fixed to described base plate using fixing tool.
Secure a base plate on work platformses, then during assembling and welding u rib, base plate is all on work platformses
Remain stationary as, until u rib and base plate are welded into u rib unit, the whole of u rib and base plate just can be completed on this work platforms
Assembling and welding process, work platformses are the station manufacturing u rib unit.
Further in specific embodiment, further include steps of when u rib is positioned on base plate
Step s21, determines the relative position of described u rib and described base plate；
Step s22, applies, to described u rib, the relative position that certain pressure ensures described u rib and described base plate.
After fixing base plate, u rib is hung on base plate, u rib and base plate have certain position relationship, determine u rib and bottom
After the relative position of plate, certain pressure is applied to u rib, make u rib and base plate keep relative position constant it is ensured that u rib and base plate
It is accurately positioned.
In a kind of preferred embodiment, in step s21, further comprise following steps:
Step s211, described base plate is provided with the position line of described u rib；
Step s212 is so that alignd with the described position line in the base of described u rib.
In order to ensure being accurately positioned of u rib and base plate, the position line of u rib first can be arranged on base plate, can be in base plate
On precalculated position draw the position line of u rib.During assembling u rib, according to the position line on base plate, make base and this position of u rib
Line aligns.
In another kind of preferred embodiment, ensure the relative position of described u rib and described base plate in step s22
When, the fit-up gap of reserved 0-2mm.
When welding u rib and base plate, dissimilar and different-diameter welding wire can correspond to different fit-up gaps, specifically
Fit-up gap needs according to the setting of the practical situation of welding process, so that weld seam reaches optimal penetration degree it is ensured that weld seam
Quality.
Fit-up gap it is not necessary to, in actual production, during assembling, have certain gap.There is gap can increase molten
Depth thoroughly, but, burn-through can be caused in too big gap again, and therefore, gap can not be too big.
In above-mentioned each specific embodiment, when the interior welds of described u rib, the described corner connection seam of welding both sides simultaneously
Place.
There are between u rib and base plate two angle seam crossings, when u rib interior welds, the corner connection seam of both sides is carried out simultaneously
Welding, welding once just completes to the welding within u rib, and welding efficiency is higher.
In further embodiment, during the inside welding described u rib, adopt internal welding machine.
Internal welding machine include can inside u rib movement mobile platform, the setting welding gun of two on mobile platform, two welderings
The head of rifle is located at the both sides of mobile platform respectively, can be respectively welded the angle seam crossing of the internal both sides of u rib simultaneously.
In mobile platform moving process, two welding guns can weld to the angle seam crossing of the internal both sides of u rib simultaneously, moves
Moving platform movement once just can complete the welding to internal two side welds of u rib unit.
In welding process, welding gun is consistent with the distance of the angle seam crossing of u rib, with identical attitude and parameter to u rib and bottom
The angle seam crossing of plate is welded, and improves the uniformity of weld seam, it is to avoid the failure welding of weld seam, obtains preferably welding effect
Really, the fatigue resistance of u rib unit after raising is welded.
In above-mentioned each specific embodiment, welding manner adopts gas shielded arc welding or submerged-arc welding.
When u rib and base plate are welded, gas shielded arc welding can be adopted, it would however also be possible to employ submerged-arc welding.Gas shielded arc welding
Welding equipment and welding process fairly simple, the welding quality stable of submerged-arc welding, welding productivity be high, no arc light, flue dust be relatively
Few.
Specifically, suitable welding manner can be selected according to actual situation.
It is understood that the embodiment of above principle being intended to be merely illustrative of the present and the exemplary enforcement adopting
Mode, but the invention is not limited in this.For those skilled in the art, in the essence without departing from the present invention
In the case of god and essence, various modifications and improvement can be made, these modifications and improvement are also considered as protection scope of the present invention.
