A kind of lightweight stainless steel vihicle roof technique camber beam is related to stainless steel vihicle carline design field comprising the roundlet segmental arc of two sides and the great circle segmental arc at middle part, roundlet segmental arc respectively with great circle segmental arc junction with great circle segmental arc it is tangent；The radius r of roundlet segmental arc is the former design size of camber beam roundlet segmental arc, and the radius of great circle segmental arc is R1, R1< R, R are the former design size of camber beam great circle segmental arc；The interior high H=h+7mm of camber beam, h are former design size high in camber beam；The inner width D=d-3mm, d of camber beam are the former design size of camber beam inner width；The center of circle O of roundlet segmental arc2Distance L=l-1.5mm, l to camber beam center line OA are the former design center of circle O of camber beam roundlet segmental arc1To the distance of camber beam center line OA.The camber beam of the utility model becomes smaller great circle segmental arc radius, and roundlet segmental arc radius remains unchanged, and increases high in roof, reduce roof inner width, so that the position advance reservation that camber beam welding deformation mostly occurs anti-deformation, and then camber beam is made to meet quality of production requirement.
Description
Technical field
The utility model relates to stainless steel vihicle carline design fields, and in particular to a kind of lightweight stainless steel
Vehicle roof technique camber beam.
Background technique
Currently, the stainless steel vihicle of domestic demand is mostly lightweight vehicle, light-weighted vehicle save vehicle manufacture at
Sheet and operation kinetic energy cost.As shown in Figure 1, the carline of lightweight vehicle include two sides radius be r roundlet segmental arc and
The radius at middle part is the great circle segmental arc of R, the roundlet segmental arcs of two sides respectively with the great circle segmental arc junction at middle part and orthodrome
Section is tangent；A height of h in camber beam, camber beam inner width are d, the center of circle O of camber beam roundlet segmental arc1Distance to camber beam center line OA is l.Vehicle
For top bow by being made with a thickness of the thin plate stainless steel part of 1mm, welding deformation is larger, in the past in stamped carline mold
In car body car roof skeleton tooling, carline positioning is designed according to former design size, and soldered roof often goes out
High h is reduced in existing roof, the quality problems of inner width d ultra-wide, and deck component production is caused to complete not meeting design requirement, serious shadow
The quality of production and manufacturing schedule are rung.
Utility model content
Life is seriously affected in order to solve existing carline due to welding deformation leads to greatly high reduction inner width ultra-wide in roof
The technical issues of yield and quality and manufacturing schedule, the utility model provide a kind of lightweight stainless steel vihicle roof technique camber beam.
The utility model technical solution adopted for solving the technical problem is as follows:
A kind of lightweight stainless steel vihicle roof technique camber beam comprising the roundlet segmental arc of two sides and the orthodrome at middle part
Section, the roundlet segmental arcs of two sides respectively with the great circle segmental arc junction at middle part with great circle segmental arc it is tangent；The radius r of roundlet segmental arc
For the former design size of camber beam roundlet segmental arc, the radius of great circle segmental arc is R1, R1< R, R are the former design ruler of camber beam great circle segmental arc
It is very little；The interior high H=h+7mm of camber beam, h are former design size high in camber beam；The inner width D=d-3mm, d of camber beam are camber beam inner width
Former design size；The center of circle O of roundlet segmental arc2Distance L=l-1.5mm, l to camber beam center line OA are camber beam roundlet segmental arc
Original design center of circle O1To the distance of camber beam center line OA.
The beneficial effects of the utility model are: the camber beam becomes smaller great circle segmental arc radius, roundlet segmental arc radius is remained unchanged,
Roof increases high in roof, reduce roof inner width, so that the position advance reservation that camber beam welding deformation mostly occurs anti-deformation,
And then camber beam is made to meet quality of production requirement.
The camber beam has succeeded to be tried out in roof formal dress technique vehicle project, is verified by actual production, roof group butt welding
It connects in rear roof high, inner width and meets designing quality requirement, thoroughly solving high in roof after roof welding reduces inner width ultra-wide
The technical issues of.
Detailed description of the invention
Fig. 1 is the original design structural schematic diagram of stainless steel vihicle roof technique camber beam.
Fig. 2 is the design structure schematic diagram of the utility model lightweight stainless steel vihicle roof technique camber beam.
Specific embodiment
The utility model is described in further details with reference to the accompanying drawings and examples.
As shown in Fig. 2, the lightweight stainless steel vihicle roof technique camber beam of the utility model includes the roundlet segmental arc of two sides
With the great circle segmental arc at middle part, the roundlet segmental arcs of two sides respectively with the great circle segmental arc junction at middle part with great circle segmental arc it is tangent；
The radius r of roundlet segmental arc is the former design size of camber beam roundlet segmental arc, and the radius of great circle segmental arc is R1, R1< R, R are camber beam great circle
The former design size of segmental arc；The interior high H=h+7mm of camber beam, h are former design size high in camber beam；The inner width D=d- of camber beam
3mm, d are the former design size of camber beam inner width；The center of circle O of roundlet segmental arc2To the distance L=l-1.5mm, l of camber beam center line OA
For the former design center of circle O of camber beam roundlet segmental arc1To the distance of camber beam center line OA.
Below by taking the carline of No. 6 lines of Beijing Metro as an example, each dimensional parameters after the completion of product manufacturing require difference
Be: great circle segmental arc radius R=10000mm, two sides roundlet segmental arc radius r=350mm, two sides roundlet segmental arc are respectively inscribed within great circle
Segmental arc, the center of circle O of roundlet segmental arc1To the distance l=986.4mm of the center line OA of great circle segmental arc, camber beam inner width d=
2515.2mm interior high h=179.3mm.It is respectively according to the parameter of structure design size of the utility model camber beam: interior high H=
186.3mm, camber beam vertex are vertically increased by original A point to B point；Inner width d=2512.2mm, distance L=984.9mm, roundlet
Segmental arc radius r=350mm is remained unchanged；Since two sides roundlet segmental arc is respectively inscribed within great circle segmental arc, and the vertex of great circle segmental arc
For B, by R is calculated1=8801.9mm.By verifying, No. 6 lines of Beijing Metro are designed according to the utility model structure size
Carline, after being welded, inner width and Nei Gao meet manufacture and require.
