Description
Technical field
The utility model relates to a kind of fuel tank, especially relates to the full aluminium fuel tank that a kind of automobile is used.
Background technique
In the production of the full aluminium fuel tank of automobile, the height of fuel tank leak-down rate be once welded into power, be two important indicators weighing fuel tank quality of product.The leakage of fuel tank often occurs in tank body of oil tank and end cap of gasoline tank welding interlock shaping place, fuel tank interlock is shaped and is often counted as one critical process in fuel tank production technology, reason is usually repeatedly searched in this procedure by manufacturer, but this procedure of flange of casing is not often caused attention before fuel tank interlock is shaped, the uniformity of the flatness after casing flange and the surrounding size after flange, often finally also affects the quality after interlock is shaped.
At present, fuel tank productive estabilishment enterprise often adopts the casing of whole flange, and the main body (not welding both sides end cap) of full aluminium fuel tank, is used material 3003, material thickness t=2mm as shown in Figure 1.Generally, the bending by global formation of this class fuel tank is become.As shown in Figure 2, the use one monoblock complete material of cutting is basis, and after the mounting hole that other parts of the complete assembling of subpunch need in advance, according to theoretical folding line position, sheet material is carried out to whole flange bending, after flange finishes, 9 side welds is stitched and is completed whole fuel tank.Way although it is so seems to be easy to realize, but, there is a lot of uncertain factors in it, job costs increase, the own Extendible Extent of working efficiency reduction and bending position and material is slightly different, the a thousand li that last shaping position will differ from, directly affects welding processing, increases the scrappage of product.Therefore,, in order to make the maintenance of welding quality stable and the surface smoothness of fuel tank, to the flange bending structure of fuel tank, improve very necessary.
Model utility content
The purpose of this utility model is exactly to provide a kind of full aluminium fuel tank in order to overcome the defect of above-mentioned prior art existence.
The purpose of this utility model can be achieved through the following technical solutions: a kind of full aluminium fuel tank, and described fuel tank is rectangle, it is characterized in that, comprises upper box and lower box, described upper box is connected with lower box coupling.
Described upper box comprises cover plate and lower hem, the seamless link vertical with lower hem of described cover plate, and described cover plate is provided with mounting hole.
Described lower box comprises base plate and upper hem, the seamless link vertical with upper hem of described base plate.
Described upper box is U-shaped that Open Side Down, and what described lower box was opening upwards is U-shaped.
Described cover plate and lower hem joint rounding off.
Described base plate and upper hem joint rounding off.
It is synthetic that the utility model changes traditional whole flange into two-part sample split welding, and two ends end cap is directly considered in the welding process of global formation, do not need the later stage to be welded with again end cap part, also in course of working, incorporated mould location, reliability and the serious forgiveness of product bending have been increased, reduce weld length, guaranteed mounting hole relative position, can complete bending and the weld task of tank body of oil tank high-efficiency high-quality.
Compared with prior art, the utility model overall construction design is reasonable, designs simplification, and working efficiency improves, dimensional uniformity is good, be adapted to produce in enormous quantities, and machining accuracy is high, quality of processing is stable, and weld seam is reduced to 8 from 9 of traditional scheme, has reduced and has welded failed risk.

Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is elaborated.
As shown in Figure 3-4, a kind of full aluminium fuel tank, described fuel tank is rectangle, it is characterized in that, comprises upper box 1 and lower box 2, described upper box 1 is connected with lower box 2 couplings.Described upper box 1 comprises cover plate 11 and lower hem 12, described cover plate 11 and the vertical seamless link of lower hem 12, joint rounding off.On described cover plate, 11 are provided with mounting hole.Described lower box 2 comprises base plate 21 and upper hem 22, described base plate 21 and the vertical seamless link of upper hem 22, joint rounding off.Described upper box 1 is U-shaped that Open Side Down, and what described lower box 2 was opening upwards is U-shaped.
The utility model is first according to the independent cutting upper box 1 of volume of fuel tank and the required sheet material of lower box 2; Then to the complete sheet material of cutting, use flanging die to substitute traditional bender and sheet material is carried out to flange, make the cover plate 11 of upper box 1 vertical with lower hem 12, the base plate 21 of lower box 2 is vertical with upper hem 22; After bending flange, on the part of moulding, on cover plate 11, adopt mould punching mounting hole; Finally upper box 1 is connected with lower box 2 weld seams, completes the making of whole full aluminium fuel tank.
Adopt flanging die carry out flange can guarantee the upper hem at upper box two ends and the bending position of the lower hem at lower box two ends definitely consistent, and even the specific elongation of material itself changes and also can make up error by post-production, and use mould greatly to accelerate process time, thereby fundamentally accelerated manufacturing efficiency, improved quality of product.Equally, use mould punching mounting hole, guaranteed the absolute position on fuel tank surface correct of each mounting hole.
Compared with prior art, the utility model has novelty, advance and usability in the designing for manufacturing of full aluminium fuel tank, sheet metal global formation is processed to have to promote the use widely value simultaneously.
