Fig. 1 is the structural representation of rolling stock aluminum skirtboard embodiment of the present invention；
Fig. 2 is the structural representation of aluminium sheet in rolling stock aluminum skirtboard embodiment of the present invention.
Detailed description of the invention
For making the purpose of the embodiment of the present invention, technical scheme and advantage clearer, below in conjunction with the accompanying drawing in the embodiment of the present invention, technical scheme in the embodiment of the present invention is clearly and completely described, obviously, described embodiment is a part of embodiment of the present invention rather than whole embodiments.Based on the embodiment in the present invention, the every other embodiment that those of ordinary skill in the art are obtained under not making creative work premise, broadly fall into the scope of protection of the invention.
As Figure 1-Figure 2, the present embodiment rolling stock aluminum skirtboard, including aluminium sheet 1 and aluminum section frame 2, aluminium sheet 1 and aluminum section frame 2 spot welded together, also including filter 3, aluminium sheet 1 offers vent 11, the surrounding of vent 11 is fixed with rivet joint screw 4, filter 3 is fixed on rivet joint screw 4 and shelters from vent 11, and the outer surface of aluminium sheet 1 is also coated with skin of paint (not shown).
Specifically, vent 11 is offered on aluminium sheet 1 in the present embodiment rolling stock aluminum skirtboard, and it is provided around rivet joint screw 4 at vent 11, carry out Fixed-Filter 3 is installed by rivet joint screw 4, rivet joint screw 4 is riveted on aluminium sheet 1, the flatness of aluminium sheet 1 is affected less, it is possible to achieve on the premise of meeting aluminium sheet 1 flatness, aluminium sheet 1 is installed filter 3 and is aerated.Wherein, the surrounding of aluminium sheet 1 is additionally provided with seal washer (not shown).Concrete, after the present embodiment rolling stock aluminum skirtboard is installed on the car body of rolling stock, seal washer i.e. can play the effect sealed between aluminium sheet 1 and car body, can play again the effect of damping, reduces car body vibrations and is delivered on aluminium sheet 1.It addition, the cross section of aluminum section frame 2 is U-shape structure, seal washer is fixed on aluminum section frame 2.
In order to obtain higher-quality rolling stock aluminum skirtboard so that rolling stock aluminum skirtboard has higher flatness, the present embodiment rolling stock aluminum skirtboard following processing method of employing:
Step 1, on aluminium sheet 1, it is processed to form vent 11, and on aluminium sheet 1, offers multiple installation through hole 12；Wherein, diameter 0 mm bigger than the diameter of the rivet joint screw 4 ~ 0.1mm of through hole 12 is installed.Concrete, the diameter diameter not less than rivet joint screw 4 of through hole 12 is installed, and it is less to install the size that through hole 12 goes out greatly, may insure that rivet joint screw 4 is in riveting process, the riveting end of rivet joint screw 4 can be good at being embedded in aluminium sheet 1, it is ensured that the bonding strength between rivet joint screw 4 and aluminium sheet 1 is sufficiently large.
Step 2, aluminum section frame 2 is welded on aluminium sheet 1.
Step 3, at the riveting end anti-electric dispergation of uniform application of rivet joint screw 4, rivet joint screw 4 smears the scope thickness not less than aluminium sheet 1 of anti-electric dispergation.Concrete, the thickness of aluminium sheet 1 can use the plate body of 3mm, then the anti-electric dispergation of 3mm altitude range is at least smeared in the riveting end of rivet joint screw 4, anti-electric dispergation can effectively avoid occurring between rivet joint screw 4 and aluminium sheet 1 chemical reaction, rivet joint screw 4 uses rustless steel to make under normal circumstances, kept apart by anti-electric dispergation between rivet joint screw 4 and aluminium sheet 1, it is to avoid aluminium sheet 1 occurs chemical reaction the phenomenon of corrosion occur, it is ensured that remain higher bonding strength between rivet joint screw 4 and aluminium sheet 1.
Step 4, the rivet joint screw 4 smearing anti-electric dispergation is pressed into installation through hole 12 in, pressure at right angle suffered by rivet joint screw 4 is in the range of 28.2KN ~ 29.5KN, the riveting end making rivet joint screw 4 is completely embedded in aluminium sheet 1, the surface of the riveting end of rivet joint screw 4 is with the visible face of aluminium sheet 1 in the same plane, simultaneously so that the angle between rivet joint screw 4 and aluminium sheet 1 is in the range of 90 ° ± 0.5 °.Concrete, rational pressure at right angle is used to be pressed into by rivet joint screw 4 in installation through hole 12, may insure that on the premise of rivet joint screw 4 can be good at being pressed into installation through hole 12, effectively avoid around installation through hole 12, occurring that impression destroys aluminium sheet 1 surface quality because pressure is excessive, it is ensured that aluminium sheet 1 has higher flatness.
Step 5, the rivet joint screw 4 being embedded in aluminium sheet 1 being applied pretightning force, the moment of pretightning force is in the range of 5.1N/m ~ 8N/m.nullConcrete，The effect of rivet joint screw 4 is to be fixedly mounted on aluminium sheet 1 by miscellaneous part，In installation process，Rivet joint screw 4 is by the power by nut，And after rivet joint screw 4 is embedded in aluminium sheet 1，By rivet joint screw 4 is applied suitable pretightning force，So that rivet joint screw 4 is more firmly fixed on aluminium sheet 1，The more important thing is，Rivet joint screw 4 is by after pretension，The surrounding installing through hole 12 can occur a certain amount of deformation accordingly，Aluminium sheet 1 sprayed paint laggard luggage join filter 3 time，On rivet joint screw 4 during clamp nut，Rivet joint screw 4 will stress，And now，Owing to rivet joint screw 4 is by pretension mistake，The surrounding's deformation quantity installing through hole 12 on aluminium sheet 1 is less，To avoid the visible face of aluminium sheet 1 to occur, impression makes the skin of paint on aluminium sheet 1 rupture，Guarantee the surface smoothness of aluminium sheet 1.
Step 6, visible face to aluminium sheet 1 scrape mud and process of spraying paint, to form smooth skin of paint in the visible face of aluminium sheet 1.Concrete, after aluminium sheet 1 sprays paint, the visible face of aluminium sheet 1 just reaches the requirement dispatched from the factory, and its flatness reaches the highest.
On step 7, the rivet joint screw 4 that filter 3 is fastened on around through hole by nut.Concrete, finally filter 3 parts such as grade are installed again on aluminium sheet 1, now, owing to the rivet joint screw 4 on aluminium sheet 1 have passed through the pretension process of step 5, in rotating nut fastener cycle, the visible face of aluminium sheet 1 does not haves obvious impression, it is ensured that the skin of paint on aluminium sheet 1 keeps complete, it is thus achieved that the aluminum skirtboard of high-flatness.
Rolling stock aluminum skirtboard and the processing method thereof that the present invention provides, by offering vent on aluminium sheet and being arranged around rivet joint screw at vent, filter is arranged on aluminium sheet by rivet joint screw, first rivet joint screw is directly riveted on aluminium sheet the deflection that can effectively reduce aluminium sheet, guarantee the requirement to flatness of the aluminum skirtboard, and outside air can enter into the inner side of aluminium sheet by vent and filter, substantially increase the performance of ventilating of aluminum skirtboard, realize on the premise of guaranteeing flat appearance degree, improve performance of ventilating and the air purity of rolling stock aluminum skirtboard.
Last it is noted that above example is only in order to illustrate technical scheme, it is not intended to limit；Although the present invention being described in detail with reference to previous embodiment, it will be understood by those within the art that: the technical scheme described in foregoing embodiments still can be modified by it, or wherein portion of techniques feature is carried out equivalent；And these amendments or replacement, do not make the essence of appropriate technical solution depart from the spirit and scope of various embodiments of the present invention technical scheme.
