Specific embodiment
It should be noted that in the absence of conflict, the features in the embodiments and the embodiments of the present application can phase
Mutually combination.The present invention will be described in detail below with reference to the accompanying drawings and embodiments.
Fig. 1-Fig. 3 is shown according to some embodiments of the present invention.
As shown in Figure 1, a kind of bus body side wall skin structure, including side wall frame and side wall skin, the side wall
Skeleton is by 8 welding fabrication of upper beam 7, lower beam 6 and several diagonal braces, wherein upper beam 7, the laterally setting, and phase of lower beam 6
Mutually parallel, diagonal brace 8 is obliquely installed, and is connected between lower beam 6 and upper beam 7, wherein if upper beam 7, lower beam 6 and
The lateral surface of dry diagonal brace 8 is coplanar, provides a smooth benchmark for the welding of subsequent side wall skin, in addition, lower beam 6 is rectangle
Pipe, upper beam 7 are shape tube, and the section of shape tube is step-like in single layer, the step with a thickness of 10mm.
Specifically, side wall skin includes: the upper seam allowance of covering main body 5,5 one end of covering main body for connecting with upper beam 7
1,5 other end of covering main body is used for the lower seam allowance 2 connecting with lower beam 6, wherein sets between the upper seam allowance 1 and covering main body 5
It is equipped with arc flanging 3, right angle flange 4,3 part-structure of arc flanging and upper cross are equipped between the lower seam allowance 2 and covering main body 5
The arc-shaped edges of beam 7 match, and make the lateral surface of upper beam 7 and covering main body 5 retains certain gap, lower seam allowance 2 under
Crossbeam 6 is fixedly connected, due to the presence of right angle flange 4, so that the lateral surface of lower beam 6 and covering main body 5 keep certain interval.
Wherein, the flanging depth of right angle flange 4 is 10mm, and the flanging depth of arc flanging 3 is 20mm, due to upper beam 7
Step with a 10mm thickness, so that 5 place plane of covering main body and upper beam 7, lower beam 6, there is 10mm between diagonal brace 8
Thick fault-tolerant gap.
Wherein, in body side wall stressed-skin construction, due to using the side wall skin with folded edges, so that side wall frame
There is certain thickness fault-tolerant gap between covering main body 5, it is possible to prevente effectively from because side wall frame out-of-flatness and welding are made
At splashing, deformation cause skin-surface out-of-flatness.
Due to there is gap between side wall skin and side wall frame, in order to make side wall skin not generate shaking, glued on diagonal brace 8
Post several swellable tapes different in size, wherein swellable tape generates expansion after vehicle frame electrophoresis, and after swellable tape expansion
Thickness just fill the gap between diagonal brace and covering main body 5 so that entire side wall skin will not generate drum after being installed
The case where packet or shaking, outer surface has very high flatness, is able to satisfy the needs of client.
The present invention provides a kind of skin technologies of bus body side wall skin structure, as shown in figure 3, including following step
It is rapid:
S1, it plate will be placed in double roller rolling die used in production side wall skin, rolling die is by plate both ends roller
Folded edges are pressed into, the side wall skin with right angle flange 4 and arc flanging 3 is formed；Wherein, at the upper seam allowance 1 of side wall skin
For arc flanging 3, folded depth 20 is right angle flange 4, folded depth 10mm at lower seam allowance 2.
S2, lower beam, upper beam, diagonal brace are welded as a whole, and keep the lateral surface of lower beam, upper beam, diagonal brace coplanar
Or it is approximate coplanar, side wall frame structure is constituted, several swellable tapes 9 different in size are then pasted on oblique lateral wall,
Barrier paper is torn off after 9 firm pasting of swellable tape；Wherein, swellable tape selects packing material LY-32 damping expansion adhesive tape, expansion
Adhesive tape with a thickness of 8mm.
S3, it will be welded on side wall frame by the side wall skin of flanging processing, wherein by the upper seam allowance 1 of side wall skin
Weld together with the step surface of upper beam 7, the lower seam allowance 2 of covering and the lateral surface of lower beam 6 is welded together, and use hand
Swellable tape 9 between covering main body 5 and diagonal brace 8 is compacted, meets side wall skin and is come into full contact with swellable tape, cover side wall
Skin claps the requirement having no abnormal sound without recess, shaking, hand.
S4, the body side wall stressed-skin construction for being welded with covering is put into electrophoresis in electrophoresis tank, after electrophoresis, expansion glue
Start to expand on 9 thickness direction of band, and support swelling side wall skin, side wall skin is made not generate the feelings of bulge or shaking
Condition, outer surface have very high flatness.
The foregoing is only a preferred embodiment of the present invention, is not intended to restrict the invention, for the skill of this field
For art personnel, the invention may be variously modified and varied.All within the spirits and principles of the present invention, made any to repair
Change, equivalent replacement, improvement etc., should all be included in the protection scope of the present invention.
