Abstract
The invention discloses a splicing process for the aluminum outer skin of a military shelter. The process comprises the steps of assembling sizing of a skeleton, cleaning before welding, butting positioning, drilling of rivet holes, riveting, detection of planeness, welding of the outer skin, rivet welding, weld grinding and the like. According to the splicing process, a weld crosswise and sequence welding mode is adopted, so that outer skin straight plates can be continuously and seamlessly spliced, the smoothness and strength of a spliced weld can be ensured, and the condition of deformation and cracking is avoided; the outer skin straight plates are riveted through rivets, so that the connection stability of the outer skin straight plates relative to the skeleton can be effectively improved, the waterproof sealing performance of a shelter body of the shelter can be effectively improved, and a paint coating at a seam can be completely prevented from being detached; in addition, the rivets are fastened on the outer skin straight plates and the skeleton by virtue of a three-section welding process, so that the rivets can be effectively prevented from being loosened or separated.
Description
Technical field
The present invention relates to aluminium sheet splicing process technical field is and in particular to a kind of splicing work of Military Shelter aluminum exterior skin
Skill.
Background technology
In automobile industry, compartment outer wall generally requires the eyelid covering covering layer of metal material, especially Military Shelter cabin
Body, needs to cover one layer of aluminum eyelid covering in nacelle outer wall, because aluminum eyelid covering is straight panel structure, so exist a large amount of in splicing
Straight panel and straight panel splicing.The feature of such part is: splicing plate all belongs to big plate, and piece is longer, and outer illiteracy is thin compared with wall, has
Higher hardness and intensity requirement.
Prior art is generally divided into three kinds for the splicing of Military Shelter nacelle eyelid covering, and the first is butt welding, two pieces
Eyelid covering straight panel is docked in the same plane, and using butt welding, splicing welding joint width is generally 0-0.7 times of skin thickness；This
Planting butt welding needs, using Special Automatic welding equipment and welding tooling, the Technology and welding equipment of welding to be required relatively
Height, process equipment cost is high.Second is the docking of cushioning plate, and two pieces of eyelid covering straight panels are docked in same plane, then in splicing weldering
The backing plate of the lower one piece of same thickness of cushioning of seam, two pieces of eyelid coverings form bridging arrangement with backing plate, using spot-welding technology by two pieces of eyelid coverings
Welding；This overlap joint welding procedure is relatively low to welding equipment and welding tooling requirement, but the addition of backing plate but increases entirety
Quality, increased the quantity of solder joint, and welding deformation amount is wayward.The third is overlap joint after die mould, by the weldering of one piece of exterior skin
Edge fit stamps out a step, and the height of step is equal to skin thickness, is welded two pieces of eyelid coverings using spot-welding technology；This die mould
, due to there being the height stile of punching press step, in pinpoint welding procedure, non-deformability is strong for the structure overlapping afterwards, but with second cushioning plate
Docking is similar, equally increased skin thickness and weight.
Obviously, existing splicing cannot realize the seamless spliced of big board-type eyelid covering, especially when eyelid covering is for aluminum,
Have that hardness is low, yielding problem, the splicing that conventional splicing process cannot meet aluminum eyelid covering requires, lead to strong after splicing
Spend low, yielding cracking, cause that nacelle waterproof effect is poor, surface painting layer easily comes off and the defect such as loosing of rivet.
Content of the invention
The present invention is intended to provide a kind of splicing process of Military Shelter aluminum exterior skin, to solve existing eyelid covering splicing process
Existing low intensity, yielding cracking, nacelle waterproof effect is poor, surface painting layer easily comes off and loosing of rivet etc. is asked
Topic.
The present invention is achieved by following technical solution:
A kind of splicing process of Military Shelter aluminum exterior skin, this technique comprises the following steps:
(1) Skeleton assembly school shape: the Skeleton assembly needing the shelter covering exterior skin is put in place, adjustment frame position, chi
Very little and shape；
(2) preweld cleaning: with cleanout fluid cleaning skeleton surface, exterior skin straight panel, remove chalk dust removing and greasy dirt；
(3) butt junction location: two pieces are needed the exterior skin straight panel spliced each other to draw close and is placed on skeleton it is ensured that two pieces outer
The wide weld seam of 3mm is reserved between eyelid covering straight panel；
(4) bore rivet hole: the rivet hole of some array arrangements is uniformly got out on exterior skin straight panel and skeleton；
(5) rivet: insert rivets into rivet in the hole, complete the riveting between exterior skin straight panel and skeleton, after the completion of riveting,
Rivet sinks to exterior skin straight panel 0.8-1.0mm；
(6) detect flatness: after detection riveting, the surface planarity of exterior skin straight panel is it is desirable to flatness≤4mm/m2；
(7) exterior skin welding: intersect spot welding exterior skin straight panel successively to both sides in the middle of weld seam；
(8) rivet welding: the rivet after the completion of riveting is passed through spot-welded in exterior skin straight panel, rivet weld seam is riveting
Clearance space between nail end and exterior skin straight panel；
(9) weld grinding: after the completion of welding, polishing welding seams and rivet weld seam successively.
In described step (2), the cleaning of exterior skin straight panel is included with acetone, gasoline wipes weld seam and buffing machine cleaning table
Surface oxidation film.
Described step (7) is divided into following steps:
(7.1) weld seam is divided into some segmentations, each segmentation is divided into solder joint a and solder joint b；
(7.2) to the solder joint a in each segmentation of both sides successively cross weld in the middle part of weld seam；
(7.3) after all solder joint a cooling, then to the solder joint in each segmentation of both sides successively cross weld in the middle of weld seam
b.
Described step (8) is divided into following steps:
(8.1) the up and down two row rivets adjacent with weld seam are segmentation welding clockwise, and rivet weld seam is divided into clockwise
Three segmentations weld successively；
(8.2) remaining rivet is symmetrical expression on the basis of weld seam and divides three sections of welding.
It is 100mm with the spacing between two neighboring rivet in a line rivet.
Spacing between the two row rivets up and down adjacent with weld seam is 25mm.
The length of described solder joint a and solder joint b is 50mm.
The invention has the beneficial effects as follows:
Compared with prior art, the splicing process of the Military Shelter aluminum exterior skin that the present invention provides, using weld seam segmentation
Cross weld, be capable of continuous, seamlessly joined between exterior skin straight panel it is ensured that spliced splicing welding joint smooth
Property and intensity, are not in the situation of strain cracking；And exterior skin straight panel entire body adopts rivet, can effectively improve outer illiteracy
Skin straight panel, for the stable connection of skeleton, can effectively improve the sealing performance of square-cabin body, prevents seam crossing paint
Coating shedding；Additionally, rivet is fastened in exterior skin straight panel and skeleton also by three-sectional welding technique, can effectively prevent rivet
Loosen or come off.
