Description
Technical field
The invention belongs to aluminum alloy solder technology fields, are related to a kind of big gooseneck container side plate welding procedure.
Background technique
Aluminium alloy density 2.7g/cm3, only the 1/3 of steel, aluminium alloy corrosion resisting property is good, is not required to any safeguard procedures
Long-term to maintain any surface finish, in addition aluminium alloy also has good welding and moulding processing performance.To meet wanting for energy-saving and emission-reduction
Ask, automotive light weight technology has become the common recognition of automobile industry, and largely using aluminium alloy element be automobile lightweight the most
Feasible mode.However, intensity of aluminum alloy is low compared with steel, thus use is somewhat limited.
Semitrailer is a kind of widely used heavy duty transport vehicles, and to meet intensity requirement, semitrailer is adopted more at present
Use steel component；Though all aluminium alloy semitrailer product also appears in the newspapers, in the level for also predominantly staying in tank truck and van,
It can not be extended to framework type container semi-trailer, this is primarily due to the left and right sides when assembling of framework type container semi-trailer vehicle
Side plate leads to assembly difficulty because deformation is larger.
Container side plate is made of upper lower-edge beam and intermediate carriage profile, in original container side plate welding production
In, since the weld seam of side plate is long straight weld and asymmetric weld seam (such as attached drawing 1), the bad control of welding process, post welding distortion is super
Difference, in vehicle assembling later, side plate leads to container side plate assembly difficulty because deformation is larger.And there are larger welding changes
After the container side plate assembly of shape, it is also easy to produce stress concentration, welding bead at the serious influence container side plate docking carriage profile of meeting
Quality.
Since container side plate welding bead is longer, mechanical adjusting can only be available using flame repairing, and flame repairing
Range is larger, very high to operator's requirement, if not controlling the temperature and speed of adjusting, can largely reduce base material machine
Tool performance, and under severe welding condition, operator are easy fatigue, it is difficult to the long period keep welding stability and
Consistency will result in low efficiency, energy consumption height and unstable quality of welding etc., and it is poor to weld rear surface finish.
The welding sequence that initial stage takes is first side plate front and back sides solid point, and then the long weld seam in welding inside, overturning are welded again
Then the long weld seam in outside is broken weld seam on the inside of reverse welding again；Entire welding process overturning number is more, wastes time manpower,
Influence production efficiency.
Summary of the invention
In view of this, the present invention wastes to solve container lateral plate welding method overturning in the prior art often
Time and manpower, the low problem of production efficiency provide a kind of big gooseneck container side plate welding procedure.
In order to achieve the above objectives, the present invention provides a kind of big gooseneck container side plate welding procedure, comprising the following steps:
A, it is integrally organized according to drawing pair, container side plate is placed on tooling platform, it is on the outside of container side plate upward, interior
Side downward, before upper lower-edge beam on the outside of container side plate and the welding of side plate weld seam, long weld seam on the inside of first solid point twice, then solid point
Long weld seam on the outside of twice finally welds two road length weld seams of outside according to welding parameter, and wherein welding current is 120~140A, weldering
Connecing voltage is 19.7~22.0V, and speed of welding 90cm/min, after the completion of weld seam welding, two road length weld seams on the inside of reconditioning make to weld
Road is smooth and uniform；
B, side plate is subjected to reversible deformation after the completion of the side bar welding up and down on the outside of side plate, by cushion block pad in tooling when reversible deformation
Between platform and side plate, so that the arc-shaped shape of side plate, maximum height≤125mm of the side plate apart from tooling platform, then weld side
Weld seam is broken between profile material, carries out the welding of lower section weld seam after upper sections weld seam is cooling when welding etc. again；
C, the lower-edge beam of side plate lower end and lower-edge beam decorative panel are welded, welding current is 120~140A, and weldingvoltage is
19.7~22.0V, postwelding polish weld seam；
D, side plate is become at neck and reinforcer at side plate change neck is fixedly mounted by fastener.
Further, the long weld seam in inside and each solid point length of the long weld seam in outside are between upper lower-edge beam and side plate in step A
40mm, between two solid point weld seams between be divided into 500mm.
Further, the weld seam that is broken between step B latus inframedium profile is 4 sections, and every segment length is 200mm, is broken weld seam weldering
Using the welding sequence of first intermediate and then both sides when connecing.
Further, the height of cushion block is followed successively by 125mm, 85mm and 50mm from centre to both sides in step B, wherein 85mm high
The distance between cushion block be 6000mm, the distance between cushion block of 50mm high is 11000mm.
Further, it is 70~90 that step B, which interrupts welding line number,.
Further, step B is broken gap≤2mm between weld seam and adjacent side plates.
Further, step D side plate becomes the fixed form of reinforcer at neck as riveting, and institute is followed successively by interior hexagonal using fastener
Flat cheese head screw, plain washer and nylon are anti-to send hex nut.
The beneficial effects of the present invention are:
1, big gooseneck container side plate welding procedure disclosed in this invention, guarantees weld seam on the basis of original welding procedure
Welding deformation is substantially reduced under the premise of quality；Prestrain method is used in the welding process, reduces welding deformation amount；Improve weldering
Sequence is connect, left plate is reduced and overturns number, improve production efficiency, yield rate, reduce production cost.
2, big gooseneck container side plate welding procedure disclosed in this invention, it is original to determine welding procedure welding parameter just for electricity
Flow 140-160A, 19.7~22.0V of voltage, speed of welding 75cm/min.Since speed of welding is slower, the heat of generation can not be fast
Speed dissipates, and causes plate-side plate welding deformation larger.Under the premise of meeting weldquality, requiring suitably to mention within the scope of welding current
High bonding power improves speed of welding to 90cm/min, accelerates the dissipation speed of weld seam ambient heat, to reduce welding deformation
Amount, and improve production efficiency.
