Description
Technical field
Patent of the present invention is related to a kind of production technology that is welded of distribution transforming fuel tank especially bellows wall Oiltank structure.
Background technology
Current domestic distribution transforming fuel tank is welded, and production technology is welded using blanking, fuel tank skeleton group, bellows wall group is welded, fuel tank is full
Weldering, fuel tank scarfing cinder polishing, fuel tank suppress the processes such as leak test, fuel tank repair welding, fuel tank acid washing phosphorization, fuel tank leaching priming paint, fuel tank drying.
Above-mentioned process has the following disadvantages：
1st, after bellows wall and skeleton group, full weld there is water inside bellows wall and skeleton lap-joint and bellows wall in acid washing phosphorization
Sour problem of rustiness is deposited, transformer station high-voltage side bus safety is influenceed, influences product quality；
2nd, bellows wall trigonum is larger, needs each trigonum of special messenger's spot welding, organizes postwelding full weld, time-consuming, inconvenience machine
Device people welds and industrial upgrading；
3rd, skeleton and bellows wall group postwelding have 4 cross joints to need full weld, waste wlding and time, inconvenience positioning and mass
Production；
4th, need polishing welding seams, cleaning to splash after the completion of fuel tank full weld, waste time and energy, efficiency is low；
5th, artificial full weld, weldquality are had a great influence by personnel's technical ability, and weldquality is unstable；
6th, in welding process, whole fuel tank need to be repeatedly overturn, is wasted time and energy.
The content of the invention
In view of the above-mentioned problems existing in the prior art, the present invention provides a kind of efficient distribution transforming fuel tank and is welded production technology side
Method, its technical scheme taken are：
The specific process of the technique is as follows：
1）Blanking
With punching (shearing) machine to angle-steel blanking, punching, knock open-minded, with plasma cutting blanking steel plate, bender bending and molding is
The collet of one box-shape；
2）Fuel tank skeleton group is welded
With dedicated set mounted welder welded together along welding fabrication, then with collet, corner support angle steel group on fuel tank skeleton；
3）Fuel tank skeleton full weld
Using mould location and installation on 2 axle positioners, adding two guarantor's welding machine full welds with 6 axle robots, the linkage of 8 axles is welded,
Also can artificial full weld；
4）Fuel tank skeleton ball blast
Shot-blast apparatus has 4 ramming heads to be distributed in shot blast room both sides, and fuel tank skeleton is hung on hanger, hanger upper end installation tooth
Wheel, 1 rev/min of spinning is driven by reducing motor, the another both sides of shot blast room, which set gate, can automatically turn on closing, enter after the completion of ball blast
Air channel siphons away surface dirt；
5）Bellows wall makes
Bellows wall mould bending arc radius≤1mm, bellows wall welding use argon arc welding, increase by a wire vent machine at trigonum
Structure, trigonum make trigonum fill and lead up substantially using the filled method of argon arc welding；
6）Bellows wall acid washing phosphorization
With degreasing, washing, pickling, washing, table tune, phosphatization, passivation, washing, totally 8 processes are handled；
7）Bellows wall full weld after fuel tank and acid washing phosphorization after ball blast
Using mould positioning and clamping bellows wall, on 2 axle positioners, added with 6 axle robots without the two guarantor's welding machines that splash
Full weld, the linkage welding of 8 axles；
8）Fuel tank suppresses leak test
Fuel tank back-off, with automatic hydraulic, mechanism is pressed on valve rubber, and valve rubber middle opening is inwardly inflated, gas ducting
Upper installation pressure gauge, after pressure is suppressed in arrival, fuel tank weld seam spray leakage testing liquid finds leak source；
9）Fuel tank first drying
Using the stainless steel stove of heated by natural gas, hot blast is sent into baking oven with high-temperature blower, baking oven doorway is designed as downwards
45 ° of ramps, prevent hot gas from doorway overflow；
10）Fuel tank plastic-spraying
Using 6 axle robot plastic-sprayings, manually suitably make up a deficiency, molding powder is recycled secondary automatically using whirly or willy-willy
Use；
11）Fuel tank secondary drying
Chain is put using collection and is transferred into drying tunnel, each fuel tank is lined up disengaging drying tunnel, using the stainless steel stove of heated by natural gas, uses
High-temperature blower is sent into hot blast in baking oven, and baking oven doorway is designed as 45 ° of downward ramps, prevents hot gas from being overflowed from doorway.
The present invention changes traditional handicraft by the welding procedure side of overall full weld again after the completion of fuel tank skeleton, the weldering of bellows wall group
Method, by Shot Blasting after fuel tank skeleton group weldering full weld, bellows wall acid washing phosphorization, then skeleton after bellows wall full weld with directly applying
Dress, solve bellows wall and acid washing phosphorization after skeleton group, full weld, skeleton and bellows wall crack and internal water in former technological process
Sour problem of rustiness is deposited, the product quality of distribution transforming transformer can be effectively improved；Ripple bellows wall is by changing mould structure and welding side
Trigonum is obviously reduced in method, goes to zero substantially, and without the direct full weld bellows wall in spot welding trigonum, it is automatic to be easy to implement robot
Welding, industrial upgrading is realized, and weldquality is stable；Weld seam on fuel tank skeleton, direct Shot Blasting of splashing, without manually beating
Mill cleaning is splashed, and is saved manually, is improved efficiency.
Present invention, avoiding the water of skeleton and bellows wall welding after integral in acid washing phosphorization to deposit sour problem of rustiness；Make
Oiltank structure becomes simple, and bellows wall trigonum goes to zero substantially, without a group weldering welding trigonum, direct full weld, is easy to positioning group
Weldering and batch production, are easy to utilize robot welding, realize industrial upgrading.
