Description
Technical field
The present invention relates to a kind of small oil tank of transformer hanging axis welding method of welding deformation, belongs to welding equipment technology neck
Domain.
Background technology
Oil tank of transformer hanging axis is load-bearing force part to be used in transformer lifting, transportational process.Regular alternating current transformation
Device product hanging axis is complex by backing plate, the reinforcement composition such as iron, thick cyclinder, structure.At present, such a structure hanging axis is welded to oil
After case tank wall, due to welding heat concentrate, cause herein tank wall welding deformation it is larger, and due to hanging axis rigidity it is stronger, shaping is stranded
Difficulty, so as to be impacted to oil tank of transformer internal diameter size and tank wall flatness, and then influences the electric property of transformer.
The content of the invention
The object of the present invention is to provide a kind of small oil tank of transformer hanging axis welding method of welding deformation, by varying hanging axis
The welding sequencing of each parts, reduces heat and internal stress after welding, improves product quality, solves background technology and deposits
The above problem.
The technical scheme is that：
A kind of small oil tank of transformer hanging axis welding method of welding deformation, step are as follows：
1. spot welding integral plate is adjacent at the position back side that transformer box wall needs to weld hanging axis, in transformer box wall and overall steel
Backing plate is equipped between plate；
2. welding two blocks of steel plates in cross arrangement in thick cyclinder or round steel, hanging axis is formed；
3. position is equipped with the rectangular slab of circular open centered on fixed plate, the diameter of circular open be greater than or equal to thick cyclinder or
The outside diameter of round steel, the bottom of hanging axis at fixed plate circular open with welding, and postwelding polishes, the bottom of hanging axis and the bottom of fixed plate
In same level, fixed plate and hanging axis are integrally welded；
4. the weld seam between integrally welded fixed plate and hanging axis and transformer box wall is welded；It is in cross that four, which are strengthened iron,
The surrounding of hanging axis is evenly arranged in, the bottom of four reinforcement iron is vertically welded in fixed plate and transformer box wall, then by four
A side for strengthening iron is welded with hanging axis, that is, completes operation.
The thickness of the integral plate is not less than 25mm, and the thickness of backing plate is 4~6mm, the length and width of integral plate
It is all higher than hanging axis and strengthens the length and width of iron.
Lower face at the fixed plate circular open is equipped with bevel, and bevel size is 10*45 °.
The iron bottom inside of strengthening is equipped with the gap to match with fixed plate.
The backing plate can be welded on transformer box wall and become one structure, and can also separate knot with transformer box wall
Structure.
The thickness of the fixed plate is 1mm.
The positive effect of the present invention：By being modified to the welding sequence of each parts of oil tank of transformer hanging axis, increase
The sealing run of fixed plate and thick cyclinder, eliminates the weld seam of thick cyclinder and tank wall, reduces the internal stress after welding,
The requirement of fuel tank internal diameter size and tank wall flatness is met, ensure that product quality.

Embodiment
The present invention is described further with reference to the accompanying drawings and examples：
A kind of small oil tank of transformer hanging axis welding method of welding deformation, step are as follows：
1. spot welding integral plate 5 is adjacent at the position back side that transformer box wall 7 needs to weld hanging axis, in transformer box wall 7 and whole
Backing plate 6 is equipped between body steel plate 5, makes certain anti-deformation；
2. two blocks of steel plates 4 in cross arrangement of welding in thick cyclinder or round steel 1, form hanging axis, cross steel plate increase is hung
The stress intensity of axis；
3. position is equipped with the rectangular slab of circular open centered on fixed plate 2, the diameter of circular open is greater than or equal to thick cyclinder
Or the outside diameter of round steel 1, the bottom of hanging axis at 2 circular open of fixed plate with welding（The 10*45 ° of welding of inner side bevel）, postwelding mill
Flat, in same level, fixed plate 2 and hanging axis are integrally welded for the bottom of hanging axis and the bottom of fixed plate；
4. the weld seam between integrally welded fixed plate 2 and hanging axis and transformer box wall 7 is welded；It is in ten that four, which are strengthened iron 4,
Font is evenly arranged in the surrounding of hanging axis, and the bottom of four reinforcement iron 4 is vertically welded in fixed plate 2 and transformer box wall 7,
The side of four reinforcement iron 4 is welded with hanging axis again, that is, completes operation（Strengthen iron finally to weld with hanging axis weld seam, to discharge it
Welding stress when its position is welded, Reducing distortion, prevention weld seam postwelding crackle）.
