Description
Technical field
The invention belongs to the corollary equipment technical field that generates electricity, in particular it relates to which a kind of 600MW outlet boxes take block to going out collimation method
Blue dimensional control methods and outlet box.
Background technology
As unit demand quantitative change of the in the market to 600MW capacity is big, how with foreign same type product competition market
Share etc. be all at present we need in face of the problem of, as the outlet box of one of its important auxiliary equipment, production capacity and quality carry
Rise and just seem particularly critical.Outlet box is the conventional welding of one kind that Stator Coil outlet terminal is led to outside support
Structure, mainly by case, there is flange and manhole flange etc. and form, traditional outlet box gusset is more and small, thin, locational space compared with
It is more, it is inconvenient for operation.Internal structure external structure is optimized using new outlet box, one of pith as outlet box goes out
Collimation method is blue and its takes block, causes rigid body to shift because of vibrations during long-term use, easily cracked, in order to reduce this part
Accident rate, it is necessary to strictly be controlled outlet flanges and its installation dimension for taking block.
The content of the invention
Goal of the invention：For overcome the deficiencies in the prior art, it is an object of the invention to provide a kind of 600MW outlet boxes to take block
To outlet flanges dimensional control methods and outlet box, by reducing spillage of material, optimize Product Process route, design and using special
The measurement frock of industry, purchase special implement control each key position size of product, the step of simplifying production and examine, lifting has
The means such as man-hour ratio are imitated, effectively control the cost of production.
Technical scheme：The invention provides a kind of 600MW outlet boxes to take block to outlet flanges dimensional control methods, including such as
Lower step：
1）The comprehensive laser levelers of line 3D of feux rouges 12 verify to the positioning reference plane of outlet capsule；
2）End socket and case carry out erection welding first；
3）Outlet flanges are assembled with case, and special outlet flanges frock and infrared laser ranging are used in assembling process
Instrument is accurately positioned to the installation site of outlet flanges；
4）Outlet flanges are welded with case, increase Anti-deformation tooling before welding；
5）Take block to be welded with outlet flanges, block assembly tooling is taken to taking block progress erection welding with special；
6）Underframe and two laminates carry out erection welding；
7）Two laminates and case carry out assemble welding；
8）Two laminates and end socket carry out assemble welding；
9）Manhole flange and case carry out assemble welding；
10）Water-output flange, manhole flange and hanger carry out packing and matched somebody with somebody.
Using this dimensional control methods, there are the welding deformation amount of flange and outlet flanges to the size taken at block in control,
Ensure that following process has enough allowance, the welding deformation amount of control outlet flanges can be controlled, it is strict during multi-pass welding
The interlayer temperature of welding bead is controlled, control is finally reached and takes block to the purpose of outlet flanges size.
Further, above-mentioned 600MW outlet boxes take block to outlet flanges dimensional control methods, and the outlet flanges are with taking
Within the mm of deviations from planarity 1 of block.Surface Machining is occurred without during this planarity requirements following process not go out or process not
Uniform situation.
Further, above-mentioned 600MW outlet boxes take block to outlet flanges dimensional control methods, and the outlet flanges are to taking
Within the tolerance+3mm of block.Surface Machining, which is occurred without, during this tolerance guarantee following process does not go out or process inequality
Even situation.
Further, above-mentioned 600MW outlet boxes take block to outlet flanges dimensional control methods, described to take block and go out collimation method
Orchid is heat-treated before being welded.Using heat treatment, the welding deformation amount of outlet flanges and case is eliminated, reduces and takes packaged match somebody with somebody
During caused accumulated error.
Further, above-mentioned 600MW outlet boxes take block to outlet flanges dimensional control methods, the outlet box each several part
The temperature control of preheating is at 150~200 DEG C before welding.Outlet box welding before by preheating temperature be arranged on 150~200 DEG C it
Between, bonding wire energy can be controlled, coordinates rational ultralow hydrogen type welding material, more preferably welding head quality can be obtained.
Further, above-mentioned 600MW outlet boxes take block to outlet flanges dimensional control methods, the outlet flanges and cover
Within the mm of side perpendicularity 1.5 of shell.Ensure the perpendicularity of outlet flanges, increase error when needing to take block welding after avoiding.
Further, above-mentioned 600MW outlet boxes take block to outlet flanges dimensional control methods, using more during the welding
Layer multi-pass welding technique.Weld metal quality can be improved using multi-layer multi-pass welding, rear layer weld seam has heat treatment to front layer
Effect, improves secondary structure.
Further, above-mentioned 600MW outlet boxes take block to the outlet box of outlet flanges dimensional control methods, including envelope
Head, outlet flanges, block, hanger, case, manhole flange, underframe, two laminates and water-output flange are taken, two laminate is located at underframe
On, for the case on two laminates, the case both ends are provided with end socket, and the case is provided with outlet flanges, hanger, enters hole
Flange and water-output flange, the block of taking is on outlet flanges.This outlet box structure is reasonable, can play the work of wire harness separated time
With two laminates of setting ensure that overall structure consolidates and is also devised with the convenient hanger lifted by crane.
Further, above-mentioned 600MW outlet boxes take block to the outlet box of outlet flanges dimensional control methods, the outlet
The outlet flanges of box are provided with bellows-sheathed.Outlet flanges be wire harness at outlet box extraction, set bellows-sheathed can prevent line
Beam can play effect attractive in appearance simultaneously with the friction of line outlet position.
Above-mentioned technical proposal can be seen that the present invention and have the advantages that：600MW outlet boxes of the present invention are taken
Block is rational in infrastructure to outlet flanges dimensional control methods and outlet box, by the comprehensive laser levelers of line 3D of feux rouges 12 to going out
The positioning reference plane of line box assembling is verified, the reasonable arrangement assemble sequence in technical papers, and preferential assembling is also easy to produce size
The outlet flanges of deviation, the installation site in assembling process using special frock and Infrared LASER Ranger to outlet flanges
It is accurately positioned, reduces caused accumulated error in assembling process to the full extent, increase Anti-deformation tooling before welding,
The interlayer temperature of welding bead is strictly controlled during multi-pass welding, increases corresponding heat treatment deformation frock in heat treatment, finally with special
Erection welding is carried out to taking block with assembly tooling, control is finally reached and takes block to the purpose of outlet flanges size.
