Description
Technical field
The utility model is related to tooling and fixture technical field, and tooling is smeared more particularly to a kind of labyrinth piece soldering flux.
Background technology
Labyrinth piece is used for a kind of multilevel decompression structure.Each fluid path has a series of elbow, can limit across
The fluid-pressure drop of valve.Labyrinth piece is welded one by one, so that it may to form the more corner different flows of a multichannel
Labyrinth block, can effectively prevent and wash away, and effectively reduce noise.It is just needed every to make labyrinth piece can make up labyrinth block
Soldering is squeezed to weld on being smeared above the piece of piece labyrinth.Using the advanced configuration of more corner multichannels, operational safety uses
The advantages that long lifespan, High Pressure Difference operating mode, become coal chemical industry, power station industry important equipment.Coal chemical industry, power station special high-pressure difference limen
Medium is High Pressure Difference, high-temperature medium, not only has powerful erosion, the components such as spool and valve seat to valve to the runner of valve body
Sealing surface erosion and abrasion bigger, exit velocity is limited by using the labyrinth block of the more corners of multichannel, erosion can be eliminated
Destruction to trim and valve body.
Generally trowel coating is directly applied with brush in the prior art or directly scratched with scraper plate, due to brush or scraper plate dynamics
Control that the bad welding flux layer that can cause labyrinth piece surface is in uneven thickness, and labyrinth piece is in brazing process if meeting in uneven thickness
There is problems with：
The first, the block of labyrinth after welding in uneven thickness occurs integral inclined.
The second, in uneven thickness to occur thick local solder outflow in the welding process, it is inadequate that solder flux occurs in thin place,
It welds shaky.
The place of solder flux thickness, which may flow out, in third, welding process blocks labyrinth piece corner runner.
Utility model content
Technical problem to be solved in the utility model is：In order to overcome in the prior art flux covering it is non-uniform not
Foot, the utility model provide a kind of labyrinth piece soldering flux smearing tooling.
The utility model solves its technical problem technical solution to be taken：A kind of labyrinth piece soldering flux painting dauber
The end face of dress, including tooling matrix, scraper plate and mandril, the tooling matrix is equipped with bracket groove identical with workpiece shapes, institute
It states mandril and is at least three, and be circumferentially distributed in the bottom of bracket groove, the mandril is through tooling matrix and along tooling matrix
The height of axis direction is adjustable, and when applying trowel coating, workpiece is placed in bracket groove, and workpiece and tooling matrix clearance fit, described to scrape
Plate is for smearing solder flux, and the mandril out of bracket groove for jacking up workpiece.
Further, in order to ensure the uniformity of coating, the depth of the bracket groove is equal to the sum of workpiece and coating layer thickness.Cause
This can directly apply trowel coating, and can ensure the equal of coating layer thickness as long as workpiece is put into bracket groove without any adjustment
Even property and one straightforward.
Further, the mandril includes sequentially connected head and shaft, and the head bottom is plane, and the shaft is remote
One end from head is plane, and the tooling matrix of the middle trench bottom is equipped with the through-hole coordinated with the shaft, and the bar
Body and the tooling matrix clearance fit, preferred gap are 0.5mm~1.0mm.
Further, in order to improve the efficiency of smearing, the width of the scraper plate is more than the width of bracket groove.The width of scraper plate is more than
The width of bracket groove, that is, more than the width of workpiece, thus circumferentially disposably can all smear entire width direction
Upper coating does not have to repetitious blade coating, improves efficiency.
Preferably, the mandril is three, is uniformly distributed circumferentially.Three circumferentially distributed mandrils can either ensure to push up
When going out workpiece, workpiece surface stress equalization is not easy to block, and can guarantee using minimum mandril, reduces cost and the top of tooling
Go out alignment difficulty when operating, in addition, reducing the contact area of mandril and workpiece surface, reduces and damage is generated to workpiece surface
Risk.
Operation principle：
It smears in coating procedure, first according to the thin and thick of workpiece and the thickness of coating can be needed to determine the bracket groove of tooling
Working depth, then put the workpiece in the corresponding bracket groove of tooling, trowel coating then is applied with scraper plate, the width of scraper plate is wide more than workpiece
Degree makes scraper plate equilibrium be placed in tooling both sides, and after coating is smeared, workpiece is ejected with mandril.It is strictly controlled using the depth of slot
The thickness of coating, is placed in tooling both sides using scraper plate and ensure that the thickness of coating is uniform.Between workpiece, mandril and tooling matrix
For a certain amount of clearance fit, ensure easily to take out workpiece.Uniform in labyrinth on piece smearing solder flux using the utility model, solder flux is thick
Degree is guaranteed, and improves welding performance in the welding process.
The utility model has the beneficial effects that：A kind of labyrinth piece soldering flux provided by the utility model smears tooling, not only
With simple and practical, and the advantages of coating uniform, compared to directly applying trowel coating with brush before or directly scratched with scraper plate,
It is significantly improved on thickness, in uniformity and in speed.
