Description
Technical field
The invention belongs to process for treating surface, it is related to the turbo blade residual abrasive material cleaning method after abrasive Flow Machining
Improvement.
Background technology
Abrasive Flow Machining technology is a kind of up-to-date machining process, and it is with abrasive medium (one kind mixed with abrasive material
Flowable mixture) under pressure flow through the required surface processing of workpiece, carry out deburring, deburring, angle rounding, to reduce
The percent ripple of surface of the work and roughness, reach precision machined fineness.Abrasive material is mostly aluminium oxide, carborundum, boron carbide
Deng.After the electric machining film cooling holes of aero engine turbine blades surface, for removing internal channel and hole burr, using abrasive Flow
Process technology is processed.Although abrasive Flow Machining technology removes flash removed effect highly significant, because turbo blade is narrow
Internal channel and the less aperture of diameter, easily residual wherein, is cleaned extremely difficult to lead to sticky abrasive material.Current cleaning side
Method is: the turbo blade after abrasive Flow Machining is immersed in 10min～30min in the container fill aero-washing gasoline, afterwards,
Turbo blade is taken out from aero-washing gasoline, room temperature is dried.Because current cleaning method is difficult to clean off in turbo blade
The abrasive material of chamber residual, when proceeding to vacuum brazing operation, leads to turbo blade to be reported because batch corrode in vacuum brazing
Useless, the qualification rate of vacuum brazing is low, and only less than 20%.
Content of the invention
The purpose of the present invention is: proposes the cleaning side that a kind of improved turbo blade after abrasive Flow Machining remains abrasive material
Method, thoroughly to remove the abrasive material of turbo blade inner chamber residual, it is to avoid batch corrode during vacuum brazing operation, improves true
The qualification rate of empty soldering.
The technical scheme is that the turbo blade after abrasive Flow Machining remains the cleaning method of abrasive material, its feature
It is: the step of cleaning is:
1st, oscillation cleaning: turbo blade is neatly laid in the part basket of bar section of stainless steel welding, only spreads one layer of turbine
Blade, part basket is hung on the suspension hook of crane, puts into and fills liquid trichloroethylene solvent, the rinse bath with heater
In it is ensured that trichloroethylene solvent submergence turbo blade；Often standing cleaning 20min～30min is shaken up and down by crane at room temperature
Dynamic part basket 3min～5min, carries out oscillation cleaning, the cycle-index of standing cleaning-oscillation cleaning is 2 times～4 times；
2nd, vapour degreasing: in the Steam area of top part basket being suspended in rinse bath, the basket bottom of part basket is to trichlorine
The distance of ethylene solvent liquid level is 0.5m～1m, starts the heater of rinse bath, the trichloroethylene solvent in rinse bath is added
Heat arrives boiling point, and turbo blade is carried out with trichloroethylene steam oil removing, and the vapour degreasing time is 10min～30min, then uses from the beginning
Water rinses turbo blade 3min～5min；
3rd, high pressure water washing: be 40kg/cm using pressure2Room temperature tap water high pressure water flushing is carried out to turbo blade inner chamber
Wash 3min～5min；
4th, check inner chamber: all visibility regions visually inspect to turbo blade inner chamber using endoscope, if not residual
Stay abrasive material, then cleaning terminates；If still there being residual abrasive material, repeat step 1 to step 4, till not remaining abrasive material.
The invention has the advantage that proposing the cleaning that a kind of improved turbo blade after abrasive Flow Machining remains abrasive material
Method, can thoroughly remove the abrasive material of turbo blade inner chamber residual, it is to avoid batch corrode during vacuum brazing operation, improve
The qualification rate of vacuum brazing.One embodiment of the present of invention, tests prove that, thoroughly removes the mill of turbo blade inner chamber residual
Material, improves the qualification rate of vacuum brazing, and qualification rate is more than 99%.
