Abstract
The invention discloses a deformation repair method for sealing sheets and adjusting sheets of K24 cast alloy material. The method is characterized in that a stable heat treatment method is adopted for repairing deformation; the method comprises the following stable heat treatment process flow: heating to the temperature of 1,160+/-10 DEG C, keeping for 2 to 4 hours, and cooling to the temperature of 750 DEG C in a furnace; and the stable heat treatment is carried out in an argon environment. The deformation repair method for the sealing sheets and the adjusting sheets of K24 cast alloy material is determined through a large quantity of technical researches and tests; through field experiments, the deformation of parts can be reduced by more than 70 percent (the sealing sheets and the adjusting sheets with the deformation of 6 to 10.5 millimeters can be repaired to be within 3 millimeters); and various technical indexes of the repaired parts meet the requirements, and the repaired parts have important application value. The method creatively realizes normalized repair of deformation of the sealing sheets and the adjusting sheets of the K24 cast alloy material, and has high economic value.
Description
Technical field
The present invention relates to technical field of metal material heat treatment, specifically provide a kind of K24 cast alloy materials diaphragm seal and adjustment sheet deformation repair method.
Background technology
Aero-engine closing in spout adopt in large quantities K24 cast alloy materials manufacture diaphragm seal and adjustment sheet, K24 cast alloy materials has high temperature resistant, corrosion resistance, more this material is applied to receive and expands nozzle position, these position parts bear the effect of high temperature and tension at work, cause diaphragm seal and adjustment sheet distortion, diaphragm seal after distortion and adjustment sheet engine in operational state and cruising condition time, receive and expand spout clamping stagnation, engine speed can not be promoted or decline, Engine Control System even can be caused disorderly, to such an extent as to bring grade accident.
K24 cast alloy materials diaphragm seal and adjustment sheet deformation repair method.
Summary of the invention
The object of this invention is to provide the excellent K24 cast alloy materials diaphragm seal of a kind of technique effect and adjustment sheet deformation repair method.
The invention provides a kind of K24 cast alloy materials diaphragm seal and adjustment sheet deformation repair method, it is characterized in that: adopt steady heat processing method reparation distortion; Concrete steady heat treatment process code is as follows: be warmed up to 1160 ± 10 DEG C, keeps 2-4 hour, is cooled to 750 DEG C in stove; Require to carry out steady heat process under ar gas environment.
The specific requirement of described K24 cast alloy materials diaphragm seal and adjustment sheet deformation repair method is as follows successively: use gasoline to rinse part, then dry; Afterwards part is fixed on fixture (according to concrete diaphragm seal different with the structure of adjustment sheet and select corresponding fixture); Again the fixture installing part is lain in a horizontal plane in pot arch; Connect argon gas air feed and exhaust hose, argon gas blows 15-20 minute; Steady heat process is carried out according to stablizing heat treated concrete regulatory requirements; Cooling; Clamper for disassembling; Check flatness, if defective, then carry out 1-2 steady heat processing procedure.
Operated according to following requirement before described K24 cast alloy materials diaphragm seal and adjustment sheet Deformation Repair: flatness inspection; Also flatness inspection is carried out after the repair; Thereafter carry out fluoroscopy again, and carry out riveted joint assembling, then submit inspection to;
The specific requirement of described flatness inspection is: visual examination also measures diaphragm seal and adjustment sheet base plate soffit plane degree with dial gauge on verifying bench, requires that the workpiece deformation amount after repairing is within 3mm.
Visual examination with the general dial framework of band dial gauge (the range suggestion can surveying deflection at least should be 10mm) and base plate " A " the soffit plane degree of measuring tool conjunction measuring diaphragm seal and adjustment sheet on verifying bench.The present embodiment is after carrying out the reparation operations such as steady heat process for " A " bottom surface workpiece of deflection between 6 ~ 10.5mm, residue angularity can be below 3mm.If " A " soffit plane degree is greater than 10.5mm before repairing, then usually require directly to change diaphragm seal or adjustment sheet.
The present invention is tested by a large amount of researches of technique, determine K24 cast alloy materials diaphragm seal, adjustment sheet deformation repair method, part deformation amount can be reduced more than 70% (within the diaphragm seal of distortion 6-10.5mm and adjustment sheet can being repaired 3mm) through field experiment, parts all technical after reparation meets the requirements, and has important using value.
Index: the diaphragm seal of K24 cast alloy materials and adjustment sheet can reach engine instructions for use after repairing.
The present invention creatively achieves standardization and repairs the diaphragm seal of K24 cast alloy materials and the distortion of adjustment sheet, and it has great economic worth.
