Description
Technical field
The present invention relates to the restorative procedures of part injury, and in particular to a kind of reparation of stainless steel material conduit outer damage
Method.
Background technique
Conduit is the necessary component part of aero-engine, is laid in external engine, is that engine work is defeated
Send fuel oil, lubricating oil and air.Outer conduit material uses 1Cr18Ni9Ti, wall thickness 1mm, conduit diameter etc..In engine
Situations such as often will appear bump injury, impression in maintenance or the assembly of conduit, decomposition and use process, scratching.At present for
Bump injury, impression, degree of impairment of the scratch depth less than 0.2mm are repaired essentially by the method repaired is thrown.But for damage
The conduit of depth 0.2mm-0.6mm is scrapped because that can not repair as shown in attached drawing 1,2, influences the repair cost of engine.
Summary of the invention
The present invention provides a kind of restorative procedure of stainless steel material conduit outer damage, solve the serious bump injury of conduit,
Impression, scuffing equivalent damage can not repair problem, reduce the scrappage of conduit, improve conduit life and reliability.
Technical scheme is as follows:
A kind of restorative procedure of stainless steel material conduit outer damage, includes the following steps:
Step 1: the conduit of damage is cleared up；
Step 2: conduit is fixedly installed on platform by two fixators, damage location is polished into depth
0.6mm, 5 × 10mm of area2Uniform shapes, and polish；
Step 3: the same stainless steel solder stack of diameter 1.6mm, length 30mm are welded to damage location；The mistake of repair welding
Toward conduit cavity blowing argon gas in journey；
Step 4: it flushes, and polishes with catheter substrate at polishing built-up welding；
Step 5: fluorescence, logical ball and leak check are carried out to the conduit after repair welding.
The restorative procedure of the stainless steel material conduit outer damage, wherein the fixator includes support, bolt, tune
Whole pad and two arc clips, two supports are fixedly installed on the platform, and two arc clips snap together, institute
It states bolt the both ends of the arc clip are separately mounted on two supports, be equipped between the bolt and the support
The inner surface of adjusting pad, the arc clip posts cushion.
The invention has the benefit that the present invention is repaired to the serious conduit of damage, method is simple, is easy behaviour
Make.The scrappage of conduit is reduced simultaneously, saves production cost.
Detailed description of the invention
Fig. 1 is that conduit clip card hurts outside drawing；
Fig. 2 is that conduit scratches outside drawing；
Fig. 3 is repair welding conduit working state schematic representation；
Fig. 4 is fixer structure figure.
Specific embodiment
A kind of restorative procedure of stainless steel material conduit outer damage, includes the following steps:
Step 1: checking catheter injury position, determines damage tolerance 0.4mm, (deep beyond the standard for allowing throwing to repair
Spend 0.2mm)；The conduit for damaging 0.4mm is cleaned up with clean gasoline, and is dried up with dry compressed air；Magnifying glass
It checks cleaning rear tube, determines the depth and area at catheter injury position；
Step 2: it as shown in Figure 3,4, in order to control conduit 1 in repair process because of Light deformation caused by repair welding, will affect
The conduit 1 of damage is fixedly installed in platform 4 with two fixators toward the concentricity problem assembled on engine by further conduit
On；The fixator includes support 6, bolt 7, adjusting pad 8 and two arc clips 5, and two supports 6 are fixedly installed in institute
It states on platform 4, two arc clips 5 snap together, and the both ends of the arc clip 5 are separately mounted to two by the bolt 7
On a support 6, adjusting pad 8 is equipped between the bolt 7 and the support 6, the inner surface of the arc clip 5 posts soft
Pad 9；The conduit 1 is placed between two arc clips 5, and wherein damage location 2 is located in two fixators towards surface
Between position, the L value between two fixators is adjusted to 10mm~15mm, 7 screw-down torque 10N.m of bolt；Conduit 1 will be damaged simultaneously
One end connect with the connector of argon bottle 3；With sander by the damage location 2 of conduit 1 be polished into depth 0.6mm, area 5 ×
10mm2Shape, then damage location 2 is polished with fine sandpaper, until there is metallic luster；
Step 3: choosing solder 1Cr18Ni9Ti or 0Cr18Ni9 identical with conduit material, and the specification of welding wire is fixed are as follows:
Diameter 1.6mm, length 30mm, welding current 45A, welding gun 12L/min, with manual argon arc welding, from damage location center, clockwise
It is a-circle-by-a-circle that solder stack is welded to around catheter injury position at 1-2mm, and the solder of built-up welding is made to be higher than catheter substrate surface
0.5mm；Toward conduit cavity blowing argon gas during manual repair welding, Argon speed is 6L/min, prevents conduit by burn-through；
Step 4: 30 minutes after repair welding, matrix position is exceeded to reparation along conduit diameter periphery with electronic grinding apparatus
Solder is polished, and flushes solder with catheter substrate, then at the built-up welding with fine sand paper polishing repair welding；
Step 5: removing the conduit after repairing, and carries out fluorescence, logical ball and leak check.
Claims (2)
