Air cylinder of body of repair air cylinder covers flaw a few kinds of commonly used methods

The mild steel of 5 ～ 3mm board cut fill board, fill board than crackle all round big 20 ～ 30mm; ④ edge fills board all round bore, pitch is L5 ～ 20mm, bore diameter 3 ～ 5mm; ⑤ will fill board enclothe go up in crackle, make its and gas cylinder body or joint of air cylinder lid close together, subsequently in order to fill board enraging the bore on cylinder body or air cylinder lid for example, and tap; ⑥ uses bolt fill board fixed, filling board build with air cylinder body or air cylinder between, can fill up an asbestine mat, or oil of the red lead on the besmear on the face is stuck in two. 2, the law that cut silk into parts this kind of method is commonly used at repair only flaw. Its method is: ① uses φ the two end of crackle get the broach preexistence of 3 ～ 5mm to stop crack aperture 1 with 2, next 2 ～ 4mm gets every other an eyelet 3, 4; ② is getting the tap in good eyelet; ③ comes back red copper marvellous bolt Kong Zhong, the length that comes back and ply of air cylinder wall are identical, cut off red copper club next, its section tower above enrages cylinder body 2mm; ④ uses same method, of the bore in pressing a plan get orderly early or late a series of eyelet, tap comes back red copper marvellous bolt. Chain of a bolt is formed on whole break; ⑤ strikes the put apart part of bolt of riveting red copper gently with small hand hammer, make its riveting smooth and bite each other close; ⑥ is in with crackle of hydraulic law examination finally slack. If have slight and slack. Can continue to use the red copper bolt of leak of ooze of hand hammer light riveting. 3, electric welding law is in with the broach of φ 4mm first two end get crackle stop crack aperture, at the same time edge crackle " V " form groove chamfer, groovy deepness with exceeding airframe wall thick 2 ／ 3 advisable. The metallic welding rod of the 4mm that use φ (need to use sound technology) or fill with solder of cast-iron welding rod below the circumstance that heating. To prevent electric welding place solder hind produces internal stress or warp, every solder should one paragraph from solder with little weight beat gently among two side direction, when taking the advantage of solder path red heat at the same time, hammer of the mouth that use authentic beats solder way, in order to eliminate solder broken bits. If crackle is too long, beard section separates solder to fill, general with length of 20 ～ 30mm advisable, wait for 70mm of distance solder path to be in refrigeration to arrive when can be being felt with the hand, again below solder one paragraph. If crackle is too deep, can use multilayer the method of v, must not solder is become. 4, adhesive bonding law is with crackle of body of repair air cylinder exemple, its method is: ① keeps clear of with a thick sand paper the silver-colored pink all round break of air cylinder body and ferruginous, burnish width is 30mm, length exceeds break 30mm of two end points; ② is cut with carve of line of break of cold chisel edge wide for 3mm, deeply of 2mm " V " form chamfer, and in break two end are gotten stop crack aperture; ③ cleans break with metallic clear lotion first all round, wait for alcohol of the reoccupy after working to be swabbed; ④ allocates agriculture machinery a glue; The glue liquid that ⑤ uses mix up first fill stops crack Kong He " V " form chamfer, be in of groove all round go up with the dacron cloth that has had beforehand (wide 20mm, long exceed fluid of the glue on besmear of interstitial length 10mm) , stick list on break, be in the place with original serious leakage, stick the 2nd list with same method, be in finally of list outside fluid of glue of layer of Tu Yi of again even ground. Via such processing, the engine after 24 hours can be thrown use. If be in winter, to accelerate the solidify rate that sticks gum, want to hot water of the infuse inside cistern, make airframe maintains higher temperature. CNC Milling CNC Machining
