Isikhuntaidlala indima ebaluleke kakhulu embonini yesimanje, futhi izinga layo linquma ngokuqondile ikhwalithi yomkhiqizo.Ukuthuthukisa impilo yesevisi kanye nokunemba kweisikhuntakanye nokunciphisa umjikelezo wokukhiqiza isikhunta yizinkinga zobuchwepheshe izinkampani eziningi ezidinga ukuzixazulula ngokushesha.Kodwa-ke, izindlela zokuhluleka ezifana nokuwa, ukuguqulwa, ukuguga, ngisho nokuphuka kuvame ukwenzeka ngesikhathi sokusetshenziswa.isikhunta.Ngakho-ke namuhla, umhleli uzokunikeza isingeniso sezindlela ezine zokulungisa isikhunta, ake sibheke.
Ukulungiswa kwe-welding ye-Argon arc
Ukushisela kwenziwa kusetshenziswa i-arc evuthayo phakathi kwentambo yokushisela eqhubekayo kanye nendawo yokusebenza njengomthombo wokushisa, kanye ne-arc evikelekile yegesi efafazwe kusukela kubhobho lethoshi lokushisela.Njengamanje, i-argon arc welding iyindlela evame ukusetshenziswa, engasetshenziswa ezinsimbi eziningi ezinkulu, kuhlanganise ne-carbon steel ne-alloy steel.I-MIG yokushisela ilungele insimbi engagqwali, i-aluminium, i-magnesium, ithusi, i-titanium, i-zirconium ne-nickel alloys.Ngenxa yentengo yayo ephansi, isetshenziswa kabanzi ukulungisa isikhunta.Kodwa-ke, inobubi obufana nokushisa okukhulu kwe-welding endaweni ethintekile kanye namalunga amakhulu e-solder.Ukulungiswa kwesikhunta okunembayo kuye kwathathelwa indawo kancane kancane yi-laser welding.
Ukulungiswa komshini wokulungisa isikhunta
Isikhuntaumshini wokukhanda umshini wobuchwepheshe obuphezulu ukulungisa ukugqokwa kwesikhunta kanye nokukhubazeka kokucubungula.Umshini wokulungisa isikhunta uqinisa isikhunta ukuze sibe nempilo ende kanye nezinzuzo ezinhle zezomnotho.Ama-alloys asekelwe ku-iron ahlukahlukene (i-carbon steel, i-alloy iron, i-cast iron), ama-alloys asekelwe ku-nickel nezinye izinto zensimbi angasetshenziswa ukuqinisa nokulungisa ubuso bezibungu nezinto zokusebenza, futhi kwandise kakhulu impilo yesevisi.
1. Isimiso somshini wokulungisa isikhunta
Isebenzisa umgomo wokukhishwa kwenhlansi kagesi ye-high-frequency ukulungisa ukonakala okungaphezulu nokuguga kwensimbi.isikhuntangokushisela okungaphezulu kwe-thermal endaweni yokusebenza.Isici esiyinhloko ukuthi indawo ethintekile ukushisa incane, isikhunta ngeke sikhubazekile ngemva kokulungiswa, ngaphandle kwe-annealing, akukho ukugxila kokucindezeleka, futhi akukho Ama-Cracks avelayo ukuze aqinisekise ubuqotho besikhunta;ingasetshenziswa futhi ukuqinisa ubuso bomsebenzi wesikhunta ukuze ihlangabezane nezidingo zokusebenza zokumelana nokugqokwa kwesikhunta, ukumelana nokushisa, nokumelana nokugqwala.
2. Ububanzi besicelo
Umshini wokukhanda u-Die ungasetshenziswa emishinini, emotweni, embonini ekhanyayo, ezintweni zikagesi zasendlini, ezimbonini zikaphethiloli, ezimbonini zamakhemikhali nezikagesi, ukuze kukhishwe ukushisa okushisayo.isikhunta, amathuluzi efilimu ye-extrusion efudumele, isikhunta esishisayo sokubumba, ama-rolls nezingxenye eziyinhloko ukulungisa kanye nokwelashwa kokuqinisa indawo.
Isibonelo, umshini wokulungisa izinhlansi zikagesi wohlobo lwe-ESD-05 ungasetshenziswa ukulungisa isikhunta somjovo sokuguga, imihuzuko nokuklwebheka, kanye nokulungisa ukugqwala, ukuwa kanye nokulimala kwezikhunta ezifayo njenge-zinc-aluminium die- ukuphonsa isikhunta.Amandla omshini angu-900W, i-voltage yokufaka i-AC220V, i-frequency ingu-50~500Hz, ububanzi be-voltage ngu-20~100V, kanti amaphesenti okukhiphayo ngu-10% ~ 100%.
Ukulungisa ibhulashi lokucwenga
Ubuchwepheshe bokucwenga ibhulashi busebenzisa idivayisi ekhethekile kagesi ye-DC.Isigxobo esihle somthombo wamandla sixhunywe epeni lokucwenga njenge-anode ngesikhathi se-brush plating;isigxobo esingesihle sokunikezwa kwamandla sixhunywe ku-workpiece njenge-cathode ngesikhathi se-brush plating.Ipeni lokucwenga livamise ukusebenzisa amabhlogo amahle e-graphite ahlanzekile njenge-anode material, i-graphite block isongwe ngokotini kanye nomkhono we-polyester ongagqoki kakotini.
Lapho usebenza, umhlangano wokuhlinzekwa kwamandla ulungiswa ku-voltage efanelekile, futhi ipeni lokucwenga eligcwele isisombululo se-plating lihanjiswa ngesivinini esithile esihlobene endaweni yokuxhumana yobuso bomsebenzi olungisiwe.Ama-ion ensimbi esixazululweni sokucwenga asakazeka endaweni yokusebenza ngaphansi kwesenzo samandla kagesi.Phezulu, ama-electron atholakala phezulu ancishiswa abe ama-athomu ensimbi, ukuze lawa ma-athomu ensimbi afakwe futhi acwebezeliswe ukuze akhe uqweqwe, okungukuthi, ukuthola ungqimba oludingekayo lokubeka umfaniswano endaweni yokusebenza yesikhunta sepulasitiki. zilungiswe.
Umshini we-Plasma Surfacing, umshini wokushisela we-plasma spray, ukulungiswa kwe-shaft ebusweni
Ukulungiswa kwe-laser ebusweni
I-laser welding iwukushisela lapho i-laser beam isetshenziswa khona njengomthombo wokushisa ngokugxila emfudlaneni we-photon we-monochromatic ohlangene wamandla aphezulu.Le ndlela yokushisela ngokuvamile ihlanganisa amandla aqhubekayo we-laser welding kanye ne-pulsed power laser welding.Inzuzo ye-laser welding ukuthi ayidingi ukwenziwa endaweni engenalutho, kodwa okubi ukuthi amandla angenayo awanamandla njenge-electron beam welding.Ukulawulwa kwamandla okunembile kungenziwa ngesikhathi sokushiswa kwe-laser, ukuze ukushiselwa kwamadivayisi anembile kufezeke.Ingasetshenziswa ezinsimbi eziningi, ikakhulukazi ukuxazulula ukushisela kwezinye izinsimbi okunzima ukushisela nezinsimbi ezingafani.Isetshenziswe kabanziisikhuntaukulungisa.
Ubuchwepheshe be-Laser cladding
Ubuchwepheshe be-laser surface cladding ukushisisa ngokushesha futhi kuncibilike i-alloy powder noma i-ceramic powder kanye nengaphezulu le-substrate ngaphansi kwesenzo se-laser beam.Ngemuva kokususwa kwe-beam, ukupholisa okuzithokozisayo kwakha ukumbozwa kwendawo enezinga eliphansi kakhulu lokuhlanjululwa kanye nenhlanganisela ye-metallurgical ne-substrate material., Ukuze kuthuthukiswe ngokuphawulekayo ingaphezulu le-substrate abrasion resistance, ukumelana nokugqwala, ukumelana nokushisa, ukumelana ne-oxidation kanye nezici zikagesi zendlela yokuqinisa indawo.
Isibonelo, ngemuva kwe-carbon-tungsten laser cladding yensimbi engu-60#, ubulukhuni bungafika ku-2200HV noma ngaphezulu, futhi ukumelana nokugqokwa cishe izikhathi ezingu-20 kunesisekelo esingu-60# sensimbi.Ngemuva kwe-laser cladding CoCrSiB alloy ebusweni bensimbi ye-Q235, ukumelana nokugqwala kanye nokumelana nokugqwala kokufuthwa kwelangabi kwaqhathaniswa, futhi kwatholakala ukuthi ukumelana nokugqwala kwangaphambili kwakuphakeme kakhulu kunokwakamuva.
I-Laser cladding ingahlukaniswa ngezigaba ezimbili ngokuya ngezinqubo ezahlukene zokuphakela impushana: indlela yokusetha kabusha impushana kanye nendlela yokuphakela impushana evumelanisiwe.Imiphumela yalezi zindlela ezimbili iyafana.Indlela yokondla i-powder synchronous inokulawula okuzenzakalelayo okuzenzakalelayo, izinga eliphezulu lokumunca amandla e-laser, azikho izimbotshana zangaphakathi, ikakhulukazi i-cermet yokuvala, engathuthukisa kakhulu ukusebenza kwe-anti-cracking ye-cladding layer, ukuze isigaba esiqinile se-ceramic sibe Izinzuzo zeyunifomu. ukusatshalaliswa kwesendlalelo sokuvala.
