Ngundoidlala indima ebaluleke kakhulu kushishino lwanamhlanje, kwaye umgangatho wayo umisela ngokuthe ngqo umgangatho wemveliso.Ukuphucula ubomi benkonzo kunye nokuchaneka kwengundokunye nokunciphisa umjikelo wokwenziwa komngundo ziingxaki zobugcisa ekufuneka iinkampani ezininzi zizisombulule ngokukhawuleza.Nangona kunjalo, iindlela zokungaphumeleli ezinje ngokuwa, ukuguqulwa, ukunxiba, kunye nokuqhekeka zihlala zisenzeka ngexesha lokusetyenziswa.ngundo.Ke namhlanje, umhleli uya kukunika intshayelelo kwiindlela ezine zokulungisa umngundo, makhe sijonge.
Argon arc ukulungiswa welding
I-welding iqhutywa ngokusebenzisa i-arc evuthayo phakathi kocingo lwe-welding oluqhubekayo kunye ne-workpiece njengomthombo wobushushu, kunye ne-arc ekhuselekileyo yegesi efafazwe kwi-nozzle yetotshi ye-welding.Okwangoku, i-argon arc welding yindlela esetyenziswa ngokuqhelekileyo, enokuthi isetyenziswe kwiintsimbi ezininzi ezinkulu, kuquka i-carbon steel kunye ne-alloy steel.I-MIG welding ifanelekile kwinsimbi engenasici, i-aluminium, i-magnesium, ubhedu, i-titanium, i-zirconium kunye ne-nickel alloys.Ngenxa yexabiso layo eliphantsi, isetyenziselwa ngokubanzi ukulungiswa kwe-welding ye-mold.Nangona kunjalo, inezingeloncedo ezifana nobushushu obukhulu be-welding indawo echaphazelekayo kunye namalungu amakhulu e-solder.Ukulungiswa kokungunda ngokuchanekileyo kuye kwathatyathelwa indawo yi-laser welding.
Ukulungiswa komatshini wokulungisa umngundo
Ngundoumatshini wokulungisa sisixhobo sobuchwephesha obuphezulu ukulungisa ukunxitywa komphezulu womngundo kunye neziphene zokulungisa.Umatshini wokulungisa umngundo womeleza isikhunta ukuba sibe nobomi obude kunye neenzuzo ezilungileyo zezoqoqosho.Ii-alloys ezisekelwe kwi-iron (i-carbon steel, i-alloy iron, i-iron cast), i-alloys esekelwe kwi-nickel kunye nezinye izinto zetsimbi zingasetyenziselwa ukuqinisa kunye nokulungiswa kwendawo yokubumba kunye nezixhobo zokusebenza, kunye nokwandisa kakhulu ubomi benkonzo.
1. Umgaqo womatshini wokulungisa isikhunta
Isebenzisa umgaqo wokukhutshwa kwentlantsi yombane ephezulu-frequency ukulungisa iziphene zomhlaba kunye nokunxiba kwentsimbi.ngundonge-non-thermal phezu kwe-welding kwi-workpiece.Inqaku eliphambili kukuba indawo echaphazelekayo yokushisa incinci, isikhunta asiyi kuphazamiseka emva kokulungiswa, ngaphandle kokuqhawula, akukho xinzelelo loxinzelelo, kwaye akukho Amaqhekeza abonakala aqinisekisa ukunyaniseka kwesikhunta;ingasetyenziselwa ukomeleza umphezulu womsebenzi wokungunda ukuhlangabezana neemfuno zokusebenza zokunganyangeki kokungunda, ukuxhathisa ubushushu, kunye nokumelana nokubola.
2. Ubungakanani besicelo
Umatshini wokulungisa ukufa unokusetyenziswa koomatshini, iimoto, ishishini elikhanyayo, izixhobo zasekhaya, i-petroleum, iikhemikhali kunye namashishini amandla ombane, kumashishini ashushu.ukungunda, izixhobo zefilimu ezifudumeleyo ze-extrusion, iimbumba ezitshisayo zokubumba, ii-rolls kunye neendawo eziphambili zokulungisa kunye nonyango lokuqinisa umphezulu.
Umzekelo, uhlobo lwe-ESD-05 umatshini wokulungisa intlantsi yombane yombane unokusetyenziselwa ukulungisa iinaliti zokuguga, imivumbo kunye nemikrwelo, kunye nokulungisa umhlwa, ukuwa kunye nomonakalo wokubumba okuphosa ukufa okufana ne-zinc-aluminium die- ukubumba imingundo.Amandla omatshini yi-900W, i-voltage yegalelo yi-AC220V, i-frequency yi-50 ~ 500Hz, uluhlu lwe-voltage yi-20 ~ 100V, kwaye ipesenti yokuphuma yi-10% ~ 100%.
Ukulungisa ibrashi yeplating
Itekhnoloji yokucwenga ibrashi isebenzisa isixhobo esikhethekileyo sobonelelo lwamandla eDC.Ipali echanekileyo yonikezelo lwamandla idityaniswe kwipeni yokucoca njenge-anode ngexesha le-brush plating;ipali engalunganga yonikezelo lwamandla iqhagamshelwe kwindawo yokusebenza njengecathode ngexesha lokufakwa kwebrashi.Ipeni yokucwenga ngokuqhelekileyo isebenzisa iibhloko eziphezulu zegraphite ezicocekileyo njengezinto ze-anode, ibhloko yegraphite isongelwe ngomqhaphu kunye nomkhono wepolyester ongagugiyo.
Xa usebenza, indibano yokubonelela ngombane ihlengahlengiswa kwi-voltage efanelekileyo, kunye nepeni yokucwenga egcwele isisombululo sokucoca ishukunyiswa ngesantya esithile esihambelanayo kwindawo yokudibanisa yobuso bomsebenzi olungisiweyo.Iiyoni zetsimbi kwisisombululo se-plating zisasazeka kwi-workpiece phantsi kwesenzo samandla ombane.Kumphezulu, ii-electron ezifunyenwe kumphezulu ziyancitshiswa zibe athom zesinyithi, ukuze ezi athom zentsimbi zifakwe kwaye zenziwe ngekristale ukuze zenze i-coating, oko kukuthi, ukufumana i-uniform deposition layer kwi-workwork ye-plastic mold cavity. zilungiswe.
Umatshini wePlasma ojonga phezulu, umatshini wokutshiza weplasma, ukulungiswa kweshaft ebusweni
Ukulungiswa komphezulu weLaser
I-laser welding yi-welding apho i-laser beam isetyenziswe njengomthombo wokushisa ngokugxila kumbane ophezulu ohambelana ne-monochromatic photon.Le ndlela yokuwelda idla ngokubandakanya ukuwelda kwamandla aqhubekayo kunye ne-pulsed power laser welding.Inzuzo ye-laser welding kukuba akufuneki ukuba iqhutywe kwi-vacuum, kodwa into engalunganga kukuba amandla okungena anamandla njenge-electron beam welding.Ulawulo oluchanekileyo lwamandla lunokwenziwa ngexesha le-laser welding, ukwenzela ukuba i-welding yezixhobo ezichanekileyo ifezekiswe.Ingafakwa kwiintsimbi ezininzi, ngakumbi ukusombulula ukuwelda kwesinyithi esinzima uku-weld kunye neentsimbi ezingafaniyo.Isetyenziswe ngokubanzingundoukulungisa.
Itekhnoloji yokufakelwa kweLaser
I-laser surface cladding technology kukutshisa ngokukhawuleza kwaye kunyibilike i-alloy powder okanye i-ceramic powder kunye nomphezulu we-substrate phantsi kwesenzo se-laser beam.Emva kokuba i-boam isusiwe, ukupholisa okuzithandayo kubumba i-coating surface kunye neqondo eliphantsi kakhulu lokuhlanjululwa kunye nokudibanisa i-metallurgical kunye ne-substrate material., Ukuze kuphuculwe kakhulu umgangatho we-substrate abrasion resistance, ukuxhathisa kwe-corrosion, ukumelana nobushushu, ukuxhathisa i-oxidation kunye neempawu zombane zendlela yokomeleza umphezulu.
Umzekelo, emva kwe-carbon-tungsten laser cladding ye-60 # yentsimbi, ubunzima bufikelela kwi-2200HV okanye ngaphezulu, kwaye ukuxhathisa ukunxiba malunga namaxesha angama-20 kwisiseko se-60 # yentsimbi.Emva kwe-laser cladding CoCrSiB ialloy kumphezulu wentsimbi ye-Q235, ukuxhathisa ukunxitywa kunye nokumelana nokugqwala kokutshiza kwedangatye kwathelekiswa, kwaye kwafunyaniswa ukuba ukuxhathisa kwe-corrosion yangaphambili kwakuphezulu kakhulu kunoko kwamva.
I-Laser cladding inokohlulwa ibe ziindidi ezimbini ngokweenkqubo ezahlukeneyo zokutyisa umgubo: indlela yokusetwa kwangaphambili komgubo kunye ne-synchronous powder feeding method.Iziphumo zezi ndlela zimbini ziyafana.I-synchronous powder feeding method inolawulo olulula oluzenzekelayo, izinga eliphezulu lokufunxa amandla e-laser, akukho pores yangaphakathi, ngakumbi i-cermet yokugubungela, enokuphucula kakhulu ukusebenza kwe-anti-cracking ye-cladding layer, ukwenzela ukuba isigaba esinzima se-ceramic sibe neenzuzo zeyunifomu. usasazo kwileya yokugquma.
