Umngundoidlala indima ebaluleke kakhulu kushishino lwanamhlanje, kwaye umgangatho wayo umisela ngokuthe ngqo umgangatho wemveliso. Ukuphucula ubomi benkonzo kunye nokuchaneka kwayoumngundokunye nokunciphisa umjikelo wokwenziwa kwesikhunta ziingxaki zobugcisa ekufuneka zisombululwe ngokukhawuleza ziinkampani ezininzi. Nangona kunjalo, iindlela zokungaphumeleli ezifana nokuwa, ukuguqulwa, ukuguguleka, kwanokuqhekeka zihlala zenzeka ngexesha lokusetyenziswa kweumngundo.Ngoko ke namhlanje, umhleli uza kukunika intshayelelo kwiindlela ezine zokulungisa ukungunda, makhe sijonge.
Ukulungiswa kokuwelda kwe-argon arc
Ukuwelda kwenziwa ngokusebenzisa i-arc evuthayo phakathi kwentambo yokuwelda exhaswa rhoqo kunye nesixhobo somsebenzi njengomthombo wobushushu, kunye ne-arc ekhuselweyo yegesi etshizwa kwi-nozzle yetotshi yokuwelda. Okwangoku, ukuwelda kwe-argon arc yindlela esetyenziswa kakhulu, engasetyenziswa kwiintsimbi ezininzi ezinkulu, kubandakanya intsimbi yekhabhoni kunye nentsimbi ye-alloy. Ukuwelda kwe-MIG kufanelekile kwintsimbi engatyiwayo, i-aluminium, i-magnesium, i-copper, i-titanium, i-zirconium kunye ne-nickel alloys. Ngenxa yexabiso layo eliphantsi, isetyenziswa kakhulu ekuwelding ukulungisa isikhunta. Nangona kunjalo, ineengxaki ezifana nendawo enkulu echaphazelekileyo kubushushu bokuwelda kunye namalungu amakhulu e-solder. Ukulungiswa kwesikhunta esichanekileyo kuye kwathatyathelwa indawo kancinci yi-laser welding.
Ukulungiswa komatshini wokulungisa isikhunta
UmngundoUmatshini wokulungisa sisixhobo sobuchwepheshe obuphezulu sokulungisa ukuguguleka komphezulu wesikhunta kunye neziphene zokucubungula. Umatshini wokulungisa isikhunta uyomeleza isikhunta ukuze sibe nobomi obude kunye neenzuzo ezilungileyo kwezoqoqosho. Ii-alloys ezahlukeneyo ezisekelwe kwisinyithi (intsimbi yekhabhoni, intsimbi ye-alloy, intsimbi ephosiweyo), ii-alloys ezisekelwe kwi-nickel kunye nezinye izinto zesinyithi zingasetyenziselwa ukuqinisa nokulungisa umphezulu wesikhunta kunye nezinto zokusebenza, kwaye zonyuse kakhulu ubomi benkonzo.
1. Umgaqo womatshini wokulungisa isikhunta
Isebenzisa umgaqo wokukhupha i-spark yombane ephuma rhoqo ukulungisa iziphene zomphezulu kunye nokuguguleka kwesinyithi.umngundongokuwelda umphezulu ongatshisi ubushushu kwindawo yokusebenza. Uphawu oluphambili kukuba indawo echaphazelekileyo bubushushu incinci, isikhunta asiyi konakala emva kokulungiswa, ngaphandle kokutsalwa, akukho xinzelelo, kwaye akukho ziqhekeko ezibonakalayo ukuqinisekisa ukuthembeka kwesikhunta; ingasetyenziselwa ukuqinisa umphezulu wesikhunta ukuze ihlangabezane neemfuno zokusebenza zokumelana nokuguguleka kwesikhunta, ukumelana nobushushu, kunye nokumelana nokugqwala.
2. Ububanzi besicelo
Umatshini wokulungisa iidayi ungasetyenziswa koomatshini, kwiimoto, kushishino lokukhanya, kwizixhobo zasekhaya, kumashishini epetroleum, kwiikhemikhali nakumbane, ukuze kukhutshwe izinto ezishushu.iimbumba, izixhobo zefilimu yokukhupha izinto ezifudumeleyo, ii-hot forging molds, ukulungiswa kwee-rolls kunye neendawo ezibalulekileyo kunye nonyango lokuqinisa umphezulu.
Umzekelo, umatshini wokulungisa i-spark surfacing yohlobo lwe-ESD-05 ungasetyenziselwa ukulungisa ii-injection molds zokuguguleka, imikrwelo kunye nemikrwelo, kunye nokulungisa umhlwa, ukuwa kunye nomonakalo wee-die-casting molds ezifana nee-zinc-aluminium die-casting molds. Amandla omatshini yi-900W, i-input voltage yi-AC220V, i-frequency yi-50~500Hz, uluhlu lwe-voltage yi-20~100V, kwaye ipesenti yemveliso yi-10%~100%.
Ukulungiswa kweepleyiti zebrashi
Itekhnoloji yokugquma ibrashi isebenzisa isixhobo esikhethekileyo sombane se-DC. Ipali elungileyo yombane iqhagamshelwe kwipeni yokugquma njenge-anode ngexesha lokugquma ibrashi; ipali engalunganga yombane iqhagamshelwe kwindawo yokusebenza njenge-cathode ngexesha lokugquma ibrashi. Ipeni yokugquma idla ngokusebenzisa iibhloko zegrafiti ezicocekileyo kakhulu njengezinto ze-anode, ibhloko yegrafiti isongelwe ngekotoni kunye nesingxobo sekotoni sepolyester esingagugiyo.
Xa usebenza, indibano yombane ilungiswa kwi-voltage efanelekileyo, kwaye ipeni yokugquma egcwele isisombululo sokugquma ishukunyiswa ngesantya esithile kwindawo yokunxibelelana yomphezulu wesixhobo sokugquma esilungisiweyo. Ii-ion zesinyithi kwisisombululo sokugquma ziyasasazeka kwindawo yokusebenza phantsi kwesenzo samandla ombane. Phezu komphezulu, ii-elektroni ezifunyenwe kumphezulu ziyancitshiswa zibe zii-athomu zesinyithi, ukuze ezi athomu zesinyithi zibekwe kwaye zikrwelwe ukuze zenze i-coating, oko kukuthi, ukufumana umaleko wokubeka ofanayo kumphezulu wokusebenza weplastiki yokubumba oza kulungiswa.
Umatshini wokugquma ngeplasma, umatshini wokugquma ngeplasma, ukulungiswa komphezulu weshaft
Ukulungiswa komphezulu welaser
Ukuwelda nge-laser kukuwelda apho umqadi we-laser usetyenziswa njengomthombo wobushushu ngokugxila kumsinga we-photon ohambelanayo onamandla aphezulu. Le ndlela yokuwelda idla ngokuquka ukuwelda nge-laser enamandla aqhubekayo kunye nokuwelda nge-laser amandla ashukumayo. Inzuzo yokuwelda nge-laser kukuba akufuneki yenziwe kwi-vacuum, kodwa ingxaki kukuba amandla angena ngaphakathi awanamandla njenge-electron beam welding. Ulawulo lwamandla oluchanekileyo lunokwenziwa ngexesha lokuwelda nge-laser, ukuze ukuwelda kwezixhobo ezichanekileyo kufezekiswe. Ingasetyenziswa kwiintsimbi ezininzi, ngakumbi ukusombulula ukuwelda kwezinye iintsimbi ezinzima ukuwelda kunye neentsimbi ezahlukeneyo. Isetyenziswe kakhuluumngundoukulungiswa.
Itekhnoloji yokugquma nge-laser
Itekhnoloji yokugquma umphezulu welaser kukufudumeza ngokukhawuleza nokunyibilikisa umgubo we-alloy okanye umgubo we-ceramic kunye nomphezulu we-substrate phantsi kwesenzo se-laser beam. Emva kokuba umqadi ususiwe, ukupholisa okuzivuselelayo kwenza uphahla lomphezulu olunesantya esiphantsi kakhulu sokunyibilikisa kunye nokudibanisa kwe-metallurgical kunye nezinto ze-substrate. , Ukuze kuphuculwe kakhulu umphezulu we-substrate ukuxhathisa ukurhawuzelelwa, ukumelana nokugqwala, ukumelana nobushushu, ukumelana ne-oxidation kunye neempawu zombane zendlela yokuqinisa umphezulu.
Umzekelo, emva kokufakwa kwe-carbon-tungsten laser cladding yentsimbi engama-60#, ubunzima bufikelela kwi-2200HV nangaphezulu, kwaye ukumelana nokuguguleka kumalunga nama-20 kunokwentsimbi esisiseko engama-60#. Emva kokufakwa kwe-laser cladding i-CoCrSiB alloy kumphezulu wentsimbi ye-Q235, ukumelana nokuguguleka kunye nokumelana nokuguguleka kokutshiza ilangabi kwathelekiswa, kwaye kwafunyaniswa ukuba ukumelana nokuguguleka kweyokuqala kwakuphezulu kakhulu kunokweyokugqibela.
Ukugquma nge-laser kunokwahlulwahlulwa kube ngamacandelo amabini ngokweenkqubo ezahlukeneyo zokutyisa umgubo: indlela emiselweyo yomgubo kunye nendlela yokondla umgubo ehambelanayo. Iziphumo zezi ndlela zimbini ziyafana. Indlela yokondla umgubo ehambelanayo inolawulo oluzenzekelayo olulula, izinga eliphezulu lokufunxwa kwamandla e-laser, akukho mingxunya yangaphakathi, ngakumbi i-cladding cermet, enokuphucula kakhulu ukusebenza kokuchasana nokuqhekeka komaleko wokugquma, ukuze isigaba se-ceramic esiqinileyo sibe neengenelo zokusasazwa okufanayo komaleko wokugquma.
