Xa abantu abaninzi besiva 'i-carbon steel investment casting', bakhawuleza bacinge ngokuchaneka kunye nomphezulu ogudileyo. Yinyani leyo, kodwa kukwalapho imbono yokuqala engalunganga ilele khona. Owona mceli mngeni ayikokufikelela nje kwisiphelo esihle sokuphoswa; ilawula izinto eziguquguqukayo zendalo kwimathiriyeli ngokwayo-amazinga acuthekayo, impendulo yonyango lobushushu, ukubanakho ukuphosa iziphene ezikhethekileyo kwiintsimbi zekhabhoni xa kuthelekiswa, yithi, engenabala. Yinkqubo apho ithiyori efanelekileyo ephepheni ihlala idibana nobunyani bomgangatho wesiseko.
Ucelomngeni olungundoqo: Konke kumalunga noLawulo
Masithethe ngeqokobhe. Kwintsimbi yekhabhoni, ngakumbi amabanga aphantsi ukuya kwaphakathi, ukukwazi ukutyhutyha inkqubo yeqokobhe kunye namandla ashushu abaluleke kakhulu. Udinga iqokobhe elinokumelana namaqondo obushushu aphezulu okugalelwa kwentsimbi ngaphandle kokubotshwa, kodwa nelinye elivumela iigesi ukuba zibaleke. Ndizibonile iiprojekthi zisilela ngenxa yokuba iqokobhe belixinene kakhulu, nto leyo ekhokelela kwirhasi porosity ivaleleke ngaphantsi komphezulu wento ebonakala ngathi kukuphosa okugqibeleleyo. Sisenzo sokulinganisa. Inkampani efumana oku ngokufanelekileyo, njengaye Qingdao Qiangsenyuan Technology Co., Ltd.(QSY), isebenzise amashumi eminyaka aloo mava akhethekileyo. Ungayibona indlela yabo yokudibanisa iqokobhe ngundo ukuphosa kwaye utyalo mali kwiqonga labo https://www.tsingtaocnc.com. Ayikokuba nezixhobo nje kuphela; imalunga nokwazi ukuba yeyiphi iresiphi yeqokobhe esebenzela intsimbi ye-1020 xa ithelekiswa ne-1045.
Esinye isiqingatha se-equation yintsimbi ngokwayo. Ukuziqhelanisa ne-Deoxidation yinto engafane ixoxwe ngaphandle kwevenkile enyibilikayo. Ngentsimbi ye-carbon, uyibulala njani intsimbi kwi-ladle-i-aluminium, i-silicon, i-calcium? Kancinci kakhulu, ubeka umngcipheko wepinholes. Kakhulu, udala ukubandakanywa okungeyiyo okwentsimbi enokonakalisa umatshini kamva. Apha kulapho imvelaphi ye-QSY yeminyaka engama-30 ayikhankanyi nje umgca wokuthengisa; yincwadi yokubhala yeeresiphi zokunyibilika kunye neziphumo zamacandelo ahlukeneyo kunye nobunzima.
Kwaye ke kukho ipateni. Kwiindawo ezintsonkothileyo zentsimbi yekhabhoni, isibonelelo soyilo loyilo lwewax asilonani elinye. Itshintsha kunye nobukhulu becandelo. Ihabhu etyebileyo kunye neflange encinci kwinqanaba elifanayo liya kucutheka ngamaxabiso ahlukeneyo. Oku sikufunde kabuhlungu kwiprojekthi yokwakhiwa kwezixhobo zakwangoko.

Ngoku, sisebenzisa imithetho yokucutha emodareyithiweyo esekwe kwidatha yembali evela kwiijometri ezifanayo, olulo kanye uhlobo lolwazi olucwangcisiweyo oluqokelelwa ngumsebenzi wexesha elide.
Apho Inkqubo ingqina ukufaneleka kwayo
Ngoko apho kwenzeka i-carbon steel investment casting yenza ingqiqo engenakuphikiswa? Jonga amacandelo ekufuneka omelele, anganxibi kangako, kodwa aphinde antsonkothe ngobume kwaye apho umatshini osuka kwisitokhwe sebha kuya kuba yinkcitho engavumelekanga. Cinga ngemizimba yevalvu yehydraulic, izikhewu zezixhobo ezincinci, okanye izixhobo ezithile zezolimo. Ubunakho obusondeleyo bobume bomnatha bugcina isixa esikhulu semathiriyeli ekrwada kunye nexesha lomatshini elilandelayo. Ngokomzekelo, ukuvelisa ingalo ye-lever eneempawu ezininzi ezine-angle kunye neepaseji zangaphakathi njengokuphosa kunokushiya kuphela iijenali ezithwele kunye nemicu ukuba yenziwe ngoomatshini.
Kodwa utyalo-mali egameni likwasisilumkiso seendleko. Kwizinto ezilula, ezinqabileyo zentsimbi yekhabhoni, ukuphosa isanti phantse kusoloko kunoqoqosho. Indawo emnandi inzima. Ndikhumbula iprojekthi yendibano yesiqhelo yokudibanisa esetyenziswa koomatshini abanzima. Inxalenye yayineefom ezininzi ze-cylindrical intersecting kunye nee-angles ezingekho-standard. Ukuyilungisa kwibhloko eqinileyo kucatshulwe kwinani leenkwenkwezi ngenxa yenkunkuma yezinto eziphathekayo kunye nexesha lokucwangcisa. Ngokusasazwa kotyalo-mali, sivelise eyona fomu ingundoqo enesitokhwe esincinci soomatshini kubuso obubalulekileyo. Ixabiso le-per-part laliphezulu kune-casting elula, kodwa ixabiso elipheleleyo lokufika, kubandakanywa nomatshini, malunga ne-40% ephantsi. Lolo lubalo lokwenyani.
Inqanaba elibalulekileyo, elihlala lingahoywa, luhlolo lokuqala lwenqaku. Kwi-carbon steel casting entsha, kufuneka uqinisekise kungekuphela nje imilinganiselo kodwa kunye nokuthembeka kwangaphakathi. Sihlala sidibanisa ingxelo yenqaku lokuqala kunye novavanyo lokusika. Uncama ukuphosa okunye, ukwahlula kwiindawo ezibalulekileyo (ngokuqhelekileyo awona macandelo atyebileyo kunye neendawo zokuhlangana), kwaye uyiqabe. Oku kutyhila ukwakheka kweenkozo kunye naluphi na ukuncipha okufihliweyo okanye i-porosity. Yeyona ndlela kuphela yokuqinisekisa ukuba i-gating yakho kunye nenkqubo yokunyuka iyasebenza phambi kokuba wenze imveliso yokukhanya okuluhlaza. Ukutsiba eli nyathelo kukungcakaza okunamathuba aphezulu okusilela.
I-Machining Handoff: I-Main-or-Break Interface
Kulapho umthengisi odibeneyo ebonisa ixabiso lakhe. Ukuphosa yinto enye; Ukunikela inxalenye elungiselwe indibano yenye. Iintsimbi zekhabhoni zotyalo-mali zidla ngokukhethwa ngenxa yobuchule bazo. Kodwa imeko ye-as-cast ibalulekile. Umphezulu onzima kakhulu ekupholiseni ngokukhawuleza unokunxiba izixhobo zokusika ngaphambi kwexesha. Yiyo loo nto ubudlelwane phakathi kwesiseko kunye nevenkile yomatshini kufuneka buqine. Xa bobabini bephantsi kophahla olunye, njengakwi-QSY apho badibanisa ukuphosa kunye CNC Machining, iluphu yengxelo ikhawuleza. Iqela machining ungaxelela Foundry, Le ibhetshi ibaleka shushu kwizixhobo, kwaye Foundry unako ukunyenyisa unyango ubushushu eqhelekileyo umjikelo okanye izinga lokupholisa ukuze ugalele elandelayo.
Xa sithetha ngonyango lobushushu, alufane lukhethe. Kuninzi lweekhabhoni zotyalo-mali lwentsimbi, ujonge ukuqheleka okanye umjikelo we-annealing ukwenza i-homogenize ubume benkozo kunye nokunciphisa uxinzelelo. Eli nyathelo libalulekile kuzinzo lwe-dimensional ngexesha lomatshini. Ukuba uyatsiba, inxalenye inokuhamba ngokungalindelekanga njengoko uyinqumle, ukrazula ukuphoswa kwexabiso eliphezulu emva kokuba sele utyale ixesha lokutyala kuyo. Undoqo kukungaguquguquki. Iprofayili yesithando somlilo, ixesha lokufunxa, izinga lokupholisa-kufuneka libe yibhetshi ephindaphindiweyo kwibhetshi.
Enye intloko esebenzayo kukususwa kwesango kunye nesikhuphukeli. Kwintsimbi ye-carbon, uhlala usebenzisa i-abrasive cutting okanye i-sawing. Indawo yezi ndawo zokususa ifuna ukucingelwa kwangaphambili. Awufuni i-stub yesango eshiywe kwindawo eba yindawo yokutywina ebalulekileyo okanye indawo yoxinzelelo. Isenzo esilungileyo kukuyila isango lokungena ukuze iindawo zokususa zihlale kwiindawo ezingabalulekanga okanye umphezulu oza kususwa ngoomatshini ngokupheleleyo. Oku kufuna intsebenziswano yangaphambili phakathi kwenjineli yoyilo kunye nenjineli yenkqubo yokufumana, into egudileyo xa usebenza neqabane elinobuchule bobugcisa.
IiNuances zeMathiriyeli: Ayizizo zonke iintsimbi zeCarbon ezilinganayo
Ngaphakathi kwintsapho ye-carbon steel, ukhetho lubalulekile. I-AISI 1020 ixhaphakile, inika i-weldability elungileyo kunye ne-ductility kodwa amandla aphantsi. Kwiindawo ezifuna amandla amaninzi kunye nokuchasana ngcono ngaphandle kokuya kwiintsimbi ze-alloy, i-1045 okanye i-1055 inokuchazwa. Kodwa ngomxholo wekhabhoni ephezulu kuza uvakalelo olukhulu ekuqhekekeni ngexesha lokupholisa kunye nolawulo olubaluleke ngakumbi lonyango lobushushu. Awunakutshintsha nje ipateni ye-1045 kwinkqubo eyilelwe i-1020 kwaye ulindele ukuba isebenze. Iimfuno zokutyisa zahlukile.
Sakhe sacela ukusebenzisa intsimbi enekhabhoni ephezulu kwipleyiti yokunxiba. Ulingo lokuqala lubangele iinyembezi ezishushu-iintanda ezenzeka ngelixa ukuphosa kusaqinile. Isisombululo asikokutshintsha nje isinyithi; ibandakanya ukuyilwa ngokutsha komngundo ukuba kubekho ukupholisa okufanayo kunye nokuguqula ukwakheka kweqokobhe kwiikona ezithile ukuze kuthintelwe kancinci ngexesha lokufinyela. Yayilulungiso lwenkqubo, hayi nje ukutshintshwa kwezinto. Oku kuhambelana nobuchule obunokulindela kumthengisi ofana ne-QSY, onoluhlu lwemathiriyeli olubandakanya okwahlukeneyo intsimbi kwaye ialloys ezikhethekileyo, nto leyo ethetha ukuba kuye kwafuneka basombulule ezi puzzle zesinyithi.
Enye i-nuance yi-surface decarburization. Ngexesha lonyango lobushushu, ikhabhoni inokufuduka ngaphandle komgangatho wentsimbi, ishiye ulusu oluthambileyo. Kwizicelo ezininzi, oku akungomba njengoko kucinyiwe. Kodwa kwiindawo apho umphezulu we-as-cast usebenza (njengeendawo ezithile zokunxiba), yingxaki. Ukulawula umoya kwiziko lokuphatha ubushushu okanye ukusebenzisa iingubo ezikhuselayo kuba yinxalenye yenkqubo. Ziinkcukacha eziphuma kuphela kumava okusebenza ngekhonkco lemveliso epheleleyo.
