Ubona 'intsimbi yentsimbi elahlekileyo' kwiphepha elithile kwaye ucinge 'ukuchaneka, iimilo ezintsonkothileyo, ukugqiba okuhle' - kwaye awuphazamanga. Kodwa le yinguqulelo yencwadana. Apho ifumaneka khona yokwenyani, kwaye ngokungafihlisiyo apho uninzi lwabathengisi begeneric bekhubeka, kuguqulo ukusuka kwipatheni entle yewax ukuya kwinto esebenzayo, isandi sentsimbi elungele inkonzo. Umsantsa phakathi kokuphosa kunye nokuphosa okulungileyo kulapho amashumi eminyaka eeyure zomgangatho wevenkile zibalulekile.
Umthwebeba sisiqalo nje, hayi isiphelo
Wonke umntu ugxininisa kwi-wax. Bubugcisa obubonakalayo. Kodwa isigwebo sokwenyani siqala emva kokuthotywa, xa ushiywe ngeqokobhe leceramic elingenanto. Nantso indawo embi. Indlela oyizalisa ngayo ichaza yonke into. Ukugalela intsimbi akufani nokuzalisa ibhakethi; sisiganeko esilawulwayo sobushushu. Ngeentsimbi, ngokukodwa ii-alloys eziphezulu, ifestile phakathi kokuzaliswa okucocekileyo kunye nesiphako sincinci. Ndikhe ndabona ukugalela apho iqondo lobushushu belicinywe yinto ebonakala ngathi incinci – mhlawumbi i-25°C – kwaye yazisa isiphithiphithi esikhokelele kwiziva ezingaphezulu ekungekho sixa sokusila sinokucima ngokupheleleyo. Umngundo unokuba ugqibelele, kodwa inkqubo yayingekho.
Apha kulapho ingqeqesho ye-Foundry ibonisa. Indawo efana Qingdao Qiangsenyuan Technology Co., Ltd.(QSY) ayibaleki nje umgca; bebekule nto iminyaka engaphezu kwama-30. Obo bomi bude buthetha ngesiqhelo esinobuchule. Kuthetha ukuba babone iindlela zokungaphumeleli - iqokobhe liyaqhekeka ukusuka kubushushu obukhawulezayo, ukufakwa kwi-slag, i-micro-porosity evela kwirhasi. Ubungcali babo kwi utyalo mali kwaye iinkqubo zokungunda iqokobhe asiyondawo yembumbulu; lithala leempazamo ezilungisiweyo. Awukwazi ukukhohlisa ukuba ubunzulu.
Thatha isango lokungena kunye noyilo lokunyuka. Asiyothiyori. Kumzimba wevalve entsonkothileyo esakhe sayenza kwi-316 engenastainless, ukulinganisa kokuqala kujongeka kakuhle. Kodwa ukugalelwa kokuqala kubonise ukucutheka kwindawo eshinyeneyo ukuya kumbhityi wenguqu. Ukulungiswa bekungekokongeza nje isinyithi esingaphezulu (isikhuphukeli); yayibeka ngokutsha amasango angaphakathi ukulawula indlela yokuqinisa. Kwafuneka siphinde sisebenzise umthi we-wax. Oko kulahlekile ixesha kunye nemali. Ivenkile engenalo grit yokusombulula ingxaki ingahlala ithumela iindawo ezamkelekileyo, kwaye umxhasi uya kujongana nokusilela kwangaphambi kwexesha ezantsi emgceni.
Izinto eziphathekayo zingaphezu kwenani leBanga
Ukuchaza intsimbi yekhabhoni okanye intsimbi engatyiwa sisiqalo, kodwa iphantse ibe yingozi ingacacanga. Ngaphakathi 'okungenasiphelo,' unothotho lwe-austenitic 300, uthotho lwe-martensitic 400, amabanga aphindwe kabini - ngalinye liziphatha ngendlela eyahlukileyo ngexesha nasemva kokudlala. Ubumanzi bazo, izinga lokucutheka, kunye namandla ashushu ayahluka. Galela i-304 ngathi ungagalela i-17-4 PH, kwaye uya kuba nokuqhekeka. Unyango lobushushu emva kokuphoswa lubaluleke kakhulu kwabanye, alunamsebenzi kwabanye.
QSYUluhlu lwemathiriyeli edwelisiweyo - ukusuka kwiintsimbi ezityhidiweyo kunye neentsimbi eziqhelekileyo ukuya kwi-nickel-based kunye ne-cobalt-based alloys - indixelela ukuba bayaqonda ukuba isinyithi asiyo bar esecaleni. Ezi alloys ezikhethekileyo sisilo. Zihlala zigalelwa ngenkonzo egqithisileyo: iincakuba zeinjini yomoya, iinxalenye zeathom yeekhemikhali. Ziyabiza, ngoko ke inkunkuma ibuhlungu. Ukuphosa kwabo kufuna ukhuseleko lomoya ongasebenziyo, ulawulo oluchanekileyo lwe-thermal, ngokufuthi ukunyibilika kwevacuum. Awungeni ndawo nje kule nto. Ukuba iwebhusayithi yabo, tsngtaocnc.com, ibonisa isakhono kwezi, kuthetha inqanaba leteknoloji yesithando somlilo kunye nolawulo lwenkqubo olubahlula kwi-caster ye-job-shop.
Ndikhumbula iprojekthi ebandakanya i-alloy component ye-Monel (nickel-copper). Iwax kunye neqokobhe zazingenasiphako. Ukugalelwa kwakubonakala kukuhle. Kodwa ngexesha lokunkqonkqoza kweqokobhe, sifumene ukusabela okukhulu komphezulu-uhlobo oluthile lomaleko, oxidized. Ingxaki? Ikhemikhali yokudibanisa iqokobhe ibinokungahlambuluki okuncinci okwathi kuchaphazeleke ngobundlongondlongo nickel etyhidiweyo kobo bushushu buphezulu. Siye satshintshela kokwahlukileyo, ngaphezulu kwe-inert refractory yokwaleka kwiileya eziphambili. Ingxaki yasonjululwa, kodwa ngenxa yokuba sinenkxaso ye-metallurgical ukuyixilonga. Ivenkile eyenza i-carbon steel yayiza kulahleka ngokupheleleyo.
I-Fish isenziwa kwi-Rugh
Enye ingcamango ephosakeleyo eqhelekileyo: i-wax elahlekileyo ivelisa inxalenye ekulungele ukusetyenziswa. Kunqabile ukuba yinyani. Into eyivelisayo yinxalenye enomgangatho olungileyo wokuphoswa, rhoqo malunga ne-125 Ra microinches okanye ngcono. Kodwa 'ukulungele' kuxhomekeke kwisicelo. Ngaba isibiyeli sokuhombisa? Mhlawumbi ukugqabhuka kwentsimbi yeglasi kwanele. Ngaba yibhloko ephindaphindwayo yehydraulic? Ngoku ufuna imiphezulu yokutywina echanekileyo, izibuko ezinemisonto, imingxuma yokufaka. Kulapho okudityanisiweyo CNC Machining Ikhono liba yinto engenakuxoxisana.
Le yintsebenziswano enikezelwa ngumnikezeli wenkonzo epheleleyo. QSY ukudibanisa ukuphosa kunye nomatshini phantsi kophahla olunye yeyona nto iphambili yolungiselelo kunye nomgangatho woncedo. Banokuyila ukuphosa kunye nesitokhwe somatshini engqondweni, ukuqonda ukuba inxalenye iya kulungiswa njani, apho akhona amanqaku edatha. Bayiphosa, bayiphathe ubushushu (ukuba kuyimfuneko), emva koko bayitshise kwindawo enye. Oku kulawula lonke ikhonkco. Ndikhe ndajongana nephupha elibi lokuthumela i-castings eluhlaza kwivenkile yomatshini eyahlukileyo, ukufumana kuphela ukugqwetheka okuncinci okanye ukubandakanywa kwesanti efihliweyo eyonakalisa isixhobo ngexesha lokomba. Umdlalo wetyala uyaqala. Indlu edibeneyo ingumnini wayo yonke inkqubo.
Ukwenziwa kwentsimbi yentsimbi, ngakumbi ukusuka kwi iwax elahlekileyo inkqubo, ineemfuno zayo. Isixhobo sinokuba namabala obunzima obuguquguqukayo ukuba ukupholisa bekungafani ngokugqibeleleyo. Umchwephesha olungileyo, osebenza kunye neqela le-Foundry, unokulungelelanisa ukutya kunye nesantya. Babelana ngolwazi. Loo loop yengxelo yangaphakathi ayibonakali kumxhasi kodwa ixabiseke kakhulu ukuhambelana.
Xa Izinto Ezintsonkothileyo Zidibana Zisebenza
I-classic showcase ye-wax elahlekileyo i-ornate, i-lace-like geometry. Kwaye iyagqwesa apho. Kodwa uvavanyo olunzima yinxalenye ebonakala ilula kodwa inobunzima obufihliweyo. Cinga nge-impeller yempompo ene-vanes ecekethekileyo, egobileyo kunye noyilo olufihliweyo. Ifuna imiphezulu yoxinzelelo lwehydraulic yangaphakathi egudileyo ukunciphisa isiphithiphithi. Ifuna ibhalansi. Ukwenza oku kuqina kuya kuba yinkcitho, i-multi-axis marathon. Ukuyiphosa lukhetho olunengqiqo.
Kodwa nantsi i-rub: ezo zivane zibhityileyo kufuneka zizaliswe ngentsimbi etyhidiweyo ngaphandle kokugodola ngaphambi kwexesha, nto leyo idala izivalo ezibandayo (isiphako esifana nomthungo). Kwakhona kufuneka babe namandla aneleyo okumelana namandla e-centrifugal kunye nokhukuliseko lwe-cavitation enkonzweni. Apha kulapho uyilo lwepateni, inzululwazi yokungena, kunye nokukhethwa kwealloyi kuhlangana khona. Unokukhetha i-17-4 PH engenasici ngokunokwaleka kunye nemvula elandelayo eqina, ikunika umlinganiselo ofunekayo wokomelela ukuya kubunzima.
Senze iprototype yecandelo elifanayo kanye. Okokuqala, iivanes zazigoqeke imizuzu. Ayibonakali emehlweni, kodwa iboniswe ngokuhlolwa kwedayi. Ingxaki yayiyisantya sentsimbi. Siyisombulule ngokulungelelanisa ukuphakama kwekomityi yokuthululela ukunyusa intloko yoxinzelelo, ukunyanzelisa i-laminar engaphezulu. Yayilutshintsho oluchuliweyo olunesiphumo esimangalisayo. Oku akukho kuyo nayiphi na incwadi; luhlobo lwenkqubo intuition eyakhiwe kumakhulu okuthululwa okufanayo.
Umlinganiselo wokwenyani: Ukungaguquguquki phantsi koxinzelelo
Ekugqibeleni, wonke umntu unokwenza umboniso olungileyo. Uphawu lwesiseko esifana nesi sichaziweyo lwenza iwaka elinye lifane nelokuqala. Oku kumalunga nolawulo lwenkqubo, hayi ubugcisa. Imalunga nezenzo zokunyibilika ezibhaliweyo, amaxesha okomisa iqokobhe, iinkuni zokugalela, kunye nokuhlolwa okungqongqo - inqaku lokuqala, elingaphakathi, kunye nelokugqibela.
Umsebenzi wabo weminyaka engama-30 ucebisa ukuba bakhe iinkqubo zoku. Kuthetha ukuba banokusingatha ukuveliswa kwemveliso yoluhlu lwevalvu okanye umgca wezixhobo zesixhobo sotyando, hayi nje enye. I iqokobhe ngundo ukuphosa ubuchwephesha abakhankanyayo buxhasa i utyalo mali; ngamanye amaxesha kancinci kancinci kancinci kodwa indawo enkulu ifaneleka ngcono inkqubo yeresin-iqokobhe. Ukwazi ukuba yeyiphi inkqubo yokucebisa yinxalenye ye-consultancy i-Foundry elungileyo ibonelela.
Ngoko xa ndicinga ilahleko yokuphosa intsimbi, Ndicinga ukuba ngaphantsi kwe-wax kunye ne-chaos elawulwayo yokuthulula, i-metallurgical discipline, kunye ne-handoff engenamthungo yokugqiba. Litsheyini. Ukomelela kwenxalenye yokugqibela kulungile kuphela njengelona khonkco libuthathaka kwelo khonkco. Imveliso yokwenyani ayikho nje imilo yentsimbi; lulwazi oluzinzisiweyo olwaqinisekisa ukuba yenziwe kakuhle.
