Uma abantu abaningi bezwa 'indawo yokutshala imali,' babona indawo yokusebenzela enothuli egcwele amaphethini we-wax kanye nodaka lwe-ceramic. Lokho kuyingxenye yakho, impela, kodwa kufana nokuchaza imoto ngomsebenzi wayo wokupenda. Indaba yangempela isesilawulweni sokubekezelelana, idizayini yesistimu yokugenca engabonwa muntu, kanye nokuvumelana kwensimbi ukusuka ekushiseni kuye ekushiseni. Amakhasimende amaningi afika ecabanga ukuthi konke kumayelana nokuzuza 'isimo senetha.' Ngingaphikisa ukuthi kuningi mayelana nokuzuza umumo obikezelwayo, othembekile, iqoqo ngemva kwenqwaba, lapho izindleko zangempela zingekho enanini leyunithi kodwa esilinganisweni se-scrap kanye nesikhathi somshini esisezansi nomfula oyongayo—noma ungasilondolozi.
I-Shell Game: Akuyona Nje Ukumboza
Inqubo yokwakha igobolondo yilapho isisekelo sibekwe khona, ngokwezwi nezwi. Ivamise ukubukelwa phansi. Asigcini nje ngokucwilisa isihlahla se-wax endaweni ewudaka ne-stucco. I-viscosity yejazi eliyisisekelo, okuqukethwe kukafulawa we-zircon, umswakama wendawo yokomisa kanye nezinga lokushisa—okuguquguqukayo ngakunye kushintsha indawo yokugcina nokuqina kohlangothi. Ngike ngabona amaqoqo lapho igobolondo lalibonakala liphelele khona kodwa labe selikhombisa imifantu emihle ngemva kokukhipha i-waxing. Umlandu? Umjikelezo wokumisa osheshayo phakathi kwamajazi. Igobolondo lidinga ukuphefumula nokwelapha, hhayi nje ukomisa. Ukuyisheshisa konga usuku kodwa kubiza isonto ngokusebenza kabusha.
Lapha kulapho amashumi eminyaka okusebenza, njengalapho I-Qingdao Qiangsenyuan Technology Co., Ltd. (QSY), humushela emuzweni wemvelo. Uthuthukisa umuzwa ngakho. Uyazi ukuthi isizini ye-monsoon yasehlobo e-Qingdao izowathinta kanjani amathangi ane-slurry futhi ulungise ukwakheka ngaphambi kokulungiselela. Akukho kunoma iyiphi imanuwali; isemabhukwini e-log kanye nenkumbulo ehlangene yabaphathi baphansi. Ukugxila kwabo isikhathi eside ukubunjwa kwegobolondo futhi ukutshala imali kusho ukuthi bakhe umtapo wolwazi wamapharamitha wamajiyometri nama-alloys ahlukene.
Isibonelo, ngezingxenye ezinodonga oluncane lwensimbi engagqwali, igobolondo lidinga ukungeneka okuphezulu ukuze livumele amagesi ukuba aphume ngesikhathi sokuthela, kodwa futhi namandla anele okumelana nokucindezela kwensimbi okumile. Ibhalansi. Ukuyenza ingalungile kusho ukugijima kabi noma ukuphuka kwegobolondo. Sake saba nephrojekthi ye-prototype ye-turbine blade lapho unqenqema olulandela lwalucijile kakhulu. Ukwakhiwa kwegobolondo elijwayelekile alikwazanga ukumelana nokushaqeka kwe-thermal. Kwadingeka silungise isistimu yokuhlanganisa emajazini ayinhloko, sengeze i-refractory ehlukile ukuze sithuthukise amandla aluhlaza kanye nokumelana nokushaqeka okushisayo. Kuthathe izikhathi ezintathu ukuthola ukusakazwa komsindo.
Izinto Zensimbi: Ngaphezu Kokuncibilika Nje
Ekhuluma ngama-alloys, ukukhetha nokuphatha insimbi kungenye i-oversimplification evamile. 'Uthela insimbi engagqwali, akunjalo?' Yebo, yebo, kodwa 304, 316, 17-4PH, noma i-duplex yangokwezifiso? Ngamunye uziphatha ngendlela ehlukile esikhunjeni. Ama-superalloys—i-nickel-based and ama-alloys asekelwe ku-cobalt Uhlu lwe-QSY—luyisilwane esihluke ngokuphelele. Izici zabo zokuncibilika, uketshezi, nendlela ezihlangana ngayo negobolondo zibalulekile.
Umkhathi wesithando somlilo ubalulekile. Kuma-alloys amaningi asebenza kahle kakhulu, awukwazi ukuvele uncibilike emoyeni ovulekile. Sisebenzisa i-vacuum noma ukuncibilika kwe-atmosphere okulawulwayo ukuze sinqande i-oxidation kanye nokucosha ukungcola. Umehluko ezimpahleni zomshini phakathi kokuncibilika okuvikelwe kahle kanye nokufakwe umoya-mpilo kancane ungaba mkhulu, ikakhulukazi ezingxenyeni ze-aerospace noma izinhlelo zokusebenza zezokwelapha. Iwumshayeli obizayo, kodwa akuxoxiswana ngawo ngomsebenzi othile.
Izinga lokushisa lokuthulula kungenye inkokhelo yokwahlulela. Kushisa kakhulu, futhi uzibeka engcupheni yokuguguleka kobuso bangaphakathi begobolondo, okuholela ekulimaleni kokufakwa. Ipholile kakhulu, futhi insimbi ingase ingagcwali izingxenye ezincane. Nge insimbi, une-graphitization okufanele uyicabangele. Alikho izinga lokushisa lomhlaba wonke 'eliphelele'; ububanzi obunciphisa ngokususelwe engxenyeni yejometri kanye nokushisa okuqondile kwengxubevange oyisebenzisayo ngalolo suku. Ufunda ukufunda ubuso bensimbi ku-ladle.
Ukuxhawula kwe-CNC: Lapho Ukusakaza Kuhlangana Nobunemba
Leli iphuzu elibalulekile abaningi abazimele izikhungo zokutshala izimali miss: handoff to machining. Uma ukusakaza kungaklanyelwe kucatshangwa ngomshini, udlulisa izinkinga ezansi nomfula. Ukuvumelana kwe-Dimensional kubaluleke kakhulu. Isisekelo esihle asigcini nje ngokuletha ukubukwa; iletha ukulingisa okuhlezi ngokuzinzile ku-CNC vise, enesabelo sesitoko esibikezelwayo.
Kungakho imodeli ehlanganisiwe endaweni efana ne-QSY yenza umqondo osebenzayo. Baphatha bobabili ukutshala imali kanye ne CNC imishini. Iluphu yempendulo iqinile. Uma ochwepheshe bemishini behlale belwela ukuthola iphoyinti ledatha ngenxa yokuthi amalugi afakwe ukhonkolo awahambisani, lolo lwazi lubuyela emuva ngqo esitolo samaphethini kanye nonjiniyela bezinqubo. Mhlawumbe imingcele yomjovo we-wax idinga ukulungiswa, noma izindawo zokulungisa esihlahleni se-wax zidinga ukuklanywa kabusha.
Sihlanganise isikhungo semishini ye-5-axis esigcwele sokuqedela izingxenye ze-turbine. Amaqoqwana ambalwa okuqala aveze ukuthi izindawo zethu zokulingisa eziteshini ezithile zangaphakathi eziyinkimbinkimbi bezingezinhle ukuthi uphenyo lungakwazi ukufunda kahle. Kwadingeka sibuyele emuva siyocwengisa ijazi lethu lokuqala eliludaka, sisebenzisa i-refractory yezinga elingcono ukuze sithuthukise isiphetho 'sokusakaza' kulezo zindawo ezithile, ukuze nje sinikeze i-CNC ithuba lokulwa. Yengeze isinyathelo enqubweni yethu, kodwa yehlise isikhathi sokwenza imishini kanye nokwehluleka kophenyo cishe ngama-30%.
Ukwehluleka Njengephoyinti Ledatha
Awufundi okuningi ngohlelo oluhle kakhulu. Imisebenzi ehlulekile yizincwadi zokufunda. Ngikhumbula indlu yephampu enkulu ngensimbi engagqwali eyi-duplex. Idlule yonke i-NDT, ibukeka iyinhle. Kodwa ngesikhathi sokuhlolwa kwe-hydro endaweni yeklayenti, kuvuza nge-flange. Imbangela? I-Micro-shrinkage porosity eduze nendawo eshisayo esingazange siyiphakele ngokwanele. Isofthiwe yethu yokulingisa ibiyihlabe umkhosi njengengcuphe encane, kodwa besingazinaki izici ezithile zokuqinisa ingxubevange. Asiyixazululanganga ngokungeza nje insimbi eyengeziwe (okwenyusa izindleko nesisindo), kodwa ngokuklama kabusha umumo weqoqo le-wax nokusebenzisa i-exothermic padding kugobolondo kuleyo ndawo.
Esinye 'isipiliyoni sokufunda' sakudala ukuhlanekezela. Ukusakazwa okude, okuzacile kungasonteka ngesikhathi sokupholisa uma kungasekelwe kahle esithandweni. Sake saba nochungechunge lwezinsimbi eziqondisayo eziphuma nomnsalo omncane. Isixazululo sasingekho ekutheleni; kwakungendlela esasilayisha ngayo amagobolondo ashisiwe emgodini wokupholisa. Siqale ukusebenzisa amasethi e-ceramic ukuwasekela ngobude bawo phakathi nesigaba sokupholisa esibucayi. Kulula, kodwa yalungisa inkinga.
Lezi akuzona izinkinga zethiyori. Yizindida zansuku zonke i-Foundry enomlando wokusebenza ojulile, njengezithenjwa ze-QSY zeminyaka engu-30, eziqongelela izixazululo. Kuyisizinda solwazi esithinta ngokuqondile ukwethembeka nesikhathi sokuhola.
Isilinganiso Sangempela: Ukuvumelana Ngokuhamba kwesikhathi
Ngakho, yini echaza okwaziyo isisekelo sokutshala imali? Akusona isithando somlilo esihle kunazo zonke noma iphrinta entsha ye-wax ye-3D. Ikhono lokusebenzisa i-Job A-105 namuhla bese uyiqhuba futhi ezinyangeni eziyisithupha kusukela manje ngemiphumela efanayo. Kumayelana nokulawulwa kwenqubo esinda ekushintsheni kwabasebenzi nokuhluka kweqoqo lezinto ezibonakalayo.
Lokhu kudinga amasistimu aqinile: ukulawulwa kwenqubo ye-wax eqinile, izindawo ezigcinwe udaka, amajika okudubula abhaliwe, kanye nezingodo zokuncibilika ezinemininingwane. Kuyisicefe, umsebenzi ocophelelayo. Kodwa yilokho okuvumela i-Foundry ukuthi idlulele ngale kwe-prototyping ekukhiqizeni. Ungakubona lokhu kugxila emandleni aqhubekayo ngendlela inkampani ethanda ngayo QSY iyaziveza—igqamisa ukuba khona kwemboni yesikhathi eside kanye nohlu lwezinto ezibonakalayo olukhuluma ngolwazi oluqoqiwe kunokuba nje uhlu lwamathuluzi.
Ekugcineni, inani lisekuba uzakwethu ongabikezelwa. Unjiniyela oklama ingxenye udinga ukwazi ukuthi amandla aqinile kumdwebo azoba lapho engxenyeni. Umphathi wokuthenga udinga ukwazi intengo futhi ukulethwa kusuka ku-oda lesihlanu kuzofanelana nelokuqala. Lokho kuthembana akwakhiwe hhayi ebhodini, kodwa esitezi sesisekelo, ngezinqubo ezilawulwayo nokufunda ukwahlulela kuyo yonke into kusukela kubukhulu begobolondo kuya esivinini sokuthulula. Yilokho umnyombo wobuciko, kude nomfanekiso olula we-wax nomlilo.
