Uma abantu bekhuluma 'ngezinhlobo zemishini enembayo', bavame ukufaka ohlwini izinqubo ezifana nokugaya, ukujika, ukugaya. Lokho akulona iphutha, kodwa kugeja iphuzu. Indaba yangempela imayelana nokukhetha inqubo efanele yezinto ezisezandleni zakho kanye nokubekezelelana emdwebeni, nokuthi lezo zinqubo ngokuvamile kufanele zisebenze kanjani ndawonye. Ngibone amadizayini amaningi kakhulu acacisa ukuqedwa okungaphezulu okungafinyeleleka kuphela ngokugaya, kodwa ingxenye yejiyomethri yenza ukubamba ukugaya kucishe kungenzeki. Kulapho 'izinhlobo' zangempela ziqala khona ukudlala—hhayi nje imishini, kodwa ukulandelana nenjongo.
Iqala Ngokulingisa: Isisekelo Somachining
Lokhu kungase kubonakale kusobala, kodwa awukwazi ukukhuluma ngokunemba kwemishini kumongo wethu ngaphandle kokuqala ngokusakaza. Ukulingwa okubi kuqinisekisa ingxenye eyenziwe ngomshini egcwele ubuhlungu bekhanda. Ngisebenze nabahlinzeki abaphatha ukulingisa nokwenza imishini njengemihlaba ehlukene, futhi umphumela uhlala uba yizindleko nesikhathi esengeziwe. Inkampani eyenza lokhu ngendlela efanele, njengokuthi I-Qingdao Qiangsenyuan Technology Co., Ltd. (QSY), isebenza ngendlela ehlukile. Ngaphezu kweminyaka engama-30 kukho kokubili ukulingisa nokwenza, bayaqonda ukuthi isikhunta esihle segobolondo noma ukufakwa kwe-investimenti akukhona nje ukuma; imayelana nokunikeza isisekelo esingaguquki, somsindo esinokucindezeleka okuncane okuyinsalela. Ukukhanda ingxenye kusuka ekufakweni kwe-alloy esekelwe ku-cobalt kuyisipiliyoni esihlukile kunokuqala ngesitoko sebha esenziwe—amapharamitha womshini, ukuguga kwamathuluzi, yonke into iyashintsha.
Indlela yabo ngezinto ezifana ne-ductile iron noma 316 insimbi engagqwali iwukucabangela umshini kusukela esigabeni sephethini. Ama-engeli asalungiswa, imigqa yokuhlukanisa, wonke abekwe ngeso likamashini. Lokhu akulona ithiyori; imayelana nokugwema isimo lapho uzama ukusika khona odongeni oluncane oluyinsimbi, okubangela ukudlidliza futhi konakalise isiphetho. Ngikhumbula iphrojekthi yezindlu zamaphampu lapho idizayini yokuqala yokulingisa yayinendawo yokuvala ebucayi endaweni eyayicishe ingenakuqhathaniswa. Kwakungenxa yokuthi i-Foundry (enye enomshini ohlanganisiwe njengoba ungase uthole kuyo tsngtaocnc.com) ibandakanyeke kusenesikhathi ukuthi siklame kabusha umongo ukuze sivumele ukufinyelela kwamathuluzi okufanele.
I-synergy ibalulekile. Ubuchwepheshe babo kukho kokubili ukubunjwa kwe-shell mold kanye ne-CNC machining ngaphansi kophahla olulodwa kusho ukuthi ukuhlelwa kwenqubo kuhlanganisiwe. Ukulingisa akukhona nje ukungenalutho; yisinyathelo sokuqala, esibalulekile ekulandelaneni komshini wokunemba. Lokhu kususa ukuqagela okuningi kanye nokushintshwa kokusola okwenzekayo lapho kuthengwa abathengisi abahlukene.
CNC Machining: The Workhorse kanye Nuances Its
Manje, ngena emcimbini omkhulu. Uma sithi CNC machining, isonto elibanzi. Ngevolumu ephezulu, izingxenye ezilula kakhulu kusuka ekulingiseni kwazo, izikhungo zokugaya ezinama-axis amaningi ziyindlela yokuya. Kodwa igama elithi 'ukunemba' lapha lihlobene. Ukubamba u-±0.05mm kubakaki bensimbi kuyinto eyodwa; ukuzuza ±0.005mm esihlalweni sevalvu sengxubevange ekhethekile kungesinye isilo ngokuphelele.
Ukukhetha phakathi kwe-3-eksisi, 4-eksisi, noma 5-eksisi akukhona nje ubunzima; ngokuvamile kumayelana nokunciphisa ukusetha. Ngaso sonke isikhathi uma ulungisa kabusha ingxenye, wethula iphutha elingaba khona. Ngengxenye eyinkimbinkimbi ye-investment-cast turbine ku-nickel-based alloy, singahlala sikhetha umshini we-5-axis ukuze uqedele izindawo ezibucayi ekusetheni okukodwa. Izindleko ngehora ziphezulu, kodwa ingxenye yokugcina yokunemba nokungaguquguquki kungcono kakhulu. Ngenze iphutha lokuzama ukonga imali ngokuhlukanisa imisebenzi phakathi kwemishini yama-axis angu-3, futhi ukunqwabelana kokubekezelela ukunqwabelana bekuyiphupho elibi ukulungisa.
Bese kuba khona ukuphenduka. Ezingxenyeni ezijikelezayo ezivela esitokisini sazo sensimbi noma insimbi, ukujika kwe-CNC ngamathuluzi abukhoma kubalulekile. Kodwa ukunemba ukuvula insimbi engagqwali, ikakhulukazi amamaki aqinile, umdanso phakathi kwejubane, okuphakelayo, nokupholisa. Inhlanganisela engalungile iholela ekusebenzeni ukuqina, okube sekucekela phansi ithuluzi lakho futhi konakalise ubuqotho obungaphezulu. Kuwulwazi oluthinta inhliziyo—ukulalela ukusikwa, ukubuka umbala we-chip nokuma kwayo. Ayikho imanuwali yokuhlela engakufundisa lokho ngokugcwele.
Okuthinta Ukuqeda: Lapho Ukunemba Kweqiniso Kuvela Khona
Lapha yilapho izingxoxo eziningi ezinhlotsheni zomshini wokunemba zingafinyeleli khona. Baphatha ukugaya/ukuguqula njengokuphela. Eqinisweni, ezingxenyeni ezidinga ukunemba kwangempela—cabanga ngama-hydraulic manifolds, izihlalo ezinezihlalo, noma izindawo zokuvala—leso yisigaba sokuqeda kancane. Ukugaya kulapho kwenzeka khona umlingo. Kodwa ngisho nokugaya kunezinhlobo zakho: ukugaya phezulu, ukugaya i-cylindrical, ukugaya okungenasici.
Sasinomsebenzi wokwenza umphini wensimbi eqinile. Ukuphenduka kwasondela, kodwa ukulingana okuthwalayo kudinga ukuqedwa kwe-Ra 0.2μm kanye nokubekezelela kwejometri kwama-microns ambalwa. Leyo yindawo yokugaya eyicylindrical. Iqhinga kwakuwukulandelana: ukuphenduka okungekuhle, ukuphathwa kokushisa, ukuphenduka kokuqeda, bese ugaya. Uma uzama ukugaya izinto eziningi kakhulu ngemva kokuphathwa ukushisa, ukhiqiza ukushisa okukhulu futhi ubeka engcupheni ukushisa okungaphezulu. Kuyisenzo sokulinganisa.
Ngezinye izikhathi, ngisho nokugaya akwanele. Ezindaweni ezibushelelezi kakhulu noma ukususa iziqongo ezincanyana kakhulu ezishiywa ukugaywa, ukucijwa noma ukugqwala kuyangena. Lokhu akuvamile ezitolo zemisebenzi evamile kodwa kusemqoka ezimbonini ezifana namandla oketshezi noma i-aerospace. Ngikhumbula i-valve spool esayenza eyayilokhu inamathela ngemva kokugaya. Inkinga bekuwukuzamazama okuncane, okungaphansi kwe-micron endaweni eyisilinda. Isixazululo kwaba inqubo yokucija ngokushesha. Ayizange ishintshe ubukhulu, kodwa iguqule ukuthungwa kwendawo ngokwanele ukuze isebenze kahle. Lona umehluko: ukunemba akuyona nje inombolo; kuyisici esifanele sohlelo lokusebenza.
Izinto ezibonakalayo nguMashiqela
Awukwazi ukuhlukanisa uhlobo lomshini kusukela kokubalulekile. Ukusebenza nge QSYIzinto ezijwayelekile ezifana nensimbi yokusansimbi ziyathethelela; isebenza kahle, ikhiqiza ama-chips amafushane, futhi inomusa kumathuluzi. Insimbi iqinile kodwa iyabikezelwa. Insimbi engagqwali, ikakhulukazi amamaki e-austenitic, i-gummy futhi ijwayele ukuya onqenqemeni olwakhiwe. Udinga amathuluzi abukhali, ama-engeli e-rake aqondile, futhi mhlawumbe ne-coating ehlukile.
Kodwa inselele yangempela ukukhethekile kwabo: ama-alloys asekelwe ku-cobalt kanye ne-nickel. Lezi yizinto zamaphupho amabi kuchwepheshe bemishini abangazilungiselele. Zisebenza-zikhuni ngokushesha, ziyaluma kakhulu, futhi ukuguquguquka kwazo okushisayo kubi, ngakho-ke ukushisa kugxila onqenqemeni lokusika. Kulokhu, konke kuyashintsha. Isivinini siphansi, okuphakelayo kungase kube phezulu ukuze ungene ngaphansi kongqimba oluqinile lomsebenzi, futhi ukukhetha ibanga le-carbide kubalulekile. Sifunde kabuhlungu ukuthi ukusebenzisa isigayo esijwayelekile esihlanganiswe ne-TiAlN engxenyeni ye-Stellite kuvele kubangele ithuluzi elincibilikisiwe kanye nokusakaza okulahliwe. Ukushintshela ebangeni elikhethekile elinokuqukethwe okuphezulu kwe-cobalt kanye nejometri ehlukile kwakuyindlela kuphela. Yilapho isipiliyoni somphakeli, njengeminyaka engama-30 ephawulwe I-Qingdao Qiangsenyuan Technology Co., Ltd., iba yinto ebambekayo—cishe basebenzise amathuluzi anele ukwazi ukuthi yini esebenzayo.
Isu lokupholisa liba semqoka lapha. I-high-pressure, ngokusebenzisa-ithuluzi ukupholisa akuyona into ewubukhazikhazi; kuyisidingo sokuhlephula ama-chips futhi ususe ukushisa. Kwesinye isikhathi, ukuze siqedele amaphasi alawa ma-superalloys, singasebenzisa indlela encane yokuthambisa i-quantity lubrication (MQL) ukuze sifinyelele isiphetho esingcono ngaphandle kokushaqeka okushisayo. Akukho usayizi owodwa olingana-konke.
Ukuhlanganisa Konke: Ukulandelana Kwezwe Langempela
Ngakho-ke, ibukeka kanjani inqubo yokwenziwa ngokunemba kwengxenye eyinkimbinkimbi? Ake sithathe i-impeller ecatshangelwayo kodwa yangempela yepompo yensimbi engagqwali e-duplex, evela ekubunjweni kokutshalwa kwezimali. Okokuqala, ukubunjwa okuvela ku-Foundry kufanele kuhlolwe. Mhlawumbe ukudubula okusheshayo ukuqhumisa ukukuhlanza. Bese, iya ku-lathe ye-CNC yokuphendula i-bore nobuso bangemuva—lokhu kuveza i-datum eyinhloko. Okulandelayo, ithuthelwa kumshini we-4 noma 5-eksisi. Lapha, ama-blades, i-shroud yangaphambili, nanoma yiziphi izikebhe zenziwa ngomshini. Lokhu kusikwa okusindayo, okuphazamisekile, ngakho ukuzinza kwethuluzi kubalulekile.
Ngemuva kwalokho, mhlawumbe kunesinyathelo sokunciphisa ingcindezi uma umshini ube nolaka. Bese, buyela ku-lathe noma kumshini wokugaya ukuze uqedele izindawo ezibucayi zokuvala futhi ubhoboze ekubekezeleleni kokugcina. Okokugcina, ukukhipha, ukuhlanza, futhi mhlawumbe inqubo yokunciphisa insimbi engagqwali. Kuyo yonke le nto, ukuhlolwa kunqanyuliwe-ngemva kwe-op yokuqala, ngemuva kokuqina, ngemuva kokuqeda. Awukwazi ukuhlola ikhwalithi ube yingxenye ekugcineni.
Iphuzu liwukuthi, 'izinhlobo' zokunemba kwemishini yilezi zigaba, ngasinye sikhethwe ngesizathu. Ukugeleza. Isitolo esenza ukugaya kuphela singase sikhiqize ingxenye, kodwa isitolo esiqonda lonke iketango, kusukela endleleni yokusakaza kuya ekucijeni kokugcina, njengokusebenza okuhlanganisiwe, sikhiqiza ingxenye ethembekile. Ukwehluleka engikubonile kuvame ukuvela ekunqanyulweni kwalolu chungechunge—i-maachingist iphusha ukudla phezulu kakhulu ukuze yonge isikhathi, yonakalise indawo engaphansi yesinyathelo esilandelayo sokugaya, noma inqubo yokuphatha ukushisa engazange ibalwe kwizibonelelo zomshini.
Ekugcineni, ukuhlukanisa ngohlobo lomshini kuyisiqalo. Kodwa ubuchwepheshe beqiniso busekuqondeni ukuthi lezi zinqubo zisebenzisana kanjani, ukuthi izinto ezisetshenziswayo ziyilawula kanjani imithetho yazo, nokuthi isisekelo—ukubunjwa okwenziwe kahle—kwenza konke ukunemba okulandelayo kungenzeki nje kuphela, kodwa kusebenze ngokwezomnotho. Lowo ngumbono owutholayo ngokuba sesitolo, hhayi nje ngokufunda ikhathalogi.
