Lapho onjiniyela becacisa ukufakwa kwensimbi empunga yamavalvu asebenza ngamandla kahydraulic asebenza ngamandla kakhulu noma amaphampu ezindlu, abagcini nje ngokukhetha into ethile—babheja ukuzinza kwe-dimensional ngaphansi kwamabhayisikili ashisayo, ukumanzisa okungaguquguquki ezinhlelweni ezidlidlizayo, kanye nokuziphatha okuxegayo okungabikezelwa ngemva kwamahora okusebenza angu-10,000+. Kungakho ukusesha a Imboni yenkampani yokuphonsa insimbi empunga akuvamile ukuthi kuqale ngentengo—futhi cishe njalo kuphetha ngokulawulwa kwenqubo, ukulandeleka kwe-metallurgical, kanye nokungabekezeleli ukuncipha okuncane emigwaqweni ebucayi yomthwalo.
QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD. isebenzisa isikhungo esisodwa esinjalo e-Qingdao—hhayi njengesizinda esijwayelekile, kodwa njengozakwethu wengxenye yokunemba okuhlanganisiwe lapho yonke insimbi empunga ihlolwa ithola ukuqinisekiswa okugcwele kwekhemikhali yezinga le-batch ngokumelene ne-ASTM A48 Class 30B kanye nezicaciso ze-EN-GJL-250. Sibone amakhasimende ebuyela eku-odeni kabusha izindlu zesilinda sephampu ye-piston ngemva kweminyaka emithathu—hhayi ngoba izingxenye zehlulekile, kodwa ngenxa yokuthi iqoqo labo lasekuqaleni lika-2021 lisahlangabezane nokubiza kwe-GD&T ngaphakathi kuka-±0.015 mm kuzo zonke izici ze-datum eziyi-12. Lokho kuvumelana akwenzeki ngephutha. Ibhakwa ibe yimithethonqubo yokushaja esithandweni somlilo, izingodo zokucindezela kwesikhunta, kanye nemijikelezo yokukhulula ukucindezeleka kwangemva kokuphonswa kukalwa ngokwengxenye yesisindo nobukhulu besigaba.
Yini ehlukanisa lokhu Imboni yenkampani yokuphonsa insimbi empunga kusuka kubahlinzeki abagxile kwivolumu? Amaqiniso amathathu okusebenza:
- Ukuthola izinto ezibonakalayo akuxoxiswana ngakho: Wonke amaqoqo ensimbi empunga aqala ngensimbi yengulube eqinisekisiwe evela kuzincibilikisi ze-ISO 9001—akukho ukuxutshwa kwezihlakala ngaphandle kokuhlaziywa kwe-spectral. Ukushisa ngakunye kuphethe umbiko wokuhlolwa komshini (i-MTR) oboshwe enombolweni yenkatho yakhona, futhi amabha aqinile ayadonswa futhi ahlolwe ngaphambi kokuthi kuqale noma yimuphi umshini.
- Ukusakaza akuhlukanisiwe - kuklanywe ngokubambisana nomshini: Isikhunta sesihlabathi sihlanganisa izibonelelo ze-machinability ezisekelwe emigwaqweni yokugcina yamathuluzi ye-CNC. Isibonelo, i-winch center shaft roller ithola ama-engeli asalungiswa endawo kuphela lapho amathuluzi okugaya afinyelela khona; kwezinye izindawo, izindawo ezingaphezulu zihlala zinjengokuphonswa ukuze kulondolozwe ubuqotho be-graphite flake kanye nomthamo wokudambisa. Lokhu kucabanga okuxubile kunciphisa isikhathi sokuhola ngo-22% ngokwesilinganiso uma kuqhathaniswa nokucaphuna okulandelanayo.
- Ukuhlola akukona ukugcinwa kwesango—kuyimpendulo: Konke ukulingisa kudlula esiteshini se-Zeiss CONTURA CMM ngaphambi komshini onzima. Ukuchezuka akurekhodwa nje—kubangela ukubuyekezwa kwembangela nonjiniyela be-Foundry. Inkinga yekhasimende eyodwa ephindelelayo yokungaqondi kahle ilandelelwa emuva ekuphambukeni okuyinhloko kokuphrinta ngesikhathi sokunyakaziswa. Ukulungisa? Ukulandelana okubuyekeziwe okuyisisekelo kwebhokisi—hhayi ukuguqulwa kwedizayini.
Abanye bangase baphikise ngokuthi i-iron empunga “iyinto yefa”—esithwe yi-ductile iron noma insimbi eyimpushana ekusetshenzisweni kokucindezeleka okukhulu. Kodwa ekusetshenzisweni komhlaba wangempela, iphethe izinzuzo ezihlukile: ukudlidliza okuphakeme ezisekelweni zephampu, izindleko eziphansi nge-cubic-intshi ngayinye yezindlu zengxenye enkulu, kanye nokuqina okuqinisekisiwe kokumelana nemizimba yamavalve kawoyela negesi echayeke ekugibeleni amabhayisikili okusheshayo okungu-50°C–200°C. Lapho i-ductile iron iqhekeka ngaphansi kokushaqeka okushisayo okuphindaphindiwe, i-ayoni empunga ivamise ukumila ama-microcracks azinzile, azibekela yona avimba ukusakazeka okuqhubekayo. Siqinisekise lokhu emizimbeni yamavalvu omfutho atholwe enkambweni evela ezisekelweni zoLwandle lwaseNyakatho—zisasebenza ngemva kweminyaka engu-17, ngaphandle kokumbozwa kwendawo.
Lesi sikhungo sisekela izindlela zokuphonsa ezimile nezimaphakathi, kodwa ezintweni ezifuna ukulawulwa ukujiya kodonga—njengezingxenye zephampu yengxube ye-cobalt ye-AMS 5387 efakwe ngqo kumanifold ensimbi empunga—ukugxila kuhlala ekubunjweni kwesihlabathi nokubunjwa okuhlanganiswe ne-resin. Kungani? Ngoba iletha inkululeko yejiyomethri edingekayo eziteshini zokupholisa zangaphakathi, abaphathi abakhuphukayo, nemisele ehlanganisiwe yophawu—konke ngokuthela okukodwa. Awekho ama-welds ahlanganisiwe. Azikho izindlela ezivuzayo. Azikho izinqubo zokujoyina zesibili ezibeka engcupheni ukuqhubeka kwesakhiwo.
Okwamaqembu okuthenga ahlola a Imboni yenkampani yokuphonsa insimbi empunga, buza le mibuzo ngaphambi kokusayina i-NDA:
- Ungakwazi yini ukunikeza ama-MTR nedatha yokuqina kokushisisa okuthathu kokugcina okusetshenziswe engxenyeni yethu yenombolo?
- Uqinisekisa kanjani i-graphite morphology—futhi uyini umkhawulo wakho wokwenqatshwa kohlobo D (owonakele) ezindaweni ezibucayi?
- Ingabe imibiko yakho yokuhlola ihlanganisa idatha ye-CMM point-cloud—hhayi nje ukudlula/ukufeyila izifinyezo?
- Yikuphi ukuhluka kwakho okuphezulu okuvumelekile ekutheleni izinga lokushisa kusethi eyodwa yesikhunta?
I-QINGDAO QIANGSENYUAN TECHNOLOGY iphendula ngoyebo kuzo zozine—ngobufakazi obubhaliwe. Ukugeleza komsebenzi wabo okuthobela i-ISO akugcini ekusakazeni. Kunwetshwa ngokuqinisekiswa kokwelashwa kokushisa (lapho kucacisiwe), i-CNC ye-multi-axis iqeda ngokuhlola okungaphakathi kwenqubo, nokuhlola okusebenzayo okufana nokuhlola ingcindezi ye-hydrostatic ku-1.5× ingcindezi yokusebenza. Konke okuthunyelwayo kuhlanganisa idosi yokulandeleka: ilogi encibilikayo, umbiko we-X-ray (uma kudingeka), inguqulo yohlelo lomshini, nesitifiketi sokugcina sokuhlola esisayinwe ukuhola kwe-QA.
Lokhu akukona mayelana nokukala okukhiphayo—kumayelana nokukala ukwethembeka. Njengoba isikhathi sokuphila kwemishini yezimboni sidlula iminyaka engama-25 futhi ukuphelelwa yisikhathi kwengxenye esikhundleni kuba yingozi yezinga eliphezulu, inani le- Imboni yenkampani yokuphonsa insimbi empunga ephatha ukulingisa ngakunye njengempahla ye-serialized—hhayi impahla—iyakhuphuka kuphela. Isizukulwane esilandelayo sezinhlelo ze-hydraulic ngeke zidinge amandla engeziwe. Bazodinga ukubikezelwa okwengeziwe. Futhi lokho kuqala isikhathi eside ngaphambi kokuba i-ladle yokuqala ithulule.
