Wake wazama ukuthela insimbi encibilikisiwe esikhunjeni se-wax—ukuze nje uyibuke iqhekeka, ijika, noma icuphe amabhamuza omoya acekela phansi ingxenye yokugcina? Sikubonile kwenzeka kwabathathu kwabane okokuqala ishabhu yokuphonsa i-wax elahlekile amaseshini. Hhayi ngoba le nqubo inephutha—kodwa ngenxa yokuthi ukunemba kudinga okungaphezu kokushisa nokubekezela. Idinga ukwethembeka kwephethini, ukutubeka okulawulwayo, ubuqotho begobolondo elithile le-alloy, kanye nempendulo yesikhathi sangempela esishisayo phakathi nokuthela. Kungakho ochwepheshe abavela kuma-hydraulic valve OEMs eJalimane ukuze bampompe abaklami eTexas manje bengaphathi ukutshala imali njengesevisi yebhokisi elimnyama—kodwa njengesiyalo sobunjiniyela esihlanganyelwe.
Kwa-QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD., sisebenza ngokubambisana ishabhu yokuphonsa i-wax elahlekile izikhathi—hhayi ezabokuzilibazisa, kodwa okonjiniyela abacacisa imibhobho ye-cobalt alloy AMS 5387 noma izindlu zephampu ezisekelwe ku-T800. Lezi akuzona izinsuku zedemo. Abahlanganyeli baletha imidwebo yabo ye-GD&T. Siyawavivinya ekubunjweni kwamagobolondo wangempela akhiwe kusuka kumafayela awo e-STL. Sikala ukuncipha ngokuqhathaniswa namanani abikezelwe—futhi silungisa amasistimu okungena bukhoma. Iklayenti elilodwa lithole ukuchezuka kokuqina kodonga okungu-0.12 mm endaweni yalo yesilinda sephampu ye-piston kuphela ngemva kokubona izingxenye eziphambanayo ngaphansi kwe-optical metrology. Lokho kuqonda kusindise amasonto ayisithupha okusebenza kabusha.
Kungani leli zinga lokuqina libalulekile? Ngoba ukukhishwa kwe-wax elahlekile kwehluleka buthule. Iphutha lokuqukethwe kwe-silica elingu-2% kungqimba lwe-stucco ngeke limise ukukhiqizwa—lizovele lishintshe ukusatshalaliswa komngcele wokusanhlamvu ezindaweni ezinomfutho ophezulu. Ukuchezuka okungu-5°C ngesikhathi sokuxosha kungashiya izinsalela ezincane ezikhipha i-oxidize ngesikhathi sokuthela, okubangele ukugoba kwe-pinhole ku-1,450°C. Singene ngaphezu kokuthululwa okungu-1,200 ku-cobalt-nickel, insimbi engagqwali, ne-ductile iron—futhi konke ukwehluleka kulandelela emuva kweyodwa yezimbangela ezine: izinga lokunwetshwa kwe-wax elingaguquki, i-slurry viscosity engaqinisekisiwe, imijikelezo yokumisa igobolondo engafani, noma izinga lokushisa elingafanele lensimbi/i-slag. Ishabhu yethu ihlukanisa inguquko ngayinye. Awuyibuki ividiyo. Ulinganisa i-viscometer. Wena amagobolondo womisa isikhathi ngaphansi komswakama olawulwayo. Uqhathanisa imiphumela ye-XRF kusukela kumaqeqebana amabili we-AMS 5387—ihlangothi nehlangothi.
- Ukuqinisekiswa kwephethini ye-wax: Sisebenzisa ama-micrometer edijithali kanye ne-CT scan ukuze siqinisekise ukukhukhuleka kobukhulu ngaphambi kokwakhiwa kwegobolondo—hhayi ngemva
- Iphrofayili yokushiswa: Izilinganiso zohlelo lwabahlanganyeli berempu ezithandweni zethu ezilungisekayo, bese uhlola izinsalela ngesithombe se-SEM
- Ukuhlolwa kwamandla egobolondo: Ukuhlola okuguquguqukayo kwe-ASTM C1161—okwenziwa kumasampula adonswe phakathi nenqubo
- Thela ukulingiswa: Amalungu afanayo esikhathi sangempela se-thermocouple alandelela isivinini sangaphambili kumasistimu okugenca wangempela
- I-post-cast metrology: Izikena ze-CMM ezimbozwe ku-CAD yoqobo—igqamisa amavektha ahlanekezela ashisayo
Abanye bangase baphikise ngokuthi imishini ye-CNC iqeda isidingo sobuchwepheshe bokusakaza. Kodwa zama ukugaya umphimbo we-cobalt alloy owugqinsi ongu-3.2 mm ngamashaneli okupholisa angaphakathi—futhi uzofinyelela imikhawulo yokuphila kwamathuluzi emizuzwini embalwa. Ukufakwa kwe-investimenti kuletha i-geometry yomumo wenetha lapho imishini ingakwazi ukufinyelela khona. Ukubanjwa? Kufanele ulawule i-microstructure *ngaphambi kokuba* insimbi iqine. Yingakho iworkshop yethu ihlanganisa isikhathi selebhu ye-metallurgical: ababambiqhaza bahlaziya isikhala sezingalo se-dendrite kumakhuphoni abo athululiwe, basihlobanise nezingodo zesilinganiso sokupholisa, futhi balungise idizayini yesikhuphukeli ngokufanele. Ayikho ithiyori. Isanda kukalwa i-delta-T ngokumelene namashadi kasayizi wokusanhlamvu aphrintiwe kusayithi.
Asifundisi “ukusakaza”. Sifundisa ukuthi *ungakuqinisekisa* kanjani lokho okusakazayo. Wonke umhlanganyeli uhamba neshidi lenqubo elibhaliwe—eligunyazwe ngokumelene ne-ISO 8062 ukubekezelelana kwejometri kanye namazinga okulinganisa okufakwa kwe-ASTM E1245. Uzokwazi kahle ukuthi isiphi isilinganiso se-slurry binder esibambelela ngaphansi kwe-1,500 psi hydrostatic pressure. Imuphi usayizi we-stucco grit ovimbela ukufakwa kwesihlabathi ezingxenyeni zodonga ezingu-0.8 mm. Yikuphi ukushisa kokushisa okushisa okuqeda ukuqhekeka kokushaqeka okushisayo ku-T800 alloy housings. Lokhu akukhona ukuqeqeshwa. Ubunikazi benqubo obudlulisekayo.
Uma ucacisa amavalvu okucindezela kawoyela ongasogwini—noma ukuklama ama-winch center shaft roller ezimoto zezimayini—udinga okungaphezu komhlinzeki. Udinga uzakwethu ophatha umdwebo wakho njengedokhumenti ephilayo—hhayi i-PDF emile. QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD. iqhuba lezi zifundo isuka endaweni yayo ethobela i-ISO ye-Qingdao, lapho ukulingisa, ukuqedwa kwe-CNC, kanye ne-metrology kusebenza ngaphansi kophahla olulodwa. Awekho ama-handoffs. Akukho ukulahleka kokuhumusha phakathi kwe-Foundry nesitolo somshini. Izitifiketi zezinto ezibonakalayo ezilandelekayo, amarekhodi eqoqo aphelele, nedatha enobukhulu evunyelaniswe kusistimu yakho ye-PLM. Okulandelayo ishabhu yokuphonsa i-wax elahlekile iqala ngoMeyi. Letha ingxenye yakho enzima kakhulu. Sizokukhombisa ukuthi inqubo iqala kuphi—futhi lapho abanye abaningi bema khona maduze.
