Ngaba ufuna iiprototypes zetsimbi ezisebenzayo-ezikhawulezayo, ezifikelelekayo, kunye nezithembekileyo-ngaphandle kokuzinikela kwizixhobo ezipheleleyo zemveliso? A iprototype yesanti yokugalela umzi-mveliso iibhulorho ukuba umsantsa. Kodwa ayizizo zonke ii-Foundries ezinikezela ngesantya, ukuchaneka, okanye imfezeko yezinto eziphathekayo kwimitsi ephantsi. Sibone abathengi bechitha iiveki ezi-3 ukuya kwezi-6-kunye namawaka eedola-elinde ukuhanjiswa okufika kunye ne-warpage, porosity, okanye i-GD&T enxaxhileyo abayibamba kuphela emva komatshini. Ulungiso aluhambi ngokukhawuleza. Kukudityaniswa okuqinileyo phakathi koyilo lokuyila, ukwenziwa komngundo, kunye nenkqubo ye-metrology ukusuka kusuku lokuqala.
Kutheni ukuphosa isanti kusaphumelela kwiiPrototypes zetsimbi zakwaQala
Ukuchithwa kwesanti akusiyo iteknoloji yefa-yeyona ndlela iphendulayo, eneendleko eziphantsi ukuya kwiindawo zentsimbi ezikufutshane ne-net-shape phantsi kwe-100 kg. Ngokungafaniyo nokuphosa utyalo-mali, itsiba iipateni ze-wax kunye namaqokobhe e-ceramic. Ngokungafaniyo ne-die casting, iphatha i-cobalt alloys, iintsimbi ezingenasici, kunye neentsimbi eziphezulu ze-silicon ngaphandle kweendleko zokuthintela izixhobo. Ipateni enye enokuphinda isetyenziswe-i-CNC-eyenziwe nge-aluminium okanye i-resin-coated wood-ixhasa i-5 ukuya kwi-20 iprototype yokugalela. Ixesha lokukhokela liyehla ukuya kwiintsuku eziyi-10-18. I-Material flexibility ihlala iphezulu: I-ASTM A48 Iklasi ye-30 yentsimbi engwevu, i-ASTM A197 isinyithi esithambileyo, i-ASTM A27 LCC yensimbi ye-carbon, kunye ne-AMS 5387 cobalt-nickel superalloy-yonke i-castable kunye nokuqiniswa okulawulwayo kunye nokuphathwa kobushushu emva kokugalelwa.
Kodwa isantya asithethi nto ukuba ukuphosa kuyagqwesa ngexesha lokupholisa okanye kusilele ukuqinisekiswa komda kwisikhululo seCMM. Kulapho iivenkile ezininzi ze "prototype" zisilela khona. Baphatha ukugaywa kwesanti njengenkqubo ezimeleyo-kungekhona njengendawo yokuqala kwikhonkco lokuvelisa elichanekileyo. Siye salinganisa ukuya kuthi ga kwi-0.8 mm yokuncipha okungalindelekanga kwi-molds engalawulwayo yesanti eluhlaza kwizindlu ze-cylinder zepompo. Oyena nobangela? Uxinzelelo lwe-ramming olungaguqukiyo, utshintsho lwe-ambient humidity, kwaye akukho xesha lokwenyani lokujongwa kweshifti. Ukulungisa oko kufuna uqeqesho lomgangatho osisiseko-hayi nje ukulinganisa isoftware.
Yintoni eyahlula iPrototype eyiNyaniso yeFactory yokuphosa isanti kwi-General Foundry
Ozinikeleyo iprototype yesanti yokugalela umzi-mveliso isebenza phantsi kwemiqobo emithathu engenakuxoxisana: ukulandeleka, ukuphinda-phinda, kunye nokuphendula. Hayi umthamo. Hayi ixabiso eliphantsi. Nantsi indlela edlala ngayo ekusebenzeni:
- Ukulandeleka kwezinto kuqale ekunyibilikeni: Yonke ibhetshi ithwala iingxelo zovavanyo lwemill eqinisekisiweyo (MTRs), izigodo zesithando somlilo, kunye nohlalutyo lwe-spectral. Akukho zilebhile "ze-alloy yegeneric". Kwizinto ezisekelwe kwi-T800 ye-cobalt, siqinisekisa umxholo we-cobalt ngaphakathi kwe-± 0.3%, i-chromium ngaphakathi kwe-± 0.2%, kunye nekhabhoni ngaphakathi kwe-± 0.02%-kungekhona nje ukuthobela i-AMS 5387, kodwa ukuhambelana kuyo yonke into.
- Ulawulo lwe-Dimensional luqala ngaphambi kokugalela: Sisebenzisa ukuskena kwe-3D kwipatheni nganye kunye nebhokisi engundoqo-kungekhona nje ukugqithiswa kokugqibela. Ukuba umzobo wezindlu wempompo yepiston ubiza ± 0.15 mm kukulungelelaniswa kwebhore, siqinisekisa i-angle yedrafti yepateni, i-offset ye-parting line, kunye nendawo yokushicilela engundoqo *phambi kokuba* isanti ipakishwe.
- Impendulo ivala ngeeyure, hayi iintsuku: Xa umthengi engenisa umzobo we-GD & T-heavy valve body, iqela lethu lobunjineli libuyisela amanqaku e-manufacturability-kuquka iingcebiso ze-gating, ukufakwa kwe-riser, kunye nezibonelelo ezilindelekileyo ze-stock machining-ngaphakathi kweeyure ze-48 zeshishini. Akukho kulinda abacebisi bangaphandle.
Abanye banokuphikisa ukuba ukuphosa isanti akukwazi ukubamba unyamezelo oluqinileyo. Kodwa sihlala sibamba i-± 0.25 mm kwiimpawu ezibalulekileyo ezifana nezangqa ze-flange kunye ne-shaft bores-nakwi-450 mm-long body valve hydraulic valve-usebenzisa isanti elawulwa yi-resin-bonded, i-vacuum-assisted mold compaction, kunye ne-post-shakeout stress relief. Umahluko awungomlingo. Ibhalwe iiparamitha zenkqubo, izixhobo ezilinganisiweyo, kunye neenjineli eziphose i-12,000+ yeendawo zoshishino ukusukela ngo-2015.
Isiphumo sokwenyani sehlabathi: Yintoni oyifumanayo ngokwenene
Xa usenza iprototype yokwenyani yomzi-mveliso wokugalela isanti, awufumani ukuphoswa ekrwada kunye nebhilikhwe yokulayishwa. Ufumana inxalenye eqinisekisiweyo, elungele umatshini-kunye namaxwebhu apheleleyo. Yonke impahla ethunyelwayo ibandakanya:
- Ingxelo esayiniweyo enomlinganiselo ebonisa amaxabiso anomlinganiselo weCMM ngokuchasene nomzobo wakho, enekhowudi yokupasa enemibala/yenqanaba lokusilela kwindawo nganye
- Iifoto zendawo yokuphosa-ebonisa nayiphi na i-porosity encinci okanye ukukhanya okuwela ngaphakathi kwe-ASTM A601 indlela yokwamkelwa
- Iirekhodi zonyango lobushushu (ukuba zikhankanyiwe), kubandakanywa ixesha lokufunxa, amazinga obushushu erempu, kunye nedatha yomoya we-furnace
- Ukuqinisekiswa kwezinto eziphathekayo kunye nokwakheka kweekhemikhali ezipheleleyo kunye neziphumo zovavanyo lomatshini (amandla okuqina, isivuno, ubude, ubunzima)
Oku asikobunjineli obugqithisileyo. Kukunciphisa umngcipheko. Enye impompo ye-OEM yaseMntla Melika ithintele i-220,000 yeedola zokukhumbula indawo ngenxa yokuba iskena sethu serediyografi sangaphambili sibambe indawo engaphantsi kombhobho we-AMS 5387-ebonakala kuphela kwithafa lesithathu lebhetshi yeprototype enamalungu amahlanu. Elo nqanaba lokuphonononga lisebenza kuphela xa kusenziwa, i-NDT, kunye ne-metrology zihlala phantsi kophahla olunye.
Amanyathelo alandelayo: Uyiqala njani iPrototype yakho Run Ekunene
Qala ngomzobo wakho-hayi ibhajethi yakho. Sithumelele i-STEP yakho okanye ifayile ye-IGES ene-callouts ye-GD & T, i-spec material, kunye neemfuno zokusebenza (umzekelo, "kufuneka utywine kwi-bar ye-350 ngaphandle kokuguqulwa"). Siza kuphendula ngengxelo eneenkcukacha ye-DFM, ixesha lokukhokela, kunye nesicatshulwa esiqinileyo-akukho bhaliso, akukho NDAs efunekayo kwasekuqaleni. Indawo yethu ehambelana ne-ISO eQingdao ixhasa iinxalenye zentsimbi ezinomthamo ophantsi okhawulezayo ukusuka kwi-2 kg ukuya kwi-85 kg, ngomatshini ogcweleyo we-CNC, unyango lobushushu, kunye nokugqitywa komphezulu okhoyo ngaphakathi endlwini. Ukuba isicelo sakho sifuna i-cobalt-nickel alloys, i-high-pressure integrity, okanye i-microstructure ephindaphindayo, qala ngokuqeqesha-ungalalani.
Iinjineli ezakha iisistim ze-hydraulic, i-oyile kunye nezixhobo zegesi, okanye izinto zobunjineli zezithuthi, ekunene iprototype yesanti yokugalela umzi-mveliso ayenzi nje iinxalenye. Iqinisekisa injongo yakho yoyilo-ngaphambi kokuba usike isixhobo sakho sokuqala sokuvelisa.
