Lapho onjiniyela bayacacisa ukufakwa kwensimbi ngomshini kumavalvu asebenza ngogesi, izindlu zokumpompa, noma izigxobo zewintshi, abagcini nje ngoku-oda ingxenye ethile—bazibophezela ekuzinzeni kobukhulu ngaphansi kwengcindezi yamabha angu-350, ubuqotho be-microstructural ngemva kokuhamba ngebhayisikili elishisayo, kanye nokuqedwa kwendawo okumelana nokuguga kokuguga emifudlaneni kawoyela egcwele isihlabathi. Sibone amaphrojekthi amaningi efa lapho abahlinzeki bempahla bephatha ukufakwa kwensimbi njengenqubo yempahla—bese benikezela ngomshini esitolo sezinkampani zangaphandle esinokutolikwa okungafani kwe-GD&T, amarekhodi okwelapha ukushisa okungahambisani, noma kungalandeleki amaqoqo wezinto ezibonakalayo we-ASTM A48 Class 350.
Kungani Ukufakwa Kwensimbi Emshinini Kuhluleka—Futhi Yini Empeleni Esebenzayo
Ukulingisa insimbi kukodwa akuqinisekisi ukusebenza. Ama-graphite flakes ensimbi empunga anikeza ukumanzi kodwa anciphisa amandla aqinile; I-ductile iron's spheroidal graphite ithuthukisa ukuqina kodwa idinga ukulawulwa okunembile kwe-nodularization ngesikhathi sokuthela. Engeza imishini ye-CNC—futhi wethula ama-vectors amasha ahlulekayo: ukuhlanekezelwa kwengcindezi eyinsalela kusukela ekupholiseni okungalingani, izimpawu zokuxoxa kuma-cylinder bores anezindonga ezincane, noma ama-gradients okuqina abangela ukuguga kwamathuluzi ngaphambi kwesikhathi lapho kuqedwa okokugcina.
Sake salungisa kabusha inqwaba yezindlu zesilinda sephampu ye-piston ngoba isisekelo sasebenzisa izinsalela ezitholiwe ngaphandle kokuqinisekiswa kwe-spectral. Ukuhluka kwe-silicon okwaba umphumela kushintshe ubulukhuni busuka ku-220–240 HB kuya ku-265 HB ezindaweni zendawo—obanele ukuphambukisa u-0.012 mm ngesikhathi sokuqeda isicefe. Kungakho sihlola konke ukuncibilika ngokuhlaziywa kwe-OES *ngaphambi* kokuthela—futhi siqinisekisa ubulukhuni bangemuva kokusakazwa ezindaweni ezintathu ngokusakazwa ngakunye, hhayi eyodwa kuphela.
Impumelelo yomhlaba wangempela incike ekuhlanganiseni okuqondile. I-Foundry, isitolo somshini, kanye ne-metrology kumele yabelane ngelogi eyodwa yomlando oshisayo, uhlelo olulodwa lwe-CMM, isitifiketi esisodwa sezinto ezibonakalayo. Awekho ama-handoffs. Akukho okucatshangwayo mayelana nezibonelelo "ezijwayelekile" zomshini. Uma ikhasimende lisithumelela umdwebo wepulaki ye-cobalt AMS 5387 ene-±0.005 mm yokubekezelela izimbobo zamadowels ayisithupha, siphendula emahoreni angu-48-hhayi nge-quote, kodwa ngombiko wokwenziwa obonisa lapho ukubhola kwe-EDM kudlula ukubhola okusontekile, lapho ukudambisa ingcindezi ngaphambi kokuba ama-roughing kuvimbela kanjani ukusebenzisa i-CONT'll kuvimbela ukubhoboza kwe-CONT. I-G2 ene-spindle ephethe umoya.
Okune Okungaxoxiswana Nge-Mission-Critical Iron Castings
- Ukulandeleka kokubalulekile kwehle kunombolo yokushisa-hhayi nje izitifiketi zokugaya, kodwa imibiko egcwele ye-OES, imigoqo yokuhlola eqinile egcinwe kungobo yomlando ngenkatho ngayinye, nezithombe ze-microstructure ziqinisekiswe ngokumelene ne-ASTM E112
- Ukuzivocavoca ngemuva kokunciphisa ukucindezeleka-Sibamba ama-castings ku-550 ° C amahora angu-4, bese sipholile ku-≤30 ° C / ihora ngaphambi kokuqala noma yikuphi ukukhishwa kwensimbi
- Ukuhlelwa kokuhlolwa kokuqala kwe-GD&T-Izinqubo ze-CMM ezakhiwe ngemidwebo yamakhasimende, hhayi izifanekiso ezijwayelekile; izici ze-datum ziphenywa kuqala, izindawo zokusebenza zigcina
- Ukuqinisekiswa kobuqotho bobuso-hhayi nje amanani e-Ra, kodwa ukutholwa kongqimba olumhlophe nge-SEM/EDS ukuze kube nobuso obubucayi obuvezwe kusevisi ye-H2S
Lapho Abahlinzeki Abajwayelekile Behla Kafushane (Nendlela Yokuyibona)
Abanye abathengisi bakhangisa “ukufakwa kwensimbi okunembayo” kodwa ukusakaza kwe-outsource ezindaweni ezingabizi kakhulu ezingenazo izilawuli ze-ISO 9001:2015 Isigaba somthetho 8.5.2 somkhiqizo ongavumelani. Abanye basebenzisa izinhlelo ezijwayelekile ze-CNC ezithatha imali yesitoko efanayo—inganaki ukuthi ukuhluka kokusakazwa kwesihlabathi kuthinta kanjani ukushuba kodonga kumajiyometri ayinkimbinkimbi njengamarola we-winch centre shaft roller.
Sibambe leli gebe phakathi nocwaningo lwakamuva: omunye oqhudelana naye ucaphune indikimba yevalvu yokucindezela enogqinsi oluncane oluyi-12-mm—kodwa umdwebo wabo wokulingisa ubonisa kuphela i-8-mm yemali encane. Empeleni, ama-30% ezingxenye ayedinga ukwakhiwa kwe-weld ngaphambi kokuthi kuqale ukusebenza. Lokho akukhona ukunemba. Lokho kuwukuqagela okufihliwe njengekhono.
Buza umphakeli wakho le mibuzo ngaphambi kokukhipha ama-PO:
- Ungangibonisa izingodo ezintathu zokugcina ezincibilikayo ze-ASTM A ductile iron?
- Yikuphi ukuchezuka kwakho okuphezulu okuvunyelwe phakathi kwesisindo somshini kanye nesisindo somshini wokugcina wesisekelo sepompo esingu-42 kg?
- Ingabe imibiko yakho ye-CMM ihlanganisa idatha yesinxephezelo se-thermal drift efakwe phakathi newindi lokuhlola lamahora angu-8?
Ukwakha Ukuzethemba—Hhayi nje Izingxenye
QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD. iletha ukufakwa kwensimbi ngomshini izixazululo lapho ukwethembeka kungaxoxiswana khona—hhayi ngoba sikufuna, kodwa ngoba inqubo yethu ishiya ubufakazi. Wonke amavalvu okucindezela ahamba anelebula enekhodi ye-QR exhunywe kudosi yayo yokuhlola egcwele: izitifiketi zempahla eluhlaza, amashadi okwelapha ukushisa, amafu ephoyinti le-CMM, kanye namamephu anobulukhuni obungaphezulu. Amakhasimende aseNyakatho Melika naseYurophu asebenzisa lawo mafayela ukuhlola ukuthobelana kwe-ASME Isigaba VIII Ingxenye UG-120. Ama-OEM aseNingizimu mpumalanga ye-Asia abhekisela kuwo ngesikhathi sokubuyekezwa kwe-APQP Stage 3.
Asijahi ivolumu. Sigxila ezingxenyeni lapho ukwehluleka kusho isikhathi sokuphumula, ubungozi bokuphepha, noma isijeziso esilawulayo—njengamabhomu e-T800 asekelwe ku-cobalt abamba usawoti oncibilikisiwe ongu-450°C ezitshalweni zelanga ezigxilile. Lapho, i-0.02-mm bore taper ayikona “ukuchezuka okuncane.” Ukungalingani kokugeleza okusheshisa ukuguguleka ngo-300%.
Ikusasa lingelezinqubo eziyingxubevange: ukwakheka kwe-investment-cast near-net enezindawo zokuvala ezisebenza ngomshini we-CNC, izindlu zokusakazwa kwesihlabathi ezinamashaneli okupholisa ahlanganisiwe aqedwe ngokugaya ngesivinini esikhulu. Sandisa i-R&D yethu ekubumbeni okupholisa okulawulwayo futhi sithuthukisa ukuqapha kokudlidliza okungaphakathi kwenqubo ukuze kutholwe ingxoxo ngesikhathi sangempela phakathi kwamabhulokhi amasilinda e-deep-hole.
Uma iphrojekthi yakho elandelayo idinga ukufakwa kwensimbi ngomshini lokho kuyiqiniso ku-300°C, ikwazi ukusinda emijikelezweni yokucindezela engu-10⁶, futhi ifika nezimanga ze-dimensional eziyiziro—qala ngokulandeleka kwezinto, hhayi intengo ngekhilogremu.
