Xa iinjineli ze-aerospace zifuna amacandelo otyalo-mali abambe ukunyamezela kwe-± 0.05 mm phantsi kwemithwalo ye-hydraulic ye-MPa ye-300, azihlali kwiziseko zenjongo jikelele. Bafuna i i-aero metals investment casting factory kunye nolawulo lwe-metallurgical olubhaliweyo, i-zero-batch drift kwi-AMS 5387 cobalt alloy, kunye ne-CNC-machine features ezihambelana ne-GD & T callouts-kungekhona nje imizobo. Kulapho ukuchaneka kuyeka ukuba yinkcazo kwaye ibe yinkqubo ephindaphindwayo.
Siye sabona iiprojekthi ezininzi zidodobala xa i-castings idlula iitshekhi ze-dimensional kodwa zisilela ukukhwela ibhayisekile eshushu ku-55°C ukuya +120°C ngenxa yokuba ubume beenkozo bungaqinisekiswanga bubushushu bangaphambili. Okanye xa indlu yempompo iqhekekile emva kweeyure ze-420 zomsebenzi oqhubekayo-kungekhona kwisiphene soyilo, kodwa ukusuka kwi-micro-porosity kufuphi nomhlaba we-pressure-seal oye watyibilika ekuhlolweni okubonakalayo okudlulileyo. Ezi ayizizo iimeko ezinzima. Bangumahluko phakathi "kwenqanawa" kunye "nokuhamba ngenqwelomoya." E-QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD., yonke i-cobalt-nickel investment casting iqala nge-T800 alloy billets eqinisekisiweyo, elandelekayo ukuya kwinani lobushushu, kunye neengxelo zespectrographic ezikhangelwe ngokuchasene ne-ASTM E1096 phambi kokunyibilika.
Indawo yabo ehambelana ne-ISO eQingdao ayiqhubi utyalo-mali njengomgca ozimeleyo-idibanisa ngokuqinileyo kunye ne-five-axis machining, isisombululo se-annealing, kunye novavanyo olungonakalisi. Umzekelo: umbhobho we-AMS 5387 awuphoswanga, emva koko umatshini, emva koko uhlolwe. Iphoswe nge-0.3 mm yesibonelelo somatshini kwiindawo ezibalulekileyo zokutywina; i-post-heat-treated in vacuum furnaces ilinganiswe yonke imihla; ukugqiba-oomatshini usebenzisa i-Renishaw-probed setups ebuyekeza ngokuzenzekelayo ukukhula kwe-thermal; kwaye ihlolwe ngee-CMM ze-Zeiss eziqhuba i-ASME B89.4.10-imilinganiselo ehambelanayo-ukulinganisa kungekhona nje ubungakanani, kodwa impazamo yefomu, ingqibelelo yomphezulu, kunye nobulukhuni bendawo. Oku kudityaniswa ngokuthe nkqo kuphelisa i-handoffs apho izitaki zokunyamezelana ziqokelelana. Izindlu zepiston pump cylinder zifika kwi-QA yokugqibela enembali epheleleyo-hayi nje ipasi / isitampu sokusilela.
Abanye banokuxoxa ukuba ukujulwa kwesanti kubonelela ngeendleko ezingcono kwizibiyeli ezinkulu zesakhiwo. Kodwa kwiindonga ezicekethekileyo, ezinomlinganiselo ophezulu we-aerospace manifolds-ingakumbi ezo zifuna amajelo okupholisa angaphakathi okanye iindlela zolwelo olusesikweni-utyalo-mali luhlala lungenakuthelekiswa. I-QIANGSENYUAN iqinisekisa oku ngokuvelisa rhoqo iintsimbi zensimbi ezingenasici kunye nobukhulu bodonga lwe-1.2 mm, i-0.8 mm ye-radii yangaphakathi, kunye ne-surface finishes phantsi kwe-Ra 1.6 µm-njengoko ihanjiswe, kungekhona i-post-polish. Inkqubo yabo yeqokobhe leceramic isebenzisa i-zircon-based slurries kunye ne-silica stucco edibeneyo, eyenza imijikelo yokutshiswa egcina iinkcukacha ezintle ngaphandle kokuqhekeka kancinci. Kwaye ngokungafaniyo neevenkile ezakha iqokobhe langaphandle, igumbi labo lonke lisebenza phantsi kobumanzi obungqongqo kunye nolawulo lobushushu (±2°C, 45–55% RH), kuba nokuguquguquka okungephi kobumanzi kutshintsha ukungenwa kweqokobhe-kwaye kuguqula isantya sokuhamba kwesinyithi ngexesha lokugalela.
Into ebahlulayo ayibobuchule kuphela—yindlela ababusebenzisa ngayo. Xa i-OEM ye-hydraulics yaseYurophu idinga imizimba yevalve yesiko engama-27 kwi-cobalt alloy ye-T800, abazange bacaphule nje ngokusekelwe kumthamo wemodeli ye-3D. Iinjineli zaphonononga amanqaku e-GD & T, iingozi ezinokubakho kwi-core-shift kwi-0.15 mm ye-datum feature, zicebise uhlengahlengiso oluncinci lwedrafti ukuphepha ukugaya okwesibini, kunye neengxelo zovavanyo lwezinto eziphathekayo ezibonisa amandla okuqina ≥1,380 MPa kwi-650 ° C-iqinisekisiwe nge-AMS 2269. Olo hlobo lokubandakanya i-prototyping rounds nge-prototyping rounds. Inkqubo yabo yokucwangcisa ebhityileyo ilandelela iodolo nganye ngokuchasene nexesha elililo lomjikelo-elingaqikelelwanga iiyure zomsebenzi-ngoko i-medium-volume ibaleka (50-300 pcs) ngenqanawa phakathi kweentsuku ze-12 zokusebenza, ngokuqhubekayo. Akukho "phantsi kokufumaneka kwezinto" amagatya. Ayimangalisi intlawulo ye-NRE yokuvunywa kwenqaku lokuqala.
Ukuba ukhangela izinto ezichanekileyo ze-aerospace apho ukusilela kuthetha ukwehla kwenkqubo-okanye okubi ngakumbi-udinga ngaphezulu komthamo wokuphosa. Udinga uqeqesho lwe-metallurgical, ukuqina kokuhlolwa okuhambelana neemfuno zakho zokusebenza, kunye nokulungelelaniswa kobunjineli ukusuka kuphononongo lokuzoba ngokupakishwa kokugqibela. An i-aero metals investment casting factory njengeQINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD. inikezela oko-kungekhona njengolwimi lwentengiso, kodwa njengobungqina benkqubo ebhaliweyo, izatifikethi ezithe ngqo kwibhetshi, kunye namalungu asebenza ngokufanayo kuwo onke amaqashiso emveliso. Inyathelo elilandelayo asikuko ukuthelekisa izicatshulwa. Yabelana ngephakheji yakho ye-GD&T kwaye ubuza: "Ungalindela phi indawo yokuqala yomngcipheko-kwaye uyenza njani?" Loo ncoko yahlula ababoneleli kumaqabane.
