Xa iinjineli zichaza imveliso yokubumba imveliso yesitofu yesinyithi yeendawo ezichanekileyo ezichanekileyo, ayiyonto nje yokukhangela izinto-zikhusela uzinzo phantsi kwe-120 MPa yomthwalo we-hydraulic, ukuhambelana kwe-microstructural kwiibhetshi zeeyunithi ezingama-500, kunye nokunyamezela umphezulu we-zero imfezeko kwimibhobho ye-cobalt-alloy. Leyo yinyani yokusebenza-hayi ulwimi lokuthengisa. Sibone iiprojekthi ezininzi kakhulu zimile kwinqanaba lokuphononongwa kwe-GD&T kuba umthengisi uphathe i-AMS 5387 "njengenye ialloy." Impumelelo yehlabathi yokwenyani iqala ngokwazisa ngokuziphatha, hayi amanani ekhathalogu.
Kutheni isitofu sesinyithi sokubumba sisodwa akwanelanga kwiMishini-Amacandelo abalulekileyo
I-Metal injection molding (MIM) iyagqwesa kubunzima obuyi-net-shape: iindonga ezibhityileyo, ii-undercuts, iintambo ezicolekileyo. Kodwa izindlu zempompo zemizi-mveliso, imizimba yevalvu yoxinzelelo, kunye ne-winch center shaft rollers zifuna ngaphezulu kwejometri. Zifuna ubume obuziinkozo obulawulwayo emva kokuntywila, ukugqwetheka okunokuxelwa kwangaphambili ngexesha lonyango lobushushu, kunye nokuqina komphezulu okusinda ukuhamba kwe-abrasive slurry-ngaphandle kwe-post-sinter machining ebeka esichengeni i-gradients yoxinaniso. Kulapho udibaniso oluthe nkqo luba lungenangxoxo.
Siye sadibana neendlela ezintathu zokusilela okuphindaphindiweyo kubaboneleli be-MIM kuphela:
- Idimensional drift ngaphaya ±0.05 mm kwibhore yesilinda emva kokuthotywa koxinzelelo
- Amaqela e-Micro-porosity kwiifayili ezithwala imithwalo, ezibangela ukukhathala kwangaphambi kwexesha
- Impendulo engahambelaniyo ye-cobalt-nickel alloy kwi-HIP (i-isostatic eshushu icinezela), ibangela ukuguquguquka kwebhetshi ukuya kwibhetshi kumandla esivuno.
Ukulungiswa akukho ngcono iMIM yodwa. Idibanisa i-MIM kunye nokugqiba kwe-CNC echanekileyo, unyango lobushushu obulawulwayo, kunye nokuqinisekiswa kwe-CMM ye-optical kuwo wonke umjikelo we-thermal. Yiloo ndlela ovala ngayo ukuchaneka kokwenyani kokusebenza-hayi nje ukuchaneka kwezithambiso.
IiLevers ezine zobuGcisa eziHambisa inaliti
Ayingabo bonke abavelisi bamacandelo esinyithi abalawula izinto ezifanayo. Nantsi into eyahlula ukusebenza okuphindaphindwayo kwiziphumo ezinethemba:
- Ukulandelelwa kweMathiriyeli ukuya kwiNani lobushushu: Yonke inxalenye ye-T800 esekelwe kwi-cobalt ithwala uhlalutyo olubhaliweyo lwe-melt, kubandakanywa i-nitrogen eseleyo kunye nomxholo we-oksijini-ibaluleke kakhulu ekukhuseleni ukubola kwiindawo zegesi ezimuncu. Akukho “ziqinisekisiweyo ukuba zixelwe” iindlela ezimfutshane.
- Ukuqinisekiswa kweNkqubo yeHybrid: Kumalungu empompo ye-AMS 5387, siqinisekisa ulandelelwano olupheleleyo: Inxalenye eluhlaza ye-MIM → ukubopha → i-sintering → HIP → rhabaxa i-CNC → ukuphatha ubushushu → gqiba i-CNC → ukugqitha komphezulu. Inyathelo ngalinye lichaze iiparameters-kwaye ukutenxa kubangela ukubamba ngokuzenzekelayo.
- UHlolo oluSebenzayo, hayi nje iitshekhi ezinoMda: Izindlu ze-piston pump cylinder ziphantsi kovavanyo lwe-hydrostatic kwi-1.5 × ingcinezelo yokusebenza ngaphambi kokuthunyelwa. Iplagi ye-cobalt alloy ifumana ukuskena kwe-ultrasonic kwi-subsurface discontinuities-hayi nje ingxelo yokulungelelanisa.
- GD & T-Aware Machining Setup: Iinkqubo zethu ze-CNC ze-multi-axis zihlonipha ukubaluleka kwedatum. Ukuba umzobo wakho ubiza unyamezelo lwendawo xa kuthelekiswa nenqwelomoya yesibini, izixhobo zethu zinyanzelwa ngokwasemzimbeni loo nqwelomoya kuqala-akukho ngqikelelo, akukho kuphinda kusetyenzwe.
Yintoni iiNjineli ezingayihoyiyo xa zichaza "Ukuchaneka okuphezulu"
Abanye banokuphikisa ukuba ukunyamezelana okungqongqo ngokuzenzekelayo kuthetha iindawo ezingcono. Nangona kunjalo, ukucacisa ukunyamezela ngaphandle kokuqwalasela umxholo wokusebenza kuqhuba iindleko-kunye nomngcipheko. Ubukhulu obuyi-±0.01 mm kumphathi onyusayo ongabalulekanga akongezi xabiso. Kodwa ubambe ±0.005 mm kwindawo yokutywina yesitulo sevalvu? Oko kuthintela ukhukuliseko olubangelwa yi-cavitation kwi-3,000 RPM.
Sihlala siphawula olu rhwebo ngexesha lophononongo lobunjineli:
- Ukutshintsha isiseko sesanti-cast nge-MIM kunengqiqo kuphela ukuba ukunciphisa ubunzima kunciphisa i-22% yexabiso eliphezulu leyunithi-kwaye kuphela ukuba isicelo sigwema ukuhamba ngebhayisikili eshushu ngaphezu kwe-400 ° C.
- Ingxubevange ye-T800 inikezela ukuxhathisa okungaphezulu kokunxiba, kodwa ubuchule bayo behla nge-60% xa kuthelekiswa nomgangatho wama-316. Siza kucebisa olunye ulandelelwano lukhuni okanye unyango lwasekhaya lwasekhaya ukuba i-output ibaluleke ngaphezu kobunzima obukhulu
- Iimfuno zokugqiba umphezulu kufuneka zihambelane nezinto eziguquguqukayo zolwelo: iRa 0.4 µm kwiindlela zokuqukuqela zangaphakathi zehlisa isiphithiphithi; I-Ra 3.2 µm kwimigangatho yokunyusela yangaphandle igcina i-37% kwixesha lokugqiba
Ukucaca apha akusiyo inkonzo-kukunciphisa umngcipheko. Ngenxa yokuba indleko yokwenyani ayiyokowuti. Kukulibaziseka kweeveki ezisibhozo xa iiyunithi zokuqala ezingama-50 zingaphumeleli kuvavanyo olusebenzayo.
Ukwakha Ukuchaneka Okusebenzayo-Akukoneli Nje Ukudlula Uhlolo
Umzi-mveliso wokubumba imveliso yesitofu sesinyithi ufumana ukuthenjwa ngoqeqesho oluphunyeziweyo—hayi izatifikethi eludongeni. Ukuthotyelwa kwe-ISO kubalulekile kuphela xa iguqulela kwiirekhodi zokuhlola ezibhaliweyo kwiqashiso ngalinye, ukulandeleka okupheleleyo kwemathiriyeli ukubuyisela kwi-ingot mill, kunye ne-zero ngaphandle kwe-100% yeprothokholi yokuhlola ebonakalayo yeendawo ezibaluleke kakhulu zokutywinwa.
QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD. isebenza ngolu hlobo kuba iinkqubo zehydraulic azixoleli ukuxinana okungahambelaniyo. Ioyile kunye neevalvu zegesi azinyamezeli i-micro-porosity kufuphi nemida yoxinzelelo. Iifestile zeemoto zobunjineli azikwamkeli ukukhukuliseka komda emva kokuhamba ngebhayisekile eshushu.
Yiyo loo nto ugxininiso lwazo luhlala lumxinwa: iivalvu zoxinzelelo, iisilinda zezindlu, iziseko zempompo, kunye neeshafti zewintshi—hayi “zonke iinxalenye zentsimbi.” Ubunzulu bubetha ububanzi xa ubomi kunye nezixhobo zixhomekeke ekuthembekeni. Indaleko yabo elandelayo-i-R&D kwiinkqubo ezixutyiweyo zokuphosa-ayiyi kuleqa into entsha. Iya kusombulula i-bottleneck elandelayo: ukunciphisa ixesha lokukhokela kumacandelo e-AMS 5387 ngaphandle kokuncama ukuphindaphinda kwe-HIP.
Ukuba iprojekthi yakho ifuna iinxalenye ezenza phantsi koxinzelelo, hayi ukujonga ngokuthe ngqo ephepheni, qala ngoqeqesho lwenkqubo-hayi nje uluhlu lwamakhono.
