Xa iinjineli zichaza a isiseko sokulahla kwiingxenye zetsimbi ezichanekileyo, azigcini nje ngokuyalela isinyithi-zibophezela ukuzinza kwe-dimensional phantsi koxinzelelo lwe-bar ye-300, ukunyaniseka kwe-microstructure emva kokuhamba ngebhayisikili yokushisa, kunye nokunyamezela kwe-porosity kwi-cobalt alloy nozzle. Leyo yinyani esiyibona imihla ngemihla kwi-Qingdao Qiangsenyuan Technology Co., Ltd-umenzi apho "ukuchaneka" kungelona lwimi lokuthengisa. Yeyona mfuno isezantsi isitampu kuyo yonke ingxelo yohlolo.
Kutheni ukwenza izigqibo ze-Foundry zisilela ngaphambi kokuba kuqale uMatshini
Siye saphonononga imizobo yabathengi abangaphezu kwe-180 kulo nyaka uphelileyo-kwaye i-63% iqulathe ungquzulwano lwe-castability olufihlwe kwi-callouts ye-GD&T. Umzekelo oqhelekileyo: ukucacisa ± 0.05 mm isikhundla sokwenyani kwisiseko sempompo yesanti ye-420 mm ububanzi, ngelixa ifuna i-AMS 5387 cobalt alloy kunye ne-Rm ≥ 1,250 MPa. Olo kudibanisa lufuna ukuqina okulawulwayo, ukupholisa umkhombandlela, kunye noxinzelelo lwasemva kokuphoswa-akukho nanye kuzo iivenkile ezisemgangathweni ezibeka iliso kwinkqubo. Isiphumo? I-Warpage ngexesha lokugqitywa kwe-CNC yokugqibela, iibhetshi ezichithiweyo, kunye nokulibaziseka kokuhanjiswa okuhamba kuyo yonke imigca yendibano ye-OEM.
Ulungiso luqala phezulu. Kwiziko lethu elithobela i-ISO eQingdao, ukuphoswa akuyonkqubo yokuzimela-yinto yokuqala yolandelelwano oludityanisiweyo ngokuqinileyo: uyilo lwepateni → ukulinganisa ukungunda → ukuqinisekiswa kwebhetshi yesinyithi → ukubekwa esweni kwe-thermal → I-CMM-ingqinisiswe njengejiyometri. Siqhuba imodeli yokuqinisa kuyo yonke indawo entsha, sibonisa iindawo ezishushu ngaphambi kokugalelwa kokuqala. Kwizindlu ze-piston pump cylinder, oko kuthetha ukulungelelanisa i-geometry ye-gating ukuphelisa i-shrinkage kwindawo ye-valve port-ukunciphisa ukusebenza kwakhona ukusuka kwi-12% ukuya ngaphantsi kwe-2%.
Apho i-Cobalt Alloys yahlula ii-Foundries zokwenyani kubathengisi
Amacandelo e-cobalt-nickel-ingakumbi i-AMS 5387 kunye ne-T800 amabakala-abonisa izithuba zokukwazi ngokukhawuleza. Ezi ngxubevange azixhathisi nje umhlwa; baxhathisa umatshini, baxhathise ukufana konyango lobushushu, kwaye baxhathise ikhemistri yomthengisi engahambelaniyo. Sifumana imathiriyeli ekrwada kuphela kwii-mills ezinokulandeleka kweladle epheleleyo kwaye senza uhlalutyo lwe-OES kuyo yonke ikhoyili engenayo. Kodwa i-chemistry yodwa ayiqinisekisi ukusebenza. Kwenye iprojekthi yamva nje, i-OEM yaseYurophu ye-hydraulic ibike ukuqhekeka kwangaphambi kwexesha kwiiplagi ze-cobalt alloy. Uphononongo lwethu lwe-metallurgical lubonakalise unobangela osisiseko wawungengokwakheka-yayingalawulwayo i-delta ferrite formation ngexesha lokufakwa kwesisombululo. Sihlengahlengise ixesha lokufunxa kunye nesantya sokupholisa, emva koko saqinisekiswa ngemephu ye-SEM/EDS. Ukuchasana nokuqhekeka kuphuculwe nge-300% kuvavanyo olusebenzayo.
Yiloo nto ukudibanisa ngokuthe nkqo kubalulekile. Xa ukuphosa, unyango lobushushu, kunye ne-5-axis machining kwenzeka phantsi kophahla olunye, ulawula iinguqu ezichaza ukuthembeka: umkhombandlela wokuhamba okuziinkozo ngokunxulumene neendlela zokulayisha, ukusabalalisa uxinzelelo olushiyekileyo ngaphambi kokusikwa kokugqibela, kunye nokuthembeka komphezulu emva kokudubula. Kwiirola ze-winch yemoto yeziko lobunjineli, oko kuthetha ukulungelelanisa ukukhula kwe-dendrite ngokuhambelana ne-torque axis-kunye nokuqinisekisa nge-ultrasonic anisotropy scans.
“Ukuchaneka” Kuthetha ntoni Enyanisweni xa Uziqhelanisa
Ukuchaneka akulonani kumzobo. Yindlela obambe ngayo ngokungaguquguqukiyo ukuguquguquka kodonga lwe-0.025 mm ngapha kwe-270 ° yomzimba wevalve yoxinzelelo. Ifezekisa iRa ≤ 0.8 µm kwiipaseji zangaphakathi ngaphandle kokupholisha okwesibini. Ikhupha i-98% yesivuno sokuqala kwiijiyometri ezingekho mgangathweni njengemilomo ye-cobalt ene-tapered enamacandelo eludongeni ayi-0.3 mm.
- Ulawulo lomgangatho: Ugutyulo olupheleleyo lwe-CMM kuzo zonke iinkalo ezibalulekileyo, kunye nengxelo ezenzekelayo ebotshelelwe kwimigangatho ye-ASME Y14.5
- Ukuqinisekiswa kwezinto: Iqela lezatifikethi zokuthotyelwa, kubandakanywa ukuqina, impembelelo, kunye nedatha yovavanyo lwe-intergranular corrosion
- Ukuqinisekiswa okusebenzayo: Uvavanyo loxinzelelo ukuya kwi-1.5 × uxinzelelo lokusebenza, kunye nedayi yokungena okanye i-UT kuzo zonke iindawo ezinoxinzelelo oluphezulu
- Ukulandeleka: I-Laser-etched part IDs edityaniswe nezigodo ezinyibilikayo, iitshati zokuphatha ubushushu, kunye neerekhodi zokuhlola
Asikhupheli nayiphi na kwezi. Yonke into eyenziwe ngentsimbi, ukujulwa kwentsimbi, kunye nentsimbi engenastainless idlula kwilebhu yethu esemgangathweni-hayi uluhlu lokuhlola lomphicothi zincwadi lomntu wesithathu.
Ukukhetha ngaphaya kweXabiso: IFactor yeNqinisekiso yokuhanjiswa
Ucaphulo lwamaxabiso alufane lubonise umngcipheko. I-quote ye-$ 28 / kg ye-stainless steel casting ibonakala inyanzelekile-ude ufunde ukuba ivenkile ayinakho amandla otyalo-mali kunye ne-subcontracts cores complex cores. Oko kongeza ixesha lokukhokela iiveki ezintathu kwaye yazisa ukungaphumeleli kojongano. E-Qingdao Qiangsenyuan, amaxesha eprototype-ukuya-kwimveliso aqikelelwa ngenxa yokuba singabanini bezixhobo, iziko, kunye nokulungelelanisa oomatshini bokulinganisa. Kwii-odolo ezinomthamo ophakathi (i-50-500 iipcs), ukuhamba kwethu okuthe tye kuzisa ngaphakathi kwe-± 5 iintsuku zeentsuku ezizibolileyo-eziqinisekisiweyo kwii-217 zokuthunyelwa kunyaka ophelileyo.
Olo qikelelo luvela kwintsebenziswano yobunjineli obucwangcisiweyo. Asilindi ukuba imizobo ibe "yokugqibela." Ngexesha lophononongo loyilo lwangethuba, iqela lethu libonisa imiba yokwenziwa kwezinto: ii-engile eziyidrafti azinzulu kakhulu kumngundo wesanti, iradio iqine kakhulu ukuba ingasuswa, okanye izikimu ze-GD&T ezingqubana neepateni zokucutheka. Omnye umenzi wempompo waseMntla waseMelika unciphise umjikelo wophuhliso nge-40% emva kokwamkela le nkqubo yophononongo lwangaphambili.
Kubathengi bemizi-mveliso abafumana izinto zentsimbi ezichanekileyo, ekunene isiseko sokulahla ayichazwanga ngokwezikweri okanye iitoni zonyaka. Ichazwa ngokuba iqonda nzulu kangakanani iindlela zakho zokungaphumeleli-kwaye ilwakha ngokungqongqo kangakanani uthintelo kuwo onke amanyathelo. Nokuba ufuna iivalvu zoxinzelelo ezibambe iibhari ezingama-400, ingxubevange ye-cobalt iimpompo ezi-6 ezisinda eludaka oluludaka, okanye iijometri zesiko ze-T800 ezifuna ukomelela kunye nokusebenza kakuhle-siqala ngemeko yakho embi kakhulu kunye nenjineli ngasemva. Ukuchaneka kuqala apho iingqikelelo ziphela.
