I-Foundry casting ayikona nje ukugalela isinyithi esinyibilikisiweyo kwi-mold. Kulapho inzululwazi yezinto eziphathekayo idibana noqeqesho olulinganayo-kwaye apho ukunyathela ngendlela engeyiyo kuyilo lwepateni, ukukhetha ingxubevange, okanye izinga lokupholisa kunokubiza iiveki ekusebenzeni kwakhona, hayi iidola kuphela. Kwi-QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD., Siphose ngaphezulu kwe-12,000 yezindlu zevalve yoxinzelelo kunye neesilinda zempompo yepiston ukusukela ngo-2018-nganye ibambe ukunyamezelana okuqinileyo phantsi kwe-0.05 mm kunye nokusinda kwi-300 + bar hydraulic cycles. La mava asifundisa into ebalulekileyo: ukubunjwa kwesiseko esichanekileyo kuqala kwakudala ngaphambi kokuba iziko lilayite.
UYilo Lokukwazi Ukudlala—Ayisebenzi nje Kuphela
Iinjineli zihlala zilungiselela iinxalenye zokudityaniswa okanye ukuhanjiswa koxinzelelo — emva koko zikhuphe imizobo elindele ukuba iicaster “ziyenze isebenze.” Kodwa isanti kunye nokuphosa utyalo-mali kunemida enzima yomzimba. Sake safumana ifayile ye-CAD yendlu yepompo ye-cobalt-alloy ene-2.3-mm yodonga lwamacandelo kunye neembambo zangaphakathi ezihlukanisiweyo nge-4.7 mm. Inxalenye yaqhekeka ngexesha le-shakeout-kungekhona ekugaleleni kakubi, kodwa ngenxa yokuba i-gradients ye-thermal idlula i-window yokuqinisa i-AMS 5387. Sayila ngokutsha i-geometry yembambo, songeza iindawo ezibandayo zendawo, kwaye satshintsha umgca wokuqhawula nge-8 degrees. Isivuno sinyuke ukusuka kuma-62% ukuya kuma-98%.
Iitshekhi eziphambili esiziqhubayo ngaphambi kokucaphula:
- Ubuncinci becandelo lobungqingqwa: ≥4.5 mm yokujula intsimbi, ≥3.2 mm ialloyi cobalt-nickel njenge T800
- Umyinge weRadi ukuya eludongeni: Iikona zangaphakathi kufuneka zibe ≥0.6× ubukhulu bodonga olusondeleyo ukunqanda iinyembezi ezishushu
- Ukunyamezela okuphantsi: Iimbumba zesanti zinyamezela i-≤15 ° idrafti; iipateni zotyalo-mali zidinga ≥0.5 ° kwicala ngalinye-okanye i-CNC-machined cores
- Ukwahlulwa kophawu: Ziphephe iintloko ezicekethekileyo, ezizimeleyo okanye iiflanges-ziphola ngokukhawuleza, zikhuphe izinto ezininzi, kwaye zivule iindlela ezincinci zokushwabana.
Ukuba i-GD&T yakho ifuna indawo yokwenyani kuphawu oluphoswe ngqo kumngundo, qinisekisa ukuba loo ndawo iya kwenziwa ngomatshini emva kokuphoswa. Sisebenza ngomatshini i-87% yentsimbi yethu kunye neentsimbi zokuphoswa kwentsimbi ukuya kwi-spec yokugqibela-kuba indawo ephosiweyo ayifane ibambe ± 0.1 mm ukuchaneka kwendawo kwi-300 mm.
Ukukhetha kwe-alloy Kutshintsha yonke into-Ingakumbi xa ungenakuyisebenza kamva
I-cobalt-nickel alloys njenge-AMS 5387 okanye i-T800 ayikhethwanga kwi-aesthetics. Zicaciswa xa zixhathisa ukhukuliseko, amandla okurhubuluza ngaphezulu kwe-650 ° C, okanye imicimbi yokusebenza engeyiyo eyemagnetic-njengakwimibhobho ye-oyile kunye nerhasi ephuma kumngxuma wemibhobho okanye iiroli ze-winch ze-high-speed centre shaft rollers. Kodwa ezo zakhiwo zifanayo zibenza nzima ngenkohlakalo ukwenza umatshini emva kokuphoswa. Iplagi enye ye-T800 ithatha iiyure ezili-11.2 zokusila nge-multi-axis kusetyenziswa isixhobo se-PCD kunye ne-cryogenic coolant. Ke ukuba inxalenye yejiyometri ivumela, sidibanisa i-machining kwinkqubo yokuphosa ngokwayo-ukongeza imingxuma yedowel yendawo, iipads zedatum, okanye i-partial bore preforms ngqo kwipatheni yotyalo-mali.
Sikhupha zonke ii-ingots ze-superalloy ngeengxelo ezipheleleyo zovavanyo lwe-mill (MTRs) ezinokulandeleka kwinombolo yobushushu kunye nohlalutyo lweekhemikhali. Akukho bhetshi ingena ezikweni ngaphandle kokuqinisekiswa kwe-spectrographic. Ngoba? Ngenxa yokuba ukuphambuka kwe-0.03% kumxholo wekhabhoni kwi-T800 kutshintsha ubunzima bayo be-cast-cast ukusuka kwi-32 HRC ukuya kwi-41 HRC-ngokwaneleyo ukutshabalalisa i-carbide ifake i-mid-cut.
Umgangatho awuhlolisiswanga-Yakhelwe ngaphakathi, iLayer ngoMaleko
Uninzi lwabaseki bahlola ukujulwa kumanqaku amathathu: imathiriyeli engenayo, idimension erhabaxa emva kokushukuma, kunye nokukhangela okubonakalayo kokugqibela. Songeza ezinye ezine:
- Ukuskena ingqibelelo ngundo: I-X-ray tomography kwi-100% ye-investment shell molds ngaphambi kokuba i-dewaxing
- Galela log lobushushu: Idatha yexesha langempela le-thermocouple engqanyaniswe kwinani ngalinye lobushushu
- Imephu yobulukhuni becandelo: I-12-point Rockwell C ufundo kuwo wonke amacandelo anqamlezayo kwiqashiso ngalinye
- I-hydrotest esebenzayo: Yonke imizimba ye-valve yoxinzelelo iphantsi kwe-1.5 × imilinganiselo yoxinzelelo ibambe imizuzwana ye-120-ngokubona ukuvuza kwe-0.003 cc / min
Sigcina umkhondo ogcweleyo-kungekhona nje uphicotho, kodwa ngenxa yokuba xa umthengi ebika ukukhathala kokuqhekeka kwiiyure ze-14,200 zokusebenza, sinokutsala i-log yokuthulula yasekuqaleni, i-curve yokupholisa, kunye nemephu yobunzima bonyango emva kokushisa ngaphantsi kwemizuzwana engama-90. Eso santya sahlula ulungiso lwengcambu kuqikelelo.
Kutheni iHybrid Casting + Machining Ibetha Nokuba yodwa
Ezinye iivenkile ziphatha i-casting kunye ne-CNC njengamanyathelo alandelelanayo. Sibaphatha njengezifundo ezidibeneyo. Izindlu zethu ze-cylinder ziqala njenge-santi-cast cast ductile iron blanks-kodwa umphezulu webhore awugqitywanga ngokujika. Iphoswe ngesibonelelo sobukhulu obuyi-0.8 mm, emva koko ihonjiswe *kwindawo enye* esetyenziselwa ukugaya i-CNC yokugqibela yobuso obunyukayo kunye nemicu yezibuko. Oko kuphelisa ukutshintshwa kwedatums-induced fixture-kwaye kubambe ukugxila phakathi kwe-ID kunye ne-flange OD ukuya kwi-0.015 mm ngaphesheya kwe-280 mm ubude.
Oku kuqukunjelwa kokuhamba komsebenzi kusenza sikwazi ukuhambisa amacandelo afana ne-winch shaft rollers ezineejenali ezithwele umhlaba * kunye * namazinyo egiya ephosiweyo-zombini zidibana ne-ISO 2768-mK yokunyamezelana ngokubanzi, kodwa zabelana ngembali enye yobushushu kunye nolwakhiwo lwezinto eziziinkozo. Akukho unyango lwesibini lobushushu. Akukho mngcipheko wokuphazamiseka. Ukuhamba nje kwemveliso enye, irekhodi enye yomgangatho, umhla omnye wokuhanjiswa.
I-Foundry casting iphumelela xa i-metallurgy, ijometri, kunye nenjongo yokuvelisa ilungelelaniswa-hayi xa kuxoxwa ngokwahlukeneyo. E-QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD., Asazi nje isinyithi. Sibeka ukuzithemba-kuzinzo lwe-dimensional, imfezeko yesakhiwo, kunye nokusebenza okuphindaphindiweyo phantsi koxinzelelo. Nokuba uchaza isiseko sempompo yentsimbi engatyiwayo okanye ufanelekile umbhobho wengxubevange ye-cobalt kwinkonzo egqithisileyo, ilungelo ukwenziwa kwesiseko iqabane alilindi umzobo wakho. Bayanceda ukuyibhala.
