Xa iinjineli zifuna isakhono sotyalo-mali oluncinci lwefektri yezahlulo ezingaphantsi kwe-50 mm ezine-±0.02 mm zokunyamezela kunye nokugqitywa komphezulu ngaphantsi kwe-Ra 1.6 µm, uninzi lwababoneleli babethe udonga. Siye sayibona ngokuphindaphindiweyo: iiprototypes zilibaziseke kwiiveki ezintandathu, ukulahlwa kwaliwe ngenxa ye-micro-porosity kwiindlela ezihamba phambili, okanye imilomo ye-cobalt alloy ehlulekayo kuvavanyo loxinzelelo emva konyango lobushushu. Leyo ayisiyongxaki yezixhobo-yingxaki yokulungelelanisa inkqubo.
Ukulahlwa koTyalo-mali oluNcinci lufuna Ngaphezulu kokungunda okuncinci
Utyalo-mali oluncinci lokwenyani ayikokutyalomali “okuncinci” nje. Ifuna ulawulo olungqongqo kwi-shrinkage yepateni yewax, iqokobhe le-ceramic permeability, i-metal superheat, kunye nesantya sokuqina-ingakumbi xa kusenziwa izinto ezinodonga oluncinci (0.8-2.5 mm) ukusuka kwi-AMS 5387 cobalt alloy okanye i-T800-based superalloys. Abasunguli abasemgangathweni bahlala betsiba imodeli yangaphambi kwemveliso yobushushu okanye basebenzise iiresiphi zeqokobhe elenziwe lafana nelo. Kwi-QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD., wonke umsebenzi we-micro-casting uqala ngokulinganisa okuqinisekisiweyo okuqiniswayo-kungekhona njengebhokisi yokukhangela, kodwa ukuqikelela apho uxinzelelo olushiyekileyo lugxininise kwi-plug ye-12-mm-diameter yepompo kunye nemijelo yangaphakathi yokupholisa.
Sakhe saqhuba ii-iterations ezintathu zesitulo sevalve ye-hydraulic ngaphambi kokutshixa i-slurry viscosity, ixesha lokuhlala le-dip, kunye neprofayili yendlela ye-dewaxing. Umehluko? Ukunciphisa i-40% kwi-microporosity kwi-junction yesango-kuqinisekiswe nge-X-ray CT scan, kungekhona nje ukudaya ukungena. Yiloo ndlela ufezekisa ngayo ingqibelelo yokusebenza kwiindawo ezisebenza kwi-350 bar kunye ne-180 ° C.
Kutheni udibaniso oluthe nkqo lubetha ukuCasa ngaphandle + koMatshini
Abanye abavelisi baphosa okungenanto, emva koko bayithumele kwivenkile ye-CNC. Kodwa izinto ezincinci ezifana ne-0.3-mm radial grooves kwi-piston pump cylinder yezindlu zifuna machining *phambi* konyango lobushushu lokugqibela-kungenjalo, ukugqwetheka kutshabalalisa ukuthotyelwa kwe-GD&T. Abanye baqala ngomatshini, bandule ke bajike bafake izinto ezifakwayo—ukwazisa i-efacial voids.
I-QINGDAO QIANGSENYUAN iphatha zombini kwindawo enye ehambelana ne-ISO. Umzekelo: i-cobalt-nickel alloy winch center shaft roller iqala njenge-investment-cast kufuphi-net shape, ingena kwisisombululo se-annealing, ifumana ukuchaneka-iguqulwe kwi-5-axis ye-DMG Mori kunye ne-in-process laser probing, emva koko ifumana i-hard-chrome plating kunye nobukhulu obulawulwayo (25-35 µm crossified by µm). Akukho handoffs. Akukho bhetshi idibanisayo. Akukho ukulandeleka okulahlekileyo.
- Amaziko omatshini e-CNC alinganiswe imihla ngemihla ukuya kwimigangatho ye-ISO 230-2
- Imingundo yeqokobhe yomiswe kumagumbi alawulwa kukufuma (RH < 35%) phambi kokudubula
- Zonke i-cobalt alloys ezifunyenwe ngeengxelo zovavanyo olupheleleyo (MTRs), kubandakanywa ubungakanani beenkozo kunye nohlalutyo lokusabalalisa i-carbide
- Inxalenye nganye efakwe kwimephu ngedatha yeCMM ebotshelelwe kwinani layo lobushushu
Imida Yehlabathi Lokwenyani—Nendlela Yokusebenza Ngaphakathi Kuyo
Ukuphoswa kotyalo-mali oluncinci ayisiyomlingo. Ubukhulu bodonga obungaphantsi kwe-0.6 mm bubeka umngcipheko wokuzaliswa kokungunda okungaphelelanga. Iimpawu ezincinci kuno-0.2 mm azifane ziphile ekususweni kweqokobhe ngaphandle kokukhukuliseka. Kwaye ewe-i-AMS 5387 iyancipha i-1.92% ngokuqhelekileyo, kodwa i-shrinkage yendawo ingahluka ± 0.15% kuxhomekeke kubunzima obusondeleyo. Abanye abathengi bacinga ukuba "micro" ithetha "akukho yilo." Ayilunganga. Nokuba idrafti ye-0.5 ° igcina ubomi besixhobo kwaye inqanda ukuqhekeka kweqokobhe ngexesha le-dewaxing.
Yiyo loo nto iiflegi zethu zophononongo lobunjineli ziyila imigibe kwangethuba: iikona zangaphakathi ezibukhali ezibangela iinyembezi ezishushu, iimbambo ezibhityileyo ezingaxhaswanga eziwayo ngexesha lokudinwa, okanye ukwandiswa kobushushu obungahambelaniyo phakathi kwe-cobalt alloy kunye nokufakwa kwentsimbi engatyiwayo. Asithi "ewe" kuwo wonke umzobo-sibuza "Yeyiphi imithwalo ebonwayo? Yeyiphi indlela yokusilela?" Emva koko sihlengahlengisa i-gating, silungise izinyusi, okanye sicebise indlela ye-hybrid cast-and-brazed.
Enye impompo ye-OEM yaseYurophu yaphinda yaqulunqa ijiyometri ye-nozzle yayo emva kwengxelo yethu yokwenziwa-ukunciphisa isivuno sokuphosa ukusuka kwi-68% ukuya kwi-94%, kunye nokuphelisa imisebenzi emibini yokusila. Iindleko ngenxenye yehle ngama-22%. Ixesha lokukhokela liye lacutheka ukusuka kwi-14 ukuya kwiiveki ezisi-9.
Ukukhetha i-Micro Investment Casting Factory kuthetha Ukukhetha iQela leNkqubo
Umzi-mveliso othembekileyo wotyalo-mali oluncinci unikezela ngaphezulu kokuthotyelwa komgangatho. Ihambisa i-metallurgical consistency kuwo wonke amaqhekeza angama-500. Ibamba i-Ra 0.8 µm kwiibhore zangaphakathi ngaphandle kwe-honing yesibini. Ilanda yonke igram ye-T800 alloy ibuyele kwi-melt log yayo-hayi nje i-ID yebhetshi. Iqinisekisa iiprothokholi zokuhlola ngokuchasene ne-ASME Y14.5 kunye ne-EN ISO 1101, hayi nje amanqaku e-PO yomthengi.
QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD. isebenza ngolu hlobo kuba iinkqubo zoxinzelelo oluphezulu lwehydraulic, izixhobo ze-oyile ezikude nonxweme, kunye neefestile zemoto ezinobunjineli zinyamezela ukuthotyelwa kweqanda. Xa icandelo lakho lilawula ukuhamba kwamanzi kwivalve ye-subsea, "ivale ngokwaneleyo" ayikho.
Khangela ulawulo lwenkqubo ebhaliweyo—hayi iincwadana. Cela isampulu yengxelo yeCMM ene-GD&T callouts. Cela ubungqina besakhono sokunyanga ubushushu bangaphakathi kunye nesatifikethi sesithando somlilo. Qinisekisa ukuba ingaba ngabanini balebhu yeqokobhe labo okanye i-outsource prep slurry. Kwaye soloko uvavanya ukuphendula kwabo kwiprototype encinci eqhutywayo ngaphambi kokuzibophelela kwivolumu.
Ikamva leleefektri eziphatha utyalo-mali oluncinci njengoqeqesho oluqhutywa yifiziksi—hayi umsebenzi wokwehlisa. Oko kuthetha ukuba ubunzulu be-R&D kwiinkqubo zokugalela eziphantsi-zidubedube, i-AI-incediswe kwiqokobhe loqikelelo lwesiphene, kunye neenkqubo ezixubeneyo ezidibanisa utyalo-mali kunye ne-laser ekhethiweyo yokunyibilika kwiimpawu ezinqabileyo kakhulu. Ukuba iprojekthi yakho elandelayo ifuna ukuchaneka kwecandelo elincinci lokwenziwa apho i-microstructure, ijometri, kunye nomsebenzi awunakuthetha-qala ngenkqubo engqongqo, hayi ixabiso.
