Xa iinjineli zicacisa inxalenye emele ibambe ukunyamezela kwe-± 0.01 mm phantsi kwe-350-bar ye-hydraulic pressure-kwaye iphile kwi-10,000 + imijikelezo kwi-slurry e-abrasive-ayifuni nje i-Foundry. Bafuna i Umzi-mveliso wokugalela imali we-IMPRO ephatha isinyithi njengekhowudi kunye nozinzo lwedimensional njengomthetho wekhontrakthi.
QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD. isebenza esinye seziko eQingdao-hayi njengevenkile yentsimbi eqhelekileyo, kodwa njengeqabane elichanekileyo lezinto ezibalulekileyo zobuthunywa apho ukusilela kungabizi kakhulu-yintlekele. Sibone abathengi bebuya kathathu kunye nomzobo ofanayo we-AMS 5387 we-cobalt wempompo ye-cobalt yezindlu: okokuqala kwi-porosity yezinto kwi-radius yesitulo sevalvu, okwesibini ngenxa ye-microcracking emva konyango lobushushu, okwesithathu ngenxa yokuba ukugqiba komphezulu akuzange kuhlangane ne-specs yokulinganisa ukuhamba. Ngalo lonke ixesha, unobangela wawungengo "umgangatho wokuphosa" -yayikungalungelelanisi phakathi kokuziphatha kwe-alloy, uyilo lokungena, kunye nokulandelelana koxinzelelo lwasemva kokuphoswa. Kulapho lo mzi-mveliso uhambisa khona.
Kutheni i-cobalt-nickel alloys ifuna okungaphezulu nje “kokuphoswa kotyalo-mali”
Uninzi lwababoneleli baphatha i-AMS 5387 okanye i-T800 njengelinye ibakala kwiphepha elithile. Enyanisweni, ezi alloys zicutha i-17% ngaphezu kwe-316 i-stainless ngexesha lokuqiniswa, iphuhlisa i-gradients ye-thermal 3 × i-steeper kumacandelo anodonga oluncinci, kwaye ixhathise i-machining ngokukrakra kangangokuba izixhobo ze-carbide zinxiba i-40% ngokukhawuleza ukuba unyango lwangaphambi kokushisa aluzange lubekwe ngexesha elifanelekileyo. Siyilinganisele le nto-kwizindlu zokwenyani zempompo zepiston ezakhelwe ioyile engaselunxwemeni kunye nenkonzo yerhasi.
I-QINGDAO QIANGSENYUAN ayikhupheli ngaphandle isiqinisekiso sealloyi. Iqela labo lobugcisa lidibanisa iibhetshi zezinto eziluhlaza kunye nabanikezeli abaqinisekisiweyo-ukulandelela ukusabalalisa ubungakanani bengqolowa, i-intermetallic phase dispersion, kunye nomxholo we-oksijini ukuya kwi-15 ppm. Xa umthengi ethumela umbhobho we-T800 ngokhukuliseko lwangaphambi kwexesha emqaleni, siye sawulanda emva kokungahambelani kwemvula ye-niobium carbide kwindawo enye yobushushu. Ulungiso? Ukulungelelanisa isisombululo serempu ye-anneal nge-0.8°C/sec-kunye nokubamba amaxwebhu ngekhilogram nganye eyaphosiweyo.
Eli nqanaba lolawulo lisebenza kuphela ngenxa yabo Umzi-mveliso wokugalela imali we-IMPRO idibanisa amanyathelo enkqubo yezinye isili: ipateni yewax yejiyometri iqinisekisiwe ngokuchasene neendlela zesixhobo ze-CNC *phambi* kokwakhiwa kweqokobhe; imijikelo yonyango lobushushu ilungelelaniswa kunye nezixhobo zokugqibela zomatshini; iiparamitha zokugqiba umphezulu (Ra ≤ 0.4 μm) ziqinisekiswa kusetyenziswa i-optical profilometry-kungekhona nje i-tactile probes-kuba ukuhamba kwe-turbulent kufuna ukuphindaphinda kwe-sub-micron.
Udibaniso oluthe nkqo aluyiyo i-buzzword-lunyamezelo lwe-inshurensi yokupakisha
Abanye abathengisi bacaphula ukuphoswa kuphela, emva koko umatshini wokwenza ikontraka ukuya kwiivenkile ezintathu ezahlukeneyo. Oko kwazisa imposiso eyongezelekayo: ukucutha ukucutheka + ukutshintshwa kwe-machining fixture + thermal distortion = iinxalenye ezilingana neCMM kodwa zibophelela kwindibano. Kwi-QINGDAO QIANGSENYUAN, iqela elifanayo lobunjineli liphethe ikhonkco elipheleleyo-ukusuka kwi-GD & T ukutolika kwifowuni yokuphonononga umzobo ukuya kuvavanyo lokugqibela lokusebenza kwibhentshi ye-hydrostatic.
Silandelele imizimba engama-42 yevalvu yoxinzelelo kwiindlela ezimbini zokuvelisa. Ezo zifakwe ngoomatshini ngaphakathi endlwini zibonise ukuphindaphindwa komgangatho wama-92% kwiindawo ezibalulekileyo zokutywina. Abo banikwe umsebenzi wangaphandle behle baya kuma-68%. Umehluko? I-Fixture-to-fixture-to-fixture transfer errors transferring 0.018 mm-eyanele ukuthomalalisa i-bubble-tight shutoff kwi-bar ye-250.
- CNC machining: i-5-axis contouring ngaxeshanye kwiipaseji ezintsonkothileyo zangaphakathi kwiziseko zempompo
- Unyango lobushushu: I-vacuum annealing kunye nemephu yexesha langempela le-thermocouple ngaphakathi komthwalo ngamnye
- Ukugqiba: Electropolishing for corrosion resistance * kunye * micro-smoothness-ingqinwe yi-SEM imaging
Akukho nyathelo linikezelwayo ngaphandle kokulandelelwa okubhaliweyo: amanani eqashiso, ii-ID zabasebenzisi, iilog zokulinganisa koomatshini, kunye neengxelo zeCMM ezigcinwe ngokwemigangatho ye-AS9102-nangee-odolo ezingezizo ezomoya. Ngenxa yokuba xa i-winch centre shaft roller ingaphumeleli ukunyuswa kwi-excavator yemigodi, "silandele inkqubo" akwanelanga. Ufuna ubungqina bokuba *yintoni* inkqubo—kwaye kanye ukuba isebenze njani.
Ukuhanjiswa kwelizwe lokwenyani kuthetha ukuphendula ngobunjineli-hayi nje imihla yekhalenda
"Ukuhanjiswa ngexesha" akuthethi nto ukuba ukuthunyelwa kokuqala kufika kunye nentambo engachanekanga kwiplagi ye-cobalt alloy. I-QINGDAO QIANGSENYUAN yakha ukomelela kwishedyuli kubunjineli-kungekhona izinto. Abaphathi beprojekthi yabo abalandeli nje ixesha lokukhokela; babonisa imingcipheko yokwenziwa kwezixhobo *phambi kokuba* kuqalise izixhobo.
Kunyaka ophelileyo, umxhasi waseYurophu ungenise i-GD&T ehlaziyiweyo yebhloko ye-hydraulic manifold. Iqela lethu libone ukuba ukunyamezela isikhundla esichaziweyo (± 0.025 mm) kwi-datum C kuya kufuna ukugaya emva kokuphosa-ukongeza i-$ 1,200 / iyunithi kunye nokulibaziseka kweeveki ze-3. Endaweni yoko, bacebise ukuguqula ushicilelo olungundoqo ukuguqula i-datum kwindawo yomatshini, ukuphumeza ukulungelelaniswa komsebenzi ofanayo kwi-40% yeendleko eziphantsi. Umxhasi uvunywe kwiiyure ezingama-48.
Oku kwenzeka ngenxa yokuba iinjineli zabo zithetha zombini isiseko kunye ne-fluid dynamics. Bayazi ukuba kutheni i-0.1 mm ye-offset kwi-engile yokukhupha i-nozzle itshintsha ukusebenza kwepateni yokutshiza nge-11%. Bavavanye i-flow coefficients kwi-17 ye-cobalt alloy geometries-hayi ukusuka ekufaniseni kuphela, kodwa ngeebhentshi ezihambayo ezilinganisiweyo eziqhuba ulwelo olusebenzayo.
Ukuba ukhangela iindawo zetsimbi ezichanekileyo apho ukusebenza kuxhomekeke kwingqibelelo ye-microstructure, kungekhona nje imilinganiselo ye-macro, ukhetho alukho phakathi kwabathengisi-kuphakathi kweengcinga kunye nobungqina. An Umzi-mveliso wokugalela imali we-IMPRO ayithembisi imfezeko. Inika iziphumo ezinokulandeleka, eziphindaphindwayo, eziqinisekisiweyo ezisebenzayo-icandelo elinye elibalulekileyo ngexesha.
