Lapho onjiniyela becacisa ukufakwa kwe-investimenti yensimbi engagqwali kumavalvu ka-hydraulic abalulekile kumishini noma izindlu zephampu ezinomfutho ophezulu, abagcini nje ngokukhetha inqubo—babheja ngokuphindaphinda kwe-dimensional, ubuqotho be-microstructural, kanye ne-zero compromic ekumelaneni nokugqwala. Kungakho ama-OEM omhlaba ehlala ebuyela ku-a insimbi engagqwali utshalomali casting factory ephatha konke ukuthululwa njengomcimbi onembayo: QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD.
Kungani I-Investment Casting—Hhayi Isihlabathi Noma Ifa—Iwina Ngezingxenye Zokunemba Kwensimbi Engagqwali
Ama-alloys ensimbi engagqwali afana ne-SS316, 17-4PH, kanye namabanga ayiduplex amelana nokugqokwa komshini—kodwa futhi amelana nokubunjwa okungenakuguqulwa. Ukubunjwa kwesihlabathi kwethula ubulukhuni obungaphezulu kanye nesakhiwo sokusanhlamvu esingaguquki. I-Die casting ihluleka ngezinsimbi ezingenasici eziphezulu zokuncibilika. Ukutshala imali kuvala igebe: ukunemba kwephethini ye-wax idlulisela ngokuqondile ku-geometry yokugcina, okuvumela ukubekezelelwa okungu-±0.05 mm ezicini ezincane njengo-0.8 mm ubukhulu bodonga. Sibone amakhasimende eshintsha esuka kumabhilidi enziwe ngomshini we-CNC aye ekutshalweni kwezimali—futhi anciphisa ingxenye yesisindo ngo-37%, isikhathi somshini ngo-62%, kanye nemfucuza yezinto ezibonakalayo ngaphezu kuka-80%. Ukuhwebelana? Ukulawula okuqinile ekwakhiweni kwamagobolondo, amanani erempu aphuma ewaxing, nomoya wesithando somlilo. Akuzona zonke izitolo ezingakwazi ukuyibamba.
Amakhono Amane Ahlukanisa Imboni Yokusakaza Yensimbi Engenasici Yangempela Kwamanye
Kwa-QINGDAO QIANGSENYUAN, "ukutshala imali" akuwona umugqa owodwa eshidini lamakhono. Kungukugeleza komsebenzi okuhlanganisiwe okuqondile lapho insimbi, ithuluzi, nokuhlola kukhuluma nsuku zonke:
- Ukuphatha i-alloy eqinisekisiwe: Akukho ukushisa okukhethekile. Yonke inqwaba yensimbi engagqwali ithwala ama-MTR agcwele (Imibiko Yokuhlolwa Komshini) elandeleka kusitifiketi se-EN 10204 3.1—futhi sihlola okuqukethwe kwekhabhoni, i-chromium, ne-nitrogen endlini ngaphambi kokuqala kokwakhiwa kwamagobolondo.
- Isiyalo se-Hybrid casting + machining: Izindlu zesilinda sephampu yepiston zifika zivela esithandweni zinesabelo sesitoko esingu-0.3 mm—hhayi u-2 mm. Umshini wethu wamaseli we-CNC wamaseli angu-5 umshini wokuvala okubalulekile kanye nezintambo zembobo *ngokusetha okukodwa*, asusa amaphutha okulungisa awonakalisa amazinga okuphasa okucindezelayo.
- I-AMS 5387 & T800 yokulingisa i-cobalt-grade ngokushelelayo: Lezi akuzona izinto "ezisebenzayo" lapha. Sisakaza imibhobho ye-AMS 5387 enamashaneli okupholisa angaphakathi ngaphansi kokuthululwa kwegobolondo elisizwa ngevacuum—futhi ngokuvamile sibamba ama-callout e-GD&T njengokubekezelela indawo Ø0.02 mm kuzici ezingu-12-mm-diameter.
- Ukulandelelwa kwenqubo egcwele kuze kufike kunombolo yokushisa: Uma ikhasimende lihlaba umkhosi okudidayo ku-Loti #QS-2408-77B, sidonsa ilogu yomjovo we-wax yasekuqaleni, umbiko we-X-ray yegobolondo, ukuphrinta kokuhlaziya okuncibilikayo, kanye nedatha yokuskena ye-CMM—konke phakathi nemizuzu engu-90.
Lokho Amakhasimende Akubuza Empeleni—Futhi Abangavamile Ukukusho Kakhulu
"Ungakwazi ukuphonsa lo mzimba we-valve ongu-316L onodonga oluwu-2.5 mm kanye nerediya yangaphakathi ngaphansi kuka-1.2 mm?" Yebo-kodwa kuphela uma i-engeli yokusalungiswa kwephethini ye-wax idlula u-0.8 ° futhi igobolondo lixoshwa ku-1020 ° C amahora angu-3, hhayi 2. Lokho kuyiqiniso elingashiwongo: impumelelo yokufaka utshalomali yensimbi engagqwali ihlala kumaphrofayili okushisa, i-binder chemistry, nokwahlulela komsebenzisi-hhayi nje amafayela e-CAD.
Silahlekelwe isibalo sokuthi mangaki ama-RFQ afikayo “nokuqedwa kwendawo esakazwayo engu-Ra ≤ 3.2 µm.” Lokho kuyafezeka—kodwa kuphela ngama-ceramic slurries alungiselwe ibala, hhayi i-aluminium. Futhi yebo, siyakwenza. Kodwa siphinde sitshele amaklayenti kusenesikhathi: ukuzuza i-Ra ≤ 1.6 µm kudinga ukuqhuma kwengilazi yobuhlalu *kanye* nokuqedwa kokudlidliza—futhi kwengeza u-18% esikhathini sokuhola. Ukubonisa ngale akuyona inqubomgomo lapha. Iphrothokholi.
Omunye ovame ukubuza: "Ingabe ungashisela i-flange ngemuva kokuphonsa?" Ngobuchwepheshe yebo. Cishe cha—kuzingxenye ezingu-17-4PH ezihloselwe uwoyela ogwini kanye nesevisi yegesi. Izindawo ezithinteke ngokushisela zicekela phansi i-microstructure eqinile. Impendulo yethu? Faka i-flange ebalulekile. Yebo, izindleko zamathuluzi ziyakhuphuka. Kodwa ukwehluleka kwenkambu kwehlela kuqanda. Lokho onjiniyela be-ROI abalinganisa ngempela.
Lapho Ukunemba Kuhlangana Khona Ubambiswano—Ngaphandle Kwesitezi Se-Foundry
Imboni yokukhipha utshalomali yensimbi engagqwali izuza ukwethenjwa uma isebenza njengesandiso sethimba lakho lonjiniyela—hhayi umthengisi olinde ama-PO. Ku-QINGDAO QIANGSENYUAN, lokho kusho:
- Isibuyekezo samahhala sokwenziwa komdwebo kuwo wonke umdwebo—ngokuqinisekisa kwe-callout ye-GD&T nezinye iziphakamiso zenqubo (isb., “Le Ø14.2±0.015 mm bore isakazwa ngomshini kangcono kunokuzama ukuyifaka phakathi”);
- Ukulandelana kwe-Prototype-kuqala: ukulingisa okusebenzayo okuthathu okuthunyelwe ngezinsuku eziyi-14, nemibiko egcwele ye-CMM nezingxenye eziphambanayo zensimbi;
- Azikho izimanga ekulethweni: ibhodi lethu lokukhiqiza elithambile lilandelela ingxenye ngayinye kusukela kumjovo we-wax nge-NDT yokugcina—futhi izibuyekezo zabiwa masonto onke, hhayi nje lapho kuhanjiswa.
Asijahi ivolumu. Sixazululela izindlela zokwehluleka: ukuguguleka kwezixhumi zephampu enodaka, ukukhathala okushisayo emizimbeni yamavalvu e-steam, ukugegetheka kwamarola e-winch centre-shaft. Lokho kugxila kusivumela ukuthi siphushe imingcele—njengokuphonsa umzimba we-valve engu-316L enezindonga ezingenayo i-porosity zangaphakathi ezingu-100% ku-0.5 mm ukujiya. Kwenziwe. Kabili.
Igama Lokugcina: Ukunemba Akudlalwa—Kuyakhiwe, Kuqinisekisiwe, Futhi Kulethiwe
Uma uhlelo lwakho lokusebenza ludinga ukufakwa kwe-investimenti yensimbi engagqwali okubambelela ngokuqinile ku-spec—ngaphansi kwengcindezi, ngaphansi komthwalo, ngaphansi kokuhlolwa—bese kuba nobudlelwano nefekthri eyakhelwe izinto eziyinkimbinkimbi ngaphezu kokuba seduze noma intengo. QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD. isebenza njenge-a insimbi engagqwali utshalomali casting factory lapho zonke izinyathelo zenqubo ziphendula umbuzo owodwa: "Kudingani ukwethembeka ekusebenzeni-hhayi lokho okulula ukukucaphuna?"
Waba yini umphumela? Izingxenye ezidlula ukuhlolwa kwe-hydrostatic ku-1.5 × ingcindezi elinganiselwe. Izingxenye ezisinda emijikelezweni engu-20,000+ kumasekhethi abrasive hydraulic. Futhi ubudlelwano obuthatha iminyaka engu-7+—hhayi nje umjikelezo we-oda owodwa. Ngoba ekusebenzeni kwensimbi okuphakeme kakhulu, ukunemba akuyona into yokuzikhethela. Akuxoxiswana ngakho.
