Lapho onjiniyela bayacacisa Izingxenye ze-Incoloy alloy, abagcini nje ngokukhetha ukwaziswa—bazibophezela ekuzinzeni kobukhulu ngaphansi kokushaqeka okushisayo, ukumelana nokugqwala endaweni yegesi emuncu, nempilo yokukhathala ezimisweni zomjikelezo ophezulu we-hydraulic. Yingakho ukhetha okulungile I-Incoloy alloy parts factory ayimayelana nenani eliphansi kakhulu noma ikhwothi eshesha kakhulu. Imayelana nokulawulwa kwe-metallurgical okuqinisekisiwe, ukwenziwa kabusha okuphindaphindwayo kwama-alloys e-cobalt-nickel e-AMS 5387-grade, kanye nokubekezelela iqanda lokungavumelani kwe-microstructural kuwo wonke amaqoqo.
Izinselelo zomhlaba wangempela zidinga isiyalo senqubo yangempela-hhayi nje isitifiketi se-alloy
Sibone amaphrojekthi amaningi emiswa lapho abahlinzeki bephasa izitifiketi zezinto ezibonakalayo kodwa behluleka ubuqotho bendawo ethinteke ukushisa ngemva kokusikwa kwe-EDM. Noma lapho ukubekezelelwa kwe-“as-cast” kukhukhuleka ukudlula ±0.3 mm kusilinda sephampu yepiston engu-320-mm-okubangela ukuvuza kophawu ku-4,000 psi. Kwa-QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD., yonke ingxenye ye-Incoloy iqala nge-T800 eqinisekisiwe yokugaya noma i-AMS 5387 billet. Kodwa isitifiketi sisodwa asiqinisekisi ukusebenza. Siqinisekisa ukugeleza kokusanhlamvu ngaphambi komshini onzima. Siqapha izinga lokushisa le-interpass ngesikhathi sokugaya ama-axis amaningi emizimba yama-valve ukuvimbela ukuzwela kwendawo. Futhi siqinisekisa ubulukhuni bokugcina *ngemuva* kokudambisa ingcindezi—hhayi ngaphambili.
Lokhu akulona ithiyori. Ngonyaka odlule, i-OEM yesisetshenziswa senkundla kawoyela yaseYurophu yenqaba inkatho ye-prototype emithathu komunye umphakeli ngenxa yokufundwa okungahambisani kwe-delta-ferrite kumaflange ashiselwe i-Incoloy 825. Ithimba lethu lenze izifaniso zomjikelezo oshisayo ohambisanayo, amapharamitha okushisa alungisiwe, futhi laletha imvume yokudlula yokuqala ku-Lot #4—ngama-MTR agcwele, imibiko ye-CMM, nama-macrographs ahlukaniswe ngezigaba afakwe kungobo yomlando ngeSigaba IX se-ASME BPVC ngasinye.
Ukuhlanganiswa okuqondile kusho ukungabi khona kwesandla—futhi akukho okuguquguqukayo okufihliwe
Amafekthri amaningi “ezingxenye ze-Incoloy alloy” asakaza ngaphandle, umshini ngaphandle, noma ukuqedwa kwenkontileka engaphansi. Lokho kudala izikhala: i-porosity yokuphonsa ephuthelwe ukuhlola okubonakalayo, ingcindezi eyinsalela eyenziwe ngomshini engadalulwanga ngaphambi kokugaya okokugcina, ukuqedwa okuphezulu okubukeka kushelelezi kodwa okuhluleka ukuhlolwa kwesifutho sikasawoti ngemva kwamahora angu-120. I-QINGDAO QIANGSENYUAN ingumnikazi wochungechunge olugcwele—kusuka ekutshalweni kwezimali kwezisekelo zephampu eziyinkimbinkimbi ukuya ekuhlanganiseni kwe-CNC yama-axis amahlanu wamabhomu engxubevange ye-cobalt, bese kuya ekuqedeni okulawulwayo kwe-atmosphere kanye nokupholishwa ngogesi.
Asikuphathi ukulingisa kanye nokwenza imishini njengeminyango ehlukene. Onjiniyela bethu abasunguli bahlala nabahleli bezinhlelo be-CNC ngesikhathi sokubuyekezwa kwe-DFMA. Lapho ikhasimende lithumela i-GD&T ye-Incoloy 625 winch center shaft roller, ithimba lethu lihlaba umkhosi lapho ama-engeli asalungiswa e-sand-cast engqubuzana nezindawo ezithwalayo ezisebenzayo—futhi liphakamisa isisombululo esiyingxubevange: ukusakaza kwe-neet-net-shape + precision ID/OD turning + ukuqina kwezindawo ezisizwa nge-laser ezindaweni ezigugile. Lokho kunciphisa isikhathi sokuhola ngo-37% futhi kuthuthukisa ingcindezi yensalela ecindezelwayo engaphezulu ngo-210 MPa uma kuqhathaniswa nokuqina kokufakwa kwemishini kwangemuva komshini kuphela.
Ikhwalithi ayihloliwe—yakhiwe ngaphakathi, isendlalelo ngesendlalelo
Indawo yethu ethobela i-ISO isebenzisa izindawo zokuhlola ezintathu okungaxoxiswana ngazo kuyo yonke ingxenye ye-Incoloy:
- Ukuqinisekiswa kwezinto: Ukuhlaziywa kwe-Spectrometric + ukuskena kwe-PMI emigoqweni engenayo, kanye nokuhlolwa kwe-ultrasonic kokungaqhubeki kwe-subsurface
- Ukuqinisekiswa okungaphakathi kwenqubo: Isilinganiso se-CMM ngemva kokusebenza ngakunye okubalulekile—hhayi nje ukuhlola kokugcina—kanye ne-optical profilometry ezindaweni zokuvala
- Ukukhishwa okusebenzayo: Ukuhlolwa kwengcindezi ye-Hydrostatic ku-1.5× design ingcindezi, kulandelwa ukuhlolwa kokuvuza kwe-helium ku-≤1×10⁻⁹ mbar·L/s kuma-valve assemblies
Akukho okuhlukile. Akukho "ukuchezuka okugunyazwe ikhasimende." Uma ipulaki ye-cobalt alloy yehluleka ukuba rough surface Ra ≤ 0.4 µm esihlalweni sayo esikhonkolo, iyasetshenzwa kabusha—hhayi ukukhishwa ngokuyekelela. Ukulandeleka kubhakwa kokuthi: ingxenye ngayinye iphethe ikhodi ye-QR exhunywe kwikhevu yokwelapha ukushisa okuqondene nenqwaba, ilogu yendlela yamathuluzi womshini, kanye nombiko wokuhlola. Lokho kubalulekile lapho ukuhlanganiswa kwephampu yakho kwehluleka ukuhlolwa kokudlidliza ngo-12,000 rpm—futhi udinga ukuhlukanisa ukuthi ingabe imbangela bekuwukukhipha ukuncipha noma ukuhlanekezela kwangemva komshini.
Yini ngempela eshukumisa inaliti yamaqembu okuthengwa kwempahla omhlaba
Abathengi basibuza imibuzo emithathu ngaphezu kwanoma yimuphi omunye:
- "Ungakwazi ukubamba u-±0.05 mm emzimbeni we-valve engu-280-mm-ubude we-Incoloy 800-ngaphandle kwe-warpage ngemva kokukhululeka kwengcindezi?" Yebo. Sisebenzisa idizayini yokuhlanekezela okuphansi, imijikelezo yokudonsa epholile, kanye nemephu ye-CMM yokwelapha ngemva kokushisa ukuze siqinisekise ukuhlala okuphansi ngaphakathi kokufunda kwenkomba okuphelele kuka-0.08 mm.
- "Ingabe uyakweseka ukwenziwa kwe-prototyping yeqoqwana elincane ngemibhalo egcwele-ngisho namajiyometri angajwayelekile njengama-asymmetric AMS 5387 nozzles?" Yebo. I-oda lethu elincane lezingxenye ze-Icoloy zangokwezifiso iyunithi eyodwa esebenzayo—nama-MTR agcwele, imibiko yobukhulu, namakhuphoni okuhlola okubalulekile afakiwe.
- “Uzisingatha kanjani izinguquko eziphuthumayo zamaphakathi nokukhiqiza—njengokushintsha usuka ku-Incoloy 600 uye ku-625 ngenxa yedatha yokuchayeka kwe-chloride?” Siqinisekisa kabusha izindlela zokuhamba kwezinto phakathi kwamahora angama-48. Hhayi "buyekeza imigqa yesikhathi." Hhayi "ukuhlola ukuba nokwenzeka." Sisebenzisa amasampula amasha aqinile, sibuyekeza izikhathi zokucwiliswa kokwelashwa kokushisa, futhi sikhiphe izinhlelo zokuhlola ezibuyekeziwe—ngaphambi kokusika insimbi.
Lokho kusabela kuvela kubunikazi bonjiniyela—hhayi izithembiso zokuthengisa. Yonke iphrojekthi inomholi ozinikele wezobuchwepheshe okhuluma kahle i-GD&T, oqonda izidingo ze-microstructure ye-ASTM A494 Grade CW6MC, futhi asayine ukukhishwa kokugcina.
Uma isicelo sakho esilandelayo se-Icoloy sifuna okungaphezu kokuthotshelwa kwe-alloy—uma sidinga i-microstructure ebikezelwayo, ukuziphatha okunobukhulu obuqinisekisiwe ngaphansi komthwalo, kanye nokungaqondakali kahle ekuziphenduleleni kwenqubo—khona-ke ukukhetha akukho phakathi kwabathengisi. Kuphakathi kokwamukela ingozi nokuyiqeda. QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD. yakhela ukwethembeka okubalulekile komgomo, hhayi nje ukuthobela imininingwane. Ngoba ezindaweni ezinomfutho ophezulu, izinga lokushisa eliphezulu, nemiphumela ephezulu, alikho ithuba lesibili lokuthola i-metallurgy ngendlela efanele.
