Lapho onjiniyela bedinga a imboni yokukhipha i-wax elahlekile eletha ukunemba okuphindaphindwayo kumabhobho e-cobalt alloy, izindlu zephampu ze-AMS 5387, noma ama-winch shafts we-T800—ayithumeli nje imidwebo. Bahlola isiyalo sensimbi somphakeli, ukulawulwa kobukhulu, kanye nokuzimisela ukumaka izingxabano ze-GD&T ngaphambi kokuthi kuqale ukusebenza.
Sibone ukwehluleka okuthathu okujwayelekile ebudlelwaneni bokusakaza bokutshalwa kwezimali obunembayo: okokuqala, ukwakheka okusanhlamvu okungahambisani kuwo wonke amaqoqo e-cobalt-nickel afakwe ukushisa; okwesibili, izilinganiso eziqinisekisiwe ze-CMM ezidlula ukuhlolwa kodwa zihluleke ukuhlolwa kwengcindezi yokusebenza ngenxa yengcindezi esele; okwesithathu, imininingwane yokuqedwa komphezulu yahlangana ephepheni—kodwa i-micro-porosity ibukela phansi ukumelana nokugqwala kusevisi kawoyela negesi. Lawa akuwona amaphutha okukhiqiza. Bayizikhala zenqubo.
Kungani Ukuhlanganiswa Okuqondile Kubaluleke Kakhulu KuneSitifiketi Sodwa
Isitifiketi sikungenisa emnyango. Ukulandelelwa kwezinto ezilawulwayo kukugcina ekukhiqizeni. Kwa-QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD., njalo ukusakaza kwe-AMS 5387 kuqala ngamaphepha e-T800 alloy aqinisekiswe ngomshini—aqinisekiswa ngamakhemikhali lapho athola, ahlukaniswa ngenombolo yokushisa, futhi alandelelwa ngokuhlaziywa kokuncibilika, ukwakhiwa kwamagobolondo, i-dewax, ukutubeka, ukuthululwa, nokwelashwa kokushisa kwangemuva kokusakazwa. Alikho iqoqo elihambayo ngaphandle kokuqinisekiswa kwe-optical emission spectroscopy (OES) nokugawulwa komlando oshisayo.
Lokhu akukhona ukuthobela kwethiyori. Kwelinye i-oda lakamuva laseNyakatho Melika lezindlu zesilinda sephampu ye-piston, ithimba lethu libambe ukuphambuka kwekhabhoni okungu-0.012% esitokisini se-cobalt alloy esihlinzekwe ngumhlinzeki ngesikhathi sokuhlolwa okungenayo. Simise kancane ukusakaza, sakhipha amanye amabhilidi, saphinde sasebenzisa ukulingisa okushisayo—sigwema umjikelezo we-scrap wamaviki angu-14. Lokho akukhona ukunciphisa ubungozi. Lokho kuwukuziphendulela okugxilile kwe-metallurgical.
Amandla aqondile asho ukuthi ukwenza imishini akuyona into ecatshangelwayo. I-cobalt alloy nozzle ayiphonswa bese "ithunyelwa ku-CNC." Isakazwa ngesabelo somshini esingu-0.3 mm, inomshini oqinile ngenkathi isafudumele ukuze ikhulule ingcindezi, indala, yenziwe ngomshini wokuphotha amagiya angu-5 e-DMG MORI aqhutshwa ngophenyo—futhi ihlolwe kusetshenziswa ama-Zeiss CONTURA G2 CMM alinganiswa nsuku zonke ngokumelene nezingcweti ezilandelekayo ze-NIST. Ukuzinza kwe-Dimensional akulinganiswa ekuhlolweni kokugcina. Ifakwe ohlelweni lokusebenza.
Lapho Izimboni Ezijwayelekile Zokusakaza Zifinyelela Imikhawulo yazo—nokuthi Ozakwethu Abaneqiniso Baphendula Kanjani
Abanye bangase baphikise ngokuthi ukuphonsa kwesihlabathi kwanele izingxenye zensimbi ezisindayo njengezisekelo zephampu. Kodwa uma ukujiya kodonga kushintsha kusuka ku-25 mm kuya ku-120 mm ekubunjweni okukodwa—futhi ubuqotho bokusebenza budinga ≤0.05 mm ukucaba kokucaba ngaphezu kuka-600 mm—ukunemba kwesikhunta segobolondo kuba yinto engaxoxiswana nayo. Ukukhishwa kwe-wax okulahlekile "akungcono." Iyona ndlela kuphela elawula ukuthambekela kokuqina ngokuqinile ngokwanele ukuze kuvinjwe ukushwabana komugqa omaphakathi ezigabeni eziwugqinsi kuyilapho ubambe ukubekezelela okungu-±0.15 mm kumaflange amancane.
Ngokuvamile sibona amakhasimende eshintsha kusuka esihlabathini kuya ekutshalweni kwezimali kwephrojekthi emaphakathi-hhayi okobuhle, kodwa ngenxa yokuthi imizimba yawo yamavalvu e-hydraulic yayilokhu ihluleka ukuhlolwa kokuqhuma ku-4,200 psi. Imbangela? I-Micro-shrinkage porosity ehambisana namashaneli okupholisa angaphakathi. Ukushintshela ku-wax elahlekile enesango elilawulwayo kanye nokuqiniswa kokuqondisa kususe iphutha. Isisindo sengxenye sikhuphuke ngo-3.7%. Izinga lokuhluleka kwenkundla lehlile lisuka ku-12% laya kuziro.
Lolo shintsho lwaludinga okungaphezu kwemishini. Ifune onjiniyela abakhipha izinto abakhuluma i-GD&T kahle, ochwepheshe bemishini abaqonda ukuthi izinga lokuqina kwe-cobalt likuthinta kanjani ukulandelana kwendlela yamathuluzi, kanye nochwepheshe be-QA abaqeqeshelwe ukuhlobanisa imiphumela yokuskena kwe-ultrasonic namabha okuhlola aqinile athululwe ku-ladle efanayo.
Okuphumayo Komhlaba Wangempela: Yeka Ifekthri Yokusakaza Ngengcina Elahlekile Yangempela Elethwayo
Lokhu kuhumushelani phansi esitolo? Imiphumela emine ebonakalayo:
- Ijiyomethri esebenzayo, hhayi nje ubukhulu begama-indlu ye-valve yokucindezela eyenziwe ukuze iphrinte, kodwa futhi yaqinisekiswa ukuqondisa kwendlela yokuhamba ngaphansi kokunwetshwa okushisayo okufanisiwe
- Ukuvumelana kwe-batch-to-batch metallurgical-Izingxenye ze-AMS 5387 zihlolwe i-ASTM E112 ngayinye ngosayizi wokusanhlamvu, i-ASTM E140 yokuqina, kanye ne-ASTM E8 ukuze kube namandla aqinile-konke kubhalwe ngenombolo ngayinye yokushisa
- Ubuqotho bobuso bufaniswe nohlelo lokusebenza—U-Ra 0.4 µm ebusweni obuvaliwe, u-Ra 3.2 µm endaweni ekhwezayo, nengcindezi eyinsalela ecindezelwe ngokudutshulwa ezindaweni zokukhathala zomjikelezo omkhulu
- Azikho izimanga ekuhlolweni kwe-athikili yokuqala-Iphakheji egcwele ye-FAI ihlanganisa izitifiketi zezinto ezibonakalayo, izingodo zokuphatha ukushisa, imibiko ye-CMM, idatha yokuqeda phezulu, namarekhodi okuhlola asebenzayo-konke kuthunyelwe kusengaphambili ukuze kubuyekezwe amakhasimende
Kungakho amaqembu onjiniyela e-Europe ecacisa i-QINGDAO QIANGSENYUAN yemihlangano yephampu yasolwandle, futhi kungani ama-OEM aseNingizimu mpumalanga ye-Asia ewathemba ngamarola angewona ajwayelekile esikhungo se-T800 eshaft amawini ezimayini. Akukhona mayelana nokucaphuna okuphansi kakhulu. Kumayelana nokususa izihibe zokuphinda zakhiwe ngaphambi kokuthi kwakhiwe iphethini yokuqala.
Ukukhetha Imboni Yakho Yokusakaza Ye-Wax Elahlekile: Bheka Ngalé Kwencwajana
Buza le mibuzo emithathu ngaphambi kokusayina inkontileka:
- Ungakwazi ukungibonisa imibiko emithathu yokugcina ye-OES yezinto ze-AMS 5387 ozicubungulile—futhi uqinisekise ukuthi ibuyekezwe i-metallurgist yasendlini yakho ngaphambi kokusakaza?
- Ingabe opharetha bakho be-CMM bayalinganisa ama-probes ngokumelene nama-artifact ayinhloko ngaphambi kweshifu ngayinye—noma kanye kuphela ngeviki?
- Uma sithumela umdwebo onamazwi e-GD&T abhekisela ku-ASME Y14.5–2018, ingabe onjiniyela bakho baphawula izinkinga zokwenziwa emahoreni angu-72—noma balinde kuze kufike i-prototype?
Uma izimpendulo zingenakho ukucacisa—noma zincike kokuthi “silandela i-ISO”—qhubeka ubheka. Ukunemba kwangempela kuqala lapho imibhalo iphela khona futhi ukwahlulela komuntu kuqala. Ezicelweni ezifunayo, leso sahlulelo kufanele sisekelwe amalogi omlilo, ukuphuma kwe-spectrometer, namarekhodi okulinganisa uphenyo—hhayi nje izitifiketi.
Ikusasa lokusakazwa kwe-alloy ephezulu lilele ezinqubweni ezihlanganisiwe: ukwakheka kwe-investment cast eduze kwenetha kuqedwe ngokugaya ngesivinini esikhulu, bese kugqokwa nge-laser nokumbozwana okungagugi. I-QINGDAO QIANGSENYUAN TECHNOLOGY isivele yenza i-prototyping yalokhu kumafutha esizukulwane esilandelayo neziqu zevalvu yegesi. Kodwa impumelelo yanamuhla isancike ezintweni eziyisisekelo—ukulandeleka kwezinto ezibonakalayo, isiyalo sobukhulu, kanye nesibindi sokuthi “lo mklamo uzoqhekeka” ngaphambi kokuba kuphole iphethini yokuqala ye-wax.
Yilokho okuchaza iqiniso imboni yokukhipha i-wax elahlekile.
