Lapho onjiniyela becacisa a imboni yokukhipha imali ye-wax elahlekile ezingxenyeni zensimbi ezinobuqotho obuphezulu, azithengi nje ukulingisa—zivikela ukuphindaphinda kobukhulu, ukulawulwa kwesakhiwo esincane, nokuthembeka kokusebenza ngaphansi kwezimo zesevisi ezimbi kakhulu. Sibone amaphrojekthi amaningi ebambezelekile—hhayi ngamaphutha edizayini, kodwa ngamakhono okusakaza angafani. Izindlu zamavalvu ezidlula ukuhlolwa kwe-CMM kuzinga lokushisa legumbi zingasonteka ngemva kokwelashwa kokushisa uma i-Foundry ingenakho ukuqinisekiswa kwenqubo ehlanganisiwe yokushisa. Umbhobho we-cobalt alloy ungase uhlangabezane nokucaciswa kwamakhemikhali ephepheni kodwa wehluleke ukumelana nokuguguleka kwensizakalo uma ukwakheka kokusanhlamvu bekunganakiwe kuwo wonke amanzi. Yingakho ukunemba kungachazwa ngokubekezelelana kuphela-kwakhelwe ekuhambeni komsebenzi.
Kungani Ukulahleka Kwezimali Zokutshala Kwe-Wax Kudinga Ukuhlanganiswa Okuqondile-Hhayi I-Foundry Nje
Ukutshala imali kudlula lapho ukufakwa kwesihlabathi kungeke kwenzeke khona: izindonga ezincane, amaphaseji angaphakathi ayinkimbinkimbi, ama-callouts aqinile we-GD&T, kanye nokuqedwa kahle kwendawo (Ra ≤ 1.6 µm). Kodwa lezo zinzuzo ziyawa ngaphandle kokuhlangana okuqinile phakathi kokwenziwa kwephethini, ukwakha amagobolondo, ukucwiliswa kwe-waxing, ukudubula, ukuthela, kanye nomshini wokuphonswa kwangemuva. Esikhungweni sethu e-Qingdao, asikhiphi noma yisiphi salezi zinyathelo. Silawula iketango eligcwele—kusuka kumathuluzi e-silicone amaphethini we-wax kuya ekomisweni kwegobolondo le-ceramic elisizwa nge-vacuum, kusukela kumahhavini we-dewax wezinga lokushisa elilawulwayo ukuya ekuthululweni kwegesi ye-inert ye-AMS 5387 cobalt alloy ku-1,480°C. Kungani lokho kubalulekile? Ngoba izinsalela ze-wax ezisele zibangela ukuqhekeka kwegobolondo. Ukomiswa kwegobolondo elingalingani kumema i-porosity. Ukushaqeka okushisayo ngesikhathi sokukhishwa kwe-waxing kudala ama-microfractures angabonakali ku-X-ray kodwa abulale ngaphansi kwengcindezi yomjikelezo. Silinganise ukuncishiswa okungafika ku-22% emvuzweni yephasi yokuqala lapho ubuqotho begobolondo bungaqinisekiswanga nge-ASTM F2897 ngayinye.
Lapho Ubuchwepheshe Bezinto Ezibalulekile Buhlukanisa Abathengisi Kozakwethu
Izisekelo eziningi zenza insimbi engagqwali noma i-ductile iron. Bambalwa abaphatha ama-alloys asekelwe ku-cobalt e-T800—noma benza kanjalo ngaphandle kokudela ubuhlakani. Sesisebenzise ukushisa okungaphezulu kwe-1,400 kwe-AMS 5387 kusukela ngo-2019, ngakunye kuqinisekiswe nge-OES spectroscopy kanye namalogi okwelapha ukushisa alandelekayo. Amakhasimende avame ukubuza: “Ingabe ungakwazi ukubamba ±0.025 mm kusilinda sephampu yepiston engu-320 mm?” Yebo—kodwa kuphela ngoba sisebenzisa *emva* kokudambisa ingcindezi nangaphambi kokuguga kokugcina. Uma siyiphonsa, siyiphathe ngokushisa, bese silinda amahora angu-72 ngaphambi komshini, izingcindezi ezisele zihlanekezela isibhobo. Asiseqi leso sinyathelo. Siphinde futhi sigweme izinqamuleli ezivamile: akukho okushintshiwe “okujwayelekile” kwe-cobalt alloy, azikho izinsimbi zokugcwalisa ezingacacisiwe zokulungiswa kokushisela, akukho misebenzi yesibili engabhaliwe. Lonke ipulaki ye-cobalt alloy, yonke ingxenye yephampu engajwayelekile, iphethe izitifiketi zempahla egcwele, imibiko yokuhlolwa okuqinile, kanye nemephu yokuqina kuzo zonke izindawo ezibucayi.
Isiyalo Senqubo Yomhlaba Wangempela—Hhayi Izitifiketi Kuphela
I-ISO 9001 iyisiteki setafula. Okubalulekile ukuthi ukuqina kuhumusheka kanjani engxenyeni yakho. Iphrothokholi yethu yokuhlola iqala ngokuqinisekiswa kwe-billet okungenayo—hhayi nje izitifiketi zokugaya, kodwa ukuhlolwa kwe-ultrasonic kokungaqhubeki kobuso obungaphansi komhlaba. Ngesikhathi sokuphonsa, ama-thermocouples aqapha ukushisa kwesikhunta kanye nezinga lokushisa lensimbi ngesikhathi sangempela. Ngemuva kokunyakaziswa, konke ukulingisa kuhlolwa ukungena kukadayi (ASTM E165) kanye ne-radiography (ASTM E94) ngaphambi komshini onzima. Ukuhlola kokugcina kuhlanganisa ukuskena kwe-CMM yazo zonke izici ze-GD&T, ukukalwa kokubona kwendawo yokuvala, nokuhlola okusebenzayo—njengokuhlola ingcindezi ye-hydrostatic ku-1.5× ingcindezi yokusebenza yemizimba yamavalvu. I-OEM eyodwa ye-hydraulic yaseYurophu yehlise ukwehluleka kwenkundla ngo-68% ngemva kokushintshela ezindlini zethu zamasilinda—hhayi ngoba ukubekezelelana kuqinisiwe, kodwa ngenxa yokuthi senze imephu futhi salawula ama-vectors ahlanekezela emijikelezweni eshisayo engu-12.
Ukukhetha Imboni Yokutshala Kwemali Elahlekile Elahlekile Kusho Ukubuza Imibuzo Elungile
Ungabuzi ukuthi "Ingabe unaso isitifiketi se-ISO?" Buza: "Uwaqinisekisa kanjani amandla egobolondo ngaphambi kokukhishwa kwe-wax?" Ungabuzi ukuthi "Yimaphi ama-alloys owakhayo?" Buza: “Ngibonise amalogi akho okugcina amathathu okugcina okushisa e-AMS 5387—kanye nemiphumela yokuqina ehambisana nayo.” Ungabuzi ukuthi "Siyini isikhathi sakho sokuhola?" Buza: “Ukuphatha kanjani ukukhukhuleka kwe-dimensional phakathi kokusakaza nokuqeda kokugcina kurola ye-winch centre ye-shaft engu-450 mm?” Izimpendulo zembula ukuvuthwa kokusebenza. QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD. iphendula leyo mibuzo ngezinqubo ezibhaliwe, hhayi izithembiso. Sisebenzela abakhiqizi bephampu yenkundla kawoyela yaseNyakatho Melika abadinga ukuthotshelwa kwe-ASME B16.34, abahlinzeki bezimoto zobunjiniyela baseJalimane abadinga ukulandeleka kwe-EN 1559-3, kanye nabakhi bephampu abakhethekile base-Southeast Asian abafuna izindawo zokuvala i-Ra ≤ 0.8 µm—konke kusuka kumugqa owodwa ohlanganisiwe. Ukusakaza okunembayo akukhona ukuqeda ukuhluka. Kumayelana nokukala, ukumepha, nokuyiphatha—konke ukushisa, yonke indawo, yonke ingxenye.
