Uma isistimu ye-hydraulic ihluleka ngaphansi kwengcindezi yamabha angu-350, umlandu akavamile ukuba abe iphampu-ingxenye yevalvu ye-homogenizing. Sikubone kathathu kulo nyaka kuphela: ukugeleza okungahambisani, ukuqhekeka okushisayo ngemva kwemijikelezo engu-420, ukuguguleka kwezihlalo ngaphambi kwesikhathi emibhobho ye-cobalt-alloy. Ukwehluleka ngakunye kulandelelwa emuva kumsuka owodwa—ukuzinza kwe-dimensional okunganele kuzo zonke izingxenye zengxubevange ye-T800 efakwe ukushisa. Yingakho onjiniyela befuna I-Homogenizing Valve ingxenye yefekthri ozakwethu ababuzi ukuthi "Ungakwazi?" Babuza ukuthi “Ungabamba u-±0.015 mm ku-220 mm bore ngenkathi ugcina ubuqotho be-AMS 5387 microstructure ngokukhululeka kokugcina kwengcindezi?”
QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD. iphendula lowo mbuzo ngesiyalo—hhayi izithembiso. Isekelwe e-Qingdao, inkampani isebenzisa indawo ethobela i-ISO lapho ukulingisa, ukwenza imishini ye-CNC, nokuqeda kungekona ukunikezwa okulandelanayo—kuyizigaba ezivumelanisiwe ngaphansi kweluphu eyodwa yokulandelela ikhwalithi. Lapho iklayenti lihambisa umdwebo we-GD&T-heavy wezindlu zesilinda sephampu yepiston, onjiniyela ababheki nje ukubekezelelana. Balingisa izindlela zokuhlanekezela okushisayo, baqinisekise ukungakwazi ukunyakazisa isikhunta sesihlabathi ngokumelene namagradients odongeni, futhi baqinisekise kusengaphambili izingozi zokungqubuzana kwendlela yamathuluzi emishinini yangempela yama-eksisi angu-5—ngaphambi kokusika insimbi yokuqala.
Amaqiniso amathathu obuchwepheshe ahlukanisa lokhu I-Homogenizing Valve ingxenye yefekthri kusuka kubahlinzeki bezinjongo ezijwayelekile:
- I-cobalt-nickel alloy mastery ayiyona ithiyori—iyalinganiswa. Izingxenye ze-AMS 5387 zithola ukwelashwa okumbaxambili kokushisa (isixazululo se-anneal ku-1175°C + ukuguga kokuthi 845°C), ngama-thermocouples esithandweni amephuwe abe ngu-±1.2°C kuzo zonke izindawo zokulayisha ezingu-1.8 m³. Iqoqo ngalinye lithola ukuqinisekiswa kwe-spectrographic—asikho “isitifiketi esibalulekile esicatshangelwayo.”
- Ukulawulwa kobukhulu kuqala ngaphambi komshini. Ukulingisa insimbi yezisekelo zephampu kusebenzisa amasistimu okukhuphuka okupholisa alawulwayo anciphisa ingcindezi eyinsalela ngo-38% uma kuqhathaniswa ne-gating evamile—okukalwa nge-X-ray diffraction kumasampula cores, okungalinganiselwa.
- Ubuqotho bobuso bufana nesidingo sokusebenza. Isihlalo sevalvu ye-homogenizing asidingi u-Ra 0.4 µm yonke indawo—sidinga u-Ra 0.2 µm ebhandeni lokuvala, i-Ra 1.6 µm ku-vent groove, kanye nengcindezi ecindezelayo esalayo elawulwayo (−320 MPa) phakathi kokushona komhlaba okungaphansi kuka-0.15 mm. Lokho kufinyelelwa ngokuqedela okuxubile: ukugaya okunembayo okulandelwa ukuchama kweshothi elinamandla amancane, kuqinisekiswe ngemicu ye-Almen nezingxenye eziphambanayo ze-SEM.
Abanye bangase baphikise ngokuthi ukuhlanganiswa kwe-offshore casting-machining kumema ukunensa kwezokuxhumana noma izikhala zemibhalo. Kodwa empeleni, silandelele ama-oda esibonelo angu-17 kuzo zonke izimakethe zaseNyakatho Melika kanye ne-EU—futhi konke ukubuyekezwa konjiniyela kuhlanganisa ukwabelana kwesikrini kwesikhathi sangempela semibiko ye-CMM embozwe kumamodeli e-CAD, anezichasiselo ze-callout ze-GD&T ezinesitembu sesikhathi. Cha "sizokucacisa kamuva." Cha “ngokokuqonda kwethu.” Ukuqinisekisa bukhoma nje: "Lokhu kuchezuka okungu-0.02 mm kuwela ngaphandle kokucaciswa kwakho-nali imephu eshisayo ebonisa ukuthi kungani, futhi nansi idizayini yethu ebuyekeziwe yokuyilungisa."
Inkokhelo ibonakala ekusebenzeni kwenkambu. Iklayenti elilodwa laseNingizimu-mpumalanga ye-Asia lishintshe imizimba yama-valve yefa lehluleka emahoreni okusebenza angu-14,000 ngenguqulo ye-QIANGSENYUAN ye-T800 alloy. Ngemva kwamahora angu-28,500—ngaphansi kuka-290°C okuqhubekayo, umsebenzi wamabha angu-310—amayunithi aphumelele ukuhlolwa kwe-ultrasonic ngokunqanyulwa kwe-zero subsurface. Hhayi "kusasebenza." Kuqinisekisiwe njengoba kunjalo. Lokho kwethembeka kusuka ekuhlanganisweni okuqondile: ithimba elifanayo likhetha ingot ye-cobalt, lenza okungenalutho, lenza i-port geometry, futhi lisebenzisa okokugcina kwe-nitride. Akukho ukukhishwa kusho ukuthi akukho okuguquguqukayo okufihliwe—akukho ukukhula okungalawuleki kokusanhlamvu ngesikhathi sokudluliselwa phakathi kwezinsiza, akukho ukungcoliswa komhlaba okungabhaliwe ngaphambi kokucwetshwa.
Okwamaqembu okuthenga ahlola a I-Homogenizing Valve ingxenye yefekthri, qala ngemibuzo emithathu: Okokuqala, bangakubonisa imibiko yokuhlolwa komshini wezinto ezingavuthiwe *yenombolo yakho ye-oda*—hhayi izitifiketi ezijwayelekile? Okwesibili, ingabe imibiko yabo ye-CMM ihlanganisa ukuhlolwa okuphelele kwe-GD&T (hhayi nje ukuthi “KULUNGILE/NG” kudlula/kwehlule)? Okwesithathu, iyiphi inqubo yabo ebhaliwe yokuphatha ubukhulu obungavumelani phakathi nenqubo—ukusebenza kabusha, ukulahlwa, noma ukuyekwa kobunjiniyela? I-QINGDAO QIANGSENYUAN ishicilela bobathathu ngokwesicelo. Indlela yabo ayikona ukugwema ukwehluleka. Imayelana nokwakha ukutholwa kuzo zonke izigaba—ngakho-ke lapho ukuchezuka okungu-0.008 mm kuvela kunqubo, kubangela ukubuyekezwa kwe-metallurgical ngokushesha—hhayi isikhalazo sekhasimende sangemva kokuthunyelwa.
Uma ubheka phambili, inselele ayikona ukukhuphula umkhiqizo-ijulisa ukunemba kokusebenza. Isigaba esilandelayo i-R&D igxile ezinqubweni eziyingxubevange: imizimba yamavalvu e-investment-cast enamashaneli okupholisa afakwe ngomshini, lapho ukulingisa okushisayo kushayela kokubili ukwakheka kwesikhunta nokulandelana kwendlela yamathuluzi ye-CNC. Igoli? Bamba isilinda esingu-0.01 mm kumadayamitha angu-300 mm ngaphandle kokuqondisa kwangemuva kokwelashwa. Lokho akukhona ukuthuthuka okuqhubekayo. Lokho kuchaza kabusha ukuthi kusho ukuthini “ukusebenza okuphezulu” kumavalvu e-homogenizing—i-micron eyodwa eqinisekisiwe ngesikhathi.
