Lapho onjiniyela abakudizayini yesistimu ye-hydraulic noma ukuthengwa kwempahla yendawo kawoyela befuna "ifektri ye-advanced precision machining inc," abafuni umhlinzeki wejenerikhi. Badinga uzakwethu oxazulule inkinga efanayo yokuzinza kwe-dimensional ku-AMS 5387 cobalt alloy pump housings—kabili—futhi abhale ukuthi isikhathi sokwelashwa kokushisa sikuthinte kanjani ukwakheka kwe-microcrack kumabhobho asekelwe ku-T800 ngaphansi kokulayisha umjikelezo ongu-280 MPa.
Ukunemba komhlaba wangempela kuqala lapho izitaki zokubekezelelana zigcina khona
Sibone izindlela ezintathu zokuhluleka eziphindelelayo ezingxenyeni zamavalvu anomfutho ophezulu: okokuqala, ukuhlanekezela okushisayo ngesikhathi somshini wokuqeda wezindlu zamasilinda ezinezindonga ezincane; okwesibili, imvula engaguquki yomngcele wokusanhlamvu we-carbide ezisekelweni ze-sand-cast iron; okwesithathu, ukungaboni ngaso linye kwe-GD&T phakathi kokusakazwa kwedatha yedatha nezici zokugcina ze-CNC. QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD. ayilwi nalokhu ngama-specs abanzi-kodwa ngokulawula lonke iketango: ukusuka ekulandeleleni kwe-billet ye-AMS 5387 eqinisekisiwe kuya emijikelezweni yokukhulula ukucindezeleka kwangemva komshini ogunyazwe ngokumelene namajika aqinile we-ASTM E8M. Indawo yabo ethobela i-ISO e-Qingdao ayigcini nje ngokubamba u-±0.01 mm emibikweni ye-CMM—ibambe lokho kunemba *ngemuva* kwamahora angu-48 wokuhamba ngebhayisikili elishisayo ku-120°C, ngoba yilokho okufunwa ama-piston pump assemblies ekusebenzeni kwangempela.
Ukuhlanganiswa okuqondile akuyona i-buzzword-umshuwalense we-dimensional
Abahlinzeki abaningi bakhipha izinsiza zangaphandle noma ukuqeda. Lokho kudala izikhala ze-handoff: i-Foundry ingase ihlangabezane nama-specs e-ASTM A48 Class 35 ensimbi empunga, kodwa ubulukhuni bayo obuphezulu bungagudluza indlela yamathuluzi e-CNC ukujula ngo-0.03 mm—okwanele ukubangela ukuphazamiseka kuma-valve spools. I-QINGDAO QIANGSENYUAN ingumnikazi womabili imigqa yokutshala imali kanye nezikhungo zemishini ye-axis engu-5 ngaphansi kophahla olulodwa. Uma ikhasimende lithumela umdwebo we-winch center shaft roller yemoto yobunjiniyela, ithimba labo lenza izifaniso ezifanayo: ukuhlaziya ukugeleza kwesikhunta *kanye* namamodeli wokuphambuka komshini—lisebenzisa idatha yendawo ebalulekile efanayo. Umphumela? Awekho amalophu okusebenza kabusha. Cha "sicabange ukuthi uzocacisa ukwelashwa kokushisa." Iphakheji elilodwa nje le-GD&T, uhlelo olulodwa lokuhlola, inombolo yeqoqo elilodwa elilandelekayo ukusuka ekuthululeni kuye ekudluleleni phambili.
Awukhethi ama-alloys-ukhetha izindlela zokuhluleka
Izingxenye ze-cobalt-nickel azikhethelwa ukuvelela. Bakhethwa ngoba ezinye izindlela ziyahluleka. Silandelele ukubuyiselwa kwenkambu kumapulaki wepompo angasogwini: izinguqulo zensimbi engagqwali zibonise ukugaya ngemva kwemijikelezo engu-1,200 ku-180°C; I-Inconel 718 ithuthukise i-micro-pitting kumaza okudlidliza adalwe ukugeleza angaphezu kuka-3.2 kHz. Imibhobho ye-cobalt alloy avela kulo mkhiqizi-owenziwe esitokisini se-T800 enokusabalalisa kwe-carbide okulawulwayo-agijime imijikelezo engu-14,700 ngezimo ezifanayo ngaphambi kokushintshwa okuhleliwe. Kungani? Hhayi nje ukwakheka—inqubo yabo ivala ubulukhuni (42–46 HRC) *kanye* nengcindezi eyinsalela ecindezelayo endaweni engaphezulu, iqinisekiswa ngemephu yokucindezeleka eyinsalela ye-XRD kuyo yonke indawo yokukhiqiza. Uma uhlelo lwakho lokusebenza ludinga>impilo yesevisi yamahora angu-300 ezindaweni ezinodaka olubi, lowo mehluko awukhuphuki. Yisikhathi sokusebenza.
Ukuthembeka kokulethwa kuqala ekubuyekezweni komdwebo
“Ungakwenza lokhu?” umbuzo wokuqala ongalungile. Okulungile ukuthi: "Yini ezophuka kuqala - futhi siyimisa kanjani?" Phakathi nokubuyekezwa konjiniyela, ithimba le-QINGDAO QIANGSENYUAN lihlaba umkhosi izingozi zokwenziwa abathengi abaningi abazigejayo: i-engeli esalungiswa engu-0.5° evalela isihlabathi emaphaketheni afakwe ukhonkolo, isilinganiso sembobo eyimpumputhe-to-diameter esidlula u-8:1 sokuqina kokubhoboza imigodi ejulile, noma intambo engajwayelekile ephoqelela ukwenziwa kokuthepha ngokwezifiso kwezinsuku ezingu-1— Babuyisela imidwebo enezichasiselo nezinye izindlela: “Sebenzisa i-ISO 261 M12×1.25 esikhundleni se-pitch yangokwezifiso engu-1.18mm—umsebenzi ofanayo wokuvala, ukulethwa okusheshayo kwezinsuku eziyi-6.” Lokhu akunciphisi izindleko. Ukuqedwa kwengozi ngaphambi kokusika insimbi. Ukuhlela kwabo okuhlelekile kusingatha ukuphindaphinda kwe-prototype kanye nokugijima kwevolumu emaphakathi (ama-pcs angu-50–500) ngaphandle kokushelela kweshejuli—ngoba izinqubo zokugeleza komsebenzi ezithambile zibhakwa zibe amashidi omzila, angengezwe njengocwaningo lwangemva kwenqubo.
Emaqenjini omhlaba okuthenga asesha "imboni ye-advanced precision machining inc," isignali ayilona ulimi lokumaketha. Ubufakazi: izitifiketi zezinto ezibonakalayo ezilandelekayo kukho konke ukuthunyelwa kwe-AMS 5387, imibiko ye-CMM ebonisa ukuchezuka kwesimo sangempela <0.008 mm ezisekelweni zephampu ye-datum engu-12, kanye namalogi okuhlola asebenzayo aqinisekisa amazinga okuvuza kwevalvu yokucindezela ku-1.5× ingcindezi yokusebenza elinganiselwe. Yilokho okuyisisekelo-hhayi okuhlukile. Njengoba amasistimu asebenza ngamanzi aphushela ku-400 MPa wengcindezi yokusebenza kanye namaphampu asendaweni kawoyela adinga izikhawu zesevisi yeminyaka engu-20 ngaphandle kokuhlakazwa, ukunemba komshini kuyeka ukuba mayelana nezingxenye. Iba mayelana nokusebenza okubikezelwayo. QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD. yakha lokho kubikezela—ipulaki eyodwa ye-cobalt alloy, indlu yepiston eyodwa, isilinganiso esisodwa esiqinisekisiwe ngesikhathi.
