Lapho onjiniyela becacisa a imboni ye-level shaft roller, abagcini ngoku-oda ingxenye ejikelezayo—bakhetha ukuxhumana okubalulekile phakathi kokulawula ukunyakaza nobuqotho besakhiwo. Kumasistimu ewintshi emisebenzi ephezulu, amaphampu asebenza ngohydraulic, noma ama-assemblies okulinganisa ngokunemba, i-shaft roller ithwala imithwalo ye-cyclic torsional, i-radial misalignment, kanye nokuthintana okulimazayo. Ukuchezuka okungu-0.02 mm kokuyindilinga kungasheshisa ukuguga ngo-40%. Ukwehluka okungu-5% kokuqina kobuso kumema umgodi omncane phakathi kwamahora okusebenza angama-200. Yingakho ukuthola intengo kungabi ngenani ngekhilogremu. Imayelana nokungaguquguquki kwe-metallurgical, ukuthobela i-GD&T kuzo zonke izigaba, kanye nokungabekezelelani nhlobo kwe-batch-to-batch drift esakhiweni sokusanhlamvu.
Okwenza Ukukhetha Kwezinto Ezibonakalayo Kuphoqelele Ukusebenza—Hhayi Ukwenza Ngomshini Kuphela
Ukwehluleka okuningi kubuyela emuva kumsuka owodwa: ukuziphatha okungafanele okuphathekayo ngaphansi kwengcindezi yomhlaba wangempela. Amarola ajwayelekile angu-42CrMo4 ayaqhekeka lapho evezwe ezindaweni zikawoyela ezinothe nge-sulfide. Izinhlobo ze-AISI 4140 zincipha ngaphansi kokulayisha okuphindaphindiwe komthelela kumawintshi emoto yobunjiniyela. Sibone amakhasimende amathathu ahlukene eshintsha amarola njalo ezinyangeni ezi-3—aze ashintshela ku-AMS 5387 cobalt alloy. I-matrix yayo ye-chromium-tungsten imelana nentukuthelo ku-650°C. Isakhiwo sayo esihle se-dendritic sibamba u-Ra ≤ 0.4 µm ngemva kokugaya okokugcina—okubalulekile ekulandeleni izindebe ze-seal. Kwa-QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD., “Asiqali ngomshini, sihlole kamuva.” Siqinisekisa i-billet chemistry ngaphambi kokusakaza, siqinisekisa ukuhlukaniswa kwe-interdendritic nge-SEM-EDS, bese siqinisekisa ukusatshalaliswa kokuqina kuzo zonke izigaba ezihlukene sisebenzisa imephu ye-micro-Vickers. Yonke i-roller esekelwe ku-T800 yeleveli ye-level shaft ithwala ukulandeleka kwenkatho yokushisa okugcwele—hhayi nje inombolo yesitifiketi, kodwa amalogi omjikelezo oshisayo wangempela namajika aqinile asuka esithandweni somlilo esifanayo.
Ukuhlanganisa Okuqondile Kuxazulula Lokho Okufihliwe Ukutholwa Kwempahla
Abanye abahlinzeki bakhipha imithombo yokusakaza, ukwenza imishini, nokuqedela ukuze bahlukanise abathengisi. Lokho kudala izindawo eziyizimpumputhe: indlu yesanti-cast ingaba ne-porosity engaphansi komhlaba engabonakali ku-NDT-kodwa yembulwa kuphela ngemva kokuba ukugaya kwe-CNC kususa ungqimba lwangaphandle lomsindo. Abanye bayeqa ukwelashwa kokushisa kuze kube yilapho behlangana okokugcina, bebeka engcupheni yokuhlanekezelwa ngesikhathi sokucisha ijometri eqediwe. I-QINGDAO QIANGSENYUAN iqhuba ukufakwa kwe-investimenti, ukujika kwe-CNC okunama-axis amaningi (kufika ku-B-axis swiveling), ukwelashwa kokushisa kwe-vacuum, kanye nokupholishwa ngogesi endaweni eyodwa enesitifiketi se-ISO 9001. Ukuze uthole izindlu zesilinda sephampu ye-piston enamajenali ahlanganisiwe, sishicilela i-bore *ngaphambi* kokuqina—bese sigaya kabusha i-post-temper ukuze sibambe isilinda esingu-±0.005 mm ngaphezu kobude obungu-300 mm. Awekho ama-handoffs. Akukho ukukhukhuleka kwe-dimensional. Akukho ukushintshwa kwecala lapho i-Cpk yehla ngaphansi kwe-1.33.
Ukuqinisekiswa Komhlaba Wangempela Kwedlula Izichasiselo Zephepha
Amakhasimende ayabuza: “Ingabe i-level shaft roller yakho ingaphatha u-12,000 psi pulsation + 1,800 rpm?” Siphendula ngedatha—hhayi izithembiso. Ngonyaka odlule, sihlole okuhlukile okuyisithupha ngaphansi komsebenzi wokulingisa wewintshi yasolwandle: ukuchayeka kwesifutho sikasawoti samahora angu-250, ukuguqulwa kwe-torque engu-10⁶, kanye nokuhamba ngebhayisikili komthwalo oqhubekayo ukusuka ku-0 ukuya ku-220 kN. I-AMS 5387 kuphela enezigaba ezimbili zokuguga (isixazululo esingu-1,100°C + 850°C/4h + 650°C/16h) edlule ngaphandle kokuqhekeka kwendawo noma ukwehla kokuqina >3 HRC. Insimbi engagqwali 17-4PH yehlulekile kumjikelezo ongu-780,000. Kungakho umthetho wethu olandelwayo wokuhlola uhlanganisa ukuskena okungu-100% kwe-ultrasonic kokungaqhubeki kwangaphakathi—futhi kungani yonke impahla ethunyelwayo ihlanganisa umbiko wedijithali onembondela ye-CMM yokuskena ngokumelene ne-CAD yegama, hhayi nje ukudlula/ukuhluleka kwezitembu.
Indlela Yokucacisa Okulungile—Kusuka Ekudwebeni Kuya Ekuletheni
Qala ngenhloso yokusebenza—hhayi ijometri. Esikhundleni sokuthi “Ø120 mm × 450 mm,” chaza: “Kumelwe idlulise itorque engu-85 kN-m kuyilapho igcina ukuphuma kuka-≤ 0.015 mm ngemva kwesevisi yamahora angu-5,000 kuwoyela wamaminerali we-ISO VG 68 endaweni engu-80°C.” Bese uvumela i- imboni ye-level shaft roller ukuqondisa ukukhethwa kwezinto, ukulandelana kokuphatha ukushisa, nokuqeda. Sivame ukuhlaba umkhosi izingxabano ze-GD&T—njengokucacisa ukubekezelela indawo esicini esifakwe ngomshini ngemva kokwelashwa kokushisa, lapho ukucindezeleka okuyinsalela kuzoshintsha indawo ngokungalindelekile. Onjiniyela bethu babuyisela imidwebo enezichasiselo phakathi kwamahora angu-48, egqamisa ubungozi bokwenziwa, iphakamisa amanye ama-alloys, kanye nokucaphuna isikhathi sokuhola kuzo zombili izibonelo (amaviki ama-4) nama-oda wevolumu emaphakathi (amaviki ayi-12–15). Azikho izimanga. Akukho ukusebenza kabusha. Akukho ukulethwa sekwephuzile.
Kuzinhlelo zokusebenza ezibaluleke kakhulu kumgomo lapho ukwehluleka kusho isikhathi sokuphumula, ubungozi bokuphepha, noma ukungathobeli imithetho—ukunemba akuyona inketho. Yakhiwe, yaqinisekiswa, futhi yalethwa. QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD. yakha ama-level shaft roller asindayo-hhayi nje ukuphenduka. Umsebenzi wabo uqala kudala ngaphambi kokuthi kundiza i-chip yokuqala: kumalebhu wesayensi yezinto ezibonakalayo, isoftware yokumodela eshisayo, kanye namashumi eminyaka empendulo yenkambu yesistimu yephampu. Yileyo ndlela i-roller eba ngayo ihange elithembekile.
