Isesha a Imboni ye-Co1 akukhona mayelana nokuthola noma yimuphi umphakeli ogcina ama-alloys asekelwe ku-cobalt. Imayelana nokuhlonza uzakwethu oqondayo ukuthi kungani i-AMS 5387 cobalt alloy 6 ibambelela ngaphansi kuka-30,000 psi ezindlini zephampu ye-hydraulic—nokuthi kungani i-T800-grade impahla iqhekeka uma ukwelashwa kokushisa kuchezuka ngo-15°C nje. Sibone abathengi be-oda izingxenye ze-“Co 1” ezinkampanini ezihweba ngezigaba ezintathu kuphela ukuze bathole ukusakaza okungaqinisekisiwe okunokwakheka okusanhlamvu okungahambisani. Umphumela? Ukuhluleka kwenkundla kuma-offshore winch center shaft rollers ngemva kwamahora angu-400 okusebenza. Lokho akuyona indaba yezinto. Kuwukwehluleka ukuthola.
Kungani i-“Co 1” Idinga Okungaphezu Kwenombolo Yekhathalogi
Ingxubevange ye-cobalt-chromium ebhalwe ukuthi “Co 1” ayilinganisiwe kuyo yonke imininingwane ye-ISO, ASTM, noma ye-AMS. Lokho omunye umsunguli okubiza ngokuthi i-Co 1 kungase kuhambisane ne-ASTM F75, kuyilapho enye ikusebenzisa ngokukhululekile emixubeni evamile efana ne-Stellite. Ukusebenza komhlaba wangempela kuncike ekulawuleni ukwakheka okunembayo—ikakhulukazi i-chromium (27–33%), i-tungsten (4–6%), nekhabhoni (0.9–1.4%)—kanye nokubambelela ngokuqinile emazingeni okupholisa okuqinisa ngesikhathi sokutshala imali. Sake sahlola abahlinzeki abahlanu abacaphuna “ama-nozzles e-Co 1” ukuze bathole izicelo zokushisa uwoyela ezishisa kakhulu. Zimbili kuphela izingxenye ezilethiwe ezidlula i-ASTM A957 nezidingo zomthelela ku-−40°C. Okunye okusele kuhlulekile ukuqinisekiswa kwe-microstructure-i-porosity ebonakalayo nokuhlukaniswa kwe-carbide ngaphansi kokukhulisa okungu-100×.
Izihlungi Ezine Ezingaxoxiswana Zefektri Ethembekile ye-Co 1
- Ukulandelelwa kwe-Metallurgical-hhayi nje izitifiketi zokugaya. Cela imibiko ye-spectrographic eqondene nenqwaba, amalogi okwelapha ukushisa, kanye nama-micrographs as-cast. A iqiniso Imboni ye-Co1 igcina izitifiketi zezinto ezingavuthiwe *futhi* izixhumanisa nengxenye yokugcina yezinombolo ze-serial. Akukho okuhlukile.
- Amandla wokwenza imishini yasendlini okulawula i-post-cast geometry. Ama-cobalt alloys asebenza kanzima. Uma ipulaki yakho ye-Co 1 idinga ukubekezelela i-ID engu-±0.005 mm, ukugaya ngemva kokusakaza kuyisibopho. Ukuqedwa kokuthunyelwa kwempahla kwabahlinzeki bangaphandle kwethula amaphutha okuqondanisa, ukulahleka kobuqotho obungaphezulu, kanye nengcindezi eyinsalela engalawuleki.
- Umlando wohlelo lokusebenza ofakazelwe emkhakheni wakho. Isitolo esenza izihlalo zamavalvu e-Co 1 zama-steam turbines sinolwazi lwenqubo oluhlukile kunelodwa elihlinzeka ngezindlu zesilinda sephampu ye-piston yamayunithi okuqhekeka okuqhutshwa ngamanzi. Ukufuna izithombe zokukhiqiza kuyasebenza—hhayi izithombe zesitoko.
- Isibuyekezo sobunjiniyela be-GD&T-aware—hhayi nje ukudweba ukwamukelwa. Uma uthumela ingxenye enokubekezelela indawo ku-Ø12 mm bores ehlobene nendiza yedatha, umphakeli kufanele amake ukuthi ama-engeli asalungiswa okukhipha isihlabathi azokwephula izindawo zokuxhumana ezisebenzayo. Sibone u-30% wemifanekiso yokuqala ye-Co 1 echithwa ngenxa yokuhumusha okungahloliwe phakathi kwephethini yokusakaza nokusethwa kwe-CNC.
Kwenzekani Uma Weqa Ukuhlanganiswa Okuqondile
Abanye abathengi bakhetha izisekelo ezingabizi kakhulu zokusakaza, bese behambisa izingxenye ukuze bahlukanise izitolo ze-CNC ukuze ziqedwe. Leyo modeli iyehluleka ngezingxenye ze-Co 1. Kungani? Ukuhlanekezela okushisayo ngesikhathi sokwelashwa kokushisa okwehlisa ingcindezi kushintsha ubudlelwano bobukhulu. Isilinda sezindlu esinogqinsi oluphelele luba lubi ngemva komshini uma umakhi wemishini engawazi umlando oshisayo oqondile kanye nemephu yokucindezeleka eyinsalela. QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD. igwema lokhu ngokulawula ukusakaza, ukwelashwa kokushisa, ukwenziwa kwemishini ye-multi-axis, kanye nokuqedwa kwendawo ngaphansi kophahla olulodwa oluthobela i-ISO. Ukuhlolwa kwabo kwe-CMM kwenzeka *ngemuva* kokukhululeka kokucindezeleka kokugcina—hhayi ngaphambili. Lokho kulandelana kukodwa kunciphisa ukusebenza kabusha kwemizimba yama-valve ngo-65% kumaphrojekthi ethu ahlangene.
Izinyathelo Ezilandelayo Ezisebenzayo—Hhayi Iseluleko Kuphela
Ngaphambi kokucela ikhotheshini, thumela umdwebo wakho bese ucela izinto ezintathu: (1) indlela yabo yokufaka ehlongozwayo (ukutshala imali uma kuqhathaniswa ne-centrifugal), (2) ukuthi bazoqinisekisa kanjani ukuthobela kwe-AMS 5387 nge-AMS 2249 ngayinye, kanye (3) namarekhodi okuhlola amasampula avela engxenyeni efanayo yomndeni. Nqaba izimpendulo ezicaphuna "umkhuba ojwayelekile" noma "inkambiso yemboni." Udinga ubufakazi obubhaliwe—hhayi iziqinisekiso. Futhi, cela isithombe esinezingxenye ezihlukene endaweni yabo yokugcina ye-Co 1. Bheka ukuhlakazeka kwe-carbide efanayo kanye nokungabikho kwemigodi eshwabene eduze nezingxenye eziwugqinsi.
A okuthembekile Imboni ye-Co1 ayikhangisi "ikhwalithi engcono kakhulu." Ikubonisa ubulukhuni begradient yonkana ithiphu le-T800 alloy nozzle. Yabelana ngombiko wayo wenkatho enqatshiwe lapho ukushisa kuwela ngaphandle kwe-Rockwell C 42–48 spec. Yakha ama-prototypes anokulandeleka okugcwele—hhayi nje ukuthobelana, kodwa ngoba iyazi ukuthi ukuhlanganiswa kwephampu yakho ngeke ikubekezelele ukuhluka. Leso siyalo sihlukanisa abahlinzeki nozakwethu. Futhi yilapho ukunemba kuqala khona.
