Xa indlu yempompo ye-hydraulic iqhekeka ngaphantsi kwe-350 bar, okanye umbhobho we-cobalt alloy ukhukuliseka emva kweeyure ezingama-400 kwinkonzo yerhasi emuncu, iinjineli ziyayeka ukubuza "Simele sisebenzise ntoni?" Bayabuza: “Ngubani onomatshini ukwenziwa kwealloyi yesiko iinxalenye ezingayi kusilela ngomhla wama-47?”
Lo mbuzo awukho ithiyori. Siye sayibona kwii-OEM ezintathu ze-Oilfield yaseMntla Melika kunyaka ophelileyo-nganye ijongene nexesha lokuphumla elingacwangciswanga ngenxa yokuba i-alloys engekho kwi-shelf ayikwazanga ukubamba ukunyamezela kwe-GD & T ± 0.015 mm ngelixa ixhathisa i-chloride pitting kwi-120 ° C. Standard stainless steel warped. I-Inconel 625 inqunyulwe kwingcambu yomsonto. Sinye kuphela isisombululo esibanjiweyo: i-T800 cobalt-based casting, egqityiweyo kunye nokulawulwa koxinzelelo lwe-thermal kunye nokuqinisekiswa nge-CMM kuyo yonke idatha ebalulekileyo.
Apha kulapho i-alloy machining yesiko iyeka ukuba yinto yokuthengwa kwempahla-kwaye ibe yinto yokuthembeka. Ifuna ngaphezulu kwesakhono seCNC. Ifuna uqeqesho lwesinyithi, ukulandeleka kwenkqubo, kunye nobunjineli ngokutyibilikayo kuzo zonke iindawo zojongano zonyango lobushushu. Bambalwa ababoneleli abasebenza kwezo ntlangano-ndlela. Bambalwa abasayibhalayo.
Kutheni iCobalt-Nickel Alloys ifuna ngaphezulu koMatshini "okulunga ngokwaneleyo".
I-cobalt-nickel superalloys efana ne-AMS 5387 okanye i-T800 akunzima ukuyenza kuba "inzima." Banzima ngenxa yokuba izinga labo lokuqiniswa komsebenzi lidlula i-300% ngexesha lokunqunyulwa kokuphazamiseka, ukuqhutyelwa kwe-thermal kuhlala ngaphantsi kwe-12 W / m·K, kunye nokungahambelani kwe-microstructural-nokuba i-5-8 µm ye-carbide yokwahlula-i-trigger i-chatter yesixhobo eyonakalisa ingqibelelo yomhlaba ebusweni bokutywinwa.
Sakhe safumana umzobo we-AMS 5387 pump plunger sleeve enemfuno eyi-0.008 mm Ra kwi-120 mm yangaphakathi. Umboneleli wangaphambili womthengi usebenzise i-carbide esemgangathweni kunye ne-coolant-through spindles. Isiphumo? Iinyembezi zobuso obungama-80 mm ubunzulu, idimensional drift ngaphaya kwe-±0.025 mm, kunye ne-37% yereyithi ye-scrap. Ulungiso lwethu ibingelo "izixhobo ezingcono." Kwakuyizenzo ezintathu ezilungelelanisiweyo: (1) unyango olushushu lwangaphambili kwi-homogenize ukusabalalisa i-carbide; (2) ukugqitywa kweepase ezininzi kunye nokufakwa kwe-ceramic ehamba kwi-42 m / min-ehamba ngokukhawuleza, kodwa ezinzileyo; (3) kwinkqubo yokulinganisa umoya rhoqo nge-15 mm ukulungisa imbuyekezo yesondlo phambi kokuba ukutenxa kudlule kwi-0.005 mm.
Eli nqanaba lolawulo lahlula iindawo ezisebenzayo kwi-mission-criticals. Iivalve zoxinzelelo azivuzi ngenxa yokuba izitywina zifanelekile-ziyavuza xa izibonda zezindlu zigqwetheka phantsi kwetorque ebambayo. Olo jijo luqala kwakudala ngaphambi kokusikwa kokugqibela: ekuhambeni kwezinto eziziinkozo ezikrwada, kuxinzelelo olushiyekileyo olusuka kumazinga okupholisa, kwimithamo eshushu ngexesha lokufunxa. I-custom alloy machining kufuneka ilawule zonke ezintathu-kungekhona nje ukususa isinyithi.
Ukudityaniswa okuthe nkqo akusiyo i-Buzzword-Ngumgca wakho wokuqala woKhuselo
Ezinye iivenkile zikhuphela ngaphandle. Abanye bakhupha unyango lobushushu. Iqela lesithathu lihlola izixhobo zangaphandle. I-handoff nganye yongeza izinto eziguquguqukayo: ikhemistri yebhetshi engahambelaniyo, amaxesha okufunxa isithando somlilo esingabhalwanga, ulungelelwaniso lwegage olungabhalwanga. Xa inxalenye yakho isilela, ukulandelela ingcambu imbangela kubathengisi abathathu kuthatha iiveki-kungekhona iiyure.
E-QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD., ukuphosa, umatshini we-CNC, kunye nokugqiba kwenzeka phantsi kophahla olulodwa oluhambelana ne-ISO-kunye ne-metrology ekwabelwana ngayo, ukulandelwa kwezinto ezidibeneyo, kunye nokuqinisekiswa kwenkqubo edibeneyo. Yonke i-cobalt alloy billet iphethe i-ID ye-QR-coded edibanisa kwingxelo yayo yokuvavanya, ifilimu ye-X-ray, i-log ye-curve yonyango lokushisa, kunye nenqaku lokuqala le-CMM ingxelo. Ukuba i-piston pump cylinder yezindlu ibonisa ukunxiba okungalindelekanga kuvavanyo lwentsimi, sitsala iwele ledijithali elipheleleyo-kungekhona nje iphepha lokugqibela lokuhlola.
Olu hlanganiso luzisa iziphumo ezinokulinganiswa:
- Uzinzo lweDimensional luphuculwe ngama-40% kwimizimba yevalvu yoxinzelelo olubhityileyo (0.8 mm ubukhulu bodonga, Ø142 mm OD)
- Umphezulu ukuphindaphinda ukuphinda kuqiniswe ukusuka ±0.03 mm Ra ukuya ±0.007 mm Ra kwimilomo ye-T800
- Ixesha lokukhokela kumthamo ophakathi we-AMS 5387 iiodolo lincitshiswe ngeentsuku ezingama-22 ngokuchasene namakhonkco obonelelo acandekileyo.
Ikwavumela iinkqubo ezixubeneyo-ezifana ne-T800 cores-cast-cast kunye ne-CNC ekufutshane-netha yokugqiba-ezokuphelisa ii-angles eziyidrafti kunye nokunciphisa ukususwa kwempahla nge-65%. Oko akukongi iindleko. Kukunciphisa umngcipheko owakhelwe kwijometri.
Ukuqinisekiswa Kwehlabathi Lokwenyani: Ithetha ukuthini "Ukuchaneka" Ngokwenyani kwimixholo yoShishino
Ukuchaneka akuchazwa ngofundo lwemicrometer kuphela. Iqinisekisiwe kumsebenzi. Sivavanya zonke izindlu zevalve yoxinzelelo kunye nobungqina be-hydrostatic kwi-1.5 × yoxinzelelo olusebenzayo, emva koko siyijikelezise amaxesha angama-5,000 kuluhlu lwayo lobushushu. Yonke i-winch centre shaft roller ifumana ukuqinisekiswa kwebhalansi eguquguqukayo kwi-3,200 RPM-kunye nokuhlolwa okubonakalayo kwe-subsurface cracking usebenzisa i-fluorescent penetrant nge-ASTM E1417.
Abathengi bahlala bebuza: "Ngaba unokuhambelana nexesha elikhoyo lomthengisi?" Siphendula ngedatha-hayi izithembiso. Ngokomzekelo, imoto yobunjineli yaseYurophu i-OEM yayidinga iiyunithi ezingama-280 zeplagi ye-cobalt alloy (AMS 5387, Ø86 mm × 192 mm, kunye ne-6 imicu yangaphakathi M24 × 2). Umthengisi wabo wangaphambili ucaphule iiveki ze-14, kungekho nkxaso yokuhlaziya. Sihambise amanqaku okuqala kwiiveki ze-6-kubandakanya uphononongo lwe-GD&T, ulungelelwaniso lwesatifikethi sezinto eziphathekayo, kunye nengxelo yokwenziwa kwezinto eyenza lula iiradio ezimbini ezingasebenziyo. Ukuhanjiswa kokugqibela: iiveki ze-10. Zero dimensional rework.
Eso santya savela ekupheliseni iingcamango—kungekhona ukugawula iikona. Saqinisekisa ukuqina kwempahla phambi kokuba roughing. Siqhube ukucuthwa kwetyala kwisitokhwe sedini kubushushu obufanayo. Silinganise ukunxiba kwesixhobo rhoqo ngemizuzu eyi-12-hayi yonke iishifti.
Ukukhetha iqabane leSiko leAlloy Machining: Jonga ngaPhambili kwincwadana
Ukuba iprojekthi yakho elandelayo ibandakanya i-cobalt-nickel, i-high-strength stainless, okanye i-nickel-iron alloys, buza le mibuzo ngaphambi kokuba usayine i-PO:
- Ngaba uyayilawula yonke imbali ye-thermal-ukusuka kwizinga lokupholisa ukuya kumjikelo wokugqibela wokunciphisa uxinzelelo?
- Ngaba unokubonelela ngokulandeleka okupheleleyo kwemathiriyeli ukubuyela kwibhetshi enyibilikayo, kubandakanya iziphumo zovavanyo lwe-intergranular corrosion?
- Uqinisekisa njani uzinzo lwedimensional kumacandelo anodonga olucekethekileyo emva komatshini wokugqibela kunye nokucoca?
- Ithini inkqubo yakho ebhaliweyo yokulawula ukunxitywa kwesixhobo kwi-alloys nge>40 HRC kunye > ne-30% yokusebenza nzima?
Iimpendulo zityhila ngaphezu kobuchule. Babonisa ukuba umthengisi uyayiphatha inxalenye yakho njengento ecacileyo-okanye njengenxalenye yenkqubo eneziphumo zehlabathi lokwenyani.
Ukulungiswa kwe-alloy yesiko akukho malunga nokwenza isinyithi sihambelane nomzobo. Kumalunga nokwenza umzobo ubonise ukuba yintoni isinyithi-kunye nesicelo-inokuthi inikezele ngokwenene. Oko kufuna amava enziwe ngokusilela, ubuchwephesha obungqiniweyo kwiimfumba zokunyamezelana, kunye nentembeko efunyenwe ngedatha elandelekayo-hayi amabango okuthengisa. Xa uxinzelelo lukhula, ukuchaneka kubambe. Khetha ngokufanelekileyo.
