Xa iinjineli zichaza a i-metal shaft factory kumacandelo e-mission-critical components-shafts centre shafts under 300 bar, cobalt-alloy nozzles in sour-gas environments, okanye ii-winch rollers kwizithuthi zobunjineli be-offshore-ayifuni nje umatshini. Bafuna isiqinisekiso se-metallurgical, ukuphinda-phinda okulinganayo, kunye nonyamezelo lwe-zero lwe-microstructural drift kwiibhetshi.
Sibone iiprojekthi ezininzi zilibazisekile-hayi ngeziphene zoyilo, kodwa ngezithuba zababoneleli ekuphatheni ialloy. Umthengi wake wasithumelela umzobo wezindlu wempompo ye-cobalt ye-AMS 5387 oneefowuni ze-GD&T ze-±0.005 mm cylindricity kwibhore eyi-120 mm. Umthengisi wabo wangaphambili wayicaphula-kodwa akakwazanga ukubamba ukuphambuka konyango lobushushu ngaphantsi kwe-0.02 mm. Inxalenye yadlula i-CMM kwindawo yokushisa, yasilela uvavanyo olusebenzayo kwi-temp yokusebenza. Ayisiyongxaki yomatshini leyo. Kukusilela kwenkqubo-yokudibanisa izinto.
Kutheni ubuchule bezinto eziphathekayo buhlula abavelisi be-shaft abachanekileyo kwiivenkile zemisebenzi ngokubanzi
I-cobalt-nickel alloys efana ne-T800 kunye ne-AMS 5387 "ayinzima kumatshini" kuba i-brittle. Banzima ngenxa yokuba i-microstructure yabo iyamelana nokuthamba kwe-thermal-kwaye ukuzinza okufanayo kubenza bathande ukusebenza nzima, i-edge eyakhelweyo, kunye nokwahlulwa kwesigaba esingaphantsi komhlaba ukuba ukupholisa amazinga okupholisa okanye imijikelezo yokunciphisa uxinzelelo iyaphambuka nakwi-15 ° C.
Kwi-QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD., yonke i-cobalt-alloy shaft iqala nge-certified billet elandelekayo kwiingxelo zovavanyo lokusila-kungekhona nje ibakala, kodwa umxholo wekhabhoni, i-boron, kunye nesilicon ngaphakathi ± 0.02%. Siqinisekisa ngokubambisana i-chemistry enyibilikayo kunye nababoneleli bethu bezinto eziphathekayo ngaphambi kokuphosa. Ngoba? Ngenxa yokuba i-0.003% ye-boron engaphezulu kwi-AMS 5387 yonyusa umngcipheko wokutshisa ngexesha lotyalo-mali nge-40%, ngedatha ye-ASTM E1268 esiyiqinisekisile ngo-2023.
Oku akuyothiyori. Kulo nyaka uphelileyo, i-OEM yobuchwephesha yaseYurophu yayidinga i-220 mm yepiston yedayamitha yezindlu zesilinda ezineziphazamiso zangaphakathi. I-Standard CNC ijika amanqaku engxoxo ekhohlo asasaza iintanda zokudinwa kwi-12,000 PSI ngebhayisekile. Sitshintshele kwi-hybrid processing: utyalo-mali olufakwe kufutshane ne-net shape + luthomalalise uxinezeleko + lugqitywe ngoomatshini kwiileyile ezi-5 ezithe tyaba ezithe tyaba ezine-vibration yexesha lokwenyani. Isiphumo: uburhabaxa bomphezulu i-Ra ≤0.4 µm, ubunzulu be-spline bugcinwe kwi-0.008 mm ngaphezu kwe-300 mm ubude—nasemva kovavanyo lwesitshizi setyuwa lweyure ezingama-200.
Ukudityaniswa okuthe nkqo akusiyo i-buzzword-kuphela kwendlela yokulawula ingqibelelo ye-shaft
Uninzi “lokuchaneka kweshaft” ababoneleli ngabaxhasi bangaphandle, unyango lobushushu, okanye ukugqiba. Oko kwaphula uxanduva. Ukuba ishafti yeziko le-winch yentsimbi engenastainless ayiphumelelanga ekuqinisekiseni ubulukhuni emva kobushushu, ngubani oyena nobangela? Isiseko? Umsebenzisi weziko? Umatshini osuse i-decarburized layer?
I-QINGDAO QIANGSENYUAN isebenza kwindawo enye ehambelana ne-ISO apho ukuphosa, i-multi-axis CNC, unyango lobushushu, kunye nokugqitywa komphezulu kwenzeka phantsi kophahla olunye-kunye nenkqubo enye yomgangatho. Yonke i-shaft ifumana:
- Ukuqinisekiswa kwezinto ezikrwada nge-OES spectrometry (hayi nje iicerts)
- Ukuhlolwa kwe-CMM kwinkqubo kwizigaba ezithathu: ukutshisa kwangaphambili, ukunyanga emva kobushushu, ukugqiba ukugqiba
- Ukuhlolwa kokugqibela usebenzisa i-profilometry ye-optical kwiindawo ezibaluleke kakhulu zokutywinwa
- Ukulandelwa kweqashiso eligcweleyo: I-ID enyibilikayo, ilog yesithando somlilo, idatha yokunxiba isixhobo, i-ID yomsebenzisi
Asihlangani nje ne-ASME B16.5 okanye i-ISO 2768-mK. Senza imephu ukuba inyathelo ngalinye lenkqubo lichaphazela njani ukusebenza kokugqibela. Umzekelo: Isiseko sempompo yentsimbi esantiweyo ifuna ukupholisa okulawulwayo ukunqanda ukudityaniswa kwamaqhuqhuva egraphite. Sibeka iliso kwii-curves zokupholisa ngee-thermocouples ezifakwe ngaphakathi-hayi nje i-ambient temps. Yiyo loo nto izindlu zethu ze-EN-GJS-400-15 zihlala zifikelela kwi-420 MPa amandla okuqina, hayi ubuncinci be-370 MPa.
Ukuhanjiswa kwehlabathi lokwenyani kuthetha ukusombulula into engekho kumzobo
Inkampani yaseMntla Melika yenkonzo ye-oyile isithumelele umzobo weshafti engekho semgangathweni wewinch yolwandle olunetorque ephezulu. Akukho nto ibonakalayo-nje "i-corrosion resistant, 150 kN static load." Siye saqhuba i-corrosion modeling ngokuchasene ne-NACE MR0175/ISO 15156 bume, i-cross-referenced fatigue curves ye-UNS S32750 vs. Inconel 718, kunye ne-UNS S32760 ecetywayo ene-duplex anneal + shot peening. Bazigcinele i-28% vs. i-nickel alloy cost-ngaphandle kokunciphisa i-chloride ye-SCC ukumelana.
Le yinkqubo eqhelekileyo-hayi ngaphandle. Iqela lethu lobunjineli lihlala libonisa imingcipheko yokwenziwa kwezinto ngexesha lokuzoba: amacandelo anodonga olucekethekileyo oluthanda ukugqwetheka, iimpawu zokunyamezelana ezifuna izixhobo ezingezizo ezisemgangathweni, izitaki ze-GD&T ezingqubana neCPk efikelelekayo. Sibuyisela impendulo kwiiyure ezingama-48-hayi "siya kuyicaphula," kodwa "nantsi indlela esinokuyenza ngayo, kwaye nantsi urhwebo ngexesha lokukhokela kunye neendleko."
Ukuba ufuna i i-metal shaft factory ephatha ivalve yakho yoxinzelelo lwezindlu njengenxalenye ye-flight-critical component-hayi i-commodity part-ukhangela i-alloy discipline eqinisekisiweyo, ulawulo lwenkqubo evaliweyo, kunye nomgwebo wobunjineli othetha ngesinyithi esicacileyo, i-GD & T, kunye neendlela zokusilela endle. Hayi nje umthamo we-CNC. Hayi nje ukukhupha ivolyum. Ukuchaneka, kubambelele kwinyaniso yezinto eziphathekayo.
