Xa iinjineli zicacisa ivalve yoxinzelelo lwenkqubo yehydraulic esebenza kwibhari ye-420-okanye xa amaqela olondolozo ethatha indawo yendlu yesilinda yempompo yepiston kwindawo yokulawula ioli ekude nonxweme-ayifuni nje iinxalenye. Bayayidinga umzi-mveliso wamacandelo amaqabane aphatha uzinzo lwe-dimensional njengekhontrakthi, ukungaguquguquki kwesinyithi njengomnqophiso, kunye nokuhanjiswa kwexesha njengosuku lokugqibela.
Yingakho amacandelo achanekileyo-abalulekileyo-izixhobo ze-hydraulic, izithuthi zobunjineli, i-oyile kunye ne-gas infrastructure, kunye ne-high-duty-duty pump assembly-yandisa ukujika kubavelisi ngokudibanisa ngokuthe nkqo, i-alloy-specific process discipline, kunye nokunyamezela kwe-batch-to-batch drift. Ayizizo zonke izinto ezifumanekayo ezinokubamba ± 0.015 mm kwisitulo somlomo we-cobalt-nickel. Ayizizo zonke iivenkile ze-CNC ezinomatshini we-AMS 5387 ngaphandle kokuqhekeka kwe-micro okanye ukutshatyalaliswa kwendawo echaphazelekayo kubushushu. Kwaye bambalwa kakhulu badibanisa zombini izakhono phantsi kophahla olulodwa oluhambelana ne-ISO-ngelixa ugcina ukulandeleka kwezinto ezibonakalayo ukusuka kwi-T800 ingot ye-alloy ukugqiba i-shaft roller engekho-standard.
Kutheni ubuchwephesha be-alloy bungakhethi-Sisihluzo sokuqala
I-cobalt-nickel superalloys njenge-AMS 5387 kunye ne-T800 ayikhethwanga kwi-aesthetics. Zicaciswe apho ukuxhathisa ukhukuliseko, ukuzinza kwe-thermal ngaphezulu kwe-650 ° C, kunye namandla okuqina ngaphezulu kwe-1,100 MPa ayinakuthetha. Kodwa ukuqina kwabo (45-52 HRC as-cast) kunye ne-thermal conductivity ephantsi kubenza bangaxoleli kwi-machining. Siye sabona abathengi bethumela imizobo bethatha iindlela zesixhobo eziqhelekileyo-kwaye bafumana iinxalenye ezinamanqaku encoko, i-subsurface micro-fractures, okanye i-surface decarburization engaphumelelanga kuvavanyo lokungena kwedayi.
Ukulungiswa akusiyo i-spindles ekhawulezayo. Iiparamitha zokusika eziqinisekisiweyo kwangaphambili, izixhobo ze-carbide kunye neengubo ze-PVD TiAlN, amanqanaba okupholisa alawulwayo angaphantsi kwe-12 ° C, kunye nokujongwa kwe-thermal. Kwiziko lethu le-Qingdao, wonke umsebenzi we-cobalt alloy uqala ngophononongo lwe-metallurgical-hayi nje ikhemistri, kodwa ubungakanani bokusasazwa kweenkozo kunye nembali yonyango lwangaphambili lobushushu. Sifumana kuphela iibhilethi ze-T800 eziqinisekisiweyo ezineengxelo zovavanyo lokusila ezinokulandelelwa kwi-ASTM B572 kunye ne-AMS 5719. Akukho ngaphandle.
Udibaniso oluthe nkqo olunikezela ngozinzo
Uninzi lwababoneleli be "one-stop" banikezela ngaphandle okanye ukugqiba. Oko kudala iingongoma ezintathu zokungaphumeleli: ukungahambelani njenge-microstructure echaphazela ubugcisa; ukutshintshwa kwe-dimensional ngexesha lokunciphisa uxinzelelo; kunye nokwahluka kokugqiba komphezulu kubo bonke abathengisi. Silawula zonke izigaba ezine-utyalo-mali / isanti, i-multi-axis CNC machining (ukuya kwi-5-axis ngaxeshanye), unyango lobushushu (kubandakanywa isisombululo se-annealing + ukuguga nge-AMS 2750), kunye nokugqitywa kwendawo yokusebenza (i-electropolishing, i-shot peening, i-HVOF yokugqoka).
Oku kubaluleke kakhulu kumacandelo afana neziseko zempompo okanye i-winch center shaft rollers. Ezi ayizizo zinyusi ezimileyo-zifunxa umothuko we-torsional, zisasaza i-torque phantsi komthwalo we-cyclic, kunye nojongano olunamatywina aguqukayo. Ukutenxa nge-0.03 mm ekuthwaleni umjikelo wejenali? Oko kukhawulezisa ukunxitywa kwetywina ngama-300% kuvavanyo lwasendle esilufumeneyo kubo bonke abaqhubi beenqwelomoya abali-17 baseMntla Melika. Ukuhamba kwethu okudityanisiweyo kuphelisa i-handoffs. Idatha ye-CMM evela kwii-rough castings feeds ngqo kwi-CNC fixture design. Imijikelo yonyango lobushushu ifakiwe kwiinombolo ze-serial phambi kokusila kokugqibela. Akukho nto ilahlekayo kuguqulo-okanye kuhambo.
Umgangatho owakhelwe ngaphakathi, awuhlolwanga
"Sihlola yonke into" ayinantsingiselo ngaphandle kwamasango achaziweyo. Iprotocol yethu inezithintelo ezine ezinzima: (1) ukuqinisekiswa kwezinto ezingenayo eziluhlaza usebenzisa i-OES spectrometry kunye novavanyo lwe-ultrasonic; (2) ukuhlolwa kwenkqubo emva kokusetyenziswa kakubi ngokusebenzisa i-Zeiss CONTURA G2 CMM kunye ne-Keyence VHX-7000 microscopy yedijithali; (3) ukuqinisekiswa kwe-post-heat-heat-hardness, ukuhamba kwengqolowa, kunye noxinzelelo olushiyekileyo nge-XRD; (4) ukuqinisekiswa kokugqibela kokusebenza-kubandakanywa nokuvavanywa koxinzelelo ukuya kwi-bar ye-600 kunye nokuhlola ukulinganisa okujikelezayo kwiindibano ze-shaft.
Sigcina umkhondo ogcweleyo: inombolo yeqashiso, ilogi enyibilikayo, igophe lonyango lobushushu, ingxelo yeCMM, kunye ne-ID yomsebenzisi zifakwe kwileyibhile ye-QR-coded yecandelo ngalinye. Xa i-OEM yaseYurophu idinga uhlalutyo lwengcambu kwi-valve yokudinwa kwezindlu, satsala irekhodi epheleleyo yemveliso-kubandakanya iigrafu zomthwalo we-spindle ukusuka ekugqibeleni kokugqiba-ngaphakathi kwemizuzu engama-90. Ayikokuthobela oko. Oko kuthembela kubunjineli kulo lonke uluhlu.
Imveliso ethembekileyo iqala ixesha elide phambi kokuba i-chip yokuqala ibhabha. Iqala ngokuqonda ukuba kutheni iplagi ye-cobalt alloy ingaphumeleli kwinkonzo yegesi emuncu-kungekhona ngenxa yekhemistri, kodwa ngenxa ye-oxidation ye-intergranular kwi-machining-induced recast layer. Kuthetha ukwazi ukuba isiseko sempompo yentsimbi esantiweyo yesanti sifuna izibophelelo ezingundoqo ezahlukeneyo zokusasazwa elwandle ngokuchasene nentlango. Kuthetha ukuphatha ii-callouts ze-GD&T hayi njengephepha, kodwa njengenjongo esebenzayo eguqulelwe kulawulo lwenkqubo.
Iinjineli ezifuna izinto zentsimbi ezibaluleke kakhulu, ekunene umzi-mveliso wamacandelo ayingoyena mbhidi uphantsi. Liqabane elibuza ngokusilela kwakho kwintsimi embi kakhulu ngaphambi kokuba ucaphule iodolo yakho elandelayo-kwaye ke yakhe umlinganiselo wokuchasa kwisicwangciso senkqubo. Yiloo ndlela ukuthembeka kuba yinto ephindaphindiweyo.
