Imveliso yonyamezelo oluphezulu ifuna ngaphezulu kunee-specs eziqinileyo-ifuna ukuqeqeshwa kwenkqubo, ukuphatha izinto eziphathekayo, kunye noxanduva lokuphendula kwinqanaba ngalinye. Xa indlu yempompo ye-hydraulic ihluleka phantsi koxinzelelo lwe-350-bar, okanye i-cobalt alloy nozzle ikhukhula emva kweeyure ezingama-200 kwinkonzo yegesi emuncu, unobangela wengcambu awufane ube ngumzobo. Ngumsantsa phakathi kwentelekelelo yokuncipha kunye nokuziphatha okuqiniswayo. Yeyona gradient ye-thermal engalawulwayo ngexesha lonyango lobushushu lwe-AMS 5387. Yi-CMM probe angle misalignment kwi-0.015 mm GD&T callout ye-piston cylinder bore. Sizibonile zontathu-kwaye sizilungisile hayi ngeendlela zokusebenza, kodwa ngokudibeneyo umzi-mveliso weenkqubo zokuphosa ngokuchanekileyo ukubulawa.
Kutheni ukunyamezelwa kokuphosa ingekho nje malunga neMold
Iinjineli ezininzi zikuthatha ukuphosa njengenyathelo “lokumila okurhabaxa”—into eyenziwe ngoomatshini kamva. Loo ngqondo iyasilela xa ubukhulu bodonga buguquguquka ± 0.8 mm ngaphaya kwesiseko sempompo yesanti engama-420 mm, okanye xa uxinzelelo olushiyekileyo olusuka ekupholiseni okungalinganiyo lugqwedisa umzimba wevalve yentsimbi engenasici emva komatshini wokugqibela. E-QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD., Siphatha ukuphosa njengomsebenzi wokuqala ochanekileyo-hayi owokugqibela. Indawo yethu yokuthobela i-ISO iqhuba utyalo-mali olunxuseneyo kunye nemigca yokugalela isanti, nganye ilinganiswe kwiintsapho ezithile zengxubevange: ialloys ye-cobalt-nickel efana ne-T800 kunye ne-AMS 5387 ifuna ukucotha, ukupholisa okulawulwayo; intsimbi ye-ductile ye-winch shafts yemoto yobunjineli ifuna ulawulo oluchanekileyo lwamaqhuqhuva egraphite; iicasts steel stainless ifuna ukugalelwa kwe-inert-atmosphere ukuze kugcinwe ukuxhathisa ukudleka.
Siqinisekisa ijometri yokungunda sisebenzisa ipateni yedijithali-hayi nje i-CAD-to-CAM inguqulelo. Kwindlu yesilinda yempompo yepiston, senza imodeli yokucutha kwe-thermal kuwo wonke amacandelo abalulekileyo ali-17, emva koko sihlengahlengise iiprinta eziphambili kunye nesango lokungena kwi-ID yonyamezelo ngaphakathi kwe-± 0.12 mm ngaphambi kokuba kuqale naluphi na umatshini. Yiloo ndlela esizisa ngayo ii-castings eziya ngqo kumatshini wokugqiba-akukho kuphinda kusebenze, akukho siphene, akukho siliphu seshedyuli.
Udibaniso oluthe nkqo: Apho ukuCasa Kudibaniswa neNyaniso yoMachining
Abanye ababoneleli bakhuphela ngaphandle, abanye benza oomatshini bangaphandle. Ayisebenzi kwiindawo apho imfezeko yomphezulu kunye nesambuku semicrostructure kufuneka silungelelaniswe. Iplagi yengxubevange ye-cobalt ayinzima nje-iqinile ukuba isithuba sengalo ye-dendrite singaphezulu kwe-25 µm. Kodwa ukwenza ubuchwephesha obugqithisileyo ukuleqa ukugqiba umphezulu kubeka imingcipheko ye-subsurface microcracks. Sisombulula oku ngokulawula iziphelo zombini: iqela lethu le-Foundry labelana ngedatha yohlalutyo lwexesha lokwenyani kunye nabadwelisi benkqubo be-CNC. Xa iziphumo ze-spectrographic zibonisa i-0.02% yekhabhoni ephezulu kwi-batch ye-T800, i-toolpath yethu ilungisa izinga lokutya kunye noxinzelelo lokupholisa-kungekhona nje ukukhusela i-insert, kodwa ukugcina uxinzelelo olushiyekileyo kwindawo egqityiweyo.
Oku kudityaniswa kunciphisa ixesha lokukhokela ngama-37% kwii-odolo zomthamo ophakathi. Okubaluleke ngakumbi, isusa ukukhukuliseka okuphakathi phakathi kokusa kunye nenxalenye yokugqibela. Silinganise ukuphindaphinda kwe-0.008 mm ukutenxa kwisithuba se-8-hole iipateni ze-flange kwiiyunithi ze-120-ngaphakathi kwesiqingatha semfuno ye-ASME Y14.5 MMB. Olo lungelelwaniso luvela kwi-metrology ekwabelwanayo ngayo: iCMM efanayo, ishedyuli efanayo yolungelelwaniso, iprotocol efanayo yokutolika kwe-GD&T kuyo yonke i-QA yokusa kunye nokwenza amaqela e-QA ngomatshini.
Material Traceability ukuba Ngokwenene umkhondo
“Izinto eziqinisekisiweyo” azithethi nto ukuba inombolo yobushushu kwisatifikethi sokusila ayihambelani neqashiso lokugalela, okanye ukuba isampulu yovavanyo lwebhara yokuqina ithe yatsalwa kwindawo yokugalela eyahlukileyo. Silandelela yonke ikhilogram yezinto eziluhlaza-ukusuka kwirisithi ye-ingot eqinisekisiweyo ye-T800 ngokunyibilika, ukugalelwa, unyango lobushushu, kunye nokuhlolwa kokugqibela. I-casting nganye ithwala i-tag ye-QR-coded edibanisa ukulandelelwa ngokupheleleyo: ukubunjwa kweekhemikhali nge-ASTM E353, ubukhulu beenkozo nge-ASTM E112, imephu yobunzima kuwo wonke amacandelo, kunye neengxelo ze-CMM kuzo zonke iimpawu ezibalulekileyo.
Kubathengi be-oyile kunye negesi abafuna ukuthotyelwa kwe-API 6A, sandisa ukulandelwa kuvavanyo olusebenzayo: yonke i-valve yoxinzelelo ifumana ubungqina be-hydrostatic kwi-1.5 × uxinzelelo olulinganisiweyo, kunye nokufundwa kwe-strain gauge efakwe kwicandelo ngalinye. Ukuba umthengi ubuza ukudinwa kubomi bompompo we-AMS 5387, sitsala eyona log yobushushu, siphinde sibale isantya sokuqina, kwaye sinxibelelane nemifanekiso ye-SEM yokwaphuka komphezulu ukusuka kwiibhetshi zokuqinisekisa kwangaphambili. Akukho ngqikelelo. Akukho extrapolation. Ubungqina nje.
Ukuchaneka kokwenyani kwehlabathi kuqala ngeeNgxoxo zokwenyani
Asithengisi iinkonzo zokuphosa-silungisa iindlela zokusilela. Xa i-OEM ye-hydraulics yaseYurophu ibika i-18% yokulahlwa kwizindlu ze-cylinder ngenxa ye-ovality ebomvu, asizange sicaphule isikhunta esitsha. Sityelele umgca wabo wokudityaniswa, silinganise ukwanda kwe-thermal yezixhobo zabo zokukhwelana, kwaye sayila ngokutsha ubume bembambo zokuphosa ukuchasana nokugqwetheka ngexesha lomjikelo wabo wokuhomba. Isiphumo: 99.2% isivuno sokuphumelela kokuqala, utshintsho lwero kwisixhobo sabo esikhoyo.
Lowo ngumahluko phakathi kwe umzi-mveliso weenkqubo zokuphosa ngokuchanekileyo kunye nesiseko. Yiyo loo nto abathengi baseMntla Melika, eJamani, naseSingapore besithumelela imizobo ye-GD&T-enzima hayi nje iiRFQs. Bayazi ukuba siya kuphawula imingcipheko yokwenziwa kokwenziwa kwezixhobo phambi kokuba kuqale isixhobo: i-0.005 mm yokufota okusicaba kumphezulu oyi-300 mm wesanti? Siza kucebisa utyalo mali endaweni yoko. I-nozzle ye-T800 ye-alloy engekho esemgangathweni kunye ne-radii yangaphakathi phantsi kwe-0.3 mm? Siza kulinganisa ukhukuliseko olubangelwa ukuhamba kwaye sicebise ngonyango lwe-HIP lwasekhaya.
Ndwendwela https://www.tsingtaocnc.com ukuphonononga izifundo eziqinisekisiweyo zobuchule benkqubo ye-cobalt alloy casting, ukukhuphela izikhokelo zokutolika kwe-GD&T, okanye ucele ukuphononongwa kwasimahla kokwenziwa kwemveliso kwicandelo lakho elilandelayo lokunyamezelana okuphezulu. Ukuchaneka akufezeki ngokuzimeleyo-kwakhiwe apho inzululwazi yokuphosa idibana noqeqesho lobuchwephesha, kwaye apho zonke iinkcukacha zinengcaciso ebonakalayo.
