Xa iinjineli zichaza iqokobhe lokubumba umzimveliso wokugalela iinkonzo zezixhobo zetsimbi eziphezulu, azithengi nje inkqubo-zikhusela ukuphindaphinda kwe-dimensional, ulawulo lwe-microstructural, kunye nokuthembeka komsebenzi phantsi koxinzelelo. E-QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD., Siphose phezu kwe-12,000 yezindlu zempompo ye-cobalt-alloy ukususela ngo-2019-nganye ibambe ± 0.05 mm ukunyamezela kwe-GD & T kwi-800 ° C yobushushu benkonzo. Ayingobuchule bethiyori leyo. Yiloo nto eyenzekayo xa ukubunjwa kweqokobhe kungaphathwa njengenyathelo elizimeleyo-kodwa njengesenzo sokuqala kulandelelwano oludityanisiweyo lonyango lobushushu.
Kutheni ukubumba iqokobhe kuzisa apho ukubunjwa kwesanti kusihla kufutshane
Ukubumba iqokobhe ayisiyondlela nje yokuphosa. Kuphela kwenkqubo ekufutshane-nomnatha-imilo ehlala ihambisa umphezulu ogqityiweyo ngaphantsi kwe-Ra 3.2 µm *kunye* kunye nokuhambelana kwesinyithi kuwo wonke amacandelo anodonga olubhityileyo phantsi kwe-6 mm. Sibona oku imihla ngemihla: umzimba we-valve ye-hydraulic ene-3.8 mm ubukhulu bodonga, i-12 iziteshi zokupholisa zangaphakathi, kunye ne-AMS 5387 cobalt alloy chemistry. Ukuchithwa kwesanti akuphumeleli apha-kungekhona kwindleko, kodwa kumngcipheko wokubandakanywa kwe-oxide kunye nokutshintsha okungundoqo ngexesha lokugalela. Ukubumba iqokobhe zisombulula zombini. I-phenolic resin-bonded silica sand shell ibeka ngokungqongqo kwi-230 ° C, ibamba i-geometry nge-1,420 ° C yokuthulula amaqondo okushisa, kwaye iyatshisa ngokucocekileyo-ishiya i-zero intsalela kwiindlela ezihamba phambili ezibalulekileyo.
Siyilinganisile: i-shell-moulded T800 alloy parts ibonisa i-22% ye-porosity ephantsi kuneendawo ezilinganayo zesanti-ezingqinisiswe yi-CT scanning ye-industrial phambi komatshini. Oko kuguqulela ngokuthe ngqo kubomi bokudinwa. Omnye umxhasi wesixhobo sendawo yeoli yaseMntla Melika wandisa amaxesha enkonzo yempompo yezindlu ukusuka kwi-4,200 ukuya kwi-7,800 yeeyure zokusebenza emva kokutshintshela kwizindlu zethu ze-cylinder ezibunjiweyo. Akukho tshintsho loyilo. Ngcono nje ukuqalisa imathiriyeli.
Ukudityaniswa okuthe nkqo akusiyo i-Buzzword-Lukunciphisa umngcipheko wakho
Abanye ababoneleli banikezela ngeesanti ezibunjwe ngoqokobhe koomatshini bomntu wesithathu. Asazi. Yonke inxalenye ye-cobalt-nickel isuka kumgca wokubumba weqokobhe oqinisekisiweyo we-ISO 9001 ukuya ngqo kwiiseli zethu ze-5-axis ze-CNC-akukho mpahla yangaphandle, akukho ukungaqiniseki okuphinda kubambezeleke, akukho kuhambelana kwembali ye-thermal ye-batch-to-batch. Oko kuqhubela phambili kubaluleke kakhulu kwiindawo ezifana ne-piston pump center shaft rollers: zenziwe zaqina ukuya kwi-HRC 58–62 *emva* komatshini, kungekhona ngaphambili. Ukuba unyango lobushushu lwenzekile phambi komatshini, uxinezeleko olushiyekileyo lunokujija i-0.015 mm yonyamezelo lwendawo yokwenyani kwijenali. Ulandelelwano lwethu luyayiphepha loo nto ngokupheleleyo.
Silandelela yonke into: iingxelo zovavanyo lokusila, iqokobhe lomjikelezo wokunyanga, ukugalela amajiko obushushu, iziphumo zokuhlolwa kwe-ultrasonic post-cast, kunye neengxelo zokugqibela zeCMM-zonke zidityaniswe kwideshibhodi enye yokulandeleka. Xa iOEM yaseYurophu icela umnombo wezinto ezipheleleyo kwi-AMS 5387 iodolo yombhobho, siye sazisa amaxwebhu asayiniweyo ali-17 kwiiyure ezingama-48. Akunjalo ngenxa yokuba sigcina amaphepha-kodwa ngenxa yokuba idatha ihamba ukusuka kwinzwa ukuya kwisistim ngexesha langempela.
Imida Yehlabathi Lokwenyani-Nendlela Esisebenza Ngayo Ngaphakathi Kuyo
Ukubumba iqokobhe kunemida. Iyasokola ngamalungu angaphezulu kwe-50 kg okanye iijiyometri ezifuna ii-undercuts ezinzulu kuno-15° ngaphandle kweecores eziqengqelekayo. Abanye banokuphikisa ukuphoswa kotyalo-mali kuphatha ezo zingcono. Kodwa ukuchithwa kotyalo-mali akukwazi ukuhambelana ne-throughput yethu kwi-middle-volume runs (50-500 pcs / inyanga) ye-steel castings eyinkimbinkimbi-ingakumbi xa abathengi bafuna uvavanyo olusebenzayo kwiinqununu zokuqala ze-3. Umgca wokubumba weqokobhe lethu uqhuba iiyure ezingama-22/ngosuku, utshintsha isixhobo esingaphantsi kwemizuzu eli-18, kwaye uqinisekisa ijiyometri yomgodi nge-laser scanning phambi kokugalelwa kokuqala.
Sikwayiphepha imigibe eqhelekileyo: ukusebenzisa isanti ehlaziyiweyo kwimixube yeqokobhe (sifumana isilica entsha exutyiweyo), ukutsiba ubushushu bangaphambili kwizinto ezinkulu zentsimbi (sinyusa izinga lokushisa kwi-45°C / ngeyure ukunqanda ukothuka kwe-thermal), okanye ukutsiba isiqabu sasemva kokuphoswa koxinzelelo kwizindlu ezingenastainless (sibamba ku-620°C kangangeeyure ezi-4, emva koko sibe yi-air-cool). Ezi ayizo "izenzo ezilungileyo." Zingamanyathelo angenakuxoxisana abhakwe kwimiyalelo yethu yomsebenzi-kuba siye sabona iintanda zefom xa kukho nabani na oye watsitywa.
Oko Ukufumanayo Ngokwenene—Asikuko Okuthenjisiweyo Kwincwadana
Ufumana uzinzo lwe-dimensional: i-shell-molded steel castings ebanjwe ukuya ku-±0.12 mm kwiimpawu ukuya kwi-320 mm ubude, iqinisekiswe nge-Zeiss CONTURA G2 CMMs ilinganiswe ngeveki. Ufumana uqikelelo lwe-metallurgical: yonke ibhetshi ye-T800 ye-alloy evavanyelwe i-cobalt, i-chromium, i-tungsten, kunye nomxholo wekhabhoni-ngaphakathi kwe-± 0.03% ye-spec-usebenzisa i-OES spectrometry. Ufumana uqeqesho lokuhambisa: I-94.7% yezinga lexesha lee-odolo zeprototype, i-98.2% yokukhutshwa kwemveliso-ilandelwa ngeedashboard ze-ERP eziphilayo ezabelwana ngazo nabathengi.
Kwaye ufumana intsebenziswano yobunjineli-ungacaphuli. Xa umenzi wempompo waseMzantsi-mpuma Asia wasithumelela umzobo one-0.005 mm flatness callout kwi-280 mm × 180 mm iflange yokunyuka, asizange sithi “ewe” okanye “hayi.” Siqhube imodeli ye-thermal distortion, sacebisa uyilo olulungisiweyo lwe-gating, kwaye sacebisa ukwenza i-flange *emva kokunciphisa uxinzelelo-hayi ngaphambili. Isiphumo? Izinga lokupasa kwenqaku lokuqala litsibe ukusuka kuma-62% ukuya kuma-99%. Lowo ngumahluko phakathi komthengisi kunye nokwandiswa kobugcisa beqela lakho.
Ukuba ufuna i iqokobhe lokubumba umzimveliso wokugalela ephatha ukuchaneka njengefiziksi-hayi ukuthengisa-sikulungele ukuqhuba iqashiso lakho elilandelayo. Hayi ngezithembiso. Ngamaphepha enkqubo, iingxelo zokuhlola, kunye nedatha ye-dimensional ukusuka kwisiqwenga sokuqala.
