Xa iinjineli zichaza a ilahleko yentsimbi yokugalela umzi-mveliso, abakhangeli nje isinyithi esigalelwe kumngundo. Bafuna uzinzo lwe-dimensional phantsi kwe-300 MPa hydraulic pressure. Ukulawulwa kweMicrostructure kwi-AMS 5387 cobalt alloy emva kokunyanga ubushushu. I-Zero porosity kwi-120-mm-diameter pump cylinder housing ejikeleza kwi-1,800 RPM ngelixa itywina ngokuchasene ne-abrasive slurry. Leyo yinyani yokusebenza-hayi isihloko sedatha.
QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD. isebenza enye into enjalo-i-ISO-certified, idityaniswe ngokuthe nkqo, kwaye yakhiwe malunga neendlela ezisebenzayo zokusilela. Siphose imilomo esekwe kwi-T800 kwiimpompo zokutofa ngaphandle konxweme apho isiphene somphezulu esiyi-0.05 mm sibangela ukhukuliseko oluyintlekele. Siye sasebenza ngomatshini izindlu zempompo zepiston ezine-GD&T callouts ziqina kune ± 0.015 mm kwiibhore zokutywina ezibalulekileyo-kwaye sanikezela imvume yenqaku lokuqala kwiinkqubo ezintathu ezilandelelanayo ze-OEM zaseMntla Melika. Oku ayingobuchule bethiyori. Kuyaphinda-phinda ukwenziwa phantsi kwemiqobo yelizwe lokwenyani.
Kutheni ilahleko yokuphosa i-wax yensimbi ingaphumeleli-ngaphandle kokuba ulawula ezi zixhobo ezine
Uninzi lweentsilelo zilandela kwesinye sezikhewu ezine: ukungangqinelani kwezinto, ukugqwethwa kwepateni, ilahleko yengqibelelo yeqokobhe, okanye ukungahambelani kobushushu ngexesha lokuqina. Abaseki abasemgangathweni badla ngokuphatha oku njengamanyathelo azimeleyo. Kwiziko lethu leQingdao, zizinto ezahlukeneyo ezinxibeleleneyo.
- Ukulandeleka kwezinto kuqala ngaphambi kokunyibilika: Yonke i-AMS 5387 okanye i-F22 ingot engenastainless ithwala iingxelo zovavanyo lokusila kwaye iphinde iqinisekiswe nge-OES spectroscopy xa ifunyenwe. Siyazikhaba iibhetshi ezine->0.02% yokutenxa isulfure-nokuba ingaphakathi kwimida ye-ASTM A995-kuba ihambelana ngokuthe ngqo nokukrazula okutshisayo kwimizimba yevalvu ebhityileyo.
- Ipateni yejometri ibanjwe ukuya ku-±0.03 mm: Sisebenzisa i-CNC-machined aluminium masters-kungekhona i-3D-printed resins-kwiipateni zotyalo-mali ezisetyenziswa kwimveliso ephezulu. Ngoba? I-resin shrinkage iyahluka ngokufuma kunye nexesha emva kokunyanga; aluminiyam ayikho. Omnye umxhasi we-hydraulic waseYurophu unciphise izinga lokulahlwa kovavanyo lokuvuza ukusuka kwi-4.2% ukuya kwi-0.3% emva kokutshintshela kwinkqubo yethu yepateni.
- Amandla eqokobhe kuyalinganiswa—akucingelwa: Inkqubo yethu ye-ceramic ye-ceramic dip-and-stucco ibandakanya ukujonga i-viscosity kwi-slurries kunye nohlalutyo oluzenzekelayo lwesayizi ye-stucco. Oonokrwece bayomiswa iiyure ezingama-24 ngendlela elawulwa ngumbethe ngaphambi kokuba badinwe. Ukutsiba eli nyathelo kubangela iintanda ezincinci ezithi zibe yi-subsurface voids kwi-X-reyi yokugqibela.
- Ukuqiniswa komfuziselo kuqhuba uyilo lokungena: Siqhuba ukulinganisa kwe-MAGMAsoft kuyo yonke into entsha yokuphosa intsimbi-ingakumbi kumabakala angenasici njenge-CF8M apho ulwahlulo lwe-dendritic luchaphazela ukuxhathisa ukubola. Iisistim zokungena zilungiselelwe kungekuphela nje ixesha lokuzalisa, kodwa ukuqinisa umkhombandlela ukuya kwizinyusi. Yileyo ndlela esifezekisa ngayo isandi kwiziseko zempompo ze-85-mm ngaphandle kwe-HIPing yesibini.
Apho umatshini udibana nokuphosa: inzuzo yomxube
Ukulahlwa kwewax elahlekileyo kukodwa akusombululi ingxaki. Kananjalo umatshini weCNC awukwenzi. Ukuchaneka kokwenyani kuza apho badibana khona-kwaye kulapho udibaniso oluthe nkqo luzisa i-ROI enokulinganiswa.
Sijula imizimba yevalvu yentsimbi engatyiwayo ene-2.5 mm yezibonelelo zokwenza ubuso obutywiniweyo, emva koko siyigqibe koomatshini be-5-axis DMG Mori abaxhotyiswe ngeRenishaw PH10M probes. Iidayamitha ezibalulekileyo ziqinisekisiwe phakathi kwenkqubo usebenzisa i-CMM ye-touch-trigger ilinganiswe kwi-ISO 10360-2. Isiphumo? Ukufundwa kwesalathisi ngokupheleleyo kuhlala ngaphantsi kwe-0.008 mm kubude be-150 mm ubude-ngaphandle kokugaya. Omnye umenzi wempompo waseMzantsi-mpuma Asia unqumle ixesha labo lokukhokela nge-37% ngokuhlanganisa ukuphosa kunye nokugqiba oomatshini kunye nathi endaweni yokulawula ababoneleli ababini.
Oku akukho malunga nokulula. Imalunga nokuphelisa impazamo yokupakisha. Xa umboneleli wakho wokusasa ene-±0.3 mm kwaye ivenkile yakho yomatshini ino ±0.1 mm, eyona meko imbi kakhulu yokunyamezela ijometri iba ±0.4 mm. Sibamba zombini iinkqubo phantsi kophahla olunye-kwaye silawula ukuhanjiswa kwedatum phakathi kwabo. Yiyo loo nto iivalvu zethu zoxinzelelo zidibana ne-API 6D yokuvuza iKlasi A ngaphandle kokuqengqeleka okwesibini.
Yintoni abathengi abayifunayo ngokwenene-kwaye yintoni abayifunayo ngokwenene
“Uyakwazi ukuphosa intsimbi engatyiwayo? kunqabile ukuba ibe ngumbuzo ochanekileyo. Ezenyani ziza mva:
- "Ngaba le ndlu ye-316L izakugcina amandla esivuno ngaphezu kwe-425 ° C emva kokuphosa + isisombululo sesisombululo?" → Ewe-kunye neerekhodi ezigcweleyo zonyango lobushushu kunye nedatha yovavanyo lwe-tensile ngebhetshi nganye ye-ASTM A370 eqinisekisiweyo.
- "Ngaba ungabamba i-0.005 mm flatness kwi-300 × 200 mm yeflange?" → Kuphela ukuba siyayimatshini emva kokuphoswa. Utyalo mali lulodwa aluyi kuzisa loo nto. Siza kukuxelela ngaphambili-kwaye sibonise uyilo lolungiso olwenza ukuba kwenzeke.
- "Ngaba uyayixhasa iNqanaba lesi-3 lePPAP?" → Ewe, kubandakanywa neengxelo zomda kunye ne-CMM point cloud, ii-cert zemathiriyeli, kunye nokuqhuba ii-FMEAs. Kodwa sikwabonisa ukuba zeziphi iimpawu ze-GD&T ezingazinzanga kwiqashiso lokuqala-kwaye sicebisa ezinye iindlela zolawulo.
Asithengisi "i-wax elahlekileyo yokuphosa intsimbi." Sithengisa isiqinisekiso esisebenzayo kwiinxalenye ezimele ziphile iiyure ezingama-20,000 kwinkonzo ye-oyile okanye iminyaka eli-15 kwiinkqubo zokwenziwa kwamanzi olwandle. Oko kufuna ukwala i-7.3% yesitokhwe esiluhlaza se-cobalt-nickel-hayi ngenxa yokuba iyasilela, kodwa ngenxa yokuba ubungakanani bayo bengqolowa buwela ngaphandle kwefestile yethu eqinisekisiweyo.
Ukukhetha umzi-mveliso wakho olahlekileyo wokuphosa intsimbi kuthetha ukukhetha iprofayile yakho yomngcipheko
Isicatshulwa esinexabiso eliphantsi sikhangeleka sinomtsalane de i-winch centre shaft yakho iqhekezeke ngexesha lovavanyo lomthwalo. Kuze kube yilapho iplagi yakho ye-cobalt ixutywe emva kweeyure ze-400 zokusebenza-kungekhona i-5,000 echaziweyo. Ide idimensional drift inyanzelise ukusebenza ngokutsha kwi-22% yeeseti zempompo ezidityanisiweyo.
Umahluko ulele kulawulo lwenkqubo ebhaliweyo—hayi amabango okuthengisa. Ekuqinisekisweni kwezinto eziphathekayo ngaphambi kokuthulula-kungekhona emva. Kwi-GD&T-aware casting design—hayi nje i-CAD translation. Kwiiprothokholi zokuhlola ezibotshelelwe kwiindlela zokungaphumeleli-hayi izintlu zokukhangela eziqhelekileyo.
QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD. yakha olo qeqesho kuyo yonke indlela. Hayi njengesongezo. Hayi njengokhetho. Njengesiseko.
Ukuba isicelo sakho sifuna iindawo ezichanekileyo zentsimbi apho ukusebenza kungaxoxiswana khona-apho "isondele ngokwaneleyo" ithetha ukulahlwa, ukulibaziseka, okanye umngcipheko wokhuseleko-udinga ngaphezu kwe-Foundry. Udinga iqabane eliphatha yonke into edlalwa ngathi iya kusebenza ngaphakathi kwimodyuli yolawulo lwangaphantsi kolwandle kubunzulu be-3,000 yeemitha. Nguwo lowo umgangatho wenjineli. Kungenxa yoko le nto iinjineli zibuyela-kaninzi kwaye kwakhona-kwi-a ilahleko yentsimbi yokugalela umzi-mveliso elilinganisa impumelelo kwintsilelo kwintsimi engu-0, hayi nje unikezelo ngexesha.
