Pamene mainjiniya amatchula a zitsulo nkhungu kuponyera fakitale pazigawo zamafakitale zolondola, sikuti amangopanga ma castings-akusankha mnzake waukadaulo yemwe amatha kupirira ± 0.02 mm pamilomo ya cobalt alloy, kusunga umphumphu wa microstructure pambuyo pochiza kutentha, ndikupereka zida za AMS 5387 zomwe zimapulumuka 15,000 psi hydraulic hydraulic hydraulic. Ndicho chenicheni cha ntchito-osati malonda ogulitsa.
Chifukwa Chake “Kuponya Nkhungu” Sikumveka (ndi Chifukwa Chiyani Kuli Kofunika)
Ogula ambiri amaganiza kuti "kuponyera chitsulo" kumatanthawuza kungoponyera kapena nkhungu zokhazikika. Pochita, kulondola kwenikweni kumafuna kusinthasintha: kuponya mchenga kwa maziko akulu a pampu omwe amafunikira chitsulo chochepetsera kupsinjika; kuponya ndalama kwa mapulagi a T800 cobalt alloy okhala ndi mipanda yozizirira mkati; ndi njira zosakanizidwa pomwe zojambulidwa zamtundu wamtundu wa ukonde zimayendera makina a CNC amitundu isanu kuti akwaniritse ma data a GD&T. Tawona makasitomala akukana mawu ochokera kumafakitale omwe akupereka njira imodzi yokha-kenako amakumana ndi 40% zotsalira pomwe nyumba yawo ya silinda ya pisitoni idasokonekera pomaliza kutentha. Kukonzekera sikunali bwino kuponyera-kunali kugwirizana kolimba pakati pazitsulo zazitsulo ndi ndondomeko zotsitsimula pambuyo poponyedwa.
Mphamvu Zinayi Zosakambirana Zomwe Simungathe Kuzipereka
A odalirika zitsulo nkhungu kuponyera fakitale Ayenera kuwongolera madera anayi awa mkati-osati kudzera mu subcontracting, koma kudzera mumayendedwe ophatikizika:
- Kufufuza Kwazinthu Kufikira Ku Nambala Yotentha: Gulu lililonse la AMS 5387 cobalt alloy alloy limabwera ndi malipoti ovomerezeka a mphero. Timatsimikizira zomwe zili ndi kaboni, kukula kwa mbewu, komanso kukana kwa dzimbiri kwapakati tisanathire - ngakhale zitachedwetsa kupanga ndi maola 36.
- Chilango cha Kuponya-Machining Handoff: Akatswiri athu amakasitomala amalandila ma "machining allowances" odziwika potengera kuchucha kwenikweni - osati ma chart amtundu uliwonse. Kwa wodzigudubuza wa winch center shaft, izi zikutanthauza kusiya 1.8 mm pa OD m'malo mwa 2.5 mm, kuchepetsa nthawi yozungulira ndi 22% popanda kupereka nsembe yomaliza.
- Kuyang'anira Ntchito - Osati Macheke a Dimensional: Nyumba ya valve yopanikizika imadutsa kuyendera kwa CMM koma imalephera kuyesa ntchito ngati porosity yamkati imasokoneza kayendedwe kake. Timayesa kuyesa kwa helium pa 3 × kukakamiza kugwira ntchito ndikutsimikizira roughness pamwamba (Ra ≤ 0.4 µm) pa nkhope zosindikiza pogwiritsa ntchito stylus profilometers-osati kuyerekezera kwa kuwala.
- GD&T Literacy Yophatikizidwa mu Kuwunika Kwaukadaulo: Wogula akapereka chojambula chokhala ndi malo olekerera pamtunda wosagwiritsidwa ntchito ndi makina, timayimilira-osati ngati kukana, koma ndi njira zina zothetsera mavuto: kuwonjezera gawo lachiwiri la datum, kusintha ma angles okonzekera, kapena kufotokoza sitepe yopera yomwe imasunga ndalama.
Mtengo weniweni wa "Standard" Castings mu Critical Application
Ogula ena amathamangitsa mtengo wotsika kwambiri - ndiye amalipira kuwirikiza katatu pakulephera kwamunda. Zida zamafuta aku North America OEM nthawi ina zidapanga maziko a pampu yachitsulo chosapanga dzimbiri kuchokera kwa ogulitsa otsika mtengo. M'miyezi 18, 17% adawonetsa kung'amba pang'ono pamalumikizidwe a flange. Choyambitsa? Kusiyanitsa kosalamulirika kwa silicon panthawi yolimba, yophimbidwa ndi mayeso olimba koma kulephera kutsimikizika kwa moyo wa kutopa. Yankho lathu: kuziziritsa koyendetsedwa bwino + ASTM A957-yogwirizana yolimba yofananira pa kutsanulira kulikonse. Zotsatira: kulephera kwa zero kudutsa magawo 42,000 omwe atumizidwa kumadera akum'mwera chakum'mawa kwa Asia okhala ndi mchere wambiri.
Izi sizokhudza "kuponya bwino." Ndizokhudza kumvetsetsa momwe kutentha kwachitsulo ku eutectic kusinthira kuzizira kofulumira kumakhudzira kuwerengera kwa ma graphite nodule - komanso chifukwa chomwe zimakhudzira kugwedezeka kwamphamvu mu injini zama hydraulic manifolds.
Zomwe Muyenera Kufunsa Musanavomereze Mtundu Woyamba
Osafunsa "Kodi mungapange gawo ili?" M'malo mwake funsani mafunso asanu awa:
- Kodi kupatuka kwanu kovomerezeka ndi kotani pakati pa zonenedweratu ndi kuchepa kwenikweni kwa geometry iyi ndi aloyi?
- Ndiwonetseni malipoti anu atatu omaliza a Cpk okhazikika pamapampu ofanana.
- Kodi mumatsimikizira bwanji kuti pali zinthu zofanana *mutatha* kupanga—makina asanayambe?
- Ndi zowongolera ziti za ng'anjo yotenthetsera yomwe imakhala nthawi mkati mwa mphindi ± 1.5, ndipo kufanana konyowa kumatsimikiziridwa bwanji?
- Kodi mungapereke kutsatiridwa kwathunthu - kuphatikiza chipika chosungunuka, kutentha kwa kuthirira, ndi piritsi yozizirira - pazigawo zilizonse zotumizidwa?
Ngati mayankho alibe chindunji, chokanipo. Kulondola sikutheka pakuwunika komaliza - kumatsekeredwa mkati mwa sekondi yoyamba yolimba.
Kuyang'ana M'tsogolo: Komwe Kuyimba Mwaluso Kukulowera
Malire otsatirawa si makina akuluakulu kapena maulendo othamanga. Ndilo zolosera zam'tsogolo: kuyika ma thermocouples mu nkhungu kuti musinthe kuzirala mu nthawi yeniyeni, pogwiritsa ntchito kusanthula kwa X-ray koyendetsedwa ndi AI kuti muwone zolakwika zapansi panthaka musanapange makina, ndikutsimikizira magawo osakanizidwa opangidwa ndi ASME BPVC Gawo VIII Div. 2 miyezo. Ku QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD., tikutsimikizira njira yatsopano yopangira aloyi ya T800 ya cobalt pomwe mawonekedwe ang'onoang'ono amatsimikiziridwa kudzera pamapu amtundu wa EBSD-osati zitsulo zamanja. Kuwongolera kumeneku kumasintha zomwe "chofunikira kwambiri" chimatanthauzanso.
Kusankha a zitsulo nkhungu kuponyera fakitale ikusankha yemwe ali ndi chiopsezo pamene makina anu a hydraulic akugwira ntchito pa 200 ° C ndi 12,000 psi. Othandizana nawo oyenerera samangokumana ndi zotsimikizika - amayembekeza mitundu yolephera yomwe simunapangebe. Izo sizikupanga. Ndi ntchito ya engineering.
