Pamene mainjiniya amatchula a utumiki woponya kwa mavavu othamanga kwambiri a hydraulic kapena zigawo zapampu za cobalt-alloy, sikuti amangoyitanitsa zitsulo-akubetcha pamlingo wokhazikika pansi pa katundu wa 300-bar, kukhulupirika kwa microstructure pambuyo pa chithandizo cha kutentha, ndi zero batch-to-batch drift pakukana dzimbiri. Tawona makasitomala akuchedwetsa kutsimikizira kwa prototype pofika masabata 11-osati chifukwa cha zolakwika zamapangidwe, koma chifukwa mnzawo woponya sakanatha kunyamula ± 0.05 mm pa AMS 5387 nozzle bore. Imeneyo si nkhani ya makina. Ndi a utumiki woponya vuto lakukhwima.
Chifukwa Chake "Kupeza Maluso Odalirika" Ndi Fanizo Lolakwika - Ndipo Zomwe Zimagwira Ntchito
"Kupeza talente" kumapangidwa m'mafilimu, osati kufunafuna zinthu zamakampani. Poponyera mwatsatanetsatane, kudalirika kumatanthauza kukhazikika kokhazikika mu nkhungu zamchenga za T800 alloy housings, osati zomwe zapezeka. Zimatanthawuza kutsimikizira ingot iliyonse ya cobalt-nickel motsutsana ndi malipoti oyesa mphero musanathire - osadalira ziphaso za ogulitsa pamtengo wake. Zimatanthawuza kugwira kupatuka kwa 0.12% ya kaboni muzitsulo zomwe zikubwera zisanaduke munyumba ya silinda yapampu ya piston.
Tafufuza zinthu zopitilira 40 ku Asia ndi Eastern Europe kuyambira 2019. Kuphatikizika koyima—osati kokha “kuponya + makina,” koma kugawana kutanthauzira kwa GD&T pakati pa opanga mapangidwe ndi opanga mapulogalamu a CNC. Wokasitomala m'modzi adatumiza zojambula zofanana kwa ogulitsa atatu: awiri otchulidwa padera kuti apange ndi kumaliza-machining; yachitatu yomwe ili ndi mapu ofunikira kuchokera ku nkhungu kupita ku lipoti lomaliza la CMM. Wogulitsa yekhayo ndi amene adapereka zigawo zankhani yoyamba zomwe zidadutsa kuyesa kukakamiza kogwira ntchito tsiku loyamba.
Kumeneko sikupeza talente. Ndi ndondomeko umwini.
Zinayi Zosakambirana mu Mission-Critical Casting (Mothandizidwa ndi Real Failure Data)
Gulu lathu loyang'anira ntchito limatsata zomwe zimayambitsa zokanidwa pama projekiti 127 omwe akugwira ntchito. Mitundu inayi yolephera imalamulira-iliyonse yolumikizidwa mwachindunji ndi momwe a utumiki woponya imapanga ntchito yake:
- Microshrinkage m'matupi apamwamba a alloy valve: Zimachitika pamene ma gradient otentha amapitilira 12 ° C / mm panthawi yolimba. Kukhazikika kokha ndi kuyang'anira nthawi yeniyeni ya thermocouple muzitsulo za nkhungu-osati kuyang'anitsitsa pambuyo pa kutsanulira.
- GD&T imasuntha pakati pa ma as-cast ndi mayiko omaliza: Zomwe zimayambitsidwa ndi kusinthasintha kwamayendedwe ochepetsa nkhawa. Timayesa kupsinjika kotsalira kusanachitike komanso pambuyo pa annealing pogwiritsa ntchito XRD; makasitomala amene kudumpha izi onani 0.08-0.15 mm warpage pa 300-mm silinda nyumba.
- Kuphatikizira masango mu ma aloyi a cobalt: Kuyambitsidwa ndi kukokoloka kwa ladle refractory. Kutsimikiziridwa kudzera mu ASTM E45 Mtundu wa A kuphatikiza-osati macheke owoneka.
- Dimensional kubalalitsa mu zodzigudubuza za winch shaft zosakhazikika: Zotsatira kuchokera ku zosindikiza zapakati zosawerengeka. Kuthetsedwa kokha ndi kuwala kwa masanjidwe a core mabokosi pamaso pa kusintha kulikonse.
Palibe mwa izi ndi "nkhani zabwino". Iwo amapangidwa mu ndondomeko ya kulenga. Simungathe kuyang'ana njira yanu yotulukamo.
Ubwino Wophatikiza: Kumene Kuyimitsa Kuyima ndi Machining Kumayambira
Kuponya si sitepe yodziyimira yokha-ndi maziko a zomwe zikubwera. Thupi la valve loponderezedwa loponyedwa mu chitsulo cha ductile lingafunike 17 ntchito zosiyana za CNC: kubowola dzenje lakuya podutsa ndime zoyendetsa ndege, mphero ya contour ya malo osindikizira, ulusi wozungulira polumikizira ma torque apamwamba. Koma ngati makulidwe a khoma la as-cast amasiyana ndi ± 1.2 mm, moyo wa zida umatsika 40%, ndipo kutsirizika kwapamwamba pankhope zosindikiza kumakhala kosabwerezabwereza.
Ndicho chifukwa chake kudalirika kwenikweni kumafuna kulamulira kosakanizidwa. Pamalo athu a Qingdao, mainjiniya yemweyo amatsimikizira njira ya sera yoponyera ndalama komanso pulogalamu ya 5-axis Machining. Timagwiritsa ntchito data ya laser-scanned as-cast kuti tisinthe njira za zida-kudula nthawi yozungulira ndi 22% pazigawo zapampu za AMS 5387 pamene tikugwira Ra ≤0.4 µm pa malo ovuta kwambiri. Izi si zamatsenga zamapulogalamu. Ndi chilango chogwira ntchito: metallurgists amagawana mafayilo ofananitsa olimba ndi makina; Akatswiri a QC amayesa ma probe a CMM pogwiritsa ntchito ma gage omwe amagwiritsidwa ntchito powunikira.
Popanda kuzungulira kumeneko, mukuwongolera zoopsa ziwiri zosiyana-osati yankho limodzi lophatikizidwa.
Zomwe "Zodalirika" Zimatanthauza Pa Ntchito Yanu Yotsatira
Kudalirika sikungofuna kutsatsa. Ndizotheka kuyeza: 99.2% zokolola zoyamba pamilomo ya aloyi a cobalt, 100% kutsatiridwa kwa zinthu mpaka kutentha kwa nambala ndi chipika chosungunula, ndikutsatira pakadutsa masiku ± 3 pa 86% ya madongosolo apakatikati (deta ya 2023). Zikutanthauza kuti kujambula kwanu kumaphatikizapo ndemanga monga "Sungani datum B 0.3 mm mkati-izi zimapewa kusokoneza 0.1 mm ndi makina otsegula" m'malo mwa "Tiyesetsa momwe tingathere."
Ngati kuyitanitsa kwanu kudzakhudzanso kuponyedwa kwachitsulo kwamafuta ambiri, nyumba zazitsulo zosapanga dzimbiri zamapampu apansi pa nyanja, kapena zida zosagwirizana ndi T800 zomwe zimafunikira kutsata kwa ASME BPVC Gawo II, funsani utumiki woponya mafunso atatu: Kodi mungandiwonetse malipoti atatu omaliza a CMM a gawo lomwe likufanana ndi zomwe ndikulolera? Ndani yemwe ali ndi ndondomeko yokonza ndondomeko—ndipo kachitidwe kabokosi kamene kamatsimikiziridwa kangati? Kodi ndi liti pamene kufufuza kwanu kwamkati komaliza kumatsutsana ndi ISO 9001:2015 Ndime 8.5.1 (Kupanga ndi kupereka chithandizo)?
Mayankho ake adzakuuzani zambiri kuposa kabuku kalikonse.
