Ulimi wamakono sukuyendanso mwachidziwitso chokha. Imayendera pazigawo zolondola - ma valve opanikizika omwe amakhala ndi mipiringidzo 350 popanda kutayikira, nyumba zapampu za piston zomangika mpaka ± 0.01 mm kulolerana, zodzigudubuza za winch center shaft zomwe zimapangidwira kuti zithetse grit yadothi yowononga kwa maola 12,000+ ogwirira ntchito. Zigawozi zikalephera, nthawi yocheperako siyiyezedwa m'mphindi - imayesedwa mu maekala otayika, mazenera okolola amasowa, ndikuwonongeka kwamafuta.
Ichi ndichifukwa chake vuto lenileni la ntchito zamafakitole zamakina si kuchuluka kwamunda kapena kulondola kwa GPS. Ndizitsulo zobisika kumbuyo kwa zida zachitsulo zofunika kwambiri: zomwe zimakwiriridwa mkati mwa ma hydraulic manifolds, zoyikidwa pansi pa ma axles a thirakitala, kapena zosindikizidwa mkati mwa mapampu amthirira othamanga kwambiri. Tawona minda ku Saskatchewan ikuchedwa kubzala chifukwa chopukutira chimodzi cha cobalt-alloy chinang'ambika pansi pa njinga yamoto. Tidawona mabungwe akummwera chakum'mawa kwa mpunga aku Asia akutaya zobowola mbeu pambuyo poti maziko a pampu osakhazikika adaphwanyidwa panthawi ya kutentha. Izi si "kulephera kwa makina." Ndizolakwika zakuthupi-ndi-njira-zothetsedwa osati ndi mathirakitala akuluakulu, koma ndi kupanga chigawo chanzeru.
Chifukwa Chake Precision Metal Parts Imatanthauzira Kulima Mwachangu
Zipangizo zamafamu zimagwira ntchito mopitilira muyeso: zoyambira pansi paziro ku Alberta, kutentha kwa 50°C ku Andalusia, kugwedezeka kosalekeza paminda yolemera dongo ku Brazil. Standard castings amasweka. Zitsulo zakunja zimakokoloka. Magawo a Generic CNC alibe umphumphu wa microstructural wofunikira pakukana kutopa pamizere 10,000.
Zopindulitsa zenizeni padziko lapansi zimachokera ku zofunikira zinayi zophatikizika:
- Dimensional bata-palibe kugwedezeka pambuyo pa chithandizo cha kutentha kapena kutsegula kwa hydraulic kwa nthawi yayitali
- Kusasinthika kwazitsulo-Kubwereza kwa batch-to-batch mu kuuma, kapangidwe ka tirigu, ndi kukana dzimbiri
- Geometry yogwira ntchito-njira zoyenda mkati zokhala ndi roughness pamwamba Ra ≤ 0.8 µm, malo osindikizira athyathyathya mkati mwa 0.005 mm
- Traceable process control-Zidziwitso zathunthu, Malipoti a CMM pagawo lililonse, kutsimikizika kwa GD&T musanadulidwe koyamba
Mafakitale ambiri amamakina opangira zaulimi amatulutsa kunja kapena kupanga makina - koma nthawi zambiri onse awiri. Kusiyana kumeneku kumayambitsa zolakwika: kuponya mchenga kumachepa mosayembekezereka panthawi yozizirira, ndiye kuti sitolo ya CNC imalipira kuchotsa katundu komwe kumafooketsa magawo ovuta a khoma. Chotsatira? Gawo lomwe limadutsa cheke koma limalephera kuyesa kuphulika kwa 80% kukakamiza kapangidwe.
Ubwino Wophatikizidwa: Kuponya, Kukonza, Kumaliza Pansi Pa Denga Limodzi
Ena amatsutsa kuti ukatswiri umapambana kuphatikiza koyima. Koma nyumba yanu ya pampu ya piston ikakumana ndi ma AMS 5387 cobalt alloy specs * ndi * kupulumuka mizere yokakamiza ya 200 miliyoni, kugawa ntchito pakati pa ogulitsa atatu kumachulukitsa chiwopsezo - osati kuchita bwino.
Tatsata ma prototype 47 a ma OEM aulimi a Tier-1. Mapulojekiti adakwanitsa kumapeto mpaka kumapeto-kuchokera pakupanga ndalama kudzera mumitundu yambiri ya CNC, chithandizo cha kutentha, ndi kusuntha-adapereka 63% zochepa zosintha zaumisiri ndikugunda zolinga zokolola koyamba 91% ya nthawiyo. Omwe amayendetsedwa m'malo osiyanasiyana oyambira ndi malo ogulitsira makina amakhala pafupifupi 3.2 loops pagawo lililonse labanja.
Izi sizokhudza kumasuka. Zimakhudza kuwongolera koyendetsedwa ndi fizikisi:
- Magawo oponya amadziwitsa mwachindunji kukonza makina - palibe zongoyerekeza pakusintha kwakukulu kapena kuchepetsedwa.
- Njira zochiritsira zotenthetsera zimayikidwa nthawi kuti zigwirizane ndi makina otsatirawa, kuteteza kupsinjika kotsalira.
- Kumaliza pamwamba (mwachitsanzo, electropolishing kwa matupi amadzimadzi osapanga dzimbiri) kumayamba * asanaunike komaliza - kotero kuti zolakwika sizimabisa zolakwika zapansi panthaka.
Makasitomala m'modzi - wopanga makina opopera odzipangira okha ku Europe - amadula ma hydraulic valve m'malo mwa 40% atasintha kuchoka pazitsulo zachitsulo kupita ku nyumba za T800 zokhala ndi cobalt zokhala ndi makina ophatikizika ochepetsa kupsinjika. Zolemba zawo zosungirako zidawonetsa kulephera kwa ziro zosindikizira m'miyezi 18 - motsutsana ndi zochitika 7 zomwe zidachitika chaka chatha.
Zomwe Zimafunika Pakusankha Zinthu (Kupitilira "Zitsulo Zosapanga dzimbiri")
"Chitsulo chosapanga dzimbiri" sichitanthauza kanthu popanda nkhani. AISI 304 imawononga kwambiri njira za ammonium nitrate. ASTM A536 ductile iron imataya mphamvu yopitilira 120 ° C. Komabe magulu ogula zinthu amatchulabe "zopanda banga" pa RFQs-ndipo amalipira kuti agwiritsenso ntchito pamene zina zimalowa m'matangi a feteleza.
Zochitika zenizeni padziko lapansi zimatengera zisankho zitatu:
- Gulu la aloyi likufanana ndi kulephera: Cobalt-nickel alloys (monga AMS 5387) kwa kukokoloka-kudzimbirira mu mapampu slurry; zitsulo zosapanga dzimbiri za ferritic zotsutsa kloride m'makina othirira m'mphepete mwa nyanja
- Njira yopangira imagwirizana ndi geometry: Kuponyera ndalama kwa matupi a valve opyapyala okhala ndi mizere yamkati; kuponyera mchenga kwa maziko akulu a pampu ofunikira kugwedera
- Kutsimikizira pambuyo pa ndondomeko kumangiriridwa ndi ntchito: Kuyesedwa kwa utsi wa mchere *pambuyo pa * passivation - osati kale; kuyendera kwa ultrasonic * pagawo lililonse *, osati nkhani yoyamba
Posachedwapa tathandiza wopanga zida zogwiritsira ntchito tirigu ku US m'malo mwa shaft yolephera ya carbon-steel auger drive. Wogulitsa wawo wakale adagwira mawu "chitsulo cholimba kwambiri." Ndemanga yathu yazitsulo idawonetsa kulephera kwawo kwenikweni kunali kupangidwa kwa haidrojeni kuchokera ku zokutira kosayenera. Tidasinthira ku 4140 yokhazikika ndikuwotcha kwa haidrojeni-ndikuwonjezera moyo wautumiki kuchokera pa miyezi inayi mpaka miyezi 22 tikugwira ntchito mosalekeza.
Kusankha Wothandizirana Naye: Yang'anani Zikalata Zakale, Yang'anani Mayendedwe Antchito
ISO 9001 ndi magawo a tebulo. Chomwe chimalekanitsa ogulitsa odalirika ndi momwe amachitira ndi kusamveka bwino. Kodi amafunsa chifukwa chiyani kulekerera kuli kolimba - kapena kungobwereza mawu? Kodi angayimire mikangano ya GD&T asanadule zitsulo? Kodi amasunga manambala a kutentha kwazinthu zilizonse zomwe zimatumizidwa?
Ku QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD., dongosolo lililonse lokhudza zaulimi limayambitsa kuwunikiranso koyenera kwa zopanga. Timajambula mbali iliyonse kuti igwire ntchito yake: kulolerana kwa 0.02 mm pa dzenje lokwera sikopanda pake-kumalepheretsa kuvala molakwika molakwika mu mzere wa 200-hp PTO. Ngati chojambula sichikunena zimenezo, tikupempha. Ngati zofananira zikusemphana ndi kuthekera koponya, timapereka njira zina zochirikizidwa ndi data ya FEA-osati malingaliro.
Chilango chimenecho chikuwonetsa popereka: 98.3% kumaliza nthawi yake yopanga ma volume apakati (50-500 pcs/lot), ndikutsatiridwa kwathunthu mpaka pagulu la ng'anjo ndi mtundu wa pulogalamu ya CMM. Ayi "atsala pang'ono kukonzekera." Palibe "kutengera nthawi yotsogolera zinthu." Zongolembedwa, zobwerezabwereza.
Kuchita bwino kwaulimi sikumangika m'munda. Amapangidwa m'makina oyambira, amagayidwa m'maselo a CNC, ndikutsimikiziridwa mu labotale ya metrology - kale mbewu yoyamba isanamenye nthaka. Fakitale yamakina yaulimi yomwe imachita bwino izi sikuti imangotumiza magawo. Zimatumiza kuneneratu.
