Pamene mainjiniya afotokoza mwatsatanetsatane kuponyera mbali wopanga fakitale m'makalata ogula, sikuti amangoyitanitsa zitsulo - amangofuna kubwereza mobwerezabwereza pansi pa 0.02 mm, kusasinthika kwa microstructure pamagulu otenthedwa ndi kutentha, ndi kudalirika kwa ntchito pambuyo pa maola 10,000 mu ma hydraulic valve manifolds kapena nyumba zapampu zakunyanja. Tawona mapulojekiti ambiri akuyimitsidwa chifukwa wogulitsa adagwiritsa ntchito cobalt-nickel alloy ngati "ntchito ina yachitsulo." Si.
Chifukwa Chake Makhalidwe Akuthupi Amakakamiza Mapangidwe - Osati Njira Ina Yozungulira
Ma aloyi opangidwa ndi cobalt ngati AMS 5387 kapena T800 samapangidwa ngati chitsulo chosapanga dzimbiri. Mlingo wawo woumitsa ntchito umakwera pambuyo pa 0.1 mm wakuya kwakuya. Kutentha kwawo ndi theka la 304 zosapanga dzimbiri - kotero moyo wa chida umatsika 60% ngati kuzizira kwa mpweya kugwera pansi pa 70 bar. Mu shopu yathu, sitiyamba ndi mapulogalamu a CNC. Timayamba ndi mapepala azitsulo: kugawa kukula kwa tirigu kuchokera ku maziko, mapu a carbide precipitation annealing post-solution annealing, ndi ma curve okhazikika m'chipinda chonse ndi 400 ° C. Pokhapokha m'pamene timatsekera liwiro la spindle, chakudya pa dzino, ndi stepover.
Chilango ichi chimalekanitsa kutulutsa kolondola kwenikweni ndi mawu apamtunda. Pampu imodzi yaku North America OEM idatitumizira chojambula cha nyumba ya silinda ya pisitoni-yolimba GD&T pa concentricity (Ø0.015 mm), malo osindikizira ovuta kwambiri mpaka Ra 0.4 µm, ndi kuuma kofunikira kwa 38–42 HRC ukakalamba. Ogulitsa awo akale ankagwiritsa ntchito mchenga wa generic + kumaliza makina. Zotsatira zake? 37% ya zinyalala chifukwa cha subsurface porosity pafupi ndi nsonga yothamanga kwambiri. Tinasintha kuponya ndalama ndi kuthira kothandizidwa ndi vacuum, kuonjezera kuyesa kwa akupanga musanayambe kupanga makina, ndikugwirizanitsa kupanikizika pakati pa mabala ovuta ndi omaliza. Zokolola zidalumpha mpaka 94%. Gawolo linadutsa mayeso a hydrostatic pa 1.5 × ovotera kuthamanga-palibe kutayikira, palibe kupotoza.
Magulu Anayi a Zogulitsa-Aliyense Amamangidwa Chifukwa Cholephera-Umboni Wogwira Ntchito
Timangoyang'ana pazigawo zomwe kulephera kumabweretsa zotsatira zantchito kapena chitetezo. Palibe zokongoletsera. Palibe mabatani olekerera pang'ono. Basi mission-critical metal:
- Zigawo zamakina za CNC: Mipikisano yozungulira ya mapulagi olimba a cobalt ndi ma nozzles, ndikuyesa kuyesa kutsimikizira makulidwe a khoma mkati mwa ± 0.05 mm pazigawo za 2-mm-zoonda
- Cobalt-nickel alloy zigawo: Zigawo zapampu za AMS 5387 zopangidwa kuchokera ku certified T800 billet, zokhala ndi batch traceability kubwerera ku chipika chosungunuka ndi satifiketi ya ESR remelt
- Kuponyedwa kwachitsulo: ASTM A48 Kalasi 35 Maziko a pampu yachitsulo imvi-opangidwira kugwetsa kugwedezeka, osati katundu wokhazikika
- Chitsulo & zitsulo zosapanga dzimbiri: AISI 4140 ndi 17-4PH nyumba zopangira makina opangira ma winch center shaft rollers, otenthedwa kuti agwirizane ndi moyo wotopa.
Chilichonse chimatumiza ndi lipoti la mayeso azinthu (MTR), lipoti loyang'ana mozama lomwe lasainidwa ndi wovomerezeka wa CMM, ndi chipika chowoneka bwino cholembedwa ndi ISO 13919-1 wovomerezeka wovomerezeka - ngakhale palibe kuwotcherera komwe kumachitika. Chifukwa chiyani? Chifukwa makasitomala amatiuza owerengera awo tsopano akufuna kwa ogulitsa mafuta a Tier 1.
Ubwino Siuwunikiridwa M'kati - Umapangidwira, Pang'onopang'ono
Mafakitale ena amayendera komaliza pazigawo zomalizidwa. Timayendera malo asanu osayanjanitsika:
- Kutsimikizira kwazinthu zopangira: Kusanthula kwa Spectrometric + kuyesa kochuluka kwa akupanga pa coil / billet iliyonse musanadule
- As-cast geometry: Optical contour scanner imayang'ana ma angles owongolera ndikusintha kwapakati musanatenthetse
- Mapu akuuma kwa kutentha kwapambuyo: 9-point Rockwell C grid pamadera ovuta, osati malo amodzi okha
- M'ntchito CMM: Pambuyo roughing, asanamalize, kutsimikizira stock allowance amakhalabe yunifolomu
- Kutsimikiziridwa kogwira ntchito: Ma valve opanikizika omwe amayesedwa pa 1.3 × ntchito yogwira ntchito; ma winch shafts spin-balanced to G2.5 per ISO 1940-1
Timasunga ma rekodi a digito kwa zaka 10, osati chifukwa choti malamulo amafunikira, koma chifukwa kasitomala adapezapo kulephera kwa mapulagi a cobalt a 2019. Njira yathu yotsatirira imawalola kudzipatula ndikulowetsa mayunitsi 147 okha - osati 5,000.
Kudalirika Kumayamba Ndi Momwe Mumayankhulira-Chip Choyamba Chisawuluke
Chomwe chimayendetsa mtengo kwambiri pakuponya molondola sizinthu kapena ntchito. Ndi kukonzanso koyambitsidwa ndi ziyembekezo zolakwika. Chifukwa chake timayika kuwunika kwauinjiniya mu gawo la mawu - osati mwaulemu, koma ngati chipata cholimba. Wogula akapereka chithunzi cha gulu losakhazikika la valve, gulu lathu limayika zinthu zitatu mkati mwa maola 48:
- Ma callouts a GD&T omwe amasemphana ndi zofunikira pakuponya (mwachitsanzo, kutchula 0° pakhoma loyima la 300-mm)
- Kumapeto kwapamwamba sikutheka kutheka popanda kugaya kwachiwiri (Ra 0.8 µm pamalo oponyedwa mchenga amafunika +$12/kg)
- Zolemba zakuthupi zomwe zimanyalanyaza kusagwirizana kwa kukula kwa matenthedwe-monga kulumikiza mpando wa valavu ya cobalt ndi thupi lachitsulo cha kaboni mumayendedwe a nthunzi
Sitikunena kuti "inde" pazopempha zilizonse. Timati "izi ndi zomwe zimagwira ntchito, chifukwa chake, ndipo nayi mtengo wanjira iliyonse." Kuwonekera kumeneku kumachepetsa nthawi ya NRE ndi 40% pafupifupi - ndipo kumapangitsa kudalirana mwachangu kuposa baji iliyonse yotsimikizira.
Kwa akatswiri ofufuza mwatsatanetsatane kuponyera mbali wopanga fakitale abwenzi, kudalirika sikufuna malonda. Ndi zoyezera: ≤0.8% PPM scrap rate pa cobalt components, ≤72-hour lead time for prototype castings, and zero late delivery to European OEMs mu 2023. Ikusankha wogulitsa amene amasamalira zojambula zanu osati ngati fomu yoyitanitsa-koma monga kudzipereka kwaumisiri wogawana. Umu ndi momwe magawo ofunikira amapezera malo m'makina omwe nthawi yopuma imawononga $ 28,000 / ola.
