Mukamva 'kuyika ndalama moyenera', chithunzi chomwe chilipo nthawi zambiri chimakhala chopanda cholakwika, chokhala ndi mawonekedwe amlengalenga. Ndiwo malonda abwino. Zowona pansi, patatha zaka makumi atatu mumasewerawa, ndikukambirana kosalekeza pakati pa zabwinozo ndi fiziki yamakani yazitsulo zosungunuka ndi zipolopolo za ceramic. Makasitomala ambiri, makamaka omwe angoyamba kumene, amabwera ndi mitundu ya CAD akuyembekezera zozizwitsa - kulolerana kokulirapo kuposa nsidze ya udzudzu, monga momwe zimatayira pamwamba zimamaliza kupukuta, ndipo zonsezi pamtengo wolingana ndi masitampu opangidwa ndi anthu ambiri. Ndiko kukambirana koyamba komwe tili ku QSY: kukhazikitsanso ziyembekezo ku gawo la zomwe zingatheke mwakuthupi. Luso loona silimangopanga kuyimba; Ndi mu uinjiniya unyolo wonse wa ndondomeko—kuchokera pa patani ya sera kupita ku gawo lomalizidwa lopangidwa ndi makina—kuti zifike pokoma pakati pa kagwiridwe ka ntchito, mtengo wake, ndi kudalirika. Ndi mwambo wamba, osati matsenga.
Lingaliro Lolakwika: Kulondola Kumatanthauza Palibe Ntchito Pambuyo Kuponya
Tikhale osayankhula. Ngati gawolo ndi lovuta kwambiri, lokhala ndi ngalande zamkati, mafupi, kapena makoma owonda, mwatsatanetsatane ndalama kuponya ndizosavuta kupanga. Koma 'as-cast' pafupifupi 'sakonzeka-kukhazikitsa'. Kulondola kumatanthawuza kubwerezabwereza ndi kujambula mwatsatanetsatane, osati chiphaso chomaliza. Ndawonapo mawonekedwe okongola a turbine blade akulephera kuyang'ana chifukwa choyikapo choyikirapo chinachotsedwa ndi magawo atatu mwa magawo khumi a millimeter. Jekeseni wa sera anavala, pang'ono. Ichi ndichifukwa chake tidaphatikiza makina a CNC m'nyumba zaka makumi angapo zapitazo. Kuponyedwa kumakupatsani 95% pamenepo, mu geometry yolondola, ndi kukhulupirika kwakuthupi. Makina omaliza a CNC, nthawi zambiri pamakina a 5-axis, amakupatsirani miyeso yomaliza, yotsimikizika. Kuganiza za kuponya ndi kukonza ngati masitepe apadera ogulitsa ndi pomwe mapulojekiti amataya nthawi, ndalama, ndikuyambitsa zolakwika zakusanjikizana.
Kusankha kwakuthupi ndi theka lina la izi. Timagwira ntchito kwambiri ndi chitsulo chosapanga dzimbiri ndi ma aloyi opangidwa ndi nickel. Vuto lodziwika bwino ndikutchula alloy yogwira ntchito kwambiri ngati Inconel 718 chifukwa cha kutentha kwake, koma osawerengera kutsika kwake kwakukulu komanso kung'ambika kotentha panthawi yolimba. Mapangidwe ndi zipolopolo za 718 ndizosiyana kwambiri ndi 316 zosapanga dzimbiri. Simungangosintha zomwe zili mu pepala lokhazikika ndikuyembekeza kuti zomwezo zigwire ntchito. Twatela kwijiva ngwetu vatu vavavulu vali nakuzachila hamwe navyuma vyakupompa vize vyapwa vyavilemu chikuma. Yankho lake linali kuphatikizika kwa ma geting apadera kuti athe kuwongolera njira yolimba komanso kuwongolera kuzungulira kwa zipolopolo. Ndi maphikidwe azinthu zenizeni, omangidwa zaka 30, omwe amalekanitsa malo ogulitsa ntchito ndi akatswiri.
Zomwe zimandifikitsa ku mfundo zothandiza za zipolopolo. Njira ya 'kupanga nkhungu ya zipolopolo' yomwe timagwiritsa ntchito - kupanga zigawo za ceramic - ndipamene ntchito zambiri zimakhala. Chowonda kwambiri chipolopolo, ndipo mumatha kupuma, kulephera kosokoneza komanso koopsa. Chokhuthala kwambiri, ndipo mumataya kulondola kwake chifukwa chipolopolocho sichimatsika bwino ndi chitsulo chomwe chikucheperachepera. The slurry viscosity, stucco mchenga kukula kwa njere, kuyanika nthawi pakati pa malaya… ndi luso lomva ngati lasayansi. Katswiri wodziwa bwino ntchito yake amatha kuzindikira ndi phokoso la kugunda chigoba chouma ngati kuli bwino kupita. Ichi sichinthu chomwe mumangodzipangira nokha.
Kumene Njira Imawala (ndipo Pomwe Siima)
Kupambana kwachikale pakupanga ndalama ndizovuta-zolemera. Mabulaketi apamlengalenga, zida zachipatala, zida zogwirira ntchito zamadzimadzi zomwe zimakhala ndi manifold ophatikizika. Posachedwapa tinayendetsa pulojekiti yopangira nyumba ya sensor yomwe imayenera kukhala ya hermetic, mu 17-4PH yosapanga dzimbiri, yokhala ndi zopinga zamkati ndi ulusi wokwera kunja. Kuponya kunalola kuti zinthu zamkati zipangidwe, kupulumutsa kuchuluka kwa EDM kapena ntchito yowotcherera. Kenako tidapanga CNC-mawonekedwe osindikiza ndi ulusi kuti tifotokoze. Njira imodzi yoyenda, dongosolo limodzi labwino. Kuyesera kupanga izi kuchokera ku billet kukanakhala kokwera mtengo kwambiri.
Koma si za chirichonse. Nthawi zonse ndimachenjeza kuti ndisagwiritse ntchito ma geometries osavuta, achunky. Chida cholimba kapena choyambira choyambira? Ndibwino kuti muyambe kuponya mchenga kapena kuyambira pa bar stock ndi makina. Mtengo wa chitsanzo cha sera ndi chipolopolo umachepetsedwa pothamanga, kotero kwa ma prototypes kapena otsika kwambiri, mtengo wa unit ndi wapamwamba. The breakeven point imadalira kwambiri mapangidwe. Nthawi zina, mtengowo sukhala pamtengo weniweni koma pakuchepetsa nthawi yotsogolera pochotsa masitepe a msonkhano.
Mphepete mwa Integration: Kuchokera ku CAD kupita ku Crate
Izi ndi zomwe khwekhwe lathu la Qingdao Qiangsenyuan Technology Co., Ltd. (QSY) limamangidwa mozungulira. Kuphatikizika koyima sikungomveka; ndichofunika kulamulira. Wothandizira akatitumizira chitsanzo cha gulu la valve, gulu lathu la uinjiniya silimangoyang'ana gawolo. Timapanga gulu la sera (momwe zigawo zingapo zimalumikizidwa palimodzi pa 'mtengo'), kutsanzira kudzazidwa kwa nkhungu ndi kulimba kuti tidziwiretu kutsika kwa phula, kenako kukonza makina a CNC akugwira ntchito pamtundu womwewo wa digito. Injiniya yodzaza kutsogoloyi ndiyofunikira. Kuponyera kopangidwa mwaluso kumachepetsa kuchuluka kwa zitsulo zomwe zidzakambidwe pambuyo pake, ndikupulumutsa zida zonse komanso mtengo wazinthu, makamaka pamtengo wokwera. ma aloyi opangidwa ndi cobalt.
Ndikukumbukira kulephera komwe kunatiphunzitsa phunziro ili kosatha. Wofuna chithandizo anaumirira kuti agwiritse ntchito zida zawo zojambulira sera pamipando yambiri yam'madzi. Chidacho chinali chakale, mawonekedwe a sera anali ndi kusiyana pang'ono. Tidawaponya, kuwapanga makina, kenako tidapeza kusiyanasiyana kwa batch-to-batch makulidwe a khoma zomwe zidapangitsa ena kulephera kuyesa kukakamiza. Vutoli limachokera ku sera, kukulitsidwa mu chipolopolo, ndipo kunali kosatheka kukonza makina. Kuyambira pamenepo, timakonda kuwongolera, kapena kuwunika mozama, unyolo wonse. Webusaiti yathu, tsngtaocnc.com, ikufotokoza izi, koma umboni weniweni uli mu malipoti oyendera nkhani yoyamba yomwe timapanga.
Mbali ya makina sikungowonjezera. Kukonza pamwamba ndi kosiyana ndi kupanga billet yopangidwa. Khungu limatha kukhala ndi kuuma pang'ono pang'ono, ndipo kukonza kwake kumayenera kuwerengera nthawi zina-zosakhazikika zapadatum. Makina athu amazolowera izi. Amadziwa kutenga gawo loyamba kuti akhazikitse datum yowona kuchokera ku gawo la 'as-cast', lomwe ndi luso palokha.
Nuances Zakuthupi: Si Nambala Yagiredi Yokha
Kugwira ntchito ndi ma alloys apadera kumatanthauza kumvetsetsa khalidwe lawo kupitirira pepala la deta. Tengani faifi wopangidwa ndi aloyi kuti mugwiritse ntchito kutentha kwambiri. Magawo ake oponya ndi kuvina kolimba. Kuthira kotentha kwambiri, mumapeza kukula kwakukulu kwambewu ndikuchita kwa slag. Thirani ozizira kwambiri, mumapeza mistruns. The post-casting heat treatment ndi gawo la kuponyera, osati sitepe yosiyana. Pamagiredi opangitsa kuti mvula ikhale yolimba, njira yothetsera mavuto ndi kukalamba iyenera kupangidwa molingana ndi kapangidwe kake kuti akwaniritse zomwe zafotokozedwa m'gawo lonse, osati pamakuponi oyesera.
Timasunga zipika zatsatanetsatane za banja lililonse la alloy. Kutsanulira chipika cha mtanda wa duplex zitsulo zosapanga dzimbiri chidzazindikira ng'anjo yamoto, kutentha kwapampopi, ngakhalenso nyengo (chinyezi chimakhudza njira yochotsera chipolopolo). Kutsatiridwa uku sikungakambirane kwamakasitomala odzitchinjiriza komanso oyendetsa ndege, koma ndikuchita bwino pachilichonse. Imasintha luso kukhala njira yobwerezabwereza ya uinjiniya.
The Real-World Compromise ndi The Takeaway
Ndiye kodi akatswiri akuganiza bwanji apa? Precision Investment casting ndi chida champhamvu, koma si njira yodziyimira yokha. Mphamvu yake imatsegulidwa kwathunthu ikapangidwa ngati sitepe yoyamba muzotsatira zophatikizika zopanga. Cholinga sikukwaniritsa gawo langwiro monga-cast (ngakhale timayesetsa), koma kuti tikwaniritse njira yotsika mtengo komanso yodalirika yopita ku gawo lomaliza, lopanda ungwiro. Pamafunika mgwirizano wakuya pakati pa wopanga kasitomala ndi wopanga makina opanga kuyambira tsiku loyamba.
Zopambana zazikulu zomwe takhala nazo ndi pamene makasitomala amabwera kwa ife panthawi yamalingaliro. Titha kulangiza pa ngodya zolembera, makulidwe a khoma, ndikuphatikizana kuti gawolo lisamangoponyedwa, koma kuti likhale lopangidwa bwino. Nthawi zina izi zikutanthauza kuwonetsa kusintha pang'ono komwe kumapulumutsa 20% pamtengo wagawo popanda kutayika kwa magwiridwe antchito.
Pambuyo pa zaka 30, zomwe ndikuziwona ndizowonjezera mgwirizanowu, osati zochepa. Pamene zipangizo zikupita patsogolo kwambiri ndi mapangidwe ophatikizika kwambiri, mzere pakati pa kuponyera ndi makina umasokonekera. Malo ogulitsira a kampani ngati QSY ndiye mzerewu, wosawoneka bwino, woyendetsedwa bwino. Ndiko kumene kulondola kwenikweni kumabadwira—osati kokha mu nkhungu, koma mu kasamalidwe ka ulendo wonse kuchokera ku chitsulo chosungunula kupita ku gawo la m’bokosi, lokonzekera kugwiritsiridwa ntchito movuta. Ndizochepa chabe za masitepe ochititsa chidwi komanso zambiri zokhudzana ndi kusasinthika, zolembedwa pamasitepe mazana ambiri. Ndicho Choonadi chosadetsa cha izo.
