Mukamva 'kuponya ndalama mwachangu', ambiri amaganiza kuti ndi kungomenya 'mwachangu' panjira yakale yotayika. Ndilo mbuna yoyamba. Kuthamanga koona kuno sikungokhudza nthawi yozungulira; ndikuganiziranso mwadongosolo kupanga mapangidwe, kukhetsa zipolopolo, ndi kukhetsa mawakisi, zonse zikugwirabe kukhulupirika komwe kumapangitsa kuponya ndalama kukhala kofunikira. Mashopu ambiri amadzinenera, koma kusiyana pakati pa kupempha ndi kutumiza ndi kumene ntchito yeniyeni-ndi zolephera zosangalatsa-zimachitika.
Lingaliro Lolakwika: Kuthamanga motsutsana ndi Umphumphu
Cholakwika chachikulu chomwe ndikuwona ndikungoganiza kuti mutha kungofulumizitsa njira yachikhalidwe. Simungathe. Kuthira ndalama mu osindikiza othamanga a 3D pamapatani ndi chinthu chimodzi, koma ngati ndondomeko yanu yomanga chipolopolo siyingapitirire, kapena kutenthedwa kwanu kumakhala kosakhazikika, mwangopanga chopinga chodula kwambiri. Gawo la 'mwachangu' liyenera kukonzedwa mugawo lililonse, ndipo uinjiniyawo siwongokambirana. Ndilo lolingana, lokhazikika nthawi zonse, pakati pa kutenthetsa kwatsopano kwa slurry formulations ndi mphamvu zamakina zomwe zimafunikira pogwira.
Mwachitsanzo, tidayesapo kugwiritsa ntchito njira yatsopano yochiritsika ndi UV yomwe idalonjeza kuchepetsedwa ndi 60% munthawi yopanga mapangidwe. Liwiro linali lenileni. Vutoli lidawonekera panthawi ya autoclave dewaxing. Kukula kosiyanasiyana kwa matenthedwe kuyerekeza ndi sera yathu yokhazikika kunapangitsa ming'alu yaying'ono pajasi lotayirira, zomwe zidapangitsa kulephera kwa zipolopolo za 40% pamgulu woyamba woyeserera. Ndiwo mtundu wa 'mwachangu' womwe umatengera nthawi ndi ndalama zambiri. Zinatikakamiza kubwerera ku labu kuti tiwongolere kuchuluka kwa slurry's refractoriness ndi binder ratio makamaka pazinthu zatsopanozi. Yankho silinali lonse; chinali chokonzekera chokongoletsedwa.
Apa ndi pamene chidziwitso chogwira ntchito kwa nthawi yayitali chimakhala chofunikira. Kampani ngati Malingaliro a kampani Qingdao Qiangsenyuan Technology Co., Ltd., ndi maziko awo a zaka 30 chipolopolo nkhungu kuponyera ndi kuponya ndalama, mwachiwonekere wawona kusintha kwatsopano ndi kutsika uku. Chikumbukiro cha chikhalidwe cha momwe zida zimakhalira ndi kupsinjika ndizomwe zimalepheretsa kuthamangira munjira iliyonse yatsopano 'yofulumira'. Mutha kupeza zambiri za njira yawo patsamba lawo, tsngtaocnc.com. Kukhazikika kwawo pazitsulo zotayira mpaka kuzitsulo zopangira faifi kumasonyeza kuti amamvetsetsa kuti magawo 'ofulumira' achitsulo chosapanga dzimbiri sangagwire ntchito pa aloyi wopangidwa ndi cobalt. Ndiwo nuance.
Kusintha Kwachitsanzo: Kupitilira Kusindikiza kwa 3D
Inde, kusindikiza kwa 3D, makamaka stereolithography (SLA) kapena binder jetting, ndiye khomo la anthu ambiri kuti azitha kujambula mwachangu. Koma kuchitira mawonekedwe osindikizidwa ngati choloweza mmalo mwa sera ndi cholakwika cha rookie. Mapeto a pamwamba, phulusa pambuyo pakutopa, ndi ma polima otsalira onse amalumikizana ndi chipolopolo cha ceramic mosiyana. Nthawi zambiri mumafunika zokutira zachiwiri kapena kuviika koyambirira kosinthidwa kuti musindikize pamwamba. Tidaphunzira kugwiritsa ntchito magulu ang'onoang'ono otsimikizira - nthawi zina zipolopolo khumi ndi ziwiri - kuyimba pakupanga zinthu zatsopano kapena geometry tisanayambe kupanga.
Kupita patsogolo kwenikweni 'kofulumira', m'malingaliro mwanga, kuli mu njira zosakanizidwa. Pogwiritsa ntchito kusindikiza kwa 3D kupanga mapangidwe apamwamba a zida za silikoni, komwe mutha kubayapo sera angapo kapena makope osungunuka. Izi zimatsekereza kusiyana pakati pa liwiro lachiwonetsero chimodzi ndi kufunikira kwa kaphatikizidwe kamagulu ang'onoang'ono. Ndizosawoneka bwino kuposa momwe zimagwirira ntchito pa digito, koma nthawi zambiri zimakhala zodalirika komanso zotsika mtengo pakuthamanga kwa zidutswa 20-50.
Ndikukumbukira pulojekiti yopangira gawo la turbine zitsulo pomwe kasitomala amafunikira ma prototypes 30 ogwira ntchito poyesa injini. Zithunzi zosindikizidwa za 3D zikadakhala zokwera mtengo kwambiri. Tinasindikiza ukadaulo, kupanga nkhungu yotembenuza urethane mwachangu, ndikubaya jekeseni wa aloyi wosungunuka. Zinawonjezera mlungu umodzi kutsogolo koma zinapulumutsa pafupifupi milungu itatu pagawo lililonse la nthawi yosindikizira ndipo zinatipatsa makhalidwe ogwirizana kwambiri omanga zipolopolo. Zipolopolozo zinagwidwa, kuponyedwa kunali komveka, ndipo kasitomala adapeza mndandanda wawo wa mayeso panthawi yake. Ndiko kuponya ndalama mwachangu.
Kumanga Zipolopolo: Gawo Lopanga-kapena-Kusweka
Apa ndipamene ndondomekoyi imapeza chidaliro kapena kugwa. Kuyanika kofulumira kumakopa—kugwiritsira ntchito mpweya woumirizidwa, zochotsera chinyezi, kapena ngakhale kutentha pang’ono. Koma thamangitsani, ndipo mumatchera chinyezi kapena kupanga zomangira zofooka pakati pa malaya. Chigobacho chikhoza kuwoneka bwino mpaka chikafika pa ng'anjo, kenako chimalephera kwambiri. Tasamukira kuzipinda zoyendetsedwa bwino ndi chilengedwe zokhala ndi chinyezi chambiri komanso zowunikira kutentha. Zikumveka ngati zofunikira, koma kuwongolera uku kumatithandiza kufupikitsa nthawi zowumitsa malaya ndi 20-30% popanda kusokoneza kukhulupirika. Sizowoneka bwino, koma ndizothandiza.
Kusankha kwa stucco - mchenga wosasunthika womwe umayikidwa pakati pa slurry dips - ndi njira ina yobisika. Chipatso chokulirapo, chochulukirapo chimatha kupanga makulidwe a chipolopolo mwachangu, kuchepetsa kuchuluka kwa malaya ofunikira pa makulidwe operekedwa. Koma imathanso kupangitsa kuti pakhale mkati movutikira kwambiri pakuponya. Kumbali ina yomwe ikufuna kutsirizika kwabwino, mutha kumamatira ndi stuko bwino ndikuvomera malaya ambiri. Palibe chakudya chamasana chaulere; chisankho chilichonse chopulumutsa nthawi chimakhala ndi kusinthanitsa pamalingaliro ena.
Kwa ma aloyi ovuta, monga zitsulo zopangidwa ndi nickel QSY imagwira ntchito, chemistry ya chipolopolo palokha ndiyofunika kwambiri. Chigobacho chiyenera kupirira kutentha kwambiri kuthirira popanda kulimbana ndi chitsulo chosungunuka. Njira 'yofulumira' yomwe imagwiritsa ntchito chipolopolo chokhazikika cha chitsulo cha carbon chidzalephera ndi superalloy. Chigobacho chikhoza kufewetsa kapena kupanga inclusions. Choncho, njira 'yofulumira' iyenera kukhala yosiyana ndi aloyi. Kugwira ntchito kwawo kwanthawi yayitali muzitsulo zapadera, monga tafotokozera m'mbiri yamakampani awo, kumatanthauza kuti adayenera kupanga (ndipo mwina kuteteza) makina a zipolopolo zazinthu izi.
Kuwotcha ndi Kutentha Kwambiri: Thermal Gauntlet
Ichi ndi sitepe yochititsa chidwi kwambiri. Kuwotcha kwachikale kwa nthunzi kumagwira ntchito koma kumatha kuchedwerapo pamapangidwe okhuthala. Kuwotcha kwa Flash mu ng'anjo yotentha kwambiri kumathamanga koma kumapangitsa kuti chipolopolocho chiwotche kwambiri. Tinali ndi zipolopolo zomwe zimaphulika pamene sera inakula mofulumira kwambiri. Kugwirizana komwe takhazikikapo ndi njira ya magawo awiri: kachitidwe kakang'ono, kocheperako kamene kamachotsa sera, kutsatiridwa ndi kutentha kwa ng'anjo yoyendetsedwa kuti athetse zotsalira ndi sinter chipolopolo. Si njira imodzi yachangu kwambiri, koma imapereka chigoba chapamwamba kwambiri chopulumuka pamitundu yovuta.
Kutopa ndi malo ena okonzeka kukhathamiritsa. Cholinga ndikuchotsa zotsalira zonse popanda kutsindika kwambiri ceramic. Ma thermocouples oyikidwa mkati mwa zipolopolo za dummy amathandizira kupanga mapu a kutentha. Posanthula deta iyi, tatha kupanga magawo okwera mofulumira m'madera otentha momwe chipolopolo chimakhala chokhazikika, ndikuchepetsera pang'onopang'ono m'magawo ovuta kwambiri. Inameta pafupifupi 25% kuchotsera nthawi yathu yonse ya ng'anjo. Ndi mtundu wa 'wachangu' woyendetsedwa ndi data, osati kungoganiza.
Kulephera apa ndikokwera mtengo. Chigoba chong'ambika chomwe chapezeka pambuyo potopa kumatanthauza kuti mwataya nthawi zonse ndipo mtengo wake wayikidwa mpaka pano - chitsanzo, slurry, ntchito, mphamvu. Ichi ndichifukwa chake malingaliro a 'mwachangu' amayenera kuphatikiza kutsimikizira kwamphamvu. Mumafulumizitsa masitepe omwe mungathe kuwongolera ndikuyeza, ndipo mumasiya ma buffer pomwe zoopsa zimakhala zazikulu.
Kuphatikiza Machining: The Critical Finish
Kuthamangitsa ndalama mwachangu sikuchitika pamene gawolo likugwedezeka mu chipolopolo. Chikhalidwe cha as-cast pafupifupi nthawi zonse chimafuna zina CNC makina-kubowola, mphero zovuta nkhope, ulusi. Apa ndipamene unyolo wa 'mwachangu' ungadukenso ngati kuponya sikunapangidwe kuti apange manufacturability (DFM) kuyambira pachiyambi. Ngati musunga milungu iwiri pakupanga koma ndikufunika milungu itatu ya makina ovuta, ophatikizika ndi ma axis ambiri chifukwa cha malo ocheperako kapena zinthu zomwe sizingafikike, mwaluza mpikisano.
Kugwirizana pakati pa oyambitsa ndi makina ogulitsa ndikofunikira. Pa ntchito yophatikizika ngati QSY, pomwe kuponyera ndi CNC makina zili pansi pa denga limodzi, cholumikizira ichi chiyenera kukhala chopanda msoko. Amatha kupanga njira yopangira makina opangira makina, kuwonjezera masheya ochepa m'malo oyenera, ndikuwonetsetsa kuti makina a alloy amaganiziridwa. Mwachitsanzo, kalasi inayake ya chitsulo chosapanga dzimbiri zitha kuponyedwa mokongola koma kukhala zowopsa pamakina ngati chithandizo cha kutentha sichikuyendetsedwa bwino pambuyo poponya. Wothandizira wophatikizika amathandizira izi.
Mapulojekiti opambana kwambiri omwe ndakhala nawo nthawi zonse amakhudza akatswiri pamakina oyambira. Angaloze kusintha pang'ono komwe kungapangitse kuti pakhale chosavuta, kapena anganene kuti asunthire chingwe chodulira kuti apange datum yoyeretsa. Zokambirana izi, zomwe zikuchitika kutsogolo, ndizomwe zimapanga mapaipi onse - kuchokera ku digito mpaka kumapeto, gawo lopangidwa ndi makina - mwachangu komanso modalirika.
Kutsiliza: Ndi Filosofi, Osati Batani
Kotero, pambuyo pa zonsezi, ndi chiyani kuponya mwachangu ndalama? Siukadaulo umodzi womwe mumagula. Ndi nzeru za kukhathamiritsa kwa njira zophatikizika, mothandizidwa ndi chidziwitso chakuya komanso kufunitsitsa kuyesa zoyeserera (ndikuvomereza zolephera zina). Ndiko kudziwa komwe mungakankhire komanso komwe muyenera kudekha. Ndiko kusiyana pakati pa shopu yomwe imangopanga ma castings ndi yomwe imapereka mayankho opangidwa mwaluso panthawi yamavuto.
Makampani omwe amachita izi bwino, omwe ali ndi mbiri yakale pamitundu yosiyanasiyana monga chitsulo chachitsulo ndi ma aloyi apadera, apeza liwiro lawo. Iwo amanga izo kupyolera mu zodzikundikira, nthawi zina zowawa,. Iwo aphunzira kuti kufulumira kwenikweni ndiko kuchepetsa nthawi yotsogolera ku gawo logwira ntchito, loyenerera, osati pafupifupi maola omwe chitsulo chimathera mu nkhungu. Ndicho cholinga chenicheni, ndipo ndi chovuta kwambiri—ndipo chosangalatsa—kuposa momwe zimamvekera.
