Mukamva Mtengo wa T400, chinthu choyamba chomwe anyamata ambiri ogula amachiganiza ndi cobalt alloy, kukana kwabwino, kuchitidwa. Ndiko kutengera kwapamwamba, ndipo moona mtima, ndipamene mashopu ambiri amapunthwa. Sizinthu zolemba; ndi khalidwe. Pazaka makumi atatu pakuponya ndi kukonza, ndawona kusiyana pakati pa lonjezo la database ndi zenizeni za sitolo ndi ma aloyi awa. Aliyense amalankhula za mphamvu zake zotentha kwambiri komanso kukana kwa dzimbiri, koma nkhani yeniyeni ili mu mapangidwe a chip, zida zobvala zida, ndi momwe zimayankhira njira zosiyanasiyana zozizira. Ndi zinthu zomwe zimafuna ulemu, osati kungogula.
The Foundry Floor Reality yokhala ndi Cobalt Alloys
Ntchito yathu ku Qingdao Qiangsenyuan Technology Co., Ltd. (QSY) nthawi zambiri imayamba kale makina a CNC asanayambe. Ndi zinthu ngati Mtengo wa T400, ndondomeko yoponya imayika maziko a chirichonse chotsatira. Timakonda kwambiri nkhungu za zipolopolo ndi kupanga ndalama pazifukwa zina - kukhazikika kwa mawonekedwe ndi kukhulupirika kwa pamwamba. Kuthira ma aloyi opangidwa ndi cobalt sikufanana ndi kuthira zosapanga dzimbiri. Pali matenthedwe osiyanasiyana, mawonekedwe olimba osiyana. Ngati chitseko kapena kukwera molakwika pa siteji iyi, mukungopanga zidutswa zodula kwambiri, zolimba kwambiri pambuyo pake. Ndawonapo magawo akutuluka mu nkhungu akuwoneka bwino, kungopangira makina kuti awulule subsurface porosity yomwe imapha chida mumasekondi. Kugwirizana pakati pa malo opangira makina athu ndi malo ogulitsira makina sikungakambirane pagululi.
Mutu umodzi wapadera wokhala ndi 400-series cobalt alloys ndi kulekanitsa kwa carbides. Popanga ndalama, mutha kupeza mbewu yabwino kwambiri, koma ngati kuzizira sikuyendetsedwa bwino, magulu olimba a carbides. Ndiye, mukapita kukachipanga, chodulira chanu sichikumana ndi zida zofananira. Zimakhudza timatumba tating'ono tating'ono tating'ono tating'ono tating'ono tomwe timayambitsa kuvala m'mbali mosayembekezereka. Izo sizimawonetsa pa lipoti loyesa kuuma, koma zimakuwirani pa chida chowunikira. Apa ndipamene zaka 30 zodziwika bwino zimadza - kudziwa kuwerenga kamangidwe kameneka ntchito yoyamba isanayambe.
Tinaphunzira izi movutikira pa ntchito yoyambirira yazamlengalenga. Zisindikizo zinafunika Mtengo wa T400, ndipo tidapeza aloyiyo, tidayiponya ku spec, ndikuyamba kupanga. Zigawo zingapo zoyamba zinali zabwino, koma moyo wa zida unakhala wosagwirizana kwambiri. Tidadzudzula zida, magawo, chilichonse. Titang'amba tsitsi lathu, tinabwereranso kumalo osokera ndi kusanthula zitsulo. Vutoli linali lopanga ma carbide mobisa, chifukwa cha kusagwirizana pang'ono ndi kutentha kwathu komwe timaloledwa. Kukonza sikunali mu pulogalamu yamakina; kunali kulimbitsa zowongolera zathu zoyambira kupitilira muyezo. Tsopano, pazigawo zofunika kwambiri, timawona ngati-cast microstructure ngati malo oyamba komanso ofunikira kwambiri owunikira.
CNC Machining: Kuvina kwa Parameters ndi Kuleza mtima
Chabwino, ndiye muli ndi kutulutsa mawu. Tsopano kuvina kwenikweni kumayamba. Machining Mtengo wa T400 ndipamene zakudya zongopeka ndi liwiro zimakumana ndi zenizeni zenizeni. Simungathe kungoponya choyikapo chokhazikika cha carbide ndikuyembekeza zabwino. Takhala ndi chipambano chosasinthika ndi magiredi odzipatulira a submicron carbide, nthawi zina kupita ku ceramic kapena CBN kuti amalize ma pass pamikhalidwe yovuta. Koma choyikapo ndi theka la nkhaniyo. Kukhazikika ndi chilichonse. Kulankhula kulikonse, kugwedezeka kulikonse, ndi zinthuzo zikuwoneka kuti zikugwira ntchito molimba mtima, zomwe zimapangitsa kulephera.
Cholakwika chachikulu chomwe ndikuwona ndi opanga mapulogalamu omwe amachitenga ngati Inconel ya super-alloy. Mphamvu zodula ndizosiyana. Ndi Mtengo wa T400, muyenera kukhala osasinthasintha, odulidwa bwino. Kubowola pobowola, mwachitsanzo, kumatha kukhala kovulaza ngati mutasiya chidacho kuti chisisite pansi pa dzenje. Zimapanga kutentha komweko komanso kulimba kwa ntchito zomwe zimatha kukumba motsatira. Tinasamukira ku kubowola zakudya zopatsa mphamvu mosalekeza pogwiritsa ntchito zida zapadera zoziziritsira, ndipo mitengo yosweka idatsika kwambiri. Ndizing'onozing'ono izi - mtundu womwe mumangophunzira pojambula zopangira $ 300 - zomwe zimapangitsa kusiyana pakati pa phindu ndi kutayika pa ntchito.
Kuziziritsa sikungozizira pano; ndi wothandizila zokometsera komanso wothandizana ndi chip-evacuation. Timayendetsa makina othamanga kwambiri, okwera kwambiri. Chip kuchokera Mtengo wa T400 ikhoza kukhala yolimba komanso yolimba. Ngati sichikuchotsa malo odulidwa nthawi yomweyo, imadulanso, kuwononga pamwamba ndikuyika chida. Nthawi ina tinali ndi mphero yakuya ya m'thumba momwe zonse zinali zangwiro poyerekezera. Pansi, tidamaliza moyipa komanso kuvala zida mwachangu. Nkhani yake? Kuponderezedwa kozizirirako sikunali kokwanira kutulutsa tchipisi pakona yakuzama. Kusintha kosavuta kwa hardware kukhala kukhazikitsidwa kwa nozzle-nozzle kulunjika kugawo lodulidwa kunathetsa. Phunziro: musaganize kuti malo opangira makinawa ndi achiwiri kunjira yazida.
Kusokoneza Zoyendetsedwa ndi Ntchito ndi Kusankha Zinthu
Chifukwa ngakhale ntchito Mtengo wa T400? Ndi okwera mtengo ndi ululu makina. Yankho nthawi zonse limakhala pazofuna za pulogalamuyo. Nthawi zambiri timapereka zida za mavavu amphamvu kwambiri, zida zovalira pampu, ndi zopangira zakuthambo. Zikatero, kuphatikiza kukana kukokoloka kwa dzimbiri ndi kukhalabe ndi mphamvu pakutentha kokwera kumapanga chisankho chokhacho. Koma Co T400 si monolith. The katundu yeniyeni akhoza kusintha kutengera kutentha mankhwala pambuyo kuponyera. Nthawi zina kasitomala amafunsa kuuma kwambiri, osazindikira kusinthanitsa kwa machinability komanso kukhudza kulimba.
Tidali ndi kasitomala akuumirira kulimba kwa Rockwell C pamwamba kwambiri pamtundu wa mbale yovala. Tidapanga makina, koma zokolola zake zinali zowopsa chifukwa chosweka pang'ono pomaliza. Tinaganiza zonyengerera: kulimba kocheperako pang'ono, koma ndi mankhwala enaake otentha kuti apange wosanjikiza wowuma, wosavala ndikusunga pachimake cholimba. Zinachita bwino m'munda ndipo zinali zotsika mtengo kwambiri kuzipanga. Ili ndi gawo la upangiri wa ntchito yathu ku QSY-osati kungosindikiza, koma kulangiza za kapangidwe kake kopanga ndi kothandiza kwambiri. Kutsatira mwachimbulimbuli mfundo zakuthupi osamvetsetsa chifukwa chake ndi njira yokhumudwitsa.
Izi zimandibweretsa ku mfundo yofananira: kukopa kwa zida zofanana. Mu magawo otsika mtengo, mainjiniya amatha kuyang'ana ma aloyi opangidwa ndi nickel kapena zitsulo zosapanga dzimbiri zolimba. Kwa ntchito zina, zitha kugwira ntchito. Koma kukana kowona kwa galling m'magawo okwerera, kapena malo okhala ndi sulfidation kapena phulusa lotentha, matrix opangidwa ndi cobalt Mtengo wa T400 ndi osiyana. Tayesa mayeso ofananirako amakasitomala, ndipo kusiyana kwa moyo wautumiki kungakhale kofunikira kwambiri. Si kukweza; ndi njira yeniyeni yothetsera vuto linalake.
Zolephera, Maphunziro, ndi Kuphatikizika kwa Njira
Simungachite bwino pa izi popanda zipsera. Chimodzi mwa zolephera zathu zophunzitsa chinali gulu la mipanda yovuta, yopyapyala yokhala ndi mipanda. Kujambula kunali kovuta koma kopambana. Pamakina a CNC pa mphero zathu za 5-axis, tidakumana ndi kusokonekera kowopsa pakumaliza komaliza. Tinathetsa nkhawa zonse zamkati mwa chithandizo chamankhwala, kapena momwe timaganizira. Nkhaniyi inali yotsalira yotsalira kuchokera ku makina opangira okha. Kudutsa movutitsa, kochitidwa ndi magawo aukali kuti tisunge nthawi, kudapangitsa kupsinjika kokwanira komwe tidatenga njira yomaliza kuti tipeze kulolerana, gawolo linaphuka.
Kukonzekera kunali kotsutsa: tinayenera kuchepetsa. Tinapanga njira yochepetsera masitepe ambiri ndi njira zochepetsera kupsinjika kwakanthawi (kugwedezeka kupsinjika, pakadali pano) pakati pa ntchito. Zinawonjezera nthawi yozungulira, koma zidapangitsa kuti ntchitoyi ikhale yodziwika bwino ndikuchotsa zotsalira. Izi zidasintha kwambiri njira yathu yopangira zida zamtengo wapatali, zovuta zochokera kuzinthu zovuta. Tsopano ndi gawo lathu lamayendedwe ofunikira Mtengo wa T400 zigawo. Mutha kupeza zina mwazanzeru zopambana izi zokhazikika munjira yomwe timalembera makasitomala patsamba lathu pa. https://www.tsingtaocnc.com.
Kuphunzira kwamtunduwu ndichifukwa chake ntchito yophatikizika yophatikizika ngati QSY ili ndi malire. Mayankho afupikitsa. Pamene makina ali ndi vuto, gulu la foundry lili pomwepo kuti likambirane za kapangidwe kake. Pamene foundry amayesa njira yatsopano, makina amamva zotsatira zake nthawi yomweyo. Kwa zinthu monga nuanced ngati Mtengo wa T400, kuphatikiza uku ndikwamtengo wapatali. Imasuntha kukambirana kuchoka pamlandu (kuponya kwanu kuli koyipa) kupita ku kuthetsa mavuto pamodzi (kodi timasintha bwanji kachitidwe ka geometry iyi?).
Kuyang'ana M'tsogolo: Osati Chinthu Chabe
Kupita patsogolo, kukambirana mozungulira zipangizo ngati Mtengo wa T400 ikusuntha. Sikuti kungogula mapaundi a aloyi. Ndi za kugula njira yopangidwa yomwe imaphatikizapo chidziwitso cha ndondomeko kuti ipange. Kupanga kowonjezera kumagogoda pazitseko za ena mwa mapulogalamuwa, koma chifukwa cha umphumphu, zigawo zazikulu, zoponyedwa zotsatiridwa ndi makina olondola a CNC akuperekabe kuphatikiza kosagonja kwa kuwongolera katundu ndi mtengo.
M'malire otsatira kwa ife ndi kuphatikiza kolimba kwambiri koyerekeza. Tikugwiritsa ntchito finite element analysis (FEA) kutengera momwe ma carbide amagawidwira, kenako ndikuyika datayo mu pulogalamu ya CAM kuti titha kusintha njira za zida potengera kusiyanasiyana kwazinthu zomwe zanenedweratu. Ndi masiku oyambilira, koma cholinga chake ndikuchoka pazovuta zothetsera mavuto kupita kuwongolera njira zolosera. Zakuthupi ndizokhazikika; kuthekera kwathu kumvetsetsa ndikuwongolera njira yozungulira ndikusintha komwe tikupitilizabe kugwira ntchito.
Kotero, pamene mukuyesa Mtengo wa T400 kwa projekiti, yang'anani kupyola pepala la data. Ganizirani za kumveka bwino kwa kuponyera, njira yopangira makina, kuyanjana kwa kutentha kwa kutentha, ndi mtengo wonse wa umwini, osati mtengo wamtengo wapatali pa kilogalamu imodzi. Ubwino uli pamizere pakati pa masitepe opangira, ndipo ndipamene zaka zambiri zokhazikika, monga zomwe tamanga ku Qingdao Qiangsenyuan, zimalipira. Ndiko kusiyana pakati pa gawo lomwe limakumana ndi spec ndi gawo lomwe limapulumuka m'munda.
