Tiyeni tikambirane za chitsanzo cha mchenga kuponyera. Awa ndi amodzi mwamawu omwe amabwera nthawi zambiri, nthawi zambiri amakhala ndi kusamvetsetsana pang'ono. Anthu amamva ma prototype ndikuganiza za kusindikiza kwa 3D kapena makina othamanga kwambiri, chinthu chowoneka bwino komanso cha digito. Kenako amamva kuponyedwa kwa mchenga ndi kujambula kwakukulu, kupanga kosalala kumayendera midadada ya injini. Matsenga enieni, ndi vuto lenileni, zimachitika pomwe malingaliro awiriwa amakumana. Sikuti kupanga chidutswa chimodzi changwiro mu labu; ndi kupanga gawo logwira ntchito, loyesedwa lomwe limakhala ngati mtundu womaliza wopangira, pogwiritsa ntchito njira zomwezo. Cholinga sichimangokhala mawonekedwe - ndi mawonekedwe oyimira, ma angles, mapeto a pamwamba, ndi zovuta zonse zomwe zimachokera kutsanulira zitsulo mu nkhungu yamchenga. Nthawi zambiri ndimawona mapulojekiti akuyimitsidwa chifukwa chofananiracho chinapangidwa kuchokera kunjira ina, ndipo zomwe zayesedwa sizinamasuliridwe. Ndilo kusiyana kwachitsanzo kuponya mchenga kumafuna kutsekereza.
Lingaliro Lachikulu: Kukhulupirika Kuposa Chipolishi
Phindu lalikulu logwiritsa ntchito mchenga pochita chitsanzo ndi kukhulupirika. Mukudzipereka ku zenizeni za ndondomekoyi mofulumira. Ngati gawo lanu lomaliza likhala kuponya mchenga, ndiye kuti prototype yanu iyeneranso kukhala. Izi zimakakamiza kuti zokambirana za manufacturability (DFM) zizichitika koyambirira, osati ngati zongoganizira. Mudzawona komwe mukufunikira kukonzekera, mudzamva kulemera kwachitsulo, mudzamvetsetsa nokha zovuta zomwe zikukuvutitsani. Ndi mphunzitsi wankhanza koma woona mtima. Chojambula chopangidwa bwino cha billet chikhoza kuwoneka bwino pa desiki, koma sichikuwuzani kalikonse za momwe chitsulocho chidzayendera mu nkhungu, kumene shrinkage porosity ingachitike, kapena ngati kusintha kwa khoma lanu kuli koopsa kwambiri pa ntchito yoyambira.
Ndikukumbukira ntchito yomanga bulaketi yachida cha mafakitale. Chitsanzo choyamba cha kasitomala chinali CNC chopangidwa kuchokera ku mbale yolimba ya aluminiyamu. Zinakwana, zinagwira ntchito. Iwo greenlit chida kwa mkulu-pressure kufa kuponyera. Kuwombera koyambirira kuchokera kukufa kwapangidwe kunali kodzaza ndi zotsekera zozizira komanso zodzaza zosakwanira. Chifukwa chiyani? Makina opangidwa ndi makinawo anali ndi ngodya zakuthwa zamkati zomwe zinali zosatheka kuti chitsulo chosungunula chidzaze mwachangu. Kuponya mchenga kosavuta, ngakhale kovutirapo, kukadawonetsa kuti geometry ndi vuto. Tikadawona kufunika kwa radii. Ndilo phunziro lomwe limawononga makumi masauzande mumafa okonzedwanso.
Apa ndipamene mnzako yemwe ali ndi chidziwitso chozama kwambiri sangakambirane. Mukufunikira wina yemwe angayang'ane chitsanzo cha CAD ndikuwona nthawi yomweyo nkhungu, mzere wolekanitsa, ma cores. Kampani ngati Malingaliro a kampani Qingdao Qiangsenyuan Technology Co., Ltd., ndi zaka zawo 30 akusewera, imagwira ntchito mumlengalenga mwachilengedwe. Sikuti amangopanga nkhungu; ndi za upangiri wa momwe mungasinthire kapangidwe ka nkhungu kuti chithunzicho chikhale chopambana-ndiponso, gawo lomaliza - lopambana. Ntchito yawo yonse chipolopolo nkhungu kuponyera, kupanga ndalama, ndi ma aloyi osiyanasiyana amatanthawuza kuti amamvetsetsa mawonekedwe, kotero amadziwa nthawi ndi chifukwa chake angapangire mchenga kuti ukhale wofanana.
Njira: Yachangu, Yakuda, ndi Yodziwitsa
Ndiye, zimagwira ntchito bwanji kwa nthawi imodzi kapena yochepa? Nthawi zambiri ndi njira yapamanja kapena ya theka lamanja. Simukupanga chokhazikika, chogwiritsidwanso ntchito pamakina omangira. Mwachidziwikire, mukupanga mawonekedwe abwino kuchokera ku sing'anga ngati bolodi la urethane kapena thovu lokwera kwambiri. Njirayi imagwiritsidwa ntchito popanga nkhungu yamchenga, nthawi zambiri pogwiritsa ntchito mchenga wosaphika mwachangu. Chikombolecho chikhoza kukhala chophweka cha magawo awiri ndi kukoka, kapena chingafune zidutswa zotayirira. Cholinga chake ndikujambula ma geometry, osati kukwaniritsa gawo lapamwamba la kupanga.
Kusankha kwachitsulo ndikofunikira. Mukufuna kufananiza, momwe mungathere, aloyi yomwe imapangidwira kupanga. Ngati gawo lomaliza liyenera kukhala chitsulo cha ductile, chitsanzo chanu chiyenera kutsanuliridwa muzitsulo zachitsulo. Izi zimayesa madzi a aloyi enieniwo, kuchepa kwake, zofunikira zake zodyetsa. Kutsanulira prototype mu aluminiyamu pamene kupanga adzakhala chitsulo pafupifupi opanda ntchito pa zinthu khalidwe mbali. Ili ndi gawo lina lomwe ukatswiri wazinthu zoyambira ndizofunikira. Zochitika za QSY ndi chitsulo chachitsulo, chitsulo, chitsulo chosapanga dzimbiri, ndipo ngakhale apadera zitsulo zopangidwa ndi nickel zikutanthauza kuti akhoza kukutsogolerani kuzinthu zoyimira, ngakhale zachiwonetsero. Kutentha kwamphamvu kothira chitsulo chapamwamba ndi dziko losiyana ndi chitsulo chotuwa.
Zotsatira zake ndizofunikanso ngati kuthira. Inu mumagwedeza kuponyedwa, kudula zipata ndi zokwera, ndiyeno inu mumawona kwenikweni zomwe inu muli nazo. Kuwoneka koyamba kumanena nthawi zonse. Mutha kuwona kabowo kakang'ono kowoneka bwino mugawo lokhuthala, kutsimikizira kuti mukufuna chokwera chokulirapo. Mutha kuona mchenga ukuyaka pagawo lopyapyala, kusonyeza kuti chitsulocho chinali chotentha kwambiri kapena gawolo ndi lopyapyala kwambiri kuti lingadzaze bwino. Izi ndi zosasinthika, ndemanga zaposachedwa. Kenako mumayeretsa pang'ono-mwinamwake kuphulika mwachangu ndikudutsa mzere wotsatsira ndi chopukusira - zokwanira kuti zitheke kuyesa. Cholinga ndikuchiyika muzitsulo kapena pamakina kuti muwone ngati ikugwira ntchito, ndipo koposa zonse, momwe imalephera ngati itero.
Pamene Ndi Chida Choyenera (Ndipo Pamene Sichiri)
Kuponyera mchenga kwa prototype kumawala pazinthu zina. Zigawo zazikulu, kwa imodzi. Nthawi zambiri ndiyo njira yokhayo yotsika mtengo yowonetsera chinthu chomwe chimakhala ndi mita kapena kupitilira apo. Zigawo zolemera ndi zina zabwino, monga njira zina zowonetsera mofulumira zimalimbana ndi zitsulo zolimba. Ndiwoyeneranso magawo omwe ali ndi zibowo zamkati zomwe zimafuna ma cores a mchenga. Mutha kufanizira njira yodzipangira yokha. Ndipo, ndithudi, ndizofunikira pamene zinthu zakuthupi za alloy yoponyera ndizofunika kwambiri pa mayesero, monga kukana kutentha kwa alloy. cobalt-based alloy kapena kukana dzimbiri kwa giredi inayake yosapanga dzimbiri.
Koma si panacea. Pazigawo zing'onozing'ono, zatsatanetsatane komanso zololera zolimba, kuyika ndalama kungakhale njira yabwinoko, ngakhale gawo lopangira mchenga, kungoyang'ana zoyenera komanso mawonekedwe. Ngati mukufuna ma prototypes khumi ndi awiri ofanana a batch yoyeserera, zachuma zitha kukufikitsani ku nkhungu yanthawi yayitali kapena kupanga makina. Ndipo ngati kutsirizitsa kwapamwamba kapena kulondola kwapang'onopang'ono ndizomwe zimakhudzidwa kwambiri ndi mayeso, ndiye kuti ndibwino kuti muyambe kupanga makina. Kulimba kwa pulojekiti yamchenga ndikuyesa kupangidwa ndi ntchito zambiri zamapangidwe opangira mchenga.
Chitsanzo chothandiza: tidagwirapo kale fanizo la mapangidwe osiyanasiyana. Geometry inali yovuta, yokhala ndi ndime zodutsana. Njira yopangira inali yopangira zipolopolo. Tidagwiritsa ntchito kuponya mchenga (moyenera njira ya mchenga wobiriwira) kuyesa kapangidwe kake. Chitsanzocho chinavumbula vuto lalikulu la chipwirikiti m'ndime imodzi yomwe ikanapangitsa kupanga zinyalala. Tinapanganso makina othamanga kutengera mtundu umodzi womwewo. Pamene tinasamukira ku chenicheni chipolopolo nkhungu kuponyera njira yopangira chisanadze, vutolo linali litathetsedwa kale. Chitsanzocho sichinkawoneka chokongola, koma chinapulumutsa polojekitiyo.
Zopinga Zowoneka ndi Zosankha Zenizeni
Si zonse zowongoka. Chimodzi mwazinthu zowawa kwambiri pamutu ndi kupanga mapangidwe. Kwa chowonadi chimodzi, kuwononga makina opangidwa mu nkhungu ndikovomerezeka. Koma ngati mukuganiza kuti mungafunike kutsanulira awiri kapena atatu kuti mubwereze, mukufunikira chitsanzo chokhazikika. Izi zimakweza mtengo woyamba ndi nthawi. Pali kusinthanitsa kosalekeza: kodi timayika ndalama zingati pazida zofananira (patani) motsutsana ndi kungotenga zitsulo m'manja?
Mfundo ina yosaoneka bwino ndi mchenga weniweniwo. Zopangira zopangira zimagwiritsa ntchito mchenga woyendetsedwa mwamphamvu, wobwezerezedwanso ndi zowonjezera zina. Ogulitsa zofananira atha kugwiritsa ntchito mchenga wosiyanasiyana. The matenthedwe katundu amasiyana. Izi nthawi zina zimatha kuyambitsa kusiyanasiyana pang'ono kwa kuziziritsa komanso mawonekedwe apamwamba poyerekeza ndi kupanga komaliza. Muyenera kudziwa izi osati kutanthauzira mopitilira muyeso kusagwirizana kwapang'ono. Zomwe zimapangidwira pamakina, komabe, ziyenera kuyendetsedwa ndi chitsulo, osati mchenga.
Nthawi yotsogolera ndi chinthu china. Ndiwofulumira kuposa zida zopangira zopangira, koma sizimangokhala usiku umodzi. Muli ndi kupanga mapangidwe, kusonkhanitsa nkhungu, kutsanulira, kuziziritsa, ndi kugwedeza. Nthawi yeniyeni ya gawo lazovuta zapakati ndi masabata awiri kapena anayi. Apa ndi pamene kukonzekera kuli kofunika. Ndi gawo lomwe liyenera kulemekezedwa mu dongosolo lachitukuko chazinthu, osati mphindi yomaliza, timafunikira chipwirikiti chachitsulo.
Kuphatikiza ndi Masitepe Otsatira: CNC ndi Beyond
Kawirikawiri kuponya mchenga kwachiwonetsero kumangoyesedwa popanda makina. Ndilo ulalo wachilengedwe ku unyolo wathunthu wautumiki. Nthawi zonse mumayenera kumangirira nkhope zowoneka bwino, mabowo a bawuti, kapena malo osindikizira kuti mupeze mayeso olondola. Ichi ndichifukwa chake chitsanzo cha kampani yomwe imapereka zonse zoponya ndi CNC makina ndi wamphamvu kwambiri. Amatha kuthana ndi kuzungulira konse: kuwunikiranso kamangidwe, kupanga mapangidwe, kutsanulira, kugwedeza, kutentha ngati kuli kofunikira, ndiyeno kukonza bwino zinthu zofunika kwambiri pakuponya koyipa komweko.
Njira yophatikizikayi imathetsa mikangano yambiri yazinthu komanso kusalumikizana bwino. Katswiri wamakina sakungoganizira kumene pamwamba pake pamakhala chipwirikiti; iwo ali gawo la gulu lomwelo lomwe linapanga izo. Pamalo ngati QSY (https://www.tsingtaocnc.com), iyi ndiye njira yoyendetsera ntchito. Chitsanzocho chimachokera ku maziko, amawomberedwa, ndikusunthira kumalo ogulitsa makina. Ali ndi mtundu woyambirira wa CAD, ndipo amadziwa zomwe zili ngati zoponyedwa komanso zomwe ziyenera kusinthidwa kuti zifotokozedwe. Kupitilira uku ndikofunikira kwambiri pakusunga kukhulupirika kwachiwonetsero ndikuwonetsetsa kuti zotsatira za mayeso ndi zatanthauzo.
Pamapeto pake, prototype imakhala maziko akupanga. Dongosolo la mageti omwe mudatsimikizira, malo okwera omwe mudatsimikizira, kapangidwe kake komwe mudayesa - chidziwitso chonsechi chimatengera kapangidwe kake kapangidwe ndi nkhungu. Gawo lopangidwa bwino la mchenga silimangopereka gawo loyesa; zimabweretsa ndondomeko ya njira. Imachotsa pachiwopsezo cha ndalama zotsika mtengo zomwe zimabwera pambuyo pake. Imasandutsa zosadziwika za kapangidwe katsopano kukhala kuchuluka kodziwika, kapena, kukhala zongopeka zophunzitsidwa bwino. Ndipo mu bizinesi iyi, kulingalira kophunzitsidwa nthawi zambiri kumakhala kusiyana pakati pa kuyambika bwino ndi kulephera kokwera mtengo.
