Anthu ambiri akamva 'zigawo zoponyera bwino', amajambula zinthu zopanda cholakwika, zooneka ngati ukonde, ngati zimatuluka mu nkhungu nthawi zonse. Ndiwo gloss yotsatsa. Chowonadi, kugaya tsiku ndi tsiku, ndikukambirana kosalekeza pakati pa lonjezo la ndondomekoyi ndi kuuma kwa physics. Sizongokhudza kupeza kulolerana kolimba; ndi kudziwa zomwe kulolerana ndi ofunika kumenyera pa gawo anapatsidwa, ndi kumene inu mukhoza kulola ndondomeko kupuma popanda kunyengerera ntchito. Zolemba zambiri zimaponyedwa mozungulira popanda kumvetsetsa kuchuluka kwa mtengo ndi phindu pashopu.
Masewera a Zipolopolo: Zoposa Mchenga Wokha
Tengani chipolopolo cha nkhungu. Dzinali limapangitsa kuti limveke molunjika-pangani chipolopolo, kutsanulira zitsulo. Koma kugwirizana kwa utomoni-mchenga kusakaniza? Ndipamene zaka zakumva zimadza. Gulu lomwe latsika pang'onopang'ono mu catalyst ratio sililephera nthawi yomweyo. Zimalephera masabata pambuyo pake, pamene kuponyedwa kumatuluka ndi pamwamba pakuwoneka ngati gritty, osati yosalala, chifukwa mphamvu ya chipolopolo sichinali yunifolomu. Tinaphunzira izi movutikira poyendetsa nyumba zopopera kasitomala. Ziwalozo zinadutsa macheke a dimensional, koma mapeto ake anali amalire. Wothandizirayo adawakana. Chifukwa chake? Kusinthasintha kwa kutentha m'chipinda chosanganikirana tsiku lomwelo komwe kunasintha mphamvu yakuchiritsa. Tsopano, kuwongolera chilengedwe m'dera lokonzekera sikungatheke kukambirana, ngakhale kumawoneka ngati tsatanetsatane waung'ono.
Ndicho chinthu chake mwatsatanetsatane kuponya mbali. Kulondola kumayamba kalekale chitsulo chosungunuka chisanawone nkhungu. Zimayamba ndi zopangira ndi nyengo zomwe zimagwiridwa. Kwa kampani ngati Qingdao Qiangsenyuan Technology Co., Ltd. (QSY), yomwe ili ndi zaka makumi atatu mu izi, kukumbukira kwa mabungwe ndiko chuma chenicheni. Simungagule nkhokwe yamtundu wotereyi. Kugwira ntchito kwawo kwanthawi yayitali kukuwonetsa kuti apanga laibulale yolimba yopangira magawo osiyanasiyana amitundu ndi zida, zomwe ndizofunika kwambiri kuposa chida chilichonse chatsopano.
Ndipo geometry ndi mfumu. Kuumba kwa zipolopolo ndikosangalatsa kwambiri pakuvuta kwapakatikati, koma mukalowa mumayendedwe amkati kapena njira zochepetsera zomwe zingafune ma cores ovuta komanso osalimba, malingaliro anu amayenera kulumphira kunjira ina. Mumayamba kuyeza mtengo wamagulu akuluakulu pakuumba zipolopolo motsutsana ndi pafupifupi ufulu wonse wa geometric woyika ndalama. Ndi mayendedwe okhazikika amalingaliro.
Investment Casting: Chinyengo cha Ufulu Wopanda Malire
Investment casting, kapena kutayika-sera, ndi chithunzi cha mwana mwatsatanetsatane kuponya mbali. The hype ndi za kujambula tsatanetsatane wodabwitsa, ndipo ndi zoona. Mutha kupanga zinthu zomwe zimawoneka ngati makina. Koma chinyengo ndi chakuti ndi njira imodzi yokha. Ndondomeko ya sera yokhayokha ndi yojambula. Kukanika kwa jekeseni, kutentha, ndi kuzizira kwa sera kumakhudzanso mbali yomaliza ya chitsulo. Kuzama pang'ono munjira ya sera kumatanthawuza kupatuka pakuponya.

Ndikukumbukira pulojekiti yopangira ma turbine blade prototype, pogwiritsa ntchito aloyi ya nickel. Zitsanzo za sera zinali zangwiro. Chigobacho chinkawoneka bwino. Koma titathira phula ndi kuwombera, tinali ndi zipolopolo zochepa zokhala ndi ming'alu ya tsitsi. Osati onse, owerengeka okha a gulu limodzi. Kulephera? Kutenthedwa kwa kutentha pa kutentha kwakukulu kwa autoclave dewaxing kunali koopsa kwambiri pa makulidwe a chipolopolocho m'madera ena a masamba. Tinasintha mlingo wokwera ndikuyambitsa siteji ya kutentha kwa magawo okhuthala. Vuto linathetsedwa, koma zidatiwonongera kuchedwa. Phunziro linali loti mayendedwe okhazikika siwofanana. Ndilo poyambira lomwe liyenera kukonzedwa kuti gawolo ligawike.
Apa ndipamene ukatswiri wazinthu, monga zomwe QSY imawunikira ndi ntchito yawo muzitsulo zapadera (zochokera ku cobalt, zotengera faifi tambala), zimakhala zovuta. Ma alloys awa sikuti amangolimbana ndi dzimbiri kapena kutentha kwambiri. Iwo amachita mosiyana pa kulimbitsa. Iwo ali osiyana shrinkage zinthu, osiyana kudya zofunika. Kutsanulira chitsulo chosapanga dzimbiri mu chipolopolo cha ndalama ndi chinthu chimodzi; kuthira aloyi ya nickel yochita bwino kwambiri ndi masewera ena a mpira kwathunthu. Dongosolo la mageti - ngalande zomwe zimadyetsa zitsulo mu gawoli - ziyenera kupangidwa mwapang'onopang'ono kuti zida izi zipewe kutsika kwa porosity m'malo ovuta. Simungangogwiritsanso ntchito kapangidwe kochokera kugawo lachitsulo cha kaboni.
Kugwirana Chanza Kwa Machining: Kumene Kuponya Kumakumana Ndi Zowona
Ayi mwatsatanetsatane kuponya gawo imatsirizikadi pa shakeout. Ndilo lingaliro lina lalikulu lolakwika. Lonjezo la 'near-net-shape' limatanthauza kuti mumachepetsa makina, koma simumachotsa. Mgwirizano pakati pa kuponyera ndi CNC Machining ndi wapamtima. Kuponyera kuyenera kupereka datum yodalirika - malo owonetsera - kuti wojambulayo agwedezeke ndikuyesapo. Ngati kuponyera kwasokonekera, kapena ngati mawonekedwe ofunikira sanapangidwe ndi zinthu zoyera zokwanira (zowonjezera) zopangira makina, chinthu chonsecho chikhoza kukhala chopanda pake pamakina.
Tidaphatikizira makina a CNC mnyumba pambuyo pamasewera amodzi odzudzula ambiri ndi malo ogulitsira akunja. Iwo anganene kuti zotulutsa zathu zatha, timati kukonza kwawo kunali kolakwika. Kuzibweretsa pansi pa denga limodzi, monga QSY yachitira ndi kuponyedwa kwawo kophatikizana ndi kukhazikitsidwa kwa makina a CNC, kumasintha zokambirana. Gulu lopanga makina limalankhula ndi gulu loyambitsa. Akhoza kunena, Hei, ngati mungatsimikizire nkhope ya flange iyi mkati mwa 0.5mm ya flatness, titha kuchepetsa nthawi yathu yopangira makina ndi 30%. Chigawo choyankhacho ndi golide. Imasintha njira zoyandikana kuchokera kwa adani kukhala othandizira.
Chitsanzo chothandiza: thupi la valve mu duplex zitsulo zosapanga dzimbiri. Maonekedwe opangidwa ndi ma bore amkati anali abwino, koma kuti asungidwe chisindikizo, amafunikira kumaliza bwino komanso kulolerana kolimba. Pokhala ndi gulu lopanga makina kuti liyenerere kusanja koyambirira kwa kuponya, chopangiracho chikhoza kusintha malo apakati mu nkhungu ya batch yotsatira kuti atsimikizire ngakhale kuchotsa katundu. Izi zidachepetsa nthawi yopangira makina komanso kuvala kwa zida kwambiri. Kugwirizana pa tsamba lawo la https://www.tsingtaocnc.com pakati pa kuponyera ndi makina si mndandanda wa ntchito; ndi filosofi yofunikira yopanga yomwe imayendetsa magwiridwe antchito ndi khalidwe.
Zosankha Zakuthupi: Maziko a Ntchito
Kusankha zinthu sikungokhudza katundu wa pepala. Ndi za castability. Chitsulo chachitsulo, mwachitsanzo, ndi kukhululukira. Imayenda bwino, imadyetsa bwino. Koma kusunthira kuzitsulo zamtundu wapamwamba kapena zosapanga dzimbiri, kusintha kwamadzimadzi kumasintha, mtundu wokhazikika umasintha. Mumapeza pasty, mushy solidification, yomwe imakonda kukhala ndi micro-porosity ngati siyikudyetsedwa bwino. QSY ikalemba ntchito zawo ndi chitsulo chosungunula, chitsulo, chosapanga dzimbiri, ndi ma aloyi apadera, ndiye luso lambiri. Banja lililonse limafunikira malingaliro osiyana.
Kwa chida chaulimi chovala kwambiri, chitsulo chowumitsa chikhoza kufotokozedwa. Koma kodi mungathe kuyiponya popanda ming'alu? Nthawi zina, yankho ndikupereka giredi yosiyana pang'ono yokhala ndi magwiridwe antchito ofanana koma mawonekedwe abwinoko. Ndiwo uinjiniya wowonjezera phindu. Sikungopanga zomwe zasindikizidwa; ikukambirana zomwe ziyenera kusindikizidwa kuti zikhale zodalirika komanso zotsika mtengo. Apa ndi pamene zaka 30 zogwira ntchito zikutanthawuza chidziwitso chakuya cha zipangizo.
Ma aloyi apadera ndi dziko losiyana. Iwo ndi okwera mtengo, kotero kuti ndalama zowonongeka ndi zoopsa. Njira iliyonse ndi yosamala. Chiŵerengero cha revert (recycled alloy) chimayendetsedwa mwamphamvu. Melt chemistry imawunikidwa ndikuwunikidwanso. Kutentha kothira ndikofunika kwambiri - kumatentha kwambiri, mumakhudzidwa kwambiri ndi chipolopolo cha ceramic; kwambiri, inu pachiswe mistuns. Kugwira ntchito ndi izi sikungoyambira nthawi zina. Zimafuna njira zodzipatulira komanso, zowonadi, mulingo wosiyana wa sitolo.
Muyeso Weniweni Wakulondola: Kusasinthika Kwa Nthawi
Choncho, chimene chimatanthawuza chabwino mwatsatanetsatane kuponya mbali wogulitsa? Sichitsanzo chimodzi chokha chomwe chimawoneka bwino. Ndichidutswa cha 10,000 pakupanga kofanana ndi 1st ndi 5,000th. Ndiwo mayeso ankhanza. Zimakhudza kuwongolera kwazinthu zomwe zimapulumuka kusintha kwa masinthidwe, kusiyanasiyana kwazinthu zakuthupi, komanso kuwongolera kwa zida.
Kusasinthasintha uku kumamangidwa pazolemba ndi chikhalidwe. Ndi zipika za ng'anjo, zolemba za jekeseni wa sera, kufufuza kwa tsiku ndi tsiku pa kagawidwe ka mchenga. Ndiko kufunitsitsa kuchedwetsa ndikufufuza ngati tchati chowongolera ziwerengero chikuwonetsa zomwe zikuchitika, ngakhale magawo ake akadali mwaukadaulo. Kampani yomwe yakhalapo kwa nthawi yayitali QSY idadziwa izi kapena sakadapulumuka. Makampani akulanga kwambiri.
Pamapeto pake, kuponya mwatsatanetsatane ndi luso lodzichepetsa lovala mawu apamwamba kwambiri. Ziwalozo zimatha kukhala zakuthambo kapena zida zamankhwala, koma zimayamba ndi anthu kuwonera kutentha, kuyeza ma viscosity, ndikuyang'ana malo ndi maso. Kulondola kwenikweni sikuli mu ma microns pajambula; ndi kubwerezabwereza kwa zisankho zazing'ono zosawerengeka zopangidwa molondola, tsiku ndi tsiku. Ndizo zomwe mukuguladi.
