Mainjiniya akamatchula zida zolondola zama hydraulic system, mapampu akumunda wamafuta, kapena mawilo olemetsa, samangofunika magawo - amafunikira kutsimikizika kwa dimensional pansi papsinjika. Ichi ndichifukwa chake kufufuza kuchokera ku zenizeni fakitale yopanga zinthu zopangira ndalama nkhani-osati monga wogulitsa, koma monga luso lowonjezera la gulu lojambula. Ku QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD., Tawonapo ntchito zambiri zikuyimitsidwa chifukwa ma projekiti adafika ndi kuchepa kwapang'onopang'ono m'malo ovuta kusindikiza, kapena chifukwa mabotolo opangidwa ndi makina adasokonekera 0.015 mm kunja kwa GD&T callouts-zolakwa zosawoneka ndi maso koma ntchito yowopsa. Timakonza mipata imeneyo pagwero.
Chifukwa chiyani "Investing Casting Supplies Factory" Sichilemba Chabe - Ndi Kudzipereka Kwa Njira
An fakitale yopanga zinthu zopangira ndalama ayenera kuchita zambiri kuposa kutsanulira zitsulo mu zipolopolo za ceramic. Iyenera kuwongolera kusasinthika kwazitsulo pa kutentha, kusunga kapangidwe ka tirigu kudzera mu chithandizo cha kutentha, ndikugwira ± 0.02 mamilimita kulolerana pazinthu monga ngodya zapampando wa valavu kapena pisitoni yotulutsa pistoni - osadalira kukonzanso pambuyo poponyedwa. Pamalo athu a Qingdao, nozzle iliyonse ya AMS 5387 cobalt alloy imayamba ndi zida zotsimikizika za T800-grade, zotsimikiziridwa ndi kusanthula kwazithunzi zisanasungunuke. Palibe gulu lomwe limalowa m'ng'anjo popanda zipika zama chemistry. Sitipanga zida zapakatikati kapena zomanga zipolopolo-timayang'anira zonse m'nyumba, chifukwa kusiyanasiyana kwa zipolopolo kumakhudzanso kutha kwa pamwamba ndi kugwedezeka kwapampu m'mapampu okhala ndi mipanda yopyapyala.
Taziyeza: kupatuka kwa 5% mu nthawi yowumitsa zipolopolo kumawonjezera porosity mu cobalt-nickel castings ndi 22% - zokwanira kuchititsa kutopa msanga pakugwiritsa ntchito mozungulira kwambiri. Ntchito zathu mazenera ndi opapatiza, zolembedwa, ndi kutsatiridwa. Izo sizowonjezera-injiniya. Ndimomwe mumapewa kulephera kwamunda pamene pulagi ikulephera pa 4,000 psi mu mpope wa jakisoni wakunyanja.
Maluso Anayi Omwe Amathetsa Zowonongeka-ndi Zowopsa Zobisika
Otsatsa ambiri amalekanitsa kuponya, kukonza, ndi kumaliza. Izi zimapanga magawo atatu pomwe kulolerana kumachulukirachulukira, kukhulupirika kwapamtunda kumasokonekera, ndikusokonekera kwa kuyankha. Timagwirizanitsa zonse zinayi:
- Kuponya: Mizere yopangira ndalama ndi mchenga yolinganizidwa kuti ikhale yazitsulo kuyambira pa ductile iron (ASTM A536) mpaka AMS 5387 cobalt superalloys—palibe zoikamo “zapamwamba” zamtundu uliwonse, mbiri yazambiri yotentha yokha.
- Machining: Malo a 5-axis CNC okhala ndi zozungulira zowunikira zomwe zimatsimikizira kuti ndizovuta kwambiri * asanadutse * komaliza - makamaka m'nyumba za asymmetric cylinder komwe kusalinganika bwino kumawononga mphamvu zama hydraulic.
- Kutentha Chithandizo: Zing'aniro zovundikira pamzere zowunikira nthawi yeniyeni, osati mavuni amagulu. Timatsimikizira kulimba kwa ma gradients pamagawo osiyanasiyana a ma winch center shaft roller-osati kungowerenga pamwamba.
- Kumaliza: Electropolishing kwa maziko zosapanga dzimbiri mpope zitsulo; Kupaka kwa HVOF kwa ma nozzles a aloyi a cobalt owululidwa ndi slurry ya abrasive. Kuuma kwapamtunda kumayesedwa-osaganiziridwa.
Kuphatikizika koyima uku sikungokhudza kupulumutsa mtengo kokha. Ndizokhudza kuchotsa "bokosi lakuda" pakati pa kuponyera shrinkage ndi geometry yomaliza. Makasitomala akatumiza chojambula cha ma valve opanikizika, mainjiniya athu amawunika ngati kusintha kwa khoma loponyera kungayambitse kupsinjika kotsalira-ndikusintha mayendedwe kapena kusintha makinawo moyenerera. Kuzindikira kumeneko kumangobwera chifukwa chogwira ntchito zonse ziwiri mu shopu imodzi.
Zomwe Amisiri Amafunsa-Ndipo Zomwe Sanena Mokweza
"Kodi mutha kugwira 0.01 mm pachibowo ichi?" ndi funso. Chosaneneka ndi chakuti: "Kodi gawoli lidzapulumuka maulendo 10,000 pa 150 ° C popanda micro-cracking?" Timayankha zonse ziwiri-poyesa, osati kulonjeza. Chigawo chilichonse cha mpope cha AMS 5387 chimayang'aniridwa ndi akupanga * ndi * magawo a zitsanzo kuchokera kutentha kulikonse. Timapanga mapu a dendrite pamtaliano. Timagwirizanitsa ma profiles olimba ndi zotsatira zoyeserera. Ngati kasitomala akufuna zolembedwa kuti ASME BPVC Gawo VIII zitsatire, timapereka malipoti a kutentha kwathunthu, osati chidule.
Timalengezanso zomwe * sizingagwire * ntchito. Mwachitsanzo: T800 alloy amakana kuvala-koma makina ake amatsika kwambiri kuposa 35 HRC. Chifukwa chake ngati chojambula chimafuna malo olimba * ndi * ulusi wothina wamkati, tikupangira ulusi wa EDM pambuyo pa kutentha kwa kutentha m'malo moyika pachiwopsezo kusweka kwa zida ndi kupotoza kwa ulusi. Zowona zamtundu wotere zimapulumutsa masabata - osati pamalo ogulitsira, koma pakuyesa kutsimikizira.
Kudalirika Kumayamba Kalekale Asanayambe Kuthira Koyamba
A odalirika fakitale yopanga zinthu zopangira ndalama sichikuyambira pa chitseko cha maziko. Zimayamba ndi kutsatiridwa kwa zinthu mpaka pa nambala yosungunula, kumapitilira kutsimikizira kwa CMM kwa zitsanzo zoyambirira pogwiritsa ntchito makina odziwika ndi kasitomala, ndikumaliza ndi kutsata komwe kumaphatikizapo malipoti am'mbali - osati mindandanda yonyamula. Timatumikira ma OEM aku North America omwe amafunikira kutumizidwa kwa PPAP Level 3, ogawa aku Europe omwe amawunika njira zathu za ISO 9001:2015 pachaka, komanso omanga mapampu aku Southeast Asia omwe amafunikira nthawi zotsogola zokhazikika ngakhale mitengo ya cobalt ikusinthasintha.
Cholinga chathu chotsatira? Njira zophatikizira-monga kuyika ndalama kwapafupifupi komwe kumangokhala ndi 0.3 mm yokhayo kuti amalize CNC yomaliza. Kuwononga zinthu zochepa. Kuwongolera kwa microstructure. Kupititsa patsogolo mwachangu. Osati chifukwa ndi buku - koma chifukwa limathetsa vuto lenileni: kupeza zofunikira za mishoni moyenera, panthawi yake, popanda kunyengerera.
