Akatswiri akamanena za kuponyedwa kwa zitsulo zolimba kwambiri, makamaka m'makina a hydraulic, mavavu amafuta & gasi, kapena nyumba zapampu zolemetsa - samangosankha njira. Akusankha mnzawo yemwe amawongolera kusasinthika kwazitsulo, kubwerezabwereza, komanso kudalirika kwa magwiridwe antchito kuchokera ku aloyi yaiwisi kupita ku gawo lomaliza. Ichi ndichifukwa chake magulu ogula zinthu padziko lonse lapansi akutembenukira ku apadera fakitale yokoka mphamvu yokoka ntchito - osati zoyambira wamba - zokhala ndi kuthekera kophatikizika, kutsata zolembedwa, komanso chidziwitso chotsimikizika mu ma superalloys monga AMS 5387 ndi T800.
Chifukwa Chake Gravity Casting Imapambanabe Pazigawo Zofunika Kwambiri Pamafakitale
Kutulutsa kwamphamvu yokoka sikutha. Zimasankhidwa mwadala mukafuna zowuma zowuma, zocheperako zokhala ndi zowongolera zolimba zamakina-makamaka pazigawo zomwe zimakumana ndi zovuta za cyclic kapena kuvala kwa abrasive. Mosiyana ndi kuponyera kwamphamvu kwambiri, chitsulo chosungunuka chopangidwa ndi mphamvu yokoka chimalowa mu nkhungu pang'onopang'ono, kuchepetsa chipwirikiti ndi kutsekeka kwa mpweya. Chotsatira? Kulimba kwamphamvu kwambiri, kukana kutopa kwabwinoko, komanso kuchita bwino kwambiri pambuyo poponyedwa-zofunika kwambiri pazinthu monga pisitoni ya silinda yapampu kapena matupi okakamiza a valve komwe kuchepa kwapang'onopang'ono kapena voids mkati kungayambitse kulephera kwamunda.
Tawona makasitomala akusintha kuchokera kuzinthu zina zopangira ndalama pambuyo pophwanya mobwerezabwereza ma nozzles a cobalt-nickel omwe amagwira ntchito pamwamba pa 450 ° C. Kuponyera kwa mphamvu yokoka kunapangitsa kuti mbewuyo ikhale yofanana - ndipo makamaka, inalola kuyika bwino kwa zokwera ndi zodyetsa kuti zitsimikizire kulimba kolowera. Mlingo wa kayendetsedwe kameneka suchitika mwangozi. Pamafunika kuzindikira kozama kwazitsulo, zaka makumi angapo zolumikizirana ndi magawo, komanso kuyang'anira kutentha kogwirizana ndi ISO pakuthira kulikonse.
Maluso Anayi Osakambirana mu Factory Gravity Casting Yapamwamba
A wokhoza fakitale yokoka mphamvu yokoka ayenera kupereka zambiri kuposa zitsulo zotsanuliridwa. Izi ndi zomwe zimalekanitsa abwenzi okonzekera kupanga ndi ogulitsa malonda:
- Kukhoza kwazinthu kupitirira magiredi wamba: Sikuti ma aloyi onse a cobalt amachita chimodzimodzi. AMS 5387 imayankha mosiyana ndi mitengo yozizira kuposa mitundu yochokera ku T800. Katswiri weniweni amasunga mgwirizano waukadaulo ndi ogulitsa zinthu zovomerezeka - ndikutsimikizira kutentha kulikonse motsutsana ndi ASTM E112 (kukula kwambewu), ASTM E353 (kuwunika kwamankhwala), ndi ma curve odziwika ndi kasitomala.
- Kukhazikika kwapang'onopang'ono panjira zosakanizidwa: Zambiri zopangira mphamvu yokoka zimafunikira makina a CNC pambuyo pake. Ngati nyumba yoponyerayo ilibe malo ake opangira makina - kapena ilibe ma CMM otha GD&T pamalopo - chiwopsezo chochulukirachulukira chikuchulukirachulukira. Tayezera mpaka ± 0.12 mamilimita kupatuka pamayendedwe ovuta kwambiri pamene kuponyera ndi makina zidagawika pakati pa ogulitsa.
- Kufufuza kwathunthu mpaka pa chipika chosungunuka: Pamafuta & gasi kapena ma hydraulic OEMs, "traceable" amatanthauza kudziwa kuti ndi ndalama yanji yomwe idapangidwa ndi ng'anjo yomwe idaponyedwa, kuzungulira kwa kutentha komwe idachitika, komanso ndi wogwiritsa ntchito yemwe adasaina pakuwunika komaliza. Palibe zipika zamapepala. Palibe kulosera kwa nambala ya batch.
- Kutsimikizira kogwira ntchito-osati kutsata kwapang'onopang'ono: Nyumba ya valve yokakamiza imatha kudutsa macheke a CMM koma ikutsika pansi pa bar 350. Mafakitole apamwamba amayesa kuyesa kwa hydrostatic, kuyang'ana kolowera utoto pa ASTM E165, komanso kutsimikizira kwamayendedwe amayendedwe asanatulutse zolemba zoyambirira.
Zomwe Ntchito Zowona Zapadziko Lonse Zimawulula Zokhudza Kukhwima kwa Njira
Ganizirani za kuyitanitsa kwaposachedwa kwa zodzigudubuza zamagalimoto okwera pa winch center shaft. Gawoli linkafunika kulimba kwa 42 HRC, kutha kwa pamwamba ≤Ra 0.8 µm pamabuku onyamula katundu, ndi zero porosity mkati mkati mwa 5 mm ya mpando wonyamula. Wopanga ma generic adalemba masabata 12 ndikukana udindo wosintha ma microstructure. Yankho lake linachokera kumalo omwe ankachitira mchenga * ndi * kutentha m'nyumba, kugwiritsa ntchito spectroscopy optical emission spectroscopy pa ladle iliyonse, ndikutsimikizira mbiri yolimba yokhala ndi mapu a Rockwell B/C. Chivomerezo cha nkhani yoyamba chinatenga masiku 8—osati miyezi.
Mlandu wina unakhudza mapulagi a cobalt alloy amisonkhano yapampu ya subsea. Ma geometry anali ndi zigawo zokhala ndi mipanda yopyapyala (2.3 mm mwadzina) ndi ma radiyo amkati ang'onoang'ono ngati R0.5 mm. Maonekedwe a mageti okhazikika adapangitsa kuzizira msanga komanso kutsekeka kozizira. Wothandizira wopambana adakonzanso makina othamanga pogwiritsa ntchito pulogalamu yoyeserera yolimba - ndikutsimikizira mtunduwo ndi ma gradients opangidwa ndi mapu a thermocouple panthawi yoyeserera. Kubwereza kotereku kumangogwira ntchito pomwe mainjiniya opangira zinthu amakhala pambali pa metallurgists ndi opanga mapulogalamu a CNC tsiku lililonse.
Kusankha Wokondedwa Wanu: Kupitirira Mabulosha ndi Zikalata
Zitsimikizo ndizofunikira-koma ndizinthu zaukhondo, osati zosiyanitsa. ISO 9001 ndi magawo a tebulo. Chomwe chimasuntha singanoyo ndi umboni wakuthana ndi vuto lapadera: Kodi amasindikiza maphunziro okhudzana ndi kusintha kwabwino kwa hydraulic valve casting? Kodi atha kugawana zambiri zoyerekeza zotentha kuchokera ku 10 AMS 5387 kuthira kwawo komaliza? Kodi malipoti awo a QC akuphatikizapo zithunzi za microstructure-osati manambala olimba okha?
Yang'aniraninso mbendera zofiira: Mapangidwe amtundu "okwanira-onse", kulephera kugwira ± 0.05 mm pazidziwitso za cast-in datum, kapena kudalira zotchinjiriza za gulu lachitatu popanda kutsimikizira njira yolumikizirana. Kuthekera kumeneku kumagawika—osati kusakanizidwa bwino.
Kwa mainjiniya omwe amapeza zida zoponya mphamvu yokoka lero, lingaliro silikhudza mtengo pa kilogalamu. Ndi za mtengo wonse wa umwini: kukonzanso pang'ono, kuzungulira kwa NPI mwachangu, ndi kulephera kwa zero pazigawo zomwe zimapangitsa kuti mapampu azithamanga, ma valve osindikiza, ndi magalimoto kugwira ntchito m'malo ovuta kwambiri. Kudalirika kumeneko kumayamba ndi a fakitale yokoka mphamvu yokoka zomwe zimagwira kutsanulira kulikonse ngati kuyesa koyendetsedwa-ndi kasitomala aliyense wojambula ngati mawonekedwe ogwirira ntchito.
