Kuponyedwa kwa mchenga wa mphamvu yokoka kumakhalabe njira yopititsira patsogolo magawo a mafakitale omwe amafunikira kukhulupirika kwadongosolo, kukhazikika kwamafuta, komanso kutsika kotsika mtengo - makamaka pamene ma geometri ovuta akumana ndi zovuta zantchito. Koma si onse mphamvu yokoka mchenga kuponyera fakitale imapereka kulondola kosasinthasintha, zitsulo zobwerezabwereza, kapena kutsirizitsa kwapamwamba kwa zigawo zofunika kwambiri. Tawonapo ma valve ambiri a hydraulic valve akukanidwa pambuyo pa chithandizo cha kutentha chifukwa cha porosity yosazindikirika. Tasintha maziko a pampu adasokonekera panthawi yokonza chifukwa kulimba kwa nkhungu sikunatsimikizidwe kusanathire. Ndipo tatsatiranso kuvala msanga kwa ma winch center shaft rollers kubwereranso ku magawo osagwirizana ndi ma graphite nodule - osati cholakwika cha opareshoni, koma mipata yowonera zinthu.
Chifukwa Chake Gravity Sand Casting Imapambanabe Magawo Amafakitale Ochita Bwino Kwambiri
Kupanga ndalama kumapambana pazigawo zowonda zokhala ndi mipanda yamlengalenga. Die casting imayang'anira nyumba za aluminiyamu zapamwamba kwambiri. Koma kuponyedwa kwa mchenga wa mphamvu yokoka kumakhala ndi malo apadera pomwe kulemera kwake kumaposa 50 kg, makulidwe a khoma amasiyana kupitirira 25 mm, ndipo kusankha kwa aloyi kumaphatikizapo magiredi a faifi abrasive-resistant cobalt-nickel monga AMS 5387 kapena T800. Izi sizinthu zongoyerekeza. Pakutumizidwa kwapadziko lonse lapansi, nyumba ya silinda ya pampu ya piston yopangidwa ndi mchenga wokoka imakwanitsa 32% kukana kutopa kwamafuta kwambiri kuposa mnzake wochita nawo ndalama - chifukwa kulimba pang'onopang'ono kumalimbikitsa kutalikirana kwa mikono ya dendritic ndikuchepetsa kugawanika mu Co-based superalloys. Ndizo zoyezeka. Ndizobwerezabwereza. Ichi ndichifukwa chake ma OEM agalimoto zamainjiniya amafotokozera zoponyera mchenga m'malo ena opangira ma winch system shafts omwe amagwira ntchito mosalekeza 120 ° C.
Zomwe Zimalekanitsa Factory Yodalirika Yokokera Mchenga Ndi Ena Onse
Malo ambiri opangira mchenga amawongolera kapangidwe ka mchenga ndi chinyezi. Ochepa amawongolera unyolo wathunthu: zopangira zopangira zovomerezeka, mapu ophatikizika a nkhungu, kuyang'anira zenizeni zenizeni za metallostatic panthawi yothira, ndi kutsimikizira kwapang'onopang'ono kwa microstructure kudzera pa ASTM E112 kusanthula kukula kwambewu. Pamalo athu ogwirizana ndi ISO ku Qingdao, gulu lililonse la mphuno za cobalt alloy limayamba ndi ingot yotsimikizika yapawiri ya T800-yotsimikizika pa C, Cr, Ni, ndi Si zomwe zili motsutsana ndi malipoti oyesa mphero * asanasungunuke. Timajambula kuuma kwa nkhungu kudutsa mfundo 36 popirira ndikukoka pogwiritsa ntchito zoyesa zoyeserera - osati pakatikati pokha, koma m'makona omwe ma gradient amawotcha amayambitsa kukula kosagwirizana. Pakutsanulira, timayika kutentha kwa ladle masekondi 15 aliwonse ndikugwirizanitsa ndi deta ya thermocouple yomwe ili mu nkhungu. Palibe zongoyerekeza. Palibe zongoganizira za "standard practice".
Chilango ichi chimalipira pazokolola - ndi magwiridwe antchito. Pazigawo zapampu za AMS 5387, chiwongola dzanja chathu chapakati pa gawo loyamba ndi 94.7%, choyezedwa ndi GD&T callouts pazithunzi za ASME Y14.5–2018. Umenewo si mwayi. Ndi zotsatira za kuphatikiza kayeseleledwe (pogwiritsa ntchito MAGMAsoft) ndi CNC fixture design-kotero machining allowances amagwirizana ndendende ndi zonenedweratu zolimbitsa thupi ma vectors. Makasitomala samapeza "zamwano". Amapanga makina opangidwa mkati mwa ± 0.05 mm pamalo osindikizira ovuta-popanda kukonzanso.
Kumene Kupanga Zophatikiza Kumathetsa Mavuto Enieni
Ena amati kuponya mchenga kwachikale. Koma zenizeni zimafotokoza nkhani yosiyana: ma valve odalirika kwambiri masiku ano amaphatikiza matupi oponyedwa mchenga ndi ma CNC opangidwa ndi makina oyenda mkati ndi malo okhala ndi laser. Ndiko kupanga kosakanizidwa - osati ngati buzzword, koma ngati chofunikira. Gulu la vavu loponyera ndalama la monolithic limatha kupirira zolimba, koma limalephera pansi pa ma cyclic pressure spikes chifukwa kapangidwe kake kabwino kamasokonekera kopanda kulimba kwa mchenga wowongolera-kuzizira. Pakadali pano, zofananira ndi makina a CNC kwathunthu kuchokera ku zinyalala za 68% yazinthu ndipo zimatenga 3.2 × kutalika kuti apange.
Timatseka kusiyana kumeneko. Kuphatikizika kwathu koyima kumatanthauza gulu lomwelo lomwe limatsimikizira zojambula zanu kuti zisasunthike komanso pulogalamu ya 5-axis milling Center yomwe imamaliza chibowo chamkati cha maziko anu apompo. Palibe ma handoffs. Palibe kutayika komasulira. Wogula atapempha pulagi ya cobalt alloy yosakhazikika yokhala ndi kulolerana kwa 0.02 mm pa nkhope ya 120 mm OD, sitinanene kuti "sizingatheke." Tinasintha ma core print geometry, kuwonjezera kayeseleledwe ka malo oziziritsa, ndikuyesa kuyesa kocheperako komwe kumayesedwa ndi akupanga. Zotsatira zake? Zero amakana mayunitsi 240. Imaperekedwa m'masiku 18 - osati masabata 12.
Kusankha Fakitale Yanu Yopangira Mchenga Wokokera: Macheke Atatu Osakambirana
Musanasaine NDA kapena kutulutsa PO, funsani mafunso awa-ndipo funsani umboni:
- Kodi mungandiwonetse zipika zoyendera zamtundu wapita wapita wamagulu a AMS 5387-kuphatikiza kutsimikizira kwazithunzi ndi malipoti oyeserera? Ngati akayikira, chokanipo. Kutsatizana sikuli kofunikira pakupanga kwapamwamba kwambiri.
- Kodi mumayang'ana mumchenga wobiriwira musanathire - kapena pongomaliza? Kutsimikiza kwa nkhungu kumagwira molakwika msanga. Kudalira kokha pakuwunika komaliza kumatanthauza kutaya, osati kuwongolera.
- Kodi ndondomeko yanu yolembedwa yotsimikizira kuti microstructure homogeneity ndi yotani pa gawo la 400 mm? Muyezo wa ASTM E3 umafunika magawo atatu osachepera pa chitsanzo. Chilichonse chocheperako chimaphonya banding kapena tsankho la carbide.
QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD. amamanga mbali zachitsulo mwatsatanetsatane-osati kungojambula. Valavu iliyonse yokakamiza, nyumba ya silinda iliyonse, nozzle iliyonse ya cobalt imayamba ndi cholinga chachitsulo ndipo imatha ndi kutsimikizika kogwira ntchito. Sitimapereka khalidwe lakunja. Timazipanga kuti izi zitheke kuyambira pakusankha mchenga mpaka lipoti lomaliza la CMM. Pomwe kufunikira kwapadziko lonse kukukulirakulira kwa zida zolimba, zokhala ndi aloyi wapamwamba kwambiri, kumanja mphamvu yokoka mchenga kuponyera fakitale sichidzangokwaniritsa zofunikira. Imayembekezera njira zolephereka, kufewetsa njira yanu yoperekera zinthu, ndikupereka magawo omwe amachita-kuzungulira mozungulira, chaka ndi chaka.
