Pamene mainjiniya amatchula a leveler gawo fakitale, sikuti amangoyitanitsa zitsulo-akutchova njuga nthawi yowonjezereka, kukhulupirika kwapamtima, ndi moyo wautumiki pa kukhazikika kwa dimensional pansi pa njinga yamoto ndi katundu wa abrasive. Tawona mapulojekiti ambiri akuyimitsidwa chifukwa gawo "lokhazikika" lokhazikika lidasokonekera pambuyo pa maola 200 a ntchito yamagetsi - kapena kulephera kuyesa kutayikira chifukwa cha micro-porosity m'malo oponya. Ichi ndichifukwa chake kulondola sikuli nthawi yotsatsa pano. Ndiko kusiyana pakati pa nyumba yapampu yokhala ndi 4,500 psi pa 120 ° C kapena kusweka panthawi yotumiza.
Chifukwa Chake Kusankha Zinthu Zakuthupi Kumakakamiza Kuchita Zosachepera—Osati Kungosintha
Zigawo zambiri zowongolera zimakhala ngati anangula amisonkhano yozungulira: ma roller a winch center shaft, nyumba za silinda, maziko a pampu. Ntchito yawo ndikusunga kuyanjanitsa pomwe imatenga kugwedezeka, kugwedezeka, ndi kupsinjika kwa cyclic. Koma ngati zoyambira zilibe kukhazikika kwamafuta kapena kufanana kwambewu, ngakhale kutsata kwangwiro kwa GD&T sikungalepheretse kugwedezeka. Ndipamene ma aloyi a cobalt-nickel monga AMS 5387 ndi T800 amasintha masewerawo.
Tayesa mitundu 12 ya alloy kudutsa 37 zenizeni zenizeni padziko lapansi. AMS 5387 imapereka kuuma kosasintha (38-42 HRC) pambuyo pochotsa yankho-ndipo movutikira, imasunga> 92% ya kuuma kumeneku pambuyo pa maola 1,000 pa 650 ° C. T800 imawonjezera kubalalitsidwa kwa chromium carbide pakukana kuvala mumafuta odzaza mchenga ndi gasi. Mu projekiti ina ya North Sea, ma nozzles a T800 adapitilira ma Inconel 718 ndi 3.2 × pakuyesa kukokoloka kwa slurry. Nsomba? Ma alloy awa amafunikira zida zapadera, kuwongolera kutentha, komanso kuwongolera kupsinjika pambuyo popanga makina. Sikuti sitolo iliyonse imatha kugwira ± 0.015 mm pa pulagi ya cobalt ya 320-mm popanda kupotoza. Ochepa amatsimikiziranso microstructure kudzera mu ASTM E112 kusanthula kukula kwambewu pa batch.
Kuphatikiza Kwa Vertical Kumathetsa Vuto la "Black Box" pakupanga kwa Leveler
Ogula ena amachokera ku Foundry A, amawapanga pa Shopu B, ndi kumaliza pa Coating C. Chiwombankhanga chilichonse chimakhala ndi chiopsezo cholakwika, kutentha kosavomerezeka, kapena kusagwirizana kwapamwamba. Timayendetsa casting, CNC, ndikumaliza pansi pa denga limodzi logwirizana ndi ISO-chifukwa magawo otsetsereka amalephera nthawi zambiri panjira, osati m'malo.
Njira yathu imayamba ndi kutsata kotsimikizika: ingot iliyonse ya cobalt imanyamula malipoti oyesa mphero ofananiza nambala ya kutentha ku ID yomaliza. Kuponyera ndalama kumagwirira ntchito zovuta zamkati; kuponyera mchenga kumapangitsa kulimba kukhala maziko akulu a pampu. Kenako makina opangira ma axis angapo amadula mawonekedwe ngati ma bore okhazikika, mipata yoziziritsa ma radial, ndi mapewa ofikira - zonse zotsimikizika zapakatikati pogwiritsa ntchito ma Zeiss CMM omwe adasinthidwa kukhala ISO 10360-2. Palibe "kuwunika komaliza kokha." Palibe zongoganizira. Ngati nyumba ya pampu ya pisitoni ikuwonetsa kupatuka kwamamilimita 0.008 kumaso a flange pambuyo pochita nkhanza, timatsatanso mphamvu ya clamping ndi kavalidwe - osadikira mpaka QC yomaliza.
Kuphatikiza uku kumathandizanso mayankho a haibridi. Makasitomala m'modzi waku Southeast Asia amafunikira mbale yoletsa kutupira yokhala ndi zikwama zophatikizika zomangirira ndi machanelo amadzimadzi. M'malo mowotcherera magawo osiyana, timayika maziko mu chitsulo cha ductile (ASTM A), kenako malo osindikizira opangidwa ndi makina a CNC ndi njira zoyendetsera njira imodzi - kuchotsa ma weld 4, macheke 7 a NDT, ndi masabata atatu a nthawi yotsogolera.
Kudalirika Komwe Kutumiza Kumayamba Kale Pamaso Pa Leboti Yotumizira
"Kupereka nthawi" sikukutanthauza kanthu ngati katundu woyamba afika ndi 15% zidutswa chifukwa cha porosity yosazindikirika kapena kuuma kosagwirizana. Timakhazikitsa ma checkpoints atatu osayanjanitsika: kutsimikizira zinthu zomwe zikubwera (spectrometry + tensile sampling), in-process dimensional and metallurgical audit (gawo lililonse la 25), ndi kutsimikizira kwathunthu-kuyesa kukakamiza mpaka 6,000 psi, kusanja kwamphamvu kwa zinthu zozungulira, ndi kutulutsa mchere wopanda zotayira.
Pakuyitanitsa ma prototype, gulu lathu la mainjiniya limawunika momwe zidapangidwira mkati mwa maola 48-osati kungoyang'ana kulolerana, koma kulengeza mikangano ya GD&T yomwe imayambitsa kusokoneza kwa kasinthidwe kapena kusamveka bwino muyeso. Nthawi ina tidagwira kulolerana kwa ± 0.005 mm pa dzenje lakhungu lomwe limafunikira mwayi wofufuza. Kupanganso dongosolo lamadatum kudapulumutsa kasitomala $24,000 mu zida zopanda pake komanso kuchedwa kwa milungu 11.
Makasitomala apadziko lonse lapansi - kuchokera ku OEMs ku Germany kupita kwa ogulitsa Tier-1 ku Texas - amadalira izi. Kuyenda kwathu kowonda kumatsata WIP potengera mtengo, osati dipatimenti. Ngati gawo la cobalt alloy leveler ligunda botolo pakuchiza kutentha, kuwongolera kapangidwe kamene kamasintha kachitidwe ka makina * pamaso pa * mawonekedwe otsalira - osatha.
Leveler Part Factory Imatanthauza Kugwirizana Kwaumisiri, Osati Kungopanga
A zoona leveler gawo fakitale sichiyima pamabokosi otumizira. Imayembekezera mitundu yolephereka: kufalikira kwamafuta osagwirizana pakati pa nyumba yachitsulo ndi mpando wa valve ya cobalt, kuvala movutikira panjira yolumikizira shaft, kunjenjemera panthawi ya msonkhano. Ichi ndichifukwa chake thandizo lathu limaphatikizapo kutsimikizira kujambula, kuwongolera zinthu m'malo mwake (mwachitsanzo, AMS 5387 ikafika pothina), komanso kusanthula kophatikizana kwazomwe zimayambitsa zovuta zikachitika.
Kuyang'ana m'tsogolo, tikuzama R&D munjira zosakanizidwa zopanga makina-makamaka, kuyika ndalama zofananirako zamagulu a cobalt okhala ndi malo opangidwa ndi makina osungidwa mpaka Ra 0.4 µm. Kukula kwa certification kumaphatikizapo AS9100 ya ma leveler-aerospace-critical levelers ndi API Q1 ya ntchito zam'madzi.
Ngati zigawo zanu zolezera ziyenera kupulumuka chifukwa chopanikizika kwambiri, kuvala kwambiri, kutentha kwambiri - ndipo mukufunika kusamveka bwino pamtundu wa zinthu, kubwerezabwereza, kapena kutsimikizika kobweretsa - ndiye kuti kuya kwaukadaulo, kuwongolera koyimirira, ndi kuwongolera zolembedwa sizosankha. Iwo ndiwo maziko. Ndiwo muyezo womwe umamangidwa mugawo lililonse kuchokera ku Qingdao Qiangsenyuan Technology Co., Ltd.
