Zvikamu zvesimbi zvekukanda hazvingomirire zvinorema-basa maindasitiri nharaunda-zvinotsanangura kuvimbika kana kutadza isiri sarudzo. Takaona mavharuvhu ekumanikidza achipwanyika pasi pekuchovha bhasikoro, pombi yepiston pombi inoputika mushure memwedzi gumi nemisere iri mumusha weoiri sevhisi, uye winch centre shaft rollers inobata pakati-inosimudza pane vanochera migodhi. Kukundikana kwega kwega kunodzokera kune chimwe chikonzero: hunhu hwenyama husingaenderane nechaiyo-nyika yekushushikana profiles. Ndosaka zvikamu zvesimbi zvakakandwa-kunyanya izvo zvakagadzirirwa kugadzikana kwedimensional, microstructural consistency, uye functional metallurgy-zvinoramba zvisingadzoreki muhydraulic system, mota dzeinjiniya, uye yakakwirira-kutendeseka pombi magungano.
Nei Zvikamu zveSimbi zveCast zvichipfuura dzimwe nzira muMishinari-Yakakosha Mabasa
Forged simbi inopa simba, asi inoshaya yakaoma yemukati geometry. Zvigadzirwa zvakashongedzwa zvinounza nzvimbo dzakakanganiswa nekupisa dzinokanganisa hupenyu hwekuneta. Mabheti akagadzirwa anorasa 60–75% yezvinhu mbishi-uye kunetseka nekusiyana kwemadziro kwakasiyana-siyana kunowanikwa mumiviri yevharuvhu kana silinda dzimba. Zvikamu zvesimbi zvakakandwa zvinogadzirisa iyi katatu yezvisingakwanisi. Kukandwa kwejecha kunopa pedyo-mambure zvimiro zvezvikamu zvakakura, zvakakora-chikamu senheyo dzepombi; kukanda kwekudyara kunosvika ± 0.05 mm kushivirira pane dzakatetepa-yakavezwa cobalt alloy nozzles. Zvine hutsinye, iyo yekusimbisa maitiro inobvumira inodzorwa zviyo chimiro kurongeka-kunyanya kukosha muAMS 5387 cobalt alloy 6 pombi zvikamu uko kutonhora kwakananga kunodzivirira kutsemuka kwepakati panguva yekukwira-kutenderera kwekumanikidza.
Isu tinogara tichiyedza zvikamu zvesimbi zvakakandwa zvinopesana nematanho matatu ekushanda: Thermal shock resistance inopfuura 400°C, Kukukurwa kwevhu kuri pasi pe 0.08 mm/gore mune abrasive slurry,uye kuneta hupenyu hunodarika 10⁷ cycles pa85% goho kushushikana. Chete yakanyatso batwa kupisa-yakagadziriswa ASTM A216 WCB kana ASTM A351 CF8M castings inosangana ese ari matatu. Dzimwe nzira dzemutengo wakaderera dzinotadza kufanofungidzira-kwete pakutanga, asi pamwedzi gumi nemana, apo microcracks nucleate pa shrinkage porosity nzvimbo dzisingaonekwe kune yakajairwa UT kuongororwa.
Mutengo Wakavanzika we "Zvakanaka Zvakakwana" Kusarudzwa kwezvinhu
Vamwe vatengi vanotsanangura "cast steel" pasina kutsanangura giredhi, kupisa kurapwa, kana NDT zvinodiwa. Takatumira mazana maviri nemakumi maviri mayunitsi eT800 cobalt-based center shaft roller kuEuropean OEM-kuzongogamuchira chiziviso chekuyeuka mavhiki matanhatu gare gare. Root cause? Mutengesi wavo akatsiva ASTM A487 Giredhi CA15 yeT800 pasina mvumo. Zvose zviri martensitic Stainless steels-asi CA15 ine 12% Cr versus T800's 27% Cr + 5% Mo. Mhedzisiro: chloride pitting mumvura yegungwa-yakatonhorera winch gearboxes. Corrosion inotangwa pamakining mamaki akasiiwa neakadzikama tooling, inokwidziridzwa nekusara kwekunetsekana kubva kune isina kufanira post-weld annealing.
Izvi hazvisi dzidziso. Ndosaka isu tichimanikidza mana asina kutaurirana chekutarisa: certified mill test report kune ese anopisa, yakananga spectrographic analysis pamabhawa anouya, solidification simulation pamberi pekugadzira mold,uye yakazara-chikamu kuomarara mepu pane akapedza castings. Hapana kunze - kunyangwe kune prototypes. Vatengi vanodarika nhanho idzi vanobhadhara 3.2 × yakawanda mukukundikana kwemunda pane kumberi kwezvinhu kusimbiswa.
Manufacturing Control Inotangira Pamberi Kudurura
Kuita kwechokwadi kunotanga mune yekutanga - asi kunowedzera kuburikidza nekugadzira, kupisa kupisa, uye kupedzisa. Isu tinosanganisa jecha kukanda neshanu-axis CNC machining mune imwe kuyerera kwekushanda: dzimba dzakakandwa dzinoenda dzakananga kubva ku shakeout kuenda kuchoto chekuyamura, tozoenda kune dzakachinjika zvigayo zvinobhowa zvinobata ± 0.015 mm chinzvimbo chekushivirira pakutakura mabhora. Izvi zvinobvisa zvikanganiso zvekugadzirisa zvakare zvinotambudza vatengesi vachishandisa vakasiyana kukanda uye machining vatengesi. Kune zvikamu zveAMS 5387, tinoita mhinduro annealing pa 1150 ° C ichiteverwa nekudzima nekukurumidza- tobva takura pa800 ° C kwemaawa gumi nematanhatu. Nhanho imwe neimwe yakadhindwa, inoteedzerwa kuvira batch ID uye thermocouple chiteshi.
Yedu ISO-inoenderana nzvimbo inomhanyisa CMM yekuongorora pa100% yezvinhu zvakakosha: chigaro chinonangana pamavharuvhu ekumanikidza, bore cylindricity pane piston pombi housings, uye pamusoro pekupedzisira pamusoro roller kuonana nzira (Ra ≤ 0.4 µm). Isu tinoramba castings inoratidza > 0.15% carbide segregation mu microstructure scans-kunyangwe vakapfuura dimensional cheki. Nekuti kuvimbika hakuyerwe mumamicrons chete. Iri mukufanana kwekugoverwa kwechromium pamuganhu wese wezviyo.
Kusarudza Cast Steel Parts Inoendesa-Kwete Kungozivisa-Kuita
Bvunza mibvunzo iyi usati wapedzisa chero mutengesi: Chitupa chavo chemidziyo chinovhara kemikari yakagadzirwa *uye* michina zvivakwa pakupisa here? Ivo vanoita ultrasonic bvunzo pa100% yeakakwira-kudzvanywa dzimba-kana chete sampuli mijenya? Vanogona here kupa microstructure mishumo inoratidza dendrite ruoko spacing uye kuisirwa chiyero pane ASTM E45? Kana mhinduro iri "kwete" kune chero ipi zvayo, uri kutenga zvinyorwa-kwete inshuwarisi.
QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD. inovaka simbi dzakakandwa mativi einjiniya akatsiva imwe vharafu katatu. Tarisiro yedu inoramba yakamanikana: hydraulic control system, oiri & gasi kuyerera midziyo, injiniya mota powertrain zvikamu, uye specialized pombi maassemblies anoda cobalt-nickel alloys, T800-giredhi zvinhu, kana chaiyo stainless castings. Isu hatidzingire volume. Isu tinoinjiniya kudzokorora-kupfuura mazana mashanu-mabhechi, mukati memakore gumi nemaviri masevhisi, mhiri -40°C Arctic deployments uye 500°C yekunatsa manifolds akawanda.
Zvikamu zvesimbi zvinobudirira kana metallurgy inosangana nemishoni. Kwete kana mafungidziro achitaridzika zvakanaka pabepa-asi kana chikamu chakabata kudzvanywa pa350 bar ichitenderera pa1,800 rpm, gore negore. Ndiwo chiyero chatinogadzira, kukanda, muchina, uye certification kune-nguva imwe neimwe.
