Iyo ba injeniyeri bagaragaje ibishishwa bishushanya ibice byicyuma, ntabwo bategeka gusa gukina-barasaba gusubiramo ibipimo muri mm 0.15 mm, guhuza microstructure guhuza ibice 500+ kg, n'imbaraga zingana zifite munsi ya 350 bar hydraulic pulses. Niyo mpamvu gushakira ukuri shell molding cast ibyuma uruganda ntabwo bijyanye nigiciro-kijyanye na disipuline ya metallurgiki, gukorera mu mucyo, no kwihanganira zeru kuri grafite nodule ihinduka.
Impamvu Igikonoshwa gitanga aho umusenyi utemba ugufi
Twabonye imishinga myinshi inanirwa kuko amakipe yatekerezaga "guta ibyuma" bisobanura "guhinduranya." Ntabwo aribyo. Mubitutu byamazu yububiko cyangwa piston pompe ya silinderi, morphite ya grafite igenzura ubuzima bwumunaniro. Igishushanyo mbonera gitanga igipimo cyo gukonjesha - ni ingenzi kubwoko bwa A flake grafite hamwe no gukwirakwiza kimwe. Bitandukanye nicyatsi kibisi-umucanga, ibishishwa bikoresha fenolike resin-isize silika umucanga wakize kuri 230 ° C. Igisubizo? Ubuso burangije Ra ≤ 6.3 µm, inguni zingana munsi ya 0.5 °, nubugari bwurukuta bugenzura kugeza kuri mm 4,5 nta guhinduranya ingirakamaro. Dufata buri gihe guhamagarwa kwa GD&T nko kwihanganira imyanya Ø0.05 mm kuri 12-mm-ya diametre ya dowel-nta mashini ya kabiri.
Kwishyira hamwe Vertical Ntabwo ari Buzzword-Nukugabanya ibyago byawe
Bamwe mubatanga isoko yo gushonga, gukora ibumba, no gutunganya ibicuruzwa bitandukanye. Ibyo birema ingingo eshatu zo kunanirwa gukurikiranwa, ibintu bitatu byo gukuramo ibipimo, hamwe nuburyo butatu bwo kuvura ubushyuhe budahuye. Kuri QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD., Itsinda rimwe rigenzura urunigi rwuzuye: icyemezo cyibikoresho fatizo (ASTM A48 Icyiciro cya 35/45, EN-GJL-250), umusaruro wibishishwa, 1,480 ° C cupola + induction duplex gushonga, CNC ikora kuri DMG MORI NTX 1000s. Mugihe umukiriya wumunyaburayi yari akeneye ibice 270 byacometse kuri cobalt-alloy hamwe na AMS 5387 yubahiriza, twakoresheje isesengura ryashonga kuri buri cyiciro, twandika ikirere cy’itanura O₂ urwego nyarwo, kandi twashushanyije ikarita ya gradients kuri buri gice - kubera ko gutandukana kwicyiciro bisobanura ibyumweru 12 byo gutaha kumurima.
Aho Cataloge isanzwe irangirira - Ibisabwa byawe Bitangiye
Urwego rusanzwe rwicyuma ntirukemura ibibazo nko kwambara nabi muri winch center shaft rollers cyangwa gusiganwa ku magare mu mavuta na gazi pompe. Niyo mpamvu akazi kacu gatangira mbere yuburyo: gusuzuma inzira zawe zikorera imitwaro, kumenya guhangayikishwa cyane na FEA mbere yo kwemeza, no guhitamo ibivanze shingiro bihuye na serivise - ntabwo ari umutwe wamakuru. Kubisabwa kwambara cyane, duhindura karubone ihwanye na (CE) kuri 3.1–3.3 hanyuma twongereho 0,25% Cu kugirango tunonosore umwanya wa pearlite. Kubintu bihindagurika cyane, dukoresha inoculants hamwe na Ba-Ca-Si kugirango duhagarike ubukonje. Kandi yego - twanditse ibyemezo byose mubipapuro bya PPAP, harimo raporo yisesengura ryerekana hamwe nubunini bwimbuto kuri ASTM E112.
- Imyanda: Yakozwe muri ASTM A278 Icyiciro cya 65-45-12 icyuma cyumubyimba, nyuma yubushyuhe buvuwe kugeza 220-240 HBW
- Inzu ya pisitori ya pompe: Shell-molded EN-GJS-400-15 with machined bores held to ISO IT6
- Imashini yubwubatsi winch shafts: T800 cobalt-ishingiye kuri alloy casting hamwe no kugenzura gukomera
- Amajwi adasanzwe: AMS 5387 cobalt ivanze, igisubizo-gishyizwe kuri 1,175 ° C ± 5 ° C, hanyuma kizimya amazi
Baza ibi bibazo bitanu mbere yuko utanga PO
Ntabwo inganda zose zikora ibishishwa zikora kurwego rumwe. Baza uwaguhaye isoko:
- Urashobora gutanga impapuro zishonga zerekana ubushyuhe bwa salle, ibice bya slag, hamwe nigihe cyo gutera inshuro eshatu zanyuma?
- Ni ubuhe bushobozi bwawe ntarengwa bw'uburemere-kandi nigute ushobora kugenzura ubunyangamugayo kubice birenga mm 120 z'ubugari?
- Ukora ibizamini bya ultrasonic kuri casting zose> kg 50, kuri ASTM E186?
- Nigute ushobora kwemeza ubukana bwubuso hagati ya Brinell na Rockwell kubice bivura ubushyuhe?
- Ese ISO 9001: 2015 yerekana icyemezo cyihariye cyo gushushanya ibicuruzwa no gutunganya neza - cyangwa "gukora rusange"?
Niba ibisubizo bidasobanutse cyangwa byatinze, genda. Gutora neza bisaba kubazwa neza.
QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD. ikora nka a shell molding cast ibyuma uruganda aho aba metallurgiste basubiramo ibishushanyo hamwe nabakanishi - kandi aho buri cyerekezo cyo kuvura ubushyuhe cyinjiye, buri iperereza rya CMM rihinduka buri munsi, kandi ibyoherejwe byose birimo ibintu byose bikurikirana kugeza kuri numero ya inot. Ntabwo twohereza ibice. Kohereza amabahasha yagenzuwe neza. Kuri sisitemu ya hydraulic isunika akabari 400, kuri pompe zo hanze zikora amasaha 20.000 nta kuvugurura, kubinyabiziga byubwubatsi bikora -40 ° C imiterere ya Arctique-itandukaniro ntabwo riri mumpapuro zabigenewe. Ari muri node, imbibi zingano, nibyemezo byanditse byafashwe mbere yo gusuka bwa mbere.
