WELONG shaft forgings zazikulu za hydro-jenereta

Zida Zopangira:

20MnNi ndi 20MnNi.

Katundu Wamakina:

Pa makulidwe a forging (T) pakati pa 300mm <T ≤ 500mm, zinthu 20MnNi ziyenera kukhala ndi mphamvu zokolola ≥ 265MPa, mphamvu zamakokedwe ≥ 515MPa, elongation pambuyo kuthyoka ≥ 21%, kuchepetsa dera ≥ 35 ≥ ≥ 35% mphamvu, mphamvu ) ≥ 30J, ndipo palibe ming'alu panthawi yozizira.

Kwa makulidwe a forging (T) wamkulu kuposa 200mm, zinthu 25MnNi ziyenera kukhala ndi mphamvu zokolola ≥ 310MPa, mphamvu zamakokedwe ≥ 565MPa, elongation pambuyo kusweka ≥ 20%, kuchepetsa dera ≥ 35%, mphamvu mayamwidwe 0≥3 (0≥3) , ndipo palibe ming'alu panthawi yozizira.

Kuyesa Kosawononga:

Njira zosiyanasiyana zoyesera zosawononga monga kuyesa kwa ultrasonic (UT), kuyesa kwa maginito (MT), kuyezetsa kwamadzimadzi (PT), ndi kuyang'ana kowona (VT) ziyenera kuchitidwa m'magawo osiyanasiyana a shaft forging pagawo ndi mikhalidwe yosiyanasiyana. . Zinthu zoyesera ndi njira zovomerezera ziyenera kutsata miyezo yoyenera.

Chithandizo cha Chilema:

Zowonongeka kwambiri zimatha kuchotsedwa pogaya mkati mwa machining allowance range. Komabe, ngati kuya kwa chilema kupitirira 75% ya malipiro omaliza, kukonza kuwotcherera kuyenera kuchitika. Kukonza zolakwika kuyenera kuvomerezedwa ndi kasitomala.

Maonekedwe, Dimension, ndi Surface Roughness:

Njira yopangira jekeseni iyenera kukwaniritsa zofunikira za dimensional ndi pamwamba zomwe zafotokozedwa muzojambula. M'kati mwa bwalo lamkati mwaukali (mtengo wa Ra) wa kupangirako uyenera kukonzedwa ndi wogulitsa kuti akwaniritse 6.3um.

Kusungunula: zitsulo zachitsulo zopangira zitsulo ziyenera kupangidwa kudzera mu ng'anjo yamagetsi yosungunuka ndikuyengedwa kunja kwa ng'anjoyo isanayambe kuponyera vacuum.

Kupanga: Ndalama zokwanira zodula ziyenera kuperekedwa kumapeto kwa sprue ndi nsonga zachitsulo. Kupanga kuyenera kuchitidwa pamakina osindikizira okhoza kuwonetsetsa kuti pulasitiki yokwanira pagawo lonse la forging. Ndikoyenera kukhala ndi chiŵerengero cha forging choposa 3.5. Kupanga kuyenera kuyandikira kwambiri mawonekedwe omaliza ndi miyeso, ndipo mizere yapakati ya injot ndi chitsulo ingot igwirizane bwino.

Kuchiza Kutentha kwa Zida: Pambuyo popanga, kufota kuyenera kutenthedwa kapena kutenthetsa ndi kutenthetsa kuti apeze mawonekedwe ndi katundu wofanana. Kutentha kocheperako sikuyenera kutsika 600 ° C.

Ngati mukufuna zambiri za WELONG forgings za zida zazikulu ndi mphete zamagiya, chonde tidziwitseni.
