Kufotokozera Ndi Kusanthula Kwa Crankshaft Manufacturing Technology

Crankshafts amagwiritsidwa ntchito kwambiri mu injini.Pakadali pano, zida zamainjini zamagalimoto ndizomwe zimapangidwira chitsulo ndi chitsulo.Chifukwa cha ntchito yabwino yodulira chitsulo cha ductile, njira zosiyanasiyana zochiritsira zotentha komanso zolimbitsa thupi zimachitidwa kuti apititse patsogolo kutopa, kuuma komanso kukana kwa crankshaft.Ma ductile iron crankshafts ndi otsika mtengo, kotero ma ductile iron crankshafts akhala akugwiritsidwa ntchito kwambiri kunyumba ndi kunja.Pansipa tikuwonetsa ukadaulo wopanga crankshaft.

Ukadaulo wopanga Crankshaft:

1. Ukadaulo woponya wa ductile iron crankshaft

A. Kusungunula

Kupeza kutentha kwambiri, sulfure yochepa, chitsulo chosungunula choyera ndicho chinsinsi chopangira chitsulo chapamwamba cha ductile.Zida zopangira zoweta zapakhomo zimachokera ku cupola, ndipo chitsulo chosungunula sichinakonzedwenso;yachiwiri ndi chitsulo choyera kwambiri cha nkhumba ndi khalidwe losauka la coke.Pakalipano, njira yosungunula yakunja isanakwane desulfurization yakhazikitsidwa, yomwe imagwiritsa ntchito kapu kuti isungunuke chitsulo chosungunula, imayimitsa kunja kwa ng'anjo, kenako imatenthetsa ndikusintha kapangidwe kake mu ng'anjo yolowera.Pakali pano, kudziwika kwa m'nyumba zosungunuka zigawo zachitsulo zakhala zikugwiritsidwa ntchito pogwiritsa ntchito vacuum molunjika kuwerenga spectrometer.

B. Chitsanzo

Njira yopangira mpweya wotuluka mwachiwonekere ndiyabwino kuposa momwe mchenga wadongo umapangidwira, ndipo ma crankshaft castings apamwamba kwambiri amatha kupezeka.Mchenga wopangidwa ndi njirayi umakhala ndi mawonekedwe osasinthika, omwe ndi ofunikira kwambiri pa crankshaft yozungulira.Pakadali pano, ena opanga ma crankshaft ku China adayambitsa njira zopangira mpweya kuchokera ku Germany, Italy, Spain ndi mayiko ena.Komabe, ndi opanga ochepa okha omwe adayambitsa mzere wonse wopanga.

2. Forging teknoloji ya crankshaft yachitsulo

M'zaka zaposachedwa, zida zingapo zopangira zida zapamwamba zidayambitsidwa ku China, koma chifukwa chocheperako, kuphatikiza ndiukadaulo wopanga nkhungu ndi zida zina, zida zina zapamwamba sizinachitepo kanthu.Mwambiri, pali zida zambiri zopangira zakale zomwe ziyenera kusinthidwa ndikusinthidwa.Nthawi yomweyo, ukadaulo wobwerera m'mbuyo ndi zida zikadali pamalo apamwamba, ndipo ukadaulo wapamwamba wagwiritsidwa ntchito koma sunafalikirebe.

3. Makina opangira makina

Pakalipano, mizere yambiri yopangira crankshaft yapakhomo imakhala ndi zida zamakina wamba ndi zida zapadera zamakina, ndipo magwiridwe antchito ndi makina azida ndizochepa.Zida zowononga nthawi zambiri zimagwiritsa ntchito lathe yazida zambiri kutembenuza nyuzipepala yayikulu ya crankshaft ndi khosi, ndipo kukhazikika kwadongosolo kumakhala kovutirapo, ndipo ndikosavuta kupanga kupsinjika kwakukulu kwamkati, ndipo ndizovuta kukwaniritsa zomveka.makinachilolezo.Kumaliza kwanthawi zonse kumagwiritsa ntchito makina opera a crankshaft monga MQ8260 popera movutikira - kutsirizitsa pang'ono - kupukuta bwino - kupukuta, nthawi zambiri pogwiritsa ntchito manja, ndipo mawonekedwe ake ndi osakhazikika.

4. Chithandizo cha kutentha ndi teknoloji yolimbitsa thupi pamwamba

Ukadaulo wofunikira wochizira kutentha kwa crankshaft ndi chithandizo cholimbitsa pamwamba.Ma ductile iron crankshafts nthawi zambiri amakhala okhazikika komanso okonzeka kukonzekera pamwamba.Thandizo lolimbitsa pamwamba nthawi zambiri limagwiritsa ntchito induction harding kapena nitriding.Ma crankshafts opangidwa ndi zitsulo amalembedwa ndikuzunguliridwa.Zida zomwe zatumizidwa kunja zikuphatikiza makina azimitsira a crankshaft a AEG ndi makina ozimitsa a EMA.
