IiCrankshafts zisetyenziswa kakhulu kwiinjini.Okwangoku, izixhobo zeenjini zeemoto ziyi-ductile iron kunye nentsimbi.Ngenxa yokusebenza kakuhle kokusika kwentsimbi ye-ductile, unyango oluhlukeneyo lobushushu kunye nonyango lokomeleza umphezulu lwenziwa ukuphucula amandla okudinwa, ukuqina kunye nokumelana nokunxiba kwe-crankshaft.Iintsimbi ezirhuqwayo zinexabiso eliphantsi, ngoko ke iikrankshaft zentsimbi zisetyenziswa kakhulu ekhaya nakwamanye amazwe.Apha ngezantsi siza kwazisa ubuchwepheshe bokwenza i-crankshaft.
Itekhnoloji yokwenza iCrankshaft:
1. Itekhnoloji yokuphosa ye-ductile iron crankshaft
A. Ukunyibilika
Ukufumana i-high-temperature, i-low-sulfur, isinyithi esibunjiweyo esicocekileyo sisitshixo sokuvelisa i-iron ye-ductile ephezulu.Izixhobo zemveliso yasekhaya zisekelwe ikakhulu kwi-cupola, kwaye isinyithi esityhidiweyo asiyi-desulfurized ngaphambili;eyesibini yintsimbi yehagu ecocekileyo kunye nomgangatho ophantsi wecoke.Okwangoku, i-double-external external pre-desulfurization smelting method yamkelwe, esebenzisa i-cupola ukunyibilikisa isinyithi esinyibilikisiweyo, i-desulfurize ngaphandle kwesithando somlilo, emva koko ishushu kwaye ilungelelanise ukubunjwa kwisithando somlilo.Okwangoku, ukufunyaniswa kwamacandelo esinyithi atyhidiweyo asekhaya aqhutywe ngokubanzi kusetyenziswa i-spectrometer yokufundwa kwe-vacuum ngqo.
B. Ukwenza umzekelo
Inkqubo yokubumba impembelelo yokuhamba komoya ngokucacileyo ingaphezulu kwenkqubo yohlobo lwesanti yodongwe, kunye nokuchaneka okuphezulu kwe-crankshaft castings kunokufumaneka.Isikhunta sesanti esiveliswe yinkqubo sineempawu zokungabikho kwe-rebound deformation, ebaluleke kakhulu kwi-multi-turn crankshaft.Okwangoku, abanye abavelisi be-crankshaft e-China baye bazisa iinkqubo zokubumba impembelelo yomoya ukusuka eJamani, e-Itali, eSpain nakwamanye amazwe.Nangona kunjalo, bambalwa abavelisi abaye bazisa umgca wemveliso wonke.
2. Ubuchwephesha bokwenza i-crankshaft yensimbi
Kwiminyaka yakutshanje, inani lezixhobo zokubumba eziphambili ziye zaziswa eChina, kodwa ngenxa yenani elincinane, elidityaniswe neteknoloji yokuvelisa umngundo kunye nezinye izibonelelo, ezinye izixhobo eziphambili azizange zidlale indima yazo.Ngokubanzi, zininzi izixhobo zakudala ezifuna ukulungiswa kwaye zihlaziywe.Kwangaxeshanye, itekhnoloji yangasemva kunye nezixhobo zisekwindawo ephambili, kwaye itekhnoloji ephucukileyo isetyenzisiwe kodwa ayikasasazeka.
3. Iteknoloji yokulungisa oomatshini
Okwangoku, uninzi lwemigca yokuvelisa i-crankshaft yasekhaya yenziwe ngezixhobo zoomatshini eziqhelekileyo kunye nezixhobo ezikhethekileyo zoomatshini, kwaye ukusebenza kakuhle kwemveliso kunye ne-automation iphantsi.Izixhobo ezirhabaxa ubukhulu becala zisebenzisa i-lathe yezixhobo ezininzi ukujika ijenali ephambili yecrankshaft kunye nentamo, kwaye uzinzo lomgangatho wenkqubo luhlwempuzekileyo, kwaye kulula ukwenza uxinzelelo olukhulu lwangaphakathi, kwaye kunzima ukufezekisa okufanelekileyo.umatshiniisibonelelo.Ukugqitywa ngokubanzi kusebenzisa oomatshini bokusila be-crankshaft njenge-MQ8260 yokusila ngokurhabaxa - ukugqiba-ukugqiba - ukucolwa kakuhle - ukupolisha, ngokuqhelekileyo ngokusebenza ngesandla, kwaye umgangatho wokucubungula awuzinzanga.
4. Unyango olushushu kunye neteknoloji yonyango yokomeleza umphezulu
Itekhnoloji ephambili yonyango lobushushu lwe-crankshaft lunyango lokuqinisa umphezulu.Ii-Crankshaft zentsimbi ziqhelekile kwaye zilungiselelwe ukulungiswa komhlaba.Unyango lokomeleza umphezulu ngokubanzi lusebenzisa ukuqina kwe-induction okanye i-nitriding.Ii-crankshaft zentsimbi ezenziweyo zifakwe kwijenali kwaye zijikelezwe.Izixhobo ezithunyelwa ngaphandle zibandakanya umatshini wokucima i-crankshaft we-AEG kunye nomatshini wokucima i-EMA.
I-Wuxi ikhokela i-Precision Machinery Co., Ltdinikeza abathengi bazo zonke iisayizi ezigqityiweyoiinkonzo zokwenziwa kwentsimbi yesikongeenkqubo ezizodwa.
