I-Induction yokufudumeza iziko lokubumba i-crankshaft

Ukuze kuphuculwe umgangatho wendalo wecrankshaft, iplanti yokuvelisa icrankshaft isebenzisa ifiber egcweleyo yokwenza inkqubo yecrankshaft. Ukufudumeza ngaphambi kokwenza i-forging isoloko isebenzisa isithando somlilo segesi yendalo ukufudumeza kwendawo. Ngenxa yexesha elide lokufudumeza, i-crankshaft ineenkozo ezinkulu zekristale, izikali ze-oxide ezingaphezulu, kunye nokusetyenziswa kwegesi yendalo enkulu. Inkcitho yamandla iyingozi. Ukuze utshintshe iteknoloji yemveliso ephelelwe lixesha kunye nezixhobo, iplanti yokuvelisa i-crankshaft indulule ukusebenzisa i ukufudumeza iziko ukwenza i-crankshaft ngayo yonke ifayibha, ngoko ke iseti yesixhobo sokufudumeza esifudumezayo sokufudumeza inxalenye yecrankshaft yayilwa yaze yenzelwe ukuba isetyenziswe kwiplanti yemveliso.

Ubume kunye nobukhulu bendawo yokufudumeza indawo ye-crankshaft iboniswe kwi-Figure 12-96, ubuninzi bedayamitha yangaphandle yi-Φ310mm, ubude bendawo yokufudumeza yi-Φ580mm, izinto ze-crankshaft yintsimbi ye-alloy, ubushushu bokufudumala yi-1200. ℃, umahluko wobushushu beradial awukho ngaphezulu kwe-100 ℃, kwaye ixesha lokufudumeza yi-20mino.

Umfanekiso 12-96 Crankshaft

I-intermediate inductor ephakathi esetyenziselwa ukufudumeza kwendawo ye-crankshaft yinqanaba elinye, kwaye i-conductor magnetic eyenziwe ngamashiti ensimbi ye-silicon icwangciswe malunga ne-coil induction. Ikhoyili inxeba kunye nomngxuma ojikelezayo eccentric ityhubhu yobhedu ecocekileyo 30mm x 15mm / 10mm X 2mm, kwaye ityhubhu yobhedu esulungekileyo inxeba. Kukho iiribhoni zeglasi ezingena-alkali, ezifakwe ivanishi kwaye zomisiwe. Ikhoyili ye-induction ixinzelelwe ngesixhobo sokunyanzeliswa kwentwasahlobo ukuphepha ukungcangcazela ngexesha lokusebenza. I-terminal voltage ye-inductor yi-500V, amandla angama-500kW, kwaye amandla afakiweyo angama-800kW. Inkqubo yokunikezelwa kwamandla inqanaba lesithathu, kwaye umthwalo wesigaba esisodwa ulungelelaniswa kwinqanaba lesithathu kunye ne-capacitors kunye ne-reactors.

Ngokolwazi lomnye umenzi we-crankshaft, i-diameter yangaphandle ye-crankshaft yi-Φ200mm, ubude bendawo yokufudumeza yi-420mm, iqondo lokushisa lokufudumeza yi-1200℃, kwaye umahluko wobushushu be-radial yi-125 nanye. Ubungakanani bengqolowa ye-crankshaft eyenziwe ngokufudumeza kwegesi yendalo yi-4-5 emva kokuba unyango lokuqala lobushushu (ngaphantsi kwe-4 alufanelekanga), i-crankshaft eyakhiwe yi-furnace yokufudumeza induction, ubungakanani bengqolowa yi-5 emva konyango lokuqala lokushisa -6 ibakala; inqanaba lemfundo ye-micro forging ye-crankshaft yexesha elinye yi-77% yokufudumala kwesithando segesi yendalo kunye ne-95% yokufudumeza okuphakathi kwamaza okufudumeza; Ubuninzi be-curvature ye-crankshaft (phambi kokulungiswa) yi-30mm yokufudumala kwesithando segesi yendalo kunye ne-15mm yokufudumala kwesithando sokufudumala; Ukusetyenziswa kwamandla okufudumeza kwe-Crankshaft (iguqulwe ibe ngamalahle aqhelekileyo), ukusetyenziswa kwamandla okufudumeza kwegesi yendalo yi-2018kg / iqhekeza, kunye nesithando sokufudumala sokufudumala. ukusetyenziswa kwamandla yi-154kg / iqhekeza. Ke ngoko, ukufudumeza kwe-crankshaft phambi kokwenziwa kwe-forging kutshintshwa ukusuka kwigesi yendalo yokufudumeza kwiziko lokufudumeza lokungenisa, eliphucula umgangatho wemveliso, licuthe ukusetyenziswa kwamandla, kwaye lineenzuzo ezicacileyo zoqoqosho. Kwangaxeshanye, imeko yokusebenzela iyaphuculwa kwaye noxinzelelo lwabasebenzi luyancitshiswa.
