I-crankshaft "ngumqolo" we-injini, echaza ngokuthe ngqo amandla, ixesha lokuphila, kunye nokuthembeka kombindi wamandla. Ukumelana neemeko zokusebenza ezigqithisileyo, sisebenzisa ulawulo olungqongqo kwimathiriyeli kunye nayo yonke inkqubo yokubumba kwasekuqaleni-ukuqinisekisa ukuba yonke i-crankshaft forging yakhiwe nge-DNA ephezulu.
1. UKhetho lweMathiriyeli ePhakamileyo: Isiseko esomeleleyo esivela kuMthombo
Siyaqonda ukuba izinto eziphathekayo zisisiseko sokusebenza. Ngaphaya kweentsimbi ze-alloy eziqinisekisiweyo ezifana ne-42CrMoA, sisebenzisa ngokusebenzayo iintsimbi ezingacimiyo nezinobushushu (microalloyed) ezifana ne-49MnVS3 kunye ne-48MnV. Ngokulawulwa kokupholisa emva kokupholisa, ezi zintsimbi zifezekisa iipropati ezifunekayo ngaphandle kokunyanzeliswa kwe-energy-intensive, ukuphazamiseka-okubangelwa ukushisa kwamabakala endabuko-ukunyusa ukusebenza kakuhle, ukusika iindleko, kunye nokuqinisekisa ukuzinza kwe-dimensional kunye nokuhambelana.
Imigangatho yethu yangaphakathi yempahla ekrwada iyodlula lee imimiselo yoshishino, enemida engqongqo kwizalathisi eziphambili zobomi bokudinwa ezifana nobunyulu, ubungakanani beenkozo, kunye nokwakheka kweebhanti. Zonke izixhobo zivela kubaboneleli beqhinga abaqinisekisiweyo phantsi kwenkqubo emibini yesivumelwano sobugcisa kunye nokuhlolwa kwakhona okungenayo, ukuphelisa umngcipheko kumthombo.
2. Inkqubo enguNdoqo: UkuCwangcisa ukuCwangcisa ukomelela kunye nokuqina
Ii-crankshafts eziphakamileyo kufuneka zisebenzise iindawo ezingenanto-ezingazange zenziwe ngokuthe ngqo kwi-bar stock-ukuqinisekisa ukuhamba okuziinkozo kwentsimbi okuqhubekayo kunye neempawu ezifanelekileyo zoomatshini.
Ukuqulunqwa okuchanekileyo: Ukubumba okudityanisiweyo kokufa kunye ne-RR / TR ephazamisayo ye-crankshafts enkulu ifezekisa ukubunjwa kwenetha okuchanekileyo kumsebenzi omnye kumatshini wokushicilela onzima. I-closed-die forging isetyenziswa ngokubanzi kwimveliso yomthamo ukwandisa ukusetyenziswa kwezinto eziphathekayo.
Ulawulo lobushushu obuchanekileyo: Ukufudumeza okungena-oxidation kuyo yonke indawo kuthintela ukubola komphezulu, kunye nolawulo olukrelekrele lokuqala nokugqiba amaqondo obushushu angaphakathi kwi-± 15 ° C kumgangatho ongaguqukiyo.
Ukusebenza okulungiselelweyo: Sisebenzisa ukuhlukana kwe-post-processing ngezinto eziphathekayo-ukufikelela kwi-microstructure efanelekileyo kwiintsimbi ezingacinywanga ngokupholisa okulawulwayo, kunye nokusebenzisa i-standard standardized and quenching-and-tempering to quenching-and-tempering to alloy steels, kunye nokubekwa ngokucophelela kulo lonke ukunciphisa ukuphazamiseka.
3. Uhlolo olungqongqo: IziKhuseli ezininzi, ukuhanjiswa okungenaxhala
Yonke inkohliso kufuneka idlule inkqubo yethu yokuhlola epheleleyo ngaphambi kokukhululwa.
I-100% yoVavanyo olungonakalisiyo: I-crankshaft nganye ihlola i-ultrasonic kunye ne-magnetic particle inspection, ihlolisise iziphene zangaphakathi kunye neendawo eziphezulu kunye neendawo ezingaboniyo zero ukuqinisekisa ukuxinwa kwangaphakathi kunye nomgangatho ongenasiphako.
Ukuqinisekiswa okugunyazisiweyo: Yonke imveliso kunye nolawulo lomgangatho luhambelana nemigangatho yamva nje yoshishino, kuquka i-CB /T 4313-2013. Kwiicrankshafts zaselwandle, sinikezela ngesatifikethi esipheleleyo esiquka imibutho elishumi ephambili yokuhlelwa (CCS, DNV, ABS, LR, kunye nokunye)—ukuxhasa iimveliso zakho kwihlabathi liphela ukusuka kuhlolo olungenayo ukuya ekuvunyweni kokugqibela.
Sikhethe, kwaye ukhetha:

Izinto zokusika kunye nolawulo olungqongqo lwemithombo
Iinkqubo zokubumba ezikwinqanaba eliphezulu kunye nolawulo lwenkqubo echanekileyo
Inkqubo yokuhlola epheleleyo kunye nesiqinisekiso esigunyazisiweyo

Sihambisa izisombululo ezidibeneyo-ukusuka kwi-crankshafts ekumgangatho ophezulu ukuya kwiinkonzo zesatifikethi ezibanzi-ukubonelela ngesiseko esiqinileyo sentliziyo eyomeleleyo, ethembekileyo ye-injini.
