Umbani wokubhoboza isisila esinezinhlangothi ezine ezinephedi ozithephayo, isikulufu sensimbi sethayela lensimbi isikhonkwane sokubhoboza isipikili isikulufu seCorner drill tail

Uma ungakwazi kuqala ukuqonda izakhiwo zemishini yezikulufa lapho uzisebenzisa, khona-ke ungazisebenzisa kangcono. Izinhlobo ezihlukene zezikulufi zinezinto zokuwumshini ezihlukile, futhi izici ezihlukene zokuwumshini ziphumela ezikhathini ezihlukene lapho kusetshenziswa khona izikulufu. 1, Izikulufu zokuzithepha ngokwakho: Izidingo zokusebenza kwemishini 1. Ukuqina okuyinhloko: inani elijwayelekile HRC28-38. Lapho uhlola, thatha isigaba izikhathi ezingu-1-2 ubukhulu obujwayelekile ukusuka emsileni. Uma ubude begama bufushane kakhulu, bungashumeka kuqala bese ubulukhuni bungalinganiswa. 2. Ukuqina kobuso: Okujwayelekile MIN HV450. 3. Isendlalelo se-Carbonized: Standard 4 # -6 #: 0.05-0.18mm, 8 # -12 #: 0.10-0.23mm, 14 #: 0.13-0.28mm. Inhloso eyinhloko ye-carburization ukuthuthukisa ubulukhuni bobuso nokuqinisekisa amandla amazinyo. Uma i-decarburization ijule kakhulu futhi i-carburization inganele, amandla amazinyo ngeke ahlangabezane nezidingo, okusho ukuthi amazinyo azolimala ngesikhathi sokuhlolwa kwesikulufa. 4. I-torque: Izincazelo ezijwayelekile 4 # 5 # 6 # 7 # 8 # 10 # 12 # 14 # Amazinyo 14212835455696145AB amazinyo 142128354565102165. 5. Isikulufu esivivinyweni: Khipha ipuleti lensimbi elinesikulufu sokuhlola isikulufu. Isikulufu esizithephayo kufanele sakhe uchungechunge olufanayo kupuleti lokuhlola, futhi uchungechunge lwesikulufu ngokwalo akufanele lulobe noma lonakaliswe kuze kube yilapho intambo ye-taper yokugcina idlula ngokuphelele kupuleti lokuhlola. Isikulufu esivivinyweni sisebenza kuphela kuzikulufu zokuzithinta ngokwakho zezinhlobo ezingu-AB, B, BP, njll. Ngokwemithetho ye-IFI, ipuleti lokuhlola kufanele lilungiswe ngensimbi egoqelwe kancane enekhabhoni ebandayo enokuqina kwe-Rockwell okungu-70-85HRB. Ukucaciswa okujwayelekile kwamapuleti ensimbi, okuhlanganisa ukujiya, kukhonjisiwe kuthebula elingezansi. Izimbobo zokuhlola kufanele zibhodlozwe noma zibhojwe, ngokubekezelela okungu-± 0.025mm kububanzi obuncane obushiwo (bona ithebula elingezansi). Ukucaciswa 6 # 7 # 8 # 10 # 12 # 1/4 test plate ukujiya (mm) 1.85-1.953.12-3.234.68-4.84 ukuvula (mm) ± 0.0252.953.263.454.044.765.50.
