Ikhwalithi ephezulu ye-ISUZU NKR Rear Hub Bolt

1.I-Spheroidizing annealing yamabhawodi anamandla amakhulu

Lapho amabhawodi ekhanda lesokhethi ye-hexagon ekhiqizwa inqubo yesihloko esibandayo, ukwakheka kwangempela kwensimbi kuzothinta ngqo ikhono lokwakha ngesikhathi sokucutshungulwa kwesihloko esibandayo. Ngakho-ke, insimbi kufanele ibe nepulasitiki enhle. Lapho ukwakheka kwamakhemikhali ensimbi kuhlala njalo, ukwakheka kwe-metallographic kuyisici esibalulekile esinquma ipulasitiki. Ngokuvamile kukholakala ukuthi i-pearlite egqagqene egqagqene ayihambisani nokwakheka kwesihloko esibandayo, kuyilapho i-pearlite eyisiyingi ecolekile ingathuthukisa ngokuphawulekayo ikhono lokuguga lepulasitiki lensimbi.
Ngensimbi ye-carbon steel ne-medium carbon alloy steel enenani elikhulu lezibophelelo ezinamandla amakhulu, ukufakwa kwe-spheroidizing annealing kwenziwa ngaphambi kwesihloko esibandayo, ukuze kutholwe i-pearlite efanayo nenhle ye-spheroidized ukuze kuhlangatshezwane kangcono nezidingo zangempela zokukhiqiza.

Umdwebo we-2.high-strength bolt

Inhloso yenqubo yokudweba ukuguqula usayizi wezinto zokusetshenziswa, futhi okwesibili ukuthola izakhiwo eziyisisekelo zemishini ye-fastener ngokusebenzisa ukuguqulwa nokuqinisa. Uma ukusatshalaliswa kwesilinganiso sokunciphisa kokudlula ngakunye kungafanelekile, kuzophinde kubangele ukuqhekeka kwe-torsional ocingweni lwenduku yocingo ngesikhathi senqubo yokudweba. Ukwengeza, uma ukugcoba kungalungile ngesikhathi sokudweba, kungase futhi kubangele ukuqhekeka okujwayelekile okuguquguqukayo endongeni yocingo oludonswe ngokubanda. Ukuqondiswa kwentambo yentambo kanye nomdwebo wentambo kuyafa ngesikhathi esifanayo lapho intambo yocingo igingqika iphuma emlonyeni wentambo ye-pellet ayigxili, okuzokwenza ukuguga kwephethini yembobo ehlangene yomdwebo wocingo kuthuthuke. , futhi imbobo yangaphakathi izobe ingaphandle kwendilinga, okuzoholela ekuguqulweni komdwebo okungalingani ekuqondeni kwe-circumferential yocingo, okwenza ucingo I-roundness iphelelwe ukubekezelelana, futhi ukucindezelwa kwe-cross-sectional kocingo lwensimbi alufani ngesikhathi kubanda. inqubo yesihloko, ethinta izinga lokuphasa kwesihloko esibandayo.
