Ingcaciso yeMveliso
Iibholiti zeHub ziibholiti eziphakamileyo ezidibanisa izithuthi kumavili. Indawo yoqhagamshelo yiyunithi yehabhu ethwele ivili! Ngokuqhelekileyo, iklasi ye-10.9 isetyenziselwa izithuthi ezincinci, iklasi ye-12.9 isetyenziselwa izithuthi ezinkulu! Ubume be hub bolt ngokuqhelekileyo yifayile yesitshixo eneknurled kunye nefayile enemisonto! Nentloko yomnqwazi! Uninzi lweebholiti zesondo ezimile okwe-T zingaphezulu kwe-8.8 grade, ethwele unxibelelwano olukhulu lwe-torsion phakathi kwevili lemoto kunye ne-asi! Uninzi lweebholithi ezinentloko ephindwe kabini zingaphezulu kwebanga lesi-4.8, ezithwele unxibelelwano olukhaphukhaphu phakathi kweqokobhe lehabhu yevili elingaphandle kunye netayara.
Inkqubo yokuvelisa iibholiti zamandla aphezulu
1. I-Spheroidizing annealing yeebholithi zokuqina okuphezulu
Xa i-hexagon socket bolts iveliswa yinkqubo yesihloko esibandayo, isakhiwo sokuqala sentsimbi siya kuchaphazela ngokuthe ngqo ukukwazi ukwenza ngexesha lokubanda kwesihloko. Ngoko ke, intsimbi kufuneka ibe neplastiki elungileyo. Xa ukubunjwa kweekhemikhali zentsimbi zihlala zihlala, isakhiwo se-metallographic sisona sizathu esibalulekileyo sokugqiba iplastiki. Ngokuqhelekileyo kukholelwa ukuba i pearlite erhabaxa erhabaxa ayihambisani nokwakheka kwesihloko esibandayo, ngelixa iperile entle engqukuva inokuphucula ngokubonakalayo isakhono sentsimbi yeplastiki.
Kwintsimbi yekhabhoni ephakathi kunye nentsimbi yealloyi yekhabhoni enesixa esikhulu sezinto zokuqinisa amandla aphezulu, i-spheroidizing annealing yenziwa ngaphambi kwesihloko esibandayo, ukuze kufumaneke iyunifomu kunye nepearlite ecolekileyo ye-spheroidized ukuhlangabezana ngcono neemfuno zokwenyani zemveliso.
