I-Hino Fuso Universal Bolt ngasemva

I-1, i-Spheroidizing annealing yeebholiti 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.

I-2, Ukuchithwa kunye nokwehliswa kweebholithi eziphezulu

Inkqubo yokususa ipleyiti ye-iron oxide kwintsimbi ebandayo yentsimbi iyahluba kwaye ihla. Kukho iindlela ezimbini: ukuhla ngoomatshini kunye nokucholwa kweekhemikhali. Ukutshintsha inkqubo yokucholwa kweekhemikhali yentonga yocingo kunye ne-mechanical descaling kuphucula imveliso kwaye kunciphisa ukungcoliseka kwendalo. Le nkqubo yokunciphisa ibandakanya indlela yokugoba, indlela yokutshiza, njl njl. Isiphumo sokuhla silungile, kodwa isikali sentsimbi esishiyekileyo asinakususwa. Ngokukodwa xa umlinganiselo wesikali se-iron oxide sinamandla kakhulu, ngoko ukuhla kwe-mechanical kuchaphazeleka bubunzima bomlinganiselo wentsimbi, isakhiwo kunye nesimo soxinzelelo, kwaye sisetyenziswe kwi-carbon steel wire rods kwi-fasteners yamandla aphantsi. Emva kokuchithwa komatshini, intonga yocingo ye-fasteners ephezulu idlula inkqubo yokukhetha imichiza ukuze isuse zonke izikali ze-iron oxide, oko kukuthi, i-compound descaling. Kwiintonga zocingo lwentsimbi yekhabhoni ephantsi, icwecwe lentsimbi elishiywe kukuhla ngoomatshini linokubangela ukuguga okungalinganiyo kokuyilwa kweenkozo. Xa umngxuma wedrafti yeenkozo unamathela kwiphepha lentsimbi ngenxa yokukhuhlana kwentonga yocingo kunye nobushushu bangaphandle, umphezulu wentonga yocingo uvelisa amanqaku e-longitudinal grain.
