Zoo siab ISUZU NKR Tsheb Hub Bolt

1.Spheroidizing annealing ntawm high-strength bolts

Thaum lub hexagon socket taub hau bolts yog tsim los ntawm cov txheej txheem txias taub hau, cov qauv qub ntawm cov hlau yuav ncaj qha cuam tshuam rau kev tsim muaj peev xwm thaum lub caij txias ua haujlwm.Yog li ntawd, cov hlau yuav tsum muaj cov yas zoo.Thaum cov tshuaj muaj pes tsawg leeg ntawm cov hlau tsis tu ncua, cov qauv metallographic yog qhov tseem ceeb ntawm kev txiav txim siab plasticity.Nws feem ntau ntseeg hais tias cov ntxhib flaky pearlite tsis yog qhov tsim nyog rau lub taub hau txias, thaum lub ntsej muag zoo nkauj pearlite tuaj yeem txhim kho lub peev xwm ntawm cov yas deformation ntawm cov hlau.
Rau nruab nrab carbon steel thiab nruab nrab carbon alloy steel nrog ib tug loj npaum li cas ntawm high-strength fasteners, spheroidizing annealing yog ua ua ntej txias taub hau, thiaj li yuav tau ib tug uniform thiab zoo spheroidized pearlite kom zoo dua raws li qhov tseeb ntau lawm.

2.high-strength bolt daim duab

Lub hom phiaj ntawm cov txheej txheem kev kos duab yog los hloov qhov loj ntawm cov ntaub ntawv raw, thiab qhov thib ob yog kom tau txais cov cuab yeej cuab tam ntawm cov fastener los ntawm deformation thiab ntxiv dag zog.Yog tias qhov kev faib tawm ntawm qhov txo qis ntawm txhua qhov dhau los tsis tsim nyog, nws tseem yuav ua rau cov kab nrib pleb tawg hauv cov hlua hlau xaim thaum lub sijhawm teeb duab.Tsis tas li ntawd, yog hais tias lub lubrication tsis zoo thaum lub sij hawm kev kos duab, nws kuj tuaj yeem ua rau cov kab nrib pleb tsis tu ncua hauv qhov txias rub hlau pas nrig.Lub tangent kev taw qhia ntawm cov hlau pas nrig thiab hlau daim duab tuag tib lub sij hawm thaum lub hlau pas nrig yog dov tawm ntawm lub pellet hlau tuag lub qhov ncauj tsis concentric, uas yuav ua rau lub hnav ntawm lub unilateral qhov qauv ntawm cov hlau drawing tuag rau aggravate. , thiab lub puab lub qhov yuav tawm ntawm puag ncig, uas ua rau tsis sib luag daim duab deformation nyob rau hauv lub circumferential kev taw qhia ntawm cov hlau, ua rau lub roundness yog tsis kam, thiab lub cross-sectional kev nyuaj siab ntawm cov hlau hlau tsis zoo li thaum lub caij txias. txheej txheem taub hau, uas cuam tshuam rau qhov txias taub hau hla tus nqi.
