Xov dov tuagyog cov cuab yeej tseem ceeb hauv kev tsim khoom lag luam rau kev ua cov xov ntawm workpieces.Cov tuag no yog tsim los deform cov khoom siv ua haujlwm los tsim cov xov xov xav tau.Cov khoom siv hauv xov dov tuag plays lub luag haujlwm tseem ceeb hauv kev txiav txim siab qhov zoo thiab kav ntev ntawm cov xov tsim.Yog li ntawd, xaiv qhov zoo tshaj plaws xov dov tuag khoom yog qhov tseem ceeb heev kom tau txais cov khoom zoo threaded.
Qhov zoo tshaj plawscov ntaub ntawv rau xov dov tuagyuav tsum muaj ntau yam khoom tseem ceeb los xyuas kom meej qhov ua tau zoo thiab ua haujlwm ntev.Ib qho tseem ceeb tshaj plaws los xav txog yog qhov hardness ntawm cov khoom.Xov rolling tuag yog raug rau kev kub siab thiab kev sib txhuam thaum lub sij hawm dov txheej txheem, yog li cov khoom yuav tsum muaj peev xwm tiv taus cov rog no yam tsis muaj deforming sai lossis hnav tawm.Feem ntau, cov ntaub ntawv siab hardness xws li cov cuab yeej steel yog nyiam rau kev tsim cov xov dov tuag.
Cov cuab yeej steel, suav nrog D2, A2, thiab M2, feem ntau siv hauvmanufacturing xov dov tuags vim lawv zoo heev hardness thiab hnav tsis kam.Cov hlau no tuav lawv cov duab thiab ntse txawm tias nyob rau hauv qhov kev ntxhov siab thiab cua sov tsim thaum dov.Tsis tas li ntawd, lawv tuaj yeem raug kho kom sov kom ntxiv dag zog thiab toughness, ua rau lawv zoo tagnrho rau kev siv mus ntev hauv xov dov daim ntaub ntawv.
Ntxiv nrog rau hardness, cov ntaub ntawv siv hauvxov dov tuagNws tseem yuav tsum muaj qhov zoo toughness thiab lub zog.Qhov no yog ib qho tseem ceeb los tiv thaiv cov pwm los ntawm chipping, cracking los yog tawg thaum lub sij hawm dov txheej txheem.Cov cuab yeej hlau tau paub txog lawv cov tawv tawv siab, uas tso cai rau lawv los tiv thaiv kev poob siab thiab kev sib tw cyclic thaum lub sijhawm ua haujlwm xov.
Lwm qhov kev xav tseem ceeb hauv kev xaiv cov khoom siv zoo tshaj plaws rau xov dov tuag yog hnav tsis kam.Nyob rau tib lub sijhawm, kev sib cuag tsis tu ncua ntawm cov pwm thiab cov khoom ua haujlwm ua rau hnav, uas tuaj yeem cuam tshuam qhov zoo ntawm cov xov uas tsim.Yog li ntawd, cov khoom siv yuav tsum muaj kev hnav zoo heev los tswj nws txoj kev txiav thiab nto tiav rau lub sijhawm ntev.Cov cuab yeej steel paub txog nws qhov hnav tsis kam, ua rau nws yog thawj qhov kev xaiv rau kev tsim cov xov dov tuag.
Tsis tas li ntawd, lub peev xwm los tshuab thiab cua sov kho cov khoom yog qhov tseem ceeb rautsim xov dov tuagnrog meej qhov ntev thiab zoo hardness.Cov cuab yeej steel muaj kev ua haujlwm zoo thiab tuaj yeem tsim cov pwm sib txawv thiab cov xov geometry.Tsis tas li ntawd, lawv tuaj yeem raug kho kom sov kom ua tiav qhov yuav tsum tau ua kom tawv tawv, kom ntseeg tau tias cov xov dov tuag tuaj yeem tsim cov khoom ua haujlwm zoo yam tsis muaj kev hnav khaub ncaws ntau dhau.
