Cuaj yam uas cuam tshuam rau kev kho kom sov co kho (二)
Thib tsib. Mob khaub thuas thiab kho kom zoo
Kev kho mob khaub thuas yuav txhawb nqa cov kab mob sib kis, cov dej kub qis dua, thiab cov deformation me dua quenching thiab txias, tiam sis qhov kev nyuaj siab thaum lub sijhawm no loj heev, thiab tawg yog yooj yim tshwm sim los ntawm qhov kev hloov ntawm kev ntxhov siab, theem kev hloov siab thiab thermal ntxhov siab.
Thib rau, npau taws thiab deformation
Thaum lub sijhawm kub ntxhov, qhov kev ntxhov siab tsis ua kom zoo, txo los yog zoo li qub, thiab kev deformation ntawm kev ua haujlwm tsis zoo, tab sis tib lub sij hawm, thaum deformation tshwm sim, nws tsis yooj yim kho. Yuav kom kho qhov kev deformation no, ib txoj kev xws li nias lossis tiv thaiv npawv feem ntau ua hauj lwm.
Xya, rov quenching thiab deformation
Feem ntau, cov hauj lwm tom qab ib quenching rov qab quenched tsis intermediate kev txiav, thiab deformation nce. Rov ua kev quenching deformation, tom qab rov quenching, nws cov deformation nce thiab nyhav kom kheej kheej kheej, tab sis cov duab tseem ruaj khov, tsis yooj yim rau deform, ces intermediate annealing yuav tsum tau ntxiv ua ntej rov quenching, tus xov tooj ntawm rov quenching yuav tsum yuav tsum tsawg tshaj li Equal rau 2 lub sij hawm (tsis suav thawj kev quenching).
Yim. Qhov kev nyuab siab thiab deformation
Thaum lub sij hawm cua sov txheej txheem, lub hlau yog hloov los ntawm ib qho elastomer mus rau ib tug plastomer ntawm txog 450 ° C, yog li nws yog ib qho yooj yim uas muaj pov thawj yas deformation. Nyob rau tib lub sijhawm, qhov kev ntxhov siab residual tseem yuav ploj vim yog rov ua kom zoo dua thaum nws siab dua saum toj no. Yog li, thaum muaj cua kub ceev, vim qhov txawv ntawm qhov nruab nrab ntawm sab hauv thiab sab nrauv ntawm haujlwm, lub sab nraud kub ncav 450 ° C thiab ua ib thaj tsam zoo. Thaum lub qhov kub thiab txias tsis tshua muaj, muaj kev ntxhov siab thiab qhov deformation tshwm sim. Tom qab txias, thaj av ntawd yog qhov deformation tshwm sim. Txij li thaum nws tsis yooj yim kom ua tau zoo thiab ua kom cua sov qeeb hauv cov txheej txheem ntau lawm, nws yog ib qho tseem ceeb uas yuav tsum ua kom muaj kev ntxhov siab ua ntej yuav quenching. Ntxiv nrog rau kev tshem tawm kev ntxhov siab los ntawm cua kub, nws tseem siv tau los siv kev vibration kom tshem tawm kev ntxhov siab rau loj qhov chaw.
Xyaum siv cov khoom siv ua kom muaj siab kub kho
