Cov Zoo thiab Cov Tsis Zoo ntawm Kev Kho Mob Kub Rau Cov Menyuam
Kev kho cua sov yog ib kauj ruam tseem ceeb hauv cov txheej txheem tsim cov saw hlau. Txawm hais tias cov txheej txheem no tuaj yeem txhim kho tau zoo heevcov saw hlau
kev ua tau zoo, nws kuj muaj qee qhov tsis zoo tseem ceeb.
1. Cov Ntsiab Cai ntawm Kev Kho Mob Kub Rau Cov Menyuam
Kev kho cua sov ntawm cov saw hlau muaj xws li cua sov thiab txias tag nrho cov saw hlau kom txhim kho nws cov qauv sab hauv thiab yog li txhim kho nws cov khoom siv kho tshuab. Cov txheej txheem kho cua sov feem ntau suav nrog quenching, tempering, carburizing, thiab nitriding. Piv txwv li, quenching ua rau cov saw hlau txias sai sai los tsim cov qauv tawv ntawm qhov chaw thiab sab hauv, yog li ua rau muaj kev tawv thiab lub zog. Tempering, ntawm qhov tod tes, txo cov kev ntxhov siab sab hauv uas tsim thaum lub sijhawm quenching thiab ua rau cov saw hlau tawv dua.
2. Cov txiaj ntsig ntawm Kev Kho Mob Kub Rau Cov Menyuam
(1) Txhim Kho Lub Zog thiab Kev Nyuaj Siab Zoo
Kev kho cua sov tuaj yeem txhim kho lub zog thiab qhov tawv ntawm cov saw hlau. Los ntawm cov txheej txheem xws li quenching thiab tempering, cov qauv sab hauv ntawm cov saw hlau tau zoo tshaj plaws, ua rau cov qauv noob zoo dua, ua rau nws lub zog tensile thiab qhov tawv ntawm qhov chaw nce ntxiv. Qhov no tseem ceeb heev rau cov saw hlau uas yuav tsum tiv taus cov khoom hnyav thiab kev cuam tshuam ntau zaus, ua rau lawv lub neej ua haujlwm ntev dua.
(2) Kev Tiv Thaiv Kev Hnav Zoo Dua
Qhov kev tiv thaiv kev hnav ntawm cov saw hlau tom qab kev kho cua sov tau zoo dua qub. Piv txwv li, cov txheej txheem carbonitriding tsim cov txheej carbonitriding uas tiv thaiv kev hnav ntawm qhov chaw ntawm cov saw hlau, ua rau txo qhov hnav thaum lub sijhawm ua haujlwm. Qhov no tsis yog tsuas yog ua rau lub neej kev pabcuam ntev dua xwb tab sis kuj txo cov nqi kho uas tshwm sim los ntawm kev hnav.
(3) Lub Neej Qaug Zog Zoo Dua
Kev kho cua sov tag nrho zoo txo qhov kev ntxhov siab seem hauv cov saw hlau, yog li ua rau nws lub neej qaug zog ntev dua. Hauv kev siv tiag tiag, cov saw hlau uas kho cua sov tuaj yeem ua haujlwm ruaj khov thaum muaj kev thauj khoom ntau thiab pib thiab nres ntau zaus, txo qhov kev pheej hmoo ntawm kev tawg qaug zog.
(4) Kev Ua Tau Zoo Dua Tag Nrho
Kev kho cua sov tag nrho tsis yog tsuas yog ua kom lub zog thiab kev tiv thaiv kev hnav ntawm cov saw hlau xwb tab sis kuj tseem txhim kho nws qhov kev ua tau zoo tag nrho. Piv txwv li, cov saw hlau kho cua sov tuaj yeem ua tau zoo heev txawm tias nyob rau hauv qhov chaw nyuaj xws li kub thiab noo noo siab. Qhov no muaj qhov tseem ceeb rau cov saw hlau siv rau hauv cov xwm txheej ua haujlwm nyuaj.
3. Qhov tsis zoo ntawm Kev Kho Mob Kub Rau Cov Menyuam
(I) Kev Pheej Hmoo ntawm Kev Hloov Pauv Thaum Lub Sijhawm Kho Mob Kub
Thaum lub sijhawm kho cua sov, cov saw hlau yuav hloov pauv vim yog qhov kub thiab txias tsis sib xws. Qhov kev hloov pauv no tuaj yeem cuam tshuam rau qhov tseeb ntawm qhov ntev thiab qhov sib dhos, ua rau muaj teeb meem xws li cov saw hlau lo lossis cov hniav dhia thaum lub sijhawm ua haujlwm. Yog li ntawd, qhov kub thiab txias yuav tsum tau tswj hwm nruj me ntsis thaum lub sijhawm kho cua sov kom txo qhov ua tau ntawm kev hloov pauv.
(II) Cov Txheej Txheem Nyuaj thiab Tus Nqi Siab
Cov txheej txheem kho cua sov rau cov saw hlau yog qhov nyuaj, xav tau kev tswj hwm qhov tseeb ntawm cov yam ntxwv xws li qhov kub thiab txias, lub sijhawm tuav, thiab cov khoom siv txias. Qhov no tsis yog tsuas yog ua rau muaj kev xav tau ntau rau cov khoom siv thiab cov txheej txheem xwb tab sis kuj ua rau cov nqi tsim khoom nce ntxiv. Ntxiv mus, yuav tsum tau kuaj xyuas qhov zoo nruj thaum lub sijhawm kho cua sov kom ntseeg tau tias cov txiaj ntsig kho cua sov ruaj khov thiab ntseeg tau.
(III) Tej Yam Yuav Cuam Tshuam Rau Qhov Zoo Ntawm Qhov Chaw
Thaum lub sijhawm kho cua sov, oxidation thiab decarburization yuav tshwm sim rau ntawm qhov chaw ntawm cov saw hlau, cuam tshuam rau nws qhov zoo ntawm qhov chaw. Cov qhov tsis zoo ntawm qhov chaw no tsis yog tsuas yog cuam tshuam rau qhov tsos ntawm cov saw hlau xwb tab sis kuj txo nws qhov kev hnav thiab kev tiv thaiv corrosion. Yog li ntawd, kev kho qhov chaw kom zoo, xws li sandblasting thiab pleev xim, yog qhov yuav tsum tau ua tom qab kev kho cua sov kom txhim kho qhov zoo ntawm qhov chaw.
4. Xaus Lus
Kev kho cua sov tag nrho lub cev ntawm cov saw hlau muaj ntau yam zoo, xws li ua kom muaj zog dua, tawv dua, tiv taus kev hnav, thiab lub neej qaug zog, ua rau kev ua haujlwm thiab kev pabcuam ntawm cov saw hlau zoo dua. Txawm li cas los xij, cov txheej txheem no kuj muaj qhov tsis zoo, suav nrog kev pheej hmoo ntawm kev kho cua sov deformation, ib qho txheej txheem nyuaj thiab kim dua, thiab qhov ua rau qhov zoo ntawm qhov chaw puas tsuaj.
