Cov khoom siv yooj yim xav tau ntawm cov menyuam cov kabmob feem ntau yog nyob ntawm kev ua haujlwm ntawm cov kabmob. Kev xaiv cov khoom siv rau kev sib tw cov kabmob muaj qhov cuam tshuam loj rau lawv qhov kev ua tau zoo thiab kev ua haujlwm. Feem ntau, cov ntaub ntawv tseem ceeb ntawm kev puas tsuaj ntawm cov kabmob dov yog qaug zog spalling nyob rau hauv qhov kev txiav txim ntawm kev hloov pauv kev ntxhov siab, thiab poob ntawm kev coj tus kheej raug vim kev sib txhuam hnav. Tsis tas li ntawd, muaj cov kab nrib pleb, khawb, xeb thiab lwm yam ua rau muaj kev puas tsuaj tsis zoo ntawmhla cov menyuam kev coj tus kheej.Yog li ntawd, cov khoom siv coj los yuav tsum ua tau raws li txhua qhov yuav tsum tau ua ntawm kev hla tus kheej cov menyuam. Tam sim no - tau paub cov ntsiab lus tseem ceeb ntawm cov khoom siv hla cov menyuam;
1, Kev tiv tauj siab qaug zog
Kev tiv tauj tsis muaj zog yog daim ntawv tseem ceeb ntawm kev ua tsis tiav. Thaum cov kabmob coj los ua haujlwm, cov khoom sib dhos txav ntawm qhov sib tw ntawm sab hauv thiab sab nraud ntawm lub nplhaibhla cov menyuam kev coj tus kheej, thiab nws qhov kev sib cuag yog dais lub sijhawm hloov pauv, uas tuaj yeem mus txog ntau pua txhiab lub sijhawm hauv ib feeb. Nyob rau hauv qhov rov ua dua ntawm kev hloov pauv ib ntus, kev sib cuag zoo li ua rau nkees nkees. Thaum cov kabmob dov pib tev tawm, qhov kev co thiab suab nrov ntawm cov kabmob yuav nce ntxiv, kev ua haujlwm kub yuav nce sai, thiab cov kabmob yuav raug puas tsuaj, uas hu ua kev sib cuag tsis muaj zog. Yog li ntawd, cov kabmob hlau yuav tsum muaj kev sib cuag siab zog.
2, Siab hnav tsis kam
Thaum cov kabmob coj los ua haujlwm ib txwm muaj, tsis yog tsuas yog dov kev sib txhuam tab sis kuj tseem swb kev sib txhuam. Lub luag haujlwm tseem ceeb ntawm kev sib txhuam tshwm sim los ntawm kev hloov zawv zawg yog qhov chaw sib cuag ntawm cov khoom sib dhos thiab kev tswj kev sib tw, qhov chaw sib cuag ntawm cov khoom sib dhos thiab cov thaiv kev sib cais, thiab nruab nrab ntawm kev sib cais thiab ferrule phau ntawv qhia kab. Lub hav zoov ntawm kev sib txhuam zawv zawg hauv cov kabmob uas tsis tuaj yeem ua rau hnav ntawm cov kabmob. Yog tias qhov hnav tsis kam ntawm cov kabmob hlau tsis zoo, cov kabmob sib tsoo yuav plam nws qhov tseeb ua ntej vim hnav, lossis kev co ntawm cov menyuam hla cov kabmob yuav nce ntxiv thiab kev pabcuam lub neej yuav txo qis vim qhov kev hloov pauv raug. Yog li ntawd, yuav tsum tau hnav siab ua haujlwm ntawm cov kabmob hlau yuav tsum tau ua.
3、 Siab elastic txwv
Thaum hla cov menyuam cov kabmob ua haujlwm, qhov sib tiv tauj ntawm qhov sib cuag ntawm cov kabmob yog loj heev nyob rau hauv qhov hnyav, tshwj xeeb tshaj yog nyob rau qhov hnyav. Txhawm rau tiv thaiv cov kabmob hlau los ntawm kev ua cov yas ntau dhau deformation nyob rau hauv kev sib cuag siab, uas yuav ua rau kev poob qis ntawm kev coj tus kheej lossis cov kab nrib pleb, cov kabmob hlau yuav tsum tau muaj qhov txwv qis dua.
4 、 Tsim kom muaj zog
Hardness yog ib qho tseem ceeb ntsuas ntawm kev coj tus kheej. Nws muaj feem cuam tshuam nrog cov khoom tiv tauj lub zog, hnav-ua haujlwm thiab txwv tsis pub muaj zog, thiab cuam tshuam ncaj qha rau kev pab cuam lub neej ntawm kev sib tw rau cov menyuam. Qhov nyuaj ntawm kev coj tus kheej feem ntau yog txiav txim siab los ntawm txoj kev thiab qhov loj ntawm kev nqa khoom, nqa qhov loj thiab phab ntsa tuab. Lub zog ntawm cov menyuam hla cov kabmob hlau yuav tsum tsim nyog, loj lossis loj dhau yuav cuam tshuam rau kev pabcuam lub neej ntawm Suav cov kabmob. Lub zog ntawm cov phab ntsa nyias nyias hla cov menyuam tau siab dua 60.
5. Ua rau muaj zog
Ntau tus menyuam hla cov menyuam yuav raug rau qee yam kev cuam tshuam hauv cov txheej txheem ntawm kev siv, yog li cov kabmob hlau yuav tsum tau muaj qee yam tawv kom ntseeg tau tias cov kabmob yuav tsis puas los ntawm kev cuam tshuam. Rau cov kabmob uas ua rau muaj kev cuam tshuam loj, xws li cov pob zeb sib tsoo thiab cov tsheb ciav hlau, cov khoom siv yuav tsum muaj qhov nruab nrab nruab nrab cuam tshuam qhov nyuaj thiab pob txha tawv. Qee qhov ntawm cov kabmob no siv cov txheej txheem kho cua sov cua sov, thiab qee qhov siv cov khoom siv hlau carburized, txhawm rau kom ntseeg tau tias cov kabmob no muaj qhov cuam tshuam zoo dua.
6, Zoo seem ruaj khov
Cov kabmob sib dhos yog qhov ua haujlwm tau zoo tshaj plaws, thiab nws qhov tseeb tau suav hauv micrometer. Hauv cov txheej txheem khaws cia thiab siv sijhawm ntev, kev hloov pauv ntawm cov txheej txheem sab hauv lossis kev nyuab siab yuav ua rau muaj kev hloov pauv ntawm cov kabmob loj, ua rau poob ntawm cov kabmob raug. Yog li ntawd, txhawm rau txhawm rau txhawm rau txheeb xyuas qhov tseeb ntawm cov menyuam hla cov kabmob, cov kabmob hlau yuav tsum muaj qhov zoo nyob ruaj khov.
Cov txheej txheem tsim tawm ntawmhla cov menyuam kev coj tus kheejyog ntau yam, thiab cov voj voog tsim khoom yog ntev. Qee cov khoom lag luam ib nrab lossis cov khoom tiav yuav tsum tau khaws cia ntev ua ntej sib dhos. Yog li ntawd, cov khoom nqa tau yooj yim rau xeb hauv cov txheej txheem tsim khoom lossis hauv kev khaws cia cov khoom tiav, tshwj xeeb tshaj yog nyob hauv huab cua ntawm Chaoxian. Yog li ntawd, nws yuav tsum tau hais tias cov kabmob hlau yuav tsum muaj qhov ua tau zoo los tiv thaiv kev ntxias. 8, Cov txheej txheem ua tau zoo
Hauv kev tsim cov txheej txheem ntawm cov kabmob, nws cov ntu yuav tsum dhau los ntawm ntau qhov txheej txheem ua haujlwm txias thiab kub. Qhov no xav tau tias cov kabmob hlau yuav tsum muaj cov txheej txheem ua haujlwm tau zoo, xws li kub, ua haujlwm kub ua haujlwm, txiav, sib tsoo thiab kho cua sov ua haujlwm, txhawm rau ua kom tau raws li qhov xav tau ntawm qhov hnyav ntau, ua haujlwm siab, tus nqi qis, thiab siab- kev tsim khoom zoo
Ib qho ntxiv, rau cov kabmob siv nyob rau hauv kev ua haujlwm tshwj xeeb, ntxiv rau cov kev xav tau saum toj no, yuav tsum tau ua haujlwm tshwj xeeb tshwj xeeb yuav tsum tau muab rau pem hauv ntej rau cov hlau, xws li kub tsis kam tiv taus, ua haujlwm nrawm, tiv thaiv corrosion, thiab ua haujlwm antimagnetic. Peb lub tuam txhab tuaj yeem tsim kho raws li qhov xav tau ntawm cov neeg siv khoom, cov khoom tshwj xeeb cov kabmob tuaj yeem ua tau raws li qhov xav tau ntawm cov khoom siv tsis yog tus qauv.
