Part.1 muaj kuab tsim qauv
Cov pwm yog tsim nyog tsim raws li qhov yuav tsum tau siv, thiab nws cov qauv qee zaum tsis tuaj yeem ua kom tsim nyog kiag li thiab tusyees conmmetrical. Qhov no yuav tsum muaj tus tsim qauv coj qee cov kev ntsuas siv tau thaum tsim cov pwm, thiab sim ua kom tau kev ua tau zoo ntawm cov qauv ntawm cov qauv ntawm cov duab geometric.
(1) Sim kom tsis txhob ntse fab sib txawv nrog qhov sib txawv zoo hauv cov tuab
Yuav tsum muaj kev hloov pauv ib qho ntawm kev sib tshuam ntawm tuab thiab nyias seem ntawm cov pwm. Qhov no tuaj yeem txo cov qhov kub ntawm cov pwm, txo cov kev ntxhov siab ntawm cov ntaub so ntswg, thiab qhov kev ntxhov siab ntawm cov nqaij mos. Daim duab 1 qhia tau hais tias cov pwm ua rau CANTS CANTS FORTTER thiab TRAVIT CONE.
(2) tsim nyog rau cov txheej txheem ua cov txheej txheem
Rau qee cov pwm uas tsis tuaj yeem lav tau cov khaub ncaws tsis sib xws thiab cov khoom sib dhos los ntawm qhov tsis muaj kev cuam tshuam yam tsis cuam tshuam dab tsi.
Daim duab 2A qhia txog kev tuag nrog kab noj hniav nqaim, uas yuav deformed raws li qhia los ntawm cov kab dotted tom qab quenching. Yog tias ob txoj kev yuav muaj nyob hauv daim duab (raws li muaj nyob hauv daim duab 2B), qhov kub kub sib txawv yog txo qis, thiab kev tawm tsam cua sov tau txhim kho.
(3) Siv cov qauv kaw thiab ua kom zoo li ntau tau
Thaum cov duab ntawm cov pwm yog qhib lossis asymmetrical, kev ntxhov siab faib tom qab quenching tsis ncaj thiab nws yog ib qho yooj yim rau deform. Yog li no, rau cov khoom siv dav dav tiv thaiv cov pwm, yuav tsum tau ua ua ntej quenching, thiab tom qab ntawd txiav tawm tom qab quenching. Cov kev ua haujlwm trough tau qhia hauv daim duab 3 yog Ameslikas decormed ntawm r tom qab r reinforinging, thiab hatchated ntu nyob rau hauv daim duab 3), muaj peev xwm tiv thaiv quenching deformation.
(4) Txais yuav cov qauv sib xyaw ua ke, uas yog, ua kom muaj kev sib txuas ua ke, cais cov khoom sib cais thiab qis dua pwm thiab cais cov tuag thiab xuas nrig
Rau cov tuag loj nrog cov duab nyuaj thiab qhov loj me> 400 hli thiab qhov ntev tshaj plaws los txais cov khoom sib xyaw ua ke, thiab hloov cov pwm sab hauv ntawm cov npoo sab nraud , uas tsis yog yooj yim rau cua sov thiab ua kom txias.
Thaum tsim qauv kev tsim qauv, nws yuav tsum feem ntau yog decomposed raws li cov ntsiab cai hauv qab no yam tsis cuam tshuam rau qhov haum haum:
- Kho cov tuab tuab kom cov ntoo khaub lig-ntu ntawm cov pwm nrog cov ntoo khaub lig sib txawv heev yog cov khaub ncaws tshwj xeeb tom qab kev txiav txim siab tom qab kev txiav txim.
- Decompose nyob rau hauv qhov chaw uas kev ntxhov siab yog qhov yooj yim los tsim, tawg nws txoj kev ntxhov siab, thiab tiv thaiv kev tawg.
- Koom tes nrog cov txheej txheem qhov kom ua rau cov qauv sib dhos.
- Nws yooj yim rau cov khaub thuas thiab kub ua thiab yooj yim sib dhos.
- Qhov tseem ceeb tshaj plaws yog ua kom peb muaj peev xwm.
Raws li muaj nyob hauv Daim Duab 4, nws yog ib qho kev tuag loj. Yog tias tus qauv txheej txheem tseem ceeb tau saws, tsis yog kev kho cua sov yuav nyuaj rau tom qab kev txiav txim siab ntawm txoj kev txiav, uas yuav nyuaj rau kev kho kom ua tiav. , yog li ntawd, tus qauv sib xyaw ua ke tuaj yeem raug saws. Raws li cov kab dotted hauv daim duab 4, nws tau muab faib ua plaub ntu, thiab tom qab kev kho cua sov, lawv tau sib sau ua ke, thiab tom qab ntawd av. Qhov no tsis yog yooj yim kho cua sov, tab sis kuj tseem ua cov teeb meem ntawm deformation.
Part.2 Cov Khoom Siv Muaj Kev Xaiv
Kev kho kom sov thiab tawg yog ze ze rau cov hlau siv thiab nws cov khoom zoo, yog li nws yuav tsum ua raws li cov kev xav tau ntawm pwm. Cov kev xaiv tsim nyog ntawm cov hlau yuav tsum tau coj mus rau hauv tus account qhov tseeb, cov qauv thiab qhov loj ntawm cov pwm, nrog rau cov xwm txheej, kom muaj nuj nqis thiab kev ua cov txheej txheem ntawm cov khoom tiav. Yog tias cov pwm dav dav tsis muaj deformation thiab precision yam yuav tsum tau, carbon Tool steel tuaj yeem siv rau hauv cov nqe lus ntawm kev txo tus nqi; Txhawm rau yooj yim deformed thiab tawg qhov chaw, alloy tuam steel nrog lub zog siab dua thiab qeeb qeeb twv tau quenching thiab cua txias ceev tuaj yeem siv; Piv txwv li, kev tuag hluav taws xob tuag ntawm T10a Hlau, deformation loj thiab yooj yim mus tawg tom qab dej txias, thiab alkali da dej quenchity tsis yooj yim rau tawv. Tam sim no siv 9MN2V Hlau lossis Crwmn Hlau lossis Quenching Hardness thiab deformation tuaj yeem ua tau raws li cov cai.
Nws tuaj yeem pom tau tias thaum deformation ntawm pwm ua los ntawm cov roj av ua kom tau raws li cov kev xav tau, nws tseem ua tau zoo siv AlloyOy Hlau lossis Crwmn Hlau. Txawm hais tias cov khoom siv tau me ntsis siab dua, qhov teeb meem ntawm deformation thiab kev tawg yog daws.
Thaum xaiv cov ntaub ntawv kom raug, nws tseem tsim nyog los txhawb cov tshuaj ntsuam xyuas thiab kev tswj hwm cov ntaub ntawv raw kom tiv thaiv pwm thaum cov khoom siv hluav taws xob tsis xws luag.
