Kev tiv thaiv rau kev hloov pauv ntawm cov saw hlau dov
Raws li ib qho khoom siv kis tau dav dav, qhov zoo ntawmcov saw hlauyog qhov tseem ceeb rau kev ua haujlwm ruaj khov ntawm cov khoom siv kho tshuab. Kev vuam deformation yog ib qho teeb meem zoo hauv cov txheej txheem tsim khoom ntawm cov saw hlau. Nws yuav tsis tsuas yog cuam tshuam rau qhov tseeb thiab kev ua haujlwm ntawm cov saw hlau, tab sis kuj tseem yuav ua rau cov khoom pov tseg thiab ua rau cov nqi tsim khoom nce ntxiv. Tsab xov xwm no yuav qhia txog cov kev ntsuas tiv thaiv rau kev vuam deformation ntawm cov saw hlau kom ntxaws, vam tias yuav muab qee cov ntaub ntawv pab tau rau kev tsim cov saw hlau.
1. Ua rau muaj kev hloov pauv ntawm kev vuam
Ua ntej tham txog cov kev ntsuas tiv thaiv, cia peb xub nkag siab txog qhov ua rau muaj kev hloov pauv ntawm cov saw hlau dov. Thaum lub sijhawm vuam, qhov cua sov kub hauv zos yuav ua rau cov khoom nthuav dav thiab ntsws tom qab txias. Qhov kev nthuav dav thiab kev sib cog lus tsis sib xws ntawm cov cua sov no yog qhov ua rau muaj kev hloov pauv ntawm cov vuam. Tsis tas li ntawd, cov yam xws li cov txheej txheem vuam, cov khoom siv, thiab kev tsim qauv kuj tseem yuav cuam tshuam rau kev hloov pauv ntawm cov vuam.
2. Kev xaiv khoom siv
Kev xaiv cov khoom siv kom zoo yog lub hauv paus rau kev tiv thaiv kev hloov pauv ntawm kev vuam. Piv txwv li, kev xaiv cov khoom siv uas muaj cov coefficients nthuav dav thermal me me thiab lub zog siab tuaj yeem txo qhov hloov pauv thaum vuam. Tib lub sijhawm, qhov huv ntawm cov khoom siv kuj tseem ceeb heev. Cov khoom siv uas muaj ntau yam tsis huv yuav ua rau muaj qhov tsis zoo xws li qhov hws thiab tawg thaum vuam, yog li ua rau muaj kev pheej hmoo ntawm kev hloov pauv.
3. Kev Tsim Qauv Zoo Tshaj Plaws
Thaum lub sijhawm tsim cov saw hlau, qee yam kev ntsuas tuaj yeem ua tau los tiv thaiv kev vuam deformation. Piv txwv li, sim siv cov qauv sib npaug, uas tuaj yeem sib npaug cov cua sov nkag thaum lub sijhawm vuam thiab txo qhov deformation. Tsis tas li ntawd, kev tsim qauv tsim nyog ntawm qhov loj me thiab qhov chaw ntawm qhov vuam kom tsis txhob muaj kev sib sau ua ke ntawm qhov vuam kuj tseem tuaj yeem txo qhov degree ntawm kev vuam deformation.
4. Kev tswj cov txheej txheem vuam
Qhov cuam tshuam ntawm cov txheej txheem vuam rau kev hloov pauv vuam yog qhov tseem ceeb heev. Kev xaiv cov yam ntxwv tsim nyog xws li txoj kev vuam, tam sim no vuam, voltage thiab qhov ceev vuam tuaj yeem tswj tau qhov nkag ntawm qhov kub vuam thiab yog li txo qhov deformation. Piv txwv li, kev siv cov txheej txheem vuam cua sov qis xws li pulsed argon arc vuam tuaj yeem txo qhov thermal nthuav dav thiab kev cog lus thaum lub sijhawm vuam.
5. Ua ntej deformation thiab rigid fixation
Ua ntej vuam, cov khoom ntawm cov saw hlau tuaj yeem raug deformed ua ntej los tsim cov deformation sib txawv rau qhov xav tau deformation thaum vuam, yog li them rau qhov deformation los ntawm kev vuam. Tsis tas li ntawd, kev siv cov txheej txheem kho kom ruaj khov, xws li kev siv clamps, tuaj yeem txwv qhov deformation thaum vuam. Txawm li cas los xij, nws yuav tsum tau sau tseg tias tom qab vuam tiav lawm, cov kev txwv yuav tsum tau tso tawm raws sijhawm kom tsis txhob muaj kev ntxhov siab ntau dhau.
6. Kev vuam sib law liag thiab kev taw qhia
Kev vuam uas tsim nyog thiab kev coj ua zoo tuaj yeem tswj tau qhov kev hloov pauv ntawm kev vuam. Piv txwv li, kev siv cov txheej txheem vuam sib npaug thiab vuam cov vuam hauv qhov chaw sib npaug ua ntej tuaj yeem sib npaug qhov kev faib cua sov thaum lub sijhawm vuam thiab txo qhov kev hloov pauv. Tib lub sijhawm, kev xaiv qhov kev coj vuam tsim nyog, xws li vuam los ntawm nruab nrab mus rau ob sab, kuj tuaj yeem pab tswj qhov kev hloov pauv ntawm kev vuam.
7. Kev kho cua sov tom qab vuam
Kev kho cua sov tom qab vuam tuaj yeem tshem tawm cov kev ntxhov siab seem ntawm vuam thiab txhim kho kev teeb tsa thiab kev ua haujlwm ntawm cov khoom. Piv txwv li, kev annealing tuaj yeem tso tawm cov kev ntxhov siab sab hauv cov khoom thiab txo qhov deformation.
8. Kev tshuaj xyuas thiab tswj xyuas zoo
Tsim kom muaj ib lub tshuab tshuaj xyuas zoo nruj heev los saib xyuas thiab tshuaj xyuas cov txheej txheem vuam ntawm cov saw hlau hauv lub sijhawm tiag tiag. Los ntawm kev kuaj pom qhov deformation thaum lub sijhawm vuam, tshawb pom thiab daws cov teeb meem raws sijhawm kom ntseeg tau tias cov khoom zoo.
Hauv ntej, kev tiv thaiv kev hloov pauv ntawm cov hlau dov vuam yuav tsum muaj ntau yam, suav nrog kev xaiv cov khoom siv, kev tsim qauv zoo, kev tswj cov txheej txheem vuam, kev kho ua ntej thiab kev ruaj khov, kev vuam ua ntu zus thiab kev taw qhia, kev kho cua sov tom qab vuam, thiab kev tshuaj xyuas zoo thiab kev tswj hwm.
