Hauv kev tsim cov ntawv ci ob npaug, lub dov ntawm aluminium ntawv ci muab faib ua peb txheej txheem: ntxhib dov, nruab nrab dov thiab ua tiav dov. Los ntawm kev siv thev naus laus zis, nws tuaj yeem sib cais raws li qhov tuab ntawm qhov tawm ntawm dov. Txoj kev faib tawm dav dav yog tias qhov tawm thickness ntau dua los yog sib npaug rau {{0}}}05mm yog qhov ntxhib dov, qhov tawm thickness ntawm 0.013 thiab 0.05 yog nruab nrab dov, thiab ib qho khoom tiav thiab ob chav dov tiav cov khoom nrog tawm thickness tsawg dua 0.013mm yog tiav dov. Cov yam ntxwv dov ntawm ntxhib dov thiab txhuas phaj thiab sawb zoo sib xws. Lub thickness tswj tsuas yog nyob ntawm lub dov quab yuam thiab tom qab nro. Lub thickness ntawm ntxhib dov yog tsawg heev. Nws cov yam ntxwv dov yog txawv kiag li los ntawm dov ntawm txhuas phaj thiab sawb. Nws muaj cov yam ntxwv ntawm aluminium foil dov. Qhov tshwj xeeb ntawm nws feem ntau suav nrog cov hauv qab no:
(1) Aluminium phaj thiab sawb dov. Ua kom cov txhuas sawb thinner feem ntau yog nyob ntawm lub zog dov, yog li txoj kev tswj tsis siv neeg ntawm cov phaj tuab yog ua raws li qhov sib txawv ntawm qhov sib txawv raws li txoj kev tswj lub ntsiab ntawm AGC. Txawm hais tias lub zog dov hloov, qhov tuab tuaj yeem tau txais los ntawm kev kho qhov sib txawv ntawm qhov yob txhua lub sijhawm kom cov yob sib txawv ntawm ib qho nqi. Cov ntaub ntawv sib xws thiab cov khoom siv strip. Thaum cov ntawv txhuas yog dov mus rau nruab nrab-tiav dov, vim tias lub thickness ntawm cov ntawv txhuas yog nyias nyias, lub zog dov yog nce thaum dov, ua rau nws yooj yim rau cov menyuam los tsim elastic deformation dua li cov khoom siv los tsim cov yas deformation. Lub elastic flattening ntawm cov menyuam tsis tuaj yeem tsis quav ntsej, qhov elastic rolling thiab flattening ntawm cov menyuam txiav txim siab tias nyob rau hauv aluminium ntawv ci dov, lub dov quab yuam tsis plays tib lub luag hauj lwm li dov daim hlau. Aluminium foil dov yog feem ntau yob qhov sib txawv-dawb dov nyob rau hauv lub siab tsis tu ncua, thiab lub thickness ntawm aluminium ntawv ci yog kho. Feem ntau yog nyob ntawm qhov kho qhov nro thiab dov ceev.
(2) Overlapping yob. Rau cov ntawv txhuas nyias nyias nrog lub thickness tsawg dua 0.012 hli (qhov tuab yog cuam tshuam nrog txoj kab uas hla ntawm cov yob ua haujlwm), vim yog elasticity ntawm yob, nws nyuaj heev rau yob. nws nrog ib daim ntawv. Yog li ntawd, ob txoj kev dov yog siv, uas yog, txoj kev ntxiv cov roj lubricating ntawm ob lub txhuas ntawv ci thiab ces dov lawv ua ke (tseem hu ua pawg dov). Laminated dov tuaj yeem tsis tsuas yog yob tawm cov ntawv txhuas nyias nyias uas tsis tuaj yeem tsim los ntawm ib qho yob, tab sis kuj txo tus naj npawb ntawm cov sawb so thiab txhim kho kev ua haujlwm. Cov txheej txheem no tuaj yeem siv los tsim cov ntawv txhuas ib leeg ntawm 0.006mm txog 0.03mm.
(3) Cov nyhuv nrawm. Thaum lub sij hawm cov txheej txheem aluminium ntawv yob, qhov tshwm sim uas lub thickness ntawm cov ntawv ci yuav thinner nrog rau qhov nce ntawm dov degree yog hu ua cov nyhuv ceev. Qhov kev piav qhia ntawm cov nyhuv nrawm nrawm tseem xav tau kev tshawb fawb tob. Cov laj thawj rau cov nyhuv nrawm feem ntau ntseeg tias muaj peb yam hauv qab no:
1) Kev sib txhuam lub xeev ntawm kev ua haujlwm yob thiab cov khoom siv dov hloov. Raws li lub dov ceev nce, tus nqi ntawm cov roj lubricating tau nce, yog li ua rau lub xeev lubrication ntawm cov yob thiab cov khoom dov hloov. Kev sib txhuam coefficient txo qis, cov roj zaj duab xis yuav thicker, thiab lub thickness ntawm aluminium ntawv ci yuav thinner.
2) Kev hloov pauv hauv lub tshuab dov nws tus kheej. Nyob rau hauv ib lub rolling zeb siv cylindrical bearings, raws li lub dov ceev nce, lub caj dab yob yuav ntab nyob rau hauv cov kabmob, kom ob tug interacting loaded yob yuav txav los ze zog rau ib leeg.
3) Cov txheej txheem softening thaum cov khoom yog deformed los ntawm dov. Lub dov ceev ntawm high-speed aluminium foil dov zeb yog siab heev. Raws li qhov dov ceev nce, qhov kub ntawm qhov dov deformation cheeb tsam nce. Raws li kev suav, cov hlau kub hauv thaj tsam deformation tuaj yeem nce mus rau 200 degree, uas yog sib npaug rau qhov nruab nrab rov qab annealing, yog li ua rau txheej txheem softening tshwm sim ntawm cov ntaub ntawv dov.
