1.Dab tsi cuam tshuam yuav muaj teeb meem nrog tus tswv ntim nws tus kheej?
Sickle Curve: Cov khoom siv coiled ua ib qho arc raws nws qhov ntev, uas yog ib qho nyuaj tshaj plaws los kho kom raug siv tus ntoo khaub lig- txiav kab.
Wave Shape: Qhov no suav nrog ntug wavy (wrinkling ntawm ob lub npoo), nruab nrab wavy (bulging nyob rau hauv nruab nrab ntawm daim ntawv), thiab tav wavy (ib ntus zoo nthwv dej). Cov no yog qhov tshwm sim ntawm qhov tsis sib xws hauv kev ntxhov siab.
Ntauwd Zoo: Tsis sib npaug winding tshwm sim nyob rau hauv ib tug pej thuam-zoo li lub ntsej muag kawg, cuam tshuam rau unwinding thiab noj stability.
Uneven Raw Material Properties: Tsis sib xws thickness, hardness, los yog zinc txheej thickness ntawm lub substrate ua ntej thiab tom qab galvanizing ua rau inconsistent kev ntxhov siab, ua rau nws nyuaj mus cuag zoo meej ncaj txawm tom qab straightening.
2.Dab tsi yuav cuam tshuam rau cov cuab yeej thiab cov txheej txheem siv nyob rau hauv tus ntoo khaub lig- txiav kab?
Muaj peev xwm tsis txaus lossis qhov chaw tsis raug ntawm lub tshuab straightening:
Tsis txaus tus naj npawb ntawm straightening rollers: ntau rollers, qhov zoo dua cov nyhuv straightening. Ib qho yooj yim hla- cov kab txiav tuaj yeem tsuas muaj 7-9 rollers, thaum cov kab siab yuav muaj 11-17 lossis ntau dua.
Kev teeb tsa cov menyuam tsis raug cai: Ntau dhau, tsis txaus, lossis tsis sib xws yuav tsis ua rau muaj kev ntxhov siab sab hauv.
Weared straightening rollers: Hnav cov chais tsis tuaj yeem siv zog rau cov ntawv hlau.
Shearing seem zoo: Cov hniav tsis raug tshem tawm lossis cov hniav dulled tuaj yeem ua rau burrs, torque, thiab txawm tias qhov chaw deformation ntawm cov ntawv hlau thaum shearing.
Kev tswj tsis ruaj tsis khov: Kev sib hloov ntawm kev sib hloov thaum lub sij hawm uncoiling, straightening, thiab winding yuav ua rau cov ntawv hlau yuav elongated los yog compressed, tsim tshiab waviness.
3.Yuav ua li cas kom ua tiav thiab txiav txim siab yog tias flatness ua tau raws li tus qauv?
Cov qauv siv
Feem ntau, lub teb chaws lossis cov qauv kev lag luam raug ua raws. Piv txwv li, Tuam Tshoj tus GB/T 708 "Dimensions, Shape, Weight and Permissible Deviations of Cold-Rolled Steel Sheets and Strips" qhia meej meej cov kev cai flatness rau cov ntawv hlau.
Lub flatness kam rau ua yuav tsum tau sib txawv nyob ntawm seb lub thickness thiab dav ntawm daim ntawv. Cov neeg siv kuj tuaj yeem tsim cov qauv kev lag luam lossis cov kev cai tshwj xeeb uas tshaj li cov qauv hauv tebchaws.
Kev tshuaj ntsuam xyuas
Platform Method: Muab cov ntawv tso ncaj nraim rau ntawm qhov chaw soj ntsuam thiab ntsuas qhov sib txawv siab tshaj plaws ntawm daim ntawv thiab lub platform siv lub ntsuas ntsuas ntsuas.
Txoj Kev Ncaj Ncees: Muab tus kav ncaj ncaj rau ntawm daim ntawv saum npoo thiab ntsuas qhov sib txawv siab tshaj plaws ntawm tus pas ntsuas thiab daim ntawv saum npoo.
4.Peb tuaj yeem tswj nws ntawm qhov chaw li cas?
Thaum lub sij hawm kev yuav khoom, qhia meej meej cov kev cai rau sab nraud tolerances ntawm tus tswv yob, xws li camber thiab waviness.
Ua ib qho kev tshuaj xyuas ua ntej ntawm tus tswv yob ua ntej nws mus rau hauv kev tsim khoom.
5.Peb yuav tsum xyuam xim rau dab tsi los xyuas kom meej tias qhov flatness ua tau raws li tus qauv tom qab hla- txiav?
Cov cuab yeej tu (Cross-txiav kab):
Ib tug ntoo khaub lig- txiav kab nruab nrog lub siab -rigidity, ntau- yob straightener tau xaiv.
Kev saib xyuas tsis tu ncua ntawm cov cuab yeej, tshwj xeeb tshaj yog hnav ntawm cov chais ncaj thiab shearing hniav, yog ua.
Kev Tswj Xyuas Txheej Txheem (Technology thiab Kev Ua Haujlwm):
Ncaj tsis ncaj (xws li qhov txo qis ntawm cov chais ncaj) yog hloov kho raws li qhov tseeb ntawm txhua yob (thickness, khoom, daim ntawv qub). Qhov no qhia txog tus neeg ua haujlwm qhov kev txawj ntse.
Optimize ntau lawm kab nro.
Xyuas kom tseeb tias qhov sib txawv shearing yog teem kom raug.
Tshaj tawm - kev ua haujlwm:
Sheared nplooj ntawv yuav tsum tau stacked tiaj tus nrog txaus txhawb nqa nyob rau hauv qab; pawg qhov siab yuav tsum tsis txhob siab dhau.
Siv cov cuab yeej tsim nyog rau kev tuav thiab nqa.
