1.Yuav ua li cas cov khoom raug thiab cov xwm txheej cuam tshuam qhov sib txawv ntawm qhov sib txawv?
Kev vibration thiab hnav ntawm lub cutter ncej system: Qhov no yog thawj yam uas ua rau dav deviations. Piv txwv li, nyob rau hauv ib rooj plaub, cutter ncej vibration ua rau cov khoom dav kam rau siab mus txog ± 0.3mm, deb tshaj tus qauv ± 0.1mm. Qhov ua rau feem ntau yog nce bearing clearance, ntau dhau radial runout ntawm lub cutter ncej, los yog cov cuab yeej imbalance.
Tswj cov qauv: Cutter ncej radial runout yuav tsum tau tswj<0.01mm; bearing clearance should be controlled to 0.02-0.03mm using pre-tightening technology; residual imbalance in online dynamic balancing should be less than 0.5g·mm/kg.
Cov cuab yeej tsis raug thiab qhov chaw tshem tawm: Cov cuab yeej hnav lossis tsis tsim nyog rau kev tshem tawm sab saud thiab qis thiab sib tshooj yuav tsis tsuas yog tsim cov burrs tab sis kuj cuam tshuam rau qhov dav dav dav.
Kev tswj cov qauv: Cov cuab yeej sab saud thiab qis dua yuav tsum feem ntau yog 8% -12% ntawm cov khoom tuab; Cov cuab yeej sib tshooj yuav tsum tau hloov kho raws li qhov tuab (piv txwv li, 0.03-0.05mm rau nyias daim hlau hauv qab 0.3mm). Cov cuab yeej ntug roughness yuav tsum tsawg dua Ra 0.4μm.
2.Yuav ua li cas cov txheej txheem tsis cuam tshuam qhov sib txawv ntawm qhov sib txawv?
Kev tswj tsis ruaj tsis khov: Kev sib hloov ntawm qhov nro ntau dhau tuaj yeem ua rau cov hlua hlau ncab thiab deform los yog deviate thaum slitting, ncaj qha cuam tshuam rau qhov dav sib xws tom qab slitting. Precision txiav yuav tsum tsim kom muaj kev sib txuas ntawm kev sib txuas ntawm qhov nro thiab ceev (piv txwv li, V²·T=tus nqi tas li).
Kev tswj tus qauv: Lub kaw - lub voj nro tswj qhov system yuav tsum tau siv los tswj qhov kev hloov pauv tsis pub dhau ± 5%.
Kev tsis sib haum xeeb ntawm kev txiav ceev thiab cov khoom siv: Kev ceev ntau dhau yuav ua rau muaj kev vibration hnyav dua, thaum ceev ceev yuav cuam tshuam rau kev tsim khoom. Cov ntaub ntawv sib txawv thiab thicknesses txias -rolled coils muaj lawv cov kev pom zoo linear speed ranges.
Tswj tus qauv: Piv txwv li, rau 0.3-1.2mm txias-rolled low-carbon steel, qhov pom zoo linear ceev yog 60-80 m / min. Rau txhua txhua 0.1 hli hloov nyob rau hauv thickness, qhov ceev yuav tsum tau kho los ntawm ± 5%.
3.Yuav ua li cas cov khoom muaj feem cuam tshuam qhov sib txawv ntawm qhov sib txawv?
Cov ntawv xa tuaj thiab cov tuab tsis sib xws: Yog tias daim ntawv tuaj ntawm nws tus kheej muaj camber, waviness, los yog tsis sib xws transverse thickness (wedge shape), qhov kev ntxhov siab tso tawm tom qab slitting yuav ua rau ntxiv deformation thiab dav fluctuations nyob rau hauv lub sawb.
Residual stress: Residual stress in the steel coil yog redistributed thaum lub sij hawm slitting, uas tej zaum kuj yuav ua rau me ntsis hloov nyob rau hauv lub strip loj.
4.Kuv yuav txiav txim li cas yog tias qhov sib txawv yog "tawm ntawm kev tswj hwm"?
Ua ntej tshawb xyuas qhov laj thawj, nws yog ib qho tseem ceeb kom paub meej tias qhov kev sib txawv tiag tiag tshaj tus qauv. Raws li cov ntaub ntawv muaj, muaj cov kev cai tshwj xeeb hais txog qhov kev tso cai dav dav ntawm qhov sib txawv ntawm qhov txias txias -rolled steel sheets (strips).
Piv txwv li, rau steel strips thickness ntawm 0.4 thiab 1.0 hli:
Thaum qhov dav tsawg dua lossis sib npaug li 125 mm, qhov kev tso cai sib txawv yog +0.3 hli.
Thaum qhov dav yog nyob nruab nrab ntawm 125 thiab 250 hli, qhov kev tso cai sib txawv yog +0.6 hli.
5.Dab tsi yog qee cov lus qhia daws teeb meem ceev?
Kev tshuaj xyuas cov cuab yeej: Nrog lub tshuab nres, xyuas cov radial runout ntawm lub cutter ncej, tshem tawm cov cuab yeej, thiab hnav.
Kev soj ntsuam cov txheej txheem: Tshawb xyuas cov ntaub ntawv tsim khoom kom ntseeg tau tias qhov nro thiab nrawm nyob rau hauv qhov kev pom zoo thiab ua kom pom qhov hloov pauv tsawg.
Incoming Material Inspection: Ua random checks ntawm lub thickness uniformity thiab cov duab ntawm cov ntaub ntawv raw.
