ERW Tube Ua Tshuab Ua Haujlwm Series - Ntu 3: Fine-Tuning Roll Stands rau Optimal Tube Zoo

Hauv kev teeb tsa yav dhau los, peb tau hais txog qhov kev teeb tsa thawj zaug thiab qhov sib dhos ua ke. Tam sim no, peb npaj txhij mus dhia mus rau hauv cov txheej txheem zoo-tuning: Kho tus neeg yob sawv ntsug kom ua tiav lub raj zoo meej profile thiab du, zoo ib yam weld. Cov kauj ruam no yog qhov tseem ceeb rau kev ua kom cov khoom kawg ua tau raws li koj cov qauv zoo.

Nkag siab txog qhov tseem ceeb ntawm Fine-Tuning

Tom qab qhov kev teeb tsa thawj zaug thiab qhov sib npaug ntawm qhov zawj, qhov zoo-tuning txhua qhov ntawm cov yob sib sau ua haujlwm yuav ua kom muaj tseeb thiab zoo ib yam ntawm cov raj. Txhua qhov ntawm qhov tseem ceeb yob sawv yuav raug hais kom xa cov kev ua tau zoo thiab raug.

Txoj Kev Kho Kom Zoo

I. Kab rov tav Roll Stand Kho

1. Vertical Positioning:Kho cov kab rov tav yob sawv ntsug kom tsa qhov nruab nrab ntawm cov ncej hauv qab mus rau txoj haujlwm xav tau.
2. Vertical Force:Siv cov kev hloov kho lub cev muaj zog kom txo qis cov ncej sab saud, teeb tsa qhov sib txawv ntawm cov yob sab saud thiab qis raws li daim duab zawj.
3. Axial Clearance:Kho cov axial clearance los xyuas kom meej tias cov groove centre ntawm lub sab sauv thiab qis rollers yog ncaj qha mus rau ib leeg los lav lub raj precision.

II. Vertical Roll Adjustments

Kho qhov nruab nrab ntawm qhov nruab nrab ntawm ob txoj hlua ntsug los ntawm kev tig cov ntsia hlau hlau kom phim cov yob txoj kev profile ntawm qhov tam sim no dhau. Yog hais tias muaj skew nrog lub dov centerline, nws kuj yuav tsum tau hloov kho rau nruab nrab ntawm txoj kab.

III. Qhia Roll Stand Kev Kho

1. Optimal Positioning:Kho cov ntawv qhia yob sawv ntsug rau txoj haujlwm tsim nyog, thiab kho qhov nruab nrab ntawm cov ntawv qhia rolls kom sib haum nrog cov dov centerline.
2. Axial Kho:Kho qhov axial txoj hauj lwm ntawm yob ncej.
3. Qhib lub kaum sab xis hloov:Kho txoj haujlwm ntawm phau ntawv qhia yob sawv ntsug ntawm lub rooj ua haujlwm kom hloov lub kaum sab xis qhib, uas yooj yim rau vuam.

IV. Squeeze Roll Adjustments

1. Roll Installation:Txhim kho cov nyem yob thiab cov ntaub ntawv yob sib thooj.
2. Center Distance Adjustment:Qhov nruab nrab ntawm qhov nruab nrab ntawm ob qhov nyem yob yuav tsum tau hloov kho kom haum rau qhov zawj ntawm qhov nyem yob.
3. Centering:Yog tias nws pom tias qhov chaw zawj tsis sib haum nrog lub dov centerline, kho rau qhov nruab nrab.

V. Weld Scarffing Device Kho

Kho cov cuab yeej tuav rau ntsug thiab kab rov tav txav kom cov ntug txiav yog ua raws li cov weld seam ntawm lub raj tsis muaj welded.

VI. Rough Straightening Adjustments

1. Kev kho kom txo qis:Kho tus nqi ntawm qhov txo kom haum rau lub raj tiav txoj kab uas hla.
2. Positioning Adjustment:Kho cov hauj lwm ntawm kab rov tav thiab ntsug chais kom qhov chaw ntawm lawv grooves yeej coincides nrog lub dov centerline.

Npaj rau Kev Xeem Khiav

Cov kev hloov kho saum toj no yuav tsum tau ua ua ntej qhov kev xeem khiav. Cov kev hloov kho meej yuav raug ua nyob rau hauv-situ, yog li cov kauj ruam saum toj no tuaj yeem suav tias yog qhov pib tsis zoo. Ua kom nws zoo pib nrog ib txoj kab zoo thiab du. Qhov ntawd txhais tau hais tias ua tib zoo saib thaum lub sijhawm npaj thiab kev teeb tsa yuav them cov nyiaj faib.
