TEJ YAM YUAV TSUM MUAJ NYOB RAU HAUV TXOJ KEV UA HAUJ LWM NTAWM LUB TSHUAB ROLL FORMING THIAB COV KEV DAWS TEJ YAM

1. Strip nthwv dej:
Cov nthwv dej ntawm daim ntawv tshwm sim vim muaj kev sib zog thiab kev ntxhov siab ntawm cov ntawv thaum cov ntawv raug khoov los ntawm lub tshuab dov, tab sis kev ntxhov siab ntawm daim ntawv raws li qhov tuab (qhov kev ntxhov siab axial) feem ntau me me heev. Raws li kev paub dhau los, cov khoom siv yuav muaj kev sib raug zoo Poisson hauv cov txheej txheem ntawm kev hloov pauv, tom qab ntawd yuav muaj kev ntswj ntawm qhov concentration ntawm kev hloov pauv, yog li nyob rau hauv qhov kev ua ntawm lub zog, ib qho bulge zoo li band yuav tshwm sim vim tsis ruaj khov.
LINBAY ROLL FORMING MACHINE pab pawg neeg muab kev daws teeb meem rau koj:
Thaum cov nthwv dej tawm los, peb tuaj yeem siv ntau lub rooj sib dhos los daws qhov teeb meem no; vim tias qhov dav ntawm ntug seem yuav cuam tshuam rau cov nthwv dej band, cov phaj nyias nyias yuav yooj yim rau cov nthwv dej strip dua li cov phaj tuab. Tus kws ua haujlwm tuaj yeem siv lub zog rau daim ntawv thaum tsim los txo cov nthwv dej strip.

2. Ntug nthwv dej
Cov nthwv dej ntug yog qhov tshwm sim feem ntau hauv cov txheej txheem tsim khoom ntawm cov tshuab dov. Muaj ob qho laj thawj rau nws.
(1) Ib yam li nthwv dej, vim tias cov khoom siv hauv seem nkhaus raug kev nyuaj siab transverse tensile, uas ua rau muaj kev nyuaj siab transverse tensile, thiab vim yog kev sib raug zoo Poisson, transverse shrinkage tshwm sim. Lub sijhawm no, ntug ntu yuav tshwm sim nthwv dej vim kev ntxhov siab shrinkage.
(2) Cov khoom siv tau pib ncab thiab txiav raws li qhov kev ua ntawm lub zog sab nraud kom ntev dua, thiab tom qab ntawd plastically deformed los ntawm kev nias thiab txiav, uas thaum kawg ua rau nthwv dej ntug.

LINBAY ROLL FORMING MACHINE pab pawg tshaj lij muab cov kev daws teeb meem rau koj: qhov dav ntawm ntug dav rau lub phaj tuab yog tsawg dua lossis ze rau 30 hli; Yog tias muaj nthwv dej thaum lub sijhawm ua cov txheej txheem dov, Linbay ntxiv tus lej ntawm cov sawv ntsug tsim kom txo nws.

3. Kev khoov ntev
Muaj ntau yam ua rau qhov khoov ntev hauv cov txheej txheem ntawm kev tsim cov tshuab dov, tab sis qhov tseem ceeb tshaj plaws yog tias ntug ntawm seem raug ncab mus rau hauv qhov kev coj mus ntev vim yog qhov kev ntxhov siab hauv cov txheej txheem ntawm kev khoov sab.
LINBAY ROLL FORMING MACHINE pab pawg kws tshaj lij muab cov kev daws teeb meem rau koj: ntxiv cov sawv ntsug tsim, txais yuav ua ntej khoov kom tsis txhob muaj qhov xwm txheej no, lossis kho qhov sib txawv ntawm cov menyuam kom txo lossis tshem tawm qhov khoov ntev.

4. Qhov teeb meem ntawm kev ruaj khov ntawm kev dovyog tias cov khoom siv feem ntau raug co hauv txoj kev sib tw thaum lub sijhawm tsim khoom. Qhov tseeb, ib pawg ntawm cov menyuam tsis sib xws. Sab laug dais lub zog loj thiab cov khoom txav mus rau sab xis; sab xis dais lub zog loj thiab cov khoom txav mus rau sab laug.

LINBAY YOB UA TSHUABCov kws tshaj lij pab pawg muab cov kev daws teeb meem rau koj: ua ntej, txheej nruab nrab hauv thaj chaw deformation raug suav kom raug, thiab qhov sib npaug ntawm cov menyuam ua haujlwm zoo. Qhov thib ob, thaj chaw tsis deformation yuav tsum tsis txhob raug nias ntau li ntau tau (xws li hauv qab ntawm txoj kev swb), thiab qhov sib txawv ntawm cov menyuam sab saud thiab sab qis yuav tsum khaws cia kom sib xws thaum lub sijhawm sib dhos. Thaum kawg, teeb tsa cov khoom siv qhia kom daim ntawv nyob hauv nruab nrab.
