Thaum tsim nyob rau hauv ib tug zuj zus tuag, cov neeg tuav lub siab dawb paug, siab tej yam kev mob, thiab cov ntaub ntawv raw tag nrho cov muaj feem xyuam rau lub peev xwm kom tau raws li stretch tshwm sim tsis wrinkling.
Q: Peb tab tom kos lub khob los ntawm qib 304 stainless hlau.Ntawm thawj zaug ntawm peb qhov kev vam meej tuag, peb kos txog li 0.75 ntiv tes sib sib zog nqus.Thaum kuv txheeb xyuas qhov tuab ntawm flange perimeter ntawm qhov khoob, qhov sib txawv ntawm ib sab tuaj yeem siab li 0.003 ntiv tes.Txhua qhov ntaus sib txawv thiab tsis tshwm sim nyob rau hauv tib qhov chaw ntawm raw khoom, tej zaum nws yuav ua tau. coil.Yuav ua li cas peb thiaj li tau txais lub khob zoo li qub tsis muaj wrinkling?
A: Kuv pom koj cov lus nug nce ob nqe lus nug: thawj zaug, qhov kev hloov pauv koj tau txais hauv cov txheej txheem rho npe, thiab thib ob, cov ntaub ntawv raw thiab lawv cov specifications.
Thawj lo lus nug cuam tshuam nrog cov cuab yeej tsim tsim qhov tsis zoo, yog li cia peb saib cov hauv paus.Intermittent wrinkling thiab post-draw thickness hloov ntawm khob flanges qhia tsis txaus tooling blanks nyob rau hauv koj qhov kev vam meej tuag qhov chaw nres tsheb.Yog tsis pom koj tus qauv tuag, kuv yuav tsum xav tias koj kos punch thiab tuag radii thiab lawv qhov sib txawv raws li tag nrho cov qauv tsim parameters.
Hauv kev sib sib zog nqus nqus, qhov khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob qhov rub ntawm stretch punch.Yog tias nws qis dhau, wrinkling yuav tshwm sim.
Nws muaj qhov txwv ntawm lub plhaub taub thiab lub qhov khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob. nyuaj nce tom qab tsim tiav).
Qhov siab ntawm qhov siab p yog 2.5 N / mm2 rau hlau, 2.0 txog 2.4 N / mm2 rau tooj liab alloys thiab 1.2 txog 1.5 N / mm2 rau txhuas alloys.
Variations nyob rau hauv flange thickness kuj qhia tau hais tias koj lub cuab tam tsim tsis muaj zog txaus.Koj cov pwm khau looj plab hlaub yuav tsum tuab txaus los tiv thaiv lub rub tsis buckling.Qhov kev txhawb nqa nyob rau hauv lub hauv paus tuag yuav tsum yog cov khoom hlau, thiab cov cuab yeej qhia pins yuav tsum loj txaus los tiv thaiv ib qho kev txav ntawm sab saum toj thiab hauv qab cov cuab yeej thaum ncab.
Txheeb xyuas koj cov xov xwm dhau.lawv cov geometry thiab nto tiav yuav tsum zoo meej.
Tsis tas li ntawd, thaum cov neeg siv khoom nyiam saib 304L thiab tus qauv 304 raws li kev hloov pauv, 304L yog qhov kev xaiv zoo dua rau kev kos duab.L sawv cev rau cov pa roj carbon tsawg, uas muab 304L lub zog tawm ntawm 0.2% ntawm 35 KSI thiab 304 ntawm 0.2% ntawm 42 KSI.Nrog rau 16% lub zog ntawm kev tsim Lield, txo qis hauv 16% kev tsim tawm thaum tsim kom muaj zog. shape.Nws yooj yim dua rau siv.
