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 mus txog 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 tus ntaus sib txawv thiab tsis tshwm sim hauv tib qhov chaw ntawm cov khoom siv raw khoom, tej zaum yuav ua rau cov khoom sib txawv. il.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 yog tuav ntawm qhov kos duab tuag thiab lub 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 ntawm stretch punch.Yog tias nws qis dhau, wrinkling yuav tshwm sim.

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 cov cuab yeej tsim tsis muaj zog txaus.Koj cov pwm khau looj plab hlaub yuav tsum tuab txaus los tiv thaiv lub rub tsis muaj buckling.Qhov kev txhawb nqa nyob rau hauv cov khau tuag yuav tsum yog cov khoom hlau, thiab cov ntawv qhia tuag yuav tsum loj txaus los tiv thaiv kev txav ntawm sab saum toj thiab hauv qab tuag thaum lub sij hawm ncab.
Tshawb xyuas koj cov xov xwm ib yam nkaus.Yog tias cov ntawv xov xwm hnav thiab sloppy, nws tsis muaj teeb meem yog tias koj lub cuab yeej muaj zog - koj yuav tsis ua tiav.Kuaj xyuas cov ntawv xovxwm kom paub tseeb tias tag nrho cov hlab ntsha ntev ntawm cov xovxwm yog qhov tseeb thiab square.Ua kom paub tseeb tias koj daim duab lubricant tau zoo lim thiab tswj xyuas, thiab tias cov cuab yeej siv nyiaj thiab lub nozzle txoj hauj lwm raug kho.Thiab xyuas kom meej tag nrho cov duab kos duab kos duab kos duab kos duab kos duab kos duab kos duab kos duab kos duab kos duab kos duab kos duab kos duab kos duab kos duab kos duab kos duab kos duab kos duab kos duab kos duab kos duab kos duab kos duab kos duab kos duab kos duab kos duab kos duab kos duab kos duab kos duab kos duab kos duab kos duab kos duab kos duab kos duab kos duab kos duab kos duab thiab kos duab kos duab kos duab kos duab kos duab thiab kos duab kos duab kos duab kos duab kos duab kos duab kos duab kos duab kos duab kos duab thiab kos duab kos duab kos duab thiab kos duab kos duab kos duab kos duab kos duab kos duab kos duab kos duab kos duab kos duab kos duab kos duab kos duab kos duab kos duab kos duab kos duab kos duab kos duab kos duab kos duab kos duab kos duab kos duab kos duab kos duab kos duab thiab kos duab kos duab. ;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.
