Cov Kev Xav Tau Rau Cov Khoom Siv Stamping yog
Jan 05, 2024| Qhov saum npoo thiab sab hauv cov khoom ntawm cov ntawv stamping muaj qhov cuam tshuam zoo rau qhov zoo ntawm cov khoom stamped. Cov kev xav tau rau cov khoom siv stamping yog:
① Lub thickness yog meej thiab sib xws. Stamping pwm yog qhov tseeb thiab muaj qhov khoob me me. Cov thickness ntau dhau ntawm daim ntawv yuav ua rau kom lub zog deformation, ua rau cov khoom siv jamming, thiab tseem ua rau tuag tawg. Ib daim ntawv nyias dhau lawm yuav cuam tshuam rau qhov zoo ntawm cov khoom tiav, thiab tej zaum yuav ua rau tawg thaum lub sij hawm sib sib zog nqus nqus.
②Qhov saum npoo yog du thiab huv, tsis muaj pob, nti, khawb, tawg nto, thiab lwm yam. Txhua qhov chaw tsis xws luag yuav nyob twj ywm rau ntawm qhov chaw ua haujlwm tiav, thiab cov kab nrib pleb yuav nthuav dav tob thiab dav thaum khoov, kos duab, tsim thiab lwm yam txheej txheem, ua rau seem.
③ Lub zog tawm los yog sib xws thiab tsis muaj kev taw qhia pom tseeb. Anisotropy (saib cov ntawv yas deformed thaum lub sij hawm stamping txheej txheem xws li kos duab, flanging, bulging, thiab lwm yam, vim qhov tshwm sim ntawm anisotropic yielding nyob rau hauv sequence, tus nqi ntawm cov yas deformation yog inconsistent, uas yuav ua rau uneven deformation thiab invalid forming. cov khoom seem.
④ High uniform elongation. Hauv kev sim tensile, elongation ua ntej lub caj dab tshwm sim pib tshwm sim ntawm cov qauv hu ua uniform elongation. Thaum lub sij hawm sib sib zog nqus nqus, qhov deformation ntawm ib cheeb tsam ntawm daim ntawv tsis tuaj yeem tshaj qhov sib txuas ntxiv ntawm cov khoom, txwv tsis pub deformation yuav tshwm sim.
⑤ Qhov piv ntawm cov tawm los rau lub zog yog tsawg. Qhov piv ntawm cov khoom siv tawm los txwv rau nws lub zog txwv yog hu ua yield-strength ratio. Qhov tsis tshua muaj txiaj ntsig-rau-lub zog piv tsis tuaj yeem tsuas yog txo cov deformation tsis kam, tab sis kuj txo qhov nyiam ntawm wrinkling thaum lub sij hawm sib sib zog nqus nqus, txo tus nqi ntawm rebound tom qab khoov, thiab txhim kho qhov tseeb ntawm khoov qhov chaw.
⑥ Tsawg ua haujlwm hardenability. Kev ua hauj lwm hardening uas tshwm sim tom qab txias deformation yuav ua rau kom lub deformation tsis kam ntawm cov khoom thiab ua rau deformation nyuaj, yog li cov phaj uas tsis tshua muaj hardening index feem ntau yog siv. Txawm li cas los xij, cov ntaub ntawv uas muaj qhov ntsuas siab hardening muaj qhov zoo ntawm cov yas deformation stability (uas yog, cov yas deformation kuj zoo ib yam) thiab tsis tshua muaj kev tawg hauv zos.
Hauv kev tsim khoom tiag tiag, cov txheej txheem kev sim zoo ib yam li cov txheej txheem stamping, xws li kev ntsuas kev sib sib zog nqus nqus, kev ntsuas kev ua tau zoo, thiab lwm yam, feem ntau yog siv los kuaj cov khoom siv stamping kom ntseeg tau tias cov khoom tiav tiav thiab tus nqi siab.
