Khoom siv rau Stamped Parts
Qhov saum npoo thiab sab hauv ntawm cov ntawv hlau siv rau stamping muaj qhov cuam tshuam loj rau qhov zoo ntawm cov khoom tiav tiav. Cov kev xav tau rau cov khoom siv stamping yog:
① Precise thiab uniform thickness. Stamping tuag yog meej nrog me me clearances. Cov ntawv tuab ntau dhau ua rau lub zog deformation, ua rau jamming thiab txawm tawg qhov tuag; Cov ntawv tuab tsis txaus cuam tshuam rau cov khoom tiav tiav thiab tuaj yeem ua rau tawg thaum sib sib zog nqus nqus.
② Smooth nto, tsis muaj blemishes, nti, khawb, thiab nto tawg. Tag nrho cov defects yuav nyob twj ywm rau saum npoo ntawm lub workpiece tiav. Cov kab nrib pleb tuaj yeem nthuav dav dua thiab dav dua thaum khoov, sib sib zog nqus nqus, thiab tsim cov txheej txheem, ua rau cov khoom seem.
③ Uniform yield zog nrog tsis pom tseeb directionality. Anisotropy (saib: Nyob rau hauv cov txheej txheem ntawm kev sib sib zog nqus kos duab, flanging, bulging, thiab lwm yam., ntawm cov ntawv hlau nyob rau hauv cov yas deformation, lub sij hawm sib txawv ntawm yielding nyob rau hauv txhua txoj kev coj mus rau inconsistent yas deformation, ua rau uneven deformation, tsis raug tsim, thiab ua rau cov khoom puas los yog khoom seem.)
④ High uniform elongation. Hauv kev ntsuam xyuas tensile, qhov elongation ntawm cov qauv ua ntej qhov tsos ntawm caj dab yog hu ua uniform elongation. Thaum lub sij hawm sib sib zog nqus nqus, qhov deformation nyob rau hauv ib cheeb tsam ntawm daim ntawv hlau yuav tsum tsis txhob ntau tshaj li niaj hnub elongation ntau yam ntawm cov khoom; txwv tsis pub, tsis sib xws deformation yuav tshwm sim.
⑤ Tsawg yield zog piv. Qhov piv ntawm lub zog tawm los mus rau qhov kawg tensile lub zog ntawm cov khoom yog hu ua yield zog piv. Lub zog tsis tshua muaj zog tsis yog tsuas yog txo cov deformation tsis kam, tab sis kuj txo cov kev xav ntawm wrinkle thaum lub sij hawm sib sib zog nqus nqus, txo cov springback tom qab khoov, thiab txhim kho qhov tseeb ntawm khoov qhov chaw.
⑥ Tsawg ua hauj lwm hardening. Ua hauj lwm hardening uas tshwm sim tom qab txias deformation tsub kom lub deformation tsis kam ntawm cov khoom, ua ntxiv deformation nyuaj. Yog li ntawd, cov ntawv hlau uas muaj qhov ntsuas qis hardening feem ntau yog siv. Txawm li cas los xij, cov ntaub ntawv uas muaj qhov siab hardening Performance index muaj qhov zoo ntawm cov yas deformation stability (piv txwv li, ntau yam yas deformation) thiab tsis tshua muaj kev cuam tshuam hauv zos tensile cracking.
