Vim li cas 8079 Foil siv rau kev kos duab sib sib zog nqus
Kev sib sib zog nqus yog ib daim ntawv- txheej txheem tsim uas lub tiaj tiaj tiaj raug thawb mus rau hauv qhov tuag kab noj hniav los tsim lub khob lossis lub plhaub, thiab cov khoom yuav tsum ncab, ntws thiab compressed yam tsis muaj tearing lossis wrinkling. 8079 yog aluminium- hlau- silicon foil alloy nrog kev ua tib zoo sib npaug uas ua rau nws tsim nyog rau qhov kev thov no. Nws yog dav siv los kos cov thawv ntim khoom noj, kaw, hlwv - pob hau thiab lwm yam khoom siv qhov ntsuas nyias, kev ua haujlwm tsis zoo thiab kev txhim khu kev qha yog txhua yam yuav tsum tau ua.
Microstructure thiab Formability
Kev tsim tus cwj pwm ntawm 8079 ntawv ci yog tswj los ntawm nws cov qauv nplej thiab kev ntxhib los mos, uas yog tsim los ntawm kev sib tw txias thiab kev sib tsoo. Ib qho zoo, recrystallized grain qauv nyob rau hauv thaj tsam li ntawm 5-15 microns txhawb homogeneous deformation thaum lub sij hawm kos duab: ntau nplej koom nyob rau hauv lub ntws, lim yog faib tusyees, thiab localized thinning yog txo. Qhov kev ntxhib los mos ntawm cov ntawv ci kuj tseem ceeb heev, vim tias nws tswj tau yooj yim npaum li cas cov khoom ntws mus rau hauv qhov tuag thiab yuav ua li cas nws coj txawv txawv. Kev sib npaug ntawm cov nplej loj thiab kev ntxhib los mos muab cov ntawv ci sib xyaw ua ke ntawm lub zog rau lub khob phab ntsa thiab ductility rau thaj tsam flange, uas yog tus yuam sij rau qhov tsis xws luag-dawb sib sib zog nqus kos duab.
Mechanical Properties Uas Tseem Ceeb
Nyob rau hauv ib txwm mos los yog maj mam ua hauj lwm- hardened tej yam kev mob, 8079 ntawv qhia tawm lub zog nyob rau hauv thaj tsam ntawm kwv yees li 90-120 MPa thiab tensile zog ntawm 140-180 MPa, nrog uniform elongation saum toj no 20% nyob rau hauv lub tag nrho annealed lub xeev. Ob qhov formability tsis yog qhov tseem ceeb tshwj xeeb rau kev kos duab sib sib zog nqus. Tus nqi r-tus nqi, lossis Lankford coefficient, piav qhia txog qhov tsis kam ua kom nyias nyias hauv cov thickness; 8079 ntawv ci tsim siab r- cov nqi, uas txhais tau hais tias cov khoom nyiam ntws hauv - dav hlau ntau dua li nyias, raws nraim li lub khob phab ntsa xav tau. Lub n-tus nqi, lossis strain- hardening exponent, tswj cov khoom siv zog li cas thaum nws deforms, uas ua rau qeeb strain localization thiab pab faib cov duab kos. Ua ke, tus nqi siab r- tus nqi, tsim nyog n-tus nqi thiab huv si, qis-roughness nto tso cai rau 8079 ntawv ci los kos rau hauv lub khob qhov tob uas tsis ua haujlwm.
Nto Zoo thiab Nws Lub Luag Haujlwm
Deg mob yog txiav txim siab nyob rau hauv sib sib zog nqus daim duab vim hais tias cov ntawv ci slides tiv thaiv lub punch thiab tuag nyob rau hauv siab. Qhov chaw huv si uas tsis tshua muaj roughness, feem ntau qis dua Ra 0.2 microns, ua kom muaj kev sib txhuam qis thiab tiv thaiv galling thiab tearing hauv zos. Kev sib kis ntawm qhov chaw xws li dov roj residues, plua plav lossis oxide khib nyiab cuam tshuam cov roj nplaum zaj duab xis thiab tuaj yeem ua rau cov kab nrib pleb, yog li ntawv ci rau kos duab sib sib zog nqus yuav tsum tau ua thiab khaws cia nrog kev saib xyuas. Cov txheej txheej ntuj oxide nyias ntawm lub ntsej muag txhuas feem ntau yog qhov zoo dua: nws txais kev tsim cov roj nplua nyeem zoo thiab, nrog rau txoj cai chemistry, muab cov ciam teb zoo lubrication yam tsis cuam tshuam nrog kev sib txuas tom ntej lossis luam ntawv.
Lubrication thiab txheej txheem tswj
Lubrication yog tus yuam sij rau kev ua kom sib sib zog nqus nqus. Kev tsim cov roj nplua nyeem uas tsim nyog viscosity thiab siab tsis kam yog siv sib npaug rau qhov khoob, feem ntau los ntawm cov menyuam los yog tshuaj tsuag. Cov roj nplua nyeem yuav tsum txo qis kev sib txhuam ntawm qhov khoob - tuav thiab tuag radii thaum tso cai rau cov khoom siv khiav, thiab nws yuav tsum sib haum nrog cov ntawv ci nto thiab nrog kev tu hauv qab los yog ua tiav cov kauj ruam. Kev tswj qhov kub thiab txias yog qhov tseem ceeb sib npaug: kos duab ntawm lossis ze ntawm chav tsev kub khaws cov khoom hauv nws lub zog thiab lub qhov rais ductility, thaum cov cua kub ntau dhau los ntawm siab -kev deformation ceev tuaj yeem ua rau cov khoom muag muag thiab ua rau qhov tsis txaus ntseeg. Cov txheej txheem tsis tu ncua, suav nrog qhov khoob - tuav lub zog, punch ceev thiab lubrication kom muaj nuj nqis, yog dab tsi tig cov ntawv ci uas muaj peev xwm nkag mus rau hauv cov khoom siv txhim khu kev qha.
Cov ntawv thov thiab xaiv Cov Lus Cim
8079 sib sib zog nqus- daim ntawv kos duab yog siv rau puag ncig thiab lub thawv kos duab, lub tais hau, kaw thiab cov chaw muag tshuaj lossis cov khoom ntim khoom noj uas cov duab kos yuav tsum tuav lub foob thaiv. Thaum xaiv cov ntawv ci rau daim ntawv thov kos duab, qhia qhov ntsuas, qhov kub thiab txias, qhov chaw tiav thiab lubrication, thiab siv tau cov khoom siv nrog kev sim ua ntej tsim khoom vim tias qhov sib txawv me me ntawm cov cuab yeej, nias ceev thiab roj nplua nyeem hloov cov ntawv ci zoo. Ua hauj lwm nrog lub zeb kom phim cov yam ntxwv ntawm cov ntawv ci rau cov cuab yeej tiag tiag yog txoj hauv kev txhim khu kev qha tshaj plaws rau qhov tsis xws luag - dawb qhov chaw.
FAQ

8079 ntawv ci tuaj yeem sib sib zog nqus nqus hauv lub xeev siab muag?
Yog lawm, tus mob annealed mos muaj qhov siab tshaj plaws ductility thiab feem ntau yog siv rau cov khob sib sib zog nqus; nyuaj tempers yog siv qhov twg ib feem yuav tsum tiv thaiv tuav loads tom qab sib sau.
Vim li cas kuv daim ntawv kos duab qhia pom wrinkles ntawm flange?
Wrinkling feem ntau yog ib qho teeb meem ntawm cov txheej txheem: ntau dhau lawm - tus tuav quab yuam yog xav tau, los yog qhov khoob - tuav lub siab yog qis dhau, lub roj nplua nyeem tsis raug, lossis lub cuab yeej radii me dhau rau cov khoom ntws.
r-tus nqi ntawm 8079 foil txiav txim siab li cas?
Tus nqi r- yog ntsuas nyob rau hauv ib qho kev ntsuas tensile los ntawm kev sib piv dav strain rau thickness strain hauv cheeb tsam yas; Cov nqi siab dua qhia tau zoo dua rau kev ua kom nyias nyias thiab zoo dua drawability.
Puas yog 8079 foil xav tau kev tuav tshwj xeeb ua ntej kos duab?
Qhov saum npoo yuav tsum tau ceev kom huv si thiab qhuav, tsis muaj roj paug thiab khawb, thiab yob yuav tsum tau muab khaws cia rau hauv lawv cov ntaub thaiv kom txog thaum siv los khaws cov khoom zoo.
Yuav kos 8079 qhov chaw tuaj yeem luam lossis coated?
Yog lawm, kos qhov chaw tuaj yeem luam tawm, lacquered lossis laminated tom qab tsim, muab qhov chaw huv si thiab cov txheej txheem tiav yog sib xws nrog cov ntawv ci thiab cov roj nplua nyeem.
