Dab tsi yog 20mm Aluminium Phaj?
Lub phaj txhuas yog ib lub tiaj- cov khoom uas muaj lub thickness saum toj no 6 hli, thiab 20 hli yog ib qho uas feem ntau thov hnyav- ntsuas qhov ntev rau cov qauv thiab kev siv. Nws yog tsim los ntawm kub dov ntawm DC cam khwb cia slabs, uas muab ib tug ntom nyob rau hauv cov qauv, uniform mechanical zog thiab zoo flatness. Cov phaj yog ib txwm muab rau hauv H112 lossis annealed mob rau 5xxx series, hauv T6 mob rau 6xxx series, thiab ntau yam tempers rau 1xxx thiab 3xxx series.
Vim tias nws cov tuab, 20 hli phaj coj txawv ntawm daim ntawv: nws yog siv tsuas yog rau kev thauj khoom -cov kabmob thiab hnav- cov khoom tiv thaiv tsis yog rau kev khoov thiab sib sau. Dimensional tswj, flatness thiab sab hauv soundness yog li ntawd tseem ceeb tshaj li cov tshuaj pleev ib ce nyob rau hauv feem ntau daim ntaub ntawv.
Alloy xaiv los ntawm daim ntawv thov
1xxx series, suav nrog 1050, 1060 thiab 1100, muaj purity siab, zoo corrosion kuj thiab zoo hluav taws xob conductivity, tab sis kuj tsis tshua muaj zog. Cov qib no yog siv qhov formability los yog conductivity yog qhov tseem ceeb thiab mechanical loads yog me me.
3xxx series, coj los ntawm 3003 thiab 3004, muab lub zog ntau dua li cov ntshiab txhuas nrog corrosion kuj zoo thiab weldability, thiab yog tus nqi -kev xaiv zoo rau kev tsim, tso tsheb hlau luam thiab ducting.
5xxx series, tshwj xeeb tshaj yog 5052, 5083 thiab 5086, yog cov tsev neeg ntau tshaj plaws rau 20 hli daim hlau hauv kev pabcuam kev ua haujlwm. Cov aluminium-magnesium alloys ua ke nruab nrab mus rau lub zog siab nrog cov dej hiav txwv zoo heev thiab atmospheric corrosion kuj, thiab lawv tau siv dav hauv kev tsim cov nkoj, cov qauv sab nrauv, cov hlab ntsha siab, cov tso tsheb hlau luam thiab cov khoom siv thauj khoom. Qib xws li 5083 tau teev nyob rau hauv kev faib cov cai rau kev tsim kho marine.
Lub 6xxx series, tshwj xeeb tshaj yog 6061 thiab 6063, muaj cua sov- kho lub zog nrog kev ua haujlwm zoo. A 20 hli 6061-T6 phaj yog ib qho kev xaiv rau lub tshuab thav duab, jigs, pwm thiab cov khoom siv hluav taws xob dav dav, thiab anodizes zoo rau kev siv vaj tsev.
8xxx series, suav nrog 8011 thiab 8079, tsis tshua muaj nyob ntawm 20 mm thickness thiab feem ntau yog siv rau ntim tshwj xeeb lossis daim ntawv thov capacitor.
Dimensional thiab Tolerance Considerations
20 hli daim hlau muaj nyob rau hauv dav ntawm 1000 hli, 1200 hli, 1250 hli, 1500 hli thiab dav, thiab nyob rau hauv ntev ntawm 2000 hli mus txog 6000 hli los yog ntau tshaj. Standard thickness kam rau ua rau 20 hli phaj yog feem ntau ntxiv los yog rho tawm 0.5 hli nyob rau hauv EN 485-4 los yog cov coj kam rau ua chav kawm ntawm ASTM B209, thiab flatness yog tswj kom haum laser txiav thiab machining. Thaum lub phaj yuav raug machined mus rau ib tug zaum kawg thickness los yog siv nyob rau hauv ib tug precision los ua ke, qhia kom meej lub nruj dua cov chav kawm ntawv thiab paub meej tias cov flatness yuav tsum tau nrog tus neeg muag khoom.
Kev kho deg thiab ua tiav
Mill tiav yog tus qauv thiab pheej yig tshaj plaws rau cov qauv phaj. Rau kev siv vaj tse lossis kho kom zoo nkauj, lub phaj tuaj yeem ua anodized, pleev xim rau PVDF lossis polyester coatings, txhuam los yog polished. Rau kev pabcuam hauv hiav txwv thiab tshuaj lom neeg, lub ntuj oxide txheej ntawm 5xxx alloys feem ntau yog txaus, thaum 6xxx qib tuaj yeem ua anodized los txhim kho kev hnav thiab corrosion. Kev tiv thaiv zaj duab xis los yog ntawv interleaving yog siv rau cov chaw uas yuav tsum tuaj txog tsis muaj khawb.
Ua thiab Machining Notes
20 hli txhuas phaj feem ntau yog txiav los ntawm sawing, waterjet, plasma lossis laser txiav. Laser thiab waterjet tsim cov npoo huv tshaj plaws nrog cov cua sov tsawg tshaj plaws - thaj chaw cuam tshuam, thaum lub plasma yuav tsum tau ntxuav ntug ua ntej vuam. Drilling thiab tapping yog ncaj nraim nrog cov cuab yeej ntse carbide thiab cov cua txias tsim nyog. Rau vuam, 5xxx daim hlau siv cov khoom sib txuam xws li ER5356 lossis ER5183, thaum 6061-T6 siv ER4043 lossis ER5356 nyob ntawm qhov yuav tsum tau muaj zog; Cov ntu hnyav yuav xav tau preheat thiab tswj kev sib tshuam kub kom tsis txhob tawg.
FAQ
Q: Qhov twg aluminium alloy zoo tshaj rau 20mm phaj hauv dej hiav txwv?
5083 thiab 5086 yog cov qauv marine qib . 5083 muaj zog dua, thaum 5086 muab qhov sib npaug zoo ntawm lub zog thiab weldability; ob qho tib si tau txais los ntawm cov koom haum kev faib tawm loj rau cov nkoj thiab cov qauv hauv ntug dej hiav txwv.
Q: Lub 20mm aluminium phaj puas tuaj yeem khoov lossis tsim?
Kev khoov yog ua tau tab sis yuav tsum muaj cov cuab yeej muaj zog thiab dav dav khoov radii, feem ntau ntau zaus ntawm cov tuab. Rau cov khoom tsim hnyav, ib daim ntawv nyias nyias lossis cov khoom sib txawv yog feem ntau pheej yig dua.
Q: Ntau npaum li cas 20mm aluminium phaj hnyav?
Aluminium muaj qhov ntom ntom ntawm 2.7 g / cm³, yog li 20 hli phaj hnyav kwv yees li 54 kg ib square meter, txog ib feem peb ntawm qhov hnyav ntawm lub phaj hlau ntawm tib qhov loj.
Q: Puas yog 6061-T6 lossis 5083 qhov kev xaiv zoo dua rau lub tshuab thav duab?
6061-T6 feem ntau yog nyiam rau lub tshuab thav duab vim nws lub zog ntau dua, zoo machinability thiab ruaj khov qhov ntev tom qab kev kho cua sov . 5083 yog xaiv thaum lub thav duab yuav fim corrosive lossis marine ib puag ncig.
Q: Dab tsi yog tus qauv xa tuaj rau 20mm phaj?
Thickness kam rau ua yog feem ntau ntxiv lossis rho tawm 0.5 hli raws li EN 485-4 thiab cov chav kawm sib xws ntawm ASTM B209; nruj tolerances muaj nyob rau ntawm kev thov rau machined los yog precision Cheebtsam.
Q: Puas yog lub phaj puas xav tau ntawv pov thawj rau kev siv nkoj tsim khoom?
Yog lawm. Rau kev siv dej hiav txwv lub phaj yuav tsum tau muab nrog daim ntawv pov thawj zeb thiab, thaum xav tau, kev pom zoo ntawm pawg neeg xws li ABS, DNV, LR lossis CCS rau qib tshwj xeeb thiab kev kub ntxhov.
