Sheet hlau fabrication yog ib tug txheej txheem uas muaj xws li hloov cov ntaub ntawv ca rau hauv ntau yam duab thiab cov qauv los ntawm ib tug series ntawm tshwj xeeb cov tswv yim thiab kev khiav hauj lwm. Kev nkag siab txog kev ua haujlwm ntawm cov ntawv hlau fabrication yuav tsum muaj kev saib xyuas ntawm cov txheej txheem tseem ceeb thiab cov thev naus laus zis koom nrog. Ntawm no yog cov ncauj lus kom ntxaws qhia txog yuav ua li cas sheet hlau fabrication ua haujlwm:
1. Kev xaiv khoom
Thawj kauj ruam hauv kev tsim cov ntawv hlau yog xaiv cov khoom tsim nyog. Cov khoom siv feem ntau muaj xws li steel (carbon steel thiab stainless hlau), txhuas, tooj liab, tooj dag, thiab ntau yam alloys. Kev xaiv ntawm cov khoom yog nyob ntawm cov yam ntxwv xws li lub zog, qhov hnyav, kev tiv thaiv corrosion, tus nqi, thiab cov kev cai tshwj xeeb ntawm cov khoom kawg.
2. Tsim thiab Kev Npaj
Ua ntej kev tsim khoom tiag tiag pib, kev tsim kom ntxaws thiab kev npaj yog qhov tseem ceeb. Cov kws tsim qauv thiab cov kws tsim qauv siv Computer-Aided Design (CAD) software los tsim cov qauv tsim thiab cov qauv ntawm qhov xav tau. Cov qauv tsim no qhia qhov ntev, kam rau ua, thiab lwm yam tseem ceeb. Cov theem tsim qauv tseem suav nrog kev txiav txim siab txoj hauv kev zoo tshaj plaws los txiav thiab tsim cov ntawv hlau kom txo cov khib nyiab thiab xyuas kom muaj kev ncaj ncees.
3. Txiav thiab Shearing
Txiav yog cov txheej txheem ntawm kev tshem tawm cov khoom siv ntau dhau los ntawm cov ntawv hlau los tsim cov duab uas xav tau. Muaj ntau ntau txoj hauv kev siv cov ntawv hlau fabrication:
Txiav: Qhov no suav nrog kev siv cov tshuab txiav loj los hla cov ntawv hlau raws txoj kab ncaj nraim. Shearing feem ntau yog siv los tsim cov duab plaub lossis square blanks.
Laser Txiav: Lub teeb laser yog siv los txiav cov duab thiab cov qauv rau hauv cov ntawv hlau. Laser txiav yog qhov tseeb heev thiab tuaj yeem tswj cov qauv tsim.
Dej dav hlau txiav: Lub siab - cov dej ntws sib xyaw nrog cov khoom abrasive yog siv los txiav cov hlau. Txoj kev no yog tsim los txiav cov nplooj ntawv tuab thiab muab cov npoo du.
Plasma Txiav: Lub teeb plasma melts thiab txiav los ntawm cov hlau siv lub siab -kub dav hlau ntawm cov roj ionized. Nws yog feem ntau siv rau txiav tuab steel nplooj ntawv.
4. Khoov thiab sib sau
Tom qab txiav, cov nplooj ntawv hlau tau zoo li tus yam xav tau los ntawm kev khoov thiab tsim cov txheej txheem:
Nias Nres: Cov tshuab no siv hydraulic lossis mechanical quab yuam los khoov cov ntawv hlau rau hauv cov ces kaum tshwj xeeb. Lub vojvoog khoov thiab lub kaum sab xis yog ua tib zoo tswj kom tsis txhob deformation lossis tawg.
Yob txoj kev: Cov ntawv hlau tau dhau los ntawm ntau cov chais kom maj mam khoov rau hauv cov duab nkhaus. Txoj kev no feem ntau yog siv los tsim cov qauv cylindrical lossis tubular.
Stretch forming: Cov ntawv hlau yog ncab tshaj qhov tuag los tsim cov duab nkhaus. Cov txheej txheem no feem ntau siv hauv kev lag luam aerospace los tsim cov khoom siv dav hlau.
5. Punching thiab Stamping
Punching thiab stamping yog cov txheej txheem siv los tsim cov qhov, qhov chaw, lossis cov duab tshwj xeeb hauv cov ntawv hlau:
xuas nrig ntaus: Cov cuab yeej xuas nrig yog siv los tsim cov qhov los yog txiav tawm los ntawm nias cov ntawv hlau tiv thaiv kev tuag. Txoj kev no yog tsim los tsim cov qhov me me lossis cov duab yooj yim.
Stamping: Qhov no suav nrog kev siv xovxwm stamping los tsim cov duab thiab cov qauv ntau dua. Cov ntawv hlau yog muab tso rau nruab nrab ntawm qhov tuag thiab xuas nrig ntaus, thiab cov xovxwm siv lub zog los tsim cov duab uas xav tau.
6. Vuam thiab koom ua ke
Txhawm rau sib sau ua ke ntau yam hlau, vuam thiab sib koom cov txheej txheem yog ua haujlwm:
Vuam: Cov txheej txheem vuam feem ntau suav nrog MIG (Metal Inert Gas) vuam, TIG (Tungsten Inert Gas) vuam, thiab qhov chaw vuam. Cov hau kev no siv cov cua sov los fuse cov hlau ua ke, tsim cov pob qij txha muaj zog thiab ruaj khov.
Riveting: Rivets yog siv los koom nrog cov khoom hlau los ntawm kev ntxig rau hauv qhov ua ntej -drilled qhov thiab tom qab ntawd deforming lub taub hau rivet kom ruaj cov khoom ua ke.
Fastening: Screws, bolts, thiab lwm yam fasteners yog siv los koom nrog cov khoom siv hlau yam tsis tau yaj cov hlau.
7. Nto Finishing
Tom qab cov txheej txheem fabrication yooj yim, nto xov yog feem ntau siv los txhim kho cov tsos, durability, thiab functionality ntawm hlau qhov chaw:
Painting thiab Txheej: Siv cov xim pleev xim, hmoov txheej, lossis lwm yam txheej txheej tiv thaiv kom tsis txhob xeb thiab txhim kho cov tsos.
Polishing thiab Buffing: Cov txheej txheem no tsim kom muaj lub ntsej muag du, ci ntsa iab, feem ntau siv rau kev kho kom zoo nkauj.
Anodizing: Feem ntau siv rau txhuas, anodizing tsim ib tug ruaj khov, corrosion-resistant oxide txheej ntawm cov hlau nto.
8. Kev Tswj Xyuas Zoo thiab Kev Tshawb Fawb
Kev tswj kom zoo yog qhov tseem ceeb ntawm kev tsim cov ntawv hlau. Fabricated qhov chaw raug tshuaj xyuas siv cov cuab yeej xws li calipers, micrometers, thiab Coordinate Measuring Machines (CMM) kom ntseeg tau tias lawv ua tau raws li qhov ntev thiab qhov ntev. Txhua qhov tsis xws lossis qhov sib txawv raug kho kom ntseeg tau tias cov khoom kawg ua tau raws li cov qauv xav tau.
Xaus
Sheet hlau fabrication yog ib qho nyuaj tab sis muaj txiaj ntsig zoo uas ua ke nrog cov thev naus laus zis siab heev nrog kev txawj ntse. Los ntawm kev nkag siab txog kev ua haujlwm ntawm kev txiav, khoov, sib sau, vuam, thiab ua tiav, cov chaw tsim khoom tuaj yeem tsim ntau yam ntawm cov khoom siv hlau zoo nrog qhov tseeb thiab kev ntseeg tau. Qhov kev ua tau zoo no ua rau cov ntawv hlau tsim cov txheej txheem tseem ceeb hauv kev lag luam xws li tsheb, aerospace, electronics, thiab kev tsim kho.
