Daim hlau
Kev siv thev naus laus zis, cov ntawv hlau tseem tsis tau muaj cov ntsiab lus ua tiav. Raws li cov lus txhais hauv phau ntawv xov xwm txawv teb chaws, nws tuaj yeem txhais tau tias: Cov ntawv hlau yog cov txheej txheem ua haujlwm txias rau cov ntawv hlau (feem ntau hauv qab 6 hli), suav nrog shearing, xuas nrig ntaus / txiav / sib xyaw, folding, riveting, splicing, forming ( xws li tsheb lub cev), thiab lwm yam. Nws zoo kawg nkaus feature yog tias lub thickness ntawm tib seem yog tib yam.
Cov yam ntxwv txheej txheem
Sheet hlau muaj cov yam ntxwv ntawm lub teeb yuag, siab zog, hluav taws xob conductivity (tuaj yeem siv rau electromagnetic shielding), tus nqi qis, thiab kev ua haujlwm zoo. Nws tau siv dav hauv cov khoom siv hluav taws xob, kev sib txuas lus, kev lag luam tsheb, khoom siv kho mob thiab lwm yam. Hauv cov rooj plaub hauv computer, xov tooj ntawm tes, thiab MP3s, cov ntawv hlau yog qhov tseem ceeb. Raws li daim ntawv thov ntawm cov ntawv hlau ua ntau dua thiab dav, kev tsim cov ntawv hlau tau dhau los ua ib feem tseem ceeb ntawm cov txheej txheem tsim khoom. Mechanical engineers yuav tsum paub txog kev tsim cov txuj ci ntawm cov ntawv hlau, kom cov ntawv hlau tsim tuaj yeem ua tau raws li qhov yuav tsum tau ua ntawm cov khoom. Kev ua haujlwm thiab qhov xav tau, tab sis kuj ua rau lub stamping tuag yooj yim rau kev tsim khoom thiab tus nqi qis.
Lub hom phiaj tseem ceeb
Muaj ntau cov ntaub ntawv hlau uas haum rau kev ua haujlwm stamping. Cov ntaub ntawv hlau siv dav hauv kev lag luam hluav taws xob thiab hluav taws xob muaj xws li:
⒈ Cov ntawv txias txias SPCC SPCC hais txog qhov txuas txuas ntxiv ntawm cov hlau ingots rau hauv cov hlau coils lossis cov nplooj ntawv uas xav tau tuab los ntawm lub tshuab txias txias. SPCC nto tsis muaj kev tiv thaiv, nws yog ib qho yooj yim rau oxidized thaum raug huab cua, tshwj xeeb tshaj yog nyob rau hauv ib qho chaw ntub, oxidation ceev ceev, tsaus liab xeb tshwm, thiab nto yuav tsum tau pleev xim rau, electroplated los yog lwm yam kev tiv thaiv thaum nyob rau hauv siv.
⒉ Galvanized steel ntawv SECC Lub substrate ntawm SECC yog ib tug dav dav-kuav los tiag steel kauj, uas yog ib tug electro-galvanized khoom tom qab degreasing, pickling, electroplating thiab ntau yam kev kho mob tom qab ib tug tas mus li electro-galvanizing ntau lawm kab. SECC tsis tsuas yog muaj cov khoom siv kho tshuab thiab cov txheej txheem zoo sib xws ntawm cov ntawv txias txias-kuav los tiag, tab sis kuj muaj kev tiv thaiv corrosion zoo dua thiab zoo nkauj zoo nkauj. Nws muaj kev sib tw zoo thiab kev hloov pauv hauv kev ua lag luam ntawm cov khoom siv hluav taws xob, cov khoom siv hauv tsev thiab cov rooj tog zaum. Piv txwv li, cov ntaub ntawv siv computer feem ntau yog SECC.
⒊ Kub-dip galvanized steel ntawv SGCC Kub-dip galvanized steel kauj yog hais txog cov khoom ua tiav tom qab kub dov los yog txias dov, tom qab ntxuav, annealing, thiab muab tso rau hauv ib lub molten zinc da dej nrog kub txog 460. degree C, yog li ntawd cov ntawv hlau yog plated nrog zinc txheej ces tempered, leveled thiab tshuaj kho. SGCC cov khoom yog ib qho nyuaj tshaj li SECC cov khoom, muaj cov ductility tsis zoo (tsis txhob sib sib zog nqus kos duab), zinc txheej tuab thiab weldability tsis zoo.
⒋ Stainless hlau SUS301 Cov ntsiab lus ntawm Cr (chromium) yog qis dua li ntawm SUS304, thiab corrosion kuj tsis zoo, tab sis nws tuaj yeem tau txais lub zog tensile zoo thiab hardness tom qab ua haujlwm txias, thiab muaj elasticity zoo. Nws feem ntau yog siv rau shrapnel springs thiab anti-EMI.
⒌ Stainless hlau SUS304 yog ib qho ntawm feem ntau siv stainless hlau. Vim nws muaj Ni (nickel), nws yog nplua nuj nyob rau hauv corrosion kuj thiab kub tsis kam tshaj hlau uas muaj Cr (chromium). Nws muaj cov khoom siv zoo heev, tsis muaj kev kho cua sov, tsis muaj elasticity. .
