Aluminium yog cov khoom siv ntau heev rau kev rho tawm thiab cov khoom lag luam uas ua rau nws zoo tagnrho rau kev sib sau thiab cov hlau los ntawm cov khoom sib txuas. Lub duction siab ntawm txhuas txhais tau tias cov hlau tuaj yeem tsim tau yooj yim rau kev siv ntau yam ntawm ib nrab ntawm cov hlau dog dig. Ob qho ntawm cov lus tseeb no txhais tau tias lub Extrusion Aluminium Processionats kuj siv hluav taws xob tsawg, uas txo cov cuab yeej thiab cov nqi tsim khoom. Thaum kawg, Aluminium kuj muaj lub zog siab rau qhov hnyav piv, ua rau nws xaiv zoo rau kev lag luam.
Raws li kev ua haujlwm ntawm cov txheej txheem Extrusion, zoo, yuav luag pom cov kab tuaj yeem tshwm sim ntawm cov npoo ntawm qhov profile. Qhov no yog los ntawm kev tsim ntawm cov cuab yeej ntsuas thaum lub sijhawm extrusion, thiab kev kho cov kev khomob ntxiv tuaj yeem sau tseg kom tshem cov kab no. Txhawm rau txhim kho saum npoo ua tiav ntawm cov haujlwm profile, ob peb theem saum npoo av xws li lub ntsej muag milling tuaj yeem ua tom qab lub ntsiab expusion ua txheej txheem. Cov kev ua haujlwm no tuaj yeem sau tseg txhawm rau txhim kho cov geometry ntawm saum npoo los txhim kho cov tshooj profile los ntawm kev txo cov profile roughness ntawm extruded profile. Cov kev kho no feem ntau tau teev nyob rau hauv cov ntawv thov uas tau ua tiav qhov kev xav tau lossis qhov chaw mating yuav tsum tau tswj kom nruj.
Peb feem ntau pom cov khoom seem nrog 6063-T5 / T6 lossis 6061-T4, thiab 6061 hauv lub cim txhuas, thiab T4 / T5 / T6 yog lub xeev ntawm Aluminium Profile. Yog li dab tsi yog qhov sib txawv ntawm lawv?
Piv txwv li: tsuas yog muab tso, 6061 cov profile txhuas muaj lub zog zoo dua thiab txiav kev ua tau zoo, nrog kev ua tau zoo, zoo weldability thiab corrosion tsis kam; 6063 Aluminium profile muaj cov khoom zoo dua, uas tuaj yeem ua kom cov khoom siv nrawm dua, thiab muaj zog dua, corrosion tsis kam thiab kub tsis kam.
T4 Xeev:
Kev Kho Mob + Ntuj Laus Kev Laus, uas yog tus txhuas profile yog txias tom qab extruder, tab sis tsis laus nyob rau hauv cov laus rauv. Aluminium profile uas tsis tau muaj hnub nyoog muaj lub hardness tsis muaj zog thiab muaj kev tiv thaiv zoo, uas yog qhov tsim nyog rau tom qab khoov thiab lwm yam deformation.
T5 State:
Kev Kho Mob + Kev Ua Tsis tiav Cov Laus, tom qab cua txias quenching, thiab tom qab ntawd hloov mus rau kev laus thaum 200 degrees rau 2-3 teev. Aluminium hauv lub xeev no muaj lub siab tawv thiab muaj qee yam ntawm deformability. Nws yog qhov feem ntau siv nyob rau hauv cov phab ntsa Rain.
T6 Xeev:
Kev Kho Mob + Tiav cov kev laus dag, uas yog, tom qab kev sib tw txias dua li T5 Kub, yog li kom ua tiav lub xeev nyuaj dua, uas yog qhov haum rau qee lub sijhawm Nrog rau cov kev xav tau zoo rau cov khoom siv tawv.
Cov khoom siv tshuab ntawm txhuas cov khoom siv ntawm cov khoom sib txawv thiab cov xeev sib txawv yog cov ncauj lus kom ntxaws hauv qab no:
Paib lub zog:
Nws yog cov qoob loo txwv ntawm cov ntaub ntawv hlau thaum lawv tawm los, uas yog, qhov kev ntxhov siab uas resusscation micro decormation. Txog cov khoom siv hlau tsis muaj txiaj ntsig, tus nqi ntxhov siab uas tsim cov txiaj ntsig 0.2% uas tsim los ua nws cov txiaj ntsig tsis pub dhau los yog kom muaj zog. Sab nraud yuam kev ntau dua qhov kev txwv no yuav ua rau cov seem rau qhov tsis tas mus li thiab tsis tuaj yeem rov qab los.
Lub zog tensile:
Thaum aluminium yields rau qee yam, nws muaj peev xwm tiv taus deformation nce dua vim yog cov nplej rov qab ntawm cov nplej sab hauv. Txawm hais tias qhov deformation loj hlob sai sai rau lub sijhawm no, nws tsuas tuaj yeem nce ntxiv nrog kev ntxhov siab kom txog thaum kev ntxhov siab nce qib siab tshaj plaws. Tom qab ntawd, lub peev xwm ntawm cov ntaub ntawv tiv thaiv kev tawm tsam yog txo qis, thiab muaj deformation loj dua li ntawm qhov tsis muaj zog tshaj plaws. Cov ntoo khaub lig-ntu ntawm cov hnoos qeev ntawm no shrinks sai sai, thiab caj dab tshwm sim kom txog thaum nws tawg.
Webster Hardness:
Lub ntsiab cai ntawm lub Webster Hardness yog kom siv lub siab quenched rab koob ntawm ib qho qauv hauv lub zog hauv qab ntawm 0.01mm raws li lub webster hardness chav. Lub hardness ntawm cov khoom yog inversely proportional rau qhov tob ntawm kev nkag mus. Tus ntoo ntiav rau kev nkag mus, siab dua lub hardness, thiab vice versa.
Yas Deformation:
Qhov no yog hom kev deformation uas tsis tuaj yeem rov zoo li tus kheej. Thaum cov khoom lag luam engineering thiab cov khoom siv tau ua tiav dhau ntawm kev tawm suab nrov, uas yog deformation lossis residual deformation lossis residual deformation yuav tshwm sim, uas yog kev deformation yas.
