Aluminium extrusion yog ntau yam txheej txheem tsim khoom uas tau hloov pauv ntau yam kev lag luam, los ntawm kev tsim kho mus rau aerospace. Txoj kev no ntawm shaping txhuas rau hauv tej profiles tau nrov zuj zus vim nws efficiency, nqi-effectiveness, thiab cov khoom tshwj xeeb nws imparts rau cov khoom kawg.
Cov txheej txheem Aluminium Extrusion Manufacturing yog ib qho kev sib xyaw ua ke ntawm engineering thiab metallurgy. Ntawm nws cov tub ntxhais, nws yuav tsum yuam kom rhuab aluminium los ntawm kev tuag nrog rau ib qho kev hla -sectional profile. Cov txheej txheem no tuaj yeem muab faib ua ob peb kauj ruam tseem ceeb:
1. Kev Npaj Billet: Cov txheej txheem pib nrog cov khoom siv txhuas lub tog raj kheej hu ua billet. Qhov no billet yog preheated rau qhov kub uas nws yuav ua tau zoo tab sis tsis molten, feem ntau ntawm 800℃F txog 925℃F (427℃rau 496℃).
2. Kev Npaj Tuag: Ib txhij, ib lub steel tuag nrog tus ntoo khaub lig xav tau -sectional shape yog npaj thiab preheated.
3. Extrusion: Lub rhuab billet yog muab tso rau hauv ib lub thawv thiab thawb los ntawm kev tuag siv hydraulic ram. Raws li cov txhuas raug yuam los ntawm qhov tuag, nws yuav siv sij hawm rau qhov zoo ntawm qhov tuag qhov qhib.
4. Txias: Raws li cov txhuas extruded tawm ntawm qhov tuag, nws yog txias siv cua los yog dej kom khov nws cov duab tshiab.
5. Stretching thiab txiav: Lub extruded profile yog ncab kom ncaj nws thiab txo cov kev ntxhov siab sab hauv. Nws yog ces txiav mus rau qhov xav tau ntev.
6. Kev kho cua sov thiab ua kom tiav: Nyob ntawm daim ntawv thov, lub extrusion yuav raug kho cua sov los txhim kho nws cov khoom. Ntau yam txheej txheem tiav xws li anodizing lossis pleev xim kuj tseem siv tau.
Cov duab no qhia txog ntau yam aluminium extrusion, qhia txog ntau yam profiles uas tuaj yeem ua tiav los ntawm cov txheej txheem no.
Tsim rau Aluminium Extrusion
Tsim kom muaj txiaj ntsig Aluminium Extrusion Design Guide yuav tsum xav txog ntau yam:
1. Phab ntsa Thickness: Kev tuav cov phab ntsa tuab tuab pab ua kom cov khoom txaus txawm tias thaum extrusion.
2. Symmetry: Symmetrical designs feem ntau extrude yooj yim dua thiab tsis tu ncua.
3. Corner Radii: suav nrog kaum radii txo qhov kev ntxhov siab thiab txhim kho cov khoom ntws.
4. Tolerances: Kev nkag siab txog qhov ua tau zoo ntawm kev ua tau zoo pab tsim cov khoom uas tuaj yeem tsim tau zoo ib yam.
5. Kev xaiv Alloy: Cov khoom siv txhuas Extrusion sib txawv muaj cov khoom sib txawv, thiab kev xaiv cov hlau zoo yog qhov tseem ceeb rau daim ntawv thov.
Aluminium extrusion yog ntau yam thiab muaj txiaj ntsig kev tsim khoom uas txuas ntxiv mus nrhiav cov ntawv thov tshiab thoob plaws ntau yam kev lag luam. Nws lub peev xwm los tsim cov txheej txheem nyuaj nrog cov khoom siv zoo heev ua rau nws muaj txiaj ntsig zoo hauv kev tsim khoom niaj hnub. Raws li kev siv thev naus laus zis thiab cov tswv yim tshiab tau tshwm sim, cov ntawv thov muaj peev xwm rau aluminium extrusion tsuas yog txuas ntxiv mus ntxiv, ua kom nws qhov chaw yog qhov tseem ceeb hauv ntiaj teb ntawm cov khoom siv thiab kev tsim khoom.
