Raws li paub, nrog tnws ruaj khov,nruam thiab ceev nrooj kev loj hlob ntawm peb lub teb chaws kev lag luam thiab high technology, aluminium smelting thiab aluminium profile ua kev lag luam hauv Suav tebtau txhawb txoj kev loj hlob sai.Cov khoom siv aluminium profile tau dhau los ua neeg nyiam nyob hauv txhua qhov chaw. Tab sis li cas cov khoom siv aluminium profile los ntawm? Hnub no, cia's kawm txog kev ua ntawm txhuas profile extrusion ua ke.
Aluminium profile extrusion yog dab tsi?
Aluminium profile extrusion yog ib txoj hauv kev uas yuav muab txhuas ua qhov teeb meem los ntawm qhov tshwj xeeb tuag, thiaj li ua tau raws li qhov xav tau ntawm cov ntoo khaub lig seem hlau ntxig rau hauv lub tog raj kheej extrusion nrog ib qho nyiaj ntawm lub siab kom zoo thiab loj.
Thyogtxheej txheem extrusionoccupies ib qho kev faib ua feem ntaunyob rau hauv niaj hnub industrial ntau lawm system nrog tus nqi qis tab sis high efficiency thiab yooj yim khiav lag luam. Yog li ntawd, aluminium profile plays lub hauv paus tseem ceeb hauv kev lag luam hauv lub tebchaws.
Ua ntawm aluminium profile extrusion
Yuav ua li cas rau extruded aluminium?Aluminium profiles yuav tsum tau extruded raws li cov txheej txheem hauv qab nohauv:

Tshawb xyuashauvroj system → checkhauvcua siab system → checkhauvcov khoom siv hluav taws xob thiab hluav taws xob → koshauvdej ntws system → checkhauv tustus naj npawb ntawm aluminium rods thiab cov qauv ntawm cov pwm.
Cov ntsiab lus ntawm kev tshuaj xyuas kev npaj:
1. Checkhauv cmuaj tseebseb cov roj hluav taws xob ntawm txhua qhov extrusion ntau lawm kab yog qhov qub;
2. Checkua kom zoo zooseb qhov khoom ntawm lub tshuab cua siab yog normal, thiab sauhauvtus nqi ntws thiab siab;
3. Checkua kom zoo zooseb tag nrho cov kab thiab cov khoom siv hluav taws xob yog qhov qub thiab seb qhov hluav taws xob puas nyob hauv qhov chaw ruaj khov ntawm 380V;
4. Checkua kom zoo zooseb qhov dej txias ntawm cov dej txias tau qhib, thiab seb cov dej siab thiab cov dej ntws zoo li cas nyob rau hauv cov kev cai;
5. Tshawb xyuashauvraw cov ntaub ntawv, thiab kuajua kom zoo zooseb tus naj npawb ntawm txhuas rods yog raws li tus qauv pwm.
Cov txheej txheem ntawm extrusion
Aluminium pas nrig tiling → cua sov 12 txhuas rods ntawm ib lub sij hawm → kub txog li 480 degree tuav rau 1H → Pwm cua sov mus rau 480 degree → Pwm rau hauv lub tuag yas dhos → pub rau raw khoom lub qhov ncauj → extrusion → traction → straightening → laus → tawm ntawm Lub qhov cub → tuav 2h tom qab 200 degree → txias → tiav
Cov ntsiab lus ntawm txhua qhov txheej txheem rau extrusion:
1. Muab tsonpaj aluminium pas nrigtiaj tusntawm cov khoom txee thiab khaws ciahauvib qho kev sib txawv ntawm cov pas nrig aluminium.Nws yuav tsum tau muab sau tseg tiaslub aluminium rodua tsis taupawged, txwv tsis pub nws yuav txhim khu qhov nyuaj ntawm extruder, thiabua mob rau cov neeg ua haujlwmyog tias aluminium pas nrig poobthaum ua haujlwm.
2. Skev cailyraws li tus txheej txheemhauv, 12 txhuas rods muab tso rau hauv lub cub tawg thiab cua sov ntawm chav tsev kub. Thaum lub sij hawm cua sov mus txog 3.5h, qhov kub nce mus txog 480 degree, thiab tom qab ntawd cov khoom qub tuaj yeem nqa tawm tom qab tuav rau 1h.
3. Nyob rau tib lub sijhawm, muab cov pwm extrusion rau hauv qhov cub kom sov, kom cov pwm kub kuj nce mus txog 480 degree;
4. Tom qab cov cua sov thiab kev txuag hluav taws xob ua haujlwm ntawm txhuas pas nrig thiab pwm ua tiav, muab cov pwm tso rau hauv lub hauv paus tuag ntawm extruder thiab npaj txhij;
5. Muabtingqhov txiavtingaluminium pas nrig rau hauv cov khoom siv raw nkag ntawm lub extruder los npaj rau extrusion;
6. Nkag mus rauextrusion theem,tom qab tau tawm ntawmlub qhov hluav taws xob, extrudedprofileyuav yog rub los ntawmtshuab traction thiab teem caij ntev rau kev txiav. Ces,aluminium profileyuav yogxa mus rau lub rooj ncaj nraim rau kev ncaj, thiab thauj mus rau qhov chaw tiav cov khoom rau sizingtxiav tom qab ncaj.
7. Tom qab txiav raws li qhov xav tau,aluminium profileyuav loadednyob rau hauv cov khoom thav duabthiabthaujedmus rau qhov chaw laus rau kev laus kev kho mob. Yogcov laus kub ncav cuag 200 degreethiabtuavhauvcua sov rau 2 teev,nws yog sij hawm tosqhov cub;
Tom qab ua tiav kev laus,aluminium profile yuavraug tso tawmthiab ces nkag rau hauvcua txias theem. Cooled lawm los yog txias los ntawm cua txiasyog ok.
Yog li ntawd, covtag nrhoextrusion ua haujlwmntawm aluminium profileyog tiav nrog tsim nyog tsoszoo lipuab thiab loj.
