1. Txoj cai ntawm aluminium extrusion
Extrusion yog ib txoj kev ua extruding uas imposes sab nraud quab yuam ntawm cov hlau billet nyob rau hauv lub thawv (extrusion cylinder) thiab ua rau nws ntws tawm ntawm ib tug tshwj xeeb tuag qhov kom tau raws li qhov xav tau seem seem thiab loj.
2. Cov khoom ntawm aluminium extruder
Lub extruder yog tsim los ntawm thav duab, pem hauv ntej kem ncej, expansion kem, extrusion cylinder, hydraulic system nyob rau hauv hluav taws xob tswj, thiab kuj yog txawm peem rau nrog pwm puag, thimble, scale phaj, swb phaj thiab hais txog.
3. Kev faib tawm ntawm txhuas extrusion txoj kev
Raws li hom hlau nyob rau hauv lub extrusion cylinder: Kev taw qhia ntawm kev ntxhov siab thiab lub xeev strain, extrusion, lubricating xeev, extrusion kub, extrusion ceev, los yog cov hom ntawm advanced qauv, cov duab thiab tsis.ntawm qhov khoob lossis ntawm cov khoom lag luam, tuaj yeem muab faib ua qhov zoo extrusion, rov qab extrusion, (xws li lub dav hlau lim extrusion, axisymmetric deformation extrusion, dav peb-dimensional deformation extrusion) lateral extrusion, iav lubricating extrusion, Hydrostatic extrusion, nruam extrusion thiab thiaj li. ntawm.
4. Forward thermal deformation ntawm aluminium extrusion
Feem ntau ntawm cov kub deformation aluminium ntau lawm cov tuam txhab txais kev kub siab deformation extrusion txoj kev los ntawm ib qho kev tuag (flat die, cone die, shunt die) kom tau txais cov txhuas profile zoo ib yam nrog cov seem thiab cov duab.
Cov txheej txheem rau pem hauv ntej extrusion yog yooj yim, cov cuab yeej yuav tsum tsis siab, lub peev xwm hlau deformation yog siab, ntau lawm ntau, cov kev ua tau zoo ntawm txhuas yog tswj tau, cov khoom yooj yim yog loj, thiab cov pwm yog yooj yim los tswj thiab kho.
Qhov tsis xws luag yog nrog cov kev sib txhuam ntawm lub hauv paus aluminium extrusion raj, lub zog noj yog siab, kev sib txhuam lub tog raj kheej yog ib qho yooj yim los ua kom kub kub, thiab ua rau kom cov profiles tsis ruaj khov, txo cov efficiency ntawm cov khoom tiav, txwv cov txhuas thiab aluminium alloy extrusion ceev, ceev. hnav thiab kev pabcuam lub neej ntawm extrusion tuag, cov khoom tsis sib xws.
5. Hom kub deformation aluminium alloy, kev ua tau zoo thiab kev siv
Cov hom kub deformation aluminium alloy tau muab faib ua 8 pawg raws li kev ua tau zoo thiab kev siv, lawv cov kev ua tau zoo thiab kev siv sib txawv:
1) Ntshiab txhuas (L series) sib haum rau lub thoob ntiaj teb hom 1000 series ntshiab txhuas.
Muaj cov ntshiab aluminium, zoo heev machinability, corrosion kuj, nrog rau kev kho deg thiab hluav taws xob conductivity, tab sis tsis tshua muaj zog, siv nyob rau hauv tsev cov khoom, hluav taws xob khoom, tshuaj thiab khoom noj ntim, kis tau tus mob thiab faib cov ntaub ntawv, thiab lwm yam.
2) Duralumin (Ly) sib raug rau thoob ntiaj teb hom 2000 Al-Cu (Aluminium-tooj liab) alloy.
Siv rau hauv cov khoom loj, kev txhawb nqa, siab Cu cov ntsiab lus, tsis zoo corrosion kuj.
3) Rust-proof aluminium (LF) sib haum rau lub thoob ntiaj teb hom 3000 Al-Mn (aluminium manganese) alloy.
Kev kho cua sov tsis muaj zog, machinability, corrosion kuj thiab ntshiab txhuas, lub zog tau raug txhim kho, zoo vuam kev ua tau zoo, dav siv nyob rau hauv niaj hnub tsim nyog, tsev cov ntaub ntawv, pab kiag li lawm thiab lwm yam.
4) Tshwj xeeb Aluminium (LT) sib haum rau thoob ntiaj teb hom 4000 Al-Si alloy.
Feem ntau cov khoom siv vuam, qis melting point (575-630 degrees), zoo fluidity.
5) Anti-xeb txhuas (LF) sib haum rau lub thoob ntiaj teb hom 5000Al-Mg (aluminium thiab magnesium) alloy.
Kev kho cua sov tsis muaj zog, tiv thaiv corrosion, weldability, zoo heev nto gloss, los ntawm kev tswj ntawm Mg cov ntsiab lus, tuaj yeem tau txais ntau theem ntawm alloy.Qib qis rau cov khoom siv kho kom zoo nkauj, cov khoom siv siab heev;Nruab nrab qib rau nkoj, tsheb, khoom siv hauv tsev;Qib siab siv rau vuam Cheebtsam hauv tshuaj nroj tsuag ntawm nkoj thiab tsheb.
6) 6000Al-Mg-Si alloy.
Mg2Si nag lossis daus hardening kev kho cua sov tuaj yeem ntxiv dag zog rau cov hlau, zoo corrosion kuj, nruab nrab lub zog, thermal ua haujlwm zoo, yog li nws yog dav siv los ua cov khoom siv extrusion, zoo formability, siab hardness tau los ntawm quenching.Nws yog dav siv nyob rau hauv lub tsev profiles thiab yog cov khoom siv tseem ceeb hauv kev lag luam.
7) Superhard aluminium (LC) sib raug rau lub thoob ntiaj teb hom 7000Al-Zn-Mg-Cu (Al-Zn-Mg-Cu) high-strength aluminium alloy thiab Al-Zn-Mg alloy siv rau vuam cov khoom, uas muaj lub zog siab, zoo heev vuam thiab quenching kev ua tau zoo, tab sis tsis muaj kev ntxhov siab corrosion & tawg tsis kam, uas yuav tsum tau txhim kho los ntawm kev kho cua sov tsim nyog.Lub qub yog tsuas yog siv rau cov dav hlau thiab cov khoom ua si, thaum lub sij hawm tom kawg yog tsuas yog siv rau vuam cov ntaub ntawv ntawm railway tsheb.
8) 8000 (Al-Li) Aluminium-lithium alloy.
Cov yam ntxwv loj tshaj plaws yog qhov ceev yog 8% -9% qis dua 7000-series, siab rigidity, siab zog, lub teeb yuag, series yog nyob rau hauv txoj kev loj hlob (lub peev xwm los tiv thaiv kev lwj ntawm txhuas alloy hlau nyob rau hauv complex tej yam kev mob tsis tau kiag li kov yeej. ), feem ntau yog siv dav hlau, cuaj luaj, cav thiab lwm yam kev siv tub rog.
