Aluminium Extrusion

Extrusionyog cov txheej txheem los ntawm cov hlau ncaj ncaj tuaj yeem tsim tau.Cov ntu ntu uas tuaj yeem tsim tau txawv ntawm cov khoom puag ncig, duab plaub, rau L duab, T duab.Tube thiab ntau yam sib txawv.Extrusion yog ua los ntawm squeezing hlau nyob rau hauv ib tug kaw kab noj hniav los ntawm ib lub cuab tam, hu ua ib tug tuag siv ib tug mechanical los yog hydraulic xovxwm.

Extrusion tsim compressive thiab shear rog hauv Tshuag.Tsis muaj tensile tsim, uas ua rau siab deformation tau yam tsis muaj tearing cov hlau.Lub kab noj hniav nyob rau hauv uas cov khoom raw yog nyob rau hauv lined nrog ib tug hnav resistant khoom.Qhov no tuaj yeem tiv taus qhov siab radial loads uas yog tsim thaum cov khoom raug thawb lub tuag.

Extrusion, feem ntau txo qhov kev xav tau ntawm kev ua haujlwm thib ob, tab sis tsis yog qhov tseeb ntawm qhov tseeb lossis qhov chaw tiav raws li cov khoom siv.Nto tiav rau hlau yog 3um;(125 uin), thiab Aluminium thiab Magnesium yog 0.8 um (30 uin).Txawm li cas los xij, cov txheej txheem no tuaj yeem tsim tau ntau yam ntawm cov ntu ntu uas nyuaj los tsim cov nqi tsim nyog siv lwm txoj hauv kev.Qhov tsawg kawg nkaus thickness ntawm hlau yog li 3 hli (0.120 nyob rau hauv), whereas Aluminium thiab Magnesium yog hais txog 1 hli (0.040 nyob rau hauv).Qhov tsawg kawg nkaus hla ntu yog 250 mm2 (0.4 in2) rau cov hlau thiab tsawg dua li ntawm Aluminium thiab Magnesium.Qhov tsawg kawg nkaus kaum thiab fillet radii yog 0.4 hli (0.015 nyob rau hauv) rau Aluminium thiab Magnesium, thiab rau cov hlau, qhov tsawg kawg nkaus lub kaum sab xis yog 0.8 hli (0.030 nyob rau hauv) thiab 4 hli (0.120 nyob rau hauv) fillet radius.

Txias Extrusion:Txias extrusion yog txheej txheem ua nyob rau hauv chav tsev kub los yog siab kub me ntsis.Cov txheej txheem no tuaj yeem siv rau feem ntau cov ntaub ntawv-txoj kev tsim cov cuab yeej muaj zog txaus uas tuaj yeem tiv taus cov kev ntxhov siab tsim los ntawm extrusion.Piv txwv ntawm cov hlau uas tuaj yeem extruded yog txhuas, tin, aluminium alloys, tooj liab, titanium, molybdenum, vanadium, hlau.Piv txwv ntawm qhov chaw uas txias extruded yog collapsible raj, txhuas cov kaus poom, lub tog raj kheej, iav blanks.Qhov zoo ntawm txias extrusion yog:

• * Tsis muaj oxidation tshwm sim
• *Cov khoom siv zoo zoo vim yog qhov ua haujlwm txias txias ntev li ntev tau raws li qhov ntsuas kub tsim tau qis dua qhov kub ntawm qhov rov ua kom sov
• *Zoo nto tiav nrog kev siv cov lubricants kom raug

Kub Extrusion:Kub extrusion yog ua tiav ntawm qhov kub thiab txias, kwv yees li 50 mus rau 75% ntawm lub melting point ntawm cov hlau.Lub siab tuaj yeem nyob ntawm 35-700 MPa (5076 - 101,525 psi).Vim yog qhov kub thiab txias thiab nws cov kev puas tsuaj rau lub neej tuag nrog rau lwm yam khoom, lubrication zoo yog tsim nyog.Roj thiab graphite ua hauj lwm nyob rau hauv qis kub, whereas nyob rau hauv siab kub iav hmoov yog siv.

Yam khoom uas tsim los ntawm extrusion yog trim qhov chaw siv nyob rau hauv tsheb thiab kev tsim kho daim ntawv thov, qhov rais ncej cov tswv cuab, railings, aircraft structural qhov chaw.
