Cov burrs loj uas ua los ntawm extrusion tuag feem ntau yog tshwm sim los ntawm qhov tsis sib xws tuag nto ua rau tsis tiav shearing, nrog txhuas maj mam lo rau sab nraud. Cov hauv qab no yog ob peb yam ua tau ntawm cov burrs loj hauv extrusion tuag:
1. Tsis sib luag lossis puas qhov kawg ntawm qhov extrusion tuag ua rau qhov khoob ntawm qhov chaw xauv, ua rau txhuas ntws tawm. Txhua qhov tsis xws luag hauv qhov tuag yuav tsum tau welded tam sim ntawd, thiab qhov tuag saum npoo yuav tsum tau milled tiaj tus.
2. Yog hais tias lub voj voog sab nraud ntawm cov khoom noj khoom haus loj dhau lawm (qhov kev ncua deb yog luv dhau), qhov chaw xauv ntawm lub thoob tuag yog me me. Qhov kev ncua deb ib txwm nyob nruab nrab ntawm lub voj voog sab nraud ntawm cov khoom noj khoom haus thiab lub thoob phab ntsa yuav tsum tawm 10 hli ntawm ib sab, nrog qhov tsawg kawg nkaus txwv ntawm 5 hli. Rau kev tuag nrog qhov sib piv siab extrusion, tsuas yog ua kom loj ntawm chav faib khoom kom txo tau siab tsis pom zoo. Thaum tsim nrog xws li extrusion tuag, nws yog ib qho tseem ceeb kom ua raws li cov sab saum toj, hauv qab, sab laug, thiab sab xis chaw kom tsis txhob muaj qhov sib txawv ntawm qhov tuag nyob deb.
3. Yog hais tias lub extrusion tuag tsis muaj milled dej channel thiab qhov tuag kaw qhov chaw loj heev, lub siab ntawm ib chav tsev cheeb tsam yuav tsawg dhau - tsawg dua qhov hluav taws xob siab. Aluminium yuav lo thiab ua rau tsis tiav shearing, uas ua rau qhov tsis sib xws ntawm qhov tuag. Cov kaus mom loj zoo li no nyuaj ua kom huv. Ua tib zoo saib xyuas kom zoo roj lub thoob qhov chaw kom tiv thaiv tau txhuas los ntawm kev nplaum. Aluminium ntawm qhov tuag nto tuaj yeem raug txiav tawm ntau zaus; roj tuaj yeem siv rau lub thoob siab cov cim ntawm qhov tuag saum npoo los tiv thaiv aluminium los ntawm kev nplaum thiab pab txhawb kev shearing. Qee lub sij hawm me me burrs tau txais raws li qhov ua tau zoo.
4. Yog hais tias lub extrusion tuag rooj vag loj me dua qhov chaw ua hauj lwm nto ntawm lub billet, qhov chaw kaw ntawm lub billet tuag yuav me dua, uas tuaj yeem yooj yim puas qhov chaw ua hauj lwm ntawm lub billet. Them mloog mus rau qhov sib tw ntawm lub rooj vag tuag txoj kab uas hla thiab qhov loj billet ua hauj lwm nto txoj kab uas hla thaum hloov lub tshuab me me tuag rau lub tshuab loj.
5. Yog tias qhov extrusion tuag thickness tsis txaus, qhov kev ntxhov siab ntawm lub tog raj kheej extrusion yuav ua rau lub tes tsho tuag. Lub thickness ntawm cov tuag thiab lub tes tsho tuag yuav tsum ua raws li 'peb rau pem hauv ntej, ib qho rov qab' txoj cai, lub ntsiab lus ntawm qhov tuag ntws ncaj qha saum npoo yuav tsum protrude 1 hli dhau ntawm lub tes tsho tuag . ------ Lub tes tsho tuag yuav tsum tsis txhob ncaj qha rau lub zog extrusion; Txwv tsis pub, lub tes tsho tuag yog qhov ua rau puas thiab deformation.
6. Yog hais tias qhov haum clearance nruab nrab ntawm lub tes tsho tuag thiab tuag yog loj heev, txhuas sticks nyob rau hauv lub clearance, ua rau tsis tiav shearing thiab tsis sib xws qhov chaw tuag. Qhov xwm txheej no feem ntau pom thaum tuag raug hloov kho los ntawm cov tshuab me me.
7. Yog tias qhov sib piv extrusion siab dhau lawm, ua rau lub qhov hluav taws xob tiv thaiv kom dhau lub zog extrusion, lub qhov rooj xauv yuav tsis sib npaug, tso cai rau txhuas los ntawm qhov chaw xauv. Qhov no feem ntau ua rau muaj qhov tshwm sim ntawm kev thaiv. Koj tuaj yeem tsim kom muaj qhov kub thiab txias, qhov kub thiab txias ntawm lub thoob. Yog tias tsim nyog, ua ntej- sov lub tes tsho tuag lossis txawm tias shims ua ntej tsim khoom. Tsis tas li ntawd, ua kom luv luv me ntsis ntawm qhov ntev ntawm qhov ntev kom txo qhov loj me. Rau cov ntawv txhuas txhuas uas luv luv, stamping ntau lawm yog pom zoo es tsis yog tsuas yog nce qhov kub ntawm billet. Kub billet kub kuj tuaj yeem ua rau lub taub hau tsis xws luag thiab txwv kev txhim kho ceev.
