Nrog rau kev tiv thaiv ntxiv ntawm kev tiv thaiv ib puag ncig, kev txhim kho thiab tawm tsam ntawm lub zog tshiab thoob ntiaj teb tau tshaj tawm cov tsheb muaj zog. Nyob rau tib lub sijhawm, cov kev cai rau kev sib xws media kev txhim kho ntawm cov ntaub ntawv hauv tsheb, thiab lawv cov khoom sib xws, qhov loj me yog ua kom siab dua thiab siab dua. Noj lub tsheb khiav ntawm lub tsheb ntawm 1.6t ua piv txwv, cov khoom siv aluminoy aluminium yog li 450kg, suav nyiaj rau txog 30%. Cov txheej txheem sib xws uas tshwm sim hauv cov txheej txheem sib txawv, tshwj xeeb yog qhov teeb meem sib xyaw ntawm cov khoom siv sab hauv thiab sab nraud ntawm lawv txoj kev thov kev thov.
Rau extruded profiles, tsim qauv thiab tsim cov kev sib sau ua ke yog ntawm qhov tseem ceeb tshaj plaws, yog li kev tshawb nrhiav thiab kev tsim kho ntawm cov profative. Kev tawm tswv yim thiab tsim nyog tuag cov kev daws teeb meem tuaj yeem txhim kho tus nqi tsim nyog thiab cov khoom tsim qauv zoo ntawm cov khoom siv ua lag luam.
1 cov qauv khoom lag luam
(1) Cov ntaub ntawv, kev kho deg thiab kev tiv thaiv corrosion thiab cov khoom siv rau txhuas cov kev xav tau rau Anyodic oxidation saum npoo Kev kho mob ".
(2) Kev kho deg: anodic oxidation, lub npoo yuav tsum tsis txhob muaj nplej coarse.
(3) Qhov chaw ntawm cov ntu tsis pub muaj qhov tsis xws luag xws li cov kab nrib pleb thiab pob. Cov seem tsis pub kom muaj paug tom qab oxidation.
(4) Cov tshuaj txwv ntawm cov khoom tau raws li qhov yuav tsum tau ua L / JL J160001-2017 "Yuav tsum tau txwv thiab txwv cov khoom thiab cov khoom siv".
(5) Kev ua kom zoo dua ib yam: tensile zog ≥ 210 MPa, tawm lub zog ≥ 180 mpa, elongation tom qab pob txha lov pob txha a50 ≥ 8%.
(6) qhov xav tau rau txhuas alloy muaj pes tsawg leeg rau cov khoom siv hluav taws xob tshiab tau qhia hauv Table 1.
2 Txhim Kho thiab Tshaj Tawm Kev Ntsuam Xyuas ntawm Extrusion Tuag Qauv Loj-teev Hwj chim txiav
(1) Kev daws teeb meem 1: Uas yog, txhawm rau txhim kho pem hauv ntej extrusion tuag lub tswv yim, raws li muaj nyob hauv daim duab, tus nruab nrab tav txoj hauj lwm yog Cov txheej txheem, cov dej ntws sab saud yog 20 ° ntawm ib sab, thiab qhov dej siab qhov siab H15 mm yog siv los muab molten aluminium rau rib ib feem. Raimlingual rab riam yog pauv ntawm txoj cai kaum, thiab molten aluminium tseem nyob ntawm lub ces kaum, uas yog qhov yooj yim los tsim cov cheeb tsam tuag nrog txhuas slag. Tom qab kev tsim khoom, nws yog kev txheeb xyuas los ntawm oxidation uas cov nplaim yog qhov tsis tshua muaj txiaj ntsig heev rau kev sib cav sib ceg.
Cov kev ua tiav hauv qab no tau ua rau cov tsoos pwm tsim khoom lag luam:
a. Raws li cov pwm no, peb tau sim ua kom cov txhuas ua kom cov tav los ntawm kev pub mis.
b. Ntawm lub hauv paus ntawm tus thawj tob, rawv zob hlua khoob tob yog qhov tob tob, uas yog, 5 hli ntxiv rau thawj 15 hli;
c. Qhov dav ntawm cov hniav npog khoob yog widened los ntawm 2 hli raws li tus thawj 14mm. Cov duab tiag tiag tom qab kev ua tau zoo yog qhia hauv daim duab 3.
Cov txiaj ntsig kev tshawb fawb pom tau tias tom qab peb sab saum toj no txhim kho tseem muaj nyob rau hauv cov profiles tom qab oxidation kev kho mob thiab tsis tau daws teeb meem. Qhov no qhia tau hais tias kev txhim kho kev ua ntej yuav tsis tuaj yeem ua tiav cov kev tsim khoom ntawm cov ntaub ntawv aluminium alloy rau EVS.
(2) Cov phiaj xwm tshiab 2 tau npaj siab raws li kev ua kom ua ntej. Cov pwm tsim qauv tshiab ntawm cov phiaj xwm tshiab 2 tau pom hauv daim duab 4. Raws li kev ua lag luam "cov qauv" qhib qhov "tsim qauv. Tus tav txoj hauj lwm ua lub luag haujlwm rau kev cuam tshuam ncaj qha thiab txo kev sib txhuam kev sib txhuam; Cov khoom noj khoom noj yog tsim los ua "lub lauj kaub npog-puab" thiab lub hom phiaj yog txhawm rau txhawm rau ua kev sib txhuam tsis kam, txhim kho kev sib txhuam, thiab txo cov kev tiv thaiv kev tiv thaiv; Tus choj yog Sunken ntau li ntau tau los tiv thaiv cov teeb meem ntawm cov coarse nplej rau hauv qab ntawm tus choj, thiab qhov dav ntawm lub ntsej muag khoob hauv qab yog ≤3mm; cov kauj ruam sib txawv ntawm kev ua haujlwm ntawm txoj siv ua haujlwm thiab cov neeg nyob qis zog ua haujlwm yog ≤1.0 hli; Qhov khoob riam nyob rau hauv lub sab sauv tuag tus nplaig yog du thiab me ntsis hloov chaw, tsis tas tawm ntawm qhov kev sib tw ntws, thiab qhov kev sib tw qhov yog punched raws li ua tau; Txoj siv sia ntawm ob lub taub hau nyob hauv nruab nrab sab hauv yog luv li sai tau, feem ntau noj tus nqi ntawm 1.5 txog 2 zaug ntawm phab ntsa tuab; Qhov dej ntws tawm muaj kev hloov pauv kom tau raws li qhov kev xav tau ntawm cov kab noj hniav zoo li qub, thiab tawm ib rab riam tsis muaj zog nyob hauv txhua qhov chaw sab sauv tsis pub tshaj 2 txog 2.5mm ). Qhov sib piv ntawm cov extrusion tuag qauv ua ntej thiab tom qab kev txhim kho tau pom hauv daim duab 5.
(3) Ua tib zoo mloog rau kev txhim kho ntawm kev ua cov ntsiab lus. Tus choj txoj haujlwm yog polished thiab txuas nrog txoj hlua khi thiab qis dua yog kho kom zoo dua los txo qhov tsis ncaj ncees. Nws tuaj yeem ua kom zoo rau cov teeb meem coarsearsearse thiab kev ceev nrawm rau lwm qhov, thiab kev pom zoo thiab kev pom zoo ntawm cov npoo ntawm aluminium profile. Qhov kev sib piv ua ntej thiab tom qab cov pwm ua kom tau cov dej ntws tawm yog muaj nyob hauv daim duab 6.
3 Txheej txheem Extrusion
Rau 6063-T6 Txhuas Alloy rau EVS, qhov Extrusion Recio ntawm kev sib cais tau suav nrog 20-80, thiab cov khoom siv txhuas cov khoom siv nyob rau xyoo 1800 zaug yog 23, uas tau raws cov kev yuav tsum tau ua ntawm lub tshuab. Qhov txheej txheem Extrusion yog qhia hauv Table 2.
Rooj 2 Exustrusion Txheej Txheem ntawm Aluminium Profiles rau Mounting Beams ntawm Cov Roj Teeb Tshiab
Them sai sai rau cov ntsiab lus hauv qab no thaum extruding:
(1) Nws raug txwv tsis pub ua kom sov cov pwm nyob hauv tib lub cub tawg, txwv tsis pub cov pwm kub yuav tshwm sim yooj yim.
(2) Yog tias qhov txawv txav ntawm lub sijhawm thaum lub sijhawm sib txawv, lub sijhawm kaw yuav tsum tsis pub tshaj 3 feeb, txwv tsis pub tus pwm yuav tsum raug tshem tawm.
(3) Nws raug txwv kom rov qab mus rau qhov cub cua kom sov thiab tom qab ntawd extrude ncaj qha tom qab hais tias yuav tsum tau hais ncaj qha tom qab hais tias yuav tsum tau ncaj qha tom qab kev hais plaub.
4. Pwm kho kev ntsuas thiab lawv cov txiaj ntsig
Tom qab kaum ob ntawm pwm kho thiab sim cov kev txhim kho pwm, cov hauv qab no tsim kho cov phiaj xwm kho tau zoo li no.
(1) Ua thawj txoj kev kho thiab kev hloov kho rau tus thawj pwm:
① Sim tog tus choj ntau li ntau tau, thiab qhov dav ntawm tus choj hauv qab yuav tsum yog ≤3mm;
Ruam kauj ruam sib txawv ntawm txoj siv sia ntawm lub taub hau thiab txoj siv sia ntawm cov pwm qis dua yuav tsum yog ≤1.0 hli;
③ Tsis txhob tso cov kev thaiv;
④ Kev siv tes ua haujlwm nruab nrab ntawm ob tus txiv neej lub taub hau yuav tsum yog luv li sai tau, thiab kev hloov pauv ntawm lub qhov muag ntws tawm yuav tsum yog tus, loj thiab du li sai tau;
Kev siv tes ua haujlwm ntawm cov pwm qis dua yuav tsum yog luv li sai tau;
Tsis yog thaj chaw tuag yuav tsum tau sab laug ntawm txhua qhov chaw (nraub qaum tas li yuav tsum tsis pub tshaj 2mm);
Kho cov pwm sab saud nrog cov ntxhib cov kab noj hniav, txo qhov txoj hlua khi ua haujlwm ntawm cov neeg nyiam kev ua haujlwm, lossis tsis muaj txoj siv kev khiav tawm ntawm cov pwm.
(2) raws li cov pwm ntxiv thiab txhim kho ntawm cov pwm saum toj no, cov pwm hauv qab no tau ua:
① Tshem tawm cov chaw tuag ntawm ob tus txiv neej lub taub hau;
② Hlaws tawm ntawm cov kev thaiv kev txaus;
Txo cov qhov sib txawv qhov txawv ntawm lub taub hau thiab qhov chaw ua haujlwm qis dua;
Luv luv luv qhov qis dua qhov chaw ua haujlwm.
(3) Tom qab cov pwm raug kho thiab txhim kho, cov khoom ua tau zoo tshaj plaws, nrog cov teeb meem zoo nkauj, vuam thiab lwm yam tsis xws luag nyob rau saum npoo ntawm Aluminium Profiles rau EVS.
(4) cov extrusion ntim nce los ntawm tus thawj 5 t / d rau 15 T / D, muaj kev txhim kho ntau dua.
5 lub ntsiab lus
Los ntawm kev ua kom zoo dua thiab txhim kho cov thawj coj pwm, ib qho teeb meem loj ntsig txog cov hmoov nplej rau saum npoo thiab vuam ntawm aluminium profiles rau EVS tau daws kom haum.
(1) Cov tsis muaj zog txuas ntawm tus thawj pwm, nruab nrab tav txoj hauj lwm kab, yog qhov ua tau zoo. Los ntawm tshem tawm cov chaw tuag ntawm ob lub taub hau, pluav qhov sib txawv ntawm lub taub hau thiab ua haujlwm qis dua ntawm 6063 aluminium alloy siv nyob rau hauv hom ntawm no Tsheb tsheb, xws li coarse nplej thiab vuam, tau ua tiav kev vam meej.
(2) Cov extrusion ntim nce ntxiv los ntawm 5 T / D rau 15 T / D, txhim kho ntau dua kev ua tau zoo.
(3) Cov ntaub ntawv ua tiav ntawm Extrusion Tuag Tsim thiab tsim khoom yog tus sawv cev thiab saib xyuas cov khoom siv zoo sib xws thiab yog tsim nyog txhawb nqa.
