Cov kev cai rau kev tsim extrusion ntawm aluminium profile radiators yuav tsum pib nrog qhov zoo ntawm cov khoom siv, cov khoom siv thiab tsim pwm, txo cov extrusion quab yuam thiab txheej txheem extrusion. Hnub no, Jinlu yuav qhia koj txog cov kev cai tshwj xeeb:
Ua ntej ntawm tag nrho cov, thawj lub ntsiab lus yog qhov yuav tsum tau zoo ntawm lub ingot:
Qhov saum npoo ntawm lub ingot yuav tsum yog du, tsis muaj cov kab mob sib cais lossis cov xuab zeb nplaum. Qhov kawg ntawm lub ingot yuav tsum tiaj tus, thiab yuav tsum tsis txhob muab txiav mus rau hauv cov kauj ruam los yog txiav txoj kab nqes yuav tsum loj heev (qhov txiav txoj kab nqes yuav tsum yog 3 hli hauv). Vim yog cov kauj ruam loj heev los yog txiav txoj kab nqes, thaum tshav kub dissipation profile yog extruded nrog lub tiaj tus tuag, yog tias tsis muaj cov pas nrig qhia, lub ingot yuav ncaj qha hu rau tus tuag. Vim qhov tsis sib xws ntawm qhov kawg ntawm qhov ingot, qee qhov chaw yuav hu rau pwm ua ntej, uas yuav ua rau muaj kev ntxhov siab, uas yooj yim rau nyem cov hniav ntawm cov pwm, los yog ua rau muaj qhov sib txawv ntawm cov pwm, uas yooj yim ua rau pwm thaiv. los yog tsis zoo extrusion molding.
Tom qab ntawd lub ntsiab lus thib ob yog qhov yuav tsum tau ua rau pwm:
Vim tias cov pwm ntawm radiator profile yog ua los ntawm ntau cov hniav, nws yuav tsum tiv taus lub zog loj extrusion, thiab txhua tus hniav yuav tsum muaj lub zog siab thiab toughness. Yog tias qhov kev ua tau zoo ntawm ob qhov sib txawv heev, cov hniav uas tsis muaj zog lossis tawv tawv tuaj yeem tawg tau yooj yim. Yog li ntawd, qhov zoo ntawm cov hlau tuag yuav tsum txhim khu kev qha. Nws yog qhov zoo tshaj plaws los siv H13 steel lossis siab -cov hlau zoo uas tsim los ntawm cov chaw tsim khoom txhim khu kev qha. Kev kho cua sov ntawm pwm yog qhov tseem ceeb heev. Xav tau lub tshuab nqus tsev cua sov thiab quenching. Nws yog qhov zoo tshaj plaws los siv siab - siab ntshiab nitrogen quenching kom ntseeg tau tias kev ua tau zoo ntawm txhua qhov ntawm cov pwm tom qab quenching. Tom qab quenching, nws yuav tsum tau tempered peb zaug kom paub meej tias lub hardness ntawm pwm yog HRC48 mus rau 52. Qhov no yog ib qho tseem ceeb rau kev tiv thaiv cov pwm los ntawm tawg cov hniav.
Tom qab ntawd lub ntsiab lus thib peb yuav tsum nco ntsoov yog kom txo lub zog squeezing:
Txhawm rau tiv thaiv cov pwm los ntawm kev rhuav tshem cov hniav, lub zog extrusion yuav tsum raug txo kom ntau li ntau tau, uas cuam tshuam rau qhov ntev ntawm lub ingot, kev tiv thaiv rau deformation ntawm cov hlau, lub xeev thiab cov degree ntawm deformation ntawm lub ingot. . Yog li ntawd, cov cam khwb cia ntawm extruded cua sov{{0}}dissipating aluminium profiles yuav tsum tsis txhob ntev dhau, hais txog qhov ntev cam khwb cia pas nrig ntev (0).6 0.85 zaug). Tshwj xeeb tshaj yog thaum kuaj cov pwm thiab extruding thawj tus pas nrig casting, txhawm rau ua kom cov khoom tsim nyog ntawm cov khoom tsim nyog, nws yog qhov zoo tshaj plaws los siv cov pas nrig luv luv, uas yog, qhov ntev ntawm cov pas nrig casting ntev (0.4-0.6) ob npaug ntawm cov pas nrig casting. pwm. Rau qhov seem ntawm lub tshuab radiator profile nrog cov duab nyuaj, ntxiv rau qhov luv luv ntawm qhov ntev ntawm cov cam khwb cia, nws tseem tuaj yeem xav txog kev siv cov ntshiab txhuas luv luv casting rau thawj zaug extrusion thiab tom qab ntawd siv cov ingot extrusion ib txwm.
Thaum kawg, lub ntsiab lus thib plaub yuav tsum nco ntsoov yog txheej txheem extrusion:
Tus yuam sij rau kev tsim cov radiator profiles yog thawj qhov kev sim ntawm extrusion tuag. Yog tias muaj kev tso cai, koj tuaj yeem ua qhov simulation sim ntawm lub khoos phis tawj ua ntej kom pom tias txoj siv sia ua haujlwm ntawm cov pwm tsim tsim nyog, thiab tom qab ntawd sim cov pwm ntawm lub extruder. Thawj pwm kuaj yog ib qho tseem ceeb heev. Tus neeg teb xov tooj yuav tsum thawb lub ntsiab plunger rau pem hauv ntej, lub siab tsawg dua 8MPa thiab maj mam txav mus rau pem hauv ntej nyob rau hauv qis qis. Nws yog qhov zoo tshaj rau ib tug neeg saib ntawm lub qhov hluav taws xob pwm nrog lub teeb lub raj. Tom qab txhua lub radiator ntawm extrusion tuag yog uniformly extruded tawm ntawm lub qhov tuag, lub extrusion yuav maj mam accelerated. Thaum txuas ntxiv nyem tom qab kev sim pwm ua tiav, ua tib zoo saib xyuas qhov kev sib txhuam ceev kom ntseeg tau tias kev ua haujlwm du. Thaum tsim cov radiator profiles, xyuam xim rau cov cua kub ntawm cov pwm kom cov pwm kub yog nyob ze rau qhov kub ntawm ingot. Yog tias qhov kub sib txawv loj dhau lawm, qhov kub ntawm cov hlau yuav txo qis vim qhov qeeb extrusion ceev thaum lub sij hawm nce siab, uas yuav yooj yim ua rau pwm thaiv los yog tsis sib xws.
