Zuag qhia tag nrho, cov txheej txheem extrusion yog qhov tseem ceeb tshaj plaws thiab tseem ceeb tshaj plaws hauv kev ua txhuas profile, thiab tag nrho cov txheej txheem precision nyob ntawm kev tswj xyuas ntawm txhua theem tseem ceeb.
Yog vim li cas extrusion tsim lub hauv paus?
Extrusion yog tus neeg nqa khoom ncaj qha rau txhuas profile kom ua tiav cov qauv ntoo khaub lig- ntu, qhov tseeb qhov tseeb, thiab cov khoom siv tshuab yooj yim; Nws yog sib npaug rau "forming core" ntawm tag nrho cov kev khiav dej num:
Nws ncaj qha txiav txim siab cov khoom lag luam qhov tseeb thiab cov duab: Tus ntoo khaub lig-sectional duab ntawm aluminium profile yog txiav txim siab tag nrho los ntawm kev tsim qauv tuag thiab txheej txheem extrusion. Ib qho kev sib txawv ntawm extrusion ceev, kub, los yog siab yuav ua rau profile twisting, dabtsi yog khoov, thiab tshaj qhov ntev kam rau ua, ncaj qha cuam tshuam rau tom qab sib dhos thiab siv.
Nws cuam tshuam rau qhov kawg txhua yam khoom: Thaum lub sij hawm extrusion txheej txheem, dynamic tshuav nyiaj li cas ntawm kub, ceev, thiab extrusion siab yuav tsum tau matched nyob rau hauv lub sij hawm. Piv txwv li, qhov kub ntawm 6063 alloy tuav yuav tsum tau tswj ntawm 480-520 degree. Kev sib txawv ntawm qhov nrawm yuav ncaj qha ua rau cov kab nrib pleb los yog kev ua haujlwm tsis sib xws, uas yog lub hauv paus rau kev kho cua sov tom qab thiab kev kho deg.
Cov txheej txheem siab tshaj plaws: Rau qhov tsis sib xws tsis sib xws - ntu thiab loj - qhov loj me profiles, pwm tsim thiab extrusion parameter debugging yuav tsum tau ntev - cov txheej txheem tsub zuj zuj, ncaj qha txiav txim siab cov chaw tsim khoom muaj peev xwm thiab cov khoom lag luam zoo qab nthab.
Lwm qhov txuas tseem ceeb uas tsis tuaj yeem tsis quav ntsej:
Dhau li ntawm extrusion, ob qhov txuas no kuj ncaj qha txiav txim siab cov khoom zoo kawg nkaus:
Casting: Raws li qhov pib ntawm kev tsim khoom, nws txiav txim siab qhov zoo ntawm qhov profile. Yog tias degassing tsis tiav lossis qhov sib piv ntawm qhov sib txawv, nws yuav ua rau cov porosity thiab suav nrog hauv cov pas nrig aluminium, inevitably ua rau seem hauv cov extrusion tom ntej, tshwj xeeb tshaj yog rau thermally tawg aluminium profiles, qhov zoo ntawm casting ncaj qha cuam tshuam cov txiaj ntsig ntawm cov theem sib xyaw.
Kev laus kev kho mob: Qhov no yog theem kawg ntawm kev ua tiav qhov kawg lub zog thiab hardness ntawm aluminium profile. Qhov sib txawv ntawm qhov kub thiab txias tswj lub sijhawm yuav ncaj qha ua rau lub zog tsis txaus lossis dhau -aging thiab brittleness, cuam tshuam ncaj qha rau kev ua haujlwm.
