Taw qhia
Aluminium alloy profiles yog dav siv nyob rau hauv ntau yam lag luam vim lawv cov khoom zoo heev xws li lub teeb yuag, siab zog, thiab corrosion kuj. Txawm li cas los xij, thaum lub sij hawm tsim khoom, qhov teeb meem zoo ntawm aluminium profiles, xws li khawb, kab dub, kab ci, roughness, thiab tawg, qee zaus tshwm sim. Cov teeb meem no tsis tsuas yog cuam tshuam rau qhov zoo nkauj ntawm cov khoom tab sis kuj tseem tuaj yeem ua rau lawv qhov kev ua tau zoo. Yog li ntawd, nws yog ib qho tseem ceeb heev los soj ntsuam qhov ua rau ntawm cov teeb meem no thiab nrhiav kev daws teeb meem zoo los txhim kho cov khoom zoo thiab ua tau raws li cov neeg xav tau.
Lub ntsiab hom thiab ua rau ntawm qhov teeb meem zoo nyob rau hauv Aluminium Profiles
2.1 Scratch Issues
Scratching yog ib qho ntawm cov teeb meem zoo tshaj plaws nyob rau hauv aluminium profiles, nrog rau kev sib txawv thiab ntau yam. Tom qab kev kho pwm, yog tias cov welded steel tuav thiab ntws blocking blocks siab tshaj qhov chaw ua hauj lwm ntawm pwm, khawb tau yooj yim tsim thaum lub sij hawm extrusion. Yuav kom daws tau qhov teeb meem no, cov hlau tuav thiab cov khoom thaiv cov dej ntws tuaj yeem sib tsoo mus rau ib qho kev ncua deb ntawm thaj chaw ua haujlwm thiab raug nplua raws li qhov khiav ceev.
Tsis tas li ntawd, kev sib cuam tshuam kev khawb thaum lub sijhawm tsim khoom tuaj yeem cuam tshuam nrog cov khoom siv xws li aluminium billet, hnav ntawm cov ntaub qhwv extrusion thiab extrusion cylinders, thiab misalignment ntawm qhov chaw extrusion. Txhawm rau daws cov teeb meem no, kev tshuaj xyuas nruj ntawm aluminium billet muaj pes tsawg leeg yog qhov tsim nyog, hloov lub sijhawm ntawm cov ntaub qhwv extrusion thiab lub tog raj kheej, thiab kev hloov kho ntawm qhov chaw extrusion kom ntseeg tau tias muaj kev ntxhov siab zoo sib xws.
2.2 Kab Dub thiab Teeb Kab Teeb
Cov kab dub thiab cov kab ci ntsa iab kuj tseem cuam tshuam rau qhov zoo ntawm aluminium profiles. Cov teeb meem no feem ntau tshwm sim los ntawm qhov tsis txaus pwm polishing los yog tsis sib xws extrusion kub los ntawm cov pwm tsis sib xws. Tshwj xeeb, yog cov plua plav thiab roj paug hauv lub vuam chamber tsis huv huv thaum lub sij hawm pwm polishing, los yog cov txheej txheem polishing tsis raug (xws li longitudinal polishing), cov teeb meem no yuav tshwm sim. Tsis tas li ntawd, cov pwm tsis sib xws tuaj yeem ua rau cov vuam tsis zoo hauv lub taub hau thiab tus Tsov tus tw, ua rau cov kab dub. Txhawm rau daws cov teeb meem no, nws yog ib qho tsim nyog yuav tsum tau ntxiv dag zog rau kev cob qhia cov neeg ua haujlwm polishing kom paub meej cov txheej txheem polishing txheej txheem. Ib txhij, optimizing pwm tsim thiab txhim kho kev faib tawm tuaj yeem txo qhov tshwm sim ntawm qhov kub tsis sib xws.
2.3 Qhov teeb meem Roughness
Roughness nyob rau hauv txhuas profiles yuav categorized ua ob hom: plaub hau roughness thiab nto roughness. Cov plaub hau roughness feem ntau tshwm sim los ntawm kev ceev extrusion ntau dhau thiab kub tawm, ua rau nto streaking. Nto roughness feem ntau yog vim tsis txaus polishing ntawm pwm qhov chaw ua haujlwm. Txhawm rau daws cov teeb meem no, kev ntsuas xws li kho qhov ceev ntawm extrusion, txo qhov kub thiab txias, thiab ua kom cov txheej txheem ntau lawm rau cov cua txias tuaj yeem siv los txo cov plaub hau roughness. Tsis tas li ntawd, txhim kho kev tshuaj xyuas tom qab polishing ntawm pwm kom ntseeg tau tias polishing zoo yog qhov tseem ceeb. Tsis tas li ntawd, tswj pwm cua sov lub sij hawm yog tsim nyog kom tsis txhob nto roughness tshwm sim los ntawm cua kub ntau dhau.
2.4 Qhov teeb meem tawg
Cov kab nrib pleb yog ib qho ntawm cov teeb meem loj heev hauv cov txhuas profile, feem ntau yog vim muaj kev kub ntxhov ntau dhau thiab kub kub. Thaum lub sij hawm kub thiab high-ceev extrusion, qhov kub thiab txias qhov sib txawv ntawm sab hauv thiab sab nrauv ntawm cov profiles tuaj yeem ua rau muaj kev ntxhov siab thermal, uas ua rau tawg. Yuav kom daws tau qhov teeb meem no, nws yog ib qho tsim nyog yuav tsum tau txo qis extrusion ceev, tswj billet kub nyob rau hauv ib tug tsim nyog ntau yam (piv txwv li, 510-530 degree), thiab txais yuav ntau yam billets rau txias ntau lawm los txo cov tawv nqaij kub ntawm lub billets, yog li ntawd. minimizing high-temperature overheating.
Txhim kho cov tswv yim thiab cov kev cia siab yav tom ntej
Raws li kev soj ntsuam ntawm cov teeb meem zoo ntawm qhov chaw thiab lawv cov laj thawj hauv aluminium profiles, cov tswv yim txhim kho hauv qab no tau npaj tseg: Ua ntej, ntxiv dag zog rau cov khoom siv raw zoo tswj kom ntseeg tau tias 合格 aluminium billet muaj pes tsawg leeg; thib ob, optimize pwm tsim thiab polishing txheej txheem los txhim kho pwm precision thiab polishing zoo; thib peb, ua kom zoo dua qhov chaw ntawm cov txheej txheem extrusion tsis thiab tsim nyog tswj cov cim tseem ceeb xws li extrusion ceev thiab kub; thib plaub, txhim khu kev soj ntsuam thiab tshuaj xyuas thaum lub sij hawm tsim khoom kom sai txheeb xyuas thiab daws cov teeb meem tshwm sim. Nrog kev txhim kho thev naus laus zis tsis tu ncua thiab cov txheej txheem kev tsim kho tshiab, kev tswj hwm ntawm aluminium profile nto zoo yuav ua tau zoo dua thiab muaj txiaj ntsig. Los ntawm kev tshawb fawb thev naus laus zis tsis tu ncua thiab kev txhim kho cov txheej txheem, peb muaj laj thawj ntseeg tias qhov zoo ntawm aluminium profiles yuav raug txhim kho ntxiv, ua kom tau raws li kev lag luam xav tau thiab cov neeg siv khoom xav tau.
