Extrusion inotsanangurwa semaitiro ekuumba zvinhu, senge aruminiyamu, nekumanikidza kuti iyerere nepaburi rakaumbwa mudhiya.Zvinhu zvakawedzerwa zvinobuda sechidimbu chakarebeswa chine chimiro chakafanana nekuvhurwa kwefa.
Chinhu chinonyanya kukosha chekuyeuka mu extrusion process ndeye tembiricha.Tembiricha inonyanya kukosha nekuti inopa aluminiyamu yainoda maitiro akadai sekuoma uye kupera.
Matanho mualuminium extrusion process
1.Mabhiridha anofanira kudziyisa kusvika pa800-925° F.
2.After billet inosvika pakupisa kwaidiwa, inotamirwa kune loader apo firimu yakaonda ye smut kana lubricant inowedzerwa kune billet uye kugondohwe.Iyo smut inoshanda sechinhu chinoparadzanisa (lubricant) chinochengetedza zvikamu zviviri kuti zvisabatana.
3.Billet inotamirwa kumubhedha.
4.Gondohwe rinoshandisa kumanikidza kune dummy block iyo, iyo, inosundira billet kusvikira yave mukati memudziyo.
5.Under pressure iyo billet inopwanyika pamusoro pekufa, ichiva pfupi uye yakafara kusvikira yasangana zvizere nemadziro emudziyo.Nepo aruminiyamu ichisundirwa nemufa, mvura yenitrogen inoyerera ichitenderedza zvimwe zvikamu zvefa kuti itonhodze.Izvi zvinowedzera hupenyu hwefa uye zvinogadzira inert mhepo inochengetedza maokisidhi kubva pakuumbwa pachimiro chiri kuburitswa.Mune zvimwe zviitiko, gasi renitrogen rinoshandiswa panzvimbo pemvura ine nitrogen.Nitrogen gasi haitonhodze kufa asi inoita kuti pave nemhepo inert.6.Nekuda kwekumanikidzika kwakawedzerwa kune billet, simbi yakapfava asi yakasimba inotanga kusvina nepaburi rekufa.
7.Sezvo extrusion ichibuda mukudhinda, tembiricha inotorwa neChokwadi Temperature Technology (3T) chiridzwa chakaiswa pachitsikiro platen.Iyo 3T inorekodha yekubuda tembiricha yealuminium extrusion.Chinangwa chikuru chekuziva tembiricha ndeyekuchengetedza yakanyanya kumhanya yekutsikirira.Icho chinangwa chekubuda tembiricha yeextrusion chinoenderana nealloy.Semuyenzaniso, tembiricha yekubuda kweiyo alloys 6063, 6463, 6063A, uye 6101 ndeye 930 ° F (zvishoma).Iyo inonangwa yekubuda tembiricha yealloys 6005A, uye 6061 i950 ° F (zvishoma).
8.Extrusions inodzingwa kunze kwekufa kune tafura yekutungamirira uye inodhonza, iyo inotungamirira simbi pasi petafura yekumhanya panguva yekuwedzera.Ichiri kudhonzwa, iyo extrusion inotonhodzwa nenhevedzano yevateveri pamwe nehurefu hwese hwekumhanya-kunze uye kutonhora tafura.(Cherechedza: Alloy 6061 imvura yakadzimwa pamwe nemhepo yakadzimwa.)
9.Kwete yese yebillet inogona kushandiswa.Iyo yasara (butt) ine okisidhi kubva paganda rebillet.Iyo butt inogerwa uye inoraswa apo imwe billet inotakurwa uye yakasungirirwa kune yakambotakurwa billet uye extrusion process inoenderera mberi.Apo extrusion inosvika pakureba kwaidiwa, extrusion inotemwa neprofile saw kana shear.
10.Metal inotamiswa (kuburikidza nebhanhire kana kufamba matanda maitiro) kubva patafura yekumhanya kusvika kune inotonhorera.
11.Mushure mokunge aruminiyamu yatonhora uye inofamba pamwe chete netafura inotonhorera, inobva yaendeswa kune yakatambanudzwa.Kutambanudza kunotwasanudza maextrusions uye kunoita 'kuomesa basa' (molecular re-alignment iyo inopa aluminium kuwedzera kuoma uye kusimba kwesimba).
12.Nhanho inotevera iri sawing.Mushure mokunge maextrusions atambanudzwa anotamirwa kune tafura yesaha uye akachekwa kune hurefu chaihwo.Iko kushivirira kwekucheka pamasaha ndeye 1/8 inch kana kupfuura, zvichienderana nehurefu hwesaha.
Mushure mekunge zvikamu zvachekwa, zvinotakurwa pamudziyo wekutakura uye zvinoendeswa mumavheni ezera.Kupisa kupisa kana kuchembera kunoomesa simbi nekumhanyisa kuchembera munzvimbo inodzorwa tembiricha kwenguva yakatarwa.
