Inqubo ye-Aluminium extrusion:
I-extrusion yangempela iqale nge-extrusion cast in aluminium rod, induku ye-aluminium ekubunjweni kumele ishiswe ngaphambi kokuncibilikiswa ukuze kuyithambise, ukufudumeza okuhle kwe-aluminium ekubunjweni kwezinduku sheng ingot kufakwa emgqonyeni we-extruder ngaphakathi, bese kuqhutshwa amandla amakhulu we-hydraulic extrusion rod, i ingaphambili lenduku ye-extrusion inephedi yengcindezi, i-aluminium ingxubevange ethambile evuthayo ku-dummy block ngaphansi kwengcindezi enamandla evela kusikhunta ngokunemba ekubumbeni i-extrusion, thola umkhiqizo wokugcina.
Ibha ye-aluminium ayinalutho ngenqubo ye-extrusion. Ibha ye-aluminium ye-extrusion ingaqina noma ingabi nalutho, imvamisa i-cylindrical, futhi ubude bayo bunqunywa yizinto zokuphotha ze-extrusion.Imigoqo ye-Aluminium ivame ukwenziwa, eminye ifohliwe noma icindezelwe.Ivame ukwenziwa ngokusika imigoqo ye-aluminium alloy enokwakheka okuhle kwe-alloy.Izinduku zivamise ukufutheliselwa kuma-degree angama-450 esithandweni sokufudumeza ngaphambi kokuba zithunyelwe, nge-10% esele ema-ingots.
Ukuhlukaniswa kwezindlela ze-extrusion:
1. Ngokwesikhombisi-ndlela se-extrusion: phambili extrusion, reverse extrusion, lateral extrusion
2. Ngokuya ngezici zokusonteka: indiza ukusonteka i-extrusion i-axial symmetry deformation extrusion jikelele i-three-dimensional deformation extrusion
3. Ngokuya ngesimo sokuthambisa: akukho ukuthambisa okugcotshwayo okugcotshwayo okungcono ukugcoba okungcono
Izinzuzo zokucubungula kwe-extrusion:
1. Thuthukisa ikhono lokusonteka lensimbi
Isilinganiso se-extrusion se-aluminium emsulwa singafinyelela ku-500, isilinganiso se-extrusion sethusi elimsulwa singafinyelela ku-400, kanti isilinganiso se-extrusion sensimbi singafinyelela ku-40-50.
2. Imikhiqizo ye-extrusion inekhwalithi ephezulu ephelele
I-extrusion deformation ingathuthukisa ukwakheka kwe-microstructure kanye nemishini yokwenza izinto zensimbi, ikakhulukazi kuma-alloys athile e-aluminium anomphumela we-extrusion, ubude be-longitudinal (extrusion direction) izakhiwo zemikhiqizo ekhishiwe ngemuva kokucima nokuguga kuphakeme kakhulu kunemikhiqizo efanayo ekhishwa ezinye izindlela zokucubungula .
3. Imikhiqizo ye-Extrusion inebanga elibanzi
Ukucutshungulwa kwe-extrusion akukwazi ukukhiqiza kuphela ipayipi, induku kanye nocingo olunokuma okulula kwesigaba, kepha futhi kungakhiqiza izigaba eziqinile nezizungezile ezinokuma okuyinkimbinkimbi kakhulu kwesigaba, nezigaba zesigaba eziguquguqukayo ngokushintsha kancane kancane kanye noshintsho olwenzeka kancane ngokuya ngobude besigaba somkhiqizo.
Ububanzi bezilinganiso bukhulu kakhulu, kusuka kumashubhu amakhulu kakhulu namaphrofayli anezigaba ezinobubanzi bombuthano ongaphandle obungu-500-1000mm kuya kokuncane kakhulu ngokunemba extrusions ezinezigaba ezilingana nezinti zikamentshisi.
