I-Aluminium Extrusions

I-Extrusioninqubo lapho izingxenye zensimbi eziqondile ezinde zingakhiqizwa.Izingxenye eziphambanayo ezingakhiqizwa ziyahlukahluka ukusuka koyindilinga oqinile, unxande, kuya kumomo ongu-L, umumo we-T.Amashubhu nezinye izinhlobo eziningi ezahlukene.I-extrusion yenziwa ngokucindezela insimbi endaweni evaliwe ngokusebenzisa ithuluzi, elaziwa ngokuthi i-die kusetshenziswa umshini wokunyathelisa ngomshini noma we-hydraulic.

I-Extrusion ikhiqiza amandla acindezelayo kanye ne-shear esitokisini.Akukho ukuqina okukhiqizwayo, okwenza ukuguqulwa okuphezulu kwenzeke ngaphandle kokudabula insimbi.Imbobo lapho impahla eluhlaza kuqukethwe khona ilayishwe ngezinto ezingagugi.Lokhu kungamelana nemithwalo ephezulu yama-radial edalwa lapho impahla iphushwa idayizi.

Ama-extrusions, ngokuvamile anciphisa isidingo somshini wesibili, kodwa awekho ukunemba kwe-dimensional efanayo noma ukuphela kwendawo njengezingxenye eziwumshini.Isiphetho sensimbi singu-3um;(125 uin), kanti i-Aluminium neMagnesium ingu-0.8 um (30 uin).Kodwa-ke, le nqubo ingakhiqiza izinhlobonhlobo eziningi ze-cross-section okunzima ukuzikhiqiza ngendlela engabizi kakhulu usebenzisa ezinye izindlela.Ubuncane bokujiya bensimbi bungaba ngu-3 mm (0.120 in), kanti i-Aluminium neMagnesium icishe ibe ngu-1mm (0.040 in).Izingxenye eziyisiphambano ezincane zingu-250 mm2 (0.4 in2) zensimbi futhi zingaphansi kwalokho ze-Aluminium neMagnesium.Ubuncane bekhona kanye ne-fillet radii ngu-0.4 mm (0.015 in) we-Aluminium ne-Magnesium, futhi ngensimbi, irediyasi yekhona encane ingu-0.8mm(0.030 in) kanye no-4 mm (0.120 in) irediyasi ye-fillet.

I-Cold Extrusion:I-Cold extrusion inqubo eyenziwa ekamelweni lokushisa noma emazingeni okushisa aphakeme kancane.Le nqubo ingasetshenziselwa izinto eziningi-kuncike ekudizayineni amathuluzi aqinile angakwazi ukumelana nezingcindezi ezidalwe yi-extrusion.Izibonelo zezinsimbi ezingakhishwa umthofu, ithini, ama-alloys e-aluminium, ithusi, i-titanium, i-molybdenum, i-vanadium, insimbi.Izibonelo zezingxenye ezikhishwa ngamakhaza amashubhu agoqekayo, amathini e-aluminium, amasilinda, izikhala zamagiya.Izinzuzo ze-extrusion ezibandayo ziyi:

• * Ayikho i-oxidation eyenzekayo
• *Izakhiwo ezinhle zemishini ngenxa yokusebenza kwamakhaza ashubile inqobo nje uma amazinga okushisa adaliwe engaphansi kwezinga lokushisa le-crystallization kabusha
• *Ukuqedwa kahle kwendawo ngokusetshenziswa kwezinto zokugcoba ezifanele

I-Hot Extrusion:I-extrusion eshisayo yenziwa emazingeni okushisa aphezulu, cishe ama-50 kuya ku-75 % wendawo encibilikayo yensimbi.Izingcindezi zingasukela ku-35-700 MPa (5076 - 101,525 psi).Ngenxa yamazinga okushisa aphezulu kanye nezingcindezi kanye nomthelela wayo olimazayo empilweni yokufa kanye nezinye izingxenye, ukugcotshwa okuhle kuyadingeka.Uwoyela negraphite zisebenza emazingeni okushisa aphansi, kanti emazingeni okushisa aphezulu kusetshenziswa impushana yengilazi.

Izingxenye ezijwayelekile ezikhiqizwe ama-extrusions yizingxenye zokunquma ezisetshenziswa kwezezimoto nezokwakha, amalungu ohlaka lwamafasitela, izinsimbi, izingxenye zesakhiwo sendiza.
