Extrusionyinkqubo apho iinxalenye zentsimbi ezinde ezithe tye zinokuveliswa.I-cross-sections enokuveliswa iyahluka ukusuka kwingqukuva eqinileyo, uxande, ukuya kwiimilo ze-L, iimilo ze-T.Imibhobho kunye nezinye iintlobo ezininzi ezahlukeneyo.I-extrusion yenziwa ngokukhama isinyithi kwindawo evaliweyo ngesixhobo, esaziwa ngokuba yi-die usebenzisa nokuba ngumatshini okanye ucinezelo lwe-hydraulic.
I-Extrusion ivelisa amandla oxinzelelo kunye nokucheba kwisitokhwe.Akukho tensile eveliswayo, eyenza deformation eliphezulu kunokwenzeka ngaphandle kokukrazula isinyithi.Umngxunya apho i-raw material iqulethwe khona ifakwe i-resistant material.Oku kunokumelana nemithwalo ephezulu ye-radial eyenziwa xa izinto zityhalwa ifa.
Izandiso, zihlala zinciphisa imfuno yomatshini wesibini, kodwa azikho ngokuchanekileyo komgangatho ofanayo okanye ukugqitywa komphezulu njengamalungu omatshini.Ukugqitywa komphezulu wentsimbi yi-3um;(125 uin), kunye neAluminiyam kunye neMagnesium yi-0.8 um (30 uin).Nangona kunjalo, le nkqubo inokuvelisa iindidi ezininzi ezinqamlezileyo ezinzima ukuvelisa iindleko ezisebenzayo usebenzisa ezinye iindlela.Ubuncinci bentsimbi bumalunga ne-3 mm (0.120 ngaphakathi), kanti i-Aluminiyam neMagnesium imalunga ne-1mm (0.040 in).Ubuncinci amacandelo anqamlezayo angama-250 mm2 (0.4 in2) yentsimbi kwaye ngaphantsi kweAluminiyam kunye neMagnesium.Ubuncinci bekona kunye ne-fillet radii yi-0.4 mm (0.015 in) ye-Aluminium kunye ne-Magnesium, kunye nentsimbi, i-radius yekona encinci yi-0.8mm (0.030 in) kunye ne-4 mm (0.120 in) i-fillet radius.
Ukukhupha okubandayo:I-extrusion ebandayo yinkqubo eyenziwa kwiqondo lokushisa legumbi okanye amaqondo obushushu aphakamileyo.Le nkqubo inokusetyenziselwa izinto ezininzi-kuxhomekeke ekuyileni izixhobo eziqinileyo ezinokumelana noxinzelelo oludalwe yi-extrusion.Imizekelo yeentsimbi ezinokuthi zikhutshwe yilothe, i-tin, i-aluminium alloys, ubhedu, i-titanium, i-molybdenum, i-vanadium, isinyithi.Imizekelo yamacandelo akhutshiweyo abandayo ziityhubhu eziqengqelekayo, iinkonkxa ze-aluminiyam, iisilinda, iintsimbi ezingenanto.Uncedo lwe-extrusion ebandayo zezi:
- * Akukho oxidation eyenzekayo
- *Iimpawu ezilungileyo zoomatshini ngenxa yokusebenza okubandayo okugqithisileyo okoko nje amaqondo obushushu adalwe angaphantsi kweqondo lobushushu le-crystallization
- *Ukugqitywa kakuhle komphezulu kusetyenziswa izithambiso ezifanelekileyo
I-Hot Extrusion:I-extrusion eshushu yenziwa kumaqondo obushushu aphezulu, malunga ne-50 ukuya kwi-75% yendawo yokunyibilika kwesinyithi.Uxinzelelo lunokuvela kwi-35-700 MPa (5076 - 101,525 psi).Ngenxa yobushushu obuphezulu kunye noxinzelelo kunye nefuthe layo elibi kubomi bokufa kunye namanye amacandelo, ukuthambisa okulungileyo kuyadingeka.I-oyile kunye negraphite zisebenza kumaqondo aphantsi, ngelixa kubushushu obuphezulu kusetyenziswa umgubo weglasi.
Iinxalenye eziqhelekileyo eziveliswa yi-extrusions ziyinxalenye ye-trim esetyenziswa kwi-automotive kunye nezicelo zokwakha, amalungu efreyimu yefestile, iintsimbi, iindawo zesakhiwo seenqwelomoya.
