Ngophuhliso loqoqosho kunye nesayensi kunye netekhnoloji, iimfuno zomgangatho weemveliso ezigqithisiweyo ziphezulu kwaye ziphezulu, kwaye ezinye iimfuno ezikhethekileyo zibekwe phambili kwezinye iinkalo, ezikhuthaza uphuhliso olukhawulezayo.ishidi lobhedureverse iteknoloji extrusion.
Kwaphuhliswa uhlobo olutsha lwenkqubo yokubuyisela umva i-reverse extrusion yephepha lobhedu elilungele iintlobo ngeentlobo zesinyithi kunye nealloys kunye nezinye iintsimbi.Ngokwemfuno, ulwakhiwo lwe-extruder yobhedu luhlala luhlaziywa kwaye luphuculwa, kwaye i-extruder entsha ye-reverse enokusetyenziswa ngokuhlukileyo kunye nezakhiwo ezahlukeneyo ziyaphuhliswa.Ngokweemfuno zobuchwepheshe bemveliso kunye nomgangatho wemveliso, izixhobo zokufa kunye nezixhobo ezintsha ze-extrusion ze-reverse extruder kunye nesakhiwo esitsha ziyaphuhliswa.
Imigaqo ephambili yokukhethwa kwephepha lobhedu le-teknoloji ye-reverse extrusion: (1) ngokweempawu zokuhamba kwe-extrusion yensimbi eyahlukeneyo, ezo zinto kufuneka ziqwalaselwe ukusebenzisa i-reverse extrusion inokumiselwa.Ngokomzekelo, kwi-reverse extrusion yobhedu, ubhedu kunye nezinye i-alloys, ukuhamba kwesinyithi kuphakathi kohlobo lwe-A kunye nohlobo lwe-B, kunye nokutshintsha kweqondo lokushisa kunye noxinzelelo kwinkqubo yokukhupha incinci kakhulu.Kuyinzuzo ukuphucula ukufana kwe-microstructure kunye neepropati zeemveliso ezigqithisiweyo ngokusebenzisa i-flat die unlubricated reverse extrusion yephepha lobhedu kunye nocingo lwe-alloy yobhedu, ibha, iprofayili kunye nombhobho.
(2) Umqathango wangaphandle we-friction unempembelelo ecacileyo kakhulu ekuhambeni kwephepha lobhedu.Iimeko ezahlukeneyo zokukhuhlana zangaphandle ziya kukhokelela kwiindidi ezahlukeneyo zokuhamba kwesinyithi.Ngoko ke, kwizinto ezifuna ukuthanjiswa kunye nokukhutshwa, kunenzuzo ngakumbi ukusebenzisa i-reverse extrusion.
(3) Ukubuyisela umva i-extrusion ifanelekile kwimveliso ye-extrusion yephepha lobhedu ngokuchaneka okuphezulu, isakhiwo esihle kwaye akukho msesane wekristale onqabileyo kunye nobubanzi obumxinwa beqondo lokushisa.Amandla asebenza kwisinyithi ngexesha lokubuyisela umva, kunye namandla asebenza kwintsimbi ngexesha lokuphinda ubuyele kwi-strip yobhedu, akukho ntshukumo ehambelanayo phakathi kwebillet yesinyithi kunye neshiti le-extrusion.
