Ngokuthuthuka komnotho nesayensi nobuchwepheshe, izidingo zekhwalithi zemikhiqizo ekhishwe ziphakeme kakhulu, futhi ezinye izidingo ezikhethekile zibekwe phambili kwezinye izici, ezikhuthaza ukuthuthuka okusheshayoishidi lethusireverse extrusion technology.
Kwasungulwa uhlobo olusha lwenqubo ye-reverse extrusion yeshidi lethusi elifanele izinsimbi ezihlukahlukene nama-alloys kanye nezinye izinsimbi.Ngokwesidingo, ukwakheka kwe-brass sheet extruder kuhlala kusungulwa futhi kuthuthukiswa, futhi i-extruder entsha ehlanekezela ukusetshenziswa okuhlukile nezakhiwo ezahlukahlukene ziyathuthukiswa.Ngokwezidingo zobuchwepheshe bokukhiqiza kanye nekhwalithi yomkhiqizo, izinto ezisetshenziswayo zokufa kanye nentsha ye-extrusion ye-reverse extruder enesakhiwo esisha ziyathuthukiswa.
Izimiso eziyinhloko zokukhethwa kobuchwepheshe be-reverse extrusion yeshidi lethusi: (1) ngokusho kwezici zokugeleza ze-extrusion yensimbi ehlukene, iziphi izinto okufanele zicatshangelwe ukuthi zisebenzisa i-extrusion reverse zinganqunywa.Isibonelo, ku-extrusion engemuva yethusi, ithusi namanye ama-alloys, ukugeleza kwensimbi kuphakathi kohlobo A nohlobo B, futhi ukuguqulwa kwezinga lokushisa nokucindezela ohlelweni lwe-extrusion kuncane kakhulu.Kuyazuzisa ukuthuthukisa ukufana kwe-microstructure kanye nezakhiwo zemikhiqizo ekhishwe ngokusebenzisa i-flat die unlubricated reverse extrusion yeshidi lethusi kanye ne-copper alloy wire, ibha, iphrofayili kanye nepayipi.
(2) Isimo sokungqubuzana sangaphandle sinethonya elisobala kakhulu ekuhambeni kweshidi lethusi.Izimo ezihlukene zokungqubuzana kwangaphandle zizoholela ezinhlotsheni ezahlukene zokugeleza kwensimbi.Ngakho-ke, ezintweni ezidinga ukugcotshwa nokukhishwa, kuzuzisa kakhulu ukusebenzisa i-reverse extrusion.
(3) I-reverse extrusion ifaneleka ekukhiqizweni kweshidi lethusi elinembayo eliphezulu, isakhiwo esihle futhi ayikho indandatho yekristalu emahhadla kanye nobubanzi obuncane bezinga lokushisa lomoya.Amandla asebenza ensimbi ngesikhathi sokuhlehla kwe-extrusion, namandla asebenza ensimbi ngesikhathi sokuhlehla komugqa wethusi, akukho ukunyakaza okuhlobene phakathi kwe-billet yensimbi neshidi lokukhipha.
