Nekuvandudzwa kwehupfumi nesainzi uye tekinoroji, izvo zvinodikanwa zvemhando yezvigadzirwa zveextruded zvakakwira uye zvakakwirira, uye zvimwe zvakakosha zvinoiswa pamberi mune zvimwe zvinhu, zvinokurudzira kukurumidza kusimudzirapepa rendarirareverse extrusion tekinoroji.
Rudzi rutsva rwereverse extrusion process yebras sheet yakakodzera simbi dzakasiyana-siyana uye alloys pamwe chete nedzimwe simbi dzakagadzirwa.Zvinoenderana nezvinodiwa, chimiro chebrass sheet extruder chinogara chichigadzirwa uye kuvandudzwa, uye iyo itsva reverse extruder ine mashandisirwo akasiyana uye akasiyana masisitimu anogadzirwa.Zvinoenderana nezvinodiwa tekinoroji yekugadzira uye mhando yechigadzirwa, iyo inofa uye nyowani extrusion maturusi ezve reverse extruder ane chimiro chitsva anogadzirwa.
Misimboti mikuru yekusarudzwa kwendarira sheet reverse extrusion tekinoroji: (1) zvinoenderana nekuyerera maitiro eakasiyana simbi extrusion, izvo zvinhu zvinofanirwa kutariswa kushandisa reverse extrusion inogona kutsanangurwa.Semuenzaniso, mune reverse extrusion yemhangura, ndarira uye mamwe maalloys, iyo simbi inoyerera iri pakati pemhando A uye mhando B, uye shanduko yekushisa uye kumanikidza munzira yeextrusion idiki kwazvo.Izvo zvinobatsira kuvandudza kufanana kweiyo microstructure uye zvivakwa zve extruded zvigadzirwa uchishandisa flat die unlubricated reverse extrusion yendarira sheet uye copper alloy waya, bar, mbiri uye pombi.
(2) Mamiriro ekunze ekukwenya ane pesvedzero iri pachena pakuyerera kwepepa rendarira.Mamiriro akasiyana ekunze ekunze anozotungamira kumhando dzakasiyana dzekuyerera kwesimbi.Nokudaro, kune zvinhu zvinoda kuomeswa uye kubudiswa, zvinonyanya kubatsira kushandisa reverse extrusion.
(3) Reverse extrusion inokodzera iyo extrusion kugadzirwa kwendarira sheet ine yakanyanya kurongeka, yakanaka chimiro uye isina coarse crystal mhete uye nhete extrusion tembiricha renji.Simba rinoshanda pasimbi panguva yekudzosera kumashure, uye simba rinoshanda pasimbi panguva yekudzosera kumashure kwebrass strip, hapana hukama hwekufamba pakati pesimbi billet uye extrusion sheet.
