Ka nts'etsopele ea moruo le saense le thekenoloji, litlhoko tsa boleng ba lihlahisoa tsa extruded li phahame le ho feta, 'me litlhoko tse ling tse khethehileng li behiloe likarolong tse ling, tse khothalletsang tsoelo-pele e potlakileng.letlapa la koporothekenoloji ea reverse extrusion.
Mofuta o mocha oa ts'ebetso ea reverse extrusion bakeng sa lakane ea koporo e loketseng litšepe tse fapaneng le li-alloys hammoho le litšepe tse ling e ile ea ntlafatsoa.Ho ea ka tlhokahalo, sebopeho sa koporo ea letlapa la koporo e lula e nchafatsoa le ho ntlafatsoa, 'me e ncha ea reverse extruder e nang le ts'ebeliso e fapaneng le meaho e fapaneng e nts'etsopele.Ho ea ka litlhoko tsa theknoloji ea tlhahiso le boleng ba sehlahisoa, lisebelisoa tse ncha le lisebelisoa tsa extrusion tsa reverse extruder tse nang le sebopeho se secha lia ntlafatsoa.
Melao-motheo e ka sehloohong ea khetho ea theknoloji ea tšepe ea koporo reverse extrusion: (1) ho ea ka litšobotsi tsa phallo ea extrusion e fapaneng ea tšepe, e leng lisebelisoa tse lokelang ho nkoa e le ho sebelisa reverse extrusion e ka khethoa.Ka mohlala, ka hare ho extrusion ea koporo, koporo le lisebelisoa tse ling, ho phalla ha tšepe ho pakeng tsa mofuta oa A le mofuta oa B, 'me phetoho ea mocheso le khatello nakong ea extrusion e nyenyane haholo.Ho molemo ho ntlafatsa ho tšoana ha microstructure le thepa ea lihlahisoa extruded ka ho sebelisa bataletseng die unlubricated reverse extrusion ea koporo lakane le koporo motsoako terata, bareng, profil le phala.
(2) Boemo ba ho ferekanngoa ka ntle bo na le tšusumetso e hlakileng haholo ho phalla ha letlapa la koporo.Maemo a fapaneng a likhohlano a kantle a tla lebisa mefuteng e fapaneng ea phallo ea tšepe.Ka hona, bakeng sa lisebelisoa tse hlokang ho tlotsoa le ho fetisoa, ho molemo ho sebelisa reverse extrusion.
(3) Reverse extrusion e loketse tlhahiso ea extrusion ea lakane ea koporo ka ho nepahala ho phahameng, sebopeho se setle 'me ha ho na selikalikoe sa kristale se mahoashe le mocheso o moqotetsane oa extrusion.Matla a sebetsang holim'a tšepe nakong ea reverse extrusion, le matla a sebetsang holim'a tšepe nakong ea extrusion e ka morao ea lesela la koporo, ha ho na motsamao o lekanyelitsoeng pakeng tsa billet ea tšepe le lakane ea extrusion.
