1 Isingeniso
Ngokuthuthuka okusheshayo komkhakha we-aluminium kanye nokwanda okuqhubekayo kwe-tonnage yemishini yokukhishwa kwe-aluminium, ubuchwepheshe bokukhishwa kwe-aluminium ye-porous mold sekuqhamuke. Ukukhishwa kwe-porous mold aluminium kuthuthukisa kakhulu ukusebenza kahle kokukhiqizwa kokukhishwa futhi kubeka nezimfuno zezobuchwepheshe eziphakeme ku-Mold Design kanye nezinqubo zokukhishwa.
2 inqubo yokukhishwa
Umthelela wenqubo ye-Extresion ekusebenzeni kahle kokukhiqizwa kokukhishwa kwe-Aluminium Mold Aluminium ikakhulukazi kuboniswa ekuphathweni kwezici ezintathu: izinga lokushisa elingenalutho, izinga lokushisa lokubumba kanye nokuphuma kokushisa.
2.1 lokushisa elingenalutho
Ukushisa okungenalutho okufanayo kunomthelela omkhulu ekuphumeni kokukhishwa. Ekukhiqizweni kwangempela, imishini yokukhishwa okuthambekele ekubuyiselweni komhlaba ngokuvamile kufudunyezwa kusetshenziswa izimlilo eziningi ezingenalutho. Izindawo eziningi ezingenalutho zihlinzeka ngokufudumala okuthe xaxa nokufudumeza okugcwele okulula ngezakhiwo ezinhle zokufakelwa. Ngaphezu kwalokho, ukuze kuqinisekiswe ukusebenza kahle okuphezulu, indlela "yokushisa ephansi ne-High Speed" ivame ukuqashwa. Kulokhu, izinga lokushisa elingenalutho kanye nokushisa okuphumayo kufanele kuhambisane kakhulu nesivinini sokukhishwa, ngezilungiselelo ezithathwa izinguquko zengcindezi yokukhishwa kwesimo esingelutho kanye nesimo sendawo engenalutho. Izilungiselelo zokushisa ezingenalutho zincike ezimweni zokukhiqiza zangempela, kepha njengesiqondiso esijwayelekile, ukukhishwa okubumbana kwe-porous, amazinga okushisa angenalutho agcinwa ngokuvamile phakathi kuka-420-450
I-2.2 lokushisa le-milld
Kususelwa kulwazi lokukhiqizwa kwesayithi, amazinga okushisa okubumba kufanele agcinwe phakathi kuka-420-450 ° C. Izikhathi zokushisa ngokweqile zingaholela ekuguguleni isikhunta ngesikhathi sokusebenza. Ngaphezu kwalokho, ukufakwa okulungile kokubumba ngesikhathi sokushisa kubalulekile. Izikhunta akufanele zifakwe kakhulu ndawonye, zishiya isikhala esithile phakathi kwazo. Ukuvimba i-airflow outlet yesithando somlutha noma ukubekwa okungafanele kungaholela ekushiseni okungalingani nokungahambisani.
3 Mold Factors
Idizayini yokubumba, ukulungiswa kokubumba, kanye nokulungiswa kokubumba kubalulekile ukwakheka kokukhishwa futhi kuthinte ngqo ikhwalithi yomkhiqizo, ukunemba okunobukhulu, kanye nokusebenza kahle kokukhiqiza. Ukudweba kusuka ekukhiqizweni kwezinto zokukhiqiza kanye nokuhlangenwe nakho okwabiwe okuhlangenwe nakho kokuhlanganisa, ake sihlaziye lezi zici.
3.1 Design Mold
Isikhunta yisisekelo sokwakheka komkhiqizo futhi kudlala indima ebalulekile ekunqumeni ukwakheka, ukunemba kobukhulu, ikhwalithi ephezulu, kanye nezinto ezibonakalayo, kanye nezinto ezibonakalayo zomkhiqizo. Kumaphrofayili wokubumba ama-porsous anezidingo eziphakeme kakhulu, ukuthuthukisa ikhwalithi ephezulu kungatholakala ngokunciphisa inani le-diversion hole nokwenza kahle ukubekwa kwamabhuloho okuhlobisa. Ngokwengeziwe, ngokufa kwefulethi, kusetshenziswa umdwebo wokugeleza okuguqukayo kungaqinisekisa ukugeleza kwensimbi okufanayo kungene emigqonyeni ye-die.
3.2 Ukucubungula Ukubumba
Ngesikhathi sokucubungula isikhunta, ukunciphisa ukumelana nokugeleza kwensimbi emabhulolini kubalulekile. Ukugaya amabhuloho wokuphambukiswa ngokushelela kuqinisekisa ukunemba kwezikhundla zebhuloho le-dilernsion futhi kusiza ukufeza ukuhamba kwensimbi efanayo. Kumaphrofayli anezidingo ezisezingeni eliphakeme, ezinjengamaphaneli elanga, abheka ukukhulisa ukuphakama kwegumbi lokushiswa noma usebenzisa inqubo ye-welding yesibili yokuqinisekisa imiphumela emihle yokufaka insimbi.
3.3 ukulungiswa kokubumba
Ukulungiswa okujwayelekile kokubumba kubalulekile ngokulinganayo. Polishing izikhunta kanye nokusebenzisa imali ye-nitrogenization kungavimbela izingqinamba ezinjengobulukhuni obungalingani ezindaweni ezisebenzayo zombuso.
4 Ikhwalithi engenalutho
Izinga le-Blank linomthelela obalulekile kwikhwalithi yomkhiqizo, ukusebenza kahle kokukhishwa, kanye nomonakalo wokubumba. Izikhala ezisezingeni eliphansi zekhwalithi zingaholela ezinkingeni ezisezingeni eliphakeme njenge-grooves, ukudilizwa ngemuva kwe-oxidation, futhi kuncishiswe ukubumba impilo. Ikhwalithi engenalutho ifaka phakathi ukwakheka okufanele nokufana kwezinto, zombili ezithinta ngokuqondile ukuphuma kwe-Extresion kanye nekhwalithi ephezulu.
4.1 Ukucushwa Kwokwakheka
Ukuthatha amaphrofayili wephaneli elanga njengesibonelo, ukucushwa okufanele kwe-SI, MG, no-Fe ku-alloy okhethekile ka-6063 wokukhishwa kwesikhunta okuyisisekelo kubalulekile ukuze uzuze ikhwalithi ephezulu yendawo ngaphandle kokuyekethisa imishini. Inani eliphelele kanye nesilinganiso se-SI ne-MG libalulekile, futhi ngokusekelwe ekuhlangenwe nakho kokukhiqiza isikhathi eside, ukulondolozwa kwe-SI + MG ebangeni le-0.82-0.90% kufanelekile ukuthola ikhwalithi ephezulu yobuso.
Ekuhlaziyeni kwezikhala ezingezona ezihambisana namaphaneli elanga, kwatholakala ukuthi umkhondo nokungcola kwayo kwakungazinzile noma kudlule imikhawulo, okuthinta kakhulu ikhwalithi ephezulu. Ukungezwa kwezinto ngesikhathi sokuqalisa esitolo esincibilikayo kufanele kwenziwe ngokunakekela ukugwema ukungazinzi noma okweqile kwezinto ezilandelwayo. Ekuhlukanisweni kwemfucuza embonini, imfucumfucu ye-Extrusion ifaka imfucumfucu ephakeme njengokusikeka kokungasebenzi kanye nezinto zesisekelo, imfucuza yesibili ifaka imfucumfucu yokusebenza kusuka ku-oxidation kanye namaphrofayili wokufakwa kwempuphu, kanye namaphrofayili wokufakwa kwe-thermal ahlukaniswe njengemfucuza ephakeme. Amaphrofayli axedthised kufanele asebenzise okungenalutho okukhethekile, futhi ngokuvamile akukho machithi ozongezwa lapho izinto zokwakha zanele.
4.2 Inqubo Yokukhiqiza Engenalutho
Ukuthola izikhala ezisezingeni eliphakeme, ukubambelela okuqinile kokucubungula izidingo ze-nitrogen zokuhlanza isikhathi nesikhathi sokuxazulula i-aluminium kubalulekile. Izakhi zezabelo zingezwe ngokujwayelekile kwifomu le-block, futhi ukuxubana okuphelele kusetshenziselwa ukusheshisa ukuchithwa kwawo. Ukuxuba okufanele kuvimbela ukwakheka kwezindawo eziphakeme zasendaweni eziphakeme zezakhi ze-alloy.
Ukugcina
Ama-Aluminium Alloys asetshenziswa kabanzi ezimotweni ezintsha zamandla, anezicelo ezakhiweni ezihlelekile kanye nezingxenye ezinjengezimba, injini namasondo. Ukusetshenziswa okwandayo kwama-aluminium embonini yezimoto kuqhutshwa yisidingo sokusebenza kahle kwamandla kanye nokusimama kwemvelo, okuhlanganiswe nentuthuko kubuchwepheshe be-aluminium alloy technology. Kumaphrofayli anezidingo ezisezingeni eliphakeme, njengezinkundla zebhethri ze-aluminium ezinezimbobo eziningi zangaphakathi kanye nezidingo eziphezulu zokusebenza kwemishini, ukwenza ngcono ukusebenza kahle kokukhishwa kwesikhunta okubunjiwe kubalulekile ukuze kukhule kumongo wenguquko yamandla.
