Emikhakheni yokukhiqiza kanye nobunjiniyela bokunemba obusezingeni eliphezulu, ama-aluminium alloys asephenduke izinto zokwakha ezingenakutshintshwa ngenxa yezakhiwo zawo ezilula nezinamandla aphezulu. Phakathi kwazo,Ibha ye-aluminium eyenziwe nge-7075 T652Ivelele njengomkhiqizo we-aluminium alloy osezingeni eliphezulu, oyingxenye yochungechunge lwe-Al-Zn-Mg-Cu lwe-aluminium alloys enamandla kakhulu. Iyaziwa kabanzi ezindizayo, imishini yezempi, imishini enembile kanye neminye imboni edingeka kakhulu ngenxa yezakhiwo zayo ezivelele zemishini kanye nokuqina kobukhulu.
Ukwakheka Kwamakhemikhali kwe-7075 T652 Forged Aluminium Bar
Ukusebenza okuphezulu kwebha ye-aluminium eyenziwe nge-7075 T652 kunqunywa ngokuyisisekelo yisilinganiso sayo sokwakheka kwamakhemikhali esinembile, esihambisana ngokuqinile nezindinganiso zomhlaba wonke ezifana ne-ASTM B247, i-AMS 4140 kanye ne-QQ-A-250/24. Izinto eziyinhloko zamakhemikhali (ingxenye yesisindo) yilezi ezilandelayo:
I-Aluminium (Al) ingama-90.7% ~ 94.7%, isebenza njengesici se-matrix ukuqinisekisa ukumelana okuyisisekelo kokukhanya nokugqwala kwe-alloy.
I-Zinc (Zn) iyisici esiyinhloko sokuqinisa, esinokuqukethwe okungu-5.1% ~ 6.1%, esakha inhlanganisela enamandla kakhulu ye-intermetallic ene-magnesium nethusi ukuze kuthuthukiswe kakhulu amandla okuthamba kanye nokuqina kwe-alloy.
Okuqukethwe kwe-magnesium (Mg) kungu-2.1% ~ 2.9%, kuhambisana ne-zinc ukuthuthukisa umphumela wokuqina kwemvula nokukhulisa amandla okukhiqiza kwe-alloy.
Okuqukethwe kwethusi (Cu) kungu-1.2% ~ 2.0%, okuthuthukisa amandla e-alloy kanye nokulinganisela kokuqina kwayo, ngenkathi kuthuthukiswa ukumelana kwayo nokugqwala kokucindezeleka.
Ngaphezu kwalokho, inani elincane le-Chromium (Cr 0.18% ~ 0.28%) liyangezwa ukuze kulungiswe isakhiwo sezinhlamvu, kususwe amaphutha angaphakathi, futhi kuthuthukiswe ukumelana kokukhathala kwe-alloy, ngokulawula okuqinile kwezinto ezingcolile njengensimbi ne-silicon ukuqinisekisa ubumsulwa kanye nokuqina kokusebenza kwebha ehlanganisiwe.
Le nsimbi eqondile ehambisana ne-element endows 7075 T652 eyenziwe nge-aluminium bar enesisekelo esiqinile, igwema amaphutha okusebenza abangelwa okuqukethwe ngokweqile noma okunganele kwe-element, futhi ibeka isisekelo esiqinile sezakhiwo zayo ezinhle kakhulu zemishini kanye nokusebenza kokucubungula.
Izici Zokusebenza Okuyinhloko ze-7075 T652 Forged Aluminium Bar
Ibha ye-aluminium eyenziwe nge-7075 T652 icutshungulwa ngokusebenzisa ukubumba okunembile, ukwelashwa kokushisa kwesisombululo, ukucindezela kokucindezeleka kanye nokuguga okwenziwe (i-T652 temper), okuhlanganisa kahle izinzuzo zokubumba kanye nokwelashwa kokushisa, okwethula isethi yezinkomba zokusebenza ezinhle kakhulu ezihlangabezana nezidingo zokukhiqiza okusezingeni eliphezulu.
Ngokuphathelene nezakhiwo zemishini, inamandla okudonsa aphezulu kakhulu kanye namandla okukhiqiza, inamandla okudonsa afinyelela ku-570 ~ 590 MPa kanye namandla okukhiqiza angu-475 ~ 505 MPa, aqhathaniswa nensimbi yekhabhoni ephakathi nendawo enobukhulu obuyi-1/3 kuphela bensimbi, ifinyelela ibhalansi efanele phakathi komthamo olula nowokuthwala umthwalo. Ubulukhuni bayo beBrinell bufinyelela ku-150 ~ 160 HB, bunokumelana okuhle kakhulu nokuguguleka kanye nekhono lokulwa nokuguquka, elifanele ukukhiqiza izingxenye ezithwala umthwalo omkhulu. Okwamanje, i-T652 temperature isebenzisa ukukhululeka kokucindezeleka kokucindezela okungu-1% -5% ngemva kokwelashwa kwesisombululo, isusa ngokuphelele ukucindezeleka kwangaphakathi okusele okudalwe enkambisweni yokwelapha nokushisa, iqinisekisa ukuzinza okuhle kakhulu ngesikhathi sokukhiqiza nokusetshenziswa kwesikhathi eside, igwema ukugoba, ukuguqulwa kanye nokuphambuka kosayizi, okubaluleke kakhulu ezingxenyeni zokukhiqiza ngokunemba.
Ngokuvumelana nezimo zemvelo, inamandla amahle okukhathala kanye nokuqina komthelela, iyakwazi ukumelana nemithwalo ephindaphindwayo eshintshanayo kanye nomthelela osheshayo ngaphandle kokuphuka, ifanelekela isevisi yesikhathi eside ezimweni zokusebenza eziyinkimbinkimbi. Nakuba ukumelana kwayo nokugqwala kubuthakathaka kunokwe-5000 series aluminium alloys, ukwelashwa okufanele kwendawo efana ne-anodizing kanye ne-coating kungathuthukisa ngempumelelo ukumelana kwayo nokugqwala, kwandise ububanzi bokusetshenziswa kwayo. Iphinde ibe nokusebenza kahle komshini, ingakwazi ukuzivumelanisa nokujika, ukugaya, ukubhoboza kanye nezinye izinqubo zomshini wokunemba, futhi kulula ukwakha izingxenye zesakhiwo eziyinkimbinkimbi, ihlangabezana nezidingo zokucubungula ezinembile kakhulu zemishini ephezulu.
Ububanzi Bokusetshenziswa kwe-7075 T652 Forged Aluminium Bar
Ngokuncika ezinzuzweni zayo zokusebenza eziphelele,Ibha ye-aluminium eyenziwe nge-7075 T652isetshenziswa kabanzi emikhakheni enezidingo eziphezulu kakhulu zamandla ezinto ezibonakalayo, ukuqina okulula nobukhulu, okuhlanganisa izimboni eziningi zokukhiqiza eziyinhloko ekhaya nakwamanye amazwe.
Embonini yezindiza, iyinto ekhethwayo yezingxenye ezibalulekile zesakhiwo, ezisetshenziselwa ukukhiqiza ama-wing spar ezindiza, ozimele be-fuselage, izingxenye zegiya lokufika, izingxenye zesakhiwo sesathelayithi kanye nezingxenye ezithwala umthwalo werokhethi. Amandla ayo aphezulu kanye nezakhiwo zayo ezilula kunciphisa ngempumelelo isisindo semishini yezindiza, kuthuthukisa umthwalo okhokhelwayo kanye nokusebenza kahle kukaphethiloli, futhi kuqinisekiswe ukuphepha nokuzinza kwemishini ngaphansi kwezimo zokusebenza ezimbi kakhulu.
Emkhakheni wezempi nowokuvikela, isetshenziswa kabanzi ekukhiqizweni kwe-chassis yezimoto zempi, izingxenye zesistimu yezikhali, amagobolondo ezinsimbi anembile kanye nezingxenye ezivikelwe. Ukumelana kwayo nomthelela omkhulu kanye nomthamo wayo wokuthwala umthwalo kuqinisekisa ukuthembeka nokuqina kwemishini yezempi ezindaweni zempi ezinzima, ihlangabezana nezindinganiso eziqinile zokukhiqiza ezempi.
Embonini yokukhiqiza imishini enembile kanye nesikhunta, isetshenziselwa ukucubungula imiphini yemishini enembile kakhulu, izinto zokufaka amathuluzi, izinto zokufaka isikhunta kanye nezingxenye zemishini ezenzakalelayo. Ukuqina kwayo okuhle kakhulu kanye nokukwazi kwayo ukusebenza kahle kuqinisekisa ukunemba komshini kanye nokuphila kwenkonzo yezingxenye, kunciphisa izinga lokungcola okubangelwa ukuguquka kwezinto.
Ngaphezu kwalokho, isetshenziswa nasezingxenyeni zezimoto ezisebenza kahle kakhulu, izingxenye zomjaho, imishini yezemidlalo esezingeni eliphezulu (njengezinhlaka zamabhayisikili, imishini yokukhwela izintaba) kanye nezingxenye zokunemba kolwandle, okunikeza ukusebenza okugcwele ezinzuzweni zayo zamandla aphezulu, ezilula kanye nokumelana nokugqwala ngemva kokwelashwa kwendawo, okuhlangabezana nezidingo zokusebenza okuphezulu zezimboni ezahlukene.
Ibha ye-aluminium eyenziwe ngobumba engu-7075 T652 iwumkhiqizo we-aluminium alloy osebenza kahle kakhulu onezakhiwo ezinhle kakhulu eziphelele, futhi ukwakheka kwayo kwamakhemikhali okuhlukile kanye nenqubo ekhethekile yokwelapha ukushisa kwenza kube nezinzuzo ezingenakuqhathaniswa ezimweni zokusetshenziswa ezinamandla aphezulu, ezinembile kakhulu nezilula. Njengomhlinzeki ochwepheshe wemikhiqizo ye-aluminium, sinikeza imigoqo ye-aluminium eyenziwe ngobumba engu-7075 T652 enemininingwane ephelele, ukusebenza okuzinzile kanye nokuhambisana nezindinganiso zomhlaba wonke, kusekela ukucubungula okwenziwe ngokwezifiso kanye nezinsizakalo zomshini wokunemba. Kungakhathaliseki ukuthi uhilelekile ekukhiqizeni izindiza, ekukhiqizeni imishini yezempi noma ekucubungulweni kwemishini yokunemba, yethuImigoqo ye-aluminium eyenziwe nge-7075 T652ingahlangabezana nezidingo zakho eziqinile zezinto ezibonakalayo, ikusize uthuthukise ikhwalithi yomkhiqizo kanye nokuncintisana emakethe. Siyakwamukela ukuthi usithinte ukuze uthole imininingwane eningiliziwe yemingcele yomkhiqizo, izingcaphuno kanye nezixazululo ezenziwe ngokwezifiso.
