Ukuqalisa
Ngokuthuthukiswa komkhakha wezimoto, imakethe ye-Aluminium Alloy Intactha lemisha ikhula ngokushesha, yize kusasele kancane ngosayizi ophelele. Ngokwesimo sezulu yi-automotive lightweight technology ebuchwepheshe umfelandawonye we-Chinese Aluminium Alloy umthelela emakethe, ngo-2025, ukufunwa kwemakethe kulinganiselwa ukuthi kuzungeze amathani ayi-140,000, ngosayizi wemakethe kulindeleke ukuthi kufinyelele ku-4.8 billion RMB. Ngo-2030, ukufunwa kwemakethe kulindeleke ukuthi kube ngamathani angama-220,000, ngosayizi wemakethe olinganiselwa ku-7.7 billion RMB, kanye nenani lokukhula lonyaka elihlanganisiwe elingaba ngu-13%. Umkhuba wentuthuko wokukhanya okulula nokukhula okusheshayo kwamamodeli wezimoto eziphakathi nendawo eziphakeme kakhulu kubalulekile ukushayela izinto zokuthuthuka kwe-aluminium alloy umthelela wemishayo eChina. Amathemba emakethe wamabhokisi we-aungotive athinta ama-crash athembisa.
Njengoba izindleko zincipha kanye nentuthuko yezobuchwepheshe, ama-aluminium alloy umthelela wemikhumbi kanye namabhokisi wokuphahlazeka aya ngokuya ebanda kakhulu. Njengamanje, asetshenziswa kumamodeli wemoto maphakathi ne-high-end arve as a3, Audi A4L, BMW X1, i-Mercedes-Benz C260, i-Buick Regal, noBuick Lacrosse.
I-Aluminium Alloy Impactic Impams IQHAWULWA ikakhulukazi ama-Umthelela Crossbeams, amabhokisi okuphahlazeka, izisekelo ezikhuphukayo, kanye nemikhono ye-hook, njengoba kukhonjisiwe kuMfanekiso 1.
Umdwebo 1: I-Aluminium Alloy Inomthelela Broung Assembly
Ibhokisi lokuphahlazeka liyibhokisi lensimbi elisendaweni ephakathi komthelela kanye nemishayo emibili emibi yemoto, ngokuyisisekelo esisebenza njengesitsha esidonsa amandla. La mandla abhekisela emandleni omthelela. Lapho imoto ihlangabezana nokushayisana, umthelela wethonya unamandla athile wokuthola amandla. Kodwa-ke, uma amandla edlula umthamo wokugoba umthelela, izodlulisa amandla ebhokisini lokuphahlazeka. Ibhokisi lokuphahlazeka lithatha wonke amandla umthelela futhi azilimaze ngokwalo, aqinisekise ukuthi imishayo ende ihlala ilimazeke.
Izidingo zomkhiqizo ezi-1
1.1 Ubukhulu kufanele banamathele ezimfuneko zokubekezelela umdwebo, njengoba kukhonjisiwe kuMfanekiso 2.
1.3 Izidingo Zokusebenza Kwamakhaya:
Amandla asheshayo: ≥215 MPA
Ukukhiqiza amandla: ≥2055 MPA
Elengation A50: ≥10%
1.4 Ukusebenza kwe-Crash Box Crushct:
Ngasekupheleni kwe-X-axis yemoto, usebenzisa indawo yokushayisana enkulu kunengxenye yesiphambano somkhiqizo, layisha ngejubane le-100 mm / min kuze kube yilapho uchoboza, nenani lokucindezela lama-70%. Ubude bokuqala bephrofayili bungama-300 mm. Emhlanganweni wokuqinisa ubambo odongeni lwangaphandle, imifantu kufanele ibe ngaphansi kwama-15 mm okufanele athathwe amukelwe. Kufanele kuqinisekiswe ukuthi ukuqhekeka okuvunyelwe akukuhlehlisi amandla okuthola amandla ephrofayli, futhi akufanele kube khona imifantu ebalulekile kwezinye izindawo ngemuva kokuchoboza.
2 indlela yokuthuthuka
Ukuhlangabezana ngasikhathi sinye izidingo zokusebenza kwemishini nokusebenza okuchobozayo, indlela yokuthuthuka imi kanjena:
Sebenzisa induku engu-6063b ngokwakheka kwe-alloy eyinhloko ye-SI 0.38-0.41% ne-MG 0.53-0.60%.
Yenza umoya ocimisa umoya nokuguga kokufakelwa ukuze uzuze isimo se-T6.
Sebenzisa inkungu + umoya ocimisa futhi wenze ukwelashwa okuguga kakhulu ukuze kufinyelelwe isimo se-T7.
Ukukhiqizwa kwe-Pilot 3
3.1 izimo zokukhishwa
Ukukhiqizwa kwenziwa ngo-2000t ukukhishwa kwesilinganiso sokukhishwa kwesilinganiso esingu-36. Izinto ezisetshenzisiwe yi-Aluminium ROD 6063B. Amazinga okushisa okushisa we-aluminium rod anjengokulandelayo: IV ZONE 450 -IZO ZONKE 470-II ZONKE 490-1 ZONKE 490-1 Indawo engu-219. . Ijubane leShaff le-Extrusion lingu-2,5 mm / s, kanye nesivinini sokukhishwa kwephrofayili yi-5.3 m / imiz. Izinga lokushisa endaweni yokukhishwa kungu-500-540 ° C. Ukuqedwa kwenziwa kusetshenziswa ukupholisa komoya ngamandla wabalandeli kwesokunxele ku-100%, amandla aphakathi aphakathi ku-100%, namandla okuhola ku-50%. Izinga eliphakathi nendawo eliphakeme ngaphakathi kwendawo elicijile lifinyelela kuma-300-350 ° C / min, kanye namazinga okushisa ngemuva kokuphuma endaweni eqeda ukuqeda kungama-60-180 ° C. Okwesici + amoyeni aqedile, izinga eliphakathi nendawo eliphakeme ngaphakathi kwendawo yokushisa lifinyelela ku-430-480 ° C / min, kanye namazinga okushisa ngemuva kokuphuma endaweni eqeda ukuqeda kungu-50-70 ° C. Iphrofayili ayibonisiso ukugoba okubalulekile.
3.2 Ukuguga
Ukulandela inqubo yokuguga kwe-T6 ngo-185 ° C amahora angu-6, ubulukhuni bezinto ezibonakalayo kanye nezindawo zemishini zinjengokulandelayo:
Ngokusho kwenqubo yokuguga kwe-T7 ku-210 ° C amahora angama-6 namahora ayi-8, ubulukhuni bokwenziwa kanye nezindawo zemishini kungokulandelayo:
Kususelwa kwimininingwane yokuhlola, indlela yokucinga yenkungu + yomoya, ehlanganiswe nenqubo yokuguga ka-210 ° C / 6h, ihlangabezana nezidingo zokusebenza kwemishini nokuhlolwa okuchobozayo. Uma kucatshangelwa ukusebenza kwezindleko, indlela yokuqothula yomoya + nenqubo yokuguga komoya engu-210 ° C / 6H yakhethwa ukuze kukhiqizwe ukufeza izidingo zomkhiqizo.
3.3 Ukuhlolwa okuchobozekile
Okwezinduku zesibili nezesithathu, ukuphela kwekhanda kunqunywa yi-1.5m, futhi ukuphela komsila kunqunywe ngu-1.2m. Amasampula amabili ngamunye athathwa ekhanda, emaphakathi, nasemisipha izingxenye, ubude bama-300mm. Ukuhlolwa okuchobozekile kwenziwa ngemuva kokuguga ngo-185 ° C / 6H no-210 ° C / 6H kanye ne-8h (idatha yokusebenza kwemishini njengoba kushiwo ngenhla) emshinini wokuhlola wezinto ezibonakalayo. Ukuhlolwa kwenziwa ngejubane lokulayisha lama-100 mm / min ngenani lokucindezela lama-70%. Imiphumela imi ngalendlela elandelayo: Ngomoya we-ARID + ecinisa izinqubo zokuguga ezingama-210 .
Ngokusekelwe kwimiphumela yokuhlola ecindezelayo, i-Air + Air iqonde ngenqubo yokuguga engama-210 ° C / 6h kanye ne-8h ihlangabezana nezidingo zekhasimende.
4 Isiphetho
Ukusebenziseka kahle kwezinqubo zokugunda nokuguga kubalulekile ekuthuthukisweni okuphumelelayo komkhiqizo futhi kunikeze isisombululo esifanele senqubo yomkhiqizo webhokisi lokuphahlazeka.
Ngokuhlola okubanzi, kunqunywe ukuthi isimo sezinto ezibonakalayo somkhiqizo webhokisi lokuphahlazeka kufanele kube ngu-6063-T7, indlela yokuqeda umoya Ngamazinga okushisa asukela ku-480-500 ° C, isivinini sokukhishwa kweShaff of 2 mm / s, ukukhiqizwa kokufa okufayo kwe-480 ° C, kanye nokushisa kwe-extresion ye 500-540 ° C.
