Isitsha Sethangi Lamanzi Eligoqekile Elishisayo Ipuleti Lebhoyila Lensimbi Esetshenzisiwe A516-70
I-Q460 iyinsimbi enamandla amakhulu ene-alloy ephansi. Indlela yokuqokwa kwe-Q460: inombolo yayo yensimbi iqanjwe ngo-"Q", emele iphuzu lokukhiqiza lensimbi, okungukuthi, amandla okukhiqiza. Inombolo elandelayo ikhombisa ukuthi inani lephuzu lokukhiqiza elingu-460 limelela i-460 MPa, i-mega ingamandla esi-6 kwangu-10, kanti i-Pa iyiyunithi yokucindezela i-Pascal. I-Q460 isho ukuthi ukuguqulwa kwensimbi ngepulasitiki kuzokwenzeka kuphela lapho amandla ensimbi efika ku-460 MPa, okungukuthi, lapho amandla angaphandle ekhishwa, insimbi ingagcina kuphela isimo esicindezelwe futhi ayikwazi ukubuyela esimweni sayo sokuqala. La mandla makhulu kunensimbi evamile. Izimpawu zezinga lekhwalithi ejwayelekile yi-A, B, C, D, E, ngokulandelana. Ngokusekelwe ekuqinisekiseni okulingana nekhabhoni ephansi, i-Q460 ikhulisa ngokufanele okuqukethwe kwezinto ezincane. Ukusebenza kahle kokushisela kudinga okulingana nekhabhoni ephansi, futhi ukwanda kwezinto ezincane ezincibilikisayo kwandisa amandla ensimbi ngenkathi kukhulisa okulingana nekhabhoni yensimbi. Kodwa ngenhlanhla, i-carbon equivalent eyengeziwe incane, ngakho ngeke ithinte ukusebenza kwensimbi yokushisela.
Intuthuko esheshayo yemboni yezimoto idlale indima ebalulekile ekuthuthukisweni komnotho kanye nomphakathi kuzwelonke. Kodwa-ke, ngenxa yomthelela wokuntuleka kwamandla, ukungcola kwemvelo kanye nezinye izinkinga, ukuphikisana ekuthuthukisweni kwemboni kuye kwagqama kakhulu. Uma sibheke phambili esikhathini esizayo, intuthuko yemboni ingaba yinto eqhubekayo kuphela uma isekelwe emlandweni wemvelo, i-ecology, ukongiwa kwamandla kanye nokuphepha.
Ngaphansi kwalesi sizinda, ukusetshenziswa kwensimbi elula neqinile yezimoto sekuyindlela ebalulekile yokuthuthukiswa. Kodwa-ke, ngokuthuthukiswa kwamandla epuleti lensimbi enamandla aphezulu, inqubo yendabuko yokunyathela ebandayo ithambekele ekuqhekekeni enkambisweni yokwakha, engakwazi ukuhlangabezana nezidingo zokucubungula ipuleti lensimbi enamandla aphezulu. Kulokhu, ubuchwepheshe bokwakha ukunyathela okushisayo kwepuleti lensimbi enamandla aphezulu kakhulu buye bafundwa kancane kancane emhlabeni - inqubo entsha ehlanganisa ukwakheka, ukudluliselwa kokushisa kanye nokuguqulwa kwesakhiwo esincane, esebenzisa kakhulu izici zokwanda kwe-plasticity kanye namandla ancishisiwe ensimbi yeshidi esimweni se-austenite yokushisa okuphezulu. Kodwa-ke, i-thermoforming idinga ucwaningo olujulile ngezimo zenqubo, ukuguqulwa kwesigaba sensimbi kanye nobuchwepheshe bokuhlaziya i-CAE, kodwa lobu buchwepheshe bulawulwa ngabakhiqizi bangaphandle futhi buthuthuka kancane eShayina.
Ngokusho kocwaningo kanye nezibalo, ukusetshenziswa kwensimbi enamandla amakhulu kwezinye izinhlobo zezimoto kuyanda, futhi ukusetshenziswa kwensimbi enamandla aphezulu ohlaka lomzimba lwamamodeli athile kufinyelele ku-90%. Ngokusho kocwaningo lomnyango wezamandla we-American Iron and Steel Institute, noma ngabe inani lensimbi enamandla aphezulu lincishisiwe, ukucindezeleka kwayo kunzima kakhulu kunepuleti elibandayo lendabuko. Ukuguquguquka kwensimbi enamandla aphezulu kuyingxenye nje yensimbi evamile.
Uma izinto zakhiwe ngokunyathela, zizoqina. Izinsimbi ezahlukene zinamazinga ahlukene okuqina. Ngokuvamile, insimbi enamandla aphezulu e-alloy ephansi ikhuphuka kancane ngo-20MPa, ngaphansi kuka-10%. Qaphela: amandla okukhiqiza ensimbi yesigaba esiphindwe kabili akhuphuke ngo-140 MPa, ukwanda okungaphezu kuka-40%! Ngesikhathi senqubo yokwakha, insimbi izohluka ngokuphelele, ngokungafani nhlobo ngaphambi kokuba inqubo yokunyathela iqale. Amandla okukhiqiza alezi zinsimbi anda kakhulu ngemva kokucindezelwa. Ukucindezeleka okuphezulu kokukhiqiza kwezinto ezihambisana nokuqina komsebenzi kufana nokwanda okukhulu kokucindezeleka kokugeleza. Ngakho-ke, ukuqhekeka, ukubuyela emuva, ukushwabana, usayizi wezinto zokusebenza, ukuguguleka kwedayi kanye nokuguguleka kwe-micro welding kube yimbangela yezinkinga enqubweni yokwakha yensimbi enamandla aphezulu.
Ngokusekelwe ezicini nasezicini zensimbi enamandla aphezulu, uma ukugeleza kwensimbi kungenakushintshwa futhi ukungqubuzana kungenakuncishiswa, ukuqhekeka kanye nokuthungwa okungalingani kwensimbi enamandla aphezulu (i-HSS) kungaholela ekwandeni kwesilinganiso se-component scrap. Amandla aphezulu e-kilopound nge-square inch (Ksi) yale nto (iyunithi yokulinganisa amandla okukhiqiza), ukuphindaphindeka okuthuthukisiwe, ukuthambekela kokuqina komsebenzi kanye nokusebenza ekushiseni okuphezulu kokwakheka konke kuyinselele kudayi.
Ubuchwepheshe bebhodi elingenalutho elihlanganisiwe elenziwe nge-laser kanye nobuchwepheshe obuqhubekayo obuguquguqukayo obuguquguqukayo
1. Ama-Welded Blanks (Ama-Welded Blanks, TWB) asebenzisa i-laser njengomthombo wokushisa wokushisela ukuhlanganisa nokushisela izinto eziningana ezahlukene, ubukhulu obuhlukene, kanye nokwembozwa okuhlukile kwensimbi, insimbi engagqwali, i-aluminium alloy, njll. epuletini lonke.
2. Ukusebenzisa ubuchwepheshe bokushisela obuklanyelwe i-laser, kungenzeka ukuhlanganisa ngokufanele izinto ezinobukhulu obuhlukene kanye namazinga amandla ngokwezimo zokucindezeleka zezingxenye zesakhiwo, ukuthuthukisa ukuqina kwesakhiwo ngenkathi kunciphisa isisindo sezingxenye, kanye nokwandisa izinga lokusetshenziswa kwezinto futhi kuncishiswe inani lezingxenye. Inani lezingxenye kule nqubo lenza inqubo ibe lula. Ubuchwepheshe bokushisela obuklanyelwe i-laser bube yindlela eyinhloko yobuchwepheshe yokukhanya kwezimoto, futhi busetshenziswe kumamodeli abakhiqizi abaningi. Busetshenziswa kakhulu kumaphaneli angaphakathi omnyango wangaphambili nowangemuva, imisebe ende yangaphambili neyangemuva, amaphaneli aseceleni, amaphaneli aphansi, izinsika ze-A, B, kanye ne-C ngaphakathi komnyango, izembozo zamasondo kanye namaphaneli angaphakathi esiqu, njll.
3. Ama-Rolling Blanks (TRB), abizwa nangokuthi ama-differential thickness plates, abhekisela ekushintsheni kwesikhathi sangempela kosayizi we-roll gap kukhompyutha ngesikhathi senqubo yokugoqa ipuleti lensimbi, ukuze ipuleti elincane eligoqiwe libe nesiqondiso esinqunyiwe kusengaphambili eceleni kwendlela yokugoqa. Isimo se-cross-sectional esiguquguqukayo ngokwezifiso.
4. Ubuchwepheshe bephaneli eguquguqukayo eqhubekayo busetshenziswe kabanzi ekwakhiweni kwezingxenye zesakhiwo somzimba, njengesimbozo senjini, insika ye-B, ishasi yomzimba, umhlahlandlela wesikhala semoto, iphaneli yangaphakathi yekholomu ephakathi, i-mudguard kanye nebhokisi lokuphahlazeka, njll., futhi busetshenziswe ngempumelelo kumamodeli e-Audi, BMW, Volkswagen, GM nakwamanye.
5. Ubuchwepheshe bokushisela obuhambisana ne-laser kanye nobuchwepheshe bokushisela obuhambisana ne-continuous variable bushintsha ubukhulu bezinto zokunyathela ngezindlela zobuchwepheshe ezahlukene, futhi busetshenziselwa ukuxazulula inkinga yezidingo ezahlukene zamandla okuthwala umthwalo ezingxenyeni ezahlukene zezingxenye zezimoto ezingaphansi komthwalo. Uma kuqhathaniswa nalezi ezimbili, inzuzo yobuchwepheshe bokushisela be-laser obuklanyelwe wena itholakala ekuguquguqukeni kwayo, okungaqinisekisa ukushisela kwanoma yisiphi isikhundla kanye nokushisela kwezinto ezahlukene. Inzuzo yobuchwepheshe bokushisela obuhambisana ne-continuous variable ukuthi akukho mthungo wokushisela, ushintsho lobunzima ohlangothini lobude luthambile, lunokwakheka okungcono, futhi ikhwalithi yobuso ilungile, ukusebenza kahle kokukhiqiza kuphezulu, futhi izindleko ziphansi. Imithwalo, imishini yezokwelapha, igobolondo lesithuthuthu; imoto, uphahla lwangaphakathi lwebhasi, ideshibhodi; isihlalo esingemuva, iphaneli yomnyango, uhlaka lwefasitela, njll.
