Isitsha Esishisayo Samanzi Ethangi Elijingiwe Elisetshenziselwe I-Steel Boiler Plate A516-70
I-Q460 iyinsimbi ene-alloy ephezulu enamandla amakhulu. Indlela yokuqoka ye-Q460: inombolo yayo yensimbi iqalwe ngokuthi "Q", emele iphuzu lokukhiqiza lensimbi, okungukuthi, amandla okukhiqiza. Inombolo elandelayo ibonisa ukuthi inani lephuzu lesivuno elingu-460 limelela i-460 MPa, i-mega ingamandla angu-6 we-10, futhi i-Pa iyunithi yokucindezela uPascal. I-Q460 isho ukuthi ukuguqulwa kwepulasitiki yensimbi kuzokwenzeka kuphela lapho amandla ensimbi efinyelela ku-460 MPa, okungukuthi, lapho kukhululwa amandla angaphandle, insimbi ingakwazi ukugcina isimo esigcizelelwe kuphela futhi ayikwazi ukubuyela esimweni sayo sokuqala. Lawa mandla makhulu kunawensimbi evamile. Izimpawu zebanga ezijwayelekile ziyi-A, B, C, D, E, ngokulandelana. Ngokwesisekelo sokuqinisekisa ukulingana kwekhabhoni ephansi, i-Q460 inyusa ngokufanelekile okuqukethwe kwezakhi ze-microalloying. Ukusebenza kahle kokushisela kudinga okulingana nekhabhoni ephansi yensimbi, futhi ukwanda kwezakhi ze-microalloying kukhulisa amandla ensimbi ngenkathi kukhulisa okulingana nekhabhoni yensimbi. Kodwa ngenhlanhla, i-carbon equivalent eyengeziwe incane, ngakho-ke ngeke ithinte ukusebenza kwe-welding yensimbi.
Intuthuko esheshayo yemboni yezimoto ibambe iqhaza elibalulekile ekuthuthukisweni komnotho nenhlalakahle kazwelonke. Kodwa-ke, ngenxa yomthelela wokuntuleka kwamandla, ukungcoliswa kwemvelo kanye nezinye izinkinga, ukuphikisana ekuthuthukisweni kwemboni kuye kwavela kakhulu. Uma sibheke phambili ekusaseni, ukuthuthukiswa kwemboni kungasimama kuphela uma kusekelwe emlandweni wemvelo, i-ecology, ukongiwa kwamandla kanye nokuphepha.
Ngaphansi kwalesi sizinda, ukusetshenziswa kwe-automobile lightweight kanye nensimbi enamandla amakhulu sekuphenduke isiqondiso esibalulekile sokuthuthukiswa. Kodwa-ke, ngokuthuthukiswa kwamandla epuleti lensimbi lamandla aphezulu, inqubo yokugxiviza ebandayo yendabuko ijwayele ukuphuka enqubweni yokwakha, engakwazi ukuhlangabezana nezidingo zokucubungula zepuleti lensimbi lamandla aphezulu. Kulokhu, ubuchwepheshe bokwenza isitembu esishisayo sepuleti yensimbi ye-ultra-high iye yafundwa kancane kancane emhlabeni - inqubo entsha ehlanganisa ukwakha, ukudluliswa kokushisa kanye nokuguqulwa kwe-microstructure, okusetshenziselwa ikakhulukazi izici ze-plasticity anda nokunciphisa isivuno amandla eshidi. metal esimweni sokushisa okuphezulu kwe-austenite. Kodwa-ke, i-thermoforming idinga ucwaningo olunzulu ngezimo zenqubo, ukuguqulwa kwesigaba sensimbi kanye nobuchwepheshe bokuhlaziya i-CAE, kodwa lobu buchwepheshe buphethwe abakhiqizi bangaphandle futhi bukhula kancane kancane e-China.
Ngokusho kocwaningo kanye nezibalo, ukusetshenziswa kwensimbi enamandla kakhulu kwezinye izinhlobo zezimoto kuyakhula, futhi ukusetshenziswa kwensimbi ephezulu yohlaka lomzimba kwamanye amamodeli sekufinyelele ku-90%. Ngokocwaningo lomnyango wamandla we-American Iron and Steel Institute, ngisho noma inani lensimbi enamandla kakhulu lincishisiwe, ukungezwani kwalo kunzima kakhulu kunepuleti elibandayo elivamile. I-ductility yensimbi enamandla amakhulu iyingxenye kuphela yensimbi evamile.
Lapho izinto zakhiwe ngokugxiviza, zizoqina. Izinsimbi ezihlukene zineziqu ezihlukene zokuqina. Ngokuvamile, amandla aphezulu aphansi ensimbi ye-alloy akhuphuka kancane kuphela ngama-20MPa, ngaphansi kuka-10%. Qaphela: amandla okukhiqiza ensimbi yesigaba esikabili akhuphuke ngo-140 MPa, ukwanda okungaphezu kuka-40%! Phakathi nenqubo yokwakha, insimbi izohluka ngokuphelele, ihluke ngokuphelele ngaphambi kokuba inqubo yokugxiviza iqale. Amandla okukhiqiza alezi zinsimbi akhuphuka kakhulu ngemva kokucindezelwa. Ukucindezelwa kwesivuno okuphezulu kwezinto ezihambisana nokuqina komsebenzi kufana nokwanda okuphawulekayo kokucindezeleka kokugeleza. Ngakho-ke, ukuqhekeka, i-springback, ukushwabana, usayizi we-workpiece, i-die wear kanye ne-micro welding wear sekugxilwe ezinkingeni ekubunjweni kwensimbi ephezulu.
Ngokusekelwe ezicini nasezicini zensimbi yamandla aphezulu, uma ukugeleza kwensimbi kungenakuguqulwa futhi ukungqubuzana akukwazi ukuncishiswa, ukuthungwa okuqhekekile nokungalingani kwensimbi yamandla aphezulu (HSS) kungase kuholele ekwandeni kwezinga le-scrap yengxenye. Amandla ekhilokhilogremu aphezulu ngeyintshi ngayinye yesikwele (i-Ksi) yale nto (iyunithi yokulinganisa amandla esivuno), ukubopha kabusha okuthuthukisiwe, ukuthambekela kokuqina komsebenzi kanye nokusebenza kumazinga okushisa okwakha aphakeme zonke izinselele zefa.
Ubuchwepheshe bebhodi lebhodi le-laser elithungayo elingenalutho neliqhubekayo eliguquguqukayo lesiphambano
1. I-Tailor Welded Blanks (i-Tailor Welded Blanks, i-TWB) isebenzisa i-laser njengomthombo wokushisa wokushisela ukuze ihlanganise futhi ishisele izinto ezihlukahlukene ezihlukahlukene, ugqinsi oluhlukene, nezindwangu ezihlukene zensimbi, insimbi engagqwali, ingxubevange ye-aluminium, njll. ibe yipuleti lonke.
2. Ngokusebenzisa ubuchwepheshe bokushisela obulungiselelwe nge-laser, kungenzeka ukuhlanganisa ngokunengqondo izinto zobukhulu obuhlukahlukene obuhlukahlukene kanye namazinga wamandla ngokuya ngezimo zokucindezeleka zezingxenye zesakhiwo, uthuthukise ukuqina kwesakhiwo ngenkathi unciphisa isisindo sezingxenye, futhi wandise izinga lokusebenzisa. wezinto zokwakha futhi unciphise inani lezingxenye. Inombolo yezingxenye ku-yenza inqubo ibe lula. Ubuchwepheshe bokushisela owenziwe nge-laser buye baba yindlela yobuchwepheshe eyinhloko yemoto engasindi, futhi isetshenziswe kumamodeli abakhiqizi abaningi. Ikakhulukazi esetshenziswa ngaphambili nangemuva amaphaneli angaphakathi komnyango, imishayo yobude bangaphambili nangemuva, amaphaneli aseceleni, amaphaneli aphansi, izinsika A, B, no-C ngaphakathi komnyango, amakhava amasondo namaphaneli angaphakathi esiqu, njll.
3. I-Tailor Rolling Blanks (TRB), ebizwa nangokuthi amapuleti okuqina okuhlukile, ibhekisela ekushintsheni kwesikhathi sangempela kosayizi wegebe le-roll ngekhompyutha phakathi nenqubo yokugingqika yepuleti lensimbi, ukuze ipuleti eligoqiwe elizacile libe nokunqunywa kusengaphambili. isiqondiso eduze nesiqondiso sokugoqa. Umumo wesiphambano esiguquguqukayo ngokwezifiso.
4. Ubuchwepheshe obuqhubekayo bephaneli yesiphambano esiguquguqukayo busetshenziswe kabanzi ekwenzeni izingxenye zesakhiwo somzimba, njengesembozo senjini, insika engu-B, i-chassis yomzimba, umhlahlandlela we-motor spacer, iphaneli yangaphakathi yekholomu ephakathi, i-mudguard nebhokisi lokuphahlazeka, njll., futhi isetshenziswe ngempumelelo kwa-Audi, BMW, Volkswagen, GM nezinye izinhlobo.
5. I-laser yokushisela i-laser kanye nobuchwepheshe obuguquguqukayo obuguquguqukayo obuqhubekayo bushintsha ukushuba kwezinto zokugxiviza ngezindlela ezahlukene zobuchwepheshe, futhi zisetshenziselwa ukuxazulula inkinga yezidingo ezahlukene zomthwalo othwala imithwalo yezingxenye ezahlukene zezingxenye zezimoto ezingaphansi komthwalo. Uma kuqhathaniswa nalokhu okubili, inzuzo yobuchwepheshe be-laser welding eyenziwe ngomsiki isekuguquguqukeni kwayo, okukwazi ukubona ukuhlanganisa kwanoma yisiphi isikhundla kanye nokuhlanganisa izinto ezahlukene. Inzuzo yobuchwepheshe obuguquguqukayo obuqhubekayo be-cross-section ukuthi awukho umthungo wokushisela, ukushintshwa kokuqina eduze kwesiqondiso sobude kuthambile, kunokwakheka okungcono, nekhwalithi yangaphezulu yinhle, ukusebenza kahle kokukhiqiza kuphezulu, futhi izindleko phansi. Imithwalo, imishini yezokwelapha, igobolondo lesithuthuthu; imoto, uphahla lwangaphakathi lwebhasi, ideshibhodi; ukusekelwa kwesihlalo, iphaneli yomnyango, ifreyimu yefasitela, njll.
