Imibuzo Ebuzwa Rhoqo
Yintoni umahluko phakathi kwe-SPCC kunye ne-SPCE yentsimbi yokunyathela?
I-SPCC yintsimbi epholileyo epholileyo kunye neyona nto iphezulu yekhabhoni ye-0.12%, ilungele ukugoba okulula kunye nokudonsa okunzulu. I-SPCE inomda wekhabhoni ephantsi (≤0.08%), i-manganese ephantsi (≤0.40%), kunye ne-elongation ephezulu kakhulu (≥41% vs. ≥37%), okwenza kube ngcono kakhulu kwimisebenzi enzulu yokudweba. I-SPCE nayo inexabiso eliqinisekisiweyo le-r (i-plastic strain ratio) ye-≥1.6, oku kuthetha ukuba iyaxhathisa ukubhitya ngexesha lokuzolula. Sebenzisa iSPCC kwizibiyeli kunye neendawo ezisicaba; sebenzisa i-SPCE xa inxalenye ifuna umzobo onzulu okanye onzima.
Kufuneka ndisebenzise nini intsimbi eshushu eqengqelekayo endaweni yentsimbi eqengqelekayo xa ndinyathela?
Khetha intsimbi eshushu eqengqelekayo xa inxenye ibunjwe ngendlela enento yokwenza, igeyiji ingaphezulu kwe-3.2 mm (ngaphaya kobuninzi obukhoyo obubandayo), ukunyamezelana okuqinileyo akufuneki, okanye iindleko ngumqhubi ophambili. Intsimbi eshushu eqengqelekayo ixabisa i-15-25% ngaphantsi ngetoni nganye kwaye inobude obuphezulu, obunceda ekugobeni nasekwenzeni amacandelo angqingqwa. Nangona kunjalo, umgangatho wayo wokusila ufuna ukuqhushumba okanye ukucolwa phambi kokupeyintwa, kwaye ukunyamezelwa kobungqingqwa ±0.10–0.15 mm xa kuthelekiswa ne-±0.02–0.05 mm xa kuqengqeleka ukubanda.
Ndikuthintela njani ukuqhekeka xa ndinyathela intsimbi ephezulu yokuqina okuphezulu?
Ukuqhekeka kwi-AHSS ngokuqhelekileyo kwenzeka kwi-bend radii eqinile kakhulu kwisakhono sokwandiswa kwebakala. Kwi-DP590, i-design bend radii ≥ 1× ubukhulu bezinto; kuba DP780, ≥ 1.5×; kuba DP980, ≥ 2.5×; kunye namabanga martensitic (MS1200), ≥ 5× ubukhulu. Ukugoba kwe-Orient kwi-perpendicular ukuya kwicala lokuqengqeleka, sebenzisa izithambisi zoxinzelelo oluphezulu, kwaye zithathele ingqalelo ukwenza ubushushu (200-300 °C) kwezona geometries zifuna kakhulu. Ukuqhuba ukulinganisa kwe-FEA phambi kokuba ulwakhiwo luchonge iingozi zokuqhekeka kwangoko.
Loluphi unyango lomphezulu lulungele iindawo zokutywina zentsimbi zangaphandle?
Ukuvezwa kwangaphandle kwexesha elide, i-hot-dip galvanizing (GI) ibonelela ngexabiso elifanelekileyo lokukhusela umlinganiselo kunye neeyure ze-300-1,000 zokuxhathisa ityuwa ngokuxhomekeke kubunzima bokugquma. Kwiindawo ezifuna ukugqitywa kokuhombisa, ukugquma komgubo phezu komphezulu wephosphated kuzisa ukuxhathisa okugqwesileyo kokutya (1,000+ iiyure zokutshiza ngetyuwa) ngombala kunye neendlela zokuthungwa. I-Dacromet okanye i-Geomt i-zinc-aluminium flake coatings ilungele i-fasteners kunye neendawo ezincinci apho ukufana kobunzima kunye nomngcipheko we-hydrogen-embrittlement yinkxalabo.
Yintoni ireyithi yokusetyenziswa kwezinto ezilungileyo kwi-ufa oqhubekayo steel isitampu?
Ireyithi yokusetyenziswa kwezinto eziphathekayo ye-60-75% ithathwa njengelungileyo kwi-ufa oqhubekayo isitampu yamalungu entsimbi. Amaxabiso angaphantsi kwe-55% acebisa ukuba i-party layout kufuneka ihlaziywe ukwenzela ukulungiswa kwendlwane - uphuculo oluqhelekileyo lubandakanya ukujikeleza inxalenye ye-orientation, ukwabelana ngemigca ye-trim phakathi kweendawo ezikufutshane, okanye ukuyila ngokutsha i-carrier strip geometry. Ngaphezulu kwe-75% yokusetyenziswa kuyafikeleleka kwiindawo ezilula ezixande. Nasiphi na isiqwenga se-trim kufuneka sivavanyelwe ukusetyenziswa okwesibini ukugqunywa kwamalungu amancinane ukusuka kumcu omnye.
Ukuqukumbela
Isitampu sentsimbi esiphumeleleyo siqala ngokuthelekisa ibakala kwisicelo. Insimbi ethambileyo (SPCC-SPCE) ibamba iindawo ezininzi zenjongo jikelele ngeendleko-ngempumelelo, ngelixa amabakala e-AHSS (DP, TRIP, CP, MS) ahambisa umlinganiselo wamandla-kuya-ubunzima obufunwa yi-izithuthi and industrial applications - ngeendleko zenkqubo yokulawula inkqubo kunye nezixhobo ezinzima. Ukukhetha unyango oluphezulu, ukunyamezela, kunye nemigaqo ye-DFM iqinisekisa ngakumbi ukuba inxalenye yensimbi enesitampu inikezela ukusebenza okuthembekileyo kwiindleko zokhuphiswano.
