Kumtunda kwa mbale ya nsagwada yosunthika kumalumikizidwa ndi shaft ya eccentric, kumunsi kumathandizidwa ndi thrust plate, ndipo nsagwada yokhazikika imakhazikika pa chimango. Mphepete mwa eccentric ikazungulira, mbale ya nsagwada yosunthika imakhala ndi zinthu zomwe zimatuluka, pomwe mbale ya nsagwada yokhazikika imakhala ndi kutsetsereka kwa zinthuzo. Monga gawo lokhala ndi kuchuluka kwa kusweka kwa nsagwada ndi kuvala, kusankha kwa nsagwada kumakhudzana ndi mtengo ndi phindu la ogwiritsa ntchito.
Manganese wambirichitsulo High manganese zitsulo ndi zinthu miyambo ya nsagwada crusher nsagwada mbale, ali ndi zotsatira zabwino katundu kukana, koma chifukwa cha dongosolo crusher, ndi ngodya pakati pa mphamvu ndi okhazikika nsagwada mbale ndi lalikulu kwambiri, zosavuta chifukwa abrasive kutsetsereka, chifukwa. kuti mapindikidwe kuumitsa sikokwanira kuti nsagwada mbale pamwamba kuuma ndi otsika, abrasive yochepa osiyanasiyana kudula, nsagwada mbale kuvala mofulumira. Pofuna kupititsa patsogolo moyo wautumiki wa mbale ya nsagwada, zida zosiyanasiyana za nsagwada zapangidwa, monga kuwonjezera Cr, Mo, W, Ti, V, Nb ndi zinthu zina kuti zisinthe chitsulo chachikulu cha manganese, ndi kulimbikitsa kubalalika. chithandizo cha chitsulo chachikulu cha manganese kuti chiwongolere kuuma kwake koyamba ndi kutulutsa mphamvu. Kuphatikiza apo, chitsulo chapakatikati cha manganese, chitsulo chochepa cha aloyi, chitsulo chokwera kwambiri cha chromium ndi chitsulo chachikulu cha manganese chapangidwa, ndipo zotsatira zabwino zapezeka popanga.
China Manganese Steel idapangidwa koyamba ndi Kampani ya Climax Molybdenum ndipo idalembedwa mwalamulo ku United States patent mu 1963. Njira yowumitsa ili motere: kuchepetsedwa kwa manganese, kukhazikika kwa austenite kumachepa, ndipo ikakhudzidwa kapena kuvala, austenite imakonda kusinthika-kupangitsa martensitic kusintha, komwe kumawonjezera kukana kwake kuvala. The mwachizolowezi zikuchokera manganese zitsulo (%) : 0.7-1.2C, 6-9Mn, 0.5-0.8Si, 1-2Cr ndi kufufuza zinthu V, Ti, Nb, osowa lapansi ndi zina zotero. Moyo weniweni wautumiki wa mbale yachitsulo yachitsulo ya manganese ndi yoposa 20% kuposa yachitsulo cha manganese, ndipo mtengo wake ndi wofanana ndi wachitsulo cha manganese.
03 Chitsulo chachitsulo cha chromium chapamwamba Ngakhale kuti chitsulo chapamwamba cha chromium chimakhala ndi kukana kwamphamvu kwambiri, koma chifukwa cha kulimba kwake kosalimba, kugwiritsa ntchito chitsulo chachitsulo cha chromium monga mbale ya nsagwada sizimapeza zotsatira zabwino. M'zaka zaposachedwapa, mkulu chromium kuponyedwa chitsulo kapena womangidwa kwa mkulu manganese zitsulo nsagwada mbale kupanga wachibale nsagwada mbale, wachibale kuvala kukana mpaka 3 zina, kuti moyo utumiki wa mbale nsagwada kwambiri kuchuluka. Iyi ndi njira yabwino yowonjezeramo moyo wautumiki wa mbale ya nsagwada, koma kupanga kwake kumakhala kovuta kwambiri, choncho n'kovuta kupanga.
Chitsulo cha carbon low alloy cast ndinso chogwiritsidwa ntchito kwambiri chosagwira ntchito, chifukwa cha kuuma kwake kwakukulu (≥45HRC) komanso kulimba koyenera (≥15J/cm²), kumatha kukana kudula zinthu komanso kutulutsa mobwerezabwereza chifukwa cha kutopa, kuwonetsa bwino. kuvala kukana. Pa nthawi yomweyo, sing'anga mpweya otsika aloyi kuponyedwa zitsulo angathenso kusinthidwa ndi zikuchokera ndi kutentha ndondomeko mankhwala, kuti kuuma ndi toughness akhoza kusintha osiyanasiyana lalikulu kukwaniritsa zofunika zosiyanasiyana ntchito. Mayeso ogwirira ntchito akuwonetsa kuti moyo wautumiki wa mbale yapakatikati ya carbon low alloy steel nsagwada ndi yopitilira nthawi 3 kuposa yamanganese ambirizitsulo.
Malingaliro osankha mbale ya nsagwada:
Mwachidule, kusankha zinthu nsagwada mbale bwino kukwaniritsa zofunika za kuuma mkulu ndi kulimba mkulu, koma kulimba ndi kuuma zinthu zambiri zotsutsana, kotero mu kusankha kwenikweni zipangizo, tiyenera kumvetsa bwino zinthu ntchito, wololera. kusankha zipangizo.
1) Kuchulukirachulukira ndi chimodzi mwazinthu zofunika zomwe ziyenera kuganiziridwa pakusankha kwazinthu zoyenera. Zomwe zimapangidwira, zimakhala zolemera kwambiri zomwe zimavala, zimakhala ndi lumpiness ya zipangizo zosweka, komanso katundu wambiri. Panthawiyi, chitsulo chosinthidwa kapena chobalalika chokhazikika cha manganese chingagwiritsidwe ntchito ngati chinthu chosankhidwa. Kwa ophwanyira apakati ndi ang'onoang'ono, zomwe zimakhudzidwa ndi zigawo zosavuta zogaya sizili zazikulu kwambiri, kugwiritsa ntchito chitsulo chochuluka cha manganese, n'kovuta kuti chizigwira ntchito mwakhama. Pansi pamikhalidwe yotereyi, kusankha kwa sing'anga carbon low alloy steel kapena high chromium cast iron/low alloy steel composite zakuthupi kumatha kupeza zabwino zaukadaulo ndi zachuma.
2) Kuphatikizika kwa zinthuzo ndi kuuma kwake ndizinthu zomwe sizinganyalanyazidwe pakusankha koyenera. Kawirikawiri, kuuma kwa zinthuzo kumakwera kwambiri, kumapangitsanso kuuma kwa zinthu zomwe zimakhala zosavuta kuvala, kotero pansi pa chikhalidwe chokwaniritsa zofunikira zolimba, zinthu zokhala ndi zovuta kwambiri ziyenera kusankhidwa momwe zingathere. .
3) Kusankha kwazinthu zomveka kuyeneranso kuganizira za kuvala kwa zida zovalira mosavuta. Ngati kuvala kudula ndiye chinthu chachikulu, kuuma kuyenera kuganiziridwa poyamba posankha zipangizo. Ngati kuvala kwa pulasitiki kapena kutopa ndiko kuvala kwakukulu, pulasitiki ndi kulimba ziyenera kuganiziridwa poyamba posankha zipangizo. Zoonadi, posankha zipangizo, ziyeneranso kulingalira za kulingalira kwa ndondomeko yake, zosavuta kulinganiza kupanga ndi kulamulira khalidwe.
