1.What ne karfe foda allura gyare-gyaren fasaha?
A cikin duniyarfoda karfe,Karfe foda gyare-gyare (MIM) wani nau'in fasahar gyare-gyaren gidan yanar gizo ne. Hanyoyi guda shida sun haɗa da tsarin MIM: samar da foda, haɗa shi tare da abin ɗaure, gyaran allura, ƙara kayan ragewa da cirewa, sintering da curing, da ƙarewa.
Cikakkun bayanai sune kamar haka: masana'anta na MIM suna buƙatar ƙaramin ƙaramin ƙarfe foda girman girman, gabaɗaya a cikin kewayon 0 zuwa 30 microns, ta hanyar ultra-high matsa lamba ruwa atomization ko hanyar atomization gas; Gauraye foda da ɗaure: foda na ƙarfe da mai ɗaure na halitta an gama gauraye su cikin ɓangarorin, kuma ɓangarorin cakuda suna mai zafi cikin yanayin filastik; Yin gyare-gyaren allura: ta na'urar gyare-gyaren allura don matse cakuda a cikin rami na mold, samar da sassan farko; Daure mai lalata: ta hanyar sinadarai ko hanyar bazuwar thermal don cire abin ɗaure a cikin billet ɗin sassa, don samun ƙarfe kawai ko ɗan ɗauri ragowar sassan billet; Sintering da curing: Ana aika sassan zuwa tanderun da aka yi amfani da su don magancewa don ƙara cire ragowar abin ɗaure; Bayan-jiyya: ta hanyar quenching zafi magani, sinadaran zafi magani, tururi magani da kuma sauran hanyoyin da za a rage ciki pores na sassa, inganta yawa sassa, inganta ƙarfin sassa, lalata juriya da kuma sa juriya, da dai sauransu, don samar da karshe sassa.
2, Waɗanne kayan haɗi sun dace da fasahar gyare-gyaren foda na ƙarfe?
A halin yanzu ana amfani da MIM na kasar Sin sosai a cikin kayayyaki iri-iri, da suka hada da agogo, kananan na'urorin likitanci, kayan wasanni, makamai masu sauki, da sauran kayayyaki. Fasahar MIM, wacce tana ɗaya daga cikin ingantattun fasahohin da suka dace da injinan gargajiya, na iya amfani da kayan aiki da yin samfura masu sarƙaƙƙiya da tsari fiye da injinan gargajiya.
Ana iya rarraba aikin da ya dace da fasahar MIM zuwa yanayi masu zuwa:
1, a cikin tsarin yankan gargajiya ko tsarin nika, asarar kayan abu yana da girma sosai, kuma lokacin aiki yana da tsayin daka, wanda ya dace da fasahar MIM don rage farashin.
2, MIM na iya zama samar da taro, saduwa da wasu yanayi na samar da taro, amma buƙatun yana da ƙasa fiye da farashin kayan buɗewar mold wanda ya dace da fasahar MIM.
3. Don karafa da ke da wuya a yanke, irin su titanium da nickel alloy, ana iya la'akari da fasahar MIM don masana'antu. Za a inganta madaidaicin samfurori idan aka kwatanta da aikin gargajiya, kuma kayan za su sami ceto sosai.
4, tare da hadaddun siffar geometric, irin su zaren surface, klooping, giciye nassi da sauran sassa, irin wannan sassa a cikin gargajiya foda metallurgy ne da wuya a cimma, a cikin yankan tsari bukatar canja wurin aiki tashar na Multi-axis sassa ko Multi-reference sassa, dace da MIM fasahar sarrafa.
5. Sassan da ake buƙatar sarrafa su ta hanyar haɗakar abubuwa daban-daban, kamar sassan da aka sarrafa ta hanyar haɗin ƙarfe da kayan yumbura, ko sassa da aka sanya su da kayan daban-daban, irin su magnetic hard - magnetic soft, Magnetic - non-magnetic, conductive - insulating kayan.
3, Menene kayan da suka dace da fasaha na fasaha na foda foda?
Fasahar MIM tana amfani da kayan aiki da yawa. A ka'ida, idan dai wurin narkewa ya kasance sama da zafin jiki, ana iya yin kayan foda ta hanyar fasahar MIM. Idan akai la'akari da tattalin arziki, a halin yanzu da aka fi amfani da kayan, yafi hada da baƙin ƙarfe tushe, nickel tushe, low gami, wuya gami, da dai sauransu JIEHUANG CHIYANG kamar yaddaMIM sassa masana'antayayi ferrous da nickel na tushen gami karfe foda kayan for karfe foda gyare-gyaren gyare-gyare, tare da kayan aiki Manuniya kai masana'antu ta ci-gaba matakin.
