Fosholo Yopukutira Chitsulo ya 30MnB5, Fosholo Yopukutira Chitsulo ya mapiko awiri, Chomangira Chomangira Chithunzi Chodziwika

Fosholo Yopukutira Chitsulo ya 30MnB5, Fosholo Yopukutira Chitsulo ya mapiko awiri, Chomangira Cholimira

Kufotokozera Kwachidule:

Kugwiritsa ntchito kapangidwe kakale ka mapiko awiri okhala ndi muvi wooneka ngati V,

Mutu wa fosholo ndi wakuthwa, ndipo nthaka siingathe kulowa bwino,

palibe kutsekeka kwa udzu komanso palibe kumatirira matope panthawi yogwira ntchito.

Pamwamba pake pali mabowo omangira ang'onoang'ono, omwe amatha kukhala olimba

choyikidwa pa chogwirira cha fosholo cha alimi, obzala mbewu, obzala pansi pa nthaka ndi

makina ena a zaulimi, okhala ndi kuthekera kosinthasintha.

Ntchito Yaikulu: Imagwiritsidwa ntchito polima pakati pa mizere ndi kumasula nthaka ya mbewu.

Popanda kuwononga mizu ya mbewu kapena kutembenuza nthaka, imamasula nthaka yopapatiza,

kumathandizira kuti nthaka ilowe mpweya komanso kuti madzi alowe bwino, kumathandizira kusunga madzi ndi chinyezi.

mphamvu yosungira, ndipo imalimbikitsa kukula kwa mizu ya mbewu.

Chogulitsachi chimapangidwa ndi zinthu ziwiri zapamwamba kwambiri za alloy, chitsulo cha manganese cha 65Mn ndi chitsulo cha boron cha 30MnB, zomwe zimapangidwa ndi forging yokhazikika yotenthetsera kwambiri. Kapangidwe kake ndi kokhuthala ndipo kalibe zolakwika monga ma pores ndi mabowo amchenga. Pogwiritsa ntchito njira yochepetsera kutentha kwa isothermal, kuuma kwa nsonga ya fosholo kumafika pa 48-52HRC, ndipo kulimba kwa matrix kumakhalabe pamwamba pa 35-40J/cm², zomwe zimapangitsa kuti pakhale magwiridwe antchito abwino kwambiri a "kuuma kwakunja ndi kulimba kwamkati". Mphepete mwapamwamba yathandizidwa ndi chithandizo champhamvu chapafupipafupi, chokhala ndi kuuma kwa 55HRC komanso kukana kutopa kwambiri.

Fosholo ya pulawo imagwiritsa ntchito kapangidwe ka pamwamba kopindika bwino, ndipo ngodya yolowera imawerengedwa molondola (yosinthika kuyambira 22 ° mpaka 28 °), kuchepetsa bwino kukana kukoka ndi pafupifupi 15% -20%. Nsonga ya fosholo ndi khoma la fosholo zimalumikizidwa pang'onopang'ono kuti zithetse malo opsinjika. Zili ndi mabowo awiri oletsa kumasula monga muyezo, zomwe zimagwiritsidwa ntchito limodzi ndi mtedza wodzitsekera kuti zitsimikizire kuti zikugwira ntchito kwa nthawi yayitali popanda kumasula. Mitundu ina imasunga malo olumikizirana a nsonga ya fosholo, ndipo zigawo zakutsogolo zokha ndizofunika kusinthidwa nsonga ya fosholo ikatha, zomwe zimachepetsa ndalama zokonzera.
