Malo Ophikira/Kusefa kwa Makina a Pafamu/Kusefa kwa Mlimi/Fosholo ya Mlimi Yooneka ngati Muvi

Kufotokozera Kwachidule:

Fosholo iyi yokhala ndi mapiko awiri yokhala ndi mivi ndi chinthu chofunikira kwambiri cholimira makina a ulimi,

Chopangidwa mwapadera kuti chizisamalira mbewu za m'munda. Thupi lalikulu limapangidwa ndi mphamvu zambiri

Chitsulo chosatha ntchito monga chitsulo cha 65Mn, cholimba chifukwa cha kutentha ndi kuzimitsidwa, cholimba kwambiri,

kukana kwamphamvu kwa kuvala, kukana kukhudzidwa ndi kukana kupindika, komwe kumatha kusintha kuti kugwirizane ndi gawo lamphamvu kwambiri

ntchito. Pamwamba pake pamatiridwa ndi utoto wabuluu woletsa dzimbiri kuti pakhale nthawi yayitali yogwirira ntchito.

Zipangizo zothandizira za makina a ulimi, monga mapulawu ndi mafosholo, zimapangidwa ndi chitsulo champhamvu komanso chosatha. Mphepete mwa makinawa yakhala ikutenthedwa mwapadera, zomwe zimapangitsa kuti ikhale yakuthwa komanso yolimba, komanso yolimba kwambiri kuti isalowe m'nthaka. Yoyenera kulima mozama pansi pa nthaka zosiyanasiyana, zomwe zimapangitsa kuti nthaka isamasweke bwino komanso kuzunguliridwa bwino. Kapangidwe kake ka mabowo oyika kamagwirizana ndi mitundu yayikulu ya pulawu ndipo ndi kosavuta kusintha. Yolimba ku kugwedezeka ndi kupindika, imatha kukulitsa moyo wonse wa zigawo za ulimi ndipo ndi chisankho chabwino kwambiri pa ntchito zaulimi zogwira mtima.

Chogulitsachi chimapangidwa ndi zinthu ziwiri zapamwamba kwambiri za alloy, chitsulo cha manganese cha 65Mn ndi chitsulo cha boron cha 30MnB, zomwe zimapangidwa ndi forging yophatikizana yotentha 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.

Kukana kuvala kwambiri: Nthawi yogwira ntchito ndi yayitali nthawi 2-3 kuposa mafosholo wamba, ndipo imatha kugwira ntchito mosalekeza kwa maekala 800-1200 pansi pa mikhalidwe yabwinobwino ya loam.

Kukana kugwedezeka: Mukakumana ndi zopinga monga miyala ndi mizu ya mitengo, matrix yolimba imatha kupirira bwino ndipo siisweka mosavuta

Kudzinola: Kapangidwe kake kapadera ka multilayer composite kamasunga tsamba lakuthwa panthawi yogwiritsidwa ntchito.

Kuletsa kuchotsedwa kwa nthaka: Pamwamba pake pamapukutidwa kuti pakhale kuchuluka kwa kuchotsedwa kwa dothi ndi 30%, zomwe zimapangitsa kuti pakhale koyenera kugwiritsidwa ntchito kwambiri panthaka.
