Nsonga ya pulawo yozimitsidwa ndi chitsulo cha manganese, zowonjezera za thirakitala zogwira m'manja, fosholo yolima yosatha ntchito yolima
Nsonga ya pulawo, monga gawo lofunika kwambiri pa makina olima ulimi, yapangidwa makamaka kuti igwiritsidwe ntchito pa zosowa zamakono za nthaka yothamanga kwambiri, yomasuka kwambiri, komanso yovuta. Imayikidwa patsogolo pa pulawo, pulawo yozungulira, kapena pulawo yozama, ndipo ndiyo gawo loyamba lofunikira kwambiri polowera, kuswa, ndi kuphwanya nthaka. Mwa kudula ndi kung'amba nthaka bwino, kukana kwa thupi lalikulu la pulawo kumachepa kwambiri, ndipo makoma otsatira a pulawo, mbale zam'mbali za pulawo, ndi zina zimatetezedwa, zomwe zimapangitsa kuti ulimi ugwire bwino ntchito komanso kuti uzigwiritsa ntchito mphamvu zambiri.
1、Zinthu zosatha kutha: Pogwiritsa ntchito chitsulo cha manganese kapena boron steel integrated forging/casting, pambuyo pa njira zambiri zotenthetsera kutentha, kuuma kwa pamwamba kumatha kufika 45-55 HRC. Pokhala ndi zinthu za alloy monga chromium ndi molybdenum, imasunga kutha kwatha kwatha m'malo ovuta monga mchenga ndi miyala, ndipo nthawi yake yogwira ntchito ndi yayitali nthawi 2-3 kuposa momwe imagwiritsidwira ntchito ndi nsonga wamba za pulawo la carbon steel.
2、Kapangidwe ka tsamba lodzinola lokha: Kapangidwe ka tsamba lapadera lokhala ndi zigawo kapena lolumikizidwa limalola nsonga ya pulawo kukhala yakuthwa panthawi yolima, kusunga kukana kochepa polowa m'nthaka, kuchepetsa kwambiri mphamvu yogwira thirakitala, ndikusunga mafuta ndi 10% -15%.
3、Kukana kwabwino kwambiri kugwedezeka: Chipangizochi chili ndi kukana kwakukulu kugwedezeka motsutsana ndi zopinga zobisika monga miyala ndi mizu ya mitengo, ndipo sichisweka kapena kudulidwa mosavuta. Malo osalala omwe amakonzedwa bwino kudzera mu kusanthula kwa zinthu zochepa amateteza bwino katundu ndikuteteza chitetezo cha thupi la pulawo.
4、Kusintha molondola komanso kusintha mwachangu: Yopangidwa mwaluso yokhala ndi mabowo oyika ndi malo oikira zinthu motsatira miyezo ya ISO ndi mafakitale, yoyenera ma pulawo wamba am'nyumba ndi akunja (monga Reken, Gran, Kuhn, ndi zina zotero). Bolt imakhazikika kapena imagwedezeka pakapangidwe kake kosintha mwachangu, kusintha kwa munda kumatenga mphindi zochepa zokha, zomwe zimachepetsa kwambiri nthawi yogwira ntchito.
5、Kusinthasintha kwa nthaka: kupereka mawonekedwe osiyanasiyana monga owongoka, osakhwima, ooneka ngati muvi, odulidwa, ndi zina zotero, mogwirizana ndi mikhalidwe yosiyanasiyana yogwirira ntchito monga dothi lopepuka la loam, dothi lolemera lokhala ndi ming'alu, malo otayirira a miyala, ndi zina zotero. Ogwiritsa ntchito amatha kusankha mosavuta kutengera mtundu wa dothi ndi zotsalira kuti akwaniritse bwino ntchito yawo.
Pambuyo poyika nsonga iyi ya pulawu, kukhazikika kwa kuya kwa kulima nthawi zonse, pansi pa ngalande yosalala, komanso kudula bwino ziputu zitha kuchitika. Sikuti imangochepetsa kuchuluka kwa kupukutira ndi kukonza tsiku ndi tsiku, komanso imabweretsa phindu lalikulu ku minda yayikulu ndi makampani opanga makina a ulimi pochepetsa kugwiritsa ntchito mafuta ndikuwonjezera nthawi ya mapulawu. Ndi yabwino kwambiri m'malo ouma, malo obweza udzu, komanso kumanga minda yapamwamba, ndipo ndi chisankho chabwino kwambiri cholima kulima kwamakono.
