Za Mano a Chidebe

Dzino ndi chimodzi mwa zinthu zofunika kwambiri pa excavator, fosholo chidebe ndi ofanana ndi mano a anthu, komanso kuvala mbali, wapangidwa ndi dzino ndi dzino nsonga kuphatikiza dipper mano, onse ndi pini kutsinde kugwirizana.Chifukwa cha chidebe dzino avale kulephera mbali ndi dzino, bola ngati m'malo ndi nsonga.

Chifukwa cha chikoka cha mavuto azachuma, dziko lathu mwachangu azifuna zoweta, zimapangitsa msika zoweta mano chidebe anali ndi zotsatira zabwino, kupanga ambiri chidebe opanga mano zoweta msika chiyembekezo chachikulu!

A: kusanthula maganizo chidebe dzino nkhope kukhudzana ndi migodi gawo, mu wathunthu magawo osiyana ntchito m'kupita kukumba mphamvu zosiyana.Dzino gawo loyamba kukhudzana ndi zinthu pamwamba, chifukwa cha kusala kudya, chidebe dzino gawo kugunda kuchokera amphamvu.Ngati m'munsi zokolola mphamvu ya ndowa dzino, adzatulutsa pulasitiki mapindikidwe mu nsonga.Pamodzi ndi kuwonjezeka kwakuya kwa migodi, kugawa kwa mano a ndowa kudzasintha.Pamene chidebe dzino kudula zakuthupi, kuyenda wachibale zimachitika, chidebe dzino ndi zinthu kutulutsa lalikulu kwambiri extrusion kuthamanga padziko, motero chidebe dzino nkhope ndi kutulutsa mikangano yaikulu pakati pa zipangizo.Ngati zinthuzo ndi thanthwe lolimba, konkire, ndi zina zotero, mphamvu yowonongeka idzakhala yaikulu.Zotsatira za ndondomekoyi kangapo ndi pamwamba pa chidebe dzino nkhope kuchokera kutha ndi kung'ambika, motero kutulutsa kuya lalikulu mizere.Mapangidwe a dipper mano ndi zotsatira zabwino kwa kutalika kwa moyo utumiki wa dipper mano, kusankha chidebe dzino, ndithudi, kusamala chitsiru anagulitsa chidebe dzino lake ndowa dzino Inenso ntchito, zotsatira zake ndi zabwino!Nkhope pambuyo mavuto ntchito nkhope mwachionekere apamwamba kuposa kale, pamaso ntchito nkhope kwambiri avale ndi misozi, ndipo akhoza kudziwa kuthamanga zabwino ndi mikangano mphamvu yaikulu kulephera modes chidebe dzino kunja makina zinthu, amatenga mbali yaikulu mu ndondomeko zokolola.

2: kusanthula ndondomeko ya zitsanzo ziwiri kuchokera aliyense motsatana pamaso ndi pambuyo ntchito nkhope, yosalala kuuma mayeso.Kupezeka pa chitsanzo chomwecho kuuma kusiyana ndi lalikulu kwambiri, chiweruzo choyambirira ndi wosagwirizana.Zitsanzo kuti akupera, kupukuta, etching, anapeza kuti aliyense chitsanzo pa malire zoonekeratu, basi mzere mbali zosiyanasiyana.Kuchokera ku mawonedwe a macroscopic, imvi yotuwa, yozungulira gawo lapakati, ndi mtundu wakuda kwambiri imasonyeza kuti chinthu chomwe chikhoza kukhazikitsidwa, pamwamba, chizingiridwe mbalizo ziyeneranso kukhala zidutswa.Mu HRS - 150 digito rockwell hardness tester ndi MHV - 2000 digito yowonetsera microhardness mita pa mzere kumbali zonse za kuyesa kuuma, motsatana, adawonetsa kusiyana kwakukulu (onani tebulo 1).Kudzera pamwamba kusanthula anatsimikizira kuti dipper mano anapereka chidutswa cha dongosolo.Tsekani ena mwa iwo ndi chidutswa, gawo ndi matrix ozungulira iwo.The zikuchokera onse pafupi, monga Cr, Mn, Si aloyi zinthu, zinthu zazikulu aloyi (misa kachigawo,%) wa 0,38 C, 0,91 0,83 0,83 Mn, Cr, Si.The makina katundu wa zitsulo zipangizo zimadalira zikuchokera zinthu ndi ndondomeko kutentha mankhwala.Kusiyanitsa pakati pa mapangidwe ofanana ndi kuuma kwa mano a ndowa popanda kutentha kwa kutentha komwe kumagwiritsidwa ntchito pambuyo poponya.Bungwe lomwe limayang'anira zochitikazi likutsimikiziranso mfundo imeneyi.
