Zipangizo zamakina a ulimi, fosholo ya tiller, 65Mn forging

Kufotokozera Kwachidule:

Tsamba la pulawo, lomwe ndi gawo lothandizira pamakina a ulimi, ndi gawo lofunika kwambiri logwiritsidwa ntchito pa pulawo, nthawi zambiri limapangidwa ndi chitsulo cha manganese kapena boron chomwe chimazimitsidwa ndi kupangidwa. Ntchito zake zazikulu ndikudula nthaka, kukweza zipolopolo, ndikuswa zipolopolo za nthaka. Nsonga yakuthwa ya tsamba imachepetsa bwino kukana kulima, ndipo kapangidwe ka tsamba losatha kutha ntchito kamawonjezera nthawi yake yogwira ntchito. Ndi yoyenera kulima m'malo ouma ndipo imatha kusintha kwambiri magwiridwe antchito komanso ubwino wa kulima.

Ma tag a Zamalonda

Mapeyala ndi zida zamakina a ulimi olondola kwambiri komanso osawonongeka omwe adapangidwira makamaka ulimi wamakono. Ndi oyenera mapeyala akuluakulu, apakatikati, ndi ang'onoang'ono komanso mapeyala osinthika. Monga gawo lofunikira kwambiri lokhudzana ndi nthaka lomwe limakhudza mwachindunji nthaka, limazindikira mwachindunji kuzama kwa ulimi, momwe nthaka imasinthira, komanso momwe thirakitala imagwiritsira ntchito mafuta ochepa. Timagwiritsa ntchito chitsulo chapamwamba kwambiri cha manganese kapena chitsulo cha masika cha 65Mn, chophatikizidwa ndi njira zolondola zopangira ndi kutentha, kuti tiwonetsetse kuti tsamba lililonse la pulawo lili ndi kuuma kwakukulu, kukana kuwonongeka bwino, komanso kulimba bwino, zomwe zimapangitsa kuti likhale chisankho chabwino kwambiri chogwirira ntchito yolima mozama komanso yobwezeretsa udzu.

Chitsulo cha aloyi cha manganese chokhala ndi ma ratios apadera chimalimba mofulumira pamwamba pa kugunda kwakukulu kapena kupsinjika kwakukulu, ndikupanga gawo lolimba kwambiri losawonongeka, pomwe mkati mwake mumakhalabe wolimba kwambiri. Khalidwe la "lolimba kunja ndi lolimba mkati" limawonjezera moyo wolimba wa mapulawu ndi mafosholo ndi 30% -50% poyerekeza ndi zinthu wamba zomwe zimagwiritsidwa ntchito movutikira monga mchenga ndi miyala ndi nthaka yopapatiza, zomwe zimachepetsa nthawi yogwira ntchito yosinthira zida pafupipafupi.

Ngodya yolowera m'nthaka ndi nsonga ya fosholo ya fosholo ya pulawo zakonzedwa bwino kudzera mu kusanthula kwa CAE finite element, ndipo zili ndi luso labwino kwambiri lolowera m'nthaka. Nsonga yakuthwa ya fosholo imatha kudula mosavuta mu gawo lopapatiza, sikuti imangokhala ndi mphamvu yabwino yophwanya nthaka komanso kukana kulima, komanso imachepetsa kwambiri mphamvu yokoka ya thirakitala. Mphamvu yoyezedwa yosunga mafuta ikhoza kufika 5% -8%, kukuthandizani kuchepetsa bwino ndalama zogwirira ntchito polima kwakukulu.

Kapangidwe ka chinthucho kali ndi kapangidwe kapadera ka tsamba lodzipukutira lokha. Pa ntchito yophunzira kunyumba, ziwalo za pulawo ndi fosholo zomwe zimagundana ndi nthaka zidzapitirira kuwonongeka, koma chifukwa cha kusiyana kwa kuchuluka kwa zinthu ndi kuuma pakati pa ziwalo zakutsogolo ndi zakumbuyo, pulawo ndi fosholo zimatha kukhala ndi m'mphepete wakuthwa nthawi zonse pogwira ntchito, kupewa vuto la "tsamba losamveka" ndikuwonetsetsa kuti nthaka ikuzama bwino komanso kuti nthaka ikuzunguliridwa bwino.

Kutsatira miyezo ya dziko (kapena miyezo ya ISO) mosamalitsa popanga, ndi malo okhazikika a mabowo, oyenera ma plaw body ambiri omwe ali pamsika. Musanachoke ku fakitale, kuyang'anitsitsa bwino khalidwe kumachitika kuti muwonetsetse kuti palibe mabowo osweka kapena ma burrs. Zigawo zoyambirira zitha kusinthidwa mwachindunji, zomwe zimapangitsa kuti zikhazikike nthawi yomweyo ndikugwiritsa ntchito popanda kufunikira kukonza kwina.
