Chisel Cholimba Chopangira Mpweya wa Ulimi Chokhala ndi Zigawo Zothandizira pa Ulimi Wolemera Chithunzi Chowonetsedwa

Zida Zopangira Plow Tip Carbide Zolimba Zopangira Plow Point Zothandizira pa Ulimi Wolemera

Kufotokozera Kwachidule:

Nsonga ya pulawo, yomwe ndi gawo lothandizira pa makina a ulimi, imapangidwa ndi chitsulo champhamvu kwambiri, chosatha kutha ndipo kuuma kwake ndi kulimba kwake zimakulitsidwa kudzera mu kutentha. Kapangidwe kake kakuthwa kamachepetsa kukana kulowa m'nthaka, kudula mosavuta m'nthaka yopapatiza. Malo ofunikira amakulitsidwa ndikulimbitsidwa kuti asagwere komanso asagwere, zomwe zimawonjezera nthawi yake yogwira ntchito. Ndi yoyenera mitundu yosiyanasiyana ya pulawo yosinthika ndi pulawo ya moldboard, ndipo kuichotsa mosavuta ndikusintha kumachepetsa ndalama zolimira komanso nthawi yopuma.

Chogulitsachi ndi gawo lofunika kwambiri pa makina olima ulimi—nsonga ya pulawo—yoyenera kugwiritsa ntchito mapulawo osiyanasiyana a bolodi, mapulawo osinthika, ndi mapulawo a nthaka yapansi panthaka. Monga gawo lomwe limakhudza nthaka koyamba ndipo limakhala ndi kukangana kwakukulu ndi kukhudza, ubwino wake umatsimikizira mwachindunji kukana kwa kulima, kugwiritsa ntchito bwino mafuta, komanso kukhazikika kwa kuya kwa ntchito. Nsonga ya pulawo iyi imagwiritsa ntchito kapangidwe ka "high-strength matrix + gradient hard alloy," zomwe zimapangitsa kuti nthaka ilowe bwino, kukana kuwonongeka ndi kukwera, komanso kulimba kwa kugwedezeka. Izi zimakulitsa kwambiri nthawi yosinthira ndikuchepetsa mtengo wogwirira ntchito pa ekala iliyonse.

Matrix: Yopangidwa ndi chitsulo champhamvu cha 30MnB kapena 40Cr, chopangidwa ndi kutentha kwambiri, chokhala ndi kukhuthala kwakukulu komanso chopanda ma porosity amkati. Pambuyo popangira, imachizidwa ndi kutenthedwa kuti ipeze kapangidwe ka martensitic kofewa. Kulimba kwa matrix impact ndi ≥50J/cm², komwe kumatha kuyamwa bwino kugunda kwanthawi kochepa kuchokera ku miyala ndi mizu ya mitengo, kuchotsa chiopsezo cha kusweka kapena kusweka.

Chosatha kutha: Kuthira plasma kapena kuphimba laser kumagwiritsidwa ntchito pamwamba pa nthaka ya nsonga ya pulawo (dera lomwe latha kutha la m'mphepete mwa kutsogolo ndi pamwamba) kuti likhale ndi chitsulo chapamwamba cha chromium kapena tungsten carbide-reinforced iron-based alloy. Chophimbacho chimatha kufika pa kuuma kwa HRC 58-62, ndi makulidwe a 2.5-4.0 mm, kupanga mgwirizano wachitsulo ndi substrate ndikuchotsa chiopsezo chotha kusweka. Pansi pa kuwonongeka kwamphamvu kwambiri m'nthaka, tinthu tolimba timapanga mawonekedwe odziteteza okha "othandizira pang'ono", kuchepetsa kuchuluka kwa kutha kwa chitsulo kufika pa 1/3 yokha ya mbale zachitsulo za 65Mn wamba.

Kapangidwe ka Geometric: Malo opindika a nsonga ya pulawo amakonzedwa bwino kutengera njira yoyenda bwino ya dothi, zomwe zimachepetsa ngodya yokangana ndi nthaka. Gawo lakutsogolo lili ndi kapangidwe kopapatiza pang'onopang'ono, kopyapyala, kochepetsa kupsinjika kwa nthaka; magawo apakati ndi akumbuyo amakhuthala pang'onopang'ono kuti atsimikizire kulimba konse. Ngodya yolowera yasinthidwa kuti igwirizane ndi mitundu yosiyanasiyana ya nthaka (mchenga, dongo, dothi lotayirira), kuphatikiza kuthekera kolowera bwino komanso kukana kugwedezeka.

Kukana Kwambiri Kuvala: Mayeso a rabara wouma wa mchenga wouma m'ma laboratories akuwonetsa kuti kuchuluka kwa kuvala kwa yunifolomu ndi ≤0.25g/kg·m. Pansi pa nthaka ya mchenga wapakatikati, nsonga imodzi ya pulawo imatha kugwira ntchito yokwana maekala 500-800, ndipo moyo wake umakhala wowirikiza nthawi 2.5-3 kuposa nsonga wamba wa pulawo wachitsulo wa 65Mn.

Makhalidwe Odzinola: Chophimba cholimba cha weld ndi substrate yofewa zimapanga kuwonongeka kwa mgwirizano—substrate imawonongeka mofulumira pang'ono, zomwe zimapangitsa kuti tinthu ta carbide tomwe timapangidwa ndi simenti tizituluka pang'ono kuchokera pamalo ogwirira ntchito, nthawi zonse timakhala ndi mawonekedwe akuthwa komanso kupewa kugwiritsa ntchito mafuta ambiri chifukwa cha kufooka.

Kukana ndi chitetezo cha mphamvu: Mukakumana ndi miyala yobisika kapena zopinga zolimba, matrix yonse sidzasweka mosavuta, ndipo kusintha kwa malo kokha kungachitike; malire a pulasitiki ndi okwanira kupewa zinyalala kugwa m'munda ndikuwononga zida zina.
