Zipangizo Zamakina Aulimi - Chithunzi Chodziwika cha Pulawu Chosavala ndi Mphamvu Kwambiri

Zipangizo Zamakina Zaulimi - Plowhead Yolimba Kwambiri Yosavala

Kufotokozera Kwachidule:

Zipangizo Zosankhidwa: Kugwiritsa ntchito chitsulo chopangidwa ndi carbon low-alloy structural steel chapamwamba kwambiri kapena chitsulo chapamwamba kwambiri cha manganese cha 65Mn chokhala ndi boron, manganese, ndi zinthu zina zosakaniza. Kuwonjezera kwa zinthu zosakaniza kumapangitsa kuti zinthuzo zikhale zolimba komanso zolimba.

Kutenthetsa Kwambiri: Kudzera mu kutentha konse, kuzimitsa mafuta, ndi kutentha kwapakati, kapangidwe ka martensitic kofanana komanso kokonzedwa bwino kamapezeka. Mphepete mwapamwamba imakulitsidwanso ndi kuzimitsa kwapamwamba komwe kumachitika pafupipafupi, zomwe zimapangitsa kuti "kunja kolimba, mkati mwake mukhale wolimba": kuuma kwa pamwamba kumafika pa HRC 48-55, pomwe pakati pake pamakhala kulimba kwabwino kwambiri.

Njira Yolimbikitsira: Mitundu ina yapamwamba imagwiritsa ntchito ndodo zolumikizira zosagwirizana ndi kutopa kapena kupopera kwa plasma kuti ipange tungsten carbide hard alloy layer pamwamba pa contact, ndikupanga ukonde wolimba wosagwedezeka, womwe umawonjezera nthawi yogwira ntchito ndi nthawi 2-3 poyerekeza ndi nsonga wamba za pulawo.

Ngodya Yolowera Yosavuta: Ngodya yolowera ya 25°-30° yokonzedwa bwino kuti igwirizane ndi nthaka imapangitsa kuti izikhala yolimba, kuchepetsa kukana kugwira ntchito ndi 15%-20% komanso kuchepetsa kugwiritsa ntchito mafuta.

Kulimbitsa Nthiti ndi Kapangidwe ka Malo: Nthiti zolimbitsa za trapezoidal kumbuyo zimaletsa kupindika kwa mapindidwe pamene zinthu zambiri zikulemera; malo oyikamo mabotolo amapukutidwa bwino kuti malowo akhale olondola komanso okhazikika bwino, kupewa kumasuka ndi kusweka.

Chiyanjano Chokhazikika: Chimagwirizana ndi ISO ndi miyeso yayikulu yoyika thupi la pulawo lapakhomo, zomwe zimathandiza kuti zida zisinthe mwachangu popanda kugwiritsa ntchito zida.

Chogulitsachi chapangidwa makamaka kuti chigwiritsidwe ntchito polima ulimi wamakono. Monga chinthu chofunikira, chomwe chimawonongeka mosavuta chomwe chimakhudzana mwachindunji ndi nthaka ndipo chimapirira kukangana kwakukulu ndi kugundana, nsonga ya pulawo imapangidwa ndi chitsulo chapamwamba kwambiri. Ndi yoyenera kugwiritsidwa ntchito ndi zida zosiyanasiyana zolima monga mapulawo a moldboard, mapulawo osinthika, ndi ma ditcher, ndipo ndi gawo lothandizira kwambiri pakukweza magwiridwe antchito a makina onse, kuchepetsa kugwiritsa ntchito mphamvu, ndikuwonetsetsa kuti ulimi uli bwino.

Mosiyana ndi zinthu wamba zotayidwa, timagwiritsa ntchito njira yolondola yopangira zinthu kuti tichotse ma porosity amkati ndi mabowo amchenga, zomwe zimapangitsa kuti kukhuthala kwa zinthuzo kukhale kolimba komanso kolimba. Chitsulocho chimapangidwa mwasayansi ndi zinthu za chromium (Cr) ndi boron (B), ndipo chimatenthedwanso pamalo ofunikira. Izi zimatsimikizira kuuma kwa pamwamba pa 48-52 HRC pamene zikusunga kusinthasintha kwabwino kwa pakati, zomwe zimathandiza kuti ming'alu isagwere miyala kapena mizu ya mitengo panthawi yogwira ntchito.

Yosawonongeka kwambiri: Kudzera mu tungsten carbide coating yokhuthala kapena ukadaulo wolimba wa alloy, moyo wa ntchito m'nthaka yolimba monga mchenga ndi miyala umakulitsidwa kwambiri. Miyeso yeniyeni imasonyeza moyo wa pulawo wa nthawi 3-5 kuposa wa pulawo wamba wachitsulo.

Kulowa kwa nthaka movutikira: Kugwiritsa ntchito kapangidwe kake kozungulira, kogwirizana ndi nthaka komanso kukana kuyenda kumachepa, zomwe zimapangitsa kuti kugwiritsa ntchito mafuta mu thirakitala kuchepe ndi pafupifupi 8%-12%.

Kudzinola kotetezeka: Kapangidwe kake kapadera kamalola nsonga ya pulawo kukhala ndi m'mphepete wakuthwa panthawi yopasuka, kupewa mavuto monga kulima kosakwanira komanso kuphimba kosakwanira komwe kumachitika chifukwa cha kufooka.
