Masamba olima okonzedwa ndi kutentha a 60Si2Mn, masamba ouma olemera, masamba ozungulira olima ochotsera dothi lolimba ndi mapiri ouma, zowonjezera pamakina a ulimi.

Masamba olima okonzedwa ndi kutentha a 60Si2Mn, masamba ouma olemera, masamba ozungulira olima ochotsera nthaka yolimba ndi mapiri ouma, zowonjezera pamakina a ulimi.

Kufotokozera Kwachidule:

Tsamba lotila limapangidwa ndi chitsulo chosatha, chokhala ndi m'mphepete wothira kutentha kuti likhale lamphamvu. Ndi loyenera kulima koyamba malo ouma, nthaka yolimba, ndi nthaka yolimba. Kapangidwe kake kapadera kofanana ndi arc kapena chisel kamaswa bwino mabulundu a nthaka ndi mizu ya udzu, kuchepetsa kukoka ndi kugwiritsa ntchito mafuta. Limagwirizana ndi ma rotary tillers ndi makina osiyanasiyana otila, ndi losavuta kuyika ndipo limathandiza kwambiri kuswa nthaka komanso kugwira ntchito bwino, zomwe zimapangitsa kuti likhale chowonjezera cholimba pokonza malo a ulimi.

Chogulitsachi ndi tsamba lamphamvu kwambiri lolima (lomwe limadziwikanso kuti tsamba lochotsera nthaka) lopangidwira makamaka ulimi. Monga chowonjezera chachikulu cha ma rotary tillers ndi mathirakitala, chimagwiritsidwa ntchito makamaka pokonzanso minda, kukonzanso malo ouma, kudula udzu, ndi kukonza ming'alu. Chapangidwa makamaka kuti chithane ndi malo ovuta komanso olimba a nthaka, zomwe zimapangitsa kuti chikhale chisankho chabwino kwambiri chowongolera kapangidwe ka nthaka ndikuwonjezera magwiridwe antchito a kulima.

Chogulitsachi chimaphatikizapo mfundo za makina ndi geometry mu kapangidwe kake, makamaka zokhala ndi mawonekedwe ofanana ndi C ndi L. Tsambalo ndi lolunjika ndipo limakhala lolimba kwambiri. Thupi la tsambalo lili ndi magawo awiri: chogwirira ndi nsonga ya tsambalo.

Chogwirira cha Tsamba: Chokhala ndi mabowo awiri olondola olumikizira makina a zaulimi, kuonetsetsa kuti chikhale chokhazikika komanso chosasuntha pakagwa ntchito zambiri.

Mutu wa Tsamba: Umagwiritsa ntchito njira yopindika ngati arc, kuphatikizapo masamba odulira kutsogolo ndi odulira m'mbali. Arc yake yapadera yopindika (pafupifupi 119°-120°) ndi kutalika kwake zimachepetsa kukana podula nthaka, zomwe zimapangitsa kuti nthaka isweke bwino komanso kuti igwire ntchito mozama.

Kuti akwaniritse zofunikira za kukana kugwedezeka mwamphamvu komanso kukana kutopa, thupi la tsamba limapangidwa kuchokera ku zipangizo zachitsulo zolimba kwambiri monga 60Si2Mn, 60Si2MnA, ndi 28MnSiB.

Pambuyo pokonza kutentha kwambiri (kusintha kwa gawo la martensitic), kuuma konse kwa chinthucho kumayendetsedwa pakati pa HRC 42 ndi 48, kuonetsetsa kuti tsamba silikusweka mosavuta kapena kufooka chifukwa cha mphamvu yayikulu. Kuphatikiza apo, mitundu ina imakhala ndi chophimba cha hot-melt alloy pamwamba pa tsamba, chomwe sichimangowonjezera kukana kuwonongeka komanso chimakhala ndi ntchito "yodzinola" - ndiko kuti, chimasunga kuthwa kwa m'mphepete mwa tsamba panthawi yogwiritsidwa ntchito, kuchepetsa kugwiritsa ntchito mphamvu ndikusunga mphamvu.

Chogulitsachi chimagwirizana kwambiri ndi mathirakitala akuluakulu ndi apakatikati, ndipo ndi choyenera kwambiri pokonzanso malo, kudula udzu wakale, ndi kukonza ming'alu m'malo ouma, m'malo otsetsereka komanso otsetsereka pang'ono. Chingathe kuswa bwino nthaka yolimba, kuwonjezera kutseguka kwa nthaka, komanso kupereka malo omasuka komanso opumira oti mbewu zibzalidwe pambuyo pake.
