Fosholo ya pulawo yolimba kwambiri yolimba

Kufotokozera Kwachidule:

Gawo lalikulu la makina a ulimi, fosholo yozama yolima, imapangidwa ndi chitsulo cha manganese champhamvu cha 65Mn ndipo imachizidwa ndi mankhwala oziziritsa. Kulimba kwa tsamba kumafika pa HRC48-52, ndipo kukana kutha kumawonjezeka katatu. Kapangidwe kake kosalala kamachepetsa kukana kusweka kwa nthaka ndi 40% ndikukhazikika kuzama kwa kulima pa 25-30cm. Yokhala ndi mabowo awiri olimbitsa, ndi yoyenera kugwiritsa ntchito mapulawu ozungulira ndi mapulawu opachikika, okhala ndi magwiridwe antchito okwana maekala 150 tsiku lililonse, zomwe zimapangitsa kuti ikhale chida chodalirika chotsimikizira mtundu wa ntchito zolima masika ndi zolima nthawi yophukira.

Fosholo ya pulawo ndiye gawo lalikulu la ulimi wa pulawo yoyimitsa thirakitala, yopangidwira makamaka ntchito zolima nthaka bwino komanso zosalimba. Imagwiritsa ntchito sayansi yapamwamba ya zipangizo ndi kapangidwe kake, zomwe zimatha kudula nthaka mosavuta, kumaliza ntchito zingapo monga kudula, kunyamula, kuphwanya, ndi kutembenuza, ndikukonza malo obzala mbewu athyathyathya, omasuka, komanso opumira bwino. Ndi chinthu chofunikira kwambiri paulimi wamakono wolondola.

1, Kukana kwabwino kwambiri kovala, kuwirikiza nthawi yamoyo

Zipangizo: Zopangidwa ndi chitsulo cha manganese cha 65Mn kapena chitsulo cha alloy chapamwamba, pambuyo pa njira yeniyeni yochizira kutentha (kuzimitsa + kutentha), gawo lodulira limafika pamlingo wovuta kwambiri (HRC 50-55 kapena kupitirira apo), pomwe thupi la fosholo limasunga kulimba kwabwino kwambiri.

Njira: Mphepete mwa njira iyi mutha kukhala ndi chophimbira cha ndodo yolumikizira chosatha kapena chigamba chothatha kusinthidwa chosatha, chomwe chimathandizira kukana kwa mapulawu achikhalidwe ndi nthawi 2-3, kukulitsa kwambiri moyo wautumiki ndikuchepetsa ndalama zosinthira nthawi yayitali.

2, kapangidwe ka makina amadzimadzi, kogwira ntchito bwino komanso kopulumutsa mphamvu

Kukonza malo: Malo ophikirawo amagwiritsa ntchito malo opangidwa ndi kompyuta kuti atsimikizire kuti nthaka ikukwera ndikutembenuka bwino pamwamba pake, ndi mphamvu yabwino yophwanya nthaka komanso kukana kofooka.

Tsamba lodzinola lokha: Ndi kapangidwe kake kapadera ka ngodya ya tsamba, imatha kusunga kuthwa kwake panthawi yogwira ntchito, kukwaniritsa zotsatira za "kudzinola lokha", kuonetsetsa kuti kulima kwake kuli kokhazikika, kuchepetsa kukana kukoka, ndikusunga mafuta a mathirakitala.

Yolimba komanso yodalirika, yokhoza kuthana ndi zovuta zogwirira ntchito

3、Kapangidwe kolimbikitsidwa: Malo onyamula katundu wofunikira amapangidwa ndi mipiringidzo yolimbikitsidwa, yomwe imakhala ndi kukana kwamphamvu komanso kukana kupindika. Ngakhale m'malo olimba ndi olimba okhala ndi miyala ndi slabs zingapo, amatha kugwira ntchito mokhazikika ndikupewa kusweka mwangozi.

Kapangidwe ka chitetezo: Mitundu ina ili ndi mabotolo achitetezo kapena njira zotetezera katundu wambiri, zomwe zimatha kuchotsedwa zokha zikakumana ndi zopinga zosagonjetseka, kuteteza chimango cha pulawo ndi makina otumizira mathirakitala kuti asawonongeke.
