Zowonjezera za thirakitala zofanana ndi thirakitala zonse zozungulira za pulawo Chithunzi Chowonetsedwa

Zipangizo zozungulira za thirakitala zofanana ndi thirakitala

Kufotokozera Kwachidule:

Iyi ndi nsonga ya pulawu yolimba kwambiri yopangidwira ntchito zouma, yopangidwa ndi chitsulo cha boron chosatha, yokhala ndi kuuma komanso kulimba kwabwino. Kapangidwe kake kosalala komanso kokhuthala sikuti kokha kali ndi ngodya yakuthwa yolowera m'nthaka, zomwe zimapangitsa kuti zikhale zosavuta kudula mu nthaka yolimba yolimba, komanso kumachepetsa bwino kukanikiza nthaka ndi kukana kulima. Nsonga ya pulawu iyi imakulitsa kwambiri magwiridwe antchito a ngalande, kumasula kwambiri, ndi kutembenuza nthaka, ndikuwonjezera moyo wautumiki ndi nthawi yoposa kawiri poyerekeza ndi zowonjezera wamba. Ndi chisankho chanu chabwino kwambiri chowongolera magwiridwe antchito a ulimi ndikuchepetsa ndalama zosamalira.

Nsonga ya pulawo ndi gawo lolumikizana ndi nthaka lomwe limayikidwa kutsogolo kwa gulu la pulawo la makina a ulimi monga mapulawo ndi olima, omwe amadziwikanso kuti nsonga ya pulawo. Nthawi zambiri imakhala ngati kansalu kakang'ono kapena chisel ndipo imadula nthaka kaye ikagwira ntchito, imagwira ntchito zofunika monga kulowa, kudula, ndi kuboola nthaka. Chifukwa cha kukangana kwakukulu ndi kugundana ndi nthaka, nsonga ya pulawo ndi gawo lodziwika bwino losawonongeka komanso losatetezeka, ndipo magwiridwe ake ndi khalidwe lake zimakhudza mwachindunji kugwiritsa ntchito mphamvu, mphamvu yolima, komanso kuchuluka kwa makina onse.

Ponena za zipangizo ndi njira, nsonga zamakono zowongolera pulawo zapamwamba nthawi zambiri zimapangidwa ndi chitsulo chapadera cha manganese (monga 65Mn, U75V) kapena chitsulo cha alloy chomwe chakhala chikutenthedwa mwapadera kuti chitsimikizire umodzi wa kuuma kwakukulu ndi kulimba kwakukulu. Njira zopangira zapamwamba zimaphatikizapo kupanga, carburizing, quenching, ndi tempering treatment. Mwachitsanzo, pambuyo pa chithandizo cha carbon quenching tempering (CQT), pamwamba pa nsonga ya pulawo pakhoza kupanga singano yolimba kwambiri ngati martensitic, zomwe zimapangitsa kuti isamavute kwambiri; Pakati pake pamakhala kulimba kwamphamvu ndipo imatha kukana bwino kukhudzidwa ndi zopinga monga miyala panthawi yogwira ntchito, kuteteza kusweka.

Zogulitsa zapamwamba zimagwiritsanso ntchito kapangidwe ka kuuma kwa gradient: kuuma kwa pamwamba pa kuuma kumakhala kokwera kufika pa 53-60HRC kapena kupitirira apo kuti kupewe kuuma, pomwe kuuma kozungulira mabowo a bolt yoyikako kumakhala kochepa kuti kusunge pulasitiki wabwino ndikuletsa mabowo a bolt kuti asawonongeke chifukwa cha kupsinjika.

Ponena za kapangidwe kake, kuti zigwirizane ndi mikhalidwe yosiyanasiyana ya nthaka ndi zofunikira pakugwira ntchito, nsonga za pulawo zasinthanso kukhala mitundu yosiyanasiyana. Mwachitsanzo, nsonga yolunjika yopangidwira nthaka yomata komanso yolemera ingathandize kuchepetsa kumamatira kwa nthaka komanso kuchepetsa kukana kugwira ntchito; nsonga ya fosholo yokhala ndi mitu iwiri ikhoza kutembenuzidwa ndikupitiliza kugwiritsidwa ntchito mbali imodzi ikatha, zomwe zimapangitsa kuti ikhale yogwira ntchito kawiri. Kuphatikiza apo, nsonga zina zozama zomasula pulawo zimapangidwa ngati mutu wa nkhosa kuti ziwongolere kuyendetsa bwino nthaka ndikuchepetsa kugwiritsa ntchito mphamvu mwa kukonza mawonekedwe ake.

Ndi kupita patsogolo kwa ukadaulo, kukana kuvala kwakhala chizindikiro chachikulu choyezera ubwino wa nsonga za pulawo. Kukana kuvala kwa zinthu zotsogola zapakhomo kwafika kuwirikiza katatu kuposa zinthu wamba, ndipo nthawi yogwira ntchito imodzi imatha kupitirira maola 80 kapena kupitirira apo, zomwe zimachepetsa kwambiri nthawi yogwira ntchito ndi nthawi yosinthira ntchito zaulimi, zomwe zimapereka chitsimikizo cholimba cha kulima bwino muulimi wamakono.
