Valani lamulo la nsapato za njanji
Panthawi yogwira ntchito bwino, pini ya njanji imazungulira pang'onopang'ono kumbuyo mu dzenje la pini, awiriwo amavala mofanana, dzenje la pini limakula pang'onopang'ono, ndipo piniyo imakhala yochepa kwambiri.Ngati opaleshoniyo ili yosayenera, monga kutembenuka kothamanga, kuyamba mwadzidzidzi, kapena kulowa m'madzi amatope, udzu, ndi zina zotero kuti atseke zikhomo, zidzachititsa kuti kumanzere ndi kumanja kwa nsapato za njanji kupanikizika kwambiri ndi kugwedezeka, ndipo zikhomozo zidzakhala zopunduka ndi zopindika.Kuzungulira, pini ndi bowo la pini zimakhala zosefukira, ndipo gawo la mikangano limangokhala pagawo laling'ono la malo olumikizana, piniyo imapangidwa pang'onopang'ono kukhala mawonekedwe opindika, ndipo dzenje la pini limakhalanso ellipse.
Kuwonjezeka kwa dzenje la pini kumapangitsanso kuti mayendedwe azitalikitsa (phoko ndi mtunda wapakati wa mabowo kumapeto onse a nsapato ya njanji), kotero nsapato ya njanji ndi gudumu loyendetsa galimoto zimagawanikana, nsapato ya njanji imavalidwa. , ndipo mano a gudumu loyendetsa galimoto amakhala ngati blade.Malinga ndi muyeso, pamene phula lasinthidwa kuchokera 174 mm mpaka 184 mm, kutsegula kwa mano oyendetsa galimoto kumasinthidwa kuchoka ku 87 mm kufika ku 97 mm, ndipo mametchi abwinobwino amawonongeka panthawiyi.
Popeza kuti mayendedwe a nsapato amatalika, amachititsanso kuti odzigudubuza adumphe pamene akuyenda, zomwe zimafulumizitsa kuvala kwa msewu wa nsapato.Pamene subsidence ya msewu wonyamukira ndegeyo ndi yaikulu kuposa 4 mm, iyenera kukonzedwa.
Kuvala kwa gawo lowongolera la nsapato ya njanji kumachitika makamaka chifukwa cha kupatuka kwa njanji, kupindika kwakukulu kwa nsapato ya njanji, komanso kugwedezeka kwakukulu kwa axial kwa wodzigudubuza ndi gudumu lowongolera.
Nsapato zamtundu wamba zotayidwa zimavalidwa kwambiri kapena zimavalidwa kudzera pagawo la meshing ndi gudumu loyendetsa.
Kukonza nsapato za njanji
Kuvala kwa nsapato za njanji kumakhala ndi magawo awiri: malo othamanga ndi dzenje la pini.Ndizosavuta kukonza.Msewu ukatha, poyambira amatsika, ndipo kuya kwake sikupitilira 2 ~ 3 mm, kumatha kukhazikika ndikukonzedwa.Kuvala kumakhala kozama, mipiringidzo yachitsulo yamitundu yosiyanasiyana imatha kudzazidwa m'mabowo molingana ndi momwe zinthu ziliri, kenako amawotcherera kuchokera kumbali zonse.Bowo la pini liyenera kubwezeretsedwanso kukula kwake ndi malo apakati a dzenje loyambirira pambuyo popera.Pachifukwa ichi, dulani dzenje la pini, ikani pini yokhazikika, kenaka mutenthe mpaka 800 ℃, kenaka pindani m'mphepete mwa khutu.Onjezani mbale yachitsulo yozungulira yozungulira kunja kwake ndikuwotcherera mwamphamvu ndi kuwotcherera kwamagetsi.Nsapato za njanji zomwe zakonzedwa motere zimatha kupitilira masinthidwe a 100.
Chitsulo cholowa m'malo mwa nsapato za njanji
Nsapato zamagalimoto zotsatiridwa nthawi zambiri zimapangidwa ndi chitsulo chambiri cha manganese chokhala ndi mbiri yazaka pafupifupi zana zogwiritsidwa ntchito.Izi ndichifukwa choti chitsulo chachikulu cha manganese chimakhala ndi chinthu chodziwika bwino, ndiko kuti, chimakhala cholimba kwambiri chifukwa cha kuchuluka kwamphamvu, ndikupangitsa kuti chikhale chosanjikiza pamwamba chomwe chimakhala cholimba komanso chosavala, ndikusungabe kulimba ndi pulasitiki yamkati mwake. wosanjikiza.Komabe, chitsulo chokwera cha manganese chimagwiritsidwa ntchito ngati nsapato ya njanji, yomwe nthawi zambiri imawonongeka msanga chifukwa cha ming'alu, mano opindika ndi kupunduka panthawi yogwiritsidwa ntchito, ndipo imakhala ndi moyo wochepa.Pofuna kuthana ndi vutoli, chitsulo chochepa chachitsulo chochepa kwambiri cha 30SiMnMoV (Ti), chomwe chimachokera kuzinthu zapakhomo ndipo n'chosavuta kupanga, chapangidwa.Zakhala zikugwiritsidwa ntchito bwino m'malo mwa chitsulo chapamwamba cha manganese kupanga nsapato zama track.
processing njira
The processing luso la nsapato ya njanji mbiri zambiri: ntchito mbiri kudula, kubowola (kukhomerera), kutentha mankhwala, kuwongola, kujambula ndi njira zina;njanji ya bulldozer ndi imodzi yokha, ndipo utoto wamba ndi wachikasu;Ndi nthiti zitatu, ndipo utoto wa utoto ndi wakuda.Zomwe zimagulidwa pambiriyo nthawi zambiri zimakhala 25MnB, ndipo kuuma komaliza kwazinthuzo ndi HB364 ~ 444.
