Zomangira za mafakitale zimapangidwa m'mitundu yosiyanasiyana

Zomangira za mafakitale zimapangidwa m'mawonekedwe ndi miyezo yosiyanasiyana. Ma alloy achitsulo ali ndi kuthekera kwakukulu koyimitsa kupsinjika kwakukulu kwambiri pogwiritsa ntchito kutentha, zomwe zimapangitsa kuti alloy iyi isankhidwe popanga mabolts achitsulo omwe amagwiritsidwa ntchito m'mafakitale. Ma ferroalloy achitsulo ali ndi kaboni wochuluka pang'ono komanso mphamvu zapamwamba kwambiri kuposa chitsulo choyera, chomwe ndi chofewa kwambiri. Zachidziwikire, kuwonjezera pa kaboni, zinthu zokhazikika monga manganese, silicon, sulfure, phosphorous, ndipo nthawi zina ngakhale vanadium (vanadium imawonjezeredwa kuzinthu zachitsulo zomwe zimafuna kusinthasintha) zimapezeka m'zinthu zachitsulo.
Mu makampani omanga, mabotolo ndi mtedza womangira amagwiritsidwa ntchito kwambiri popanga mashedi, milatho, madamu ndi malo opangira magetsi. Ndipotu, kugwiritsa ntchito mabotolo ndi mtedza womangira kumachitika mosinthana ndi kuwotcherera zitsulo, zomwe zikutanthauza mabotolo omangira kapena kuwotcherera arc pogwiritsa ntchito ma electrode, kutengera kufunika kolumikiza mbale yachitsulo ndi mtanda. Njira iliyonse yolumikizira ili ndi zabwino ndi zoyipa zake, zomwe tikambirana pansipa.
Zomangira zomangira zomwe zimagwiritsidwa ntchito polumikiza mitengo yomangira zimapangidwa ndi chitsulo chapamwamba, nthawi zambiri cha giredi 10.9. Giredi 10.9 imatanthauza kuti mphamvu yokoka ya screw yomangira ndi pafupifupi 1040 N/mm2, ndipo imatha kupirira mpaka 90% ya kupsinjika konse komwe kumayikidwa pa thupi la screw m'dera losalala popanda kusintha kosatha. Poyerekeza ndi chitsulo cha 4.8, chitsulo cha 5.6, chitsulo chouma cha 8.8, zomangira zomangira zimakhala ndi mphamvu yokoka kwambiri ndipo zimakhala ndi mankhwala ovuta kwambiri otenthetsera.
Mosiyana ndi mabotolo ndi mtedza wamba wa hexagon, mabotolo ndi mtedza wamba wa hexagon amapangidwa motsatira muyezo wa DIN931 ngati theka la magiya, malinga ndi muyezo wa DIN933 ngati magiya athunthu, ndipo zomangira za hexagonal ndizosavuta, nthawi zambiri zimapangidwa motsatira muyezo wa DIN6914. Ma mtedza olumikizirana pa zomangira amathandizanso kukhala ndi mnofu ndi kutalika kwambiri kuposa mtedza wamba wa hexagon wopangidwa ku DIN934, womwe umakhala ndi kukana kwakukulu kwa kupsinjika, wopangidwa ku DIN6915. Zomangira za kapangidwe kameneka zimakhala ndi chizindikiro cha 10HV ndipo nthawi zambiri zimakhala ndi matt black phosphating kuti zisawonongeke ndi dzimbiri kapena siliva wotentha kapena wa chrome matt, zonse ziwiri zokhala ndi chitsulo. Zimagwiritsidwa ntchito mu zinc ndipo zimakhala ndi kukana kwabwino kwa chilengedwe.
