Zogulitsa Zamalonda
(1) Zinthu Zakuthupi ndi Mphamvu
Chitsulo Chapamwamba: Chopangidwa ndi chitsulo chapamwamba kwambiri cha alloy monga 42CrMoA, kuonetsetsa kuti bolt ili ndi mphamvu zambiri komanso kulimba kwabwino kuti ipirire kukhudzidwa kwakukulu komanso kugwedezeka kwa zofukula ndi ma bulldozers pansi pazovuta zogwirira ntchito.
Kalasi Yamphamvu Yapamwamba: Magulu amphamvu odziwika amaphatikiza 8.8, 10.9, ndi 12.9. Mabawuti a giredi 10.9 ali ndi mphamvu yolimba ya 1000-1250MPa ndi mphamvu zokolola za 900MPa, zomwe zimakwaniritsa zofunikira zamakina ambiri omanga; Ma bawuti a giredi 12.9 ali ndi mphamvu zapamwamba, zolimba za 1200-1400MPa ndi zokolola za 1100MPa, zoyenera magawo apadera omwe ali ndi zofunikira zamphamvu kwambiri.
(2) Mapangidwe ndi Kapangidwe
Mapangidwe a Mutu: Kawirikawiri mapangidwe a mutu wa hexagonal, omwe amapereka torque yayikulu yomangirira kuti atsimikizire kuti bolt imakhalabe yolimba panthawi yogwiritsidwa ntchito ndipo sizovuta kumasula. Panthawi imodzimodziyo, mapangidwe a mutu wa hexagonal ndi abwino kwa unsembe ndi disassembly ndi zida muyezo monga wrenches.
Kapangidwe ka Ulusi: Ulusi wolondola kwambiri, womwe nthawi zambiri umagwiritsa ntchito ulusi wolimba, umakhala ndi ntchito yodzitsekera yabwino. Ulusi wa ulusi umakonzedwa bwino kuti utsimikizire kukhulupirika ndi kulondola kwa ulusi, kupititsa patsogolo mphamvu yolumikizira ndi kudalirika kwa bawuti.
Mapangidwe Oteteza: Maboti ena amakhala ndi kapu yoteteza kumutu. Nkhope yakumtunda kwa chipewa choteteza ndi malo opindika, omwe amatha kuchepetsa kukangana pakati pa bawuti ndi pansi panthawi yogwira ntchito, kuchepetsa kukana, ndikuwongolera magwiridwe antchito a zofukula ndi ma bulldozers.
(3) Chithandizo cha Pamwamba
Chithandizo cha galvanizing: Kuti bolt isachite dzimbiri, nthawi zambiri imakhala ngati malata. Zosanjikiza zokhala ndi malata zimatha kuteteza dzimbiri ndi dzimbiri la bawuti m'malo achinyezi komanso owononga, kukulitsa moyo wautumiki wa bawuti.
Chithandizo cha Phosphating: Ma bolts ena amakhalanso ndi phosphated. Phosphating wosanjikiza imatha kukulitsa kuuma komanso kuvala kukana kwa bolt pamwamba, ndikuwongoleranso kukana kwa dzimbiri kwa bolt.
