Kusiyana kwa magwiridwe antchito ndi misampha yosinthira pakati pa mabawuti amphamvu kwambiri a giredi 10.9 ndi giredi 12.9

Kuchokera pazomwe zimayambira pamakina ogwirira ntchito, kulimba kwamphamvu kwa 10.9 giredi yamphamvu kwambiri kumafika 1000MPa, pomwe mphamvu zokolola zimawerengedwa ngati 900MPa kudzera mu chiŵerengero cha mphamvu zokolola (0.9). Izi zikutanthauza kuti ikagwidwa ndi mphamvu zolimba, mphamvu yowonjezereka yomwe bolt imatha kupirira ili pafupi ndi 90% ya mphamvu yake yosweka. Mosiyana ndi izi, mphamvu zodziwikiratu za mabawuti a giredi 12.9 zawonjezeka kufika ku 1200MPa, ndipo mphamvu zokolola zimafika pa 1080MPa, kuwonetsa kulimba kwapamwamba komanso kukana zokolola. Komabe, sizochitika zonse, mabawuti apamwamba amatha kulowetsa mabawuti otsika mosasankha. Pali malingaliro ambiri okhudzana ndi izi:

1. Mtengo wamtengo wapatali: Ngakhale kuti ma bolts amphamvu kwambiri amakhala ndi ntchito yabwino, ndalama zopangira zawo zimawonjezeka moyenerera. M'malo omwe kufunikira kwamphamvu kwambiri sikofunikira, kugwiritsa ntchito mabawuti otsika kungakhale kopanda ndalama komanso koyenera.

2. Chitetezo cha zigawo zothandizira: Panthawi yokonza, nthawi zambiri pamakhala kusiyana kwadala pakati pa ma bolts ndi mtedza kuti zitsimikizire kuti moyo wautali wa bawuti ndi kuchepetsa mtengo wokonza panthawi ya disassembly ndi m'malo. Ngati m'malo mwachisawawa, zitha kusokoneza izi ndikufulumizitsa kuwonongeka kwa zida monga mtedza.

3. Zotsatira zapadera za ndondomeko: Njira zothandizira pamtunda monga galvanizing zingakhale ndi zotsatira zoipa pazitsulo zolimba kwambiri, monga hydrogen embrittlement, zomwe zimafuna kuwunika mosamala posankha njira zina.

4. Zofunikira zolimba: M'malo ena okhala ndi katundu wosinthasintha, kulimba kwa mabawuti kumakhala kofunika kwambiri. Panthawiyi, kusintha mwakhungu ma bolts amphamvu kwambiri kungayambitse kusweka koyambirira chifukwa cha kuuma kwa zinthu zosakwanira, zomwe zimachepetsa kudalirika kwa kapangidwe kake.

5. Kachitidwe ka ma alarm achitetezo: Pazinthu zina zapadera, monga zida zamabuleki, mabawuti amafunikira kusweka pansi pazifukwa zina kuti ayambitse makina oteteza. Pankhaniyi, kusintha kulikonse kungayambitse kulephera kwa ntchito zachitetezo.

Mwachidule, pali kusiyana kwakukulu muzinthu zamakina pakati pa ma bolt amphamvu kwambiri a grade 10.9 ndi grade 12.9. Komabe, muzogwiritsira ntchito, kusankha kwawo kuyenera kuganiziridwa mozama potengera zosowa zenizeni za zochitikazo. Kufunafuna mwamphamvu kwambiri sikungowonjezera ndalama zosafunikira, komanso kumabweretsa ngozi zachitetezo. Ndikofunikira kumvetsetsa bwino momwe magwiridwe antchito ndi zolepheretsa kugwiritsa ntchito ma bolts osiyanasiyana, kuwonetsetsa kuti ma bolts osankhidwa amatha kukwaniritsa zofunikira zogwirira ntchito ndikuwonetsetsa chitetezo ndi kudalirika kwa kapangidwe kake.
