Screws ndi Bolts

Wolemba wamkulu wa Mechanics Roy Berendson amagawana phunziro lachangu pa zomangira. Malinga ndi Roy, nawu mndandanda wa mitundu isanu ndi iwiri yodziwika bwino ya zomangira ndi mabawuti zomwe mwininyumba aliyense amakumana nazo nthawi ina m'miyoyo yawo.
Zomangira za hex kapena zomangira za mutu wa hex ndi mabawuti akulu a hex (hex!), omwe amagwiritsidwa ntchito kumangirira nkhuni kumitengo kapena chitsulo kumitengo. "Mosiyana ndi ma bolts onyamula, amakonda kupota mukamawalimbitsa, kotero muyenera kugwira mutu wa bolt ndi wrench kapena socket ndiyeno mugwiritse ntchito wrench yachiwiri kuti muyimitse (kapena kumasula) mtedza," adatero Roy. . Maboti a hex ali ndi ulusi ting'onoting'ono komanso shank yosalala ndipo amapezeka muzitsulo kapena zitsulo zosapanga dzimbiri kuti agwiritse ntchito mkati kapena zitsulo zopangira malata kuti azigwiritsa ntchito kunja.
Zomangira zamatabwa zimakhala ndi ndodo yomangira matabwa. Zomangira izi zimatha kukhala ndi ulusi wosiyanasiyana. Akamangitsa nkhuni zofewa ngati paini ndi spruce, Roy akuti ndi bwino kugwiritsa ntchito zomangira zokhala ndi ulusi wochepera pa inchi. Kumbali ina, zomangira za ulusi wabwino ziyenera kugwiritsidwa ntchito pomanga matabwa olimba. Pali mitundu yosiyanasiyana ya mitu ya matabwa, koma yodziwika bwino ndi yozungulira komanso yosalala. Roy akufotokoza kuti: "Mutu wa wononga mutu wozungulira uli pamwamba pa chogwirira ntchito. Zomangira zamatabwa zimatha kukhala chitsulo chosapanga dzimbiri, mkuwa, chitsulo chosapanga dzimbiri, kapena chitsulo chopanda nyengo.
Zomangira zitsulo zamapepala zimagwiritsidwa ntchito kulumikiza zidutswa ziwiri zachitsulo pamodzi kapena kulumikiza zitsulo zamitundu ina monga mapaipi. Zomangira izi nthawi zambiri zimakhala ndi mutu wozungulira, wosalala kapena wa hex. Choyenera kukumbukira pa zomangira zachitsulo, Roy akuti, ndikuti ndizopangira ulusi. "Nsonga ya screw imapangidwa kuti idule ulusi muzitsulo zomwe zimayendetsedwa ndi screw," adatero, ndikuwonjezera kuti nthawi zambiri amatchedwa zomangira zokha. Nthawi zambiri amagwiritsa ntchito chitsulo chosapanga dzimbiri, chitsulo chosapanga dzimbiri, aluminiyamu, kapena chitsulo chosapanga dzimbiri kuti athe kupirira nyengo.
Zomangira zamakina ndi kusakaniza kwa mabawuti ang'onoang'ono ndi zomangira zomwe zimagwiritsidwa ntchito kumangiriza chitsulo kuchitsulo kapena chitsulo kupulasitiki. M'nyumba, amagwiritsidwa ntchito kuteteza zida zamagetsi, monga kulumikiza nyali ku mabokosi amagetsi. Pakugwiritsa ntchito kotere, screw ya makina imakhala dzenje momwe ulusi wofananira umakhomeredwa kapena "kuponyedwa". Zomangira zomangira zimafunikira nati ngati dzenjelo silinapangike, akutero Roy.
Socket head screw ndi zomata zamakina zomwe zimakhala ndi mutu wa socket momwe kiyi ya hex imayikidwa. Nthawi zambiri, zomangirazi zimagwiritsidwa ntchito kulumikiza zitsulo ndi zitsulo ndipo zimafuna zolimba kuti zitsimikizire kulumikizana kotetezeka. Amagwiritsidwa ntchito nthawi zambiri pamene zinthu zimatha kuchotsedwa ndikuziphatikizanso pakapita nthawi.
Maboti otsekera, omwe amadziwikanso kuti zomangira zocheperako, nthawi zambiri amakhala akulu m'mimba mwake komanso aatali kuti alowe mkati mwa matabwa ndikupanga kulumikizana kolimba popanda mwayi womasula wonongayo ikangothina. Malo odziwika bwino opeza ma propeller amtunduwu ndi ma decks, ma docks, ndi makoma omangira matabwa. Chifukwa matabwa akunja oponderezedwa amawononga, zomangirazo zimayikidwa ndi anti-corrosion anti-corrosion. Roy akufotokoza kuti: “Zimapangidwa ndi zitsulo zosapanga dzimbiri zotentha kapena zopangidwa ndi zitsulo zosapanga dzimbiri.
Bolt ya ngolo, yomwe imatha kuonedwa ngati msuweni wa lag screw, ndi bawuti yayikulu yomwe imagwiritsidwa ntchito ndi ma washer ndi mtedza kuti agwirizanitse matabwa olimba. Pansi pa mutu wozungulira wa bawuti pali chowonjezera chooneka ngati kyubu chomwe chimadula nkhuni ndikuletsa bawuti kuti zisatembenuke pamene natiyo yakhazikika. Izi zimapangitsa kuti zikhale zosavuta kutembenuza nati (simuyenera kugwira mutu wa bolt ndi wrench) ndikulepheretsa kulowa kosaloledwa. "Mtedza uli pafupi nthawi zonse kumbuyo kwa msonkhanowo. Choncho, ikangoyimitsidwa, chomangira sichikhoza kumasulidwa mosavuta chifukwa mutu wa bolt wa ngolo ndi wozungulira - ngati rivet wachikale - pliers sangathe kuchita izi. izo kapena wrench, "Roy anafotokoza.
