Zopangira Zingwe Siyenera Kunyalanyazidwa

Zomangira zazing'ono zimalumikizana ndi moyo wathu. Ena angakane, koma timagwiritsa ntchito zinthu zomwe zimakhala ndi zomangira tsiku lililonse. Kuyambira ting'onoting'ono ting'onoting'ono zomangira pa mafoni a m'manja mpaka zomangira pa ndege ndi zombo, timasangalala ndi kufewa komwe zitsulo zimatibweretsera nthawi zonse. Ndiye, m'pofunika kuti timvetse ins and outs of screw development.

1. Chiyambi choyambirira

Screws ndi zopangidwa ndi mafakitale. Ndikovuta kutsata kupangidwa kwa zomangira zoyambira lero, koma m'zaka za zana la 15 ku Europe, zomangira zachitsulo zidagwiritsidwa ntchito ngati zomangira. Komabe, pansi pazimenezi panthawiyo, kupanga zopangira zomangira kunali kovuta kwambiri ndipo mtengo wake unali wokwera, choncho zomangira zinali zochepa kwambiri ndipo sizinagwiritsidwe ntchito kwambiri.

2. Kupita patsogolo kwakukulu

Kumapeto kwa zaka za zana la 18, kupita patsogolo kwakukulu kunapangidwa pakupanga ndi kugwiritsira ntchito zomangira. Mu 1770, wopanga zida Jesse Ramsden adapanga lathe yoyamba yodula ma screw, yomwe idalimbikitsa kupangidwa kwa makina omangira. Mu 1797, Maudsley adapanga makina opangira zitsulo zonse. Chaka chotsatira, Wilkinson anapanga makina opangira mtedza ndi bolt. Panthawiyi, zomangira zinali zodziwika bwino ngati njira zokonzera, chifukwa njira yotsika mtengo yopangira idapezeka.

3. Kukula kwanthawi yayitali

M'zaka za zana la 20, mitundu yosiyanasiyana ya mitu ya screw idawonekera. Mu 1908, lalikulu mutu Robertson screw adayanjidwa chifukwa chosasunthika pakuyika. Mu 1936, zida za mutu wa Phillips zidapangidwa ndi zovomerezeka, zomwe zimakhala zolimba komanso zolimba kuposa screw ya Robertson.

Pambuyo pa zaka za zana la 21, mitundu ya zomangira imakhala yosiyana kwambiri ndipo ntchito zake zimakonzedwanso. Zochitika zosiyanasiyana zogwiritsira ntchito, monga nyumba, magalimoto, milatho, ndi zina, ndi zipangizo zosiyanasiyana monga zitsulo, matabwa, gypsum board, ndi zina zotero, zidzagwiritsa ntchito zomangira zosiyanasiyana. Njira ya chithandizo cha kutentha ndi chithandizo chapamwamba cha zomangira zimakhalanso bwino nthawi zonse.

Ngati mukufuna zomangira kapena zomangira makonda, tili ndi zomwe mukuyang'ana. Tianjin Lituo Hardware ali ndi zaka 20 zazaka zambiri pakupanga ndi kugulitsa zolipirira, ndipo tidzakupatsirani ntchito zokhutiritsa.
