Kuyambira The Attack Misomali

Self-tapping Screws
Self-tapping screw ndi mtundu wa ulusi womangira, womwe umabowola ulusi wachikazi mu dzenje lobowoledwa kale lazitsulo kapena zinthu zopanda zitsulo.

Chiyambi cha Zamalonda
Chifukwa chakuti imadzipanga yokha kapena imatha kugogoda ulusi womwe umafanana nawo, imakhala ndi luso loletsa kumasula ndipo imatha kusonkhanitsidwa ndi kupasuka.Zida za misomali zodzipangira zokha zimatha kugawidwa kukhala zitsulo za carbon ndi zitsulo zosapanga dzimbiri, zomwe zitsulo za carbon zimakhala makamaka 1022 sing'anga carbon steel, zomwe nthawi zambiri zimagwiritsidwa ntchito pazitseko, mazenera ndi mapepala achitsulo.Mutu wake ndi malo onyamula opangidwa ndi gawo lomwe mbali yake imodzi imapangidwa kukhala mawonekedwe okulirapo.
Pakupanga ulusi ndi kudula ulusi, mutu wa Flat Countersunk, mutu wa Oval Countersunk, Pan mutu, Hex ndi Hex washer Head ndizofunikira kwambiri, zomwe zimakhala pafupifupi 90% ya zomangira zonse zodzibowolera.Mitundu ina isanu ndi Flat Undercut, Flat Trim, Oval Undercut, Oval Trim, ndi Fillister, yomwe imakhala yochepa kwambiri.

Chitukuko
Panthawi imeneyo, ankagwiritsidwa ntchito makamaka pogwirizanitsa mapepala achitsulo pazitsulo za air conditioning, choncho ankatchedwanso zitsulo zachitsulo.Pambuyo pazaka zopitilira 80, imatha kugawidwa m'magawo anayi - kupanga ulusi, kudula ulusi, kugudubuza ulusi ndikudzibowolera.
Zomangira zodzipangira ulusi zimapangidwa mwachindunji kuchokera ku zomangira za malata, ndipo zomangira zopangira ulusi, dzenje liyenera kubowoledwa pasadakhale, ndiye kuti wonongazo zimakulungidwa mu dzenje.
Ulusi wodzicheka wodzibowoleza umadula notchi imodzi kapena zingapo kumapeto kwa ulusi, kotero kuti wononga ikakulungidwa mu dzenje lobowoledwa kale, mchira ndi dzino la wononga zingagwiritsidwe ntchito kudula chachikazi chofananira. ulusi wofanana ndi kugunda.Itha kugwiritsidwa ntchito m'mbale zokhuthala, zolimba kapena zosalimba zomwe sizosavuta kuumba.
Zomangira zomangira zokha ulusi zimapangidwa mwapadera ndi ulusi ndi malekezero amchira, kotero kuti zomangirazo zitha kukulungidwa paokha ulusi waakazi pansi pa kukanikiza kwakanthawi.Panthawi imodzimodziyo, zinthu zozungulira dzenje zimatha kudzaza mosavuta danga la ulusi ndi dzino pansi pa zomangira zokhazokha.Chifukwa mphamvu yake yolimbana ndi yaying'ono kuposa ya zomangira zodzigudubuza, imatha kugwiritsidwa ntchito muzinthu zokhuthala, torque yomwe imafunikira pozungulira imayendetsedwa bwino, ndipo mphamvu ikaphatikizika imakhala yokwera.Tanthauzo laumisiri la ulusi wodzigudubuza wodzigudubuza ndilapamwamba komanso lomveka bwino kuposa kupanga kapena kudzicheka tokha pazitsulo zopangira kutentha, zomwe zimapangitsa kuti ulusi wodzigudubuza ukhale "chomangira" chomangira.
Chophimba chodzibowola sichifunikira kukumba kale, komwe kungathe kupulumutsa mtengo ndikuphatikiza kubowola, kubowola ndi kubowola.Kulimba kwapamwamba ndi kulimba kwapakati kwa wononga mchira wa kubowola ndizokwera pang'ono kuposa zomangira zodzibowolera zokha, chifukwa pirani ya mchira wabowoyo ili ndi ntchito yowonjezereka yobowola, ndipo zomangira zobowola zimafunikirabe mayeso olowera kuti ayese screw akhoza kubowola ndi kugogoda ulusi mkati mwa nthawi yotchulidwa.

Gulu
Mutu wozungulira: Ndiwo mutu womwe unkagwiritsidwa ntchito kwambiri m'mbuyomu.
Mutu wathyathyathya: kapangidwe katsopano kamene kamatha kusintha mutu wozungulira ndi mutu wa bowa.Mutu uli ndi m'mimba mwake waukulu, ndipo chigawo cha mutu chimagwirizanitsidwa ndi m'mphepete mwapamwamba, zomwe zimapangitsa kuti aziyendetsa galimoto yothamanga kwambiri.
Mutu wa hexagon: Uwu ndi mtundu wokhazikika womwe torque imayikidwa pamutu wa hexagonal.Amadziwika ndi kudula ngodya zakuthwa kuti zitseke pafupi ndi kulekerera.Ndi yoyenera pamitundu yosiyanasiyana yokhazikika komanso ma diameter osiyanasiyana a ulusi.
Mitundu yoyendetsa: slotted, Philips, ndi pozi .
Miyezo: National Standard (GB), German Standard (DIN), American Standard (ANSI) ndi British Standard (BS)

Zokhazikika
Pakalipano, pali mitundu iwiri ya zomangira zomwe zimagwiritsidwa ntchito ku China: mutu wa countersunk ndi mutu wa pan.Chithandizo chawo chomaliza nthawi zambiri chimakhala plating ya buluu ya zinc, ndipo amazimitsidwa panthawi yopanga, zomwe timazitcha kuti chithandizo cha kutentha, kuti tilimbikitse kuuma.Mtengo pambuyo pa chithandizo cha kutentha ndipamwamba kwambiri kuposa momwemo popanda chithandizo cha kutentha, koma kuuma kwake sikuli kofanana ndi pambuyo pa chithandizo cha kutentha, kotero zimadalira zomwe ogwiritsa ntchito amagwiritsa ntchito.

Kugwiritsa ntchito
Zomangira zokhoma zokha zimagwiritsidwanso ntchito polumikiza mbale zachitsulo zopyapyala.Ulusi wake ndi ulusi wamba wokhala ndi gawo la mtanda wa arc triangular, ndipo pamwamba pa ulusi umakhalanso ndi kuuma kwakukulu.Chifukwa chake, polumikiza, screw imathanso kugunda ulusi wamkati mu dzenje la pansi pa ulusi wa chidutswa cholumikizidwa, ndikupanga kulumikizana.Mtundu uwu wa screw umadziwika ndi torque yotsika komanso yotseka kwambiri.Imagwira ntchito bwino kuposa zomangira wamba zodzigugulira ndipo zitha kugwiritsidwa ntchito m'malo mwa zomangira zamakina.
Zomangira pawokha pa wallboard zimagwiritsidwa ntchito polumikizana pakati pa gypsum wallboard ndi metal keel.Ulusi wake ndi ulusi wapawiri, ndipo pamwamba pa ulusiwo umakhala wolimba kwambiri (≥HRC53), womwe ukhoza kuthamangitsidwa mwamsanga mu keel popanda kupanga mabowo opangidwa kale, motero kupanga mgwirizano.
Kusiyana pakati pa zomangira zodzibowola ndi zomangira zokha ndikuti zomangira zomata zimayenera kudutsa njira ziwiri: kubowola ndi kugogoda.Kwa zomangira zodzibowolera, njira ziwiri zobowola ndi kubowola zimaphatikizidwa.Imagwiritsa ntchito kubowola kutsogolo kwa screw pobowola kaye, kenako imagwiritsa ntchito wononga pogogoda, kupulumutsa nthawi komanso kukonza bwino.
Pan head and hexagon head self-tapping screws ndizoyenera nthawi zomwe mutu umaloledwa kuwonekera.Zomangira za hexagon zodzigonja pamutu zimatha kugwiritsa ntchito torque yayikulu kuposa zomangira zodzigudubuza pamutu.Countersunk self-tapping screws ndi yoyenera nthawi zomwe mutu suloledwa kuwonekera.

Tanthauzo
Nthawi zambiri, zikutanthauza kuti ulusi umadzigunda, kotero kuti suyenera kugwiritsidwa ntchito ndi mtedza.Pali mitundu yambiri ya zomangira, kuphatikiza mutu wa hexagon wakunja, mutu wa poto, mutu wa countersunk ndi mutu wamkati wa hexagon.Ndipo mchira nthawi zambiri umaloza.

Ntchito
Zomangira zokha zimagwiritsidwa ntchito pazitsulo zopanda zitsulo kapena zofewa, popanda mabowo obowoledwa kale ndikugogoda;Zomangira zodziwombera zokha ndizoloza, kuti "dzidzipatulire".Zomangira zokha zimatha kubowola ulusi wofananira pazinthu zomwe zimayenera kukhazikitsidwa ndi ulusi wawo, kuti zigwirizane kwambiri.
