Cross groove pan head self drilling screws

Pan head screw ndi chomangira chokhala ndi mutu wozungulira kapena wa hemispherical, womwe nthawi zambiri umapangidwa ndi chitsulo kapena chitsulo chosapanga dzimbiri. Shank ya pan head screw ndi yozungulira ndipo imatha kulumikiza zinthu ziwiri kapena zingapo palimodzi. Zomangira zapamutu zimagwiritsidwa ntchito kwambiri.

Cross pan head self tapping screws ndi yoyenera kukonza zitsulo zopyapyala zosiyanasiyana, matabwa, mapepala apulasitiki, ndi zida zina. Pokongoletsa kunyumba, zomangira za cross pan head self tapping zimagwiritsidwa ntchito kwambiri kutseka zitseko za zitseko ndi mazenera, kukhazikitsa masitovu okhala ndi khoma, kukhazikitsa nyale zapa desiki, ndikukonza mipando yosiyanasiyana. Popanga mafakitale, zomangira za cross pan head self tapping zimagwiranso ntchito yofunika kwambiri ndipo ndi zomangira zomwe amakonda zolumikizira zida zosiyanasiyana zachitsulo.

Malinga ndi mfundo za dziko, mfundo za mtanda poto mutu self tapping zomangira amagawidwa M3-M6, ndipo zipangizo anawagawa chitsulo ndi zitsulo zosapanga dzimbiri, ndi kutalika osiyanasiyana 6mm kuti 200mm.

Zomangira zapamutu zili ndi mawonekedwe apamwamba kwambiri monga kutchinjiriza, kusakhala ndi maginito, kukana dzimbiri, kukongola, komanso kusachita dzimbiri. Komano, mapulasitiki osinthidwa aumisiri ali ndi mphamvu zofananira komanso kukana zitsulo. Zomangira za pulasitiki zomwe zimatchedwa zomangira za nayiloni, ndikuwonjezera 30% ulusi wagalasi, zimakhala ndi makina abwino kwambiri kuposa nayiloni wamba. Zida zomwe zimagwiritsidwa ntchito popanga zomangira za pulasitiki zikuchulukirachulukira, ndipo magwiridwe antchito awo akuyenda bwino nthawi zonse, ndipo magawo omwe amawagwiritsa ntchito akukulirakulira. Mafotokozedwe ndi kukula kwa zomangira za pulasitiki ndizokwanira ndipo zimakwaniritsa zosowa za zochitika zosiyanasiyana

1. Wamba poto mutu zomangira

Zomangira zapamutu wamba ndiye chitsanzo choyambirira cha zomangira zapamutu, zokhala ndi mutu wozungulira komanso shaft yozungulira. Zowononga zamtunduwu zimagwiritsidwa ntchito kwambiri m'magawo monga kupanga makina, zomangamanga, ndi zida zapanyumba.

2. Theka lozungulira mutu screw

Mutu wa hafu yozungulira mutu wononga ndi hemispherical, ndipo maonekedwe ake ndi okongola kuposa wamba poto mutu zomangira. Zomangira zamutu zozungulira theka zimagwiritsidwa ntchito m'magawo monga zinthu zapakhomo, zoseweretsa, ndi zinthu zamagetsi.

3. washer mutu screw

Chotsukira mutu wa washer ndi washer wokwezedwa womwe umawonjezeredwa pamutu wa poto wamutu, zomwe zingapangitse kuti wonongazo zikhale zotetezeka. Zowononga zamtunduwu zimagwiritsidwa ntchito kwambiri m'magawo monga kupanga makina, zida zamasewera, ndi zomangamanga.

4. Msomali wamutu woonda

Poyerekeza ndi zomangira zapamutu wamba, zomangira zowonda zimakhala ndi mutu wocheperako komanso shaft yocheperako. Misomali yamutu wopyapyala imagwiritsidwa ntchito kwambiri m'magawo monga zinthu zapakhomo ndi zinthu zamagetsi.
