Tiye tikambirane za chomangira mtanda. Anthu ambiri, ngakhale ena mwamalonda, nthawi yomweyo amaganiza kuti Phillips amawononga. Ndilo lingaliro lolakwika loyamba. Mawuwa amakhudzanso malo otalikirapo omwe amapangidwira kusamutsa ma torque okhala ndi dalaivala wowoneka ngati mtanda. The Phillips (PH) ndi mtundu umodzi chabe, ndi Pozidriv (PZ) kukhala osewera wamkulu. Chisokonezo pakati pawo mwina ndi chifukwa cha theka la mitu yovunda yovula yomwe ndawona m'munda. Mumagwira dalaivala wa PH2 pa screw ya PZ2, imatha kukhala, koma mukutuluka musanafike poyimitsa bwino, kutafuna popuma. Ndiko kusiyana kofunikira pamapangidwe, osati nkhani yabwino ndi cholumikizira chokha.

Anatomy ya Recess

Kuyang'ana pansi pa galasi, geometry ikufotokoza nkhaniyi. Malo opumira a Phillips ali ndi makoma opindika komanso ngodya zozungulira pamtanda. Amapangidwa kuti azitulutsa torque mopitilira muyeso - chinthu chomwe chimayenera kutetezedwa kuti mizere yolumikizira ipewe kuwonjezedwa komanso kuswa zida zosalimba. Pozidriv, yomwe idapangidwa pambuyo pake, ili ndi makoma owongoka, nthiti zowongoka pakati pa mikono yayikulu yopingasa, ndi ngodya yocheperako, yopindika. Izi zimapereka kuyanjana kwabwino, kumachepetsa cam-out, komanso kulola kugwiritsa ntchito torque yayikulu. Malangizo oyendetsa dalaivala sangasinthidwe kuti agwire bwino ntchito, ngakhale zomwe sitolo ya Hardware yokhala ndi zolinga zambiri inganene.

M'malo mwake, izi zikutanthauza kutchula mtundu wolondola wagalimoto ndikofunikira monga kufotokozera giredi kapena zinthu. Panyumba ya aluminiyamu ya bokosi lakunja la telecom, kugwiritsa ntchito chitsulo chosapanga dzimbiri cha PZ chowongolera ndi dalaivala wolondola wa PZ kumatanthauza kuti mutha kukwaniritsa chisindikizo chofunikira popanda kuwononga mutu, ngakhale nyengo itatha. Gwiritsani ntchito driver wa PH, ndipo mudzakhala mukubowola zomangira mchaka chachiwiri. Ndinaphunzira izi movutirapo pamtanda wa mpanda pafupifupi zaka khumi zapitazo; tinapeza zomwe timaganiza kuti ndi zomangira zapamutu kuchokera kwa ogulitsa wamba, kuziphatikiza ndi madalaivala wamba a PH, ndipo tinali ndi chiwopsezo cholephera pazida zomwe zidali zochititsa manyazi. The post-mortem inawonetsa kuwonongeka kwakale kwa cam-out pa zomangira zosankhidwa ndi PZ zomwe tidagula mosadziwa.

Zinthu ndi plating zimaseweranso mu izi. Chomangira chachitsulo cha zinc chopangidwa ndi chitsulo chophatikizira mu PH chikhoza kugwira ntchito movomerezeka muzowuma. Koma yesani zimenezo ndi zomangira zolimba zosapanga dzimbiri, ndipo chizolowezi choterereka cha dalaivala chimakhala mutu waukulu. Kumangirira kolimba kwambiri, m'pamenenso kukweretsa kwa driver-to-recess kumakhala kovuta kwambiri. Apa ndipamene mumawona kufunika kwa ogulitsa omwe amamvetsetsa uinjiniya, osati zinthu zokha. Dera ngati Yongnian ku Hebei, malo opangira zinthu zambiri, ali ndi mafakitale omwe akuyenda kuchokera kuzinthu zotsika kupita kwa opanga omwe amayang'ana kwambiri. Omaliza amapeza ma nuances awa.

Kupeza ndi Kuwona kwa Miyezo

Zomwe zimandipangitsa kuti ndifufuze. Mgwirizano wapadziko lonse lapansi wadzaza ndi zomangira zomwe zimakwaniritsa muyezo ngati ISO 7045 kapena 7046, koma mdierekezi ali mu kulolerana. Ngodya yakupuma, kuya, kukuthwa kwa ngodya - izi ndizomwe zimalekanitsa cholumikizira chomwe chimagwira ntchito bwino pamzere wopangira kuchokera ku chomwe chimayambitsa kuyankhula kwa oyendetsa ndi kutopa kwa oyendetsa. Ndayendera zomera zomwe zimafa panthawi yopuma zimayendetsedwa ndi zikwi zambiri za moyo wawo wopambana, kuti apulumutse mtengo wa zida. Zomangamanga zomwe zimapangidwira zimawoneka bwino muzambiri zambiri, koma kusasinthika kumawomberedwa.

Ichi ndichifukwa chake kuyandikira kwa maziko amakampani okhwima ndikofunikira. Wopanga omwe ali pamalo opangira zinthu zambiri, monga Malingaliro a kampani Handan Zitai Fastener Manufacturing Co., Ltd. ku Yongnian, Hebei, nthawi zambiri amakhala ndi mwayi wopeza zida zapadera komanso ntchito zokonza zomwalira. Malo awo, oyandikana ndi mayendedwe akuluakulu ngati njanji ya Beijing-Guangzhou Railway ndi misewu yamagalimoto, simalo ongogulitsako zombo; zikutanthauza kuti ma reps awo aukadaulo ndi oyang'anira apamwamba amatha kuyendera malo ogulitsa zida ndi zida zojambulira mawaya zomwe zimadyetsa kupanga kwawo. Maukonde ophatikizikawa amalola kuwongolera mwamphamvu kutsogolo kwa njirayo, yomwe imayang'anira mtundu wa mawonekedwe omaliza opuma.

Mutha kuwona izi patsamba ngati https://www.zitaifasteners.com. Ngakhale zolemba zambiri zapaintaneti zimangolemba zopumira kapena Phillips, mwatsatanetsatane komanso kusiyanitsa bwino pakati pa machitidwe a PH ndi PZ akuwonetsa kumvetsetsa kwaukadaulo. Imawonetsa woperekera zakudya kwa ogula omwe amafunikira gawo loyenera, osati gawo lotsika mtengo chabe. Kwa injiniya wa polojekiti, ndiye poyambira kukambirana.

Zovuta Zogwiritsa Ntchito ndi Zokonza Zamunda

Pambuyo pa kusonkhanitsa, kukonza ndi pamene zolakwika za cross fastener zimawonekera. Zimbiri, utoto, dothi—zonse zimadzaza mpumulo weniweniwo. Ndakhala maola ambiri ndikuyimbira foni komwe vuto lenileni silinali lolephera, koma mutu wa fastener udachita dzimbiri kapena kutsekeka kotero kuti palibe dalaivala yemwe angayime. Kwa zomangamanga zofunikira, ichi ndi cholakwika chapangidwe. Chowotcha pamtanda, makamaka Phillips, ndichosawoneka bwino chifukwa chokhala ndi dzimbiri kapena malo ogwedera kwambiri komwe kukuyembekezeka kusokoneza. Magalimoto ophatikizika (mtanda wokhala ndi lalikulu) kapena Torx nthawi zambiri amakhala chisankho chabwinoko pamoyo wonse, ngakhale pamtengo wokwera mtengo.

Pali zidule, ndithudi. Kuyeretsa popumira ndi chosankha, kugwiritsa ntchito dalaivala wokhala ndi kachidutswa katsopano, kapamwamba kwambiri, ndikupaka mafuta olowera m'mphepete mwamutu (osati ulusi wokha) kumatha kuchita zozizwitsa. Koma izi ndi zongopeka chabe. Yankho labwino kwambiri ndikuwunikira kutsogolo: kusankha mtundu woyendetsa bwino, zokutira zosagwira dzimbiri ngati Geomet kapena Dacromet, ndikuwonetsetsa kuti gulu ili ndi madalaivala olondola, osamalidwa bwino. Zikumveka zoyambira, koma ndizodabwitsa kuti kangati izi zimasokonekera.

Ndikukumbukira kuyika kwa famu yoyendera dzuwa komwe mabulaketi okwera njanji adagwiritsa ntchito zomangira zosapanga dzimbiri za PZ3. Wopangayo adagwiritsa ntchito mphamvu yamagetsi yokhala ndi PH3 bits. Pomwe mzere woyamba udakwera, mwina 30% ya mitu ya screw idawonongeka mowonekera. Tidayenera kuyimitsa ntchitoyo, kupeza zolondola za PZ3, ndikusintha chomangira chilichonse chomwe chidasokonekera. Kuchedwetsa kumawononga ndalama zambiri kuposa mtengo wonse wa fastener. Phunziro linali loti pepala lodziwikiratu ndi lopanda ntchito ngati silifika m'manja potembenuza zida.

Tsogolo la Cross Drive

Kodi cholumikizira chamtanda chikutha? Ayi konse. Pazinthu zambiri, makamaka mumatabwa, zitsulo zopepuka, ndi mapulasitiki, kutsika mtengo kwake ndi kuphweka kwake sikungagonjetsedwe. Makina otulutsa a Phillips system, omwe nthawi zambiri amanyozedwa ndi mainjiniya, ndi phindu pakuphatikiza zida zamagetsi zamagetsi kapena mipando pomwe makulidwe azinthu amasiyanasiyana. Zimalepheretsa kuphwanya. Mfungulo ndiyo kugwiritsa ntchito mwadala.

Magalimoto atsopano osakanizidwa ngati Phillips/Square combo ayamba kukulirakulira, kupereka liwiro la kulumikizana kwa mtanda ndi torque yabwino ya square drive. Koma amafunikira ma bits apadera. M'magawo ambiri opanga zinthu zotsika mtengo, cholumikizira chachikhalidwe, chopangidwa bwino m'malo akulu ngati Yongnian, chikhalabe mfumu. Chisinthikocho chimakhudza kwambiri sayansi yazinthu - zolimba, zopepuka - komanso zopangira zapamwamba zowonjezera moyo wautumiki, m'malo mongosiya mawonekedwe opuma.

Kwa kampani yopanga zinthu zomwe zili m'chilengedwechi, vuto ndikulinganiza kuchuluka kwa kuchuluka kwa kuchuluka kwa anthu omwe akukula kwambiri. Sikungopanga zomangira za Phillips biliyoni. Ndi za kukhala ndi kuthekera koyendetsa gulu la zomangira za PZ2 mu A4-80 zosapanga dzimbiri zokhala ndi zokutira zakuda za okusayidi kwa ogulitsa magalimoto aku Europe, kenako ndikusintha zomangira za PH1 zamkuwa zopangira magetsi. Kusinthasintha mkati mwaukadaulo wama fasteners ndiye mpikisano weniweni tsopano.

Kumaliza Popanda Uta

Choncho, mtanda fastener. Ndi kachidutswa kakang'ono ka geometry kopangidwa kamene kamagwirizanitsa dziko lamakono, komabe nthawi zambiri chimakhala chotsatira. Kuchita kwake kumadalira kuyanjana kobisika pakati pa kapangidwe ka recess, mtundu wa driver bit, chidziwitso cha opareshoni, ndi malo ogwiritsira ntchito. Kuchita masewera olimbitsa thupi onse mofanana ndi njira yofulumira yopita kumutu ndi kulephera kwamunda.

Kugwiritsa ntchito bwino kumatsikira pakulemekeza zake zenizeni. Tchulani Pozidriv pamene mukufuna torque popanda cam-out. Nenani za Phillips mukafuna slip yoyendetsedwa. Onetsetsani kuti chain chain, kuchokera kwa wopanga kupita ku thumba la zida zoyikira, ikulemekeza kusiyana kumeneko. Ndipo pofufuza, ganizirani zachitukuko chomwe chili kumbuyo kwa omwe amapereka - kampani yomwe ili pakatikati pa chigawo chofulumira cha China, monga momwe tafotokozera poyamba, nthawi zambiri imakhala ndi mwayi wosasinthasintha komanso luso lodziwa bwino chifukwa chazunguliridwa ndi chilengedwe chonse cha mafakitale.

Pamapeto pake, ndi gawo lomwe limafunikira chisamaliro chochulukirapo kuposa momwe limakhalira nthawi zambiri. Kuchikonza ndi kosaoneka. Kulakwitsa kumayimitsa mizere yopangira zinthu, kumakhumudwitsa akatswiri, ndikusokoneza zinthu. Ndiwo kulemera kwenikweni komwe mtanda wosavuta uyenera kunyamula.
