Mwinamwake mukuyang'ana chojambula kapena pepala linalake lomwe lakusiyani mukukanda mutu wanu. 1.5 u 100mm u 5 u - ndi chimodzi mwazolemba zomwe sizili zoyenera koma mumaziwona kuthengo, nthawi zambiri kuchokera ku zojambula zakale kapena machitidwe ena a m'madera. Nthawi zambiri amaloza ku a bolt clamp kapena U-bolt, koma kuyilemba kumafuna kutanthauzira pang'ono, osati kungodziwa zamabuku. Tiyeni tifotokoze zomwe wina angatanthauze komanso komwe zenizeni zenizeni zimasokonekera.

Kujambula Chidziwitso: Si ISO

Choyamba, kuti inu sandwiched pakati manambala. Muzochitika zambiri, makamaka muzinthu zina zopangira kapena zomangamanga, u ndi mawu ofupikitsa a m'mimba mwake mwadzina. Chifukwa chake 1.5 u nthawi zambiri amamasulira ku M12. Chifukwa chiyani? Chifukwa mainchesi 1.5 ndi pafupifupi 38.1mm, koma palibe amene amapanga 38mm U-bolt. Ndiko kutembenuka kwamphamvu kwa metric komwe 1.5 nthawi zambiri inkasinthidwa kukhala M12 (12mm kukhala ulusi wapafupi kwambiri). Ndawona izi chifukwa cha kuchedwa kwa ntchito kwa milungu iwiri pomwe injiniya wocheperako adayitanitsa ndodo zenizeni za mainchesi 1.5 - zidafika, ndipo zidakulitsidwa mwachisangalalo kuti agwiritse ntchito.

The 100mm u imamveka bwino - ndiye pafupifupi kutalika kwa mwendo wamkati, kapena m'lifupi mwake mwa mawonekedwe a U. Izi ndizovuta. Mumayesa izi kuchokera mkati mwa mwendo umodzi kukafika mkati mwa mzake, osati kunja kwake. M'lifupi mwake 100mm ndi wamba kumangirira mozungulira chitoliro cha 4-inchi kapena ziwalo zofananira. Ngati mulakwitsa izi, cholembera sichingakwanire.

Kenako 5u. Ili ndiye lachinyengo. Ikhoza kukhala kutalika kwa ulusi pa mwendo uliwonse, koma 5mm ndi yayifupi kwambiri. Mwinanso, ndi kutalika kwa mwendo wokha - mainchesi 5, kapena pafupifupi 125mm. Nthawi zina u pano ndi wolekanitsa, ndipo zikutanthauza mainchesi 5. Koma ndaziwonanso zikutanthawuza kukwera kwa ulusi ngati ndi kagawo kakang'ono, ngakhale kuti ndizochepa. Popanda kujambula kwathunthu, muyenera kuganiza. Matumbo anga, kutengera machitidwe omwe ndawatsata, amati ndi kutalika kwa mwendo: 125mm.

Chifukwa chake, Zolemba Zotheka ndi Komwe Mungatulukire

Kuying'amba pamodzi: Mwinamwake mukuyang'ana U-bolt wokhala ndi ulusi wa M12 m'mimba mwake, 100mm mkati mwake (muutcha "A' dimension), ndi kutalika kwa mwendo wa 125mm ('B' dimension). Zinthu zakuthupi nthawi zambiri zimakhala chitsulo chosapanga dzimbiri cha kaboni chokhala ndi chotsekera chomata choviyitsa, pokhapokha zitanenedwa mwanjira ina. Ma bend radius nawonso amafunikiranso - pa ndodo ya M12, utali wopindika wokhazikika ungakhale wozungulira 20-25mm kupewa kusweka panthawi yopanga.

Simungangoyitanitsa izi kuchokera pamndandanda wanthawi zonse. Kulekerera ndikofunika kwambiri. Pothirira mapaipi, mungafunike +/- 2mm kulolerana pamlingo wa 100mm. Kwa structural bracing, ikhoza kukhala yolimba. Nthawi ina ndinapeza gulu kuchokera ku msonkhano wakumaloko womwe unaphonya kulekerera kwa 3mm. Ankawoneka bwino, koma atawaika pa kanjira kanjira, kukanganako sikunali kofanana, zomwe zinayambitsa kutopa msanga. Ndinayenera kuchotsa mbali zonse.

Apa ndipamene kuchita ndi wopanga mwapadera kumalipira. Mwachitsanzo, Malingaliro a kampani Handan Zitai Fastener Manufacturing Co., Ltd. imagwira ntchito kuchokera ku Yongnian, lomwe kwenikweni ndi likulu la China. Webusaiti yawo, https://www.zitaifasteners.com, ndi tsamba lamakampani, koma mtengo wake uli pakupanga kwawo. Kukhala m'malo amenewo kumatanthauza kuti awona zosamvetseka zonse pansi padzuwa. Mutha kuwatumizira zojambula za 1.5 u 100mm u 5 u, ndipo gulu lawo la uinjiniya likhoza kubwereranso ndi zojambula zomveka bwino kuti zitsimikizidwe zisanachitike. Malo awo pafupi ndi misewu yayikulu yoyendera monga Beijing-Guangzhou Railway ndi Beijing-Shenzhen Expressway si boilerplate chabe - imamasulira kuzinthu zodalirika zamaoda ambiri, zomwe zimafunikira kuposa momwe mungaganizire mukamadikirira chinthu chofunikira.

Mavuto Odziwika Ndi Kuganizira Zakuthupi

Musaganize za nkhaniyo. Kuti u notation sikunena kanthu za kalasi. Za a bolt clamp kukhala ndi bulaketi yosafunikira kwambiri, mwina Giredi 4.8 ndi yabwino. Kuti mupeze membala wonyamula katundu, mungafune Giredi 8.8 kapena kupitilira apo. Ndinaphunzira izi msanga. Anagwiritsa ntchito chitsulo chosapanga dzimbiri, U-bolt ya U-bolt poyika chokwera chogwedezeka. Idameta m'miyezi isanu ndi umodzi. Kusanthula kulephera kunawonetsa kulimba kwa zokolola zochepa komanso kutopa koyambitsa kugwedezeka. Mtengo wa gawolo unali wochepa; mtengo wanthawi yopumira sunali.

Finish ndi chinthu china chopanda phokoso. Hot-dip galvanizing (HDG) ndiyofanana ndi kukana dzimbiri, koma makulidwe ake amatha kukhudza kukwanira kwa ulusi. Electro-galvanizing ndi woonda. Ngati chotchingacho ndi cha malo opangira mankhwala, mungafunike chotchinga cha zinki kapenanso chitsulo chosapanga dzimbiri ngati 304 kapena 316. Mawuwo sangakuuzeni izi. Muyenera kuzipeza kuchokera kuzomwe zimagwiritsidwa ntchito, zomwe nthawi zambiri sizikhala pa pempho loyamba.

Komanso, musaiwale mtedza ndi washers. Kodi aphatikizidwa? Kodi ndi mtedza wa hex kapena mtedza wa dome? Kodi ma washers ali ndi masikweya (ofala pamapulogalamu a U-bolt kuti apewe kukoka) kapena kuzungulira? Kusakwanira kwenikweni kumatsogolera ku zida zosakwanira. Ndakhala ndikupereka komwe ma U-bolts anali abwino, koma mtedza wa hex woperekedwa unali wolakwika, ndikupanga ulalo wofooka pamsonkhano.

The Real-World Sourcing Process

Ndikapeza funso ngati ili, kusuntha kwanga koyamba sikutsegula kabukhu. Ndiko kufunsa mafunso. Kodi clamping ndi chiyani? Kodi chilengedwe chili bwanji? Kodi pali dynamic load kapena vibration? Kodi pali gawo la cholowa lomwe tingathe kusintha mainjiniya? Nthawi zambiri, wofunsayo amakhala ndi gawo losweka m'manja. Chithunzi ndi muyeso wa caliper ndizofunika masauzande chikwi.

Kenako, ndimayandikira wopanga ndi RFQ yomveka bwino: M12 U-bawuti, m'lifupi mwake 100mm (+1/-0mm kulolerana), kutalika kwa mwendo 125mm, Gulu 8.8 chitsulo, otentha-kuviika kanasonkhezereka, ndi 2x M12 Giredi 8 hex mtedza ndi 2x washers lalikulu pa bolt. Zimenezo zimathetsa kusamvana. Kampani ngati yomwe tatchulayo Handan Zitai imatha kutchula izi molondola. Athanso kupereka lingaliro lakapangidwe kakang'ono - ngati utali wopindika wokulirapo pang'ono kuti asatope - kutengera zomwe adapanga.

Njira yomaliza nthawi zonse ndi dongosolo lachitsanzo. Osadzipereka kupanga zidutswa 5000 popanda kuyesa zitsanzo za 10. Yang'anani kukula kwake, mtundu wa ulusi, kumatira kwa zokutira, ndikuyesani. Ndi mtengo wocheperako wakutsogolo womwe umalepheretsa kutayika kwakukulu kutsika. Njirayi imatembenuza mndandanda wa zilembo zosadziwika bwino monga 1.5 u 100mm u 5 u kukhala chinthu chodalirika, chakuthupi chomwe chimagwira ntchito yake.

Kuchimanga: Kuchokera ku Notation kupita ku Nut & Bolt

Chifukwa chake, kuti muyankhe mwachindunji mutuwo: Zolemba zomwe mukufuna mwina ndi M12 x 100mm (m'lifupi mwake) x ~ 125mm (kutalika kwa mwendo), koma ndi geometry chabe. Zolemba zonse ziyenera kuphatikizapo kalasi yazinthu, kumaliza, kulolerana, ndi zida zowonjezera. Chidziwitso choyambirira ndi poyambira, chidziwitso chosiyidwa ndi injiniya wam'mbuyomu kapena wolemba. Ntchito yanu ndi kukhala wapolisi wofufuza, kudzaza zomwe zasokonekera ndi zomwe zasonkhanitsidwa ndi zomwe mwakumana nazo, ndiyeno lankhulani momveka bwino kwa wopanga zinthu.

Izi ndizolemba zosavomerezeka zomwe zimapangitsa kuti gawoli likhale losangalatsa. Amakukakamizani kuganiza, kukayikira, ndi kumvetsetsa tanthauzo lake, osati gawo chabe. Kudalira wothandizira yemwe ali ndi chidziwitso chozama komanso kugwiritsa ntchito, makamaka kuchokera kumalo opangira zinthu monga Yongnian, nthawi zambiri kumakhala kusiyana pakati pa kukhazikitsa kosalala ndi kukonza malo okwera mtengo. Nthawi ina mukadzawona chonga chonga ichi, musachiwone ngati chododometsa, koma ngati choyambitsa zokambirana ndi malo anu ogwirira ntchito kapena wopanga. Apa ndipamene zimafotokozera zenizeni zenizeni.
