Cishe ubheka umdwebo noma ishidi elithile elikushiye unwaya ikhanda lakho. 1.5 u 100mm u 5 u - ingenye yalezo zimpawu ezingekho ezingeni kodwa uyibona endle, ngokuvamile isuka emidwebeni emidala noma izinqubo ezithile zesifunda. Ngokuvamile likhomba ku-a i-bolt clamp noma i-U-bolt, kodwa ukuyiqopha kudinga ukutolika kancane kwenkundla, hhayi nje ulwazi lwencwadi yokufunda. Ake sihlukanise lokho okungenzeka ukuthi othile ukusho nokuthi izici zomhlaba wangempela zimosheka kuphi.

Ukuqopha i-Notation: Akuyona i-ISO

Okokuqala, ukuthi uhlukanise phakathi kwezinombolo. Ezimweni eziningi ezingokoqobo, ikakhulukazi ezindaweni ezithile zokwenziwa noma zokwakha, u-u uyisinqamuleli sobubanzi obujwayelekile. Ngakho-ke u-1.5 u uvame ukuhumusha ku-M12. Kungani? Ngoba 1.5 amayintshi cishe 38.1mm, kodwa akekho owenza 38mm U-bolt. Ukuguqulelwa kwefa kwe-imperial-to-metric lapho u-1.5 wayevame ukushintshwa ku-M12 (12mm kuwuchungechunge oluvamile oluseduze). Ngikubonile lokhu kubangela ukubambezeleka kwephrojekthi okuthatha amasonto amabili lapho unjiniyela omncane e-oda izinti zangempela zobubanzi obuyi-intshi engu-1.5 - zafika, futhi zaba zinkulu ngokuhlekisayo ukuze kufakwe isicelo.

I-100mm u icace kakhudlwana - lokho cishe cishe ubude bomlenze wangaphakathi, noma ububanzi bangaphakathi bomumo u-U. Lokhu kubalulekile. Ukala lokhu kusukela ngaphakathi komlenze owodwa kuya ngaphakathi komunye, hhayi ngaphandle. Ububanzi bangaphakathi obungu-100mm buvamile ukubopha eduze kwepayipi elingu-4-intshi noma amalungu esakhiwo afanayo. Uma wenza lokhu kungalungile, i-clamp ngeke ilingane.

Bese 5 u. Lona olukhohlisayo. Kungaba ubude bentambo emlenzeni ngamunye, kodwa u-5mm mfishane kakhulu. Ngokunokwenzeka, ubude bomlenze ngokwawo - ama-intshi angu-5, noma cishe u-125mm. Kwesinye isikhathi elithi u lapha liyisihlukanisi, futhi lisho amayintshi angu-5. Kodwa futhi ngike ngakubona kuchaza intambo yentambo uma iyingxenyana, nakuba lokho kungavamile. Ngaphandle komdwebo ogcwele, kufanele ucabange. Amathumbu ami, ngokusekelwe emaphethini oku-oda engiwalandeleyo, athi ubude bomlenze: 125mm.

Ngakho-ke, Ama-Specs Angenzeka nokuthi Kuphi Umthombo

Ukuyihlanganisa: Cishe ufuna i-U-bolt enobubanzi bentambo engu-M12, ububanzi obuyi-100mm ngaphakathi (yibize ngo-‘A’ dimension), kanye nobude bomlenze obungu-125mm (‘B’ dimension). Okubalulekile kuvame ukuba yinsimbi ye-carbon plain ene-hot-dip galvanized finish ngaphandle kwalapho kucaciswe ngenye indlela. Irediyasi yokugoba nayo ibalulekile - endongeni engu-M12, irediyasi yokugoba ejwayelekile ingaba ngu-20-25mm ukugwema ukuqhekeka ngesikhathi sokwakha.

Awukwazi uku-oda lokho kukhathalogi ejwayelekile. Ukubekezelelana kuyisihluthulelo. Ukuze ubambe amapayipi, ungase udinge ukubekezelela okungu-+/- 2mm kububanzi obungu-100mm. Ngokuqinisa isakhiwo, kungase kuqine. Ngake ngathola inqwaba endaweni yokusebenzela ephuthelwe ukubekezelela ububanzi ngo-3mm. Ayebukeka elungile, kodwa lapho efakwa ku-conduit run, ukungezwani kwakungalingani, okuholela ekukhathaleni ngaphambi kwesikhathi. Kwadingeka kukhishwe yonke into.

Yilapho ukusebenza nomkhiqizi okhethekile kukhokha khona. Ngokwesibonelo, I-Handan Zitai Fetesser Comment Co, Ltd. isebenza e-Yongnian, okuyinhloko-dolobha esheshayo yaseChina. Iwebhusayithi yabo, https://www.zitaifasteners.com, isayithi lemboni elijwayelekile, kodwa inani lisemandleni abo okukhiqiza. Ukuba kuleso sikhungo kusho ukuthi babone yonke into eyinqaba ngaphansi kwelanga. Ungabathumela umdwebo ongu-1.5 u 100mm u 5 u, futhi ithimba labo lonjiniyela cishe lizobuya nomdwebo ocacile ukuze uqinisekiswe ngaphambi kokukhiqizwa. Indawo yabo eduze kwemizila emikhulu yezokuthutha efana ne-Beijing-Guangzhou Railway kanye ne-Beijing-Shenzhen Expressway ayiyona nje i-boilerplate - ihumusha ku-logistics ethembekile yama-oda amaningi, okubaluleke kakhulu kunalokho obungacabanga lapho ulinde ingxenye ebalulekile.

Izingibe Ezivamile Nokucatshangelwa Kwezinto Ezibalulekile

Ungalokothi ucabange indaba. Leyo notation ayisho lutho ngebanga. Okwe-a i-bolt clamp ubambe ibakaki le-exhaust elingabalulekile, mhlawumbe iBanga lesi-4.8 lilungile. Ukuze uthole ilunga elithwala umthwalo, ungafuna iBanga 8.8 noma ngaphezulu. Ngifunde lokhu kusenesikhathi. Kusetshenziswe i-generic, i-U-bolt yensimbi emnene ukuze kukhweze isihambisi esidlidlizayo. Yagunda phakathi nezinyanga eziyisithupha. Ukuhlaziywa kokwehluleka kukhombise amandla esivuno esiphansi kanye nokukhathala okubangelwa ukudlidliza. Izindleko zengxenye zazingelutho; izindleko zokuphumula zazingekho.

Qeda kungenye i-spec ethule. I-Hot-dip galvanizing (HDG) ijwayelekile ukumelana nokugqwala, kodwa ukujiya kungathinta ukulingana kwentambo. I-Electro-galvanizing incane. Uma i-clamp ingeyendawo yezitshalo zamakhemikhali, ungase udinge ijazi le-zinc elijiyile noma insimbi engagqwali efana no-304 noma 316. I-notation ngeke ikutshele lokhu. Kufanele uwuthole kumongo wohlelo lokusebenza, ovame ukungabikho esicelweni sokuqala.

Futhi, ungakhohlwa amantongomane namawasha. Ingabe afakiwe? Ingabe amantongomane e-hex agcwele noma amantongomane edome? Ingabe amawasha ayizikwele (avamile uma usebenzisa i-U-bolt ukuvimbela ukudonsa) noma ayindilinga? Ukucaciswa okungaphelele kuholela kukhithi engaphelele. Ngike ngadiliva lapho ama-U-bolts ayephelele khona, kodwa amantongomane e-hex anikeziwe ayeyibanga elingalungile, okwenza isixhumanisi esibuthakathaka emhlanganweni.

I-Real-World Sourcing Process

Uma ngithola umbuzo ofana nalona, umnyakazo wami wokuqala akukhona ukuvula ikhathalogi. Kuwukubuza imibuzo. Yini i-clamping? Yiziphi izimo zemvelo? Ingabe kukhona ukulayisha okuguquguqukayo noma ukudlidliza? Ingabe ikhona ingxenye yefa esingahlehlisa ngayo unjiniyela? Ngokuvamile, umuntu obuzayo unengxenye ephukile esandleni. Isithombe nesilinganiso se-caliper zibiza inkulungwane yamashidi acacisiwe.

Bese, ngisondela kumkhiqizi one-RFQ ecacile: I-M12 U-bolt, ububanzi obuyi-100mm ngaphakathi (+1/-0mm ukubekezelelana), ubude bomlenze obungu-125mm, insimbi yeBanga 8.8, i-hot-dip galvanized, enamantongomane angu-2x M12 eBanga lesi-8 le-hex kanye namawasha ayisikwele angu-2x ngebhawodi ngalinye. Lokho kuqeda ukungaqondakali. Inkampani efana no-Handan Zitai oshiwo ngenhla ingacaphuna lokho ngokuqondile. Bangase baphakamise ngisho ne-tweak yedizayini encane - njengerediyasi yokugoba ethe ukukhudlwana yokumelana nokukhathala okungcono - ngokusekelwe kumuzwa wabo wokukhiqiza.

Isinyathelo sokugcina sihlala siyisampula. Ungalokothi uzibophezele ekukhiqizeni izingcezu ezingu-5000 ngaphandle kokuhlola isampula engu-10. Hlola ubukhulu, ikhwalithi yochungechunge, ukunamathela kokunamathela, futhi uzihlole. Kuyindleko encane yangaphambili evimbela ukulahlekelwa okukhulu komfula. Le nqubo ishintsha uchungechunge oluyimfihlo lwezinhlamvu ezifana no-1.5 u 100mm u 5 u ibe ingxenye ethembekile, ebonakalayo eyenza umsebenzi wayo.

Ukuyigoqa: Kusukela ku-Notation kuya ku-Nut & Bolt

Ngakho-ke, ukuze uphendule ngokuqondile isihloko: Imininingwane oyidingayo cishe i-M12 x 100mm (ububanzi bangaphakathi) x ~ 125mm (ubude bomlenze), kodwa lokho kuyijometri kuphela. Imininingwane egcwele kufanele ifake ibanga lempahla, isiphetho, ukubekezelela, kanye nezingxenyekazi zekhompuyutha ezisizayo. Umbhalo wokuqala uyisiqalo, umkhondo oshiywe unjiniyela wangaphambilini noma umhleli. Umsebenzi wakho wukuba umseshi, ugcwalise izikhala ngomongo nolwazi, bese ukhuluma lokho ngokucacile nomqambi.

Yilezi zimpawu ezingajwayelekile ezigcina lo mkhakha unentshisekelo. Bakuphoqa ukuthi ucabange, ubuze, futhi uqonde uhlelo lokusebenza, hhayi inombolo yengxenye kuphela. Ukuthembela kumnikezeli onolwazi olujulile lokukhiqiza nolwazi lwezinhlelo zokusebenza, ikakhulukazi kusukela kusisekelo sokukhiqiza esigxilile esifana ne-Yongnian, ngokuvamile kuwumehluko phakathi kokufakwa okushelelayo kanye nokulungiswa kwensimu ebizayo. Ngokuzayo uma ubona i-spec efana nalena, ungayiboni njengendida, kodwa njengesiqalo sengxoxo neshabhu yakho noma nomkhiqizi. Yilapho okucaciswa khona kwangempela.
