Mhlawumbi ujonge umzobo okanye iphepha elithile elikushiye ukukrwela intloko. 1.5 u 100mm u 5 u - yenye yezo ngqwalasela engekho semgangathweni kodwa uyibona endle, ngokuphindaphindiweyo ukusuka kwimizobo emidala okanye izenzo ezithile zengingqi. Idla ngokukhomba ku-a iqhosha lebholithi okanye i-U-bolt, kodwa ukuyichaza kufuna ukutolikwa kwentsimi, kungekhona nje ulwazi lwencwadi. Makhe sichaze oko umntu anokuthi athetha kona kunye nalapho i-specs yehlabathi yokwenyani ingcolisa.

Ukucacisa iNotation: Ayisiyo ISO

Okokuqala, ukuba udibanise phakathi kwamanani. Kwiimeko ezininzi ezisebenzayo, ngakumbi kwimizobo ethile okanye i-niches yokwakha, u-u sisishunqulelo sedayamitha yegama. Ngoko ke u-1.5 u uhlala eguqulela ku-M12. Ngoba? Kuba i-intshi eyi-1.5 imalunga ne-38.1mm, kodwa akukho mntu wenza i-38mm U-bolt. Lilifa lokuguqulwa kwe-imperial-to-metric apho i-1.5 yayidla ngokutshintshelwa i-M12 (i-12mm ibe yintambo eqhelekileyo esondeleyo). Ndiyibonile le nto ibangela ukulibaziseka kweprojekthi yeeveki ezimbini xa injineli encinci yayalela iintonga zokwenyani ze-1.5-intshi yedayamitha - zafika, kwaye zagqithiswa ngokuhlekisayo kwisicelo.

I-100mm u icace ngakumbi - loo nto iphantse yangaphakathi ubude bomlenze, okanye ububanzi bangaphakathi be-U-shape. Oku kubalulekile. Ukulinganisa oku ukusuka ngaphakathi komnye umlenze ukuya ngaphakathi komnye, kungekhona ngaphandle. A 100mm ngaphakathi ububanzi iqhelekile ukuba clamping ngeenxa umbhobho 4-intshi okanye amalungu esakhiwo efanayo. Ukuba uyifumana le nto ingalunganga, i-clamp ayizukulingana.

Emva koko 5 u. Le yeyona nto inzima. Isenokuba yintambo yobude kumlenze ngamnye, kodwa i-5mm imfutshane kakhulu. Okunokwenzeka ngakumbi, ubude bomlenze ngokwawo - i-intshi ezi-5, okanye malunga ne-125mm. Ngamanye amaxesha u-u apha ngumahluli, kwaye ithetha i-intshi ezi-5. Kodwa ndikhe ndayibona ichaza i-pitch yentambo ukuba iliqhezu, nangona ingaxhaphakanga kangako. Ngaphandle komzobo opheleleyo, kuya kufuneka ucinge. Amathumbu am, ngokusekelwe kwiipateni zokucwangcisa endizilandeleyo, zithi ubude bomlenze: 125mm.

Ke, iiSpecs ezinokwenzeka kunye nendawo ekufumaneka kuyo

Ukuyiqhekeza kunye: Mhlawumbi ujonge i-U-bolt ene-M12 intambo ububanzi, i-100mm ngaphakathi ububanzi (yibize i-'A' dimension), kunye nobude bomlenze we-125mm ('B' dimension). Izinto eziphathekayo zidla ngokuba yintsimbi yekhabhoni engenanto enentsimbi eshushu-diphu ngaphandle kokuba kuchazwe ngenye indlela. I-radius ye-bend nayo ibalulekile - kwintonga ye-M12, i-radius ye-bend ye-bend iya kuba malunga ne-20-25mm ukuphepha ukuqhekeka ngexesha lokwenziwa.

Awukwazi uku-odola oko kwikhathalogu eqhelekileyo. Ukunyamezelana ngundoqo. Xa ufuna ukubamba imibhobho, ungadinga +/- 2mm ukunyamezela kububanzi obuyi-100mm. Ukuqiniswa kwesakhiwo, kunokuba nzima. Ndakhe ndafumana ibhetshi kwiworkshop yasekhaya ephose ukunyamezela ububanzi nge-3mm. Ayekhangeleka elungile, kodwa xa efakelwa kwi-conduit run, i-tension yayingalingani, nto leyo eyakhokelela ekudinweni kwangaphambi kwexesha. Kwafuneka sikhuphe yonke into.

Kulapho ukusebenzelana nomvelisi okhethekileyo kuhlawula khona. Umzekelo, I-Sunnian Zitai Festener Fishaner Comment Com. isebenza ngaphandle kweYongnian, eyona dolophu inkulu yase China. Iwebhusayithi yabo, https //wwww.ziitasteners.com, yindawo yoshishino eqhelekileyo, kodwa ixabiso likwisakhono sabo sokuvelisa. Ukuba kuloo hub kuthetha ukuba babone yonke into engaqhelekanga phantsi kwelanga. Unokubathumela umzobo we-1.5 u-100mm u-5 u, kwaye iqela labo lobunjineli liya kubuya nomzobo ocacileyo woqinisekiso phambi kokuveliswa. Indawo yabo kufutshane neendlela ezinkulu zezothutho ezifana neBeijing-Guangzhou Railway kunye neBeijing-Shenzhen Expressway ayisiyobhoilerplate kuphela - iguqulela kulungiselelo oluthembekileyo lwe-odolo eninzi, ebaluleke ngaphezu kokuba unokucinga xa ulinde inxalenye ebalulekileyo.

Imigibe eqhelekileyo kunye nokuqwalaselwa kwezinto eziphathekayo

Ungaze ucinge ngezinto. Loo notation ayithethi nto ngebakala. Kuba a iqhosha lebholithi ukubamba isibiyeli sokukhupha i-non-critical exhaust, mhlawumbi iBanga lesi-4.8 lilungile. Ukukhusela ilungu elithwele umthwalo, uya kufuna iBanga lesi-8.8 okanye ngaphezulu. Ndiyifunde kwangoko le nto. Isetyenziselwe i-generic, intsimbi ethambileyo ye-U-bolt kwintaba yokuhambisa engcangcazelayo. Yacheba kwisithuba seenyanga ezintandathu. Uhlalutyo lokungaphumeleli lubonise amandla aphantsi kwesivuno kunye nokudinwa okubangelwa yi-vibration. Ixabiso lenxalenye yayingabalulekanga; ixabiso lexesha lokuphumla lalingekho.

Gqiba yenye into ethe cwaka. I-Hot-dip galvanizing (HDG) iqhelekile kwi-corrosion resistance, kodwa ubukhulu bunokuchaphazela ukulingana komsonto. I-Electro-galvanizing iyancipha. Ukuba i-clamp yeyommandla wesityalo sekhemikhali, unokufuna idyasi ye-zinc engqindilili okanye ukwahluka kwentsimbi engenastainless njengo-304 okanye 316. Ubhalo alunakukuxelela oku. Kufuneka uyifumane kumxholo wesicelo, osoloko ungekho kwisicelo sokuqala.

Kwakhona, ungalibali amantongomane kunye neewasha. Ngaba zibandakanyiwe? Ngaba ziyi-hex nuts okanye i-dome nuts? Ngaba iiwasha zesikweri (eziqhelekileyo kwizicelo ze-U-bolt zokuthintela ukutsalwa) okanye zingqukuva? Inkcazo engaphelelanga ikhokelela kwikhithi engaphelelanga. Ndiye ndahambisa apho i-U-bolts yayigqibelele, kodwa i-hex nuts ezibonelelweyo yayilibakala elingalunganga, lidala ikhonkco elibuthathaka kwindibano.

Inkqubo yoXhobo lweHlabathi lokwenyani

Xa ndifumana umbuzo onje, intshukumo yam yokuqala ayikokuvula ikhathalogu. Kukubuza imibuzo. Yintoni ebambekayo? Ziziphi iimeko zokusingqongileyo? Ngaba kukho umthwalo oguqukayo okanye ukungcangcazela? Ngaba kukho inxalenye yelifa esinokuyibuyisela umva-injineli? Ngokufuthi, lowo ubuzayo unenxalenye eyophukileyo esandleni. Ifoto kunye nomlinganiso we-caliper uxabisa iwaka lamaphepha.

Emva koko, ndiza kusondela kumenzi kunye ne-RFQ ecacileyo: i-M12 U-bolt, ububanzi obuphakathi kwe-100mm (+ 1/-0mm ukunyamezela), ubude bomlenze 125mm, iBanga le-8.8 yensimbi, i-hot-dip galvanized, kunye ne-2x M12 yeBanga lesi-8 i-hex nuts kunye ne-2x yesikwele se-washers nge-bolt. Oko kuphelisa ukungacaci. Inkampani efana nale ikhankanywe ngasentla nguHandan Zitai inokucaphula oko ngokuchanekileyo. Basenokude bacebise i-tweak yoyilo oluncinci-enje ngeradiyasi egobileyo enkulu yokumelana nokudinwa okungcono-ngokusekwe kumava abo emveliso.

Isinyathelo sokugqibela sihlala singumzekelo womyalelo. Ungaze uzibophelele ekuqhutyweni kwemveliso yamaqhekeza angama-5000 ngaphandle kokuvavanya isampuli ye-10. Lixabiso elincinci langaphambili elithintela ilahleko enkulu esezantsi. Le nkqubo ijika umtya ofihlakeleyo weempawu ezifana ne-1.5 u 100mm u 5 u into ethembekileyo, icandelo elibonakalayo elenza umsebenzi walo.

Ukuyisonga: Ukusuka kwiNotation ukuya kwiNut & Bolt

Ngoko ke, ukuphendula ngokuthe ngqo isihloko: Iimpawu ozifunayo mhlawumbi yi-M12 x 100mm (ububanzi bangaphakathi) x ~ 125mm (ubude bomlenze), kodwa yijometri leyo. Iimpawu ezipheleleyo kufuneka zibandakanye ibakala lemathiriyeli, ukugqiba, ukunyamezela, kunye nehardware encedisayo. Ubhalo lwantlandlolo yindawo yokuqala, umkhondo oshiywe yinjineli yangaphambili okanye umyili. Umsebenzi wakho kukuba ube ngumcuphi, ugcwalise izikhewu ngomxholo kunye namava, emva koko unxibelelane ngokucacileyo nomenzi.

Ngala manqaku angekho mgangathweni agcina lo mmandla unomdla. Bakunyanzela ukuba ucinge, ubuze, kwaye uqonde isicelo, hayi nje inani lenxalenye. Ukuxhomekeka kumnikezeli onolwazi olunzulu lwemveliso kunye nolwazi lwesicelo, ngakumbi ukusuka kwisiseko esigxininisiweyo sokwenza izinto njengeYongnian, kudla ngokuba ngumahluko phakathi kofakelo olugudileyo kunye nokulungiswa kwentsimi okuxabisa kakhulu. Ngexesha elizayo xa ubona i-spec efana nale, ungayiboni njengephazili, kodwa njengesiqalo sencoko kunye nocweyo lwakho okanye umenzi. Kulapho inkcazo yokwenyani ichazwa khona.
