Guhitamo uburenganzira Imiterere minini ya hexagonal bolt ntabwo ari ugufata inzira nini cyangwa nziza cyane kuruhande. Byerekeranye no guhuza imbaraga zibintu, kurangiza hejuru, kugereranya ibipimo, hamwe nimyitwarire yo kwishyiriraho inzira nyayo-yuzuye imitwaro-cyane cyane mumwanya urwanya umwanya, guhuza ikiraro, cyangwa sisitemu yo hejuru yumuyaga mwinshi. Muri Hebei Dewell Metal Products Co., LTD, twatanze toni zirenga 12.000 za bolts zubatswe mumishinga hirya no hino mubuyapani, Ubudage, ndetse na Amerika yo mu burengerazuba bwo hagati - kandi gutsindwa kwose twakoze iperereza byaturutse kuri imwe mu makosa atatu: guhitamo amanota mabi, gukoresha amashanyarazi adahuye, cyangwa kwirengagiza ibidukikije.
Urwego, Geometrie, na Grip Uburebure: Triad Ntibiganiro
ASTM A325 na A490 byiganje mu byuma byo muri Amerika y'Amajyaruguru; ISO 898-1 Icyiciro cya 8.8 na 10.9 bigenga Uburayi na Aziya. Ariko amanota yonyine avuga kimwe cya kabiri cyinkuru. Icyiciro cya 10.9 Bolt hamwe nu murongo utagabanije gusezerana ntibishobora gufata munsi yikizunguruka-nubwo imbaraga zingana zigenzura impapuro. Dupima uburebure bwa grip-igice kidasomwe gifite umutwaro wogosha - ntabwo ari uburebure bwuzuye. Kuri mm 20 ya diametre ya bolt yometse kuri plaque ya mm 32, gufata byibuze bigomba kuba mm 35. Ntabwo aribyo? Indege zogosha zihinduranya mumutwe. Aho niho hatangirira umunaniro.
Hex umutwe geometrie nayo ifite akamaro. Imitwe isanzwe ya DIN 933 ikorera mu iteraniro rusange - ariko munsi ya preload, impande zose zegeranye zitera impagarara. Abakiriya bacu mumirongo yumuyaga wa turbine bahinduye imitwe iremereye (DIN 6914). Igisubizo: 27% byibanze kumaganya yibanze kuri shank-kumutwe, bigenzurwa no gushushanya ikarita mugihe cyo kugerageza-umutwaro.
Guhitamo ibikoresho bikurikiza ibidukikije, ntabwo bikunzwe. Hot-dip galvanised Grade 8.8 bolts iheruka imyaka 25+ muri zone yinganda. Ibyuma bitagira umwanda 304 bolts byangirika vuba aho - chloride pitingi itsindisha uburinganire bwuzuye. Nyamara mubihingwa bitunganya ibiryo hamwe no gukaraba aside kenshi, gutsindira ingese. Nta bwumvikane. Nta bigufi.
Kwishyiriraho Ntabwo Gukomera-Igenzurwa na Preload
Kunanirwa kwumurima byinshi bibaho nyuma yubushakashatsi - ntabwo mugihe cyo guhimba. Kubera iki? Kuberako imirongo ya torque itagenzura preload. Bagenzura ubushyamirane. Kandi guterana biratandukanye cyane: gusiga amavuta hamwe nudodo twumye, ubunini bwa zinc, ndetse nubushuhe bwibidukikije. Igenzura ryakozwe mu 2023 ryakozwe n’abakozi 14 bo mu Bushinwa bashiraho ibyuma basanze indangagaciro za torque zitandukanye ± 38% kuri mm 24 zisa na A325 - bigatuma 11% byihuza bigabanuka munsi yingufu zisabwa.
Turasaba ibipimo byerekana impagarara (DTIs) kubice byingenzi-cyangwa uburyo bwo guhinduranya-uburyo bwo guhinduranya ibinyomoro kuri RCSC. Kuri Grade 10.9 M24 ya bolts, urutonde rwapimwe na laboratoire ni: gukanda-gufunga (gufatisha ukuboko hiyongereyeho icyerekezo kimwe), hanyuma ukazenguruka neza 270 ° byashize. Ibyo bitanga umusaruro ushimishije 70-75% preload, utitaye kumavuta yo kwisiga cyangwa umunaniro wabakoresha.
Ubuso bwo hejuru ntabwo ari ubushake. Igipimo cy'urusyo ku cyuma fatizo? Gusya. Irangi ryinshi hejuru yisabune? Kuraho. Ikibanza kimwe cyabuze kigabanya ahantu heza hafatirwa kugera kuri 40%. Dutanga ibyuma byose byubatswe hamwe no gukaraba gukomeye guhura na ASTM F436 - ntizigera isimbuza ibyuma byoroshye.
Impamvu Kwishyira hamwe Guhindura Byose
Bamwe mubatanga ibicuruzwa bohereza, hanyuma bagakorana amasezerano. Abandi bakura ibibabi biva mu nsyo eshatu. Gutandukana bitera icyuho cyo gukurikiranwa-no gukora icyuho. Kuri Hebei Dewell, buri Imiterere minini ya hexagonal bolt inyura munzu yacu ishyushye-dip umurongo wa galvanizing. Ubunini bwa Zinc bupimwa na magnetic induction * nyuma yo gukonja - ntibigereranijwe n'ubushyuhe bwo kwiyuhagira. Twinjiza uburemere bwa buri kintu: 610 g / m² byibuze kugirango dukoreshe hanze. Nta na kimwe kidasanzwe.
Laboratwari zacu ebyiri za R&D zemeza buri cyiciro kurwanya imbaraga zidatinze ndetse no gutinda kwa hydrogène yatinze - ni ingenzi cyane kumashanyarazi akomeye ahura nubushyuhe bwo gusudira cyangwa ikirere cya acide. Turagerageza 100% byibyiciro kugirango twubahirize ibipimo: ikosa ryumutwe ≤0.05 mm, kwihanganira uburebure bwumutwe ± 0.2 mm, kugorora shank ≤0.15 mm / m. Ubwo busobanuro butuma abajenjeri bashingira ku gishushanyo mbonera cyatangajwe - ntabwo ari umutekano.
Turagenzura kandi ibikoresho. Sitasiyo yohereza ibicuruzwa kuri site bivuze ko nta gutinda kububiko bwabandi. Kwohereza ibicuruzwa hanze - harimo ibyemezo byubuziranenge kuri ASTM A325 - amato afite ibicuruzwa. Nta kwirukana impapuro. Nta mushinga uhagarara.
Kugenzura Byanyuma Mbere yuko Bolt
Mbere yo gukomera kwanyuma, genzura izi ngingo eshanu kurubuga:
Guhuza amanota: “8.8” cyangwa “A325” byashyizweho kashe ku mutwe - ntabwo biri ku gupakira gusa Emeza uburebure: Gupima shank idasomwe hamwe na calipers, ntabwo uburebure bwizina Kugenzura uburinganire: Nta bibanza byambaye ubusa, ibisebe, cyangwa dinc zirenze urugero kumutwe Reba ubukana bwo gukaraba: Koresha dosiye - niba irumye byoroshye, ujugunye Kwemeza ibikoresho bya kalibibasi: Buri 200 bolts, cyangwa burimunsi - niyo iza mbere Iyo ubonye byose uko ari bitanu, ntabwo uba uteranya ibyuma-uba ufungiye mubunyangamugayo. Hebei Dewell Metal Products Co, LTD yubaka Imiterere minini ya hexts gukora munsi yumutwaro, ntabwo yatsinze igenzura gusa. Ntabwo tugurisha ibifunga. Dutanga imbaraga za clamp ziteganijwe - zishobora gukurikiranwa, kugeragezwa, no kwizerwa mubihugu 30+.
