Makina ochapira a DIN127 ali m'gulu la machacha athyathyathya omwe amatchulidwa kwambiri muukadaulo wamakina waku Europe-koma samasankhidwa molakwika, sadziwika, kapena amasokonezedwa ndi DIN 125 kapena ISO 7089. makina ochapira omwe amaperekedwa alibe giredi yolimba yofunikira pamisonkhano ya Giredi 10.9. Kukonza? Kukonzanso, kuchedwetsa, ndi mayendedwe osakonzekera. Ndicho chifukwa chake kulondola kuli kofunika—osati kokha m’zinthu zakuthupi kapena kutsirizitsa, koma m’kutsatiridwa kokhazikika.
Kodi DIN127 Washer Ndi Chiyani Kwenikweni?
Wochapira wa DIN127 ndi chozungulira, chosalimba chathyathyathya chotanthauziridwa ndi muyezo wa Germany Institute for Standardization (DIN) DIN 127 Gawo 1. Imakhala ndi mainchesi akunja, m'mimba mwake, komanso makulidwe ake, omwe amawerengedwa ngati kukula kwake kwa bawuti, ndipo idapangidwa kuti igwiritsidwe ntchito ndi mabawuti amutu ndi zomangira za hexagon zomwe zimagwirizana ndi DIN 931, DIN 933, kapena ISO 4014/4017. Mosiyana ndi makina ochapira olimba (mwachitsanzo, DIN 6796 kapena DIN 2093), mayunitsi a DIN127 samatenthedwa. Nthawi zambiri amaperekedwa ngati zitsulo zosapanga dzimbiri zosatsekedwa, malata, kapena zitsulo zosapanga dzimbiri—ndipo ntchito yawo yaikulu ndi kugawa katundu, osati kuchita masika kapena kutseka.
Zofunikira zaukadaulo:
Zosankha zakuthupi: Chitsulo (chosalimba, ≤300 HV), chitsulo chosapanga dzimbiri (A2/A4), mkuwa, aluminiyamu Pamwamba amamaliza: Wamba, otentha-kuviika kanasonkhezereka (HDG), zinc-yokutidwa, wakuda okusayidi, electropolished Kuuma malire: Max 300 HV—yofunikira kuti igwirizane ndi zomangira zamphamvu kwambiri (Giredi 8.8 ndi kupitilira apo) Gulu la kulolerana: Normal (Kalasi N) pa DIN 2211; kulekerera makulidwe ± 0.2 mm kwa d ≤ 16 mm Mitundu itatu ya Real-World DIN127-ndipo Imalephera
M'malo mwake, timagawa ma washer a DIN127 m'magulu atatu ogwira ntchito-osati motengera momwe amagwirira ntchito, koma momwe mainjiniya amawatumizira.
Mtundu A: Ma Washers Okhazikika (DIN127-A)
Mtundu wokhazikika. Amagwiritsidwa ntchito ndi mabawuti mpaka Giredi 8.8 pamakina wamba, zida zaulimi, ndi zomangamanga zamkati. Timalimbikitsa izi pamene kuthamanga kwa pamwamba kuyenera kuchepetsedwa pansi pa mitu ya bawuti-koma palibe kukweza kapena kugwedezeka komwe kumayembekezeredwa.
Mtundu B: HDG-DIN127 ya Umisiri Wakunja
Mawotchi otentha a DIN127 amafunikira chisamaliro chapadera. Kupaka kwa zinc kumawonjezera ~ 0.05-0.10 mm kukhuthala - ndipo ngati sikunawerengedwe panthawi yowerengera torque, mphamvu yothina imatsika ndi 8-12%. Pamalo athu ku Yongnian, timatsimikizira makulidwe a zokutira pogwiritsa ntchito maginito induction (DIN EN ISO 2178) tisanatumize. Makasitomala omwe amagwiritsa ntchito mabawuti a ASTM A325 pamalumikizidwe amilatho nthawi zonse amafotokoza kuti palibe kumasuka kwa zaka zisanu.
Mtundu C: Stainless DIN127 wa Malo Owononga
A4-80 zitsulo zosapanga dzimbiri DIN127 washers (pa DIN 127-2) amakana kutsitsi mchere kwa > 1,000 maola. Koma izi ndi zomwe nthawi zambiri zimaphonya: zochapira zosapanga dzimbiri zimakulitsa thermally 30% kuposa ma bolts a carbon steel. M'machitidwe oyendetsa njinga otentha - monga kukwera kwa solar tracker m'malo achipululu - tawona kutayika kwa gasket pomwe ogwiritsa ntchito adumpha kutenthetsa. Yankho lathu? Gwirizanitsani A4-80 DIN127 yokhala ndi mabawuti A4-80—ndipo tchulani ma torque pa kutentha kwa ntchito, osati mozungulira.
Kukula Sikuti "M6" Kapena "M12" -Ndi Dongosolo
Kukula kwa DIN127 kumatsata miyeso yolimba ya geometric - osati ma diameter okhazikika. Kwa bawuti ya M10 (d = 10 mm), m'mimba mwake wa washer ndi 11.1 mm, m'mimba mwake ndi 22 mm, ndipo makulidwe ake ndi 2.5 mm. Patukani pazikhalidwezi, ndipo mungakhale pachiwopsezo cha kulumidwa, kusamutsa katundu mosiyanasiyana, kapena kusokoneza kulumikizana ndi ulusi.
Timasunga zinthu zonse za DIN127 kuchokera ku M3 mpaka M64—kuphatikiza ulusi wowoneka bwino komanso wowoneka bwino—ndikutsimikizira macheke aliwonse motsutsana ndi macheke a DIN 2211. Zotsatira zoyipa zomwe timapeza tsiku lililonse:
Kugwiritsa ntchito M12 DIN127 yokhala ndi ma bawuti a ulusi wa M12x1.25 (kusagwirizana kwamkati mkati → kukhudzana ndi mutu wa bawuti pokhapokha pamfundo zitatu) Kulowetsa DIN125 (yowuma, yowumitsidwa) pomwe DIN127 yatchulidwa (kumayambitsa ma torque mopitilira muyeso ndi kudulidwa kwa ulusi) Kungoganiza kuti "DIN127" ikutanthauza kukana dzimbiri-pamene matembenuzidwe amtundu wa kaboni achita dzimbiri mkati mwa milungu ingapo mumlengalenga. Mapulogalamu Amene Amafuna DIN127-Ndi Chifukwa Chake Njira Zina Zimachepa
DIN127 siyosankha m'magawo anayi ovuta:
Malumikizidwe zitsulo zomangamanga TS EN 1090-2: Zofunikira pansi pa Eurocode 3 pamalumikizidwe omangika pomwe ma ma washer amalepheretsa kulowa m'malo a flange. Sitima zapamtunda TS EN 15227: Zoyimitsidwa pakuyika ma motor traction - ma washer osagwirizana amayambitsa kulephera kwa kafukufuku. Offshore platform modules (DNV-OS-F101): Iyenera kufanana ndi kulimba kwa bawuti kuti mupewe kuwonongeka kwa hydrogen muutumiki wowawasa Mafelemu a zida zamankhwala (ISO 13485): Kumaliza pamwamba Ra ≤ 0.8 µm yofunikira—DIN127-A4 imakwaniritsa izi popanda kupukuta kwachiwiri Mawawa ochapira kapena Bellevilles sangalowe m'malo mwa DIN127 pano. Amatumikira mafizikiki osiyanasiyana: DIN127 imayendetsa kupsinjika kokhazikika. Ena amayang'anira kutayika kwamphamvu kowonjezera. Kuwasokoneza kuli ngati kugwiritsira ntchito wrench ngati nyundo—ndizotheka, koma zowononga.
Chifukwa Chake Hebei Dewell Amapereka Ma washer Odalirika a DIN127
Ku Hebei Dewell Metal Products Co., LTD, timapanga makina ochapira a DIN127 omwe amawongoleredwa - kuchokera pakuwunika kwa mipiringidzo yaiwisi (kusanthula kwa spectrometric pa DIN EN ISO 14284) mpaka chiphaso chomaliza cha dimensional. Dongosolo lililonse limaphatikizapo manambala a kutentha, malipoti oyeserera, ndi kutsimikizira makulidwe a zokutira. Tili ndi zida pamitundu 12 ya DIN127, kuphatikiza HDG, A2, A4, ndi makulidwe ake - ndikutumiza kukula kwake masiku 5 mpaka 10 padziko lonse lapansi.
Ngati mukutchula DIN127 ya pulojekiti yatsopano: yang'anani kalasi yanu ya bawuti, malo, ndi njira ya torque kaye. Kenako fananitsani kuuma kwa washer, kumaliza, ndi geometry - osati chizindikiro chokha. Chifukwa mu umphumphu wamakina, gawo laling'ono kwambiri limayika denga la magwiridwe antchito.
