DIN127 cov tshuab ntxhua khaub ncaws yog ib qho ntawm cov tshuab ntxhua khaub ncaws ntau tshaj plaws nyob rau hauv European mechanical engineering-tab sis lawv niaj hnub tsis raug xaiv, tsis muaj kev qhia tshwj xeeb, lossis tsis meej pem nrog DIN 125 lossis ISO 7089. Peb tau pom nws ntau zaus: tus neeg siv khoom thauj khoom ntau lub zog bolts rau lub tshuab cua turbine7 nyob rau sab qaum teb ntawm lub teb chaws Yelemees. tsis muaj qhov yuav tsum tau hardness qib rau Qib 10.9 sib dhos. Qhov kho? Rov ua dua, ncua sijhawm, thiab tsis npaj thauj khoom. Tias yog vim li cas precision tseem ceeb - tsis yog nyob rau hauv cov khoom los yog tag nrho, tab sis nyob rau hauv tus qauv ua raws.
Dab tsi yog DIN127 Washer?
Lub tshuab ntxhua khaub ncaws DIN127 yog lub voj voog, tsis muaj lub tshuab ntxhua khaub ncaws uas txhais los ntawm German Institute for Standardization (DIN) tus qauv DIN 127 Part 1. Nws nta ib txoj kab uas hla, puab txoj kab uas hla, thiab thickness - xam raws li ib tug muaj nuj nqi ntawm nominal bolt loj - thiab yog tsim tshwj xeeb rau siv nrog hexagon taub hau bolts thiab screws raws li DIN 931, DIN 933, los yog ISO 4014/4017. Tsis zoo li cov tshuab ntxhua khaub ncaws tawv (piv txwv li, DIN 6796 lossis DIN 2093), DIN127 units tsis kho cua sov. Lawv feem ntau muab rau hauv cov ntawv tsis muaj coated, galvanized, lossis passivated stainless hlau cov ntaub ntawv - thiab lawv lub luag haujlwm tseem ceeb yog thauj khoom faib, tsis yog caij nplooj ntoos hlav los yog xauv.
Cov yam ntxwv tseem ceeb technical:
Cov khoom siv xaiv: Hlau (tsis muaj zog, ≤300 HV), stainless hlau (A2 / A4), tooj dag, txhuas Nto tiav: Plain, kub-dip galvanized (HDG), zinc-plated, dub oxide, electropolished Hardness txwv: Max 300 HV - qhov tseem ceeb rau kev sib raug zoo nrog lub zog siab (Qib 8.8 thiab siab dua) Chav kawm kam rau ua: Ib txwm (Class N) rau DIN 2211; thickness kam rau ua ± 0.2 hli rau d ≤ 16 hli Peb Lub Ntiaj Teb Tiag DIN127 Hom-thiab Qhov Lawv Ua Tsis Tau
Hauv kev xyaum, peb pab pawg DIN127 cov tshuab ntxhua khaub ncaws rau hauv peb pawg ua haujlwm - tsis yog los ntawm kev ua haujlwm tsis zoo, tab sis los ntawm kev siv cov engineers siv lawv li cas.
Hom A: Standard Flat Washers (DIN127-A)
Lub neej ntawd version. Siv nrog bolts mus txog qib 8.8 hauv cov tshuab dav dav, cov khoom siv ua liaj ua teb, thiab cov txheej txheem sab hauv tsev. Peb pom zoo kom cov no thaum lub siab saum npoo yuav tsum tau txo qis hauv qab lub taub hau taub hau - tab sis tsis muaj kev thauj khoom dynamic lossis kev vibration.
Hom B: HDG-DIN127 rau Sab Nraud Engineering
Kub-dip galvanized DIN127 ntxhua khaub ncaws yuav tsum tau saib xyuas tshwj xeeb. Zinc txheej ntxiv ~ 0.05-0.10 hli rau thickness - thiab yog tias tsis suav rau thaum lub sij hawm torque xam, clamping quab yuam poob los ntawm 8-12%. Ntawm peb qhov chaw nyob hauv Yongnian, peb txheeb xyuas cov txheej tuab ntawm kev sib nqus induction (DIN EN ISO 2178) ua ntej khoom xa tuaj. Cov neeg siv khoom siv cov no nrog ASTM A325 bolts hauv kev sib txuas txuas txuas txuas txuas ntxiv qhia xoom xoob xoob dhau 5 xyoo kev pabcuam.
Hom C: Stainless DIN127 rau Corrosive Ib puag ncig
A4-80 stainless hlau DIN127 ntxhua khaub ncaws (ib DIN 127-2) tiv thaiv ntsev tsuag rau> 1,000 teev. Tab sis ntawm no yog dab tsi feem ntau tsis nco qab: stainless washers nthuav thermally 30% ntau dua li carbon steel bolts. Hauv kev siv thermal cycling-zoo li hnub ci tracker mounts nyob rau hauv suab puam huab cua-peb tau pom gasket compression poob thaum cov neeg siv hla thermal derating. Peb qhov kev daws teeb meem? Pair A4-80 DIN127 nrog A4-80 bolts - thiab qhia qhov tseem ceeb torque ntawm kev khiav hauj lwm kub, tsis ambient.
Qhov loj me tsis yog "M6" lossis "M12" - Nws yog qhov System
DIN127 sizing raws li nruj geometric ratios - tsis arbitrary diameters. Rau M10 ntsia liaj qhov rooj (d = 10 hli), lub tshuab ntxhua khaub ncaws sab hauv yog 11.1 hli, sab nraud yog 22 hli, thiab tuab yog 2.5 hli. Deviate los ntawm cov nqi no, thiab koj yuav muaj kev pheej hmoo ntawm ntug tom, tsis sib xws load hloov, los yog cuam tshuam nrog xov kev koom tes.
Peb tuav tag nrho DIN127 Tshuag los ntawm M3 txog M64-xws li metric ntxhib thiab zoo threads-thiab validate txhua ntau tiv thaiv DIN 2211 seem checks. Kev saib xyuas ib txwm peb ntes txhua hnub:
Siv M12 DIN127 nrog M12x1.25 nplua-xov bolts ( puab txoj kab uas hla tsis sib xws → ntsia liaj qhov rooj taub hau tsuas yog 3 ntsiab lus) Hloov DIN125 (thicker, hardened) qhov twg DIN127 tau teev tseg (ua rau over-torque thiab xov stripping) Piv txwv tias "DIN127" hais txog kev tiv thaiv corrosion-thaum cov pa roj carbon monoxide dawb xeb tsis pub dhau lub lis piam hauv huab cua hauv ntug dej hiav txwv Cov ntawv thov uas xav tau DIN127-Thiab yog vim li cas lwm txoj kev poob qis
DIN127 tsis yog xaiv tau hauv plaub qhov tseem ceeb:
Cov Qauv Hlau Sib Txuas TS EN 1090-2: Yuav tsum muaj nyob rau hauv Eurocode 3 rau cov pob qij txha bolted qhov chaw ntxhua khaub ncaws tiv thaiv embedment rau hauv qhov chaw flange Railway rolling Tshuag TS EN 15227 Kev txiav txim siab rau lub cev muaj zog mounting - tsis ua raws li cov tshuab ntxhua khaub ncaws ua rau kev kuaj xyuas tsis ua haujlwm Offshore platform modules (DNV-OS-F101): Yuav tsum ua kom muaj zog bolt kom tsis txhob muaj hydrogen-induced cracking hauv kev pabcuam qaub Cov cuab yeej kho mob thav duab (ISO 13485): Nto tiav Ra ≤ 0.8 µm yuav tsum tau-DIN127-A4 ua tau raws li qhov no yam tsis muaj kev polishing thib ob Wave washers lossis Bellevilles yuav tsis hloov DIN127 ntawm no. Lawv ua haujlwm txawv physics: DIN127 tswj cov kabmob zoo li qub. Lwm tus tswj dynamic preload poob. Tsis meej pem lawv zoo li siv tus ciaj ntswj ua rauj - ua tau, tab sis kev puas tsuaj.
Vim li cas Hebei Dewell xa tuaj yeem ntseeg tau DIN127 Washers
Ntawm Hebei Dewell Hlau Khoom Co., LTD, peb tsim DIN127 washers nyob rau hauv tag nrho cov txheej txheem tswj-los ntawm raw bar tshuaj ntsuam (spectrometric tsom xam rau DIN EN ISO 14284) mus rau qhov kawg seem ntawv pov thawj. Txhua qhov kev txiav txim suav nrog cov lej ntsuas cua sov, cov ntawv ceeb toom kev ntsuas tensile, thiab kev txheeb xyuas qhov tuab tuab. Peb tuav cov khoom muag thoob plaws 12 DIN127 ntau yam-xws li HDG, A2, A4, thiab kev cai-thickness xaiv-thiab cov qauv nkoj loj hauv 5-10 hnub thoob ntiaj teb.
Yog tias koj tab tom teev DIN127 rau ib txoj haujlwm tshiab: xyuas koj cov qib bolt, ib puag ncig, thiab torque txoj kev ua ntej. Tom qab ntawd phim lub tshuab ntxhua khaub ncaws, ua kom tiav, thiab geometry - tsis yog daim ntawv lo. Vim hais tias nyob rau hauv txhua yam kev ncaj ncees, qhov tsawg tshaj plaws yog teem lub qab nthab rau kev ua tau zoo system.
