DIN127 washers ari pakati peanonyanya kutsanangurwa flat washers muEuropean mechanical engineering — asi anogaro sarudzwa, asina kutaurwa, kana kuvhiringika neDIN 125 kana ISO 7089. washer anopihwa anoshaya giredhi rekuomarara rinodiwa pamagungano eGrade 10.9. Kugadzirisa? Rework, kunonoka, uye zvisina kurongwa Logistics. Ndicho chikonzero nei kurongeka kunokosha-kwete chete muzvinhu kana kupedza, asi mukuteerera kwakajairwa.
Chii Chaizvo Chinonzi DIN127 Washer?
DIN127 washer idenderedzwa, isina kuomeswa flat washer inotsanangurwa neGerman Institute for Standardization (DIN) chiyero. DIN 127 Chikamu chekutanga. Iyo ine dhayamita yekunze chaiyo, dhayamita yemukati, uye ukobvu-inoverengerwa sebasa rezita rebhaudhi saizi-uye yakagadzirirwa chaizvo kushandiswa nehexagon head mabhaudhi uye screws zvinoenderana neDIN 931, DIN 933, kana ISO 4014/4017. Kusiyana neakaomeswa washers (semuenzaniso, DIN 6796 kana DIN 2093), DIN127 mayunitsi haabatike kupisa. Iwo anowanzo kupihwa asina kuvharwa, galvanized, kana passivated stainless mafomu-uye basa ravo rekutanga kugovera mitoro, kwete muchirimo chiitiko kana kukiya.
Makiyi ehunyanzvi maitiro:
Zvinhu zvingasarudzwa: Simbi (isina kuomeswa, ≤300 HV), simbi isina tsvina (A2/A4), ndarira, aluminium Surface inopera: Yakajeka, inopisa-yakanyungudutswa yakavhenekerwa (HDG), zinc-plated, black oxide, electropolished Kuoma muganhu: Max 300 HV—yakakosha kuti ienderane nezvisungo zvine simba guru (Giredhi 8.8 zvichikwira) Kuuraya Kirasi: Zvakajairika (Kirasi N) paDIN 2211; ukobvu kushivirira ± 0.2 mm nokuda d ≤ 16 mm Matatu Chaiwo-Nyika DIN127 Mhando-uye Kwaanokundikana
Mukuita, isu tinounganidza DIN127 washers muzvikamu zvitatu zvinoshanda-kwete nezviri pasi pemutemo, asi nemashandisirwo anoitwa mainjiniya.
Type A: Standard Flat Washers (DIN127-A)
The default version. Inoshandiswa nemabhaudhi anosvika Grade 8.8 mune zvakajairika muchina, midziyo yekurima, uye indoor structural frameming. Isu tinokurudzira izvi kana kudzvinyirirwa kwepamusoro kuchifanira kudzikiswa pasi pemisoro yebhaudhi-asi hapana kurodha kana kuzunguzika kunotarisirwa.
Rudzi B: HDG-DIN127 yeInjiniya Yekunze
Hot-dip galvanized DIN127 washers inoda kutariswa kwakakosha. Zinc coating inowedzera ~ 0.05-0.10 mm kune ukobvu-uye kana ikasaverengerwa panguva yekuverenga torque, clamping simba inodonha ne8-12%. Panzvimbo yedu muYongnian, tinosimbisa ukobvu hwekuvhara kuburikidza nemagineti induction (DIN EN ISO 2178) isati yatumirwa. Vatengi vanoshandisa aya neASTM A325 mabhaudhi mukubatanidza mabhiriji vanogara vachishuma zero kusunungurwa pamusoro pemakore mashanu ekutenderera sevhisi.
Type C: Stainless DIN127 yeCorrosive Environments
A4-80 Stainless steel DIN127 washers (paDIN 127-2) ramba munyu pfapfaidzo kwe>1,000 maawa. Asi hezvino izvo zvinowanzoshaikwa: mawachi asina tsvina anowedzera thermally 30% kupfuura kabhoni simbi mabhoti. Mukupisa kwekushandisa bhasikoro - senge solar tracker inokwira mumamiriro ekunze erenje - takaona gasket compression kurasikirwa kana vashandisi vakasvetuka kupisa kupisa. Mhinduro yedu? Pair A4-80 DIN127 ine A4-80 mabhaudhi-uye tsanangura kukosha kwe torque patembiricha yekushanda, kwete ambient.
Kukura Haisi Ingori "M6" kana "M12" -Iyo Sisitimu
DIN127 saizi inoteedzera zvakaomesesa geometric reshiyo-kwete madhayamita asingaite. PaM10 bhaudhi (d = 10 mm), washer dhayamita yemukati i11.1 mm, dhayamita rekunze 22 mm, uye ukobvu i2.5 mm. Tsauka kubva kune izvo zvakakosha, uye iwe unoisa panjodzi yekuruma, kusaenzana kutakurwa kwemutoro, kana kuvhiringidzwa netambo yekubatana.
Isu tinochengetedza yakazara DIN127 stock kubva kuM3 kusvika kuM64-kusanganisira metric yakakoshera uye yakanaka shinda-uye kusimbisa mijenya yese inopesana neDIN 2211 dimensional cheki. Maonero akajairika atinobata zuva nezuva:
Kushandisa M12 DIN127 ine M12x1.25 yakanaka-tambo mabhaudhi (yemukati dhayamita kusapindirana → bhaudhi musoro kubata chete pamapoinzi matatu) Kutsiva DIN125 (yakakora, yakaomeswa) apo DIN127 inotsanangurwa (inokonzeresa kuwanda-torque uye kubviswa kweshinda) Kufungidzira kuti "DIN127" inoreva kuramba kwecorrosion-apo mavhezheni akajeka kabhoni anoita ngura mukati memavhiki mumhepo yemahombekombe. Zvishandiso Zvinoda DIN127-Uye Nei Dzimwe Nzira Dzichiderera
DIN127 haisi yekusarudzika mumatunhu mana akakosha:
Steal Steel kubatana (TS EN 1090-2): Inodiwa pasi peEurocode 3 kune mabhaudhi majoini apo washer anodzivirira kunyura munzvimbo dzeflange. Railway rolling stock ( EN 15227): Inosungirwa kukwirisa mota - isingaenderane washers inokonzeresa kutadza kwekuongorora. Offshore platform modules (DNV-OS-F101): Inofanirwa kuenzanisa kuomarara kwebhaudhi kudzivirira hydrogen-induced kupaza mubasa rakavava Mafuremu emidziyo yekurapa (ISO 13485): Kupera kwepamusoro Ra ≤ 0.8 µm inodiwa-DIN127-A4 inosangana neizvi pasina kupenya kwechipiri. Wave washer kana Bellevilles haizotsiva DIN127 pano. Vanoshumira zvakasiyana fizikisi: DIN127 inogadzirisa static kutakura kushushikana. Vamwe vanobata dynamic preload kurasikirwa. Kuvavhiringa kwakafanana nekushandisa chipanera sesando—zvinobvira, asi zvinoparadza.
Nei Hebei Dewell Achiendesa Akavimbika DIN127 Washers
KuHebei Dewell Metal Products Co., LTD, tinogadzira madhiri eDIN127 pasi pekutonga kwakazara-kubva pawongororo yebhawa (spectrometric analysis per DIN EN ISO 14284) kusvika kumagumo ekupedzisira etifiketi. Kurongeka kwega kwega kunosanganisira nhamba dzekupisa dzinotevedzwa, tensile bvunzo mishumo, uye coating ukobvu verification. Isu tinobata hesitori pane gumi nemaviri DIN127 akasiyana-kusanganisira HDG, A2, A4, uye tsika-kukora sarudzo-uye ngarava saizi yakajairwa mumazuva mashanu-10 pasi rose.
Kana iwe uchitsanangura DIN127 yepurojekiti nyowani: tarisa yako bhaudhi giredhi, nharaunda, uye torque nzira kutanga. Wobva wafananidza kuomarara kwewasher, kupedzisa, uye geometry-kwete chete iyo label. Nekuti mukutendeseka kwemuchina, chikamu chidiki diki chinoseta sirin'i yekuita system.
