Abamesa ba DIN127 bari mubantu benshi basukuye neza mubukanishi bwuburayi-nyamara bakunze guhitamo nabi, ntibisobanuwe neza, cyangwa bakitiranya na DIN 125 cyangwa ISO 7089. Twabonye inshuro mirongo: umukiriya yohereje icyiciro cyumuyaga mwinshi mukibuga cyumuyaga cyumuyaga mumajyaruguru yubudage-gusa ugasanga aho wasangaga inteko za DIN127 zitangwa zidafite icyiciro gikenewe. Gukosora? Gukora, gutinda, hamwe nibikoresho bidateganijwe. Niyo mpamvu ibintu bisobanutse neza - bitari mubikoresho cyangwa kurangiza gusa, ahubwo byubahirizwa bisanzwe.
Niki Cyukuri DIN127 Yogeje?
Gukaraba DIN127 ni uruziga ruzengurutse, rutarinze gukaraba rwasobanuwe n’ikigo cy’Ubudage gishinzwe ubuziranenge (DIN) DIN 127 Igice cya 1. Igizwe na diameter yo hanze, diameter y'imbere, n'ubugari - ibarwa nk'igikorwa cy'ubunini bwa nomero - kandi yagenewe umwihariko wo gukoresha hamwe n'umutwe wa hexagon hamwe n'imigozi ihuye na DIN 931, DIN 933, cyangwa ISO 4014/4017. Bitandukanye no gukaraba gukomeye (urugero, DIN 6796 cyangwa DIN 2093), ibice DIN127 ntabwo bivura ubushyuhe. Mubisanzwe bitangwa muburyo budafunze, bushyizwemo imbaraga, cyangwa pasitifike ibyuma - kandi uruhare rwabo rwibanze ni ugukwirakwiza imizigo, ntabwo ari ibikorwa byimpeshyi cyangwa gufunga.
Ibintu by'ingenzi bya tekiniki:
Amahitamo y'ibikoresho: Icyuma (kidakomeye, ≤300 HV), ibyuma bitagira umwanda (A2 / A4), umuringa, aluminium Ubuso burarangiye: Ikibaya, gishyushye-gishyushye (HDG), zinc-plaque, oxyde yumukara, amashanyarazi Umupaka ntarengwa: Max 300 HV - ingenzi cyane kugirango ihuze nimbaraga zikomeye (Icyiciro 8.8 no hejuru) Ishuri ryo kwihanganira: Bisanzwe (Urwego N) kuri DIN 2211; kwihanganira umubyimba ± 0.2 mm kuri d ≤ 16 mm Ubwoko butatu-Bwisi DIN127 Ubwoko-N'aho Batsinzwe
Mu myitozo, dushyira DIN127 yogeje mubyiciro bitatu byimikorere - ntabwo byujuje ubuziranenge, ahubwo nukuntu abajenjeri babyohereza.
Ubwoko A: Gukaraba Flat isanzwe (DIN127-A)
Mburabuzi. Ikoreshwa hamwe na bolts kugeza mucyiciro cya 8.8 mumashini rusange, ibikoresho byubuhinzi, hamwe nuburyo bwo murugo. Turabisaba mugihe umuvuduko wubutaka ugomba kugabanuka munsi yimitwe ya bolt - ariko ntagikorwa cyo gupakira cyangwa kunyeganyega giteganijwe.
Ubwoko B: HDG-DIN127 kubwubatsi bwo hanze
Amashanyarazi ashyushye ya DIN127 yogeje bisaba kwitabwaho bidasanzwe. Ipitingi ya Zinc yongeraho ~ 0,05-0,10 mm kubyimbye-kandi niba itabaruwe mugihe cyo kubara umuriro, imbaraga zo gufata zigabanukaho 8-12%. Ku kigo cyacu muri Yongnian, turagenzura uburebure bwa coating dukoresheje induction (DIN EN ISO 2178) mbere yo koherezwa. Abakiriya bakoresha ibi hamwe na ASTM A325 ya bolts muguhuza ikiraro bahora batangaza ko zeru zeru mugihe cyimyaka 5 ya serivise.
Andika C: DIN127 idafite umwanda kubidukikije byangirika
A4-80 ibyuma bitagira umwanda DIN127 yoza (kuri DIN 127-2) irwanya spray yumunyu> amasaha 1.000. Ariko dore ibyo bikunze kubura: gukaraba bitagira umwanda byagura ubushyuhe bwa 30% kuruta ibyuma bya karubone. Mubikorwa byo gusiganwa ku magare yubushyuhe-nkumurongo wizuba ukurikirana mubihe byubutayu-twabonye igihombo cyo guhunika gasketi mugihe abayikoresha basibye gusiba. Igisubizo cyacu? Hindura A4-80 DIN127 hamwe na A4-80 bolts - hanyuma ugaragaze indangagaciro za torque mubushyuhe bwo gukora, ntabwo ari ibidukikije.
Kuringaniza Ntabwo ari "M6" cyangwa "M12" -Ni Sisitemu
Ingano ya DIN127 ikurikira igipimo cya geometrike - ntabwo ari diameter. Kuri bolt ya M10 (d = 10 mm), diameter y'imbere yogeje ni 11.1 mm, diameter yo hanze ni mm 22, n'ubugari ni mm 2,5. Gutandukana n'izo ndangagaciro, kandi ushobora guhura n'ingaruka zo kurumwa, kwimura umutwaro utaringaniye, cyangwa kwivanga no guhuza imigozi.
Turabika DIN127 yuzuye kuva M3 kugeza M64 - harimo metric coarse hamwe nududodo twiza - kandi twemeza buri kintu cyose kurwanya cheque ya DIN 2211. Ubugenzuzi busanzwe dufata buri munsi:
Ukoresheje M12 DIN127 hamwe na M12x1.25 nziza-umugozi mwiza (diameter y'imbere idahuye → umutwe wumutwe uhuza amanota 3 gusa) Gusimbuza DIN125 (kubyimbye, gukomera) aho DIN127 yerekanwe (itera kurenza urugero-kwambura umugozi) Dufate ko “DIN127” bisobanura kurwanya ruswa - iyo verisiyo ya karubone isanzwe yangirika mu byumweru byinshi mu kirere cyo ku nkombe. Porogaramu Zisaba DIN127-Kandi Impamvu Ibindi Bigufi
DIN127 ntabwo ihitamo mubice bine bikomeye:
Icyuma cyubaka . Gariyamoshi . Offshore platform module : Ibikoresho byo kwa muganga . Gukaraba Wave cyangwa Bellevilles ntibizasimbura DIN127 hano. Bakorera physics zitandukanye: DIN127 icunga static ihangayikishije. Abandi bayobora igihombo cya preload. Kubitiranya ni nko gukoresha umugozi nk'inyundo - birashoboka, ariko birasenya.
Impamvu Hebei Dewell Itanga DIN127 Yizewe
Muri Hebei Dewell Metal Products Co, LTD, dukora ibikoresho byogeje DIN127 bigenzurwa byuzuye - kuva kugenzura ibibari mbisi (isesengura rya sprometrike kuri DIN EN ISO 14284) kugeza ibyemezo byanyuma. Buri cyiciro kirimo imibare yubushyuhe ikurikirana, raporo yikizamini cya tensile, hamwe no kugenzura uburebure. Dufite ibarura muri variant 12 DIN127-zirimo HDG, A2, A4, hamwe nubunini-bwihariye-hamwe nubunini busanzwe bwoherejwe muminsi 5-10 kwisi yose.
Niba urimo kwerekana DIN127 kumushinga mushya: banza ugenzure urwego rwa bolt, ibidukikije, nuburyo bwa torque. Noneho uhuze gukaraba gukomeye, kurangiza, na geometrie - ntabwo ari label gusa. Kuberako muburinganire bwubukanishi, igice gito gishyiraho igisenge cyo gukora sisitemu.
