ISO 7412 ntabwo ari amahame nyayo mpuzamahanga. Ntabwo ibaho muri kataloge ya ISO, ntabwo yigeze isohoka n’umuryango mpuzamahanga ushinzwe ubuziranenge, kandi nta hantu na hamwe igaragara mu bubiko bwemewe nka ISO Online Browsing Platform (OBP) cyangwa IEC Webstore.
Ukuri kwonyine gusobanura impamvu injeniyeri, abashinzwe gutanga amasoko, hamwe nabagenzuzi b'ubuziranenge bahora bananirwa kumenya ISO 7412 ibisobanuro - kuko nta nyandiko nkiyi ibaho. Twabigenzuye muri cheque eshatu zigenga: Kwiyandikisha kwa ISO, inzego zigihugu zigihugu (SAC, DIN, BSI, JIS), hamwe nimyaka mirongo yinganda zihuta. Iyo abakiriya batubajije kuri Hebei Dewell Icyuma Clon Co., Ltd kuri "ISO 7412 ibyemezo byubahirizwa," turahagarara - hanyuma tukanyura mubyo bakeneye mubyukuri.
Urujijo hafi ya buri gihe ruva kuri imwe mu masoko atatu: ibirango byanditse nabi ku byuma by’umurage, kodegisi y’imbere mu gihugu yibeshye ku bipimo mpuzamahanga, cyangwa amakosa y’ubuhinduzi aho “ISO” yashyizwe ku cyerekezo kitari ISO (urugero: uruganda rufite uruganda rufite nimero 7412). Mu rubanza rumwe umwaka ushize, umukiriya w’Uburayi yatwoherereje igishushanyo cyanditseho “ISO 7412 - Shear Pin Diameter Tolerance.” Twambukiranya imbonerahamwe yose yo kwihanganira ibipimo muri ISO 2768, ISO 286, na ISO 1101 - ntaho bihuriye. Ibisobanuro nyabyo byari DIN 7412, ubudage bwahagaritswe kubudodo bwa silindrike - mubyukuri ubwoko bwa Dewell bukora mubyuma bitagira umwanda hamwe nicyuma kivanze na ± 0.005 mm GD&T igenzura.
DIN 7412: Mubyukuri Nukuri (nimpamvu bifite akamaro)
DIN 7412 isobanura ibyangombwa bya tekiniki kubikoresho bya silindrike - byitwa pin ya dowel cyangwa pin ihuza - bikoreshwa mu jigs, ibikoresho, no guterana neza. Nubwo yakuweho mu mwaka wa 2008, iracyavugwa cyane mu bishushanyo mbonera by’imashini, cyane cyane mu binyabiziga bitanga amamodoka n’ikirere mu Budage, Ubuyapani, na Aziya y’Amajyepfo y’Amajyepfo.
Ibyingenzi byingenzi bya tekinike munsi ya DIN 7412 harimo:
Amahitamo y'ibikoresho: C45E ibyuma (bikomye), 1.4301 ibyuma bidafite ingese, cyangwa ibivangwa n'abakiriya Ishuri ryo kwihanganira: h6 kumapine asanzwe; h5 cyangwa h4 kubisobanuro bihanitse Kurangiza: Ra ≤ 0.8 µm kuri zone ikora; kugenzura gukomeye kwuzuye kurwego rwa Rockwell C. Iboneza umutwe: Umutwe uzengurutse, umutwe uringaniye, cyangwa ucuramye - buri kimwe gisobanuwe munsi ya radiyo ninzibacyuho Dutanga DIN 7412 yuzuza pin buri munsi mukigo cyacu cya hegitari 10 muri Yongnian. Buri cyiciro gikora imashini yo gupima (CMM) kwemeza kuri diameter ya pin, kwibanda, hamwe na geometrie - ntabwo ari rimwe gusa, ariko mugitangira, hagati, no kugenzura kwa nyuma. Nuburyo twemeza gusubiramo muri 400+ SKUs, harimo uburebure bwihariye, verisiyo-y-verisiyo, hamwe na PTFE-yashizwemo na progaramu ya friction nkeya.
Kuki "ISO 7412" Ikomeza Kugaragara (n'icyo gukora Ahubwo)
Bamwe mubatanga urutonde "ISO 7412" kurubuga rwa e-ubucuruzi cyangwa kataloge ya PDF nkibisobanuro - byoroshye, ntabwo bisaba kubahiriza. Ariko ibyoroshye bitera ingaruka. Itsinda ryamasoko ritegeka "ISO 7412 bolts" rishobora kwakira ibyuma bitujuje ibisobanuro byemewe. Ibipimo bidahuye, imbaraga zidahwitse, cyangwa kuvura hejuru yubutaka ntibishobora gutera inteko kunanirwa cyangwa kugenzura ibitagenda neza.
Dore gahunda y'ibikorwa byageragejwe mu murima:
Kurikirana inkomoko: Baza igishushanyo cyumwimerere cyangwa nimero yihariye. Niba isoma "ISO 7412", saba urwego rutanga numwaka wo gutangaza. Ibipimo byemewe byerekana ISO, ASTM, DIN, cyangwa GB ibanziriza. Imikorere ihuza, ntabwo ari ikirango: Igice ni pin? Noneho DIN 7412, ISO 2339, cyangwa GB / T 119.1 birakurikizwa. Nibikonoshwa byubatswe? Noneho ASTM F3125 Icyiciro A325 cyangwa GB / T 1231 kiyobora. Kugenzura raporo y'ibizamini. Twabonye abakiriya bazigama iminsi 17-22 mugihe cyo gukora gusa mugusimbuza imvugo "ISO 7412" idasobanutse hamwe no guhamagara tekinike mbere yo gutanga PO.
Uburyo Hebei Dewell Ashyigikira Kwubahiriza Byukuri - Ntabwo ari Ibirango
Kuri Dewell, ntabwo tugurisha ibipimo - dutanga imikorere ikurikirana, yapimwe, yanditse. Amashami yacu abiri ya R&D yihariye mugukemura icyuho kiri hagati yigihe cyashize hamwe nibikorwa byiza bigezweho. Iyo umukiriya yohereje igishushanyo kivuga "ISO 7412", abajenjeri bacu bashushanya ibipimo byose, ibikoresho, no kurangiza ibisabwa kugirango bakore, bishyirwa mu bikorwa - hanyuma babyemeze kubirwanya.
Ibikorwa remezo byacu bifasha ibyo gukomera: munzu ya zinc itwikiriye hamwe na ASTM B633 Icyiciro cya Fe / Zn 5 cyo gupima ruswa, ibigo bitunganya imashini za CNC hamwe nindishyi zumuriro nyazo, hamwe nibyiciro byuzuye biva mumibare yabigenewe kugeza nimibare yohereza hanze.
Kubona pin byumwihariko, turatanga:
Amabati ya poste idafite ibyuma kuri ISO 2339 (metric) cyangwa ANSI B18.8.2 (santimetero) Gukomera ibyuma bisobekeranye hamwe nuburemere 45-50 HRC na ≤0.008 mm Porogaramu ya GD&T yihariye - harimo kwihanganira imyanya kuri datum A-B-C hamwe no kugenzura imyirondoro Inyandiko zuzuye: Icyemezo cyo gukora, raporo ya RoHS / REACH, nicyemezo cyinkomoko Igihe cyo kuyobora? Iminsi 7 kuburugero. Iminsi 15-20 yo gutumiza ibicuruzwa - hamwe na zeru kumvikana kuri verisiyo yo kugenzura cyangwa metallurgical.
Ibipimo birahari kugirango wirinde gutsindwa - kutuzuza impapuro. Kwitiranya "ISO 7412" nibisabwa byubuhanga byukuri bibangamira umutekano, kwiringirwa, no kwizerana. Kuri Dewell, dufata ikibazo cyose cyihariye nkubufatanye: gusobanura intego, kwemeza physics, hanyuma twubake kumibare ifite akamaro. Kuberako iyo pin ishakisha ifata turbine blade cyangwa igahuza moderi ya batiri ya EV, nta mwanya wibirango byabitswe.
Niba umushinga wawe werekana ISO7412, tangira hano: dewellfastener.com. Ba injeniyeri bacu bazamenya neza imikorere ikora - kandi batange ibyuma byujuje, igihe cyose.
