ISO 7412 haisi chiyero chepasi rose. Iyo haipo mune ISO catalogue, haina kumbobvira yaburitswa neInternational Organisation for Standardization, uye hapana kwainooneka mumadhatabheti epamutemo seISO Online Browsing Platform (OBP) kana IEC Webstore.
Icho chokwadi chega chinotsanangura kuti nei mainjiniya, maneja ekutenga zvinhu, uye maodhita emhando yepamusoro vachiramba vachitadza kuwana ISO 7412 zvakatemwa - nekuti hapana gwaro rakadaro. Takasimbisa izvi pamacheki matatu akazvimirira: Kunyoreswa zviri pamutemo kweISO, masangano epasi rose (SAC, DIN, BSI, JIS), uye makumi emakore ezvinyorwa zveindasitiri zvinokurumidza. Kana vatengi vakatibvunza pa Hebei dewell simbi zvigadzirwa co., ltd ye "ISO 7412 zvitupa zvekuteerera," tinombomira - tobva tafamba navo mune zvavanoda chaizvo.
Kuvhiringika kwacho kunogara kuchidzokera kune chimwe chezvitatu zvinoti: mavara asina kudhindwa pamidziyo yenhaka, makodhi ekambani emukati akakanganiswa nemaitiro epasi rese, kana kukanganisa kweshanduro uko "ISO" yakanamirwa kune isiri-ISO spec (semuenzaniso, chiyero chefekitori chine nhamba 7412). Mune imwe nyaya gore rapfuura, mutengi wekuEurope akatitumira mufananidzo wakanyorwa "ISO 7412 - Shear Pin Diameter Tolerance." Isu takayambuka-references yega yega dimensional kushivirira tafura mu ISO 2768, ISO 286, uye ISO 1101 - hapana inofananidzwa. Reference chaiyo yaive DIN 7412, chiyero cheGerman chakaregwa checylindrical locating pini - chaizvo mhando yeDewell inogadzira musimbi isina tsvina uye alloy simbi ine ± 0.005 mm GD&T control.
DIN 7412: Chii Chaizvo (uye Nei Zvichikosha)
DIN 7412 inotsanangura zvinodiwa zvetekinoroji zvecylindrical ekutsvaga mapini - anonziwo dowel pini kana alignment pini - anoshandiswa mujigs, zvigadziriso, uye nemagungano chaiwo. Kunyangwe yakabviswa muna 2008, inoramba ichitaurwa zvakanyanya mumakina ekudhirowa, kunyanya mumaketani ekupa mota uye aerospace kuGermany, Japan, neSoutheast Asia.
Yakakosha tekinoroji paramita pasi peDIN 7412 inosanganisira:
Zvinhu zvingasarudzwa: C45E simbi (yakaomeswa), 1.4301 simbi isina tsvina, kana mutengi-anotsanangurwa alloys Kuuraya Kirasi: h6 yemapini akajairika; h5 kana h4 yemhando yepamusoro-chaiyo Kumusoro Kupedzisa: Ra ≤ 0.8 µm yenzvimbo dzinoshanda; kuzere kuomarara kwechokwadi pachiyero cheRockwell C Musoro configuration: Musoro wakatenderera, musoro wakatsetseka, kana chamfered - imwe neimwe ine yakatsanangurwa undercut uye transition radii Isu tinogadzira DIN 7412-inoenderana mapini zuva nezuva panzvimbo yedu yemaeka gumi muYongnian. Batch yega yega inobata muchina wekuyeresa (CMM) kusimbiswa padhayamita yepini, concentricity, uye musoro geometry - kwete kamwe chete, asi pakutanga-kumusoro, pakati-kumhanya, uye yekupedzisira kuongorora. Ndiwo maitiro atinovimbisa kudzokorora mukati me400+ SKUs, kusanganisira hurefu hwetsika, shinda-mushanduro, uye PTFE-yakavharidzirwa akasiyana ezvishandiso zvakaderera.
Nei "ISO 7412" Inoramba Ichioneka (uye Zvekuita Pane kudaro)
Vamwe vatengesi vanonyora "ISO 7412" pamapuratifomu e-commerce kana zvinyorwa zvePDF seshorthand - zviri nyore, kwete zvekuteerera. Asi kurerukirwa kunogadzira njodzi. Chikwata chekutenga chinoodha "ISO 7412 mabhaudhi" chinogona kugamuchira Hardware inosangana nezvisingazivikanwe zvakatemwa. Dimensional mismatch, simba rekusimba risiri iro, kana kurapwa kusati kwasimbiswa kunogona kukonzeresa kutadza kwegungano kana kusawirirana kwekuongorora.
Heino hurongwa hwedu hwekuita hwakaedzwa mumunda:
Tsvaga kwakabva: Bvunza iyo yekutanga kudhirowa kana yakatarwa nhamba. Kana ichiverenga "ISO 7412", kumbira boka rinoburitsa uye gore rekuburitsa. Zviyero zviri pamutemo zvinodudza ISO, ASTM, DIN, kana GB prefixes nenzira kwayo. Mechi basa, kwete zita: Chikamu ipini yekutsvaga? Ipapo DIN 7412, ISO 2339, kana GB/T 119.1 inoshanda. Ibhaudhi rekucheka here? Ipapo ASTM F3125 Giredhi A325 kana GB/T 1231 inotonga. Verify test report: Demand mill test report inoratidza simba rekusimba chairo (e.g., 8.8 = 800 MPa min tensile, 640 MPa min goho), hurema hunokosha, uye mibairo yekupfapfaidza munyu - kwete bhokisi rakadhindwa "ISO 7412". Isu takaona vatengi vachichengetedza mazuva gumi nemanomwe kusvika makumi maviri nemaviri munguva yekudzokorora nekungotsiva mutauro we "ISO 7412" usinganzwisisike nehunyanzvi hwekudaidzira PO isati yaburitswa.
Hebei Dewell Anotsigira Sei Kuteerera Kwechokwadi - Kwete Mazita
KuDewell, isu hatitengesi zviyero - tinoburitsa zvinoteedzeka, zvakaedzwa, zvakanyorwa kuita. Madhipatimendi edu maviri eR&D anoshanda mukusunga mikaha pakati pemareferensi echinyakare uye yazvino maitiro epamusoro. Kana mutengi akatumira mufananidzo unoratidza "ISO 7412", mainjiniya edu anoronga mativi ese, zvinhu, uye kupedzisa zvinodiwa kune anoshanda, anotemerwa zviyero - vobva vasimbisa kwavari.
Zvivakwa zvedu zvinogonesa iko kuomarara: mukati-mumba zinc yekuvhara mitsara neASTM B633 Kirasi Fe / Zn 5 corrosion yekuyedza, CNC machining nzvimbo ine chaiyo-nguva yekupisa kwemafuta muripo, uye yakazara batch traceability kubva mbishi bar stock lot nhamba kuenda kunze kwenyika chitupa.
Kuti uwane mapini chaiwo, tinopa:
Stainless simbi dowel pini pa ISO 2339 (metric) kana ANSI B18.8.2 (inch) Hardened alloy simbi mapini ane kuoma 45–50 HRC uye ≤0.008 mm runout Tsika GD&T mapakeji - anosanganisira chinzvimbo kushivirira kune datum A-B-C uye composite mbiri kudzora Zvinyorwa zvizere: Chitupa cheKuenderana, RoHS/REACH mishumo, uye chitupa chepakutanga Kutungamira nguva? 7 mazuva emasampuli. 15-20 mazuva ekugadzirwa kwemirairo - ine zero kukanganiswa pane dimensional kana metallurgical verification.
Mitemo iripo kudzivirira kukundikana - kwete kuzadza mapepa. Kuvhiringidza "ISO 7412" nezvinodiwa zveinjiniya zvinokanganisa kuchengeteka, kuvimbika, uye kuvimba. PaDewell, tinobata mubvunzo wega wega semubatanidzwa: jekesa chinangwa, simbisa fizikisi, wobva wavaka kune manhamba akakosha. Nekuti kana pini yekutsvaga inobata turbine blade jig kana kuenzanisa EV bhatiri module, hapana nzvimbo yemazita enzvimbo.
