ISO 7411 haisi chiyero chakataurwa zvakanyanya se ISO 898 kana ASTM A325-asi kana iwe uchitsanangura kana kutsvaga mapini ekutsvaga mapini eiyo chaiyo jigs, zvigadziriso, kana maturusi egungano, ndiro rimwe gwaro rinotsanangura kukwana, kushanda, uye kuchinjana. Takaona mainjiniya vachiisvetuka, vachifunga kuti "dowel pin" zvinoreva chinhu chimwe chete kune vatengesi, vozotarisana nemutengo unodhura apo mapini asingagari kana kuwana nguva dzose pamabhechi. Ndosaka isu takavaka gwara iri-kwete sekuoma kudzokororwa kwezvikamu, asi senzvimbo yakaedzwa-yakaedzwa yakavakirwa muchiitiko chaicho chekugadzira panzvimbo yedu yemaeka gumi muYongnian.
Izvo ISO 7411 Chaizvoizvo Inovhara (uye Izvo Zvisingaite)
TS EN ISO 7411: 2022 zviyero, kushivirira, zvinhu, uye pamusoro pekupedzisira zvinodiwa zvecylindrical nzvimbo yepini - inowanzonzi dowel pini - ine shanks isina kuverengerwa uye ingave yakatenderera, yakati sandara, kana ine misoro yakatsvuka. Inoshanda kumapini akagadzirwa kubva simbi, Stainless simbi, kana mamwe alloys, ane zita madhayamita kubva 1 mm kusvika 50 mm.
Sezvineiwo, ISO 7411 inoita kwete vhara mapini ane tapered, mapini echitubu, kana mapini ane grooved. Izvo zvakare hazvitsanangure zvivakwa zvemakanika senge kusimba kwesimba kana kuomarara-izvo zvinowira pasi pezviyero zvezvinhu (semuenzaniso, EN 10088-1 yemagiredhi asina tsvina kana ASTM A276). Pane kudaro, ISO 7411 inotarisisa mbiru nhatu dzinoshanda: kurongeka kwedimensional, geometric control (kutwasanuka, cylindricity), uye kuvimbika kwepasi (kukasharara ≤ Ra 0.8 μm).
Isu tinoyedza batch yega yega ISO 7411-inoenderana pini tichishandisa calibrated CMMs uye optical comparator. Mune imwe ongororo ichangoburwa, mutengesi akati kuteererwa asi akaendesa mapini ane 0.025 mm runout-kunze kwe ± 0.005 mm kushivirira kweØ12 mm pini. Kugadzirisa? Kusimbisa kudzora kupisa kwekudzivirira uye kuwedzera post-kugaya kutwasuka kwechokwadi. Ndiwo musiyano pakati pekutevedzera mapepa uye kuvimbika kwekushanda.
Kushivirira Kwakakosha Iwe Haugone Kufuratira Mukuita
ISO 7411 inopa makirasi ekushivirira zvichienderana nekukosha kwekushandisa. Vazhinji vashandisi veindasitiri vanongomira kukirasi m6 ye shank dhayamita-yakasimba inokwana yekutsikirira-inokwana maapplication uko kudzokororwa kwenzvimbo kunonyanya kukosha kupfuura nyore kuisa.
Shank diameter: m6 tolerance is -0.006 mm kusvika −0.020 mm yepini ye10 mm-zvichireva kuti saizi chaiyo inofanira kudonha pakati pe9.980 mm ne9.994 mm Musoro dhayamita: + 0.000 mm / + 0.021 mm (yakagara yakawandisa kune shank) Kureba kushivirira: ± 0.2 mm yemapini anosvika 50 mm kureba; ± 0.3 mm kupfuura izvozvo Runout: Max 0.005 mm pamusoro pehurefu hwakazara-yakayerwa pasi pemutoro unodzorwa, kwete mahara Hezvino izvo zvinokwidza vanhu kumusoro: ISO 7411 inobvumira kureba kwemusoro kusimuka kusvika ± 0.2 mm, asi akawanda magadzirirwo ekugadzirisa anovimba nekubata musoro kune axial kumira. Kana jig yako ichishandisa musoro sedatum pamusoro-uye vazhinji vanoita-iwe uchada kusimba kutonga. Isu tinopa tsika musoro-kureba kushivirira pasi kusvika ± 0.05 mm, yakasimbiswa paASME Y14.5.
Zvishandiso & Pedzisa Sarudzo Idzo Dzinobata Chaiyo-Nyika Kuita
Simbi isina tsvina (AISI 304, 316) inotonga ISO 7411 maodha enzvimbo dzinoita ngura - funga mitsara yekugadzira chikafu kana kusangana kwemidziyo yemugungwa. Asi kuoma kunokosha kupfuura sarudzo yealloy mune yakakwirira-kutenderera kunyorera. Isu tinogara tichipa mazana matatu nemana mapini akaomeswa kusvika pa35–40 HRC kuburikidza nekuoma kwemvura, kwete kungovharirwa stock. Sei? Husina kuomeswa 304 dents mushure ~ 500 kuiswa mualuminium jigs. Shanduro dzakaomeswa dzinopfuura 5,000 kutenderera pasina deformation.
Kupera kwepamusoro hakusi kwekuzora. Ra> 0.8 μm inowedzera kukwesha panguva yekutsikirira-yakakodzera uye inomhanyisa galling mumagungano asina tsvina-pa-stainless. Yedu in-house electropolishing line inoderedza Ra kusvika 0.2-0.4 μm apo ichibvisa micro-burrs inokonzera nhema kupindirana. Vatengi vanoshuma 30% nekukurumidza kugadzirisa kugadzirisa nguva mushure mekuchinja.
Hot-dip galvanized pini? Haina kuvharwa-uye haina kukurudzirwa. Zinc buildup inokanganisa madhayamita akakosha uye inokanganisa kupindira chaiko. Zvekushandisa zvekunze, tinoshandisa duplex isina tsvina (1.4462) ine passivation pachinzvimbo.
Compliance Verification: Kunze kweSitifiketi
Chitupa cheKuenderana chinoti "ISO 7411 inoenderana" inoreva zvishoma pasina data rinoteedzera. KuDewell, yega yega ISO 7411 ngarava ine:
Dimensional yekuongorora rondedzero inoratidza zviyero chaizvo zvinopesana nezvose zvakakosha maficha (shank Ø, musoro Ø, kureba, kumhanya) Material test report inosimbisa giredhi, chemistry, uye kuoma Surface roughness verification pane ISO 4287 Batch-chaiwo kupisa kupisa marekodhi (kana zvichibvira) Isu hatiite batch-bvunzo-isu 100% -kuongorora mapini anosvika Ø16 mm. Kune madhayamita akakura, isu tinoshandisa statistically inoshanda sampling pa ISO 2859-1, yakasimbiswa kune Level II kuomarara. Ndiwo machengetero atinoita zero isiri-conformance mishumo pane ISO 7411 kutumira kubva Q3 2022.
Mumwe mutengi kuGermany aida ISO 7411 mapini emotokari muviri-in-white tooling. Mutengesi wavo wekutanga akatadza kuongororwa katatu nekuda kwekusawirirana kwemusoro. Isu takagadziridza gadziriso yekukuya, takawedzera mu-process laser micrometry, uye takaunza yekutanga-pass mvumo pane yechina kuendesa.
Nei Uyu Mwero Uchikosha Kupfuura Zvazvaimboita
Sezvo kugadzira kuchinjika kune modular tooling, dijitari mapatya kusimbiswa, uye zero-chirema kuungana, kutsvaga pini kuenderana kunomira kuve ruzivo - inova inodiwa system. Kutsauka kwe 0.01 mm mudhayamita yepini kunogona kushandura kurongeka ne 0.03 mm kuyambuka 1,200 mm weldment. Izvo zvakakwana kurasa chassis yese subassembly.
ISO 7411 inopa mainjiniya mutauro wakafanana-uyo unotsigirwa neinoyerika, inodzokororwa maitiro. Hazvisi zvemapepa. Ndezvekubvisa kusiyanisa panguva iyo zvikamu zvinosangana.
Kana iwe uri kutsanangura kana kutsvaga ISO 7411 pini, tanga pano: tsanangura yako yekushanda kushivirira stack-up kutanga, wozosarudza zvinhu uye pedzisa kune yako nharaunda-kwete imwe nzira yakatenderedza. Uye kana iwe uchida kurongeka, akaedzwa, akakodzera-kune-chinangwa mapini, Dewell Fasteners inovaburitsa izere nedimensional pachena, pasina kunze.
