DIN933 304 A2-70 Hexagonal Bolt
Tuairisgeul air na Toraidhean
Is iad na riaghailtean ìre-A: d ≤ 24mm agus l ≤ 10d no l ≤ 150mm (ge bith dè as lugha); Is iad na riaghailtean airson Clas B: d>24mm no l>10d no l>150mm (ge bith dè as lugha). Nam measg, tha d a’ riochdachadh trast-thomhas an t-snàthainn, agus tha l a’ riochdachadh fad a’ bholt. Tha luachan co-fhreagarrach aig diofar ìrean toraidh airson oirean mu choinneamh a chèile s, trast-thomhas e, tighead k, agus fulangas faid.
Is e M3-M64 an sònrachadh trast-thomhas snàth coitcheann airson boltaichean DIN 933, agus is e 8.8 agus 10.9 na ìrean coileanaidh stàilinn charboin cumanta sa mhòr-chuid. Nuair a tha d ≤ 39mm, mar as trice is e A2-50/A2-70/A4-70/A4-80 a th’ ann an stàilinn gun smal, agus faodaidh seo iomradh a thoirt air ISO 3506-1 no DIN 267-11.
Mar as trice, tha boltaichean na h-inbhe seo ann an snàthainn mheatrach (snàthainn garbh) agus snàthainn mhìn, air an tomhas ann am millimeatairean (mm). Is e 6g an fulangas airson snàthainn garbh DIN 933. Am measg nan còmhdach cumanta air a’ mhargaidh tha còmhdach dubh, electroplating (sinc gorm-geal, sinc buidhe), agus còmhdach pùdar sinc neo-electrolytic (GEO). Is e 6g/6H an fulangas a tha freagarrach ron chòmhdach sa mhòr-chuid, agus faodar an còmhlan fulangas a tha freagarrach às deidh galvanachadh atharrachadh gu 6h/6G. Ach, air sgàth buaidh tighead còmhdach uachdar às deidh còmhdach, nuair a thathar a’ dèanamh deuchainn air snàthainn le tomhasairean fulangas co-fhreagarrach, is dòcha gum bi suidheachaidhean ann far nach urrainn dhaibh a bhith iomchaidh. Aig an àm seo, faodar deuchainnean stàlaidh chnothan le sònrachaidhean a tha a’ maidseadh a dhèanamh.
Iarrtas
Tha bolt DIN 933 na bolt ceann sia-thaobhach làn-shnàthaichte le raon farsaing de thagraidhean, a lorgar gu cumanta anns na raointean a leanas:
1. Saothrachadh meacanaigeach: air a chleachdadh airson uidheamachd meacanaigeach a chruinneachadh agus a dhaingneachadh, a’ ceangal diofar phàirtean meacanaigeach.
2. Innleadaireachd togail: leithid structaran stàilinn a chàradh, camagan, luchd-ceangail, msaa. a stàladh.
3. Gnìomhachas nan càraichean: faodar a chleachdadh airson pàirtean leithid einnsean, chassis agus bodhaig chàraichean a cheangal.
4. Innealan dealanach: Bidh pàirt aca ann a bhith a’ ceangal agus a’ daingneachadh ann an cruinneachadh cuid de dh’ innealan dealanach.
5. Gnìomhachas peitriceimiceach: freagarrach airson ceangal uidheam ceimigeach, loidhnichean-phìoban, msaa. Faodaidh cuid de bholtaichean DIN 933 coinneachadh ri riatanasan an-aghaidh creimeadh na h-àrainneachd cheimigeach.
6. Gnìomhachas togail shoithichean: air a chleachdadh airson togail shoithichean agus stàladh uidheamachd.
7. Aerospace: Air a chleachdadh ann an sgìrean le riatanasan àrda airson neart agus earbsachd.
8. Raon lùtha: a’ gabhail a-steach stàladh agus daingneachadh uidheamachd leithid gineadh cumhachd gaoithe agus lùth na grèine.
9. Dèanamh pumpaichean is bhalbhaichean: mar luchd-ceangail airson shailean pumpaichean is gasan bhalbhaichean.
10. Uidheam gnìomhachais: Cruinneachadh diofar uidheam gnìomhachais coitcheann.
