DIN933 304 A2-70 Bolt hecsagonol
Disgrifiad Cynhyrchion
Y rheoliadau lefel A yw: d ≤ 24mm ac l ≤ 10d neu l ≤ 150mm (pa un bynnag sydd leiaf); Y rheoliadau ar gyfer Dosbarth B yw: d>24mm neu l>10d neu l>150mm (pa un bynnag sydd leiaf). Yn eu plith, mae d yn cynrychioli diamedr yr edau, ac mae l yn cynrychioli hyd y bollt. Mae gan wahanol raddau cynnyrch werthoedd cyfatebol ar gyfer ymylon gyferbyniol s, croeslin e, trwch k, a goddefgarwch hyd.
Manyleb diamedr edau cyffredinol bolltau DIN 933 yw M3-M64, a'r graddau perfformiad dur carbon cyffredin yw 8.8 a 10.9 yn bennaf. Pan fydd d ≤ 39mm, dur di-staen fel arfer yw A2-50/A2-70/A4-70/A4-80, a all gyfeirio at ISO 3506-1 neu DIN 267-11.
Mae bolltau'r safon hon fel arfer mewn metrig (edau bras) ac edau mân, wedi'u mesur mewn milimetrau (mm). Y goddefgarwch ar gyfer edau bras DIN 933 yw 6g. Mae haenau cyffredin ar y farchnad yn cynnwys haen ddu, electroplatio (sinc gwyn glas, sinc lliw melyn), a haen powdr sinc an-electrolytig (GEO). Y goddefgarwch ffit cyn cotio yw 6g/6H yn bennaf, a gellir newid y band goddefgarwch ar ôl galfaneiddio i 6h/6G. Fodd bynnag, oherwydd dylanwad trwch yr haen arwyneb ar ôl cotio, wrth brofi edafedd gyda mesuryddion goddefgarwch cyfatebol, efallai y bydd sefyllfaoedd lle na allant ffitio. Ar yr adeg hon, gellir cynnal profion gosod cnau gyda manylebau cyfatebol.
Cais
Mae bollt DIN 933 yn follt pen hecsagonol wedi'i edau'n llawn gydag ystod eang o gymwysiadau, a geir yn gyffredin yn y meysydd canlynol:
1. Gweithgynhyrchu mecanyddol: a ddefnyddir ar gyfer cydosod a gosod offer mecanyddol, gan gysylltu gwahanol gydrannau mecanyddol.
2. Peirianneg adeiladu: megis trwsio strwythurau dur, gosod cromfachau, cysylltwyr, ac ati.
3. Diwydiant modurol: gellir ei ddefnyddio ar gyfer clymu rhannau fel yr injan, y siasi a chorff ceir.
4. Dyfeisiau electronig: Maent yn chwarae rhan wrth gysylltu a thrwsio wrth gydosod rhai dyfeisiau electronig.
5. Diwydiant petrocemegol: addas ar gyfer cysylltu offer cemegol, piblinellau, ac ati. Gall rhai bolltau DIN 933 fodloni gofynion gwrth-cyrydu'r amgylchedd cemegol.
6. Diwydiant adeiladu llongau: a ddefnyddir ar gyfer adeiladu llongau a gosod offer.
7. Awyrofod: Defnyddir mewn ardaloedd â gofynion uchel ar gyfer cryfder a dibynadwyedd.
8. Maes ynni: gan gynnwys gosod a thrwsio offer megis cynhyrchu pŵer gwynt ac ynni solar.
9. Gweithgynhyrchu pympiau a falfiau: fel cysylltwyr ar gyfer siafftiau pympiau a choesynnau falf.
10. Offer diwydiannol: Cydosod amrywiol offer diwydiannol cyffredinol.
