DIN933 304 A2-70 Hexagonal Bolt
Kufotokozera kwa Zamalonda
Malamulo a A-level ndi awa: d ≤ 24mm ndi l ≤ 10d kapena l ≤ 150mm (iliyonse yaying'ono); Malamulo a Gulu B ndi awa: d>24mm kapena l>10d kapena l>150mm (iliyonse yaying'ono). Pakati pawo, d akuyimira m'mimba mwake wa ulusi, ndipo l akuyimira kutalika kwa bolt. Magiredi osiyanasiyana azinthu ali ndi ma values ofanana a m'mphepete motsutsana s, diagonal e, makulidwe k, ndi kutalika kolekerera.
Mafotokozedwe a ulusi wa DIN 933 bolts ndi M3-M64, ndipo magiredi odziwika bwino a magwiridwe antchito a chitsulo cha kaboni ndi 8.8 ndi 10.9. Pamene d ≤ 39mm, chitsulo chosapanga dzimbiri nthawi zambiri chimakhala A2-50/A2-70/A4-70/A4-80, chomwe chingatanthauze ISO 3506-1 kapena DIN 267-11.
Mabowoti a muyezo uwu nthawi zambiri amakhala mu metric (ulusi wopyapyala) ndi ulusi wopyapyala, woyezedwa mu mamilimita (mm). Kulekerera kwa ulusi wopyapyala wa DIN 933 ndi 6g. Zophimba zomwe zimapezeka pamsika zimaphatikizapo zokutira zakuda, electroplating (zinc yoyera yabuluu, zinc yachikasu), ndi zokutira za zinc powder (GEO). Kuyenerera kwa kulekerera kusanachitike zokutira kumakhala 6g/6H, ndipo kuyenerera kwa gulu la kulekerera pambuyo pa galvanizing kumatha kusinthidwa kukhala 6h/6G. Komabe, chifukwa cha mphamvu ya makulidwe a pamwamba pambuyo pa zokutira, poyesa ulusi wokhala ndi magauji ofanana, pakhoza kukhala zochitika zomwe sizingagwirizane. Pakadali pano, kuyesa kuyika mtedza ndi zofunikira zofanana kungathe kuchitika.
Kugwiritsa ntchito
Bolodi ya DIN 933 ndi bolodi ya mutu yokhala ndi ulusi wokwanira yokhala ndi ntchito zosiyanasiyana, zomwe zimapezeka kwambiri m'magawo otsatirawa:
1. Kupanga makina: kugwiritsidwa ntchito popangira ndi kukonza zida zamakina, kulumikiza zigawo zosiyanasiyana zamakina.
2. Uinjiniya wa zomangamanga: monga kukonza nyumba zachitsulo, kukhazikitsa mabulaketi, zolumikizira, ndi zina zotero.
3. Makampani opanga magalimoto: angagwiritsidwe ntchito pomangirira zinthu monga injini, chassis, ndi thupi la magalimoto.
4. Zipangizo zamagetsi: Zimagwira ntchito yolumikiza ndi kukonza zipangizo zina zamagetsi.
5. Makampani opanga mafuta: oyenera kulumikiza zida zamakemikolo, mapaipi, ndi zina zotero. Mabotolo ena a DIN 933 amatha kukwaniritsa zofunikira zotsutsana ndi dzimbiri za chilengedwe cha mankhwala.
6. Makampani opanga zombo: amagwiritsidwa ntchito pomanga zombo ndi kukhazikitsa zida.
7. Ndege: Imagwiritsidwa ntchito m'malo omwe ali ndi zofunikira kwambiri kuti ikhale yamphamvu komanso yodalirika.
8. Mphamvu: kuphatikizapo kukhazikitsa ndi kukonza zida monga kupanga mphamvu ya mphepo ndi mphamvu ya dzuwa.
9. Kupanga mapampu ndi ma valve: monga zolumikizira za ma shaft a pampu ndi ma valvu.
10. Zipangizo zamafakitale: Kusonkhanitsa zida zosiyanasiyana zamafakitale.
