Nkhani Za Kampani
Opanga aku China amathandizira mabizinesi kugwiritsa ntchito ukadaulo wazidziwitso pachitukuko, kumvetsetsa zambiri zamakampani, ndikukupatsirani ntchito zosavuta komanso zachangu: mkati mwa hexagonal cylindrical.
Pali gulu la ma bolts a hexagonal potengera kuuma, kulimba kwamphamvu, mphamvu zokolola, ndi zina zambiri za waya wa wononga, womwe ndi mulingo wa mabawuti a hexagonal. Pazida zopangira zosiyanasiyana, magawo osiyanasiyana a ma bawuti amkati a hexagonal amafunikira kuti agwirizane nawo. Maboti amkati a hexagonal onse ali ndi magiredi otsatirawa: ma bawuti amkati mwa hexagonal amagawidwa kukhala wamba komanso amphamvu kwambiri malinga ndi mphamvu zawo. Mabowuti wamba a hexagonal amatanthawuza giredi 4.8, pomwe ma bolt amphamvu kwambiri amatanthawuza giredi 8.8 kapena kupitilira apo, kuphatikiza giredi 10.9 ndi giredi 12.9. Maboliti a Grade 12.9 hexagon socket bolts nthawi zambiri amatanthawuza zomangira zakuda za hexagon socket mutu wokhala ndi mawonekedwe okulungidwa, mtundu wachilengedwe
1. Mphamvu yokhazikika ya bawuti imafika pamlingo wa 400MPa;
2. Chiŵerengero cha mphamvu zokolola za bawuti ndi 0,6; Mphamvu yotulutsa mwadzina ya bawuti ndi 400 × 0.6 = 240MPa.
Maboti amphamvu kwambiri okhala ndi magwiridwe antchito a 10.9, opangidwa ndi zinthu zomwe zathandizidwa ndi kutentha, amatha kukwaniritsa:
1. Mphamvu yokhazikika ya bawuti imafika pamlingo wa 1000MPa;
2. Chiŵerengero cha mphamvu zokolola za bawuti ndi 0,9; Mphamvu yotulutsa mwadzina ya bawuti imafika pamlingo wa 1000 × 0.9 = 900MPa.
Tanthauzo la kachitidwe ka ma bawuti amkati mwa hexagonal ndi muyezo wodziwika padziko lonse lapansi. Maboti okhala ndi giredi yofananira, mosasamala kanthu za kusiyana kwawo kwakuthupi ndi koyambira, amakhala ndi magwiridwe antchito ofanana, ndipo giredi lantchito lokha ndiloyenera kusankhidwa kuti lipangidwe.
Magulu a ma bolts a hexagonal ali ngati chonchi, ndipo mtengo wamsika ukhala wosiyana malinga ndi kalasi. Nthawi zambiri, mabawuti amphamvu kwambiri a hexagonal ndiokwera mtengo kwambiri kuposa ma bolt wamba a hexagonal. Magiredi anayi omwe amagwiritsidwa ntchito kwambiri pamsika ndi 4.8, 8.8, 10.9, ndi 12.9.
Mutu wa bawuti wa hexagonal uli pakati komanso wokhotakhota, zomwe zingayambitse mavuto akulu. Mwachitsanzo, kuchokera ku maonekedwe a mankhwala, sizowoneka bwino. Nkhani ina ndi yokondera, yomwe ingapangitse kuti singano ya chida chopangira ithyoke mosavuta. Vuto lalikulu kwambiri lingayambitsenso zinthu zingapo monga kusweka kwa ma bolts a hexagonal.
