Tuam Tshoj cov tuam txhab tso cai rau cov tuam txhab siv cov ntaub ntawv thev naus laus zis rau kev txhim kho, nkag siab txog kev lag luam cov ntaub ntawv, thiab muab kev pabcuam yooj yim thiab ceev rau koj: sab hauv hexagonal cylindric
2024-09-10 IB
Muaj kev faib tawm ntawm hexagonal bolts raws li qhov hardness, tensile zog, yield zog, thiab lwm yam ntawm cov ntsia hlau hlau, uas yog qib ntawm hexagonal bolts. Ntawm cov khoom sib txawv, cov qib sib txawv ntawm sab hauv hexagonal bolts yuav tsum tau ua raws li lawv. Sab hauv hexagonal bolts tag nrho muaj cov qib hauv qab no: sab hauv hexagonal bolts tau muab faib ua qhov zoo tib yam thiab siab zog raws li lawv lub zog. Ordinary hexagonal bolts xa mus rau qib 4.8, thaum lub zog siab hexagonal bolts xa mus rau qib 8.8 lossis siab dua, suav nrog qib 10.9 thiab qib 12.9. Qib 12.9 hexagon socket bolts feem ntau xa mus rau dub hexagon socket taub hau screws nrog cov qauv dov, xim ntuj
kev ua tau zoo
1. Lub nominal tensile lub zog ntawm cov khoom siv ntsia liaj qhov rooj ncav cuag 400MPa qib;
2. Lub zog sib piv ntawm cov khoom siv ntsia liaj qhov rooj yog 0.6; Lub nominal yield zog ntawm cov khoom siv ntsia liaj qhov rooj yog 400 × 0.6 = 240MPa.
Lub zog muaj zog bolts nrog qib kev ua tau zoo ntawm 10.9, ua los ntawm cov ntaub ntawv uas tau kho cua sov, tuaj yeem ua tiav:
1. Lub nominal tensile lub zog ntawm cov khoom siv ntsia liaj qhov rooj ncav cuag 1000MPa qib;
2. Lub zog ntawm qhov sib piv ntawm cov khoom siv ntsia liaj qhov rooj yog 0.9; Lub nominal yield zog ntawm cov khoom siv ntsia liaj qhov rooj mus txog qib 1000 × 0.9 = 900MPa.
Lub ntsiab lus ntawm qib kev ua tau zoo ntawm sab hauv hexagonal bolts yog ib qho kev lees paub thoob ntiaj teb. Bolts nrog tib qib kev ua tau zoo, tsis hais lawv cov khoom siv thiab keeb kwm sib txawv, muaj qhov ua tau zoo ib yam, thiab tsuas yog qib kev ua tau zoo yuav tsum raug xaiv rau kev tsim.
Kev faib tawm ntawm hexagonal bolts yog qhov zoo li qhov no, thiab tus nqi hauv khw yuav txawv nyob ntawm qib. Feem ntau, lub zog siab hexagonal bolts yog twv yuav raug nqi ntau dua li qub hexagonal bolts. Plaub qib feem ntau siv hauv khw yog 4.8, 8.8, 10.9, thiab 12.9.
Lub taub hau ntawm hexagonal ntsia liaj qhov rooj yog tawm hauv nruab nrab thiab nkhaus, uas yuav ua rau muaj teeb meem loj. Piv txwv li, los ntawm cov tsos ntawm cov khoom, nws tsis yog aesthetically pleasing zuag qhia tag nrho. Lwm qhov teeb meem yog tias nws tsis ncaj ncees lawm, uas tuaj yeem yooj yim ua rau cov cuab yeej tsim khoom tawg. Qhov teeb meem loj tshaj plaws kuj tuaj yeem ua rau muaj ntau yam teeb meem xws li kev tawg ntawm hexagonal bolts.
