ISO 4014 Hex Bolt
DIN 931 yog ib qho kev lees paub thoob ntiaj teb rau ib nrab threaded hex taub hau bolts. Nws qhov tseem ceeb ntawm qhov sib txawv ntawm cov threaded bolts nyob rau hauv kev faib ntawm nws shank mus rau hauv ib tug du, unthreaded seem thiab ib tug threaded zawm seem - ib tug tsim uas muab nws tshwj xeeb mechanical daim ntaub ntawv.
Khoom siv thiab lub zog
Manufacturing cov ntaub ntawv feem ntau poob rau hauv ob pawg:
Carbon Steel: Qib raws li kev ua tau zoo, nrog cov qib sib xws suav nrog 8.8 thiab 10.9. Cov lej no qhia txog lub zog tensile thiab qhov sib piv ntawm lub zog tawm los rau lub zog tensile kawg; cov nqi siab dua qhia tau tias muaj zog ntau dua thiab qhov hnyav dua -cov kabmob muaj peev xwm.
Stainless hlau: Feem ntau A2 (304 stainless hlau) thiab A4 (316 stainless hlau), qhov twg tus lej tom ntej (piv txwv li, "70") qhia lub zog tensile. Stainless hlau muab superior corrosion kuj.
Surface Treatment (Coatings)
Txhawm rau tiv thaiv ntau qhov chaw, carbon steel bolts tau txais ntau yam txheej:
Electrogalvanized
Feem ntau, tsawg- nqi, muaj nyob rau hauv nyiaj- dawb, xim tiav, thiab lwm yam.
Phosphating
Feem ntau siv rau tom qab oiling los yog kev koom ua ke nrog cov xim tshuab.
Dacromet
Muab kev tiv thaiv xeb zoo dua piv rau electrogalvanizing.
Kub-dip galvanizing
Nta cov txheej zinc thicker, haum rau cov ntug dej hiav txwv ib puag ncig, txawm hais tias qhov chaw tiav yuav tsis zoo li qub.
Cov ntawv thov tseem ceeb
Vim nws cov shank seem ua tau raws li nruj haum nrog mating qhov, DIN 931 yog tshwj xeeb tshaj yog haum rau cov qauv kev sib txuas uas yuav tsum tau shear quab yuam kuj thiab meej positioning. Thaum cov khoom muaj kev cuam tshuam rau sab nraud lossis kev vibration, lub shank du zoo tiv thaiv kev hnav -vim tshem tawm ntawm cov ntsia liaj qhov rooj thiab lub qhov phab ntsa. Yog li ntawd, nws yog feem ntau siv nyob rau hauv ** steel qauv siv, hnyav machinery, automotive chassis, thiab rail tsheb **- teb xav tau heev heev kev twb kev txuas kev nyab xeeb thiab precision.
