Txhua series ntawm cov ntsia hlau customization

Qhov ntsuas qhov ntsuas qhov ntsuas tau tsim los ntawm ob ntu ntawm cov lej, uas feem ntau sawv cev rau lub zog tensile lub zog ntawm cov ntsia liaj qhov rooj thiab cov txiaj ntsig piv ntawm cov khoom. Piv txwv li, lub ntsiab lus ntawm cov ntsia hlau nrog qib ua tau zoo ntawm 4.6 yog: tus lej hauv thawj ntu (4 hauv 4.6) yog 1/100 ntawm lub zog tensile lub zog (n / mm2) ntawm cov khoom siv, uas yog, Fu ≥ 400N / hli 2; Tus lej hauv ntu thib ob (6 hauv 4.6) yog 10 npaug ntawm cov txiaj ntsig piv ntawm cov khoom siv ntsia liaj qhov rooj, uas yog, FY / Fu = 0.6; Cov khoom ntawm ob tus lej (4) × 6 = "24") yog 1 /10 ntawm qhov taw qhia tawm los (lossis lub zog tawm los) (n / mm2) ntawm cov khoom siv, uas yog, FY ≥ 240n / mm2.

Raws li kev tsim khoom raug, cov ntsia hlau zoo ib yam ntawm cov qauv hlau tuaj yeem faib ua peb qib: A, B thiab CA Qib B tau kho kom zoo dua, uas feem ntau siv rau cov khoom siv kho tshuab, thiab qib C yog ntxhib ntsia hlau. Tshwj tsis yog qhov tshwj xeeb tau teev tseg, cov ntsia hlau zoo ib yam ntawm cov qauv hlau feem ntau zoo sib xws qib C bolts nrog qib kev ua tau zoo ntawm 4.6 lossis 4.8.
