纵剪剪刃受力分析及实践

Analysis and Practices of Force Working on Longitudinal Shear Knife

通过对纵剪剪刃进行受力分析,将纵剪剪刃倾角由4°20′改为4°50,′经过强度分析试验确定了纵剪安全系数,最终将钢板剪切最大厚度由原来的25 mm提高到30mm,提高了剪切能力。

By analyzing the force working on the longitudinal shear knife, the knife cutting angel is changed from 4°20′ to 4°50′, the safety coefficient of the longitudinal shear has been defined via strength analyzing and testing, thus the plate cutting thickness is increased from 25 mm to 30 mm at last, improving the shear cutting capacity.
