通过对滚切式定尺剪机构的原理分析,建立以曲轴转角为变量的上刀架任意点轨迹求解方程,在此基础上对剪切机构参数进行优化,使剪刃重叠量更加均匀。 Based on the principle analysis of the rolling-shear length-shear mechanism, the equation of any point on the upper tool rest with the crank angle as the variable is established. Based on this, the parameters of the shear mechanism are optimized to make the overlap amount of the cutting edge more uniform.
