【摘要】 在自动辊锻过程中,机械手在杆系机构的作用下,夹带工件做往复运动。机构简图绘制的速度曲线表明,机械联动结构的机械手速度呈正弦曲线特征。采用DEFORM-3D进行锻件运动速度场模拟,锻件速度波动很小,锻件和机械手的运动存在明显的异步性,需要对速度差进行补偿。结合试验结果,分析研究了补偿方向和补偿时间对辊锻成形的影响。更多还原

【Abstract】 The movement of manipulator and blank was driven by link mechanism in automatic roll forging.The velocity curve of manipulator based on diagram of mechanism indicates that the velocity curve of the manipulator is in the form of sinusoid.Simulation by DEFOEM-3D shows that the sinuosity of the velocity of blank is rather small,so there is asynchrony between the movement of the blank and manipulator,and the velocity difference is necessary to be compensated.The effect of the direction and time of compensation on roll forging were analyzed based on experimental results.更多还原
