Position Stability Analysis of Gripper Bars on Die-Cutting Machine

Abstract

Position stability analysis of gripper bars on die-cutting machine is one of the important factor which affects machining quality and production capacity. By introducing comprehensive influence parameter period ratio such as machine speed and mechanism natural frequency,mathematical model of gripper bars in stopping period has been established. The results indicate that dynamic motion error of gripper bars in stopping period show an increasing tendency so as to affect stable position with the increasing of period ratio. To ensure a stable position state in stopping period, finally two solutions are given out to satisfy high accuracy.
