Design and Simulation of a New Type of Device for Steel Bar Bending

In order to realize the process of bending after placing the reinforcement into the mesh, a new kind of reinforcement bending mechanism was designed. After simplifying the mechanism, the mathematical model was established, and the kinematics and dynamics of the mechanism were analyzed and simulated with ADAMS to verify the rationality of the mechanism and provide initial data for the next finite element analysis. ANSYS was used to analyze the dangerous motion state of the mechanism to verify the reliability of the mechanism. Finally, the physical prototype was manufactured and bending test was performed. The mechanism can not only meet the requirements of this special process, but also be used as the actuator of six axis robot to make the process of steel bar bending more intelligent.
