Design and Analysis of Automatic Bending Device for Steel Bar
A steel bar bending device was designed to meet the requirements of the current steel bar assembly construction and in-stallation process.Based on the steel bar bending process test,the device configuration with clamping and bending functions was pro-posed.Based on the structural characteristics of the bending device,the kinematic models of the clamping and bending mechanisms were established by theoretical analysis.Based on the application and design requirements of the bending mechanism,virtual prototype tech-nology was used to simulate and analyze the multi-body dynamics and finite element structure statics of the bending mechanism.The re-sults show that the bending mechanism moves smoothly in the process of movement,and the strength and stiffness of each member struc-ture are within a reasonable range,which meets the requirements of the move smoothness of the mechanism and the reliability of the me-chanical structure.The electrohydraulic position control system of the bending drive hydraulic cylinder was designed,and the feasibility of the control system was verified by simulation.Finally,the performance of the bending device was verified by test.The results show that the overall structural performance of the bending device meets the design and engineering requirements,which greatly improves the in-stallation efficiency of the steel bar,and the expected goal is achieved.
