Operating Parameters Calculation and Work Simulation of Three-Roller Universal Hydraulic Bending Machine
Abstract:The manufacturing process of three-roller universal hydraulic bending machine is introduced. Based on the processing which a machine manufacture maximum size plate, mechanical properties analysis is carried out in the mechanical system composed by upper roller and two lower rollers. The minimum radius of workpiece is calculated based on the main motor parameters. According to the previous results, down displacement of upper roller and Finite Element Analysis of processing is introduced. Previous calculation and simulation are verified by trial workpiece finally.
Keywords: Hydraulic bending machine;Operating Parameters Calculation Mechanical properties analysis Finite Element Analysis
