Roll Forming Machine With Variable Cross-section Transmission Of Three-dimensional Modeling And Dynamic Simulation

This article introduces the Roll forming technical features and applications, both at home and abroad steel roller bending the development of planar kinematic analysis, Roll forming process of an analysis, analysis of the principle of rotation speed; based on two-dimensional structural analysis, the use of Pro / E software for the variable cross-section roller bending molding machine Virtual Prototyping Modeling in Pro /E in the molding machine kinematics and dynamics simulation carried out by the variable cross-section roller curved shape of the simulation exercise control law products, and the shape of sample size for analysis of the causes of error compensation.In this paper, the results and conclusions are as follows:1,initially on the biaxial bending roller with variable cross-section of the molding machine structure, performance, working principle;2,Analysis of variable cross-section of the molding machine plate bending roller drive structure of the two programs and the use of mechanical principle of the movement, rotation speed of analysis, come up with the best drive of the backplane design, the design of the ball screw drive;3,Variable cross-section of the molding machine roller roller bending plate contact point with the speed of analysis, come out of the ideal conditions for the track plate;4,Sample of typical simulation of kinematics, dynamics analysis of simulation results, to draw the smallest error compensation;Roll forming of our research is also based on the initial stage, this paper presents the use of virtual prototyping technology to the roller plate bending machine for kinematics, dynamics simulation analysis for the project on the application of variable cross-section cold-formed molding technology and equipment designed to provide a technical reference.
