[Abstract]:The traditional roll forming control system can well control the operation of mechanical equipment, but there is room for improvement in man-machine interaction. In this paper, based on OpenSceneGraph, a cross-platform interactive graphic program, the control system of variable height roll die forming production line is developed. The 3D visual interface is added on the basis of the existing conventional control system interface. Real-time display of roll running state of variable cross section forming unit in production line. The research contents are described as follows: the mechanical structure of the production line of variable height roll die forming is analyzed and the mechanical system dynamics of the variable section forming unit of the production line is analyzed, and the working flow of each part of the production line is clarified. Determine the control platform scheme. According to the determined control platform scheme and the result of dynamic analysis, the hardware selection and the control platform are completed. Finally, the 3D visual interface of the variable section forming unit based on OSG is developed to improve the man-machine interaction experience of the roll forming control system and solve the problem. Siemens motion controller is used in this production line, and the model is SIMOTIOND 455-2. Through Abquas finite element simulation, the forming force of the variable section forming unit is obtained, and the output torque of each motor of the variable section forming unit is calculated. According to the torque, the required power is calculated. Then complete the motor selection according to the result. According to the determined control scheme, the necessary components, motors and hardware modules are selected, and IOs are assigned to design the software structure and control flow of the lower computer. After the software design of the upper computer is finished, Microsoft Visual Studio2010 is chosen as the IDEof the software, and the application interface is developed by using MFC. The 3D visual interface uses OSG interactive graphic program to display the position state of the variable cross section roll in real time. According to the standard format, the contents of the data packets are determined. Through the TCP/IP protocol, the upper computer sends control commands to the lower computer and receives the state information of the production line transmitted by the lower computer at the same time. After the above content is completed, the target workpiece is produced and the experimental verification is completed. This shows that the control system studied in this paper can control the production line better, and it is stable and reliable in the process of operation, and the production line basically realizes automatic machining. And it can display the moving state of the variable section forming part in real time.
