Research on Control System of Roll Forming Production Line with Fixed Mould and Moving Roll of Variable Cross-Section

The roll forming production line with fixed mould and moving roll of variable cross-section is a hydromechatronics line that implements the automatic processing of vehicle parts. Some technical problems of mass production of complicated cross section parts can be solved successfully by the production line, such as the low stability, the uncontrolled dimensional accuracy and the sheet deformation while a variable cross-section is cut off. The control system for the complete production line mainly consists of these parts: Siemens Simotion D455-2 motion control system, IPC, touch screen, ET200M input and output modules and so on. In order to develop the control system for the production line, the article completed system general design, full-closed loop control structure design and software design. It also completed building of hardware platform, development of software system and research of interpolation algorithm. Through several experimental verifications, the control system for the production line can meet the requirement of actual production.
