Roll forming is a continuous bending operation in which a long strip of sheet metal (typically coiled steel) is passed through sets of rolls mounted on consecutive stands, each set performing only an incremental part of the bend, until the desired cross-section profile is obtained. Roll forming is ideal for producing constant-profile parts with long lengths and in large quantities.
The roll forming process requires the precise setting of gap between two profiled rolls. In olden days the gap setting were done manually where the process consumes more time to precisely set the gap which intern increase the setup time and decreasing machine productivity. The new generation machines use Hydraulic Servo Actuators with inbuilt position feedbacks and Servo valves. The Servo actuators are controlled by motion controllers where the gap setting and control process is carried out just by click of a button.
The motion controller plays an important role in increasing the machine productivity. As productivity demands increase, more and more applications and processes require more sophisticated closed loop controllers. The new generation multi axes RMC150E motion controller from Delta Computer Systems was selected for this application. The RMC150E controller is a programmable motion controller where the machine operation sequences can be easily lined up.
