A Study on Exclusive Robot System for Hot Forging Operations

An exclusive robot system is being used to control hot forging operations with a hanger for handling materials during a high speed forging process. Controlling manipulators involve the rotational control in continuous rotation and incremental angle rotation modes. The position of a manipulator requires integrated control with a press to achieve the inch per press stroke for compensating an increase in workpiece length due to the cross section area reduction in the workpiece. Various sensors, such as pulse encoder, limit sensor, and etc., are interfaced to a P.L.C while the output is interfaced with some machine control devices, such as relays, solenoids, and servo valves. Limit switches and proximity switches are monitored in an interlock circuit.
