Monitoring device for press machine clutch brake

The utility model relates to a monitoring device which is used for real-time monitoring working state of the press machine clutch brake. A press machine clutch brake is arranged on a press machine and enables a flywheel of the press machine to joint with or detach from a main transmission shaft of the press machine, thereby realizing transmitting a torque to the main transmission shaft or stopping transmitting the torque to the main transmission shaft; and the monitoring device comprises a first sensor, a second sensor, a control module, a controller and an annunciator. The monitoring device can monitor the working state of the press machine clutch brake in real-time, and can raise an alarm to remind an operator to change or maintain the press machine clutch brake when the clutch brake anomaly works.
