Monitoring and control system for mechanical press

摘要

A system ( 100 ) for controlling the operation of a mechanical press ( 10 ) having a side link ( 60 ) for applying squeeze to a mold ( 80 ) includes a dial indicator ( 120 ) mounted to the side link. An actuator member ( 170 ) has a first end ( 172 ) connected to the side link ( 60 ) and an opposite second end ( 200 ) engaging the dial indicator ( 120 ). The actuator member ( 170 ) is configured to move relative to the side link ( 60 ) and actuate the dial indicator ( 200 ) in response to elongation of the side link. The dial indicator ( 200 ) indicates the magnitude of the squeeze applied by the side link ( 60 ). A strain transducer ( 150 ) is mounted to the side link ( 60 ). The strain transducer ( 150 ) includes a sensor ( 152 ) that is operative to provide a signal responsive to movement of the actuator member ( 170 ) relative to the side link ( 60 ).
