FIELD: mechanical engineering.
SUBSTANCE: invention refers to materials pressure-shaping and may be used in stamping presses. Diagnostic system contains strain analog-type sensors and hardware with signalisation system. Strain sensors are fixed in fours on each press column opposite to each other in parallel to longitudinal and transversal axes of the press and closed with circular detachable casings. Hardware includes industrial working station, crate system, cross-connection unit and uninterruptible power supply unit of double-conversion type. Industrial station represents computer system unit, liquid crystal display and functional keyboard arranged in single protected structure. Signalisation system is executed with preliminary and alarm levels of stresses in columns of press when it is loaded. Preliminary stress level exceeds allowed working stresses in press columns but is lower than alarm stress level which is set from condition of dangerous for press columns integrity overloading prevention.
EFFECT: diagnostic system reliability improvement and insuring of its rapidity is provided.
