Monitoring punching tools during punching process - by detecting parameters, e.g. body signal noise and punching force, in time correlation with punching process

摘要

One or more significant signal parameters are detected via sensors mounted on the punching tool in time correlation with the punching process and are compared with predefined demand values. The body noise amplitude of the tool is monitored for compliance with a tolerance range. The permissible fluctuation of the body noise signal is not limited during defined time intervals so that punch specific impulses remain unchanged. The amplitude of the punching force on the tool can also be detected using a fixed range of fluctuation. The maximum and/or the integral of the punching force is/are determined over the punching period and compared with predefined demand values. USE/ADVANTAGE - For monitoring punching tools during punching process. Punching tool may be monitored throughout entire production process.
