|
On-line monitoring of forging press could raise labor productivity,the economic benefits of enterprise and the utilization rate of equipment efficiently during production process.Based on this,the on-line monitoring instrument for the forging press of 4 stages during production process was developed.The pressure signal was detected with the piezoelectricity type pressure sensor.The pulse signal was produced by close switch.The analog signal circuit with charge amplifier,strain wave,automatic zero and absolute value circuits was adopted to change the physical quantities into electronic signals.A/D converting and data processing were executed to display and monitor production process for the forging press by the intelligent monitoring instrument with 8098 monolithic computer as foundation.Application result shows that the instrument is quick to respond speed,has high detection precision,and is steady and reliable,which are satisfied with the requirement of on-line monitoring.
