Description

Bottom dead center detector PS-464/462 is a detector to detect floating slugs and double stamping etc. in press stamping and output a stop signal to the press machine if such a malfunction is detected.
By each stroke, the detector samples the bottom dead center of the signal of the eddy current proximity sensor set up in the press die, and computes displacement of the bottom dead center from the sampled signal with the use of a microcomputer. The bottom dead center displacement is compared with the setting value. When the displacement exceeding the setting value is detected, a signal to stop the press is output.

Features


 Higher sensitivity
  • The accuracy of the sensor signal processing circuit has been improved. The maximum processing resolution has been developed to be 0.1 μm. Minute displacement at the bottom dead center can be detected.     
 Displacement check with digital display and micron-indicator
  • The displacement is displayed simultaneously both with the digital display having high reading accuracy and the micron-indicator easy to check the condition. This enables an easy-check of the operating conditions of the detector.     
 Displayed gap for sensor installation
  • The distance between the sensor head and a target is displayed at the time of installing the sensor. Without the use of the gap gauge, the sensor can be installed accurately.     
 Flexible adjustment of the sensor cable length
  • The cable compensation function enables fine adjustment of the cable length on site. The cable length can be freely set for each channel.     
 Developed detection timing
  • The external timing is produced from 2 inputs and the internal timing is from each channel. If the internal angle timing is used, the equivalent detection with the external timing can be achieved without an external cam.     
 Effective timing test
  • The timing test can detect out of control conditions such as unusual installation of the sensor and improper operation of the external cam.     
 Detection of sensor wire disconnection
  • A stop signal is output when PS-464/462 detects disconnection/defects of the sensor or disconnection of the sensor cable by the sensor disconnection function.
