Controller for the clutch/brake system on presses
 
 
Requirement:

Presses are some of the most dangerous drive machinery to operate. Therefore safety legislation stipulates special safety devices for these machine tools, for instance the use of two-hand controls. To safeguard against press malfunctions or mistakes by the operator (such as reaching into the press), press safety valves must have high flow rates and extremely fast pressure build-up and exhaust times. If any of the faults mentioned above occur, the pressure in the clutch system is released in the minimum possible time. This allows the braking system to intervene immediately and brake the descending ram, thereby preventing any accidental press movements.


Herion solution:

The clutch/brake system shall be controlled using press safety valves from the HERION Systemtechnik XSz double valve series/p>
Customer benefits:


  • Rapid pressure build-up and release

  • Dynamic self-monitoring facility

  • Meets the highest safety standards

  • Low maintenance

  • Long service life

 
 
 
 
Emergency Stop function for stopping machinery safely in the event of malfunction (e.g. on mechanical presses) and control of clutch/brake combinations
 
 
Requirement:

An "Emergency Stop" function is needed to prevent pressure still being applied to safety-relevant components in the event of a malfunction.
Smooth operation of the clutch and brake is also required in order to protect the mechanical components in the press.



Herion solution:

Safety valves from the XSz series combined with damping components for soft clutch and brake.



Customer benefits:

  • Damping component avoids jolts and protects the press drive

  • Low maintenance costs

  • Greater productivity

  • Lower costs

  • Long service life

  • Safety valves have dynamic self-monitoring facility (fail safe)
