Siłownik montażowy Kraftpaket ze zintegrowanym tłumieniem ZED
Reliable process monitoring for pressing and smooth punching operations thanks to the integrated, adjustable damping function ZED
- Kraftpaket EK z tłumieniem ZED
The new integrated damping option allows an adjustable constant speed of the cylinder working rod during the approach stroke and power stroke, independent of the working forces. Now it is possible to almost fully compensate a stick-slip-effect at a press-in process, and when stamping compensate the sudden acceleration of the working rod when the opposing force is removed.
Press-in applications:
Depending on the application, chattering effects may occur during the press-in operation, the so-called stick-slip effect. This effect induces strongly fluctuating progressions of force/travel making a reliable process control difficult. And this chattering also generates undesirable press-in results and increased noises. With the new damping function ZED, this effect is almost completely compensated. The press-in operation happens controlled at constant speed. The force-travel curves can precisely be monitored and evaluated.
Punching applications:
The break through effect at the end of a punching operation causes an abrupt drop of the counterforce. This results in an instantaneous high acceleration of the cylinder working rod. The punching shock causes high noise levels and premature wear of the tools and the machine. With the new damping function ZED applied, the speed of the working rod remains nearly constant. Thereby shocks are prevented at the end position and noise levels are noticeably reduced.
Advantages:
+ Damping can electrically be initiated at any point of the stroke
+ damping is continuously adjustable
+ almost constant speed of working rod
+ gentle, monitored press-in of pieceparts is possible
Options:
+ speed control via proportional hydraulic valve
+ integrated travel measuring system, type ZWK
The TOX-Powerpackage type ZED can be ordered either with a manually adjustable flow control valve or with a solenoid operated proportional flow control valve. Either valve can be mounted in the same control block.
