Hydraulic Impact Dampers

Protect your PRESS and DIES by using Red Stag Hydraulic Impact Dampers

In the metal stamping industry, Hydraulic Impact Dampers are the solution to problems associated with breakthrough shock.  Hydraulic Impact Dampers will:

  • Protect the Dies
  • Protect the Press
  • Reduce Shock
  • Reduce Noise
  • Reduce Vibration

Engineered sets of Impact Dampers are fixed to the press bed and self activate at the precise moment of breakthrough.  The shock normally transferred to the press frame from the moving platen (bolster) is substantially reduced.  For hydraulic presses, shock that is transmitted throughout the complete hydraulic system (fittings, pipes, connections, valves and manifolds) is greatly reduced.  The typical die life is also prolonged and noise and vibration levels are reduced.

Red Stag Hydraulic Impact Dampers are of a very rugged design.  We have engineered them to withstand very high levels of shock, pressure change and impact stress.  Red Stag also designed this product to be very simple to set up and use.  The dampers are designed with an adjustment crown nut on top of the cylinder.  This nut assembly is used to set the point of contact with the downward movement of the press slide.  The nut is set so that the stroke of the damper starts at approximately the top surface of the material to be punched or blanked.  As the moving platen (bolster) approaches the work, the initial movement of the damper offers very little working resistance.

Red Stag Hydraulic Impact Dampers will not take up working tonnage of the press.  The design concept of the dampers is as follows:  When the press makes the material breakthrough, the damper will automatically react (approximately 1-2 mSec) with an artificial resistance to the press ram, thus reducing system shock.  With the return stroke, the dampers automatically reset for the next stroke.  The dampers are designed to be used in continuous operations.

The Damper system will restrict the flow and control the press movement.  No external hydraulic or electrical connections are required.  The system is totally self contained.
