Hydraulic Shock Dampers

Increased Blanking Tonnage Capacity

Traditionally presses have de-rated tonnage capacity for blanking. Depending upon manufacturer this can be as much as two thirds of the forming capacity rating of the press.

In the real world the amount of de-rating to avoid overload equals the amount of reverse load encountered in each tooling application. As an example a 100 ton press running a job with 30 tons of reverse loading will have available only 70 tons of blanking capacity.

By adjusting the hydraulic shock damper control valves to capture 100% of the reverse load may generate a nominal 3-5% additional forward load tonnage, resulting in 95-97% of the forming tonnage available for blanking.

The result is the ability to run heavier jobs in smaller presses, requiring less capital investment.
