Combination Press Pads
The Combination Press Pad (T1F1) greatly reduces these forces through energy absorption. Due to a high coefficient of damping, it quickly dampens out this unrestricted oscillation and limits the number of shock pulses being transferred. This also ensures that the press frame and foundation will be completely at rest before the next blow is struck.
COMBINATION PRESS PADS
Also known as a T1F1 Press Pad sharply reduces forces through energy absorption. As a press blow is struck, the entire press frame including its foundation vibrates. This vibration is essentially free oscillation. Extremely high loads can be introduced into the internal press frame components and foundation area. The due to a high coefficient of damping, it quickly dampens out this free oscillation and limits the number of shock pulses being transmitted. This also ensures that the press frame and foundation will be completely at rest before the next blow is struck.
UNISORB Titan Shock Pads are inserted into the Red-Line material which acts as a frame for secondary support. Full contact is obtained with sizes matching each press foot. By varying the size and number of inserts, it ensures that the combination pads are working within optimum load ranges. This interdependent system allows the pads to be fine-tuned to the individual support requirements of the press.
PERFORMANCE AND OPTIMUM LOADS
The optimum load range for the Combination Press Pad Combination Pads with Titan Shock Pad inserts is between 800 and 1000 psi. This places the material in a favorable compressive work range for maximum pad life. Calculations are made to determine the approximate configuration for each pad set.
The performance of a press is greatly affected by how it is installed. Without proper support, a multitude of problems can occur from unwanted vibrations to premature wear of press components and tooling. Due to the higher cost of mounts, pad materials are often used where critical leveling and alignment is not required. Problems can occur however, when the combined weight/force of the press exceeds the capacity of these conventional materials. Careful selection is necessary to ensure that the pad accommodates the difference between the static and dynamic forces and other factors such as off-load conditions.
Most presses exhibit an interfering frequency in the 30 to 50 Hz range. This graph shows the attainable isolation values (30 and 40 Hz plotted) based on the deflection characteristics of the combination pads with the Titan inserts. Further isolation can be achieved by increasing the deflection with additional layers of the pads.
Unisorb® Red-Line Anchor Pads have been used to isolate presses for over 50 years, and provide excellent vibration control and damping. UNISORB Titan Shock Pads also provide excellent damping, especially under extreme loads and high shock applications. When used together, these well engineered pad materials reach a level of performance unattainable with standalone products. The Combination Press Pad offers static support, frictional contact and the capacity to handle impact forces with a wide safety margin.
