Abstract
A shutheight adjustment system incorporating hydraulic tie rod nut assemblies for dynamically altering the tensioning and compression of the tie rods of a power press. Each hydraulic tie rod nut assembly includes a cylinder with an inner sliding piston threadably engaging the tie rod. A pressurizing mechanism injects pressurized fluid within a chamber formed by the piston and cylinder. By increasing pressure within the chamber of the hydraulic tie rod nut assembly, compression between the press bed and press crown may be increased thereby reducing the press shutheight.
