Press shutheight adjustment using bolster hydraulic tie rod assemblies

A shutheight adjustment system incorporating tie rods and accompanying hydraulic tie rod nut assemblies in connecting a bed to a bolster of a mechanical press for dynamically altering the tensioning of the tie rods. 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 bolster may be increased, thereby increasing the press shutheight.
