ABSTRACT:
A hydraulic press construction uses multiple alternating plates for the press frame sides and ends, and has joints which provide exceptional strength, high safety factors and a rigid frame for high tonnage applications. The joints function to utilize the full shear load capacity of the multiple adjoining faces of the plates in the joint sections. Multiple tensioned shear rods and/or high strength adhesive join the plates together at joint locations, and keys or tongue and groove configurations may be employed in the joints. These elements provide press joints that are rigid and that have high strength. They give the press frame a high resistance to deflection and distortion under load, as well as the capability for precision operations at press loads up to thousands of tons. A special hydraulic cylinder for the press also is described.
