Wedging structure for presses or the like

摘要

A wedge system disclosed for adjustably positioned tools in a forging press or the like. The system includes a wedge positioned between two assemblies and provided with a locking taper. Hydraulic means permit a lubricant to be supplied under pressure to the surfaces of the wedge so that the wedge is released and can float laterally even when large loads are applied to the system as for example during a tooling jam. The system totally encloses the wedge chamber preventing scale or other contaminants from rusting, pitting, or scarring the wedge surface. Hydraulic means are provided to lock the wedge in an adjusted position and power means are provided to move the wedge for adjustment.
