    摘要： A press for applying force to a workpiece, having a piston-andcylinder arrangement connected to a wedge which actuates the ram. The piston-and cylinder arrangement includes two pistons selectively displacable for either pressing, or for impacting the workpiece. Weights are arranged on a spindle threadingly received in the wedge for driving the wedge, on the flywheel principle.

    摘要： Designs of a tool for seating engine pistons and related methods are disclosed. For example, a tool may comprise a mount element, coupled to a support element, with at least one sleeve shaped to slide onto one or more studs on an EMD engine block. The tool may also comprise a locator element, coupled to the mount element, having a guiding ring positioned relative to the at least one sleeve. The tool may further comprise a cantilever beam pivotally coupled to the support element. The tool may additionally comprise a push rod inserted through the guiding ring and coupled to the cantilever beam, such that a pivoting motion of the cantilever beam causes a linear movement of the push rod through the guiding ring. An attachment element, located on one end of the push rod, may be adapted to attach to a piston of the EMD engine.

    摘要： A system is provided for two speed movement of a hydraulically driven element. The system includes a housing for a primary piston having a longitudinal bore open at one end. A secondary piston is received within the open bore end to define a secondary expandable reservoir within the primary piston. The primary piston includes a secondary working face disposed within the secondary expandable reservoir and a primary working face disposed in a primary expandable reservoir. High pressure hydraulic fluid is introduced into the secondary expandable reservoir for high speed movement. When the primary piston reaches a predetermined location, high pressure hydraulic fluid is introduced into both reservoirs for low speed movement.

    摘要： A forming machine having at least two piston means for providing a deforming force between the anvil block and ram. The piston means includes a first piston surface area that is substantially different than a second piston surface area. The smaller piston surface area is fixedly attached to the ram to effect hammering of the deformable material. The first and second piston surface areas are moved with the same hydraulic driving medium. The first and second piston surface areas are movable and controllable independently of each other.
