Abstract: A hydraulically-operated press-driven tool actuation system includes a press-driven hydraulic power device and/or a hydraulically-powered tool actuator. In the tool actuator, at least two pistons are carried by a housing, and at least one return device is carried by the housing laterally inboard of the pistons. In the power device, a pump includes a piston disposed in a pump cylinder for pressurizing hydraulic fluid therein. An accumulator is in fluid communication with the pump cylinder, and includes a piston disposed in an accumulator cylinder that houses hydraulic fluid on one side of the piston. A body supports the pump and accumulator thereon and is in fluid communication between the pump and accumulator cylinders. The body includes a pressure relief valve downstream of the pump cylinder and upstream of the accumulator cylinder, and a check valve downstream of the accumulator cylinder and upstream of the pump cylinder.

Abstract: A delay return gas spring including a piston at least partially received in a cylinder for reciprocation between extended and compressed positions over a cycle including a compression stroke and a return stroke. A seal disposed between the cylinder and the piston separates a primary chamber on one side of the seal from a secondary chamber on another side of the seal during a portion of the cycle. A passage communicates with the secondary chamber and with the primary chamber. The seal is relatively movable between an open position permitting free flow of gas through the passage to a closed position at least partially restricting gas flow through the passage so as to permit gas in the secondary chamber to be compressed in response to movement of the piston toward its extended position, thereby reducing a net return force on the piston and decreasing a velocity of the piston.

Abstract: A gas spring for forming equipment, including a piston received at least partially in a cylinder for reciprocation between extended and retracted positions, and including a throttling passage disposed between the piston and the cylinder in fluid communication between first and second pressure chambers during at least a portion of the reciprocation of the piston. The throttling passage is of variable cross-sectional area, which varies with a length of the passage to at least partially restrict gas flow therethrough in a manner varying with return of the piston toward its extended position to decelerate the piston at a predetermined rate.
