A feeder system for advancing a compressible material has a hydraulic circuit associated with a final compression stage. The hydraulic circuit includes a platen attached to a primary ram configured to travel within a primary cylinder. The platen is operatively connected to a main piston cylinder assembly and at least two ancillary piston cylinder assemblies. In a first mode of operation, the hydraulic circuit forces the ancillary piston cylinder assemblies to advance the platen and ram in a forward compression direction until they reach a first predetermined position between travel extremes, while the main piston cylinder assembly passively travels along in the forward compression direction. Once the first predetermined position is reached, in a second mode of operation, the hydraulic circuit additionally forces the main piston cylinder assembly to compress the compressible material. In a third mode of operation, the hydraulic circuit retracts the platen and primary ram.

A press system providing excellent energy efficiency for a whole press system and capable of achieving low prices is provided. A die cushion apparatus constituting a press system supports a cushion pad, includes a hydraulic cylinder which generates a die cushion load on the cushion pad when a slide of a press machine descends, the press machine includes a hydraulic cylinder which generates part of a press load on the slide when the slide descends.

A high-speed hydraulic forging press is disclosed. The high-speed hydraulic forging press includes a forging hammer, a movable beam, a main hydraulic cylinder, a single-rod elevation hydraulic cylinder, a plurality of main hydraulic pumps, a high-pressure energy accumulator, an intermediate-pressure energy accumulator, an oil tank, a programmable logic controller and a valve-regulation system. During a rolling process, when a rolling resistance applied to the forging hammer increases to cause pressure in the main hydraulic cylinder to reach a predetermined value, the programmable logic controller controls the valve-regulation system so that the high-pressure energy accumulator stops supplying the hydraulic oil to the main hydraulic cylinder, and that the hydraulic oil in the main hydraulic cylinder is supplied by at least one of the plurality of main hydraulic pumps. The high-speed hydraulic forging press exhibits remarkable advantages including a reasonable resource allocation, a simple structure, low equipment investment, and high energy utilization.
