A waste compaction apparatus may include a housing and a connector arm. The housing may define a drive chamber and a compaction chamber and the connector arm may include a drive piston portion movably positioned within the drive chamber and a compaction piston portion movably positioned within the compaction chamber. The drive chamber may be selectively fluidly coupleable to the near-vacuum of outer space, such that the compaction piston portion of the connector arm is configured to move within the compaction chamber to compact waste material contained within the compaction chamber in response to movement of the drive piston portion of the connector arm within the drive chamber.

A drive apparatus includes a movable member, at least one linear electrical actuator for generating a first force, and at least one linear hydraulic actuator for generating a second force. The at least one linear electrical actuator and the at least one linear hydraulic actuator are arranged such that the first force and the second force act in parallel on the movable member in order to result in a combined force.

A modular press suitable for use in the manufacture of EWC products may include a plurality of frame modules coupled together and aligned along a feed path axis. Each frame module may have a generally planar body supported on a corresponding pair of bases, an elongate aperture, an upper and a lower platform within the aperture, and a platen between the platforms. Optionally, the ends of the aperture may be curved. A first actuator system may be operable to move the platen from a raised position to an intermediate position, and a second actuator system may be operable to press the platen downwardly from the intermediate position onto a workpiece within the aperture. Some modular presses may include conveyor rolls and a third actuator system to raise and lower the conveyor rolls. In some embodiments, the actuator systems may be pneumatic actuator systems. Corresponding methods and systems are also described herein.

摘要:
A pneumatic press with high slide acceleration and velocity is equipped with an arrangement trigger mechanism for holding the slide, upper die, and punch in place until air pressure force in tons is exerted against slide opposite the upper die and punch. When the trigger mechanism releases the slide, upper die, and punch in a short travel the velocity is very high. This will permit the punch to enter the part material at the strain rate of the material, thus eliminating burrs, reducing fatigue initiation sites on the part material surface where the punch goes through the material. Also will permit forming parts of uniform thickness, impact powder titanium to form sheet, and stamp parts against flat sheet of polyurethane with punch having the shape of the part.
