    Abstract: A pressing tooling machine, including one or two punches, a die including sectors that can separate from each other but are connected to a shared primary portion, and a ring surrounding and holding the sectors, against which it is adjusted by tapered surfaces, and the altitude of which varies owing to the rotation of a crown provided with a surface in relief. When compression is finished, stripping is preceded by a slight separation of the sectors, which makes it possible to release stresses in the compressed piece and avoid many risks of damaging the piece. The sectors are made resistant by inserts made from a hard material, generally removable and able to be machined to an exact profile of the pieces to the formed.

  • Patent number: 7393193
    Abstract: A system is capable of making a metallic product with robust mechanical and electrical properties. The system includes a pressing stage configured to compress powder (e.g., MMC material) to form a green compact from the powder, a sintering stage configured to sinter the green compact to form a sintered structure from the green compact, and a consolidation stage configured to apply electric current to the sintered structure to form the metallic product from the sintered structure. The electric current is in the form of high density, short electric AC or DC pulses and results in consolidation of the sintered structure at grain boundaries to correct defects in the boundaries (e.g., areas of high electrical resistance) without melting the bulk metal to produce the metallic product. Such a system alleviates the need for coining process, which could fracture bonds and thus weaken the structure, following the sintering process.

  • Patent number: 5275056
    Abstract: A gyratory shear material compacting device in which a material sample is placed within a cylindrical mold having a wobble plate. The material sample is compressed by a piston while the mold is simultaneously gyrated. Gyration is achieved by tilting the mold and holding the wobble plate within rollers which revolve around the mold, controlling the selected angle of tilt while imparting oscillatory gyration. The selected angle of tilt of the mold may be precisely controlled at all times, preventing the mold from riding up on the sample, or from coming into contact with the base of the device. The mold is free to advance rotationally. The device is capable of measuring and recording the height of the sample, angle of gyration, and moment of gyration.
