Abstract: The press (1) for processing with high precision articles such as parts of microelectronics comprises a support (2), conveying means for conveying and positioning, relative to the support, the articles to be processed and a ram (6) to which at least one tool (8.1, 8.2, 8.3) can be mounted for processing the articles. The drive means for moving the ram (6) and the support towards and away from each other comprise at least one screw spindle (68.1) which interconnects the support and the ram for moving the support and the ram towards and away from each other through rotation around the axis of rotation of the screw spindle (68.1) in the direction of the axis of rotation of the screw spindle. The press (1) further comprises a motor for driving the screw spindle (68.1).

Abstract: This invention provides an electric powder molding machine capable of controlling a molding pressure accurately and carrying out a regulating operation simply while a die/punch mechanism is replaced by another in accordance with the changed molding conditions. This machine is provided with a die/punch mechanism consisting of a die and upper and lower punches which define a force space, and which are disposed so that the die and punches can be moved relatively for compression molding a powdered material packed in this space, a driving mechanism having upper and lower driving parts for operatively connecting the punches to a servomotor, a means for detecting a molding pressure occurring as one or both of the punches are moved with respect to the die by the driving mechanism, and a means for controlling the drive of the servomotor on the basis of an output signal, which is representative of an actual molding pressure, from the detecting means so that the molding pressure attains a predetermined level.

Abstract: A screw press has a rotary screw (5), a flywheel (8) that turns without interruption in one direction of rotation, a hydraulically controlled friction clutch whose coupling disk (12) establishes a frictional connection between the screw (5) and the flywheel (8) to produce a working stroke, and a restoring rotary drive (15; 23) for moving backwards a tool carriage (3) that moves back and forth in the swept volume inside the machine body. To compensate for the weight of the tool carriage (3), the tool carriage (3) is connected to pneumatic cylinders (13) that have an accumulation-compression chamber (27), a cylinder chamber (26a) at the top side of the piston and a cylinder chamber (26b) at the bottom side of the piston. In order to improve the operation of this screw press, in particular reducing the energy required to brake the tool carriage (3) after its return stroke, its weight is compensated in a controlled manner depending on the speed of the piston (31) during its return stroke, and the air displaced during the return stroke of the piston (31) or tool carriage (3) is throttled.

Abstract: Double action screw-press in which the mechanism (23) for braking the external slider (9) when it approaches the lowermost position is mounted on the butt-end surface of said slider. The mechanism (23) includes a plate (24) provided with an arrangement for movement along the longitudinal axis of the screw (3), four elastic elements (31) mounted on the plate (24), two of which are kinematically connected, through a traverse (26), to a second stop (30). The latter is rotatably mounted in the traverse (26) and interacts, by its end face, with the end face of a first stop (22). The press is further provided with a third stop, rigidly connected to the frame (1) and interacting with the plate (24) when the external slider (9) approaches its lowermost position.
