    Abstract: A hydraulic forging press machine and a control method, whereby surging of the forging load or dead zones where the forging speed goes to zero is suppressed, and forging is performed with high precision throughout a wider range than the prior art, from low to high load. Pressure cylinders have a main pressure cylinder configured so working fluid is supplied during forging, and secondary pressure cylinders are configured so supplying and stopping of the supply of working fluid thereto are switched in response to the forging load, head-side hydraulic chambers of the secondary pressure cylinders being connected to a head-side hydraulic chamber of the main pressure cylinder via electromagnetic switching valves. Only the main pressure cylinder is used until the forging load exceeds a set load, and the number of secondary pressure cylinders used is sequentially increased as the forging load increases after the forging load exceeds the set load.

    Abstract: A large number of green veneers for plywood respectively having high water contents and formed in a rectangular shape are vertically laminated to obtain a veneer laminate having a quadrangular prismatic shape. The veneer laminate is located between upper and lower platen members so that two opposite side faces of the veneer laminate vertically form cut face gathering planes. The upper and lower platen members are moved toward each other to apply a pressing force to the veneer laminate. The pressing force applied to the veneer laminate is released or weakened while the water drawn through the cut face gathering planes by the pressing force is dripping downward along the cut face gathering planes of the veneer laminate vertically formed.

    Abstract: A hydraulic press and a method for operating the press in cycles. The aim is to lower energy consumption in a hydraulic press for shaping workpieces and a method thereof. Each cycle has at least one phase in which the storage pressure pS in the accumulator presses hydraulic fluid into a chamber of a hydraulic cylinder in order to move a ram relative to the cylinder, the ram being coupled to the cylinder. In at least one portion of each cycle, a hydraulic pump driven by a motor delivers hydraulic fluid to the accumulator at a charging volume flow rate. The storage pressure pS is adjusted to a reference value PSOLL by setting the speed of the motor to a nominal motor speed nN and to at least one intermediate value nZ, where 0<nZ<nN.

  • Patent number: 8915181
    Abstract: In a mechanical press, the pressure (cylinder force) of a hydraulic pressure chamber of a cylinder-piston mechanism provided in a slide of the mechanical press can be variably controlled with a high responsiveness by a hydraulic pump/motor driven by an electric servomotor, in response to a cylinder force command corresponding to the press load command. Accordingly, even if a die height value is set to a value small enough to cause an overload, the press load can be restricted before the occurrence of the overload, and this can save the trouble of strictly adjusting the die height value. Further, pressure-application time in the vicinity of a bottom dead center can be lengthened, and a breakthrough phenomenon can be suppressed from occurring at the end of pressure application. Still further, because the overload does not occur, pressure oil is not relieved, so that the interruption of a press operation is avoided.

  • Patent number: 8047131
    Abstract: A control apparatus of a press machine in which a motor performance torque is fluctuated in accordance with a rotational angle of the rotating body in the case of rotating the motor at a fixed instruction speed. The control apparatus includes an angle detecting apparatus detecting a rotational angle of the rotating body, a torque determining apparatus determining a necessary motor torque in correspondence to a characteristic of the press machine on the basis of a value of the rotational angle input from the angle detecting apparatus, and a speed adjusting apparatus increasing the rotational instruction speed of the motor to a value more than the fixed instruction speed, at the rotational angle of the rotating body in which the necessary motor torque becomes smaller than a predetermined motor torque reference value.

  • Patent number: 8042461
    Abstract: A pneumatic compressor for the compression of waste comprising a cylinder (1) with a piston (2), which via a piston rod (4) activates a compression plate (3), which is slidably mounted in a compression chamber (5) which has a top door (6) through which waste paper is thrown into the compressor, and a bottom door (7) through which a finished bale can be taken out, which compression takes place in a series of compression cycles, which each time is charged with a new portion of waste, until the waste offers a counter pressure corresponding to the pressure which the piston (2) can exert at a pressure of 8 bars. In 80-90% of the compression cycles necessary for the compression of a bale, the piston (2) reaches its bottom position in the cylinder, and each time the pressure reaches a pressure of 8 bars in the cylinder (1).

  • Publication number: 20110232513
    Abstract: A production system has at least one mechanical press driven at least in part by a flywheel powered by a first motor. The system further includes a second motor which is a servo motor. The power of the first motor powering the flywheel is arranged controlled by a control unit dependent on a function of the power of at least one second motor, the servo motor. In this way, the peak power of at least the first and the second motor may be limited. A method for operating the system and a computer program are also contemplated.

  • Patent number: 7997190
    Abstract: Precise motion of the ram of a fastener press is controlled by high torque and low torque motors for high speed/low force and high force pressing of the ram by the ram, respectively. The high torque motor means drive passes through a bidirectional overrunning clutch. The clutch is controlled by the relative motion of the two separate motor drive speeds of which are regulated by a controller. The clutching motion is therefore controlled only by the relative speed of its drive versus driven components. This provides an extremely smooth and responsive transition between high speed/low force and low speed/high force operation of the ram so that the pressing cycle can be as fast and efficient as possible.

  • Patent number: 7913617
    Abstract: A container with a door forms an operating chamber. A crushing zone within the chamber is defined below by a support and above by a vertically reciprocable ram. A driving assembly raises and lowers the ram to compact a plastic bottle in the crushing zone. A heating element softens the plastic bottle. A programmer is operatively coupled to a plurality of controls for receiving operating instructions and to the heating element and the driving assembly to thereby cause an appropriate cycle of operation for crushing and compacting the plastic bottle.
