    摘要： A high-speed pressing machine comprises a receiver filled with compressed gas. A piston with the piston rod at which end there is fixed a crossbeam with the working tool, and the piston moves in a central portion of the receiver space. Power cylinders are provided to return the crossbeam with the working tool to the initial position and are rigidly fixed within the receiver space. This permits cutting the time between the tool operations and raising the number of work cycles of the machine per time unit.

    摘要： A method for producing high hydraulic pressures for rapidly moving press pistons using a pressure transducer, for example, a piston of two distinct diameters moving in associated cylinders, comprises storing gas at high pressure in a storage container and feeding the high pressure gas to the pressure transducer during the operation thereof. The primary or large diameter part of the transducer is connected to a gas chamber under high pressure. The gas chamber is supplied with the gas at high pressure by a separate pump. The transmission ratio of the gas pressure to the liquid pressure in a pressure transducer varies between (1 to 2 and 1 to 5) 1:2 and 1:5. The apparatus includes an arrangement in which there is a second pressure transducer which is connected to the first transducer for effecting the return stroke thereof and which includes a secondary side which is in communication with the secondary side of the first transducer during the forward stroke thereof. During the return stroke, the secondary side of the second transducer is fed, for example, from an air vessel under pressure while the primary side is in communication with a high level pressure storage tank.
