Abstract
Abstract 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.

Claims Analysis
Total Claims: 3
Claim 1
Independent Claim
195 words
A high-speed pressing machine, comprising: a bed, a base mounted in said bed on shock absorbers; a receiver fixed on vertical pillars over said base, the inner space of said receiver being filled with compressed gas; a pistoN disposed within the space of said receiver and capable of movement; a piston rod one end of which adjoins said piston; a crossbeam secured on the second end of said piston rod extending beyond the space of said receiver; a working tool fixed on said crossbeam, the latter having at least two cylindrical through holes; at least two power cylinders rigidly fixed within the space of said receiver; pistons moving inside said power cylinders; piston rods each of which adjoins through one end thereof said piston, while the other ends are let through the holes in said crossbeam which serve to return said crossbeam into its initial position; stops secured on the ends of said piston rods, to retain said crossbeam thereon, said power cylinders having pressure spaces over their pistons, said spaces being connected with a drive to pressurize the medium thereinto, and pressure spaces under their pistons, which communicate with the space of said receiver.

Claim 3
Dependent Claim
34 words
A machine as in claim 1, wherein formed at the bottom of the receiver space is a damping recess serving to quench the excessive energy of impact during the working stroke of the piston.
