摘要： A screw press wherein slides carrying stamping tools are arranged on the frame coaxially with one another for reciprocation in opposite directions and connected to nuts cooperating with motion screws mounted on the frame, provided with flywheels and having right-hand and left-hand threads. A stamping die is arranged on the frame between the slides in such a manner that the splitting plane thereof is aligned with the stamping axis, one die is fixed to the frame and the other die is secured to a slide which is mounted in guides extending in the frame perpendicularly to the stamping axis, and there is provided a mechanism for clamping the dies during stamping. The motion screws are mounted in the frame for axial reciprocation during stamping. The press according to the invention is preferably used for stamping blanks of parts having asymmetrical distribution of metal mass lengthwise of the blank, such as turbine blades, compressor vanes and the like.
