Screw press for e.g. turbine blades - has stamping die arranged on frame between slides so that splitting plane is aligned with clamping axis

摘要

The screw press is provided with flywheels and has 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 is aligned with the stamping axis. One die is fixed to the frame and the other is secured to a slide which is mounted in guides extending in the frame perpendicularly to the stamping axis. 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 is preferably used for stamping blanks of parts having asymmetrical distribution of metal mass lengthwise of the blank, such as turbine blades.
