SCREW PRESS Russian patent published in 1996 - IPC

FIELD: mechanical engineering. SUBSTANCE: screw press comprises releasable bad, screw spindle and screw driving rotating nut mounted in the top cross-piece of the bad, and table mounted in the bottom cross-piece. The spindle can move forward and provided with punch-die at the free end. There are two additional spindles that are able to move forward, additional top cross-piece, and driving clamps. The additional spindles are provided with tools at their free ends and two driving rotating nuts. The screw spindles are hollow. The screw spindles with a nut is set in the top cross-piece. The other screw spindle is mounted in the table for permitting counter motion of the axially alined spindles. One of the clamps is interposed between the spindles, and the other is outside of the spindle. The drive of each nut has two conical wheels. One of the wheels is rigidly connected with the nut, and the other is mounted with a spaced relation with respect to the spindle. The wheels interact with two oppositely arranged conical wheels. One of the wheels is mounted on the axle set in the bad. The other wheel is mounted on the output shaft of the reduction gear with a clutch and eccentric disk coupled with an engine through a flywheel. Screws are provided in the table to control alignment of the screw spindle. Flanges for control of location of the conical wheels are mounted in the bad. EFFECT: improved design. 3 cl, 7 dwg
