HYDRAULIC PRESS Russian patent published in 2010 - IPC B30B11/02 B30B15/22 B30B1/32 C06B21/00

Abstract RU 2393091 C2

FIELD: process engineering.

SUBSTANCE: invention relates to material forming and can be used for forming powder-like thermoplastic explosive compositions. Proposed press comprises plate, working cylinder with plunger, working cylinder pressure line, return cylinders, hydraulic unit and program control device. Hydraulic unit comprises motor connected with frequency converter, two hydraulic pumps, variable throttle in working cylinder drain line and analog pressure transducer in working cylinder pressure line. Press incorporates hydraulic lock, electrically-controller hydraulic control valves and press plate top position pickup. Second hydraulic pump pressure line is connected via electrically-controller hydraulic control valve to first inlet of hydraulic lock. Its second inlet is connected with return cylinders working chambers, and its outlet communicates with working cylinder pressure line. Program control device incorporates pressure control unit.

EFFECT: expanded operating performances.
