Title:
DOUBLE-ELECTRIC-MOTOR DOUBLE-WORKSTATION SCREW PRESS
Document Type and Number:
WIPO Patent Application WO/2019/196604
Kind Code:
A1
Abstract:
Disclosed is a double-electric-motor double-workstation screw press, wherein two screw pair mechanisms are distributed on two sides of a press, same respectively being a first screw pair mechanism and a second screw pair mechanism; a first lead screw (6a) in the first screw pair mechanism is driven by a resultant movement of a first electric motor (1a) and a second electric motor (1b) by means of a first differential gear train; a second lead screw (6b) in the second screw pair mechanism is driven by a resultant movement of the first electric motor and the second electric motor by means of a second differential gear train; a first slider (8a) and a second slider (8b) operate symmetrically in the press; the transmission modes of the second electric motor and the second differential gear train are switched by controlling a steering switching device, such that the second electric motor can assist the first electric motor to increase the output pressure in a single-cylinder pressing process of the press under the condition of the relative position of two cylinders being convenient to adjust; and when the press operates in an idle state, the first electric motor does not work, and an intermediate process with low power requirements is independently completed by the second electric motor, so that energy is saved, and the installed power of the system is reduced at the same time.
