Abstract
Disclosed is a double-motor double-station screw press, comprising two sets of screw pair mechanisms on both sides thereof, i.e., first and second screw pair mechanisms, where in the first screw pair mechanism, a first lead screw is driven by a resultant movement synthesized by first and second motors through a first differential gear train; in the second screw pair mechanism, a second lead screw is driven by a resultant movement synthesized by the first and second motors through a second differential gear train; a first slider and a second slider in the press work symmetrically; a transmission mode between the second motor and the second differential gear train is switched by controlling a steering switching apparatus, such that the second motor can assist the first motor during a single-cylinder pressing process to increase the output pressure, but also it is convenient to adjust a relative positions of two cylinders.
