摘要： A press machine is provided. Two vertical hydraulic cylinders are arranged on an upper beam plate of a press machine body, and the two hydraulic cylinders correspond to workbenches at corresponding positions in a one-to-one correspondence, constituting left and right working units, and a common mechanical drive unit and a common hydraulic drive unit are set for the left and right working units. The mechanical driving unit is composed of a driving motor through an electromagnetic clutch, an electromagnetic brake and lead screw nut driving mechanism driven by a gear pair. According to the load profiles during the working process of hydraulic press machine, the mechanical driving unit or the hydraulic driving unit are selected to provide energy for the two working units. A control method for the press machine, a press machine execution system and a control method for the press machine execution system are further involved.

摘要： A device and a method for fabricating a ceramic reinforced composite coating based on plasma remelting and injection. The device includes a plasma cladding assembly, a powder feeding assembly, a metal-based substrate, and a thermal infrared imager. The plasma cladding assembly comprises a plasma gun and a plasma generator. A plasma arc generated is used to heat the substrate and form a molten pool on the substrate. The powder feeding assembly comprises a powder feeder configured to feed ceramic particles to the molten pool through a powder feeding copper tube. The thermal infrared imager is configured to acquire an infrared image of the molten pool and acquire an optimal injection position of the ceramic particles according to the infrared image. The optimal injection position is a midpoint between a trailing edge of the plasma arc emitted on the substrate and a trailing edge of the molten pool.

摘要： 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.
