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.

The present disclosure provides a method to assemble castings for use in a press brake. A modular press brake is also provided, the modular press brake having a socket connection between the base rail and the bending rail. The press brake is also comprised of a measuring tool having a magnet to engage and disengage from the press brake. An extension allows for cutters to travel from the press brake onto the extension and better cut or bend wider sheet metal. The press brake may be comprised of a stopper pivotable about an axis to quickly prevent or allow the passage of sheet metal in the press brake. The modular press brake is comprised of rails, extruded and fitted into one another. Adjacent rails can be secured to one another by means of fasteners, such that the press brake can be of any length as desired.
