    Abstract: A press machine includes a bottom dead center position correction control section, a speed state determination section that determines the actual press speed, a control cycle count setting section, and a mode selection control section that selects a single-cycle control mode when the actual press speed is in a changing state, and selects a set multi-cycle control mode when the actual press speed is in a stable state. The bottom dead center position correction control section performs position correction control corresponding to each press cycle in the single-cycle control mode, and performs position correction control corresponding to each control multi-cycle count set by the control cycle count setting section in the set multi-cycle control mode.

    Abstract: A plurality of closing cylinder devices are provided between a bolster of a press machine and a bed containing a lower mold of a hydroforming device. An upper mold is attached to a slide of the press machine. The upper mold and lower mold come together to form a cavity having the shape of the exterior of the desired molded product. A closing block, being movable between a first position which is between the slide and a crown of the press machine, and a second position, which avoids the slide, permitting free movement of the slide from the crown to the lower mold. When a material to be hydroformed is place in the lower mold, the upper mold is lowered. The closing block is fit into its first position, thereby restricting movement of the slide in the vertical direction. A inner work pressure is provided by a fluid inside the material to be molded. The closing cylinder devices provide a pressure, based upon the inner work pressure, to maintain the cavity at the desired shape, preventing the upper mold and the lower mold from being separated by the inner work pressure.
