    • This invention is intended to provide a large-capacity servo press apparatus driven by multiple motors, the servo press apparatus enabling a drive at a high efficiency and with reduced torque pulsations in a simple structure. The disclosed servo press comprises a slide that is moved up and down by a plurality of crank structures (including eccentric rings and connecting rods), main gears that drive the crank structures, a plurality of drive gears interlinked with the main gears directly or indirectly, intermediate gears interlinked with the main gears directly or indirectly, and servo motor sets connected to drive shafts to drive the drive gears. In each of the servo motor sets, a plurality of servo motors are directly connected to each servo motor shaft.

    • 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.
    • 多个封闭气缸装置设置在压力机的摇枕和包含液压成形装置的下模的床之间。 上模具附接到压机的滑块上。 上模具和下模具一起形成具有所需模制产品的外部形状的空腔。 闭合块可在滑动件和压力机的顶部之间的第一位置和避免滑动的第二位置之间移动,允许滑块从冠部自由移动到下模具。 当液压成型材料放置在下模中时,上模降低。 闭合块配合到其第一位置,从而限制滑块沿垂直方向的移动。 内部工作压力由待模制材料内的流体提供。 闭合气缸装置基于内部工作压力提供压力,以将空腔保持在期望的形状,防止上模具和下模具被内部工作压力分离。
