摘要： A platen press and method for operating a platen press that includes a fixed upper bolster (10) and a lower movable bolster (12) between which is positioned a plurality of platens (14). Fluid operated jack cylinders (17) are used to move the movable bolster to a closed position whereas separate main or clamping cylinders (16) apply a clamping force to the platens when the press is closed. A first source of pressurized fluid (104, 104’) supplies pressurized fluid at first pressure to the jack cylinders during a press closing step. A second source of pressurized fluid (134) at a second pressure, lower than the first pressure prefills (via prefill valves (146)) the main cylinders during the closing step. When the press is closed, the communication of the second source of pressurized fluid to the main cylinders is terminated and the first source of pressurized fluid is communicated to the main cylinders in order to generate the clamping force. The first source of pressurized fluid is a high pressure low volume source such a positive displacement pumps (104, 104’) used in connection with an accumulator (172). The second pressurized source is a high volume, low pressure source such as a centrifugal pumps (134), an accumulator (200) fed by a fluid pump (204) or a flow intensifier operated by fluid pump.
摘要翻译：一种用于操作压板机的压板机和方法，所述压板机包括固定的上垫板（10）和下移动垫板（12），所述压板机定位在多个压板（14）之间。流体操作的千斤顶气缸（17）用于将可移动的摇枕移动到关闭位置，而当压力机关闭时，单独的主缸或夹紧缸（16）对压板施加夹紧力。加压流体（104,104'）的第一来源在压力关闭步骤期间将第一压力的加压流体提供给千斤顶缸。在关闭步骤期间，第二压力的第二压力源（134）低于第一压力（通过预充阀（146））主缸。当压机关闭时，第二压力流体源与主气缸的连通终止，第一压力流体源与主气缸连通以产生夹紧力。加压流体的第一来源是高压低体积源，例如与蓄能器（172）结合使用的容积式泵（104,104'）。第二加压源是高流量的低压源，例如离心泵（134），由流体泵（204）供给的蓄能器（200）或由流体泵操作的增压器。
