摘要： A loader and unloader for a plate roll machine has an extensible boom extending generally horizontally over the plate rolls of the machine from a stationary support frame to which the boom is pivoted at one end for vertical movement over the rolls. The boom telescopes through the action of a hydraulic cylinder from a retracted position in which the free end of the boom overlies the plate rolls to an extended position in which such free end extends outwardly beyond the plate rolls. Additional fluid cylinders pivot the boom vertically. A plate support carriage is pivoted to the free end of the boom for fore-and-aft tilting movement. The carriage has one or more rollers extending lengthwise of the boom for engaging and supporting a rolled plate at its upper inside surface. The boom is retracted and positioned vertically for supporting the plate as it is rolled in the plate rolls. The boom is extended while supporting the plate to remove the rolled plate endwise from the plate rolls, and is lowered while extended to lower the rolled plate to a support surface and disengage and withdraw the carriage from the plate.
摘要翻译：用于平板辊机的装载机和卸载机具有从固定的支撑框架大体上水平地延伸到机器的板辊上的可伸缩臂，在该固定支撑框架处，悬臂在一端枢转以在辊上垂直移动。起重臂通过液压缸的作用从缩回位置伸缩，在缩回位置，起重臂的自由端覆盖板辊到延伸位置，在该延伸位置，这种自由端向外延伸超过板辊。附加的液压缸垂直地枢转吊臂。板支撑托架枢转到悬臂的自由端以进行前后倾斜运动。滑架具有一个或多个辊，该辊沿悬臂的纵向延伸，用于在其上部内表面处接合和支撑轧制板。吊杆缩回并垂直定位，以便在板材在板卷中滚动时支撑板材。悬臂延伸，同时支撑板，从板辊端向移除轧制板，同时下降，同时延伸以将轧制板下降到支撑表面，并使托架从板上脱离和退出。

摘要： A fluid-mechanical drive for a press brake incudes two lever members, pivotally connected between their opposite ends to two corresponding end frame members of the press brake. A pair of hydraulic cylinders pivotally connect one end of each lever member to the upper blade at spaced positions,. The opposite end of each lever member is mechanically connected to the upper blade so that upon simultaneous extension of the two fluid cylinders, a direct downward force is applied to the upper blade at two spaced positions along the blade by such cylinders and a downward reaction force is applied through the lever members and mechanical means to the upper blade at two other spaced positions along the blade to drive such blade downwardly through its working stroke into coaction with a lower blade. In one embodiment, the mechanical means are link members, each pivoted at one end to the upper blade and at the other end to a lever member. In another embodiment, the mechanical means is an eccentric formed as the opposite end of each lever member, with the eccentric being offset from the pivot axis of the lever member and operating within a recess of an upper extension of the upper blade.
摘要翻译：用于压制机的液力机械驱动器包括两个杠杆构件，它们在它们的相对端之间枢转地连接到压制机的两个对应的端框架构件。一对液压缸以间隔开的位置将每个杠杆构件的一端枢转连接到上刀片。每个杠杆构件的相对端机械地连接到上刀片，使得当同时延伸两个流体缸时，直接向下的力通过这些气缸沿着刀片的两个间隔位置施加到上刀片，并且向下的反作用力通过杠杆构件和机械装置施加到沿着叶片的两个其它间隔位置处的上叶片，以将这种叶片向下通过其工作行程以与下叶片共同作用。在一个实施例中，机械装置是连接构件，每个连杆构件的一端枢转到上部刀片，另一端枢转到杆构件。在另一个实施例中，机械装置是形成为每个杠杆构件的相对端的偏心件，偏心件偏离杆构件的枢转轴线并且在上刀片的上延伸部的凹部内操作。
