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。

摘要： A machine tool driving device suitable for use in a shearing machine, a press or the like which has a machine tool mounted on a tool support vertically movable along a fixed frame, the device comprising at least a pair of links connected to the support for drivingly imparting vertical reciprocating movements thereto, the pair of links being always disposed symmetrically with respect to an imaginary vertical plane which passes through the center of the tool support plate so that horizontal components of the driving force which is imposed on the support by the paired links are cancelled by each other to allow high precision work.
摘要翻译：一种适用于剪切机，压机等的机床驱动装置，其具有安装在沿着固定框架可垂直移动的工具支架上的机床，所述装置包括至少一对连接到所述支撑件的连杆，用于驱动赋予其垂直往复运动，一对连杆总是相对于穿过工具支撑板的中心的假想垂直平面对称设置，使得由成对连杆施加在支撑件上的驱动力的水平分量是相互取消允许高精度工作。

摘要： A PRESS IN WHICH A LOWER PLATEN RECEIVES A TRUSS OR FRAME AND ASSOCIATE MULTI-NAIL PLATES AND AN UPPER RECTANGULAR PLATEN IN PRESSED TOWARDS THE LOWER PLATEN BY A SINGLE HYDRAULIC PLATEND AND CYLINDER ASSEMBLY WHICH OPERATES THROUGH A PAIR OF LEVER ASSEMBLIES WHICH FULCRUM ON ROLLERS ON THE UPPER PLATEN TOWARDS THE FOUR CORNERS THEREOF. THE UPPER PLATEN IN MOVABLE ON RAILS RELATIVE TO THE LOWER PLATEN AND HAS PLATES TRAVELLING UNDER SURFACES OF THE RAILS SO THAT AN UPLIFT FORCE DURING PRESSING IS TRANSMITTED TO SUCH SURFACES OF THE RAILS.
