摘要： A press that includes a push rod (12) that can be pushed downward to cut and mold miniature components, has a small size and a minimum number of components, and can be easily and precisely controlled. The push rod has a largely upwardly-facing shoulder (140) that lies in a chamber that can receive pressured hydraulic fluid to push down the push rod. A piezoelectric actuator, or piezoactor (18), moves a piston (20) that lies in a pressure cylinder. One end of the pressure cylinder holds hydraulic fluid (130), and when the piezoactor pushes the piston it pressurizes the hydraulic fluid therein. Pressured hydraulic fluid in the pressure cylinder flows through a passage (23) to the rod chamber to press down the push rod. The cross-sectional area of the pressure cylinder is many times greater than the cross-sectional area of the push rod shoulder so slight movement of the piezoactor is magnified many times by the hydraulic fluid to move the push rod with a long stroke.

摘要： A press for pressing pulverulent materials, in particular metal powder, having an eccentric crank drive, which has at least one connecting rod and a crankshaft and a gearwheel which is connected thereto in a rotationally fixed manner, for driving an upper punch unit. It is possible to drive the gearwheel via at least one worm drive of at least one motor. An electronic control unit is also provided. In this press, the electronic control unit is designed for reversing operation of the crankshaft.
摘要翻译：一种用于压制具有偏心曲柄驱动装置的具有至少一个连杆和曲轴的粉末材料，特别是金属粉末的压力机，以及以旋转固定的方式与其连接的齿轮，用于驱动上冲头单元。可以通过至少一个电机的至少一个蜗杆传动来驱动齿轮。还提供电子控制单元。在该压机中，电子控制单元被设计成用于使曲轴反转。
