摘要： A crank driving device for a press designed in serial type eccentric structure. An eccentric element of crankshaft connected to a connecting rod, and an eccentric mechanism to provide a second eccentricity, are separated in the axial direction of the crankshaft. The opposite ends of crankshaft are provided, in respective eccentric holes in a pair of rotatable bodies which rotate synchronously on a basic axial line. The crankshaft is axially displaceable between a position in which it rotates in synchronism with the rotatable bodies and a position in which the crankshaft and the pair of rotatable bodies can be rotated relative to each other. The eccentricity of the device is adjusted by rotating crankshaft and pair of rotatable bodies, relative to each other, and then maintaining the relative angle of the crankshaft and the pair of rotatable bodies at constant value by connecting means after adjustment.
摘要翻译：根据本发明的压力机用曲柄驱动装置设计为串联型偏心结构，其中曲轴的偏心元件和偏心机构给出第二偏心度在曲轴的轴向方向上分离。具体地说，在基本轴线上同时可旋转地支承的一对旋转体的各个偏心孔中，曲柄轴的各轴端部相对旋转自如并且沿轴向相对移动。通过相对旋转的曲轴和旋转体来调节偏心率，调整后通过连接装置将曲轴和旋转体的相对角度保持在恒定值。因此，通过调节曲柄单元和偏心孔的偏心度，可以容易地调节滑动行程，同时将压力保持在恒定水平，这有助于设备的紧凑设计。

摘要： A pusher rod extends lengthwise through the eccentric shaft. An additional disk clutch is located inside of the flywheel, which disk clutch is connected to a shaft section, which engages the pusher rod via a screw thread connection. This allows the drive of the punching press to translatorically shift the pusher rod via the further disk clutch. The pusher rod operates the movement of a locking pin, which locks the eccentric shaft to the eccentric bushing by a corresponding translatoric movement. The pusher rod operates furthermore a braceable coupling disk which transmits the driving force from the eccentric shaft to the drive apparatus of the workpiece feed drive. In order to operate these control units when adjusting the stroke of the press it is merely necessary to operate the machine drive in one or the other sense of rotation causing a corresponding closing or opening of clutches and locking members. No further drives are necessary for generating any control movements necessary for the adjusting of the stroke of the punching press. Furthermore, all control movements originate from the side of the flywheel such that a compact design is arrived at.
摘要翻译：推杆延伸穿过偏心轴。附加的盘式离合器位于飞轮内部，该盘式离合器连接到轴部，该轴部通过螺纹连接与推杆接合。这使得冲压机的驱动能够通过另一个盘式离合器来平移移动推杆。推杆操作锁定销的运动，锁定销通过相应的翻译运动将偏心轴锁定到偏心衬套。推杆还具有将偏心轴的驱动力传递到工件进给驱动装置的驱动装置的支撑联接盘。为了在调整压力机行程时操作这些控制单元，仅需要以一种或另一种其他旋转方式操作机械驱动器，从而相应地关闭或打开离合器和锁定构件。不需要进一步的驱动来产生调整冲压机行程所需的任何控制运动。此外，所有的控制运动都是从飞轮的侧面产生的，从而达到紧凑的设计。

摘要： An eccentricity control device, suitable for use as a slide stroke control device in a press, has a rotary shaft including an eccentric member mounting portion, and an eccentric member mounted on the eccentric member mounting portion. The eccentric member has an outer peripheral surface which is at an eccentricity from the axis of the rotary shaft and sliding surfaces which are held in sliding engagement with both side surfaces of the eccentric member holding portion of the rotary shaft. A screw rod is screwed into the eccentric member mounting portion and extends through the eccentric member mounting portion in a direction perpendicular to the axis of the rotary shaft. The screw rod has both ends rotatably supported by the eccentric member such that a rotation of the screw shaft causes the eccentric member to move in the axial direction of the screw rod together with the screw rod, thereby causing a change in the amount of eccentricity of the outer peripheral surface of the eccentric member with respect to the axis of the rotary member.
