    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 geared drag link-slider-crank press mechanism is disclosed which includes a slide movable along a path between first and second positions defining a slide stroke. The slide is driven through a geared drag link and slider-crank mechanism including a geared slide crank having a link connected between the crank and slide so that rotation of the slide crank imparts reciprocating movement to the slide. Rotation of the geared slide crank is achieved by a drag link mechanism including a second crank rotated at constant speed and a third crank driven by the second crank at a variable speed. The third crank includes a gear in driving engagement with the geared slide crank, whereby rotation of the second crank at constant speed imparts variable speed rotation to the geared slide crank. Desired slide velocity and motion characteristics are achieved by providing for the driving and driven gears of the mechanism to have a ratio of rotation other than 1:1.

    摘要： In a press, particularly a transfer press, having a multi-point drive to the ram from pairs of crank wheels, the crank wheels in each pair are arranged coaxially in oppositely rotating pairs and are connected to spaced points on the ram by mirror image linkages which may be a simple connecting rods or compound linkages. In a transfer press, each tool may be mounted on a separate ram provided with such a drive.
