Abstract
In a motor-operated press mechanism, a rocking link is rockingly supported by a supporting shaft which is pivotally supported by a top plate of a press machine, while a crank shaft which supports a crank is supported on one end portion of the rocking link, and a drive section is provided on another end portion of the rocking link, which, in a press working operation, regulates the position of the rocking link so that the crank shaft, the supporting shaft, and the press ram are substantially on a straight line, and, in a resetting operation, swings the rocking link so that the press ram is moved to a retracting position above the position where it is located in the press working operation.
Claims6

- a press ram coupled to said crank so as to be reciprocated vertically;
- a top plate;
- a supporting shaft mounted on said top plate;
- a rocking link rockingly supported by said supporting shaft;
- a crank shaft supporting said crank and supported on one end portion of said rocking link;
- and
- a drive section provided on another end portion of said rocking link;
- wherein, in a press working operation, said drive section regulates the position of said rocking link so that said crank shaft, said supporting shaft and said press ram are substantially on a straight line, and in a resetting operation, said drive section swings said rocking link so that said press ram is moved to a retracting position above a position where said press ram is located in the press working operation.
