Description of the Related Art A slide drive of a mechanical press according to the prior art includes a drive gear provided on a drive shaft by the power of a drive source, and an intermediate shaft having an intermediate gear which meshes directly with the drive gear or with the drive gear. Via a main gear that meshes via a pinion provided on the shaft, it is transmitted to a crankshaft or eccentric shaft instructed to be rotatable on a bearing member provided on the frame, and is rotatable on an eccentric portion of the crankshaft or eccentric shaft. There is a slide drive device that moves a slide up and down at a constant speed (sine) stroke shown in FIG. 3 via a connecting rod connected to the slide rod.

In the above-mentioned prior art, both the slider mechanism in the unequal speed stroke and the slide drive device in any of the eccentric link mechanism and the knuckle mechanism are required.
The structure is complicated as compared with the slide drive device having a constant speed stroke, and therefore, a lot of time and money are required for manufacturing.

Further, in a slide drive device having a constant speed (sine) stroke, it is necessary to reduce the speed near the bottom dead center of the slide stroke and to make the stop time longer for press working, so that the top dead center and the bottom dead center of the slide stroke are required. And the acceleration is
In particular, a break drive is added at the bottom dead center side, and a slide drive device with a non-constant speed stroke of the slide is required.

However, in the above-described slide drive device of the link (slider mechanism and eccentric link mechanism) and the knuckle mechanism at an irregular speed stroke, the speed and acceleration on the top dead center side are large irrespective of the press work area. It is difficult to increase the speed. From these facts, as for the slide stroke of the slide drive device, the speed near the middle point of the slide stroke is large due to press working, but the speed near the top dead center and bottom dead center is correspondingly small, and the top dead center and bottom dead center are small. A modified sine stroke in which the acceleration at zero becomes zero is desirable.
