Abstract
An apparatus for adjusting bottom-dead-center position of a slide in mechanical press including a connecting rod 4 connected to a crank shaft 3, and a hydraulic cylinder 15 provided between the connecting rod 4 and a slide 5. The hydraulic cylinder 15 has a piston rod 16 having one end connected to the connecting rod 4, a cylinder body 17 capable of moving relative to the piston rod 16, a hydraulic chamber 27 formed below a piston portion 16A, and a pressure adjusting means 45 connected to this hydraulic chamber 27. An extending member 19 for connecting the connecting rod and the cylinder body is fitted around an outer periphery of the piston rod 16, and the adjustment of the bottom-dead-center position of the slide can be effected as the extending member 19 is extended by the adjustment of hydraulic pressure within the hydraulic chamber 27.
