摘要

The slide adjuster for a press has a slide adjusting screw (4) connected to a connecting rod (3) fixed to the eccentric portion (1a) of a crank shaft (1). A worm wheel (10) at the periphery of the screw is fixed w.r.t. vertical movement in the press crown (2). A press slide (30-32) is threaded onto the periphery of the lower end of the screw and has a piston (33). An oil pressure chamber (35) is formed between the bottom of the piston and the slide. A control valve (38) controls the level of pressure applied to the pressure chamber.
