Abstract

PURPOSE:To adequately adjust the pressure in the balancer according to die weights by so constituting the unit that a slide position detecting means is provided to crown vertically movably and the pressure in the counter balancer is controlled by the stroke of this detecting means. CONSTITUTION:In the unit of controlling the pressure in the pressure chamber 7 of a balancer 4 which supports the weight of the slide 2 provided between the crown 1 of the press machine and slide 2 by providing the slide mounted with a die 8 to the crown 1 vertically movably by way of connecting rods 3, the position detecting means 9 of the slide 2 is suspended to the crown 1. Since said detecting means 9 is so constituted that the air pressure in the pressure chamber 7 of the counter balancer 4 is automatically regulated to the value meeting the die weight, the pressure in the pressure chamber 7 may be controlled even if the stop position of the slide 2 deviates as in conventional methods and the unit may be made compact.
