Abstract

PURPOSE:To provide a titled automatic setter of improved balancing work of slide weights by so constituting the device that the set pressure of a regulator valve can be regulated automatically in accordance with the no-load operating current value and load operating current value of a main electric motor. CONSTITUTION:To balance the weight of a slide 3, a main electric motor is operated to operate the machine under no load. When the current value in accordance with this stabilizes, the 1st signal 26 is inputted to a microcomputer 18, and the voltage responding to the no-load operating current value of the main motor is read and stored. Next, a punch 24 is mounted to the slide 3, and the 2nd signal 27 is inputted to the computer 18. From an A-D converter 17, the voltage responding to the load operating current value of the main motor is kept outputted. When the voltage supplied to a servomotor 23 is changed, the set pressure of a regulator valve 11 changes, and the air pressure to be supplied into the air chamber 9 of an air cylinder 5 changes; therefore, the balancing force by the cylinder 5 is increased or decreased. With an increase or decrease in this balancing force, the operating current value of the main motor increases or decreases and when the operating current value coincides with the no-load operating current value, the weight of the slide is perfectly balanced.
