Abstract
PURPOSE: To escape back-stop up to a desired position and obviate the interference of the back-stop even with the work of any shape by adding dogs, limit switches and some electronic circuits to a press brake.
CONSTITUTION: The hydraulic cylinder 40 of a press brake 30 is extended when the control signal PC1 is high level (H) and is retreated when the control signal CP2 is 1. The cylinder 40 is stopped when the signals PC1, PC2 are both low level (L). The plate bending work is accomplished by extending the cylinder 40 to lower a punch holder 41 down to the bottom dead center position determined by a stopper 37. When the holder 41 abuts against a stopper 35, a relay RX1 is energized. The escape command E of a back-stop 57 is set at H or L in an E command register 21 by a central processing unit CPU. It is made L when this comand E is O and H when 1 and the control unit 10 holds the stop 57 in the current position when the command E is O and retreats the same when 1.
