Abstract:
A punch press device has a lift that can move up and down with respect to a workpiece and a punch that is supported by the lift and can move up and down with respect to the lift. Further, the punch press device has a switching member that reciprocates between a position where the punch is constrained so that it moves down together with the lift and a position where the punch is released so that it moves up with respect to the lift. The punch press device has two electromagnetic solenoids for reciprocating the switching member. The first electromagnetic solenoid moves the switching member in a first direction, and the second electromagnetic solenoid moves the switching member in a second direction opposite to the first direction.
