description In a press working apparatus, while a servo motor is acting, an upper die is made to come close to a lower die and press working of the first time is conducted on a steel plate. A slider is raised to a movable punch preparation position. A movable punch is protruded from a die face of the upper die by width and locked by a mechanical lock. The upper die is made to come close to the lower die again and the steel plate is pushed with the upper die and at the same time an additional worked portion is pushed and deformed with the movable punch so as to conduct press working of the second time. After the movable punch has been retracted, the slider is raised.
