常圧式ノツクアウト機構の安全装置。 Abnormality detection means for detecting whether a product remains on the upper die based on the relative position of the knockout pin and the slide, and an exhaust for exhausting pressurized air inside the cylinder of the cylinder device that applies knockout force to the knockout pin in an operating state to the atmosphere. It consists of a valve and a switching control means that switches the exhaust valve to the operating state on the condition that the slide is in a position outside the knock-out area and an abnormality detection signal is issued from the abnormality detection means, and the control means switches the exhaust valve to the operating state. 1. A safety device for a normal pressure knockout mechanism, characterized in that the knockout force is removed in the event of a knockout mechanism.
