心検出装置。[Claims for Utility Model Registration] 1. In a heading molding device that performs heading molding using a punch provided on the slide ram side of a die provided on the frame side, a non-contact type proximity sensor is provided on the frame, and the slide A detected portion of the proximity sensor is provided on the ram, and when the proximity sensor and the detected portion face each other near the dead center of the slide ram, the proximity sensor is interposed between the frame and the slide ram. A determination circuit connected to the proximity sensor outputs a signal indicating eccentricity abnormality when the detection signal exceeds a predetermined limit value. An eccentricity detection device characterized by: 2. The determination circuit includes a peak hold circuit that outputs a peak hold signal of the detection signal of the proximity sensor, a limit setting circuit that outputs a reference signal indicating the predetermined limit value, and the peak hold signal and the reference signal. 2. The eccentricity detection device according to claim 1, further comprising: a comparator for comparing .
