Claims

[Scope of utility model registration request]

A punch body is inserted into the punch guide so as to be vertically slidable, a strong strip spring is interposed between the upper end of the punch guide and a punch head formed at the upper end of the punch body, and the punch guide is attached to the upper part of the turret.
A lift spring is stored in a lift spring housing formed in the upper part of the turret, and the lift spring applies an upward spring force to a spring collar that supports the outer peripheral edge of the upper end of the punch guide from below. A magnetic sensor is attached to the collar, and a magnet row is provided on the inner wall of the lift spring storage portion so as to be close to and face the magnetic sensor,
A position detector that detects the position of the spring collar based on the pulse output from the magnetic sensor is connected to the magnetic sensor, and the lowest position of the spring collar is determined based on the spring collar position signal from the position detector. A scrap lifting detection device for a punch press machine, which comprises a scrap lifting determining means for outputting a scrap lifting judgment signal when compared with a reference position and higher than the reference position by more than an allowable value.
