Claims

[Scope of utility model registration request]

A ram a and a die C equipped with a punch b are provided facing each other on a body A and a base body B that face each other, and by moving the ram a up and down, the workpiece is bent by the punch b and the die C. In the press brake, the light emitting/receiving group G is placed in front of the base body B and is separated by the sum of the distance corresponding to the state in which the worker bends at the waist and extends his arms horizontally and the safe separation distance due to the ram stop time. The light emitting/receiving device group G is characterized in that a light emitting device and a light receiving device are arranged facing each other on both sides of the front surface of the base body B, and that a press brake stop signal is output when the front shaft is blocked from light. Press brake safety device.
