<p>A press brake includes a first guide rail on a rear face of a lower table, a second guide rail on a front face of the lower table, an ATC device and a first measurement portion movable on the first guide rail, and a second measurement portion movable on the second guide rail. The first and second measurement portions measure a bent shape of a workpiece. The second guide rail has a different cross-sectional shape from that of the first guide rail (or is extended bilaterally asymmetrically to the first guide rail). The first measurement portion includes a first main unit having a sensor for measuring a shape of the workpiece, and a first coupling portion for coupling the first main unit with the first guide rail. The second measurement portion includes a second main unit having an identical configuration to that of the first main unit, and a second coupling portion having a different shape from a shape of the first coupling portion for coupling the second main unit with the second guide rail. In the press brake, the ATC device and a bend measurement device (the measurement portions) can be made coexistent and the main units of the front and rear measurement portions can have an identical configuration.</p> |
