WIPO Patent Application WO/2012/169461
Kind Code:
A1
Abstract:
This press brake is provided with: a first guide rail on the rear surface of a lower table; a second guide rail on the front surface of the lower table; a movable ATC device and first measurement part on the first guide rail; and a movable second measurement part on the second guide rail. The first and second measurement parts measure the bending shape of a workpiece. The second guide rail has a different cross-sectional shape from the first guide rail (or the second guide rail and the first guide rail are provided asymmetrically on the front side and rear side). The first measurement part is provided with a first main part having a sensor that measures the workpiece shape and a first linking part that links the first main part to the first guide rail. The second measurement part has a second main part that has a structure identical to the first main part, and a second linking part that that has a shape different from the first linking part and links the second main part to the second guide rail is provided. With this press brake, an ATC device and bending measurement device (measurement parts) can be made to coexist, and the main parts of the measurement parts on the front side and rear side can have the same constitution.
