A device for measuring angles, primarily for measuring bending angles attained by press brakes and similar when a piece to be worked is bent between upper and lower pressing tools (1), includes an oscillating device (6) that detects the angled position of the piece to be worked. The detection device comprises a rocker (6) that is connected directly to a detecting mechanism (12) such as, for example, a rotating potentiometer. The rocker is arranged to pivot around an axis (5) that runs parallel with the longitudinal axis of the lower pressing tool. In its turn, the axis shaft (5) is supported by a supporting and displacement device (3, 4) that can displace the axle, and thereby the rocker, towards and away from the piece to be worked at an oblique angle to the relative direction of movement of the upper and lower pressing tools. |
