Abstract:
An electronic angle measuring device for a bending machine for measuring the bending angle between the legs (4) of a sheet (5) using a sensor element (7) is described, which supplies angle-equivalent signals in a contactless manner to a signal processing unit (9), which has a microprocessor and a memory unit and is connected to a digital display (10). To provide simple measuring conditions, it is proposed that the sensor element (7), the signal processing unit (9), and the display (10) form an angle measuring device (6) which is fastenable on the upper tool (1) of the bending machine and is usable as a handheld encoder, and which has a motion sensor (11), which is connected to the signal processing unit (9) and detects the lowering and/or raising movement of the upper tool (1), for triggering the measuring procedure.
