Document Type and Number:
Japanese Patent JPS56134021
Kind Code:
A
Abstract:
A device for measuring the fold angle in a sheet metal bending press of the type in which a press head forces the workpiece into the V-shaped groove of a die block, the fold angle measuring device having one or two spring-loaded feeler rods in contact with the workpiece laterally outside the bending edge of the press head, the feeler rod, or rods, being connected to an indicator or transducer of the resistive, capacitative, or photoelectric type, for a readout and/or an electrical output signal usable in a feedback circuit of the press controls. The components of the device are arranged in the cavity of a narrow, block-shaped housing which has substantially the same outline as the adjoining sections of the press head.
