BENDING METHOD AND DEVICE THEREFORE

摘要

In the detector main body (29) of a bent angle detector, a pin shaft (35) having a first locking member (39) is constantly urged upward at substantially the center of a groove in a die (D) by a first spring (41). In the detector main body (29), a rotor support member (47) having second locking members (61, 63) is constantly upwardly urged by two second elastic bodies (49) having a smaller urging force than that of the first spring (41). In the upper region of the rotor support member (47), two rotors (51) are positioned on opposite sides in the direction of the groove width of the die (D) and journaled. A rotatable link member (43) engaging the first locking member (39) and second locking members (61, 63) stops the front end of the pin shaft (35) at a position below the upper surface of the die and positions the two rotors (51) at a position below the upper surface of the die.
