摘要： A bending apparatus reciprocates at least one of an upper table to which a punch is mounted and a lower table to which a corresponding plurality of adjacent divided dies are mounted. At least one bending angle detector is provided between the dies to detect a bending angle of the workpiece. A main body inserts the bending angle detector into a gap between the dies and withdraws the bending angle detector from the gap between the dies. A lift is biased upward by a first elastic body and is configured to be pressed downward by the workpiece at approximately a center of a groove portion of the dies. The lift includes a first engagement member. A rotor support is biased upward by two second elastic bodies having smaller biasing forces than the first elastic body. The rotor support includes second engagement members. Two rotors are provided on opposite sides of the groove portion at an upper portion of the rotor support. The two rotors include workpiece contacts that contact the workpiece. Links rotatably engage the first engagement member to stop an upper end of the lift in a position lower than an upper surface of the dies, and rotatably engage the second engagement members to position the workpiece contacts below the upper surface of the dies. A bending angle calculator converts rotating amounts of the two rotors into bending angles of the workpiece.

摘要： When a workpiece W whose bend angle is to be measured is slid and pressed on to a rotor (9) in a state where the workpiece has been caused to abut on a first supporting member (7) which is a reference face, the rotor (9) rotates about a rotation center shaft (31) provided on a second supporting member (29), so that the bend angle is measured by reading the rotation angle of the rotor 9 by a detector (39). At this time, the height position of the first supporting member (7) relative to the rotation center of the rotor (9) is adjusted so that the rotation center is positioned within a contacting range R of the workpiece W and the rotor (9). Incidentally, prior to bend angle measurement, the rotor (9) is rotated such that a projection (33) is caused to abut on a stopper (35) provided on the second supporting member (29), thereby performing a calibration. A bend angle measurement can be performed easily, quickly and accurately using a small-sized and light apparatus.
摘要翻译：当要测量弯曲角度的工件W在已经被工件抵接在作为基准面的第一支撑构件（7）的状态下滑动并压向转子（9）时，转子 9）围绕设置在第二支撑构件（29）上的旋转中心轴（31）旋转，使得通过由检测器（39）读取转子9的旋转角度来测量弯曲角度。此时，第一支撑部件7相对于转子（9）的旋转中心的高度位置被调整为使得旋转中心位于工件W和转子（9）的接触范围R内，。顺便提及，在弯曲角度测量之前，使转子（9）旋转，使得突起（33）抵接在设置在第二支撑构件（29）上的止动件（35）上，从而进行校准。弯曲角度测量可以使用小型轻便的设备轻松快速准确地进行。

摘要： An angle detecting head provided with an emitter and a pair of receivers is rocked, and a bent surface of a workpiece bent by a punch and a die of a bending machine is irradiated with a measurement light from the emitter, a reflected light is received by the pair of receivers, and a bending angle of the workpiece is obtained from a peak value of the light received by the respective receivers. The angle detecting head is movable parallel to the die, is movable in a direction close to and away from the workpiece, and is movable in a direction in which the die is raised/lowered. The angle detecting head is positioned in an optimum angle measurement position of the workpiece and the bending angle is measured. Moreover, the bending machine presses the workpiece to the vicinity of a target angle, measures the bending angle of the workpiece during final pressing, removes pressure to bring the workpiece to an unloaded state, measures the bending angle of the workpiece, and obtains and stores a difference between the final pressing angle measured value and the unloaded angle measured value as a spring-back amount.
