精度の加工をすることができる。(Effects of the Invention) In the present invention, as described above, the two punches are advanced simultaneously by the two cam surfaces of the punch drive cam, so that two burring operations can be performed simultaneously with one stroke of the upper die. and can work efficiently. Since this mechanism can process even workpieces with different diameters and angles of the burrings on both sides, it can be applied to a wide variety of products. Furthermore, the resistance of the workpiece acting on the two punches and the pressing force of the punches acting on the die and die drive cam are almost balanced on the left and right sides.
High-precision processing is possible without causing distortion or misalignment in each part of the mold.
