Abstract: In order to overcome the problem that the traditional bending die needs to be designed according to the kind of workpiece, and the problem that different bending dies can't be used, a kind of adjustable and indentation bending machine die is designed, and the working characteristics of the die are expounded. The mold has been applied to the actual production, not only effectively reducing the cost, reducing the working strength and bending the workpiece, but also reducing the burr, meat and other damage of the workpiece, so as to improve the appearance quality of the bending parts.
